Titan's dunes form the same way as Earth's

The mountains of East Xanadu rise high above the windswept plains and dunes of Shangri-La. This fantastical landscape isn’t found in a scene from a Hollywood movie, or even a desert on Earth, but on Titan, Saturn’s largest moon. New research looking at the surface topography of Titan — more than a billion kilometers from Earth — reveals it has a lot in common with our planet. The work, published in the Journal of Geophysical Research: Planets, shows that the dunes likely formed in a process that’s analogous to how dunes form on Earth — through weathering, erosion and deposition.
