Nasa probe finds the mile-high dunes of Saturn's moon Titan are eerily similar to Earth's

Nasa probe finds the mile-high dunes of Saturn's moon Titan are eerily similar to Earth's: "Nasa's Cassini probe has found that the dunes on the surface of Saturn's moon Titan vary in shape just like dunes on Earth - and even look similar to deserts on our planet.

The similarities end there, of course - not only are the dunes on Titan 300 feet high and up to a mile wide, they're made of frozen hydrocarbons - chemicals found in crude oil - rather than sand. "
