Today, much is being said about space. There is even talk of making the next space tourist. When the first private space shuttle has been tested in Russia and very soon travel can be realized.

when space has been explored much, astronomers and scientists. Many manned and unmanned space missions have been conducted by different countries. Scientists are looking for new ways to explore space, to help us understand what lies beyond.

However, while there are advocates of space exploration, there are also critics. So, one has to weigh the pros and cons before advancing space exploration.

One of the biggest benefits of space exploration is being able to discover unknown facts about space. The universe is a mysterious place, and by conducting research space, many of the mysteries can be answered. A survey will also help mankind to discover new mineral and precious metals. It is quite possible that in one of the studies to find an alien race similar to humans. Maybe we’re not alone in this immense universe. Pollution plays havoc with the planet, space exploration can help us to find another planet that we can create if Earth becomes unlivable. Thrill to try something new and different can spur sense the number of people of adventures. So, space exploration has the potential to satisfy this need.

On the other hand, the money spent on research and subsequent research is enormous. If this money was used to help underdeveloped country could have brought joy and a better way of life for millions. The national wealth is used for space exploration and research, and if the same money was used to help the down and out in the community, it would have been better spent. Also manned spaceships sent to space risk life astronauts. Many astronauts have been killed when their spaceships exploded while returning to Earth. It is quite possible that maybe harmful microorganisms in space that could be fatal to humans. So, the risk is always present in one of the manned or unmanned space missions, these microbes can find the way to the ground.

The majority of astronomers consider investing in their equipment such as binoculars and connect computer systems etc. However, those who want to take their profession to the extent that is most familiar with “need” to invest in buying or hiring an excellent and efficient workplace too. Having highly relevant work is more important than having good equipment. As the weather changes are not foreseeable and is personally Observatory dome assures viewers that they have more chance / time to carry out their work on time. Carrying equipment and large telescopes position is no longer needed astronomers since backyard observatory funds for sale have resolved the issue to a great extent.

What is the Dome?

hemispherical-shaped enclosures that are commonly known as backyard observatory funds consist of equipment used by both physical or other (unearthly) events. There are several vendors offering virtually indestructible, maintenance free and incredibly affordable Observatory capital for sale. These backyard observatory financial provide users shelter from the weather, wind, light wind storms, rain or even hail and also from annoying voices or noise coming from the respective district. Sitting inside the observatory dome is the experience worth the nominal price you pay to buy the dome of their own.

What these financial houses are made of?

Mainly UV stabilized ie very strong polyethylene plastic used in the observatory funds, however, other materials such as steel, aluminum and fiberglass are also used. Usually, there is an upper door that runs open. The shutter door on the lower side of the specific financial flips out instead. There are certain companies that have come up with several changes rather innovative design and features so that Ocean Observatory financial incredibly affordable for everyone. Typically, funds not very heavy to lift or move. They may be around 200 pounds in weight.

While getting ready to take the astrological pictures or images, set up the equipment in question these may require a lot of effort and time for astronomers. A larger telescope, for example, may require more time to be lined up and sees that the acceptable polar compared to relevantly smaller equipment. Meantime, the weather conditions have changed to make “efforts” useless because precious time consumed in installing the equipment. This would simply leave the viewer frustrated because he found it difficult to connect telescopes or other equipment to computer systems and during the process alive through places were changed. Therefore, it will be terribly important to the process of building the observatory is as simple as possible

appropriate action :.

To address the above noted problems and some other items, it should be permanent and mobile ‘arrangement’ or multipurpose solution.

• All dome house will be able contains all the necessary tools so the issue is no longer to leave the valuable telescope or computers in a separate room or building their homes.

• Backyard capital to sales or field funds shall give inspectors with maximum facilities within limited space for recording of events on the subject in a moment.

• Both types of available funds namely Pro dome and Home Dome must also make certain materials to protect both. The Observer and his equipment from the weather ‘ unwanted ‘intruders.

• Financial should also match viewers’ desired Astronomy information and environmental.

• They must also be easy to install with minimal effort and as fast as possible.

Study of telescope makes for interesting reading. In 1722, John Hadley, an English mathematician, completed form reflector telescope for the style of Newton as a mirror obviously figured appropriately. This device attracted a lot of attention, and now other parties were to turn out Newtonian reflector, the following technologies Hadley, which consisted of removing spherical aberration as it was revealed by extra-focal diffraction rings and star formation.

Hadley then turned their attention to the design of James Gregory and in 1726 he produced the instrument slightly over 2 “in diameter and 12” in the focal length. This proved so successful that construction was in the hands of others.

Notable among them was James Short, who made both Newtonian and Gregorian in great numbers, from about 1732 until his death in 1768 he bought Observatories larger instruments, a tribute to his skill and the smaller ones were launched mainly among the nobility and amateur astronomers.

main attraction Gregorian design was upright image it gave, which made it suitable for terrestrial use. This situation affects their choice of Newton, despite his pictures must have been pretty bad. Far into the 19th century, though the Gregorian riding the wave of popularity that no type of telescope has known, where surprises in relatively recent years with the flood enthusiasts who flocked to design Newtons.

From the time of the invention of the telescope, and startling discoveries moons of Jupiter and the rings of Saturn, the interest in astronomy had become something contagious. Each new discovery was awarded the widest coverage, stimulate desire in them to learn to get first-hand insight of these celestial wonders. It was not possible even for the average person to make his own speculum, but many contrived to fit optical lenses in a tube, much as Galileo had made some 150 years before. This really was one of the first on the first telescopes.

Those means permitted bought a telescope, and envied the gentleman who was one of three or four inches aperture, with “exclusive” artist. But, judged by modern standards, many of them were reflecting slightly. There is one (manufacturer unknown) in Fugger Collection of Augsburg, barely 1 “in diameter and 6” in the focal length, which was concealed in a walking stick! Eyepiece lenses of 1/6 “or less focal were very common.

The metal used in this first mirrors the alloy of copper and tin, the usual rate of 75 to 25, could be given a beautiful polish. But metal was very hard work, and a prodigious amount of labor involved in the grinding and polishing process. To facilitate the work, relatively thin disc was thrown to the intended track, backs also be bent to give uniform thickness and constant temperature effect Mala was made . the convex iron tools similar radius, with Emery, and sometimes sand. Polishing was done on the pitch circle with rouge.

Manufacturers devised usually their own machines to work grinding and polishing. Except in very perfection was important, speculation seems to have consisted largely of the final brief variant of stroke, in unguided try to focus on polishing center. Critical examination, probably rarely indulged in for its laboriousness, could still only be performed on the star. The reflective ability, speculum was only about 60 percent efficient, and surface tarnished quickly, made a rather serious light loss. This often means repolishing and repolishing meant refiguring.

It is interesting to inquire into the prices that were asked telescopes during this period, in the late 18th century. Below are the prices and sizes of some of the Gregorian made by Short, chosen from his store. Newtonian similar sizes were priced only slightly lower.

 Diameter (inch) focal length (inches) Expansion Price (guineas) *

 1.1 3 18 3

 1.9 7 40 6

 4.5 24 90-300 35

 6.3 36100-400 75

 18,144,300 to 1.200 800 

* An Enska gold coins, issued for 1813, equivalent to 21 shillings, or about five dollars.

The earliest telescopes were certainly gaining popularity by this time.

When we look to the stars, we think of the unknown and the future, but more than any other science, astronomy is deeply rooted in the past. From Stonehenge to Galileo to Hubble following article details the history of astronomy

Stonehenge

Egyptians, Mayans, and Chinese were all avid observers of the heavens. Perhaps the most known example in the history of Stonehenge was built by Neolithic people of Britain moves the sun. Stonehenge was important for religious reasons, but people also believed Celebrities could help lead their lives and foretell events. This was true in a very practical sense, accurately predict the seasons helped farmers plan crop season. The stars were also accompanied on the horizon, sailors used to navigate trips.

Around the World

Astronomy was one of the first branches of knowledge to rely on mathematics. In 256 BC Greek mathematician Eratosthenes calculated the circumference of the earth with the horns of the shadows cast sun. About 140 CE Ptolemy, another Greek thinker, advanced “geocentric” universe with the Sun orbit the Earth.

The Telescope

Although Arab astronomers and astrologers make progress in the next few centuries, modern astronomy began with the invention of the telescope by Dutch lens maker Hans Lippershey in 1608. The next year Galileo Galilei used a telescope and discovered craters on the moon and the four large moons of Jupiter. Early telescopes were limited due to their glass lenses tend to distort images. Isaac Newton solved this problem in 1668 by inventing the reflecting telescope, using mirrors instead of lenses. A string of discoveries followed, including the discovery of two new planets, Uranus (1781) and Neptune (11 845).

Golden Age of Astronomy

The twentieth century was the Golden Age of astronomy. In 1801, the discovery of the first asteroid, Ceres, started a flood of new objects in the sky that astronomers working with the tools have grown in variety and sophistication. 1937 Grote Reber built the first radio telescope. Technological advances made possible large telescopes like the Mount Palomar has a 200-inch mirror.

The Hubble telescope

Today astronomers have even more exciting tools. The best known is Hubble, put into orbit by space shuttle Discovery in 1990. Amazingly, Hubble is still based on the original reflecting telescope Newton! Yet it and other space-based tools are so powerful that they have discovered more than 200 planets orbiting other stars.

Amateur Astronomy

Astronomy is unusual because enthusiasts remain an important part of the search for new knowledge, discover supernovas, comets, and other objects. For example, the famous Shoemaker-Levy comet that struck Jupiter in 1994 was co-discovered by amateur David H. Levy and it is only one of 22 comets he has found!

The future of astronomy is as bright as the stars astronomers observe and for the rest of us as well. It is one of the few areas where foreign experts can actively participate in the search for human knowledge.

As you already know, the telescope is a device used to make far objects appear closer. But how telescopes work? Well, there are several types of telescopes, but they generally work the same way.

How telescopes work?

Light is collected from a distant object (like a star) through the objective lens (used in Refrigeration Actor meters) or primary mirror (used in reflector scopes). The light then travels through the body to the eyepiece, which is similar to a small magnifying glass, increasing the size of the image!

Who invented the device?

Despite what many think, the telescope was not invented by Galileo. Although there has been much controversy, Hans Lipperhsey has been given credit for the invention, as he was the first to patent the device in 1608. Galileo realized the potential of tools for astronomy; many great discoveries were made soon after.

buy Telescope

There are many factors to consider before buying a telescope. The most important aspect of the device is the diameter of the objective lens (or primary mirror), which determines the amount of light that enters the scope body. More light = larger and more detailed image. So the larger objective lens (or primary mirror) the better!

The eyepiece also plays an important role in producing good image. If the lens is low quality, then the amount of light entering the scope is going to destroy! Good lenses need to enlarge the image accurately and without distortion.

Costs can be the deciding factor, as everyone knows, good technology is not cheap! Fortunately, you can get a really good telescope for less than a hundred bucks. Many of the low cost ones will be perfectly sufficient for watching detailed images of the craters of the moon, Jupiter and even the rings of Saturn!

The invention of the telescope was a major improvement in the science of astronomy, but who invented it? Maybe you think you already know the answer.

Well, what would you say if I told you that you’re probably wrong? After all, it was Galileo Galilei who invented it, right? You might be surprised at the answer to that question. Although Galileo Galilei was a great astronomer, he did not find the telescope.

If not Galileo, then who?

man named Hans Lipperhey invented the telescope. He was born in Wesel, Germany and made his home in Middleburg, part of the Zeeland province in the Netherlands. He was married there in 1594, and became a citizen in 1602. He was a spectacle-maker by trade.

Italians developed new glass-making technique was introduced to the Netherlands in 1590. These new methods help to bring new ideas and innovations in glass-making community and people began to experiment with different ways to combine lenses.

Where is the proof?

Many others say they have found a telescope, but Hans Lipperhey is the only person documented to have applied for a patent for the device.

children game

Legend has it that it was not his own, but his children who actually invented the telescope while they were playing.

So now you know the story of the telescope and how it came to be.

The outer planets of the solar system, after consideration, help us to really understand the sheer size of not only our own system, but the whole Universe. There are four outer planets in our solar system. They are as follows :. Jupiter, Saturn, Uranus and Neptune

Jupiter

As we venture out past Mars and the asteroid belt, we find the fifth and largest planet in our solar system, Jupiter. The largest planet in our solar system, Jupiter is so large that more than 1,000 Earths could fit inside it. Jupiter comes as close as 365 million miles away from Earth at the closest point of its orbit. That’s more than the distance from Mercury to Earth, Venus to Earth, and Mars to Earth together! Its distance from the sun is even more remarkable: 460 million miles on its second and 508 million miles at the farthest point of its orbit. It takes Jupiter 12 Earth years to orbit the sun and spins on its axis once every 9.8 hours. This means that Jupiter is spinning very fast around its own axis, just a short 3 times as fast as the Earth rotates. Of Jupiter is considerably colder than the Earth. The reading comes from the cloud tops show that the temperature is about -101 degrees Fahrenheit. Jupiter is marked with great swirls of clouds and best-known feature is the Great Red Spot. The Great Red Spot is a large storm that measures about 24,860 miles across. It is large enough to store just shy of three planet Earths! Another important aspect of Jupiter is a large number of satellites, or moons. The current tally is 63

Saturn

Saturn is the second largest planet, located about 746 million miles away from our planet Earth. This is almost twice as far away as Jupiter is from Earth! In its orbit around the sun, Saturn range of 840 million miles to 938 million miles from the Sun. It takes Saturn nearly 30 Earth years to make it around the sun Like Jupiter, Saturn is spinning on its axis faster than the Earth. Saturn takes only 10.67 Earth hours to rotate once on its axis. Cloud top temperatures show a temperature of -274 degrees Fahrenheit. It’s twice as cold and record the temperature of the planet! The most prominent feature of Saturn’s rings thereof, which are mostly of ice and rock particles. Saturn’s ring system actually consists of many smaller circles instead of one large ring. The particles range in size from a couple of centimeters to kilometers in size. Saturn, like Jupiter, also has a large number of bodies, and this number now but the 60 moons.

Uranus

Uranus marks the place where we begin to discuss distances of billions of miles, not a million miles. Uranus is 1.6 billion miles from Earth, which is a little less than twice as far away as Saturn is from Earth. This figure alone can help us to begin again to take great extent our solar system. Uranus between 1.7 billion and 1.87 billion miles from the sun in its orbit. Uranus takes 84 Earth years to make one revolution around the sun in the average human life, Uranus will make just one way around the sun How long does one day on Uranus last? It takes Uranus over 17 hours to spin once on its axis. Temperatures on Uranus are even colder: -328 degrees Fahrenheit. Uranus boasts 27 known moons and faint ring system.

Neptune

acknowledged last planet in our solar system is Neptune. Neptune is closest to our Earth when it is 2.68 billion miles away. The closest distance of Neptune from the Sun is 2.77 billion miles and 2.87 billion miles away far from her. It is nearly 30 times as far from the sun as the planet Earth! Although it seems that time Uranus takes to revolve around the sun is very long, Neptune takes almost twice as long. It takes 165 Earth years for Neptune to make one trip around the Sun. A day on Neptune also takes 17 hours. Temperatures in the cloud tops are just a little bit colder than the temperature of Uranus: -346 degrees Fahrenheit. Neptune has 13 known moons and faint ring system. The most prominent feature of Neptune needs to be a beautiful blue color that methane clouds reflect back to the viewer. Neptune also possesses huge storm like Jupiter and is called the Great Dark Spot.

Conclusion

As you can see, the further we go out in our solar system, we can begin to see how expansive universe. Our solar system orbits just one star of the billion stars in the Milky Way, which is just one galaxy a billion other galaxies. Learning about the outer Solar System is just the beginning of many areas to discover about the universe.

Sun logo or just plainly “signal” is associated with many stereotypes that are usually the first things you hear about before learning astrology. Here are some of the popular ones.

Log? Sun Sign?

In Western astrology, the sun goes in and out of the 12 signs of the zodiac about once a month. If you do not know the Sun logo, or just on the edge and are not sure, do a quick search.

I do not mean guilty they are all described below.

Aries: stupid and impulsive

core

Fire sign Aries is adventurous and innovative. They are stereo, usually known for being naive, impulsive and aggressive.

The Real Story

Aries, the first sign of the zodiac wheel, is believed to be the youngest of the journey of the universe. They can be aggressive, outspoken, and sometimes very much. Unlike most markers, but they really do not have to second guess themselves- they often get things right. They are moving fast and always looking. Fresh and new views of the world remain attractive and competitive side but always growing. Wisdom, however, well, they will not be dogmatically recite what they have read the old dusty books- they learn more from the experience they gain in time.

Taurus: The Penny Pincher

core

Earth sign Taurus is solid and practical. They are stereo, usually known for being materialistic, stubborn, and too cautious.

The Real Story

Taurian Suns often get stuck with a fairly selfish role to be stingy with money. In truth, this sign is often a very complicated relationship with money / assets. They see that they have to play the game, as others do, to make a living, but this is not always fit career goals. They are often very creative and if they can learn to mix this with earning money, they will be happy and generous to people in need. Otherwise they will continue to have a strange love / hate relationship with it. In focusing so much on Taurus’ stubborn and materialistic ways people often forget to describe the good taste this symbol is for the finer things in life and powerful energy of

Gemini :. The Fickle Jack-of-ALL Business

core

Air sign Gemini is curious and responsive. They are stereo, usually knows to be variable, unstable, and have a poor memory.

The Real Story

Although many Gemini Suns are proud to be the “twin” this is not quite it. This variation is flexibility rather than a split personality. Gemini Suns can jump between extremes and stay healthy. They want to learn a little bit of everything to experience and communicate / connect with others.

restless energy of has them jumping from one to another, as well. As for their memory, this is common with table controlled by air, not necessarily just to have a Gemini Sun. There is no mistake, though Gemini Sun prefers to keep the light and if they do forget something else feel important, they were simply thinking of another Parliamentary this will reoccurring misunderstanding for Gemini Sun in personal relationships.

Cancer: The Home- Body

core

Water signs Cancer is the leading and caring. They are stereo, usually known to be anxious, moody, passive and aggressive.

The Real Story

Cancer Suns have had a real bad reputation. It seems like everyone has a comment of domestic and Moody their ways, but really, you’ve got to give cancer a little credit. This signal is the cardinal quality of the water element, because those leaders in all that involves the media, intuition and clairvoyance. Even if Cancer Sun is not psychic, they have a deep vibrational energy that is underlying and strong to those who can see a sixth sense. To explain their need for home- Cancer Sun is nostalgic and feel deep childhood- they know that these roots color pattern in the future, as well as the ability to let love in

Leo :. The dramatic Performer

core

Fire signs Leo is proud and dignified. They are stereo, usually known for gaudy-costume, attention-seeking, and leadership.

The Real Story

It is quite untrue to the Leo Sun isn ‘t a little showy, but there is more to them that meets the eye. Sure they boast and brag, but their confidence is contagious. Others feel important around them. Leo Sun believes the bravery and heroism. Their message is true and they commend others for their strength. SO positive they can be dramatic in the case for the rest of us, but they believe in what they preach and what they create

Virgo :. The Health Nut

core

Earth signs Virgo is hardworking and self-aware. They are stereo, usually known for his modesty, critical mind, planning and health conscious.

The Real Story

In modern Virgo Suns have worn these crude conceptions. They are now becoming known for its charm, independence and common sense. The health concerns, however, stem from sensitive gastrointestinal (this sign rules the intestines), which takes place mostly only 1 and 2 decal Virgos, (about from 22 to 23 August in September, 10-12.) This does not always mean that they are health nuts, but many decided to remove meat or dairy products from their diet in later life if it starts to become a problem

Libra :. Superficial

core

Air sign Libra is the balance they want to weigh things out and compare / contrast. They are stereo, usually known for their love of beauty, justice-seeking, and see just what is on the surface.

The Real Story

I’m Libran Suns to misunderstood. They are idealists * and to try to rid the world of filth they reach only the smoke and mirrors. Without Libras would be much less beauty in the world, justice and adventure of love and companionship were all but Carnal desires. I do not think it should be viewed as “superficial” but more subtle tenacity in bringing the beauty and harmony to the world through his own reflection as a gesture

Scorpio :. Possessive & Intense

core

Water signs Scorpio’s autopsy and reflective. They are stereo, usually known to be hypnotic, heavy and especially possessive.

The Real Story

Scorpio is very easy to take the signal out of crowd- they seem determined and ready to defend themselves. Neighbors this sign are Libra and Sagittarius- both considerably lighter than Scorpio.

* If you have Mercury in different signal than Scorpio, your mind will not keep brilliant dissection qualities this symbol has to offer and you will usually be much lighter in spirit.

Scorpio Suns seem synonymous with mystery and what is hidden. Previous experience has conditioned them to be untrustworthy. The possessiveness simply misunderstood. Scorpio does not want anyone they just want to have one’s loyalty

Sagittarius :. Overly Frank & Blindly Optimistic

core

Fire sign Sagittarius is philosophical and freedom-loving. They are stereo, usually known for being sarcastic, blunt and overly optimistic.

The Real Story

Sagittarius Suns are philosophers Zodiac. They could go for days on end meta physically open all the doors and possibilities. Sagittarius as a person’s confidence in the universe that is misunderstood largely. This optimism can get them in the strangest of circumstances and will probably make them many new friends. I would not say that they are completely blind to the negativity and cynicism- they are just indifferent to it

Capricorn :. The Old Goat

core

Earth sign Capricorn is ambitious and self-reliant. They are stereo, usually known for being set in their ways, slow-moving and cynical.

The Real Story

The Sun put the dead in winter, in Capricorn gets a reputation for being a bit boring. Capricorn Suns are focused on a career in this, all they from being very ambitious to crazed workaholic. People sometimes think that Capricorn did not listen to snatches it seems that this man is thinking of better times “good ol ‘days” and not open to new proposals. The truth of the matter is, Capricorn has fought for what they have earned, and feel that others should work as hard to earn what they get in life they have little trouble in seeing any short cuts to success just for this reason . All the earth signs, (Taurus, Virgo, Capricorn), potential geniuses with material and secular values, although anyone with a little ground in their charts are bound to misread the “materialism” or “boring”.

Aquarius: Very Impersonal

core

Air sign Aquarius is friendly and humanitarian. They are stereo, generally known to be a people watcher, eccentric, and personal cold.

The Real Story

It may sound a bit strange- when people think of Aquarius Sun they think of a man who is kind and generous. Aquarius generally well with large groups and shy away from one-on-one conversation. Personally Aquarius Sun can be described as cold and spiritually. Aquarius is perhaps the most misunderstood of all the signs. They observe people and learn the appearance of them so when they get up close and personal, spiritual theories intercept their emotional reactions. So, yes, everyone will quirky Aquarius friend but they must remember that they are not so easy to achieve

Pisces :. Easy to confuse and Spacey

core

Water signs Pisces is imaginative and sympathetic. They are stereo, usually known for being impressionable, Spacey, and easily damaged.

The Real Story

As the last sign of the zodiac cycle, Pisces is usually considered to be the wisest, but many think it to be a little air-headed. They often have specific ideas and escape the “real” world to retreat to day-dream world. They are easily forgive and this is considered weakness- it is regarded as naivety place of compassion. Why Pisces get such a bad reputation? Because most feel they do not need to explain themselves- they are what they are, it is what it is, and this, too, shall pass.

The Long Count calendar of the ancient Mayans ends on the winter solstice of 2012. Many scientists and astronomers have been looking at the Mayan astronomy for many years now and are considering if the end of the world as we know it is at hand.

The Long Count calendar began mapping the sky on the day that this current age of the earth began 5100 years ago. All the scientific evidence points to the Mayan prediction astronomy to be exact.

There is a huge importance in 2012 in the lunar-solar records, cosmic events and ancient knowledge all point to the galactic alignment of the end of 2012. The Mayan astronomy predicts exactly this galactic alignment. All of the up to date astronomical software shows the Galactic alignment is set to happen on December 21, 2012.

center of our galaxy, the Milky Way, will coordinate with the ellipses of our solar system in conjunction with the eclipse and very irregular planetary travel. The last time that this planetary alignment was the 26,000 years.

Even before any modern technology advances in astronomy, it was known that there were other planets in our solar system. As evidence comes from ancient records. In 2008, the impression of the planet was behind Pluto, and is believed to be 10 planets in our solar system. How close it will come to earth in 2012 is not yet known, but ancient Mayans knew it was there and expect back in the year 2012.

When man first landed on the moon, a large number of people were still skeptic about the validity and reliability of relevant human feat. In fact, the then Russia, rumors were spread that the footage shown on the “giant leap for mankind” Neil Armstrong was just a Hollywood-made video made to show that the United States is ahead in the race for the last frontier – space. But achievement turned to be true and real, and space expeditions remain. Fascination human space has been since time did not mention. In fact, if you ask children what they want they want to be when they grow up, three of their list would have to be an astronaut. But before you can be one, lay down that telescope and let us go a few important facts about astronomy.

The word “astronomy” was coined by a combination of two Greek words, Astron which means star and Nomos who represents the law. There are two types of astronomy, observational – relating to monitoring, purchase information, evaluation of this data and generate a hypothesis based on the standard laws of physics. Another type of theoretical astronomy respect more on the production and development of analyzes types of computer Inputting basic laws of physics to manipulate and briefly explain how celestial bodies move. Because of these two astronomy classes, facts about the heavens above were formulated and grace. Take this example.

• It takes 8 minutes before the sun reaches the earth. The sun can also cause a changing world weather and the size of marine currents.

• The sun, though massive in area, is just an average size star.

• What about this important fact to know about astronomy, lightning is more than twice balloons than the sun.

• Some Important Facts to know about astronomy, especially the moon – each year, the moon moves away from Earth about 3 centimeters.

• The moon is the only other moving body in the universe that has placed his foot on.

• As far as navigation and guidance, and astronomy is concerned, the North Star, which is also known as Polaris, is the only star that does not move every night, and it is one reason why it is an invaluable tool in nautical moved.

• Venus, in contrast to other planets, is the only one that’s in reverse, from east to west.

• planet Neptune has not completed orbit around the sun since the discovery 150 years ago.

These are some important facts to know about astronomy and there is much more to discover since space is so vast.
