Ice Rafts on Europa

Europa_ice_rafts-galileo-1710x1320

This image is a close-up of the surface of Jupiter's moon Europa taken by the Galileo mission. The ice has been broken apart and "rafted" into new positions, superficially resembling the disruption of pack-ice on polar seas during spring thaws on Earth. The size and geometry of these features suggest that motion was enabled by ice-crusted water or soft ice close to the surface at the time of disruption.
