These two images of Saturn show the entire south polar region. Earth-like storm patterns seem to be powering this vortex. These images were taken in the near-infrared on May 11, 2007, from a distance of 258,500 miles. From this distance, the resolution is 128 miles per pixel. The lower image represents a near-infrared wavelength seven times the reddest wavelength visible to the human eye. At this wavelength, the planet's own heat produces an internal glow against which clouds deep within Saturn are seen in silhouette. Thus, dark areas represent thick clouds while bright areas represent clearings in the clouds. The upper image shows the polar region in false color, with red, green and blue depicting the appearance of the pole in three different near-infrared colors.| Discovery Space Video |
