Galileo Galilei

Bio
Galileo Galilei was born in Italy in 1564. At the time, Italy was a church country and was religious, which means that they believed that everything orbited the earth. Then, in 1610, he made a grand discovery, with a telescope. He discovered that the moon was not smooth. In the past, Italian people thought that the moon's surface was smooth. But he discovered that it wasn't. And they also thought the same about the sun, but he discovered that there were sunspots on the sun. Then, he discovered 4 moons orbiting Jupiter. Which means that not everything orbits the earth. He got into trouble with the Church when he explained it to them though. Instead of believing him, they were mad, and did not believe him. He was under house arrest. In that, he published books, but that also got him in trouble too. And then he died in 1642. He is now known as one of the founding fathers of modern science.

What he is famous for
Galileo was famous for finding out that not everything orbits the earth. While Nicolaus Copernicus had the same theory too, but Nicolaus thought that the sun was the center of the universe, but really, the sun isn't.
