Astronomy Facts

There are many different astronomy facts. First, astronomy is from the Greek for law of the stars. Second, as proven in the seventeenth century, the solar system is heliocentric, not geocentric. Third, astronomy is a very active field of physics because over ninety percent of the universe has not been examined or understood, due to limited technology, but not for lack of trying. With more research and more advances in technology, the field will grow. There have been many great astronomers over the history of the world, but Galileo is widely recognized as the greatest, since he is the one who literally changed the way scientists and everybody else viewed the world—he was the one who proved a heliocentric solar system. Other great astronomers included Tycho Brahe, who helped nudge the world toward a heliocentric view. Tycho Brahe was a very interesting character, who kept a dwarf named Jepp, and also a tamed elk that tragically died when he consumed too much beer and fell down the stairs.

If you are interested in learning more astronomy factoids, you can do so easily. The Internet actually has a huge number of great resources, including NASA very own webpage, and online journals and magazines dedicated to the study of the Universe. All branches of science always have new discoveries to make, but even though modern astronomy is four centuries old, it is still very much in the beginning stages of understanding and there is still a lot of work to be done.

Radio Telescopes
Radio telescopes are located far from busy locations in an attempt to avoid interference. They look similar to satellites, using the same “dish” technology.

Optical Telescopes
Optical telescopes are made by many different companies, but there are only three types of optical telescopes; refracting, reflecting, or combined-mirror system telescopes.
