Hi,
I'm going to chime in on the heating issue, since I beat the heck out of
this problem once in a planetary science course once.
The tidal heating of Jovian moons is caused by a kind of "argument" between
two factors. Each moon wants to orient itself (by matching its spin to
it's orbital pe

I love this topic.
Europa places the same face to Jupiter all of the time, as do most
satellites. I guess that it's the tidal heating that eventually
dissipates the rotational energy. I don't know of any other mechanism.
Jupiter doesn't continually flex Europa as in the balloon analogy

Thought you all might find this interesting...
I've taken the closest close-up photo of Europa's
surface I could find and superimposed an aerial
photo of the Washington Monument and surrounding
area that's at just about the same scale:

heating"
Good examples, Michael. If you want another example of how
tidal friction might affect heating of Europa's silicate mantle and
possible Fe-Ni core, just look at the images of Io, the nearest
neighbor and most volcanically active feature in our solar
sys
