Europa contains a vast liquid water ocean beneath its icy crust. The moon is heated from within — tidal interactions with its parent gas giant generates the energy needed to maintain the liquid ocean — while the icy crust shields the ocean against the high-radiation space environment. The moon also has an active surface layer where the ocean interacts with the surface, producing tell-tail compounds such as magnesium sulfate. Calculations have also shown that there is likely enough oxygen cycling in the water to support a huge hypothetical biomass.
