Lakes of Liquid Methane in Titan.

Radar imaging data from the Cassini flyby confirmed the existence of oceans and lakes of liquid methane on Saturn’s moon Titan:

The lakes, darker than the surrounding terrain, are emphasized here by tinting regions of low backscatter in blue. Radar-brighter regions are shown in tan. The strip of radar imagery is foreshortened to simulate an oblique view of the highest latitude region, seen from a point to its west.
