Could Saturn’s moon Titan have an underground ocean?

Most all of this conjecture is a tortuous attempt to save the sacrosanct age of the solar system butifnot

I've seen comments other places where the assumption is that the Scientist, who should know enough to be more precise, meant "under ice ocean". Underground lakes are not uncommon on Earth. But a body of water big enough to be called an "ocean" would do strange things to whatever solid ground was on top of it. Although this is not frequently mentioned by the SETI guys, Jupiter generates HUGE amounts of radiation that effectively sterilze the surface of its moons every minute of every day. The desire for there to be an ocean of water under a sheet of ice is that several miles of ice might just barely provide enough insulation to prevent continuous sterilization of the "ocean". Thus there is a teeny-weeny outside chance that there is some pond scum growing next to the thermal vents. Rational, objective observers of course conclude that Europa is likely to be as dead as Mercury, which is also bathed in enough radiation to guarantee sterilization. mahuna
