Europa is one of Jupiter's four Galilean Moons. It is thought that there may be simple life, such as bacteria, on or under it's icy surface, and this was one of the contributing factors in NASA's decision to crash the Galileo Probe into Jupiter, out of fear that bacteria could contaminate the potential oceans of Europa.
