He discovered that the earth was round not flat.
He discovered it on the moon.
that the moon was not flat, it was a sphere.
Galileo made his first telescope in 1609, modeled after telescopes produced in other parts of Europe that could magnify objects three times. He created a telescope later that same year that could magnify objects twenty times. With this telescope, he was able to look at the moon,
Many of the larger craters on the moon can be seen from earth without a telescope, so nobody discovered craters on the moon with a telescope.
Galileo used his telescope to look into space where he noticed that Nicalous Copernicus was correct in saying that the Earth revolves around the sun. Which Galileo was arrested for believing.
In astronomy, he used a telescope.
He discovered it on the moon.

Galileo saw in his telescope when it was 1995
Galileo did not discover Saturn. Saturn was known to people who lived thousands of years before Galileo. Galileo was the first person to see Saturn through a telescope, and the first to observe its rings. He made many of his observations from Venice.
The telescope, invented by Galileo in the early 1600's, allowed us to see objects better that were far away. Galileo is credited with using his first telescope to discover Jupiter's moons, Saturn's rings, and the craters and other features of our moon.
