Shoreline on Titan?
This Synthetic Aperture Radar image of the surface of Saturn's moon Titan was obtained by the Cassini spacecraft on Sept. 7, 2005. The bright, rough region on the left side of the image seems to be topographically high terrain that is cut by channels and bays.
The boundary of the bright (rough) region and the dark (smooth) region appears to be a shoreline. The patterns in the dark area indicate that it may once have been flooded, with the liquid having at least partially receded.
The image is 175 kilometers high and 330 kilometers wide (109 miles by 205 miles), and is located at 66 degrees south latitude, 356 degrees west longitude in the southern hemisphere of Titan.
