Galileo Galilei was an Italian astronomer, physicist, and mathematician who played a major role in the Scientific Revolution. Using an improved telescope, he made groundbreaking observations: the moons of Jupiter, the phases of Venus, sunspots, and the rough surface of the Moon. These observations supported the Copernican model that the Earth orbits the Sun, not the other way around. His book Dialogue Concerning the Two Chief World Systems (1632) argued for the heliocentric model, leading to his trial by the Roman Inquisition. He was found "vehemently suspect of heresy" and spent the rest of his life under house arrest. Despite this, his work laid the foundation for modern physics and astronomy. He is often called the "Father of Modern Science."
