The Coastlines of Titan

NASA's Cassini spacecraft made its 31st radar mapping pass of Titan, Saturn's giant moon, and produced the startling image of a coastline with bays, channels, islands, and so forth that could well have been taken of Earth. The "water" is an inhospitable mix of methane and ethane, but the similarity of processes at work on two totally different worlds is amazing. See the title link above for the image.
