Liquid lakes on Titan,Cassini radar image. It is thought that the blue/black areas are lakes of liquid methane. They were found on Titan,the largest moon of Saturn. This image was obtained on 22 July 2006. The strip of land seen here is about 140 kilometres across. Titan has a thick atmosphere of nitrogen,making it difficult to see surface features,so mapping of Titan is being carried out using infrared and radar sensors. Previous evidence of liquid lakes was obtained by the Huygens probe that landed on Titan on 14 January 2005 | |
