aug 7, 1550 - Galileo and Astronomy

Description:

"Using his telescope, Galileo was able to make all sorts of new discoveries. He found out that the Moon was not really smooth, but covered with craters. He also thought that the moon didn't make its own light, but reflected light from the sun. Other discoveries included the moons of Jupiter, the phases of Venus, and sunspots. After recording and studying his observations of the planets and the moon with his telescope, Galileo believed that Copernicus' theory of the planets, including the Earth, rotating the Sun was correct." (Ducksters).
