Galileo discovered the four largest moons of Jupiter and that Venus showed phases like those of the moon.
With his telescope,Galileo discovered that the planet Saturn had a ring around it.He also spotted Jupiter's 4 largest moons,even though there is more than 4 moons that Jupiter has.

Galileo did not invent the telescope. The Italian physicist and mathematician improved on an existing spyglass design to create a more powerful one: a refracting telescope that he then used to study the night sky.
Galileo experimented with gravity. Newton merely explained how it works, and showed that if his formula is correct, then that explains why the planets move the way they actually do. He may never have needed to experiment.
Galileo was the first to use the telescope for astronomical observation. Galileo based his telescopes on ones he saw Dutch sailers on trading ships using. So you have to go back to the Netherlands to find earlier telescope makers/users. It is likely the Dutch may have adapted the idea from someone else before them.

Galileo was probably the first to study Jupiter in detail, with his telescope.
