Ocean discovered inside Saturn’s moon Mimas

Astronomers have discovered evidence of a subsurface ocean under the icy abyss of Saturn’s mini moon, Mimas, which resembles the Star Wars Death Star.

After using observations from NASA’s Cassini spacecraft and studying changes in Mimas‘s orbit, the French team shared on Wednesday that a secret ocean 12 to 18 miles beneath the frozen surface was more likely to be there than an assumed rocky core.
