Here Be Dragons Pt V
Enceladus' core and behaviour can be modelled with a central singularity of 10^12 kg. This mass is typical for a primordial singularity. This object consumes only 2.8 kg per year and generates 10^9 watts of radiation. Water and other molecules near this centre are heated to a plasma. Electrons are stripped from atoms, and the resulting ions are drawn into circular orbits. The resulting current generates a magnetic field with the "positive" pole in the South.
Electrons and positively charged ions spiral along magnetic field lines to form bipolar jets, the classic sign of a singularity. The Northern jet is composed of electrons which are absorbed by the moon's interior. More energetic ions of the Southern jet penetrate these layers to warm the South Pole. Escaping ions spiral into space, exactly as observed by Cassini.
Unless Saturn's Rings are replenished, they would decay within 100 million years. Then we would face the anthropic question of why they exist in the right time for humans to view them. Thanks to the Cassini spacecraft, we have witnessed the E Ring being resuppllied from a moon. This observation suggests that similiar processes maintain the rings indefinitely.
Saturn and her Rings have long been objects of wonder and mystery. The processes that build moons and planets have been going on for billions of years. Humans have yet to understand what is before their eyes and beneath their feet. There is more to this solar system than meets the eye.
