Detailed explanation-1: -By Jan. 15, Galileo correctly concluded that they were not stars at all but moons orbiting around Jupiter, providing strong evidence for the Copernican theory that most celestial objects did not revolve around the Earth.
Detailed explanation-2: -Galileo Galilei (1564-1642) was part of a small group of astronomers who turned telescopes towards the heavens. After hearing about the “Danish perspective glass” in 1609, Galileo constructed his own telescope.
Detailed explanation-3: -In January 1610 he discovered four moons revolving around Jupiter. He also found that the telescope showed many more stars than are visible with the naked eye. These discoveries were earthshaking, and Galileo quickly produced a little book, Sidereus Nuncius (The Sidereal Messenger), in which he described them.
Detailed explanation-4: -An excerpt from Galileo’s Sidereus Nuncius, showing the “Medicean stars.” On January 7, 1610 Galileo Galilei pointed a small twenty-power telescope at Jupiter. What he observed changed the way we understood the universe. Galileo noticed what appeared to be three small stars near Jupiter.
