    Liquid seas exist on the surface of just two worlds in the Solar System: Earth and Saturn's moon Titan. Discovered by NASA's Cassini spacecraft about a decade ago, the hydrocarbon seas of Titan are more exotic, of course, as they exist in liquid form at temperatures around -180 degrees Celsius.
    Now, after the Cassini spacecraft has made a number of flybys of Titan, scientists assessing light and other radiation emanating from the moon's surface say they have a better handle on exactly what is in one of those seas. And to their surprise, they have found that the second largest lake on Titan, Ligeia Mare, is composed of nearly pure methane.
