Story summary

Researchers say Saturn's moon Mimas may harbor a young subsurface ocean beneath its icy crust.
Gravitational interactions with Saturn altered Mimas' orbit and generated heat that could melt ice into water.
The ocean, if present, may have formed in the last 10 to 15 million years, according to models.
The Herschel crater's formation is cited as evidence that Mimas was near melting during that event.
