In this image released Thursday, Feb. 3, 2005, by NASA (news - web sites)/JPL, a mosaic of 35 individual infrared exposures made on Feb. 4, 2004, at the W.M. Keck I Observatory, Mauna Kea, Hawaii, shows what scientists say are the sharpest views of Saturn's temperature emissions ever taken from the ground. The prominent hot spot at the bottom of the image is right at Saturn's south pole. The warming of the southern hemisphere was expected, as Saturn was just past southern summer solstice, but the abrupt changes in temperature with latitude were not expected. A small section of the ring image is missing because of incomplete mosaic coverage during the observing sequence. (AP Photo/NASA/JPL)
