Global Ocean Suspected on Saturn's Enceladus
Explanation: Do some surface features on Enceladus roll like a
conveyor belt? A leading interpretation of
images taken of Saturn's
most explosive moon indicate that they do. This form of asymmetric
tectonic activity, very unusual on Earth, likely holds clues to the internal structure of
Enceladus, which may contain subsurface seas where
life might be able to develop.
Pictured above is a composite of 28 images taken by the robotic
Cassini spacecraft in 2008 just after swooping by the
ice-spewing orb. Inspection of these images show clear
tectonic displacements where large portions of the surface all appear to
move all in one direction. On the image right appears one of the most prominent tectonic divides:
Labtayt Sulci, a canyon about one kilometer deep. The small magnitude of Enceladus' wobble as it orbits Saturn might indicate damping by a globally extending
underground ocean layer.

Global ocean in Saturno's Moon Enceladus.
It is very interesting. Enceladus can to have
life of some form, Elemental life perhaps.

Hahaha! My 9 years old daughter looked at this picture and said "look! there's water in there!"
I don't know how long did it take for NASA to know it has water in it?
She can't read English by the way.
And this is a true story. Children are amazing.

A really creative person might want to equip their pool table with 15 planet or moon balls and a sun queue to knock into one of the six "black hole" pockets. It would be great if "event horizons" near their edges might even help those
slightly erroneous shots.

No telling what a star chart felt and "relativity" bumpers might lend to the effect. Let alone the atmosphere created by an astronomy-minded stained glass light fixture/planetarium combo. What else could the astronomer/ pool player want after a hard day at the office?
A
UFO on "Enceladus" rocks?

Who ever would have imagined great balls of water flying throughout space?

With some suspicion Pluto also might have had a planet wide ocean.
