Now scientists believe that they may have spotted the first signs that the seas of Titan share another feature common to Earth's oceans. Glints of light picked up from the surface by NASA's Cassini spacecraft suggest that Titan's hydrocarbon oceans may also produce their own waves and ripples, albeit on a much smaller scale.

"Titan may be beginning to stir," said planetary scientist Ralph Lorenz. "Oceanography is no longer just an Earth science."
