Jupiter's moons, as see from Earth, are close to Jupiter, which is now (Feb 2015) very bright and high in the sky in the northern hemisphere from about 21.00 to 03.00.
The moons Io, Europa, Ganymede and Callisto can be seen clearly with a 3" refractor and a magnification of about 40, but they can just about be detected, not very clearly, with 10x50 binoculars.
The four largest moons of Jupiter discovered by Galileo are Io, Europa, Ganymede, and Callisto.
Galileo Galilei named Jupiter's four biggest moons after figures from Greek mythology: Io, Europa, Ganymede, and Callisto. He discovered these moons in 1610 using a telescope.
Jupiter's moons were discovered in 1610 do not think I am lying because galileo is my great grand father.
He could only make out four of Jupiters' largest moons.
Jupiter's largest four moons, called the Galilean satellites because Galileo was the first person to see them, are Europa, Io, Callisto and Ganymede.
Galileo used his telescope to look into space where he noticed that Nicalous Copernicus was correct in saying that the Earth revolves around the sun. Which Galileo was arrested for believing.
It was sent into Jupiters atmosphere due to the possibility of an ocean beneath the icy crust of jupiters moon europa. Galileo could potentially be carrying bacteria that could be harmful to europa, so was destroyed to protect it.
jupiters ice moon is Io
we can't use jupiters moons for anything because fistly we can not get out that far to reach Jupiters moon and if we could it would take thousands of years and Jupiters Moons would be to big to do anything with anyway. so the answer to What could Jupiter's moons be used for? is....Nothing.
it's moons
