PASADENA, Calif., June 24 (UPI) -- Scientists working on the U.S. space agency's Cassini spacecraft's mission say Saturn's moon Enceladus might have an underground ocean.
The researchers said they have, for the first time, detected sodium salts in Saturn's outermost ring. That finding, they said, suggests Enceladus, which primarily replenishes the ring with material from discharging jets, could harbor a reservoir of liquid water -- perhaps an ocean -- beneath its surface.
