Jupiter
astronomerGalileo Galilei
Galileo Galilei was an Italian astronomer and physicist who pioneered telescopic astronomy, discovering the four largest moons of Jupiter.
historical discoveryThe Galilean Moons of Jupiter
In January 1610 Galileo saw four points of light beside Jupiter that changed position night after night — moons orbiting another world.
surface featureUruk Sulcus
A swath of the bright, grooved terrain that covers much of Ganymede — younger ice, tectonically resurfaced into parallel ridges and troughs.
moonCallisto
Callisto is the outermost of the four Galilean moons of Jupiter and is heavily cratered.
moonEuropa
Europa is one of the four Galilean moons of Jupiter, covered by a shell of water ice.
