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. The discovery on Mimas is a rarity, but the moon is not alone in its potentially life-friendly conditions. In addition to discovering Saturn's moons, the research also uncovered new information about the planet. So it was determined that Saturn's rings will disappear over time.
