This view of Titan taken on Feb. 25, 2007, reveals a giant lake-like feature in Titan's North Polar Region. It is approximately 1,100 kilometers (680 miles) long and has a surface area slightly smaller than that of Earth's largest lake, the Caspian Sea.

Cassini Extends Mapping of Titan's Surface

Cassini's radar eyes imaged additional regions near Titan's north pole during an April 26, 2007, flyby. The instrument imaged the area slightly north of a feature nicknamed the "black sea." The radar coverage crossed over four previous radar swaths to fill in more of the gaps in the coverage of Titan's north pole. On this flyby, Cassini's infrared spectrometer saw the lit and dark sides of Titan, looking for hot spots and lightning. The imaging cameras did global mapping and full-disk mosaics.
