Gravity measurements confirm subsurface ocean on Enceladus
Pasadena CA (SPX) Apr 04, 2014 - In 2005, NASA's Cassini spacecraft sent pictures back to Earth depicting an icy Saturnian moon spewing water vapor and ice from fractures, known as "tiger stripes," in its frozen surface. It was big news that tiny Enceladus-a mere 500 kilometers in diameter-was such an active place. Since then, scientists have hypothesized that a large reservoir of water lies beneath that icy surface, poss ... more
