Light pollution is a term that is hardly heard by people. There are many kinds of pollutions that are common these days. Water pollution, air pollution and other kinds of pollutions are very commonplace. In spite of the fact that these kind of pollutions are common, people do not bother about this. One other pollution that is rarely thought about is the light pollution. You can go to the website canada 411 to learn about the relevant information and places that can help you understand this fact.

The reason for the rarity with which light is heard about is because the light pollution is not something that can be very life threatening unlike the water and air pollutions. In spite of this, education about light pollutions is important because the light pollution has the potential to destroy the sight of people. These days, there are so many lights that in the night, if one is able to see the buildings that dot the landscape, it looks as if it is still day time.

There are many reasons for the education about light pollutants is important. As the increase in the intensity of the lights increase, it can lead to severe eye strain to the people. The eye strain can lead to early eye damage in any person who is exposed to continuous bright lights.
Other than the eye strain, the bright lights can also cause other problems in the person. They can lead to accidents because of the blinding lights that shine in the face of the person who is driving a vehicle. In fact, the number of accidents has increased because of the fact that there is a lot of light pollution.

Education about light pollution is important also because the night lights in various parts of the world cause the observatories not to be able to identify the starts and the other celestial bodies not to be observed properly. The high intensity lights have caused them to be difficult to identify.

Most everyone knows that the galaxy is an absolutely gargantuan place. Because of this tremendous size, it’s very easy to see how tiny we really are on this microscopic dot that we call the earth. While it may seem huge to us, on the cosmic scale it’s little more than a speck of dust.

The cosmic ballet around us stretches so far, but it can show us many interesting things about our own tiny dot. We can observe how massive amounts of things formed up by tracing their chemical components and watching them slowly spread apart. While a human lifetime is nothing to the stars above, our civilization can watch things change in the heavens and learn about how our own planet formed up all those billions of years ago. Of course, there are also some other lessons we can take in from all of this.

The most important lesson we will ever learn from the cosmos is the utterly beautiful nature of our own tiny pebble. While some people don’t think much about what the earth does for everyone and how hard it is to create such a planet, keep in mind that without earth no one you know could possibly survive. Also, considering how rare planets like earth are, doing anything to hurt the planet is more than just cruel and unjust. It’s more than a little stupid to purposely abuse your own ecosystem when you could be doing something far more constructive with your life.

Why is it important to have a hobby? A person who focuses on earning money and enjoying materialistic benefits will often forget how important other things are. Having a hobby will help the person understand that there is something more important than just enjoying material benefits in life.

One does not have to opt for grand hobbies like astronomy. Of course, the idea of peering into a telescope is a lesson in humility. You will understand how small we are and how we have been chosen by destiny to enjoy our time here. Small matters that often irritate us will become minuscule when we realize how small we are.

Or take the idea of collecting stamps. Once you start collecting stamps, you realize that there is an inexhaustible supply of new ideas in this hobby. Each and every new stamp promises to bring forth another new unknown stamp which may revolutionize the collection. We realize how much time it takes to master something as insignificant as a collection of pieces of paper with the designs printed on it.

Many persons criticize hobbies as being a waste of time. Well, the truth is that time that is spent on trying to earn money can be classified as a waste of time. However, time that helps us understand ourselves and our role on the planet better is definitely not a waste of time. Of course, you have the option of ignoring the philosophical aspects and focusing only on the fun and joy of having a hobby where you can spend some time on productive purposes for some fun and relaxation.

The next time you drop a call on your cell phone or experience problems with your GPS or satellite dish, consider that the culprit just might be solar flares.

In February 2011 Earth’s sun was quite active, launching three solar flares in succession. More of these flares are sure to follow: Scientists note that storms on the sun follows an 11-year cycle and last crested in 2002. This means that a peak is expected to be reached during the years 2012 and 2013.

What does this mean? No one is quite sure; many experts are quick to note that there is no reason to panic, but the potential for widespread disaster is clearly evident:

Power Outages

Solar flares are capable of overloading circuits and causing sporadic power outages. In 1989 Quebec was victim to a nine-hour blackout caused by solar flares.

Communication Interruptions

Electromagnetic storms can knock out satellites and cause communications systems such as pagers and cell phones to be rendered inoperable.

GPS Malfunctions

If satellites are knocked out, GPS receivers will be unable to lock onto signals and will not be functional. This would not only affect the millions of GPS users throughout the United States, but also air traffic.

Domino Effect

Scientists have issued warnings that everything from transportation to government to finance to food and water supplies could be affected as a result of the “domino effect” that could take place if the electric grid were to be compromised.

Fortunately, the Earth is well-protected from these solar storms by its atmosphere and magnetic fields; however, it never hurts to be prepared.

Without the spacecraft Galileo, we wouldn’t know nearly as much as we do about the planet Jupiter.

Launched in 1989, the unmanned spacecraft was tasked with probing and gathering data regarding Jupiter and its surrounding moons, of which there are 63 confirmed.

Named after famed astronomer Galileo Galilei, who discovered the four largest moons surrounding Jupiter, the spacecraft completed 35 orbits around Jupiter and provided scientists at NASA with a wealth of information.

Although Galileo’s mission was terminated in 2003, data analysis is still underway and new information is still being discovered.

Studying Galileo’s data has given us a much better understanding of Jupiter, the largest and one of the most fascinating of the planets that make up our solar system. Some of the more interesting and notable discoveries attributed to the spacecraft Galileo include the following:

• Volcanic activity present on Jupiter’s moon Io is similar to volcanic activity found on our own planet (although there is a lot more of it on Io). This activity is a result of an ocean of magma located below the moon’s surface.
• There may be oceans located beneath the layers of ice that make up the surface of Jupiter’s moon Europa.
• Jupiter is home to violent thunderstorms considerably larger than the ones we experience on Earth.

Galileo’s mission to Jupiter was ended in September of 2003 when scientists deliberately sent the spacecraft hurtling into Jupiter’s atmosphere, destroying it. This was done because Galileo was nearly out of the propellant needed to remain operational, and scientists at NASA were concerned that the spacecraft, if not intentionally destroyed, might accidentally cause damage to Jupiter’s moon Europa.

Many people know at least most of the planets in our solar system but dwarf planets are a mystery. Most of the public did not know they existed until Pluto was demoted to dwarf planet. The International Astronomical Union recognizes five dwarf planets: Ceres, Pluto Eris, Makemake and Haumea.

The International Astronomical Union (IAU) was founded in 1919 to endorse and preserve all phases of astronomical science. The IAU has over 10,000 members and is headquartered in Paris, France.

The IAU has created a three part definition of what is a dwarf planet. The first criterion to be considered a dwarf planet is that the celestial object must orbit around the Sun. Secondly; it must keep a rounded shape due to its own gravitational pull. Lastly, it can not be a satellite or clear its region of neighboring planets. There are five documented dwarf planets, but there is believed to be over thirty more objects considered to be dwarf planets in the solar system.

Ceres was discovered in 1801 by Giuseppe Piazzi and was first categorized as a planet. It is the smallest of all the dwarf planets and only one located in the asteroid belt.

In 1930, Clyde W. Tombaugh discovered Pluto and was considered a plant until 2006. Pluto is the largest entity of all components in the Kuiper belt.

Mike Brown, Chad Trujillo, and David Rabinowitz discovered Eris and Makemake in 2005. Eris is the ninth largest body to orbit the sun and Makemake is the third largest dwarf planet.

Haumea was discovered in 2004 by teams in the United States and Spain. Haumea location is beyond Neptune’s orbit, which makes it a plutoid.

The public knows very little about an interesting part of the Solar System called the Edgeworth-Kuiper or Kuiper Belt. Interest has peaked in this area because it houses dwarf planets and moons. The number of objects in the Kuiper Belt is believed to be more than a thousand.

History

The Kuiper Belt was formally discovered in 1992, but astronomy work from 1930 has helped to support its discovery. Gerard Kuiper is credited with discovering the part of space located beyond the orbit of Neptune. Kenneth Edgeworth is recognized for proposing the notion that celestial bodies exist.

Contents

There are over 70,000 objects located in the belt that are composed of different materials including methane and ammonia. The region was originated due to the expansion of Neptune billions of years ago. The contents within the belt continue to increase and expand.

Pluto is the most recognized KBO (Kuiper Belt Object) due to its former designation as a planet. Triton, a moon of Neptune, and Saturn’s moon Phoebe are located in the belt. Three dwarf planets – Pluto, Haumea and Makemake, reside in the Edgeworth-Kuiper belt. Some of the belt’s contents have satellite sized objects or smaller.

Exploration

Scientists believe they have found configurations similar to the Kuiper belt. Observations from the Hubble space telescope have reported new information. These over 200 million year old, debris discs are clustered around nine stars.

Conclusion

Although the Kuiper belt is an unknown science phenomenon to most, it has an interesting future regarding exploration. Advances in technology should bring more information on the belt and its objects for the future.

Everyone knows that the Sun is a star, but few know other characteristics about the fiery balls. Stars are more than objects that inspire nursery rhymes and twinkle at night. The subject of stars can be very fascinating and informative. The passage below will reveal some interesting facts about stars.

Stars are large amounts of plasma bonded together by gravity. Most stars are estimated to be about 12 billion years old. Stars are made up of hydrogen, helium and other elements. They can be as small as twenty kilometers to over six hundred times bigger than the sun.

Stars are measured in units called a solar mass. One solar mass is equivalent to one Sun from our galaxy. The most massive star is R136a1 that is about 260 solar masses. OTS44 is the least massive star with a solar mass of .013.

A star’s brightness is calculated by their magnitude on the visible spectrum. Sirius is twice as bright as Canopus, the second brightest star.

Most people know that stars that form a pattern are called a constellation. The Big Dipper is debated as being the most popular constellation. The International Astronomical Union (IAU) is the entity that deems the definition of a constellation.

An interesting fact is that the IAU designates what is a former constellation. Former constellations are not on current star charts but are used for chronological study. Argo Navis is a former constellation that was divided into four constellations. Quadrans Muralis originated in 1795, and then was separated into the constellations Bootes and Draco.

Most people know that astronomy is the study of objects whose beginnings are from outside the earth’s atmosphere. Astronomy is one of the oldest natural sciences and acquires information by observing and collecting data about the formation and development of celestial bodies. The majority of information about space objects is retrieved from a type of astronomy labeled observational.

Observational astronomy is the study of viewing and scrutinizing bodies in space with astronomical equipment. This area of astronomy can be divided into subfields due to location on electromagnetic spectrum. Continue to read to view some of these fields in observational astronomy.

Radio Astronomy

A branch of astronomy that uses radio waves to study space. Karl Jansky made the first radio wave discovery in the 1930’s. Radio emissions have been found in stars and galaxies.

Infrared Astronomy

Infrared astronomy is a subfield of astronomy that studies objects viewable infrared radiation. William Herschel’s discovery of infrared light led to this branch of discovery in 1830’s.

Optical Astronomy

Visible Light or Optical is the oldest form of astronomy. This type of astronomy uses telescopes to observe and collect data.

Ultraviolet Astronomy

This subfield of astronomy uses ultraviolet wavelengths observed by earth’s atmosphere to record information. Ultraviolet astronomy is used for blue stars supernova remnants.

X-ray astronomy

X-ray wavelengths are used to study celestial bodies. High-altitude balloons and spacecrafts are used in X-ray astronomy.
.
Observatories

The activity of viewing space happens in an observatory. Observatories are constructed for studying meteorology, geology and astronomy among other sciences. There are three main categories of observatories: ground -based, space- based and airborne.

Ground-based locations use radio telescopes and are positioned on Earth’s surface. They outnumber all other kinds of observatories.  Space-based types are launched into outer space and used in X-ray astronomy. Balloons or airplanes released with astronomical equipment are airborne observatories.

Comets are celestial bodies that travel close to sun; they have a tail and leave a visible path in the atmosphere. Ancient records have estimated the first appearance of comets before the year 1267. Scientists have reported more than 3,000 occurrences of comets, but believe thousands more are in the outer solar system. They estimate that only one comet per year is visible without the help of a telescope.

Comets are composed of ice, dust and carbon-based materials. They contain a nucleus, coma and tail. Comets can be seen only when traveling near the sun. Their rough exterior has gained comets the nickname of “dirty snowballs”.

Their orbit identifies the two types of comets periods; short and long. Short period comets finish their orbit cycle around the sun in 200 years or less. The long period comets orbits range from 200 to thousands of years.

The results for comets are based on a variable of factors. Some comets collide with planet, moons or descend within the sun. Others shatter into smaller pieces due to gravity of large planets and explosive materials within. Lastly, fast moving comets exit the solar system when interacting with other celestial bodies.

Historically comets were known less for their splendor but as a symbol of bad luck. Great comets are bright in appearance and noted in popular culture. Noted below are a few great comets noted by astronomers in the past.

Caesar’s Comet

The Great Comet of 44 BC was viewable for seven whole days. Caesar’s Comet is known as one of the brightest daytime comets on record.

Halley’s Comet

This short term celestial body is viewable from earth every 75 years. The first record of this incident appeared in a Chinese chronicle from 240 BC.

Comet Hale -Bopp

The Hale-Bopp comet is recognized as the brightest comet viewed since the Great Comet of 1811. Alan Hale and Thomas Bopp independently discovered the comet in 1995.

The study of Astronomy and/or Astrology is a very interesting course of study.  For the budding scientist it is a vast abyss, waiting to be observed and for new discoveries to be made every day.  There is just too much going on in the sky.  The desire to be a scientist, especially an astronomer, starts long before the college years.  Everyone knows a kid who just loved to be outside when the sky was clear, with a telescope facing the sky, waiting for the perfect angle to view the Big Dipper.  He will camp out to observe a lunar eclipse and if there is a once in our lifetime occurrence predicted to be in the sky, you won’t be able to keep him away. He is ready and waiting for days, just to get that glimpse.  He can see pictures in books, but nothing compares to watching it in person.

He is fascinated by what he sees when he looks in that telescope.  He is overwhelmed at how the sky comes alive night after night.  There is another world out there.  A world he dreams about becoming a part of, he longs to study it, get to know it, revel in it.  Maybe it is not a world of people driving cars around, rather an entire universe of burning glory in our sky every night.  Stars are moving, burning out, beginning again all over the galaxy all the time.  The study of their perfect dance night after night is a full time job, a career.  To make a career out of watching the perfect waltz, that synchronized dance that occurs in the sky each night, is the culmination of years of looking through that telescope, wishing on those stars.

They say there are millions of stars, millions upon billions of stars in the sky.  What we see when we look into the sky at night, we see a mere fraction of the activity that is going on in the heavens.  The stars are dancing and darting their way through the night.  The amazing thing is that these stars can be located.  Astronomers can pinpoint exactly where a star is in the sky, They have charts and sky maps and coordinates, and for the most part they can tell you where a star is at any given time.  Astronomers have identified clusters of stars, Supernovas, asteroids, millions of bright lights just littering the sky with blinking, twinkling light.  The stars seem to be having one big huge disco party in the sky.

It only stands to reason that someone here on the Earth, millions of miles away from those stars came up with the idea to own them.  It is a charming concept, and of course, someone is making a profit on it.  For a fee, somewhere around $20 you can name a star.  You can actually look at a chart and choose your star.  You name the star, especially cheesy Valentine’s Day gift, perfect birthday gift for a young scientist.  Imagine applying to MIT someday and putting on the application under “miscellaneous”, “by the way, I own a star.  It is named for me.”  Sounds prestigious.  Kids love it, some marketing genius somewhere is sitting back just counting the money.  Who is going to be able to prove which star is theirs, who is going to question you when you show it to them.  But the bottom line is, how cool is it to own one?

Is the ozone layer disappearing?  Are the polar ice caps melting because of global warming?  Is the surface of the Earth one day going to be so hot we won’t even be able to walk on it?  You would think any of that is possible, but is it probable?  Is there really a hole in the ozone layer, and if there is maybe the hole is over China, half way across the world.  Maybe we don’t have to worry about pressure cooking our skin, they do.

What we do know is what we hear and learn from scientists and environmentalists.  They are telling us that we are destroying our own atmosphere.  There are places in this country where you can see the pollution first thing in the morning when you wake up and look out the window.  There it is, hanging in the air like a thick umbrella.  That cannot be good for anyone.

We have definitely cut down on people smoking in our world, but what about the number of cars that are pouring pollution into our air every day?  We have not stopped producing cars, we are mass producing cars.  Where just about 40 years ago most houses were one car households, the average household owns three to four cars.  That is four times the pollution right there.  Factories are literally pouring pollution into our air at an alarming rate.

Yes were are poisoning the atmosphere.  Steps are being taken, but the progress is slow.  You can get a hybrid car that would not burn as much gas, but the cost of one right now is out of most people’s budget.  We need to be more diligent.  We might not be here when it gets really bad, but our great great grandchildren will be, and don’t we want to protect them too?  Don’t we want to do everything to make their world a safe place to live, instead of the smog chamber it is currently becoming?

Unless you are a certified Science geek, a trip to the Planetarium does not seem to make you leap for joy, as of course it does for the Science geeks.  However, you signed on for this trip, off with the entire sixth grade class for the class trip of the year.  You know that you will be carrying about 10 lunches and make numerous trips to the bathroom all day long.  Well you signed on for this and hey, you might actually learn something new.

You arrive at the Planetarium.  The Science geeks can barely contain themselves.  They already have their heads together in search of a new star, galaxy or planet as they are sure that this discovery will happen soon.  You are thinking that you probably lost a lunch or two along the way and now you will have to buy those kids stars and moon shaped chicken nuggets.  They could do worse.

The class is shuffled into the Planetarium.  The lights begin to dim.  You have already been to the bathroom several times, but you are thinking this would be a good time for you to sneak out and use the bathroom yourself, for the next half hour while the Science geeks get their fix and the rest of the class just punches on each other in the dark.  Just as you are about to sneak out, a shooting star passes right by your left ear.  What was that? The dark cavernous ceiling/sky begins to come alive with the different lights of the night.  The stars are shining like ten carat diamonds, as the planets appear to begin a ritual dance they have perfected all those years hanging out together in the sky.

Twenty minutes later you are looking for the DVD of the amazing light show you just saw and planning a popcorn and planet watching party with the Science geeks.  Hey, you actually did learn something new.

Canada’s weather may tend to lean heavily towards cool. It is actually those cold, crisp conditions, coupled with the fact that Canada has very little light pollution and lots of places that have high altitude, that make sky watching very favorable. That’s probably the reason why some of the world’s largest observatories are located in Canada.

Depending on which observatory you visit, you may actually be able to take a tour of the facilities and look through some of the telescopes that are used to study the night sky. You can use Canada 411 to find those observatories that are open to the public and conduct tours.

Even if you can’t actually tour the observatory, that isn’t an excuse not to visit one. Depending on the observatory’s location, you’ll be able to see things in the night sky that you probably had only heard about or seen pictures of. Imagine actually being able to see the Milky Way as it stretches across our galaxy, or make out all the stars in a particular constellation, not just a few of them.

In addition, the observatories, both those open to the public and for tours, as well as those which are not, use the latest in telescopic technology to conduct their research and studies. They keep up with the advancements in this and other technological fields so that their findings will remain accurate. This is very important when studying the cosmos, especially since Canadian observatories are the ones responsible for a large majority of the research that is performed in this area.

If you visit an observatory in one of the higher altitude locations, be sure to dress warmly, even if it is the middle of summer. Temperatures can be cooler at higher altitudes, and you want to be able to stargaze in comfort. Checkon current weather conditions and temperatures.

What’s your sign?  The study of Astrology is felt by some, to literally guide your entire life.  Some woman plan having their babies under certain astrological signs, thereby insuring them a bright and happy future.  Couples plan their weddings on good astrological dates, or steer clear of bad astrological dates.  There are schools of thought for and against the study of astrology and how it pertains to shaping one’s life.

Can the way the planets are aligned really predict how your life will play out?  Does the position of the planets at the time you were born really have an effect on your type of personality or the people you would be most compatible with?  There are believers and non believers.  While there are millions of people born under every sign of the zodiac, not all the people born to a certain sign experience the same effects on their lives.  Can those who do believe mold their lives to conform to the particulars to their sign?  In some cases, yes.  There is something to be said when the alignment of the planets constitutes an entire study in and of itself, astrology.  Astrology is not about the stars, rather about the planets, their position at any given time, and how that affects the way we live our lives.

One can have their entire astrological chart drawn up.  However, you will be given basic information, such as “Aries get along well with Scorpios”, or “you have an easy going personality.”  Unless you are Jack the Ripper, most of these statements could apply to almost anyone.  For the most part, the study of Astrology has its place.  It is probably not a good idea to plan your whole life around your astrological sign, but it can be amusing to consider what parts of that sign pertain to you.  There are other more exact sciences, but astrology might just be the “fun” science.

Looking up into the sky on a clear night is like watching a graceful ballet.  The sky is literally alive with activity.  The stars are glowing, sometimes it looks as though they are blinking one at a time.  Some of them are shooting, rushing by other stars as if to play a game of star tag.  There is the Big Dipper, which always has the Little Dipper in its path, as if the Big Dipper were the parent, watching a small child play in the park.  On clear nights, the Big Dipper and the Little Dipper are clearly defined and something beautiful to see.  On cloudy nights, you can see the stars play a great game of hide and seek, waiting for the clouds to clear so they can shine their brightest and watch us marvel at them.

Then there are the special performances.  Once every couple of years we get to see planets that we normally cannot see.  Get out the telescopes, sometimes these sightings are once in a lifetime, and may not occur again for hundreds of years.  Lunar eclipses are always fun to watch.  It is amazing to fathom the size of the moon and the sun passing in front of or behind one another.  They just look like a couple of spheres, being juggled by some great sky giant, for our enjoyment.

There are the surprise visits.  Sometimes you are just looking up at the sky at the right time.  An asteroid breaks up and blasts of light shoot through the sky.  Sometimes the astronomers let us know when a meteor shower is expected, giving us yet one more chance to experience the wonders of nature.

How often do you go through life never looking up at the sky?  How often have you said you wish there were forms of entertainment that were not so expensive?  Next time the budget is tight and the sky is clear, pull up a lawn chair, grab a drink and get ready for the show.  It is worth every penny.

There are a lot of beginning astronomers that go out and buy their first telescope without even thinking about what they need to buy. Here are some of the things that you should remember when you are choosing your first telescope. These are the right things that you should do when you are buying a telescope.

• When you are choosing your first telescope, a Dobsonian reflector that’s 6” or 8”.  This is going to offer some great results for your money.  For a refractor, one that’s 80mm with a stable mount is also one that is okay for a first telescope.
• You should expect to pay at least $300 when you are shopping for your first telescope. Otherwise you are going to get one that isn’t worth your money.
• Buy an overrated/oversized mount, because mounts have to be sturdy in order to work well.
• Choose an eyepiece that’s at least 1.25” and don’t go with the designs that are 0.965”.
• Get a telescope that is the weight and size that you’re won’t mind taking to the different sites or setting up.
• Select two or three eyepieces that are quality as well as one of the Barlow lenses.  The eyepieces that are good but don’t cost a lot include Plössls and Kellners.

These are some of the things that you should remember when you are buying a telescope for yourself.  They are all important to keep in mind when you are looking at the different telescopes and they will also help you to figure out what one of the telescopes that you should buy. It’s also going to help you to keep from wasting your money on buying the telescopes that aren’t going to give you good results.  Remember the tips for choosing your eyepieces and the mounts and you’ll find that you are getting the best telescope that you can for your money.

One of the planets that has been the source of a lot of mystery and tales is Mars. So what does this planet hold? What are some of the secrets? Here are some of the facts that people have discovered about Mars.

·        It’s the fourth farthest from our sun. it orbits it at a distance that is about 141 million miles, and it takes about 686.93 days on Earth or approximately 1.8807 Earth years to make a full revolution.

·        It’s the seventh biggest planet.  It’s about half of Earth’s diameter and it has about a 1/10th the mass of Earth. Its density is approximately 30% lower than Earth’s. The core of Mars is probably a lot like Earth’s, being mostly iron with some nickel.

·        The planet Mars is small and rocky. Like the other three terrestrial planets – Venus, Mercury, and Earth, it has a surface that’s been changed a lot by impacts from assorted bodies, crust movements, volcanism, and things like dust storms.3

·        The surface of Mars is the most similar to that of Earth than any other planet. It would be a really harsh place for anything to live, however, because the temperatures go from -225 – +60 degrees Fahrenheit, and it’s average temperature of -67.

·        It’s probably our best hope for finding some kind of life other than on Earth. The atmosphere is thin and it’s made up of carbon dioxide, nitrogen, argon, and some oxygen, as well as water.  Water has also been found in liquid on Mars.

It’s really easy to see that Mars is very interesting without all the myths that surround it. It’s constantly being studied and maybe someday we’ll find some life on it.  But until then all we can do is look at it and dream about what might be and what we might find.

When you are looking for telescopes for astronomy, you are going to find that there are three different kinds of telescopes that you can choose from. They all have different features and different things on them for viewing the night sky.  Below you will find explanations of the different telescope types so that you are able to make the choice that is right for you from them.

• Refractor – These telescopes are the ones that you are going to see in department stores. They use the refracting lenses which are housed in the thin, long tubes that are mounted on tripods. They are great for viewing things like the moon, planets, and sun when magnified detail is important to you but you don’t care about brightness.
• Reflector – These are larger telescopes that use mirrors which are housed in larger tubes which are usually mounted in a low mount that’s a rocker style.  This is known as the Dobonian mount.  They’re light buckets and they’re really great for viewing things like star clusters, nebula, and galaxies that are set deep in the sky.
• Compound – These are also known as cadioptric telescopes and they use both the reflecting mirrors and refracting lenses in order to provide the person with a factor that is compact form. These kinds of telescopes include ones made by Maksutov, Cassegrain, and Schmidt, as well as the hybrid designs.

When you are thinking about buying the right telescope, remember the three different kinds that are listed here and ask yourself what you want the telescope for. Remember that the more a telescope does the more expensive it’s going to be. Look at your needs and your budget and you will be able to discover what you will need for your own astronomy studies.

When you have the right telescope for your astronomy hobby, you will discover worlds that you have never seen before.

When you are into astronomy, it seems that there are a lot of things that you can buy for your hobby. But there are three different categories of accessories for telescopes that you can choose from – those that are essential, those that are good to have, and those that are nice but not ncessary. Here are the lists of the three types of accessories for the telescope that you can buy, starting with the ones that everyone who has a telescope should have. Even though the accessories that are in the other two lists are nice accessories, they are extra.

Essential

• Reflex finder – single power
• At three inexpensive eyepieces
• Barlow lens – 2x
• Observing stand or chair
• Red flashlight
• Planisphere or star charts
• Dew shield
• Cover for telescope

Good to Have

• Binoculars(this is something that some people consider to be essential)
• System for dew removal
• At least one expensive eyepiece, maybe two
• Planetary filters set
• Nebula filter – narrowband LP
• Scope dedicated for solar or a solar filter
• Drive system that’s motorized
• Laser pointer – green

Nice but Not Necessary

• Another scope (some people want this!)
• Binocular viewer
• Dome, tent or shelter for telescope
• PDA or laptop for using software to drive your telescope

It’s important to know the accessories that you are going to need when you are using a telescope and those that are nice to have but not ncessary.  This is especially important when cost is a factor when choosing the accessories for your telescope. You want to get the best results from your telescope with the accessories that you can afford and that are ncessary for you to have.  Otherwise the rest of the accessories are like dessert – nice but unnecessary for the experience to be fulfilling and to satisfy your needs in an astronomy experience.

Anything that is going to foster a sense of learning in a child should be encouraged, and when your child is interested in astronomy, one of the things that you should think about buying them is a telescope. Here are three of the best telescopes that you can buy for your little astronomer.

Tasco 100x50mm Refractor Telescope

This telescope has a lot going for it – including a sturdy design and the fact that it’s ease to set up and use. For parents who are looking for the ideal first telescope for their child, they are going to find that this one is a great choice. Even though it’s principally designed for children to use, it’s crafted well and quite powerful.

One of the things that you are going to need when you are starting out in astronomy is a telescope. But there are a lot of different types of telescopes that you can choose from. here are some good tips for choosing the best telescope for you and for your needs. They will help you to buy the one that is going to give you the results that you want to have.

• If you are buying your very first telescope and you have a small budget, the telescope that you should buy is the Dobsonian reflector
• If you are interested in viewing mostly planets, then you should buy yourself a refractor.
• If you’re interested in looking at nebula, star clusters, and galaxies, you should buy the very best reflector that you will be able to afford – a Dobsonian.
• If you are concerned about weight and portability but you want a telescope that is good all around? Then your choice is going to be a telescope by Schmidt-Cassegrain.
• If money’s no object and you want quality, then you should buy one of the apochromatic refractors. This is also something that you should buy if you are very serious about doing astrophotography.

These are the things that you should remember when you are looking at different types of telescopes and trying to decide what you want to buy. You should remember these tips because they are going to help you choose the right telescope for what you want to do in astronomy.

It’s good to know that there are different types of telescopes and that they all do different things so that you don’t have to spend money for a telescope that does something that you are not interested in.

Astronomy is an interesting hobby but it also can be expensive. Being informed can help keep the cost down.

Astronomy is something that is a lot of fun to study and has captured the attention of many people for centuries. Here are some of the most interesting and fun facts about astronomy and the world ‘out there’.

• It’s believed by scientists that we can only see approximately 5% of the matter that is in the universe. The rest of the matter is made up of matter that’s invisible, which is known as Dark Matter, and a very mysterious energy form called Dark Energy.
• The neutron stars are so very dense that just one soup can full of them would have more than the Moon’s mass.
• There’s so much energy produced by the sun that each and every second its core releases as much as 100 billion of the nuclear bombs.
• Even though Galileo Galilei was credited incorrectly with inventing the telescope, the truth is that someone named Johannes Lippershey, a Dutch maker of eyeglasses, created it. In truth, Galileo was probably the first one who used it to look at the stars.
• Black holes are so very dense, and the gravity that they produce is so great, that light can’t even escape.
• It takes so long for the light from the distant galaxies and stars to reach Earth that we’re really seeing the objects like they appeared many many many years ago.  So as we gaze at the sky, in truth we’re looking into the past.
• A supernova produced the Crab Nebula back in 1054 A.D.  The Arab and Chinese astronomers back then noted that this explosion was so incredibly bright that it could be seen in the daytime and that the night sky was lit up for months.

These are some of the fun facts about astronomy that most people don’t know but a lot would find to be interesting.

Green vehicles include hybrid vehicles, vehicles running off of battery power, and hybrids that will plug into the grid to recharge. This category also includes the experimentation of using alternate forms of fuel such as hydrogen based fuels, algae based fuels, fossil fuels such as natural gas, ethanol, and renewable fuels made from soybeans and biomass. The continued study and research of the advancement of the technology required to make these vehicles and fuel sources will continue to be vital to the future of society. It is now time to take the next step and learn more about non-emission releasing fuels and how they work so that this technology can contribute to further advancements in the use of green vehicles. Understanding how this all works together will continue to pave the way for future vehicles as well as advancements in space exploration.

The study of green technology is becoming a more important scientific field. Green technology is an environmental science that’s focused on conserving natural resources and finding new ways to reduce the negative impacts that humans have on the environment. Many universities, companies, and foundations support scientific study into technological advances that will help to reduce harm to the environment. Courses focused on chemical engineering, environmental biology, and other fields related to green technology can be taken at brick and mortar schools or through online undergraduate programs. The more individuals who study these fields, the better!

As scientists continue to study and research green technology to gain a better understanding of how society can use green technology, it will also help with future space endeavors. Right now, energy is one of the main barriers to entering deeper parts of space. Having a better understanding of green technology and fossil fuels will eventually help create efficient technology for space exploration, making it more feasible and more affordable.

The planet Mercury was named after Mercury, who was the Roman god in charge of thievery, travel, and commerce.  It’s t he planet that’s closest to our sun and it’s the eighth in size.  The existence of Mercury was known since prior to the 3^rd century B.C.  It was given two names by the Greeks. Apollo first named it when it was a morning star and Hermes named it when it came out in the evening.

It has a really big iron core which is probably partially, if not completely, molten. The outer shell is made of silicate and is only approximately 500-600 km in thickness.  The atmosphere is very thin and it’s made of atoms which were blasted off the surface by solar wind. Because of the great heat, the atoms go into space quickly.  Therefore, the atmosphere of Mercury is always replenished.

It’s a planet of some extremes. The temperature varies go between 90K and 700K.  Interesting enough, Venus is hotter and fewer fluctuations.  It has an orbit that is quite eccentric – when it’s at perihelion it’s a mere 46 million KM from the son but when it’s at aphelion it’s 70 million.

The planet doesn’t have any known satellites or moons.

Mercury Statistics:

• Mean Radius: 2439.7 km
• Mass: 0.055 (as compared to Earth =1)
• Density: 5.43
• Gravity : 0.376
• Period of Orbit: 87.97 days on Earth
• Period of Rotation:58.65 days on Earth
• Orbit Semimajor Axis: 0.387 au
• Orbit Eccentricity: 0.206

This is the interesting information that people have discovered about the planet Mercury. As you can see, there are a lot of interesting things about the planet that you probably never knew.  It’s a planet that a lot of people have studied and that is why it’s favorite planet of a lot of people.

A favorite planet of many is the planet Venus. Here are some fun facts about Venus that you may find interesting and informative to remember when you are using your telescope to find it.

• It is the second planet that is found from our Sun. It orbits 108,200,000 km from our Sun. Its path takes it around the Sun and in between the planet Mercury and Earth.
• It’s the sixth biggest planet in our solar system – its diameter is 12,103.6 km and its mass is 4.869e24 kg.  It’s 95% the size of Earth.
• It’s been called the sister planet to Earth.  It’s close to our size, it’s density is similar as is the chemical composition, and it’s got a few craters, which means its age is similar.  This is why a lot of people used to think that it might have life on it, but this is something that’s been proven impossible however.
• People use to think that it was two bodies, called Eosphorus, which was the morning star, and Hesperus, evening star.
• On the surface of Venus, the atmospheric pressure is 90 atmospheres. It’s composed of the gas carbon dioxide. It’s obscured by cloud layers that are made of the gas sulfuric acid, which makes an incredible greenhouse affect which brings its temperature to more than 740K.
• The rotation of Venus is 243 days on earth and the orbit of Venus is 225 days. Its days are longer than the year and it rotates backwards, which means it spins in the direction that’s opposite to the orbit around our Sun.  if you were on Venus, you would think that the sun is rising in the planet’s west and setting in its east.

If you look for Venus when looking through a telescope, you’ll find that the facts above are going to run through your mind while you gaze at it.

Neptune, who was a Roman god, was named Poseidon by the Greeks, was known as the sea god.  The namesake planet for him is the planet that is eighth from our Sun and the fourth largest in diameter.  Its mass diameter is smaller than Uranus but the mass is bigger.

Like Uranus, scientists think that it has a core that’s rocky and that’s about the same as the Earth’s mass, and they believe it’s surrounded by an ocean that’s huge and that’s mixed with material that’s rocky. The atmosphere is for the most part helium and hydrogen with a little bit of methane.

It’s visible using binoculars when you know where you should look for it, but you need to have a big telescope if you want to see anything but a dot.  When you look at it through the telescope , it looks like a small disk that is green in color.

Like the other gaseous planets, it has rings, four of them. There are also 13 satellites that orbit it, 8 of which have names and five that don’t have names yet.

The satellites are the following:

• Naiad:     Distance – 48 km   Radius 29
• Thalassa: Distance – 50 km   Radius 40
• Despina:  Distance – 53 km   Radius 74
• Galatea:   Distance – 62 km   Radius 79
• Larissa:    Distance – 74  km   Radius 96
• Proteus:    Distance – 118  km Radius 209
• Triton:      Distance – 355  km  Radius 1350
• Nereid:      Distance – 5509 km Radius 170

Those who are familiar with Roman mythology are going to recognize a lot of these names.  For those who are interested in learning more about the planet Neptune, you are going to find that there’s a lot of information about this and the other planets in our solar system on the Internet and through books.    There is a lot of information about astronomy and the planets and stars for you to discover.

The planet Saturn was named for the agriculture god from Roman mythology, Saturn. It’s the sixth planet when they’re listed in the amount of distance from our sun and it’s the second biggest of the planets in our solar system. It’s normally thought about for the ring system that is has. The rings of Saturn were first spotted by Galileo with the help of one of the very first telescopes.

The ways that Galileo used telescopes was something that really helped astronomy as a science. He didn’t know that the rings were apart from the planet Saturn, so he said that they were handles.  It was in 1655 that Christian Huygens, a Dutch astronomer, correctly discerned the nature of Saturn’s rings.

Saturn’s atmosphere is made of 88% hydrogen, 11% helium, and very small amounts of ammonia, ammonia crystals, and methane.  It’s often thought to be a star when someone sees it without using binoculars or a telescope, it can be seen clearly when using the proper equipment.

There are 18 moons that are around Saturn and there are additionally 12 satellites that have been newly discovered and are yet unnamed.

Here are some of the statistics of Saturn:

• Mean Radius of 58232 km
• Mass of 95.2
• Density of 0.69
• Gravity of 1:16
• Period of Orbit of 29.46 years on Earth
• Period of Rotation of 0.436 days on Earth
• Orbit Semimajor axis of 9.53 au
• Orbit Eccentricity : 0.056

In cartoons, sometimes people are shown skating and doing things on the rings of Saturn. But this is impossible.  But even if the rings are just made of gas, they are still really neat to see and that is why a lot of people love the planet Saturn.   When someone is able to view Saturn through the use of their telescope, they will be able to see how beautiful it really is.

When you are first getting into astronomy, there are some things that you should do in order to help you to get started with learning the night sky. These are some of the best things that you can do in order to get started in this exciting new hobby.

• Read About It – The first thing that you should do is to read everything about it.  This is going to help you to learn everything that you want to know about astronomy and getting to know the sky up above.
• Find Other Beginners – The second thing that you want to do is to find other people who are new to astronomy. There are a lot of different sites and forums online that you can find people just like yourself who are new to astronomy and are just finding the new and exciting things about astronomy.
• Start With Naked Eye – The third thing that you should do is to start learning the sky with the naked eye. Look for the things that you can recognize, like Orion and the Big and Little Dippers.
• Go to Binoculars – The fourth thing that you should do is to buy yourself a good pair of binoculars.  This way if you find that it isn’t for you, you haven’t spent as much money as you would have on a telescope and you can use them for other things.

These are a few of the things that you should do when you are just getting into astronomy.  Astronomy is a lot of fun and it’s very interesting and exciting when you are able to see things that you wouldn’t see otherwise. Just remember that it takes time and it’s going to be something that you can enjoy for a years to come and share it with your whole family.

At times we don’t feel the gratitude we should. We struggle with obstacles that seem insurmountable. But no matter what the state of our lives or what is going on within us, we must always remember to be and stay grateful for all the wonderful things that we have received. If we actually look around and realize what we truly have, then we are open to new bounties to come our way. If we are negative and ungrateful for the things we already have, then we close ourselves off from what could come our way if we were open to them. With the coming of a new year, there are many reasons to feel grateful. From holiday decorations to the coming of the New Year,, which can have countless new opportunities, there are many things to be grateful for, both large and small.

One of the most important things we should be grateful for is the fact that our greatest gift is that we are alive and on this wonderful earth and for the people in our lives. On a more practical note, I am thankful that I was able to get the help I needed from paydayone.com when my financial crisis hit.

While the former may be the biggest building blocks of life, there are many small things that we should be grateful for regularly – things that give us joy and may be looked over from time to time. Here are a few things that I am grateful for. I am grateful for tea. Tea is one of the simple yet astounding pleasures in my life. I can produce calm and tranquility like no other and the scent of it purely makes me happy. I am grateful for fresh snow. There is nothing more beautiful or picturesque than trees glistening with bright, new snow. If you stop and look at the all the wonderful things in life, there is no doubt you will find something to be grateful for this year.

Light pollution is essentially misused or misdirected light that results from the misuse of exterior lighting products. Types of light pollution are sky glow, glare, and light trespassing. These types of light pollution are not only bothersome, but can cause serious health risks for humans and animals while also affecting the environment.

Sky glow is a type of light pollution that means light is entering the night sky and causing a glow over urban and suburban areas. This can cause many nocturnal animals to have nowhere to go during their prime time to hunt and eat. This of course means their numbers are dropping, but as they provide us with food and keep many smaller animals’ population under control we as humans are affected as well.

Another type of light pollution, glare, is the kind of light that shines dangerously into people’s eyes as they walk or drive by a home. This type of light can make it difficult for astronomers and everyday people to find star patterns in our night sky. We can no longer just glance up and find the milky way. It is much to hard with amount of light being projected into the night sky. Not only can we not see our constellations as clearly, we cannot drive safely or take walks at night, as there is constant light being projected into our eyes from all directions.

Light trespass is unwanted light shining into a neighbors property or home. This is especially important for people living in urban neighborhoods with houses being built closely together. Many homeowners buy fog or spot lights for their home as an attempt at crime prevention. Unfortunately, these types of lights are intrusive to neighbors and may light up their whole yard as well as yours. Some obnoxious lights may even light up the inside of the neighbor’s home, causing them to have to buy black out curtains to block the light.

Although the average amateur astronomer can have their pick of a variety of eyepieces, telescopes, and accessories in which to view the universe, most people do not purchase these items just because they cannot see the stars. Something called runaway light pollutions is taking much of the night sky away from us. Decades ago, people might remember a time when they could see the Milky Way as it crossed the sky. Many have not seen this in years. There are young people today that do not even know the joy of observing a truly dark sky.

Issues with Light Pollution

To fully understand the problems light pollution cause, one must first comprehend the full meaning of the term. Light pollutions are also classified as luminous pollution or photopollution, which is an obtrusive or excessive artificial light. The definition that the IDA also known as the International Dark-Sky Association gives to light pollution is any unfavorable effect that is caused by an artificial light, which may include light clutter, light trespass, glare, or sky glow, that decreases energy waste and visibility at night. Light pollutions are categorized in two different varieties; local and sky glow, or glare and line-of-sight. The orange glow that can bee seen rising above the horizons which is the united effect amongst hundreds, and maybe even thousands of light that shine on roadway, parking lots, buildings, is called a sky glow. This glow serves to wash out the sky and extinguish faint stars.

Whether the light pollution is line-of-sight or localized, it can occur anywhere, from the largest cities to the smallest rural towns. A simple night glare by itself, may not be able to fade the night sky at the same level that sky glow does, but it may be able to blind the observer to a faint starlight by getting into the corner of an individuals eye.

Is it advisable to modify the roof of your house to convert it into an astronomy observatory? Or should you opt for an observatory from scratch? Both options have their pros and cons. Modifying the roof of your house is a much simpler affair. Contrary to what most people believe, you do not always need the dome to have an astronomy observatory.

Rather, you need a gap in the roof that will help you place the telescope in such a manner that it is completely free of obstructions. The biggest advantage of having a dome is that you get a clear view of a wide expanse of the sky. However, if you are an amateur astronomy expert and if you are just beginning to take serious interest in this science, even a gap in your roof can help you set up your own amateur astronomy observatory.

On the other hand, going in for kits that will help you set up the observatory from scratch will help you treat this hobby like a formal task. Many persons set up an observatory in their bedroom or in their guestroom by making a hole in the roof. However, the fact that the observatory situated inside the house means that people never take the effort necessary to understand astronomy.

The end result is that the gap in the roof remains closed all the time and there is no point of having the telescope in the house. If you have sufficient space, you can set up the astronomy observatory in your garden. It need not be a very big affair.

You just need sufficient space to stand, sit and move around a bit and also place your telescope. If you make use of the right kit, you can set up the observatory on your own so that you can save costs on establishment expenses.

A black hole is a common concept in astronomy, but do you really know what it is? If not then here is a little insight into what a black home is. A black hole is a region of space. In this region of space there is nothing at all that can escape. Not even light can get through the black hole. So how does this happen? It’s actually the result of spacetime going through a process of deformation that can be caused, at it’s base level, by a really small and compact mass. There is even a point around the black hole that is an undetectable area which actually marks the point of no return. They call this return an event horizon.

They call it a black hole because black signifies the fact that while the hole takes in all the light that hits it, it will never reflect anything back. All it does is sit and exist as a perfect black mass. These black holes do emit radiation just like a body with a temperature. The temp decreases and the black hole and it makes it often difficult to view the black mass. The only way to really view the black mass is if the black hole interacts with other matter.

One way that a black hole can be tracked is by watching a cluster of stars and the way they move in their orbit. You can see only if the black hole is interacting with the grouping of stars. Otherwise the black hole would not be visible to you. The only other time you can see a black hole is when gas falls into it. There the gas will heat to a high temperature and will omit radiation and that radiation can be detected from telescopes. A black hole is simply fascinating.

Understanding a supernova and what it does is key to learning the basics of astronomy. The supernova is, in effect, an explosion that is has more energy in it than a regular nova. The supernova is very luminous and that radiation that it can give off is enough to make a second or two where it will shine so bright it will literally outshine the galaxy. Once it is done shining it will go back into hiding and it won’t be seen from again for a few weeks or up to a few months. The energy of a supernova is intense. Just one burst of a supernova and it can radiate an amount of energy that is equivalent to what the Sun can generate throughout its entire lifespan.

When the explosion happens the star expels all of its material. This will put a shock wave into the surrounding medium of interstellar happening. There is more than just one type of supernova. There is a type 1 and type 2. These two types can be triggered in two different ways. There is the first where you allow nuclear fusion to be the catalyst to trigger it by generating energy. This will expel the stars layers out creating the blast. The other way is through something called a white dwarf star. Here, this will happen because the stellar companion can raise the temperature so that you can ignite carbon fusion.

The truth is that it’s been a long time since the supernova has been observed. The last time on record was the Milky Way and it happened in 1604. Now, even though these supernovas occur once every 50 years, it’s not always visible from earth. The Supernova is just one of the many fascinating things about the universe in which you live in. It’s just one in a long line.

Learning about the supernova is important to understand all the we now know about it. The earliest recorded supernova was in 185 AD. Then it was observed by the Chinese Astronomers. They weren’t sure what it was at the time but documented the occurrence. Only years later did they learn that it was, in fact, a supernova. The brightest recorded supernova was in 1006. It was, once again, noted by Chinese astronomers. Since that time there have only been three more supernovas with the last being the one spotted in the Milky Way Galaxy in 1604. The last two of the supernovas had a very profound effect on the development of astronomy in Europe. They were able to use it in order to prove that the universe did function beyond the start and the moon and the planets.

One of the biggest advancements for supernovas and beyond was the making and improving upon the telescope. In 1885 the observation of the supernovas in other galaxies were important. These supernovas are not just an interesting thing to see. As a matter of fact they are an important tool in the world of astronomy. They are important in measuring the distances out there in outer space. They used the supernovas in the science lab too. They took the supernovas and built models from them. By doing this they were not only able to get an accurate replica of what it did but also how it helped other interpret the information they were seeing, such as how the distances were between two objects.

The role of the supernova is a big step in learning more about the universe. Seeing a supernova is just one of the many occurrences that led people to believe that there needed to be the exploration of space. Our knowledge of these supernovas grow and the result is a better understanding of the history of our universe.

There is physical pollution, air pollution and even noise pollution. However many people do not realize that there is a thing known as light pollution. Although light pollution is all around the world and right next to a person, many people do not know about it or the harmful effects that it can have on the environment.

Light pollution is the term given to extreme artificial light that obstructs the night sky from any of the various areas. Light pollution is sometimes referred to as luminous pollution or photopollution.

Light pollution is usually caused by extreme artificial light, mostly from larger cities. These lights can come off of the surrounding buildings, advertisements and street lights. Anything that outwardly displays artificial light can be taken as light pollution in some way or shape.

The effects of light pollution can be extreme. The main effect that it has it that on the night sky. Most light pollution obstructs people’s view of the night sky and stars and prevents them from seeing the night sky naturally. In fact, in a recent study of the United States National Parks, it observed that every single national park in the United States is effected by some form of light pollution.

Another less obvious effect that light pollution has is that on the surrounding environment. Like the various other pollutions, light pollution can have major effects on the surrounding environment and ecosystems. For example, bats who are extremely light sensitive can often have problems with time and light if they are near a population that has extreme light pollution.

Some societies and governments have slowly started to address the issue of light pollution. In an effort to combat the amount of light pollution cities are implementing a strict curfew for large signs and building lights in an effort to try and reduce the amount of light that is visible in the environment.

Education about light pollutions is very important because it can help in the reduction of complications that occur because of the light pollution. There have been many people who have been affected by the light pollution, but they have not surfaced and become a issue because they are few in number. Compared to the other kinds of pollutions and the diseases that they cause, the problems caused by light pollution are not life threatening.

There are some common problems that occur in people who suffer from light pollution. The major problem is related with the eye. Increased strain to the eyes can lead to problems in the eye later in life. Other than the eye defects that are possible, there could be some permanent damage to the eyes too. In some rare cases, blindness can occur because of repeated stress to the eye over a period of many years.

The other problem that is common is that the person who is exposed to continuous light will suffer from confusion. The biological clock is programmed and the normal person will go to sleep as it becomes dark. The presence of light at all times makes it very difficult for the body to identify the normal rhythm and it is lost. This causes the person to have abnormal sleep. The decreased sleep because of the exposure to light can cause various chronic diseases like increased blood pressure and other severe complications like depression.

Adequate education about light pollutions can help the general public to learn the need to reduce light pollution. This will help to decrease the complications including health problems that occur due to the excessive exposure to light. Just like the other pollutions like noise, air and water pollutions, the light pollutions also need to be adequately controlled. This will help in preventing complications due to light pollution.

In the wonderful world of astronomy there is a beautiful event called the supernova. What is this large, bright burst of light? What does it do in the system? How is it named?

Let’s explore a little bit about the supernova and what makes this type of universe phenomena so amazing.

A supernova is a huge explosion that happens out in the universe. It is extremely bright. So bright that it actually outshines the whole solar system that it occurs in. When a star or planet has such a burst of radiation it shines brightly in the universe, as described above then quickly fades away until nothing.

The occurrence of the supernova occurs for one of two reasons. Either there is combination of nuclear fusion that causes the energy to be quickly turned on or in some cases turned off. The energy shines out brightly and quickly the core of the star or planet that showed this type of energy, folds into itself and quickly disappears from the universe.

There hasn’t been an occurrence of a supernova in the Milky Way, the solar system that Earth is in since 1607. However a supernova occurs about every 50 years in other solar systems and universes that surround the Milky Way.

The naming of a supernova is a fairly unique process. When a supernova occurs a notice gets sent out by the International Astronomical Union. In it it contains the name that is being officially assigned to the supernova that occurs. The way the name is made is that it has the year the supernova occurred in and an assigned one or two letter abbreviation. The first supernova to occur during the year is assigned the letter A all the way through Z. Once it reaches the letter Z it starts over with two lower case letters such as aa. There has never been a need to go beyond two letters.

Have you ever noticed that it’s rarely dark at night? Maybe youâ I’ve walked to your car after eating at a restaurant, or been driving down a deserted road at night, when you noticed the phenomenon. Not owing to the moon;s brilliance, the night is filled with light, and stars seem harder to see than in the past. It’s happening everywhere in the world, although America is near the forefront of the issue. The brightness at night is called light pollution, and it’s just another byproduct of human existence.

While most people are aware of the long lasting, detrimental effects of discarded plastic shopping bags, rechargeable batteries, and nuclear sludge from nuclear power plants, many are unacquainted with a non-physical pollution. Sure, even auto emissions have some sort of dirty, measurable quantity to them, and nearly anyone can picture a ton of carbon dioxide, particularly after witnessing a large truck with a bad exhaust pipe let loose a huge cloud of black smoke. But light pollution is less identifiable as a pollution, because it seems to emit nothing harmful. However light does create pollution, in two ways.

One is the obvious brightening of the night sky. Over 90% of America is now affected by light pollution, meaning that in only 10% of the country’s real estate, can one gaze upwards at night and truly drink in an unspoiled view of the surrounding galaxies. Even deep in the mountains outside of Denver, or Salt Lake City, light from these metropolitan centers bleeds into the view many miles away. It’s worse where there aren’t mountains to block the direct lights.

The other sort of light pollution is less obvious, but becomes more so by tracing the power source. Each lightbulb requires energy, and that energy comes from a power plant. Most power plants burn coal to make power. This creates emissions, but occurs far away from the light switch. That’s something to remember when next you’re gazing at the stars.

Light pollution is excessive light from artificial sources. If such light is obstructive in nature, then this situation is called light pollution. One of the problems in the environment that we are facing is light pollution. When you were driving on a busy highway, did you dilate your eye to get a better view of the road? If you have pondered why this happened, then you are facing a situation called light pollution. This is a case of ineffective outdoor lighting that is hazardous for commuters on the road. Most of the accidents at night happen because people did not see something they should have seen.

When too much artificial light is present in the surroundings, it causes visibility problems. It also causes a waste of energy. Human health undergoes a lot of changes because of altered light sources that are different from natural light sources. Natural light is the best thing for humans to have. It is natural light that provides photo-nutrition for life on Earth. And even human beings need natural light.

Light pollution is a serious issue, with a solution wanting to happen. People have begun to take cognizance of this issue. Light pollution is said to cause disruption to star-light coming to Earth. It also causes poor performance of astronomical observatories. Just like other types of pollution, it causes health problems for human beings.

Light pollution is a result of the industrial growth of the human civilization. You can see light pollution everywhere. Illuminated billboards, glaring motel lights, offices with lit floors, and in many more manifestations. In heavily industrialized areas, light pollution is more significant by its presence.

Light pollution does not do well for energy conservation. It wastes a lot of energy with unwanted illumination. Light pollution can also be intrusive in nature. Many people would have experienced how an artificial light source of another building trespassed into their living or working areas. This annoying condition is called light trespass.

Astronomy is the study of objects in outer space. It should not be confused with astrology. Often people tend to get confused between astronomy and astrology. But these two are different even if there are some common connections. Astrology does use the concept of the movements of celestial bodies for its astrological calculations.
Astronomy runs back into ancient times, as a science studied by prehistoric people. The Egyptian monuments are one such relic that identifies the advancements made during that time in astronomy. Indians, Greeks, and Babylonians were the pioneers in astronomy. A lot of inventions and discoveries in astronomy can be found in all these countries.

During those times, the sky at night was extensively studied from astronomical observatories. In the modern era, the telescope has been one instrument that has helped the cause of astronomy. What was observed using naked eyes is now observed using telescopes.

By the twentieth century, astronomy evolved to become a subject with theoretical and observational applications. Observational astronomy is the foundation of theoretical astronomy. What was observed was brought to the table and analyzed using laws of physics in the Universe.

More than professional astronomers, amateurs contribute to the growth of astronomy. Some of the things that are happening in the sky can’t always be monitored by professional observatories on Earth. This is where amateurs pitch in.

Another version of astronomy called radio astronomy deals with the studying of wavelengths. Radio waves are studied for their frequency, amplitude and a lot of other properties. Radio waves coming from space are captured and studied by physicists. The space has a lot of magnetic flux that could cause the discharge of radio waves. The resultant radio waves act as a basis to understand the source of the radiation and in general the event that is happening in some part of the Universe.

Recently, 2009 was declared as the year of astronomy. The International Astronomical Union is stepping up efforts to improve the field of astronomy.

Hollywood movies have have been made about the black holes that exist in the universe. Star Trek has taken us to the event horizon and back again. Black Holes are the subject of science fiction. Carl Sagan presented them as an entrance to another world where societies in the galaxy use them as a transit system. The stories created around these mysterious areas in our world and worlds beyond are only limited by our own imaginations. The facts that are known about black holes are as fascinating as the fiction presented to us.

Science presents us with the facts about black holes determined by years of study. Massive stars ten to fifteen times the size of the sun that have reached the endpoint of their existence are the perfect candidates to become a black hole. The types of black holes identified include the Stellar which is formed from a star, the Super-massive which are identified as those black holes at the center of a galaxy and the Miniature which are capable of evaporation. Steven Hawking’s study of black holes in the 1970s indicated that particles and light are created and destroyed during the evolutionary process of the black hole. This process creates a glow at the area of the event horizon. Over a very long period of time the mass of the black hole eventually evaporates.

The creation of a black hole is a result of the death of a massive star. The process is a result of a mass thousands of miles in diameter shrinking to just a few miles in diameter. At the pull of gravity the dense form of the star disappears inside itself. Nothing escapes at this point, not even light. The event horizon of the black hole is an area of no return. Identification of black holes are made by observing gaseous matter from nearby stars that enter the event horizon and forever become a part of the black hole.

In the world of astronomy a lot of words get thrown around. There are many words, terms, and happenings that we are all unfamiliar about. One such term is solar flare. It’s a word that you have heard a million times over but might not actually know what it is. Well, a solar flare is a larger explosion that occurs in the suns atmosphere. This explosion is so powerful it can release up to 6 x 10 joules of energy. When referring to the same type of happenings, but when it happens to a star it’s called a stellar flare.

The interesting thing about solar flares is that they can affect every single layer of the atmosphere. They can, when in the midst of a solar flare, heat plasma can rise to well over ten million degrees. The flares will occur in the regions that are active around the sunspots where the intense magnetic field that can penetrate through the photosphere and get to the solar interior. These flares are given their powered the release of magnetic energy that is stored in the corona. This release can be sudden. There can be a coronal mass injections.

X-Rays and radition that are released by solar flares have a direct effect on the Earth and it’s ionosphere. One of the ways we can see the effects of these solar flares is that they can disrupt long range radio communications. These direct radio emissions at decimetric wavelengths will disturb the radars and other devices operating these frequencies. Flares were first observed by Richard Christopher Carrington and also by Richard Hodgson although these observations were done independent of each other. Solar flares were also observed by observing a variety of other stars. Solar flares are some of the most fascinating occurrences in the solar system and scientists and astronomers will continue to research them for years to come.

There are as many reasons to visit an astronomy observatory as there are stars in the sky and each reason is as individual as the person who visits one.

Sometimes teenagers get wrapped up in their own lives that they forget that they are one small part of a giant universe. A family with teenagers may choose to visit an astronomy observatory so that the teens can see for themselves that the world literally does not revolve around them. Perhaps it can help the teen put their daily problems into perspective.

There has been a lot of talk that the world is going to end on December 12, 2012. If someone would like to check the stars to see for themselves if the Mayan Calendar is right after all, an astronomy observatory is the place to find out.

People who are visiting Rome and would like to have a spiritual experience while viewing the stars may find the Vatican Astronomy Observatory is just the place for them. The observatory is near the Pope and the stars at the same time and in the middle of the breathtaking Italian countryside.

There are many myths surrounding the secrets of the sky. An astronomy observatory can help someone understand why the moon looks like a fingernail at certain times of the month and if it is really made out of green cheese.

When a child shows a budding interest in science, they can taken to the nearest astronomy observatory. While they may not choose to become an astronomer, the wonders they see out there in space may spur their imagination and encourage them to wander outside to see what other wonders nature has to offer them. Viewing the beauty of a supernova or solar flare will bring out the best in people of all ages.

Astronomers world wide celebrated the 400th anniversary of the very first observations made using a telescope, by Galileo Galilei, by declaring 2009 to be an International Year of Astronomy. Organized by the International Union of Astronomy (the IUA), this event was intended to educate the citizens of earth about the fantastic cultural contributions that the science of astronomy has made over the last four centuries.

Collaborative committees comprised of professional and amateur astronomers were formed to manage most of the IUA events, called “sidewalk astronomy events,” which took place at planetariums and public Observatories across the globe. Individuals could also contribute privately, assessing for themselves where the need was greatest. However, the most successful element of the IYA was probably the eleven so called, “Cornerstone projects.”

One of these projects, called “Dark Skies Awareness,” was to measure, and to provide education about, light pollution. This project was broken up into three separate programs (GLOBE at night, the Great World Wide Star Count, and How Many Stars) that all did essentially the same thing, though at different times during the year. These programs provided people first hand experience dealing with light pollution through “star hunts” or “star counts.”

A year later, in 2010, it seems clear that all the effort that was expended to create fun and accessible projects has not been wasted. Knowing that the science of astronomy is one of the few sciences that amateurs can make a significant contribution to has inspired some ambitious amateurs to make important advances in astrophotography. Perhaps because of this new interest and these amateur contributions some fantastic new websites about the science of astronomy, such as such as this one, show that the public’s interest has been peaked.

It looks like the International Year of Astronomy was a resounding success.

As we wake in the morning, we know we have to get up and get moving because the sun has come out. It has signaled us that the day has begun. The sun keeps us warm and guides us through our day. But what happens when the sun’s day is done? We are bathed in the warm glow of the moonlight. Sometimes hidden, sometimes visible, what is all around the moonlight, is our solar system, busily keeping its rhythm within the universe. The science of Astronomy is the study of the stars and planets. This is a fascinating study. Just think, there are millions, maybe even trillions of stars and planets in the sky, just waiting for us to glance up and recognize them.

Our sky becomes the solar system’s playground at night, from the supernovas, stars that are much larger than the sun which run out of fuel and explode in the sky, to the solar flares, the release of magnetic energy that has built up in the atmosphere. At any given time our solar system can be a veritable fireworks display. But there are those times, the times astronomers the world over wait weeks, months, sometimes even years for, when we get to witness amazing occurences in our world, such as solar eclipses,lunar eclipses, planets moving around, even an asteroid or two flying through the air.

As all of these natural occurrences are flying around us, we too, have a responsibility to our solar system. The excessive use of electricity and artificial light has created “light pollution”, which is, according to the McGraw Hill Science Technical Dictionary, “the alteration of the natural quantity of light in the night environment due to the introduction of artificial light.” Astronomers warn us that we need to be careful, so that this carnival of a light show will be visible for generations to come.

Light pollution is essentially misused or misdirected light that results from the misuse of exterior lighting products. Types of light pollution are sky glow, glare, and light trespassing. These types of light pollution are not only bothersome, but can cause serious health risks for humans and animals while also affecting the environment.

Sky glow is a type of light pollution that means light is entering the night sky and causing a glow over urban and suburban areas. This can cause many nocturnal animals to have nowhere to go during their prime time to hunt and eat. This of course means their numbers are dropping, but as they provide us with food and keep many smaller animals’ population under control we as humans are affected as well.

Another type of light pollution, glare, is the kind of light that shines dangerously into people’s eyes as they walk or drive by a home. This type of light can make it difficult for astronomers and everyday people to find star patterns in our night sky. We can no longer just glance up and find the milky way. It is much to hard with amount of light being projected into the night sky. Not only can we not see our constellations as clearly, we cannot drive safely or take walks at night, as there is constant light being projected into our eyes from all directions.

Light trespass is unwanted light shining into a neighbors property or home. This is especially important for people living in urban neighborhoods with houses being built closely together. Many homeowners buy fog or spot lights for their home as an attempt at crime prevention. Unfortunately, these types of lights are intrusive to neighbors and may light up their whole yard as well as yours. Some obnoxious lights may even light up the inside of the neighbor’s home, causing them to have to buy black out curtains to block the light.

Light pollution is excessive light from artificial sources. If such light is obstructive in nature, then this situation is called light pollution. One of the problems in the environment that we are facing is light pollution. When you were driving on a busy highway, did you dilate your eye to get a better view of the road? If you have pondered why this happened, then you are facing a situation called light pollution. This is a case of ineffective outdoor lighting that is hazardous for commuters on the road. Most of the accidents at night happen because people did not see something they should have seen.

When too much artificial light is present in the surroundings, it causes visibility problems. It also causes a waste of energy. Human health undergoes a lot of changes because of altered light sources that are different from natural light sources. Natural light is the best thing for humans to have. It is natural light that provides photo-nutrition for life on Earth. And even human beings need natural light.

Light pollution is a serious issue, with a solution wanting to happen. People have begun to take cognizance of this issue. Light pollution is said to cause disruption to star-light coming to Earth. It also causes poor performance of astronomical observatories. Just like other types of pollution, it causes health problems for human beings.

Light pollution is a result of the industrial growth of the human civilization. You can see light pollution everywhere. Illuminated billboards, glaring motel lights, offices with lit floors, and in many more manifestations. In heavily industrialized areas, light pollution is more significant by its presence.

Light pollution does not do well for energy conservation. It wastes a lot of energy with unwanted illumination. Light pollution can also be intrusive in nature. Many people would have experienced how an artificial light source of another building trespassed into their living or working areas. This annoying condition is called light trespass.

Since man first roamed the Earth, people looked toward the skies with curiosity. Modern day man has a powerful tool to observe outer space, the astronomy observatory. Several such observatories exist throughout the world, including many in the United States.
From these observatories, events like supernovas, black holes and solar flares are observed and recorded. Scientists can compare what they see with researchers working in observatories across the globe to better understand these space phenomena.
Astronomy observatories are located in the countryside with some of the most powerful observatories located in remote areas because of light pollution. Lights from households and businesses make viewing outer space more difficult so scientists find education about light pollutions important in observatory areas. The observatories are also often built in places with many clear nights each year so that the scientists can work more days out of the year. They’re also often built at higher elevations because the Earth’s atmosphere is thinner and astronomers don’t have to to deal with as much atmospheric turbulence at higher elevations.
Most astronomy observatories include a dome that’s often retractable to protect the powerful viewing microscopes from the elements. Often the portion of the dome that’s retractable is only a small slit. The dome rotates around to allow scientists to focus on any part of the night sky.
Humans have been using observatories for years. The oldest recorded observatory was in use around 150 BC in Greece.
According to experts, a ridge on Antarctica today is the best place for an observatory because of clear weather and the least amount of atmospheric interruption.
In the United States, Hawaii and the Southwestern United States are considered good viewing areas with observatories located in both locations. Observatories are also often located on college campuses for students enrolled in astronomy classes to view space events.

What is light pollution? How can excess light cause problems? Well, balance is very important in nature. That is a reason why we have days and nights. For every 11 to12 hours of sunlight, we have another 12 to13 hours of darkness as well. The same is true for seasons as well.

If you have three months of summer in your region, you also have three months of monsoon, spring and winter to balance the entire cycle of nature. In such a scenario, excessive use of lights by human beings will obviously spoil this balance.

We often presume that light pollution is something that affects birds and other animals only. That is not the case. Light pollution affects human beings as well. Being exposed to artificial light all the time causes problems in internal activities of the body. Natural sunlight is not just an option. Rather, it is a compulsion for our body. If we ignore this, we obviously are going to face problems.

Secondly, being exposed to harsh light all the time places strain our eyes and the nervous system. If you feel that this is an exaggeration, just take a look at all those individuals who put in a lot of time and effort under artificial lighting.

Excessive light in urban centers during night confuses birds and affects their body clock. Ideally speaking, human beings should sleep early and get up early. The morning hours are the most productive for our mind and body. However, we often end up spending more time staying up.

Installing dimmers in your house will help even if you cannot switch off the lights. One ancillary advantage of this approach is that you can have a romantic dinner with your spouse by simply dimming the lights to set up a candlelight atmosphere. Not only will you be helping the environment, you will also enjoy a good time with your spouse.
