The more we explore the outer solar system with probes like the Cassini spacecraft, the cooler things we discover. This week planetary scientists working with data from that spacecraft announced that theres a good chance Saturns moon Titan has a layer of liquid water hidden beneath that desolate icy surface.
The discovery came from the study of tides on Titan. This moon is squeezed and stretched as it orbits Saturn, and that is bound to cause some heating in the core. Its also a shape-changing process.
