Galileo's observations of the night sky in the early 1600s confirmed a new model of the universe, in which the Earth orbited the sun—and not the other way around, as his contemporaries believed.

Galileo'''s observations are the foundation of our basic understanding of the universe the sun, encircled by orbiting planets, is at the center, and not the Earth.

Galileo was tried, threatened with torture, and forced to recant his perfectly correct position about the solar system being centered around the sun, instead of around the earth.
