Explanation:

Galileo was Italian astronomer and physicist. He went to University of Pisa to study medicine but due to his interests he left medicine and became a professor of mathematics.

In 609, he built a telescope and became the first person who looked at the moon through a telescope. He also used the newly discovered telescope to discover four moons of Jupiter, study the sunspots on the sun, observe the phase of Venus and study Saturn.
