    Galileo was a strong believer in the heliocentric theory (copernicanism). Galileo wanted to build on Copernicus' idea of the heliocentric universe so he built a larger scale of a childrens toy called a telescope. Galileo made many discovery's using his telescope including Jupiter's moons, and studying the phases of planet Venus. After he convinced him self that Copernicus' theory was correct, the catholic church made him withdraw his support to this theory.
