New gravity data from recent Cassini flybys of the giant planet suggest that Dione's crust floats on an ocean 62 miles below the surface, and may harbor microbial life.
A prior study demonstrated that Pluto's center is sufficiently warm to bolster a fluid water sea, and now we've discovered that it may be immense - no less than 100 km (62 miles) profound.
