Europa

Europa AR

The giant planet Jupiter has at least 50 moons, including ice-covered Europa. Surveys of Europa by unmanned spacecraft--which also sent back the images seen here--indicate that there may be a deep saltwater ocean beneath the ice. On Earth, life exists wherever there is water. Is the same true on this distant moon?
