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.

Astronomers have realized that all the time they spend in the organization and set up their telescopes and other devices can be saved with the help of the observatory funds. Without Observatory, astronomers have to spend most of their time in planning instruments and materials involved in taking photographs. There are two reasons for this. First of all such equipment is highly technical and sensitive use. With more technology they are difficult to use. The larger the telescope, the harder it is to manage settings. Second, the constantly changing trends of weather makes it harder. When the devices are ready, go to the weather changes and all efforts futile. Ignore modern technology is almost impossible in every single field. All work and set a modern piece of technology to survive in modern society and compete. Observatory of funds makes it easy for astronomers to manage and organize their documents. These funds take sixty percent less time in the organization and it is more likely that the results would be best. The team would not need to carry their equipment and put it all back when they need to use it. For private equity, there are two options. First one is the home of the dome and the second is pre dome type dome. Both are available in certain information that matches demand astronomers.

observatories for sale have different types of material used today. Some parts of the capital are made from high quality fiberglass but some things are constructed with high density HDPE / polyethylene. The fiber glass used is absolutely free from any form corrosion and polythene is strong, weather resistant and durable. Both of these materials are selected for their qualities which makes them perfect for outdoor structures. Such Observatory for sale can be organized anywhere. A pre dome type can be located on any normally ground or field. The Dome can be installed at the base of wood or gravel. A rotating dome depends on good and solid foundation, and the foundation must be strong and tight. Basis dome is expensive part of the whole process.

Automatic Observatory would work and turn without the help of human hands. Bulge can also be automated so that the shutter will open or close in accordance with the use of the telescope and also to protect delicate parts in strong or worse weather condition. The Dome has to unplanned with electric rotating system. Nowadays DDW or digital dome work is very common in observatories. Mostly it is not necessary to add electrical equipment in the original construction of the dome. Customers would want to buy a physical operational Observatories first and then they would gradually replace auto and motor systems.

After the sale of these Observatory domes, it is mostly one-year warranty on them. Dome observed and checked right buyer, even though they offer a guarantee. You can also make changes or repairs but can not give them back and get all the costs back. So careful analysis important buying dome. Also, the buyer must ensure that he has a good base and place the dome. It will be located in the best place for great results and appropriate services. An observatory dome has had great importance in the eyes of astronomers. All their work is now as simple as it could be with the help of the observatory dome.

To understand the moon phases you should first monitor changes in the sizes of the moon and when it seems so. Figure moon formed in the reflection of sunlight from the sun shining on the earth’s surface. The moon phases are a great part of the study based on a series of movement is what makes the moon unique in the universe. In fact, in ancient days, it was the moon that plays the role of the time reference and predict the best fishing times. Because the moon and its benefits, people noticed changes in the picture of the moon, studied and completed many things.

One of the conclusions that they found out the moon phases are constantly spinning. They go round and round without ending and each cycle is similar to the previous cycle. There were no equipment or technical devices to remind them of the time, the prehistoric inhabitants had only the moon to be their guide in life, as well as strong sun phase of the moon indicates the time or month of the year, but it was not indicated exactly in the form of month as how we’re represents a regular month. But of course, use the moon was a difference from one culture to another, one religion to another.

Although the moon appears to be changing, according to moon phases, it is literally changing. It was the amount of light it reflects is constantly changing. The moon is always the same and the light does not affect the shape of the moon in any way. In fact, it has no power light and it gets light from the sun Most people are unaware that they thought that it is capable of glowing and beautiful bright. As a matter of fact, the moon is a mysterious yet very fascinating thing.

Careers in astronomy

Students who are willing to take up jobs in astronomy will be ready to work hard around the clock. This field requires single-minded concentration and great patience to monitor minute changes taking place in the space and the behavior of different planets and the stars. It is a very demanding field of work that requires a lot of knowledge in mathematics and physics.

Where to work?

National Aeronautics and Space Administration is considered to be a dream job of astronomers where they can use their skills and knowledge in vivid research and experiments. NASA is playing a key role in taking up more and more space missions to explore outer space. Such projects are usually taken up in large groups. These teams are made up of skilled astronomers from all over the world who work in unison to find out deep secrets of nature and origin of the life.

high-end facilities and networks provided by the government to make it possible to make high quality astronomy work at colleges and universities also. Astronomers do not only work on a space mission, but there are also varied. If you are interested in engineering work, you can work on designing complex devices used in different projects space. These equipments require high precision and accuracy.

BA and Master’s degree in astronomy

Students who opt for BA and MA degree in astronomy have limited career opportunities in this field rather than those holding doctorate. These people can act as data analysts NASA research groups. That work will be very interesting, but they will not be having the option to choose their own projects to work on.

Other interesting jobs for graduates and post-graduate students of astronomy in the planetarium as teachers. Spectrum work does not end here only. A curious mind to find diverse ways of survival and so is the case with graduates astronomy too. By choosing Astronomy functions can teach physics and higher mathematics in secondary schools and universities. What can be more interesting than teaching the subject of your interest to other avid students as you are?
