Scientists have discovered what appear to be sea-size bodies of liquid, probably methane or ethane, on the surface of Saturn's largest moon, including one about as big as Montana.Cassini's camera last month spied a large, irregular feature stretching 680 miles long with a surface area similar to Montana's, or to Asia's landlocked Caspian Sea. Its radar instrument swept over the feature's northern tip and determined that it likely contains liquid methane or ethane because of its smooth appearance.
The spacecraft also discerned another body one-fifth the size of Titan's "Caspian Sea." With a surface area of about 46,000 square miles, it is larger than Lakes Superior and Ontario combined, scientists said.
