Lakes on Titan

Telescopes on-board the Cassini spacecraft orbiting Saturn has seen Sun-light glinting off a lake on the moon Titan - amazing!

But they are not lakes of water. At -180°C, it's far too cold for that. These are lakes of liquid hydrocarbons, such as methane, on a part of the moon dotted with many lake-shaped basins. When the Huygen's probe landed on Titan in January 2005 it took the image to the left.

One has to wonder - could there be primitive life on Titan, or is it simply far too cold?
