Computer model explains sustained eruptions on icy Enceladus

> But Enceladus, which probably has an ocean underlying its icy
> surface, has somehow managed to sprout multiple fissures along its
> south pole. These "tiger stripes" have been erupting vapor and tiny
> frost particles continuously along their entire length for decades
> and probably much longer.
>
> "It's a puzzle to explain why the fissure system doesn't clog up with
> its own frost," Kite said. "And it's a puzzle to explain why the
> energy removed from the water table by evaporative cooling doesn't
> just ice things over."
>
> What's needed is an energy source to balance the evaporative cooling.
> "We think the energy source is a new mechanism of tidal dissipation
> that had not been previously considered," Kite said. Kite and
> Princeton's Allan Rubin present their findings the week of March 28
> in the Early edition of the Proceedings of the National Academy of
> Sciences.
