Saturn’s moon Mimas earned the nickname “Death Star Moon” because of one enormous crater called Herschel. With steep walls and a central peak, it looks exactly like the superlaser dish from Star Wars.

Saturn's moons Mimas (right) and Janus appear to hang silently in space as they orbit their ringed parent planet in this stunning photo from NASA's Cassini spacecraft at Saturn. The outer edge of ...

Recent studies, including research from ScienceDirect, suggest that Saturn’s moon Mimas, known as the “Death Star” moon for its iconic crater, may hide a secret ocean beneath its icy surface. While ...

Saturn’s “Death Star”-like moon Mimas may have a boiling ocean under its icy shell. The moon pitted with craters—including a very large one, giving it its nickname—may appear to be geologically dead, ...

The outer planets of the Solar System are swarmed by ice-wrapped moons. Some of these, such as Saturn’s moon Enceladus, are known to have oceans of liquid water between the ice shell and the rocky ...

Tidal migration – gradual outward movement of a moon due to gravitational interactions with its parent planet Axial precession – the slow wobble of a planet's rotational axis, which can fall in and ...

Saturn's moon Mimas, imaged by the Cassini spacecraft. A new study shows how such small ice moons could sustain a liquid ocean beneath an icy shell, and how that could give rise to surface features.
