(Newser) – NASA's radar detected evidence of huge seas—one of them larger than any of the Great Lakes—on the surface of Saturn's moon, Titan. Although the spacecraft, Cassini, cannot confirm that the dark images are liquid until passing over the area again as scheduled in May, scientists believe they are bodies of liquid ethane or methane gas.

One scientist predicted before Cassini's launch in 2004 that it would find oceans complete with waves, but the presence of any liquid would fulfill one of the mission's goals.
