Interesting Facts About Astronomy

Astronomy is an interesting science to many people because it is filled with many astronomy fun facts. Everything from the size and temperature of our own star, the Sun, to the make-up of distant planets has been established. All of this information can be retold to entertain and enlighten people.

The Sun is a great source of astronomy fun facts. Our own star, which supplies us with all our heat and light is between 91 and 94.5 million miles from Earth. It’s not that nobody has measured the exact distance. It’s because the Earth revolves around the Sun in an elliptical, uneven, orbit, so the distance varies depending on where the Earth is situated in that orbit.

The Sun is only of average size for a star, yet it’s size is another terrific source of astronomy fun facts. As average as it is, it accounts for about 98% of all the matter in our solar system. Even with the huge planet of Jupiter on our side, we’re still a tiny 2% of non Sun stuff.

It would take the diameter of about 100 Earths to stretch across this average Sun. The solar winds produced by the Sun extends to about 50 times the distance from the Earth to the Sun. Or put another way, those solar winds go out about 50 AU’s, with an AU being the distance from the Sun to the Earth. That’s quite fantastic, isn’t it?.

How about astronomy fun facts that don’t have much to do with the Sun? How about the Moon? It’s the only non-Earth object upon which man has walked so far. And one man actually travelled to the Moon but never left it. Dr. Eugene Shoemaker loved the Moon but was rejected as an astronaut. After his death he was cremated and his ashes were scattered over the moon by the Lunar Prospector spacecraft in 1999.

There are many more astronomy fun facts about the Moon. It’s the site of what may become the oldest footprint known to man. Neil Armstrong’s giant leap for mankind left a print in the Moon dust that will likely still be there in 10 million years time.

Many people, in fact about 13% of those polled in 1988, still believed the Moon to be made of cheese. And finally the suits worn by the Moon-walking astronauts weighed 180 pounds on Earth but only 30 pounds on the Moon, because of the reduced gravity on the Moon. Talk about an instant diet, eh?

Astronomy fun facts aren’t limited to our close astronomical neighbours. Looking at stars is like looking into the past. Some of the stars we see today in the night sky are so far away that their light takes a million years to get to us. Some of the stars you see may really be images of stars a million years old that aren’t even there any more. There are over 1 x 10 ^22 stars in the universe. That’s a 1 followed by 22 zeros. The number is really quite staggering.

There are millions of astronomy fun facts and we could go on about them forever. But unfortunately, this article can not. So, please, walk out there and learn more about astronomy for yourself.

Astronomy For Beginners

Although astronomy is the oldest science, it is still at the forefront of not only scientific thought, but also that of the public at large. Who hasn’t gazed up at the stars while walking home late at night and wondered about something larger? Having said that though, the ancient people of definitely the northern hemisphere, but probably both hemispheres, knew the movements of the stars and planets better than the majority of us do today.

They understood even then, thousands of years ago, that the majority of stars appear to rise in the Eastern skies at night and travel on circular paths. They also noticed that some ’stars’ were ‘wanderers’ (we call them planets) and that sometimes they went ‘against the flow’.

They also named groups of stars that we now call constellations or even galaxies and knew that those visible in the winter were different from those visible in the summer.and that others were visible all year round. The average common man of 5,000 – 10,000 years ago almost certainly knew more about the movement of the celestial bodies than the average common man of today does. (I mean men and women here, of course).

They learned how to calculate or at least locate the extremities of the sunrise and went to extraordinary lengths to mark those positions with huge stone structures, such as Stonehenge in the United Kingdom, probably to facilitate the location of certain positions of the sun or other planets or stars, which may have been important to their religious beliefs or crop cycles.

In 1609, Galileo invented the first artificial device for studying the stars and planets. It was the first astronomical telescope and through it he was able to observe objects millions of miles away that no person had ever seen before. Because of the deductions he drew from his observations, he clashed with the Roman Catholic Church and was often in serious danger for his life, so radical were his discoveries.

But humankind was not to be put off, and since then we have gone on to build ever bigger and ever better astronomical telescopes with which we can even detect radio waves, microwaves, X-rays, infrared waves and gamma waves from outer space. Forty years ago, we even travelled to our Moon. and we have sent probes to eight of the nine planets in our Solar System, as well as to quite a few comets and asteroids.

Where will we go next? That decision was always up to the government of the USA and the old USSR, but now there are other contestants in the field. What will China or India want to explore with their possibly slightly different outlook on life? Or will it be only a question of financial benefit?

The world may be in a state of flux and power may be shifting from its traditional seats, but it has not diminished interest in questions that scientists think can only be answered in space. These are exciting times in the science of astronomy, but then man has always found astronomy exciting.

Astronomy – Important Dates Before Christ

There is no uncertainty that astronomy is the oldest science and there is also no hesitation that astronomy was being studied by everyone, not only the wise men, thousands and thousands of years ago.

We do not know precisely why they did it, but we can surmise that early man noticed a correlation between the weather and the stars, which were themselves not fully understood, of course.

Early man, probably even as far back as Neanderthal man, noticed the relationship between the weather and herd movements and crop growth, or at least fruit and nuts on local trees, if they did not have planted crops.

This means that people could see a connection between the stars and food availability. This relationship was probably ritualized into some sort of religion like early Wicca. Therefore, the stars became a very important part of the lives of every single person and it is likely that astrology and astronomy were widely intermixed by the average person.

However, there were also people who did not only use the stars as some enormous celestial clock and who tried to make sense of the whole shebang. I am going to narrate below, eight of the most significant dates or years in the history of astronomy before Christ walked on the Earth. Never forget that they had nothing but an abacus to do there calculations and no telescopes, which came about two thousand years later.

585 BC: Thales of Miletus (c. 625- c. 547), a Greek, predicted a solar eclipse in Asia Minor purely on the basis of his observations and calculations. It was not a lucky guess!

c. 400 BC: the astronomer Oenopedes (5th. century). also a Greek, announces that the Earth is tilted on its axis with respect to the Sun.

352 BC: the Chinese report what they called a ‘guest star’, a supernova, which was the earliest reported sighting.

340 BC: The astronomer, Kidinnu (b. Babylon c. 379 BC) discovers the precession of the Equinoxes, ie the apparent change in the position of the stars caused by the Earth’s wobbling on its axis.

c. 300 BC: a ‘committee’ of Chinese astronomers compile star maps of the visible universe.

c. 240 BC: Chinese astronomers observe and make notes about Halley’s Comet. Also Eratosthenes of Cyrene (c. 276 – c.194 BC), a Greek, correctly calculate the Earth’s dimensions.

165 BC: Chinese astronomers notice sunspots for the first time.

c. 130 BC: the astronomer Hipparchus of Nicea (b. 147 BC), a Greek, correctly calculates the distance to the Earth’s Moon and also rediscovers the precession of the Equinoxes.

You will see from the dates above that obviously not everyone let nature and the stars govern their lives, as the common farmer or hunter did. Some men actually took pen to paper, but before pen and paper even existed, and tried to work out ‘why these manifestations occurred?’.

These individuals must have been extraordinary men to have worked these measurements out by calculation, observation by the naked eye and rationalization alone.
