[[Galileo Galilei]] studied Jupiter extensively  and in the process discovered its four largest moons--[[Io]], [[Europa]], [[Ganymede]], and [[Callisto]], also known as the [[Galilean moons]]. Many other astronomers studied Jupiter from Earth-bound telescopes for hundreds of years. In the process they discovered twelve of Jupiter's moons and the Great Red Spot, but did not discover Jupiter's ring system.

Seven spacecraft, all from the [[United States]], have visited Jupiter thus far. First to do so was [[Pioneer 10]] (December 3, 1973), which suffered tremendously from the radiation belt but still provided the evidence for Jupiter's [[magnetosphere]]. [[Pioneer 11]] was next (December, 1974) and took far better images of Jupiter and its Great Red Spot.
