Ligeia Mare, shown here in an artistically enhanced image from NASA's Cassini mission, is the second largest known body of liquid on Saturn's moon Titan. It is filled with liquid hydrocarbons, such as ethane and methane, and is one of the many seas and lakes that bejewel Titan's north polar region. Cassini has yet to observe waves on Ligeia Mare and will look again during its next encounter on May 23, 2013.
The image is a false-color mosaic of synthetic aperture radar images obtained by the Cassini spacecraft between February 2006 and April 2007. Features thought to be liquid are shown in blue and black and areas likely to be solid surface are tinted brown. Some areas with noisy data have been artistically enhanced.
