Galileo Galilei was a genius of many talents who lived from 1564 to 1643. His discoveries not only revolutionized astronomy, but also made advances in the sciences, mathematics,music and art. Although Galileo was a religious man, he often challenged the ideas of the Church with his theories and with his beliefs in the Copernican system. Galileo sought truth, which he believed was all around us.
Galileo is most famous for his use of the telescope as an astronomical instrument. His telescope allowed him to see the moon, sunspots, phases of Venus, and the moons of Jupiter. He demonstrated that the Copernican system was correct; the Earth and other planets revolved around the Sun.
