Enceladus' geysers could have delivered sodium from its underground ocean and into Saturn's E ring
The Cassini spacecraft has found what may be the strongest evidence yet that Saturn’s tiny moon Enceladus has an ocean beneath its icy surface. If the liquid water finding is confirmed, it would suggest that the moon may be one of the most promising places in the solar system to search for signs of past or present extraterrestrial life.
