‘Waves’ detected on Titan’s lakes http://www.bbc.co.uk/news/science-environment-26622586
Titan is a strange, looking-glass version of Earth with a substantial atmosphere and a seasonal cycle. Wind and rain shape the surface to form river channels, seas, dunes and shorelines.
But much of what’s familiar is also turned sideways: the moon’s mountains and dune fields are made of ice, rather than rock or sand, and liquid hydrocarbons take up many of the roles played by water on Earth.
However, these seas are filled not with water, but with hydrocarbons like methane and ethane.
These exist in their liquid state on Titan, where the surface temperature averages about -180C.
