Galileo Accomplishments

Whenever history is reviewed on Astronomy, great Scientists such as Nicholas Copernicus and Galileo Galilei must be mentioned for their great contribution in the world of Astronomy. Comparing Copernicus with Galileo, we see that Copernicus made great discoveries which Galileo would later use in making his scientific discoveries and proofs. Copernicus is regarded to as the father of Astronomy because of his great contribution towards making the universe understandable to many people. This essay focuses on major accomplishments of Nicholas Copernicus and how Galilei Galileo used them later to become successful scientist explorer.
Copernicus was a Renaissance astronomer and Mathematician who discovered that the sun was the center of the universe. He differed with the then common belief that it was the earth that was the center of the universe and that the sun and other bodies revolved around it. Little is said about Copernicus' view on multiple galaxies and the solar systems which are part of the universe. This is because he had no concept at all because the solar system and galaxies were small to be seen from the earth's surface using naked eyes (Armitage, 1951). This idea ruffled many scientists who could not agree with Copernicus and so at some point, his
