Rare discovery in space: Saturn's moon Mimas has an ocean. This discovery could change our understanding of life beyond Earth.
Dozens of moons orbit Saturn, but only a few have water on them. Previous research has suggested that there could be an ocean beneath the surface of Mima. In addition to discovering Saturn's moons, the research also uncovered new information about the planet itself. So it was determined that Saturn's rings will disappear over time. The age of the lunar ocean was determined through a detailed analysis of tidal interactions between Mimas and Saturn.
