Titan's surface. Cassini space probe infrared image of Titan,Saturn's largest moon. The inset picture (upper left) shows the intended landing place for the Huygens probe that will be released in December 2004. The colours represent the three wavelengths of infrared light observed to create this picture. Green shows the atmosphere,and the green-fringed white area at bottom is a cloud of methane over Titan's South Pole. The darker areas at top are surface features. Titan consists of ice and rock,with a thick atmosphere that is mostly nitrogen. Its diameter is over 120,000 kilometres | |
