Look: Saturn's "Death Star" moon might have an ocean beneath its surface

It could redefine what it means to be an ocean world.

Meet Mimas, the smallest of Saturn’s eight major moons.

Its dominant crater makes it look a bit like the infamous Death Star from Star Wars.

Originally, researchers thought Mimas was frozen to the core.

But a new report in the journal Icarus reveals that this moon’s external layer might just be a cover for an inner ocean.
