A slight, peculiar wobble exhibited by the moon and detected by astronomers could be the result of a liquid internal ocean, according to new research.
If this is the case, Mimas will join other Solar System moons such as Europa and Enceladus in the category of 'IWOWs' (interior water ocean worlds). But if so, it's an IWOW of a kind we've never seen before, expanding our understanding of what's possible.
"Because the surface of Mimas is heavily cratered, we thought it was just a frozen block of ice," says geophysicist Alyssa Rhoden of the Southwest Research Institute.
"IWOWs, such as Enceladus and Europa, tend to be fractured and show other signs of geologic activity. Turns out, Mimas' surface was tricking us, and our new understanding has greatly expanded the definition of a potentially habitable world in our Solar System and beyond."
Here on Earth, life mostly relies on sunlight to survive, but there are a few places where organisms can thrive in complete darkness.
At the bottom of the ocean is one of them, clustered around hydrothermal vents that release heat and nutrients from Earth's interior. Here, life relies not on photosynthesis, but on chemosynthesis, harnessing chemical reactions to synthesize food.

The Moon that resembles a Death Star is Saturn's Moon Mimas.
The Epic Secret is that it may be hiding a global ocean beneath its Death Star like shell.

Follow the water and you'll find life the old saying goes ... Water water every where.

I still believe the moon and a permanent base and/or orbiting station is the next key to space explorations

It could turn out to be an off-center core causing the wobble like they claim the moon has.
Of course, our moon has had sensor data showing water vapour clouds and the like, so maybe there is water under the surface too.
As a side thought, I read somewhere we have at least 3 times more water under the surface. So maybe...
For all we know, it could be that living under the ice on Europa is more hospitable than the surface of Mars.

Not an astrophysicist but isn't Saturn too far from Sol for anything Unfrozen?

I wonder if the earth at one time had an outer shell to it and something broke it and pieces of it fell into the water and created the continents.
Well, if scientists can dream stuff up, why can't I?

At least twice in Earth’s history, nearly the entire planet was encased in a sheet of snow and ice. These dramatic “Snowball Earth” events occurred in quick succession, somewhere around 700 million years ago, and evidence suggests that the consecutive global ice ages set the stage for the subsequent explosion of complex, multicellular life on Earth.

It would have to be like some of the moons of Jupiter. The water is liquid because of the crush and squeeze of tidal forces on the planet creating heat.
