Before Galileo observed that Jupiter had moons of its own, the prevailing theory in astronomy was that everything in the universe revolved around the Earth, a philosophy known as geocentrism.
In 1610, Galileo trained his newly-invented telescope upon Jupiter, and observed what he at first called 'fixed stars' orbiting around it. This direct evidence that not everything revolved around us after all was the first large crack in the geocentric theory, and major evidence of Copernicus's competing theory of heliocentrism: that planets and their moons revolve around the sun instead.
