Europa's frozen surfaceDespite Stephen Hawking's recent warning about the dangers of making contact with advanced alien life, NASA is moving forward with plans to seek life on planets and moons -- in particular, Europa, Jupiter's sixth moon. Europa is covered with ice, and astronomers now think that a sea of water, and possibly living organisms, lies under the ice layers.
This enhanced color photo of Europa was taken by NASA's Galileo spacecraft. This image provides a good view of Europa's surface.
