Galileo was the first astronomer to build and use a telescope to observe the night sky. He made many important discoveries using his telescope, such as the moons of Jupiter, the phases of Venus, and the mountains and craters on the moon. While Copernicus proposed the heliocentric model of the solar system and Tycho Brahe made many observational measurements, Galileo's use of the telescope revolutionized astronomy and our understanding of the cosmos.
