Jupiter Galilean System

Jupiter's Galilean System 1

One of the most significant discoveries of Galileo Galilei was the existence of the system of moons orbiting the planet Jupiter.  He made this discovery through a telescope he fabricated in his own workshop.  He first observed the system on January 7, 1610.  It is a tribute to his keen sense of observation that he deduced the true nature of the system.  By careful observation he determined the "stars" that were moving in such a strange manner were indeed not stars at all but were small celestial bodies moving around the planet Jupiter.  His discovery supported the Copernican theory of a Sun centered "universe".  His controversial discovery and his support of Copernicus's views led to his imprisonment by the "Inquisition".
