Ganymede: A 'Club Sandwich' of Oceans & Ice?

Ganymede May Harbor 'Club Sandwich' of Oceans and Ice

The largest moon in our solar system, a companion to Jupiter named Ganymede, might have ice and oceans stacked up in several layers like a club sandwich, according to new NASA-funded research that models the moon's makeup.

Previously, the moon was thought to harbor a thick ocean sandwiched between just two layers of ice, one on top and one on bottom.

Europa was always supposed to be the "prize". I guess if Jupiter had become a star, we'd have a mini system orbiting another star.

Possibly, but irrelevant, Jupiter was never anywhere close to being a star. Had it accumulated enough mass to get even close the Galilean moons would probably have been unable to form anyway.

Is "club sandwich" a scientific term?

Sure seems water/ice is pretty common, at least in our solar system, and presumably throughout the galaxy as well. I would say that alone greatly raises the chances for life elsewhere.
