Hello! My name is Galileo Galilei (gal-uh-LAY-oh gal-uh-LAY-ee). I was born in 1564 in Pisa, Italy. I was one of the first astronomers, people who study the night sky. I built my own telescopes. When I looked at Jupiter through one of my telescopes, I saw four small moons going around the giant planet. So I was the first person ever to see moons around a planet other than Earth! Can you imagine what I saw?
Let me show you what astronomy was like in my life. Click Next to be transported back in time, to the days of “Old Time Astronomy.”
