Back Interiors of Ganymede and Europa

Interiors of Ganymede and Europa

Possible locations of liquid layers in the icy moons of Jupiter are shown here as a function of depth:
  1. completely frozen;
  2. three-layered structures impeding any contact between the liquid layer and the silicate floor;
  3. thick upper icy layer (>10 km) and a deep ocean;
  4. very thin upper icy layer (3-4 km).
Cases 3 and 4 are the most probable for Europa, and cases 1 and 2 for Ganymede and Callisto.
