In this composite image released by NASA, the northern polar region of Saturn showing both the aurora and underlying atmosphere, are seen at two different wavelengths of infrared light as captured by NASA's Cassini spacecraft. This image is a composite captured with Cassini's visual and infrared mapping spectrometer. The aurora image was taken in the near-infrared on Nov. 10, 2006, from a distance of 1,061,000 kilometers (659,000 miles), with a phase angle of 157 degrees and a sub-spacecraft planetocentric latitude of 52 degrees north. The image of the clouds was obtained by Cassini on June 15, 2008, from a distance of 602,000 kilometers (374,000 miles) and a sub-spacecraft planetocentric latitude of 73 degrees north.
