He literally put his life on the line advocating that the church (which believed that the earth was at the center of the universe and that the sun revolved around it because of their interpretation of The Bible) look to science first when trying to solve problems in nature.
The church tried him, threatened him with torture and execution, and eventually he recanted so as not to be tortured to death.
People in the same era were simply burned to death for lesser heresies, Galileo was a bishop in the church and a friend of the pope, so he got away with a lot more. I think of him as the Lenny Bruce of science. Just like LB is a big part of the reason why people like george carlin don't get arrested for their comedy, Galileo is a big reason why people don't (anymore) get arrested for teachings evolutionary Biology and other subjects.
Galileo was the first scientist to actually use the scientific method; Problem, hypothesis, experiment, observations, data, and then conclusion and discussion. Before that point scientists did not formally use this, you could say he invented the way we do science at its most fundimental level.

Some of Galileo's most significant work was in the field of kinematics, identifying that the total ...by him (or to be written by him) were forbidden, though this latter part was not enforced. ... Galileo Galilei - major areas of study ...
Urania - Goddess of Space, Astronomy, and Astrology.
I believe that at the time of Galileo and other pioneers in astronomy there was no formal astronomy study; he (and others) must have learned most of what they knew by themselves.
