No methane lakes on Titan

Saturn's moon Titan is as dry as a bone over most of its surface, suggest new infrared images from Earth.

The work supports similar observations from the Cassini spacecraft, in orbit around the Ringed Planet. And it suggests previous radar studies from the ground - which hinted the giant moon was covered in liquid methane seas - were actually detecting signs of liquid that had long since vanished.

Well, maybe there aren't standing lakes, but there are definitely periods when liquid rains down onto the surface. We saw riverbeds, smooth rocks, and no impact scars. That seems pretty conclusive.
