Detailed explanation-1: -He subsequently demonstrated the telescope in Venice. His demonstration of the telescope earned him a lifetime lectureship. After his initial success, Galileo focused on refining the instrument. The initial telescope he created (and the Dutch ones it was based on) magnified objects three diameters.
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. He subsequently demonstrated the telescope in Venice.
Detailed explanation-3: -When Galileo pointed his telescope at Jupiter, the largest planet in our solar system, he made a startling discovery. The planet had four “stars” surrounding it. Within days, Galileo figured out that these “stars” were actually moons in orbit of Jupiter.
Detailed explanation-4: -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.
