Astronomy is one of the oldest sciences. It was started when the first thinking being looked up into the night sky, and wondered what it was. Many humans thousands of years into the B. C. era tried to give theories about what it was, like the belief in astrology (The belief that your fate is controlled by the stars and constellation). Other people built things to examine the universe with, such as Stonehenge, a structure made of rocks built in modern day England around 1848 B.C., used to examine the sun throughout the solstices. Even the heliocentric theory (that the Earth and other planets revolve around the sun), which most people think Christopher Colombus first thought of, was most fully developed by Aristarchus sometime near 300 B.C. Many things about the galaxy, however, still remain a mystery.
So you're wondering what the dictionary definition of "Astronomy" is? Let's see:
Astronomy The scientific study of the universe beyond Earth.
In particular, the observation of the positions, motions, and evolution of
celestial bodies and phenomenons. Astronomy should not be confused with
ASTROLOGY, a pseudoscience not supported
by any creditable evidence.
