Well, he invented the telescope, and that's pretty huge. And he used it, too, to discover the craters and mountains of the moon, the 4 largest moons of Jupiter, and the rings of Saturn. And he did it all way back in 1610.
Galileo's main branch of science was astronomy, where he made groundbreaking contributions to the understanding of the solar system by observing the moons of Jupiter and the phases of Venus. He also contributed to the fields of physics and mechanics with his work on motion and gravity.
