Tidal heating could power Saturn’s moon Enceladus for tens of millions to billions of years if its core is porous and unconsolidated, a new model suggests. The conclusion is based on 3D simulations of ...

Tidal currents flood and ebb with the tide, but their motion does not average to zero everywhere over a tidal cycle. The resulting net displacement of a water parcel gives rise to weak but persistent ...

A computer simulation shows how icy moon heats water in a porous rock core. This study also offers among others an answer to the long-standing question of where the energy that can support water in ...
