High Quality Content by WIKIPEDIA articles! Xanadu (often called "Xanadu Regio", though this is not its official name) is a highly reflective area on the leading hemisphere of Saturn's moon Titan. Its name comes from Xanadu, the legendary palace described in Samuel Taylor Coleridge's poem Kubla Khan. 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. Preliminary observations indicate that Xanadu is a plateau-like region of highly reflective water ice, contrasting somewhat with the darker lower regions. These in turn seem to contrast quite sharply with the very dark maria, which were once believed to be seas of liquid hydrocarbons, but are now thought to be plains.
