Europa is one of Jupiters moons. Jupiter has many moons, but Europa is one of the four large moons that was discovered in 1610 by Galileo Galilei (and possibly independently by Simon Marius around the same time).
Europa has ice on it and it is hypothesized that there is an ocean of water below the ice.Some have suggested that there is life on Europa. The Europa Jupiter System Mission (EJSM) has been proposed to investigate this and other aspects in a 2020 launch.
