This is a photo of Saturn’s moon Enceladus – a dynamic ice world. Its surface shifts on geologic timescales, with vast ice sheets spreading and crashing like tectonic plates. Cryovolcanoes (which is a real term that I did not make up) shoot geysers of water out into space.
Recent readings taken by the Cassini spacecraft suggest that Enceladus has a rocky core and liquid oceans beneath the icy surface.
This picture was taken as Cassini was speeding away from Enceladus in 2008, after skimming just 15 miles above its surface.
