What did Galileo see when he observed Jupiter through his telescope? His discoveries undermined traditional ideas about a perfect and unchanging cosmos with the Earth at its centre. The planet was surrounded by four "stars" in the sky. He also discovered 4 of Jupiter's moons. Answer (1 of 2): Galileo would have seen cloud cover (as we do today), but did notice the phase changes as he studied the orbit over the 7+ months Venusian year duration: (light side / dark side) of sunlight on the globe (as described by Jeffrey Blanchard's good answer). Until then, it had only been seen with the naked eye. An icon used to represent a menu that can be toggled by interacting with this icon. What is Galileo telescope?
