Results from the February 20th flyby of the robot spacecraft Galileo past Europa now clearly indicate that either large bodies of water or slush exist under a relatively thin ice sheet covering the moon's surface , at least in some regions. Areas on the surface are marked by very few craters, indicating that water flowed there in the time since most craters formed.
