He was an Italian astronomer, physicist, mathematician and philosopher whose contributions had a significant role in the world's scientific revolution.
Galileo was a well-known, well-respected scientist for many reasons. Galileo started seriously compiling evidence in
favor of the heliocentric system in 1609, when he built his first telescope. While many works claim that Galileo
invented the telescope, he did not. He heard about a device that was designed for the military by Hans Lippershey. It
was essentially a “tube” with two lenses, and it magnified distant objects. From the description he heard, he was
able to determine how this invention worked and quickly built one for himself.
He was able to show that the planets do not shine on their own. He demonstrated that the planets appear as lights
in the night sky simply because they reflect the light of the sun. In addition, he showed that the light coming from Venus went through phases, just like the Moon.
