Hydrocarbon Seas on Titan Cassini used its onboard radar to record these false-color views of the region near Titan’s north pole. (a) The dark regions show where the surface does not reflect radio waves at all, which leads to the interpretation that these are flat lakes (presumably filled with liquid methane and ethane). (b) Lake Ligeia Mare is one of the larger lakes and is about the size of Lake Superior (about 350 miles wide). In this high resolution image, many tributaries can be seen around the lake’s perimeter.
