∙ 14y agoGalileo Galilei discovered the four largest moons of Jupiter (there are more than four). They're still referred to as the "Galilean moons" to distinguish them from the other smaller moons of Jupiter and they can be easily seen in even a fairly modest telescope.

∙ 10y agoIt was Galileo in the early 1600s who first used a telescope to study the night-sky scientifically and he discovered the four big 'Galilean' moons of Jupiter. They can be seen through a small telescope like a 2" refractor with a magnification of 40-50.

∙ 15y agoI don't know who invented the first telescope, but I do know that Galileo Galilei discovered the 4 moons. That's why they're called te Galileian Moons (I hope that's how you spell it).
