xplanation: Looping through the Jovian system in the late 1990s, the Galileo spacecraft recorded stunning views of Europa and uncovered evidence that the moon's icy surface likely hides a deep, global ocean. Galileo's Europa image data has been remastered here, with improved calibrations to produce a color image approximating what the human eye might see. Europa's long curving fractures hint at the subsurface liquid water. The tidal flexing the large moon experiences in its elliptical orbit around Jupiter supplies the energy to keep the ocean liquid. But more tantalizing is the possibility that even in the absence of sunlight that process could also supply the energy to support life, making Europa one of the best places to look for life beyond Earth. What kind of life could thrive in a deep, dark, subsurface ocean? Consider planet Earth's own extreme shrimp.

Very cool! Those lines look at little like fungal hyphae (not inferring anything - just an observation).

It’s very likely that the subsurface ocean of Europa contains a lot of sulfur, making life within it impossible. Furthermore, whatever life would otherwise exist would be like Earth’s extremophiles, which did not evolve on their own but instead adapted to those conditions. Sorry to be such a Debby Downer.

Maybe my example was bad, after all, sulfur doesn’t make after life impossible...

Relatively impossible works.
