Galileo attended medical school in Padua, but questions about physical phenomena captured his curiosity and through his investigations, he discovered a number of underlying laws of physics governing motion and dynamics that remain at the foundation of modern science. He turned his attention to astronomy in the early 1600s, and with his telescope discovered craters on the moon, sunspots and four moons of Jupiter. His observations of the phases of Venus demonstrated the accuracy of the Copernican model of the solar system. He published a comparison of the Copernican and Ptolemaic systems, which included the disparagement of an argument for the Ptolemaic system favored by the Pope. This caused trouble with the Catholic hierarchy, and Galileo was placed on house arrest and forced to publicly renounce his Copernican theory.
