Southern Saturn from Cassini

What happens to Saturn's pervasive clouds at its South Pole? Visible in this infrared image of Saturn are bright bands, dark belts, and a dark spot right over the South Pole. The robot Cassini spacecraft, currently orbiting Saturn, took this image last month. Saturn's atmosphere is about 75 percent hydrogen, 25 percent helium, and small amounts of heavier compounds including water vapor, methane, and ammonia.
