Giant lake near Titan's north pole
Giant lake near Titan's north pole This view of the north pole of Titan taken on February 25, 2007 contains a large, dark feature with arcuate edges, very likely a giant lake like those seen by the RADAR instrument. The feature 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. NASA / JPL-Caltech / SSI
