Mimas’ heavily cratered surface (left) suggests a cold history, but its librations rule out a homogeneous interior. Rather, Mimas must have a rocky interior and outer hydrosphere, which could include a liquid ocean (Option A) or be fully frozen with an irregularly shaped core (Option B). An ocean provides a better fit to the phase of the libration but is difficult to reconcile with Mimas’ geology.

More evidence that Saturn’s moon Mimas is a stealth ocean world

A meteorite thin section under a microscope. Different colors represent different minerals, because light travels through them in different ways. The round mineral aggregates are chondrules, which are a major component in primitive meteorites.

Boudinage in brecciated dolostone rocks of the Panamint Range (Wildrose Area, Death Valley National Park). New research shows that periclase is stronger than bridgmanite in earth's lower mantle, analogous to boudins developing in rigid ("stronger") rocks among less competent ("weaker") rocks.
