Enceladus Worth Another Look

A strange "hot spot" at the south polar region of Enceladus has scientists postulating all sorts of theories, but none that explains why it's almost 300 degrees warmer there than it should be.
The Cassini spacecraft discovered the unusual anomaly during its third close pass of the Saturnian moon.

Whatever is causing the strange surface formations is definitely worth a closer inspection. It's very possible a liquid ocean could exist beneath the frozen surface of Enceladus much as scientists think exists beneath the surface of Europa.
Just my own personal theory...
