This image shows some of the methane and/or ethane lakes found near the South Pole of Saturn's largest moon, Titan. This view, created with radar data from the Cassini spacecraft, has been artificially colorized; liquid methane/ethane is shown in blue, areas of "dry land" are brown. The lakes in this scene are about 8 km (5 miles) across.
