Xanadu is a highly reflective area on the leading hemisphere of Saturn's moon Titan. Its name comes from an alternate transcription of Shangdu, the summer capital of the Yuan Dynasty established by Kublai Khan and made famous by Samuel Taylor Coleridge. The feature was first identified in 1994 by astronomers using the Hubble Space Telescope at infrared wavelengths, and has recently been imaged in more detail by the Cassini space probe. Xanadu is about the size of Australia. (wikipedia entry)
A albedo feature is an area which shows a contrast in brightness or darkness (albedo) with adjacent areas. On Titan they are named after sacred or enchanted places, paradise, or celestial realms from legends, myths, stories, and poems of cultures from around the world.
