The Weather Maps of Titan

Evidence of changing weather patterns in the skies over Titan's southern region are revealed in these false color images obtained by the Cassini spacecraft's visual infrared mapping spectrometer over two recent flybys of this largest of Saturn's satellites. In the first image (left), obtained on the Oct, 26, 2004 Titan flyby, from a distance of some 200,000 kilometers (124,300 miles), Titan's skies are cloud-free, except for a patch of clouds observed over the south pole near the bottom of the image. In contrast, the image on the right shows a recent view of this same area of Titan obtained seven weeks later on the second close Titan flyby on Dec. 13, 2004, from a distance of 225,000 kilometers (139,800 miles). This image clearly shows that several extensive patches of clouds have formed over temperate latitudes. The appearance of these clouds reveals the existence of weather. -- NASA Cassini Image: Spying Titan's Weather
