Oh Titan, you ARE the most interesting moon out there, aren't
you?? If only we could convince Saturn to let us have a better
look! Just a few weeks ago we were talking about the tropical
oasis found on Titan, and now we're hearing something even more
exciting: below those methane lakes and pools is an ocean… of
normal water! They found it by watching the moon being squeezed
the closer it was to Saturn during its orbit… and then relaxing
as it moved further way. This squeezing can be measured, and
depending on how flexible it is, we can infer how a planet (or
moon) is deformed by tides. A completely solid world would be a
zero on this scale. A completely liquid one would be 1.5. The
team that conducted the Cassini study calculated a .6 for Titan.
Here's what one of the scientists said: "The density of Titan is
consistent with a body that is about 60% rock and 40% water. The
ocean must be fairly thick — a few hundred kilometers. And it
must lie relatively close to the surface — beginning no farther
down than 10
