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 interested in astronomy because he wanted to understand the nature of the universe and the movements of celestial bodies. He also developed a passion for observing the night sky and making new discoveries that challenged existing beliefs about the cosmos.
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.
What. Contribution did galileo make to astronomy
Yes he's known as the father of modern astronomy he found out that the earth was round
Astonomy is fundamental to our understanding of the universe in which we live, and intelligent people generally desire such understanding.
galileo galilei was interested in astronomy because he saw lamps swinging at church.
He discovered that the earth orbits around the sun.
Modern astronomy.
From 1609 till his death.
Galileo Galilei studied physics, astronomy, mathematics, and the scientific method. He is best known for his work in the field of astronomy, where he made significant contributions to the understanding of the motion of celestial bodies and the structure of the universe.
Galileo !
He discovered the four moons of Jupiter.
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.
