Hexagon on Saturn's North Pole

The Cassini spacecraft has sent images back of a weird, six-sided hexagon that covers the entire north pole of Saturn. The hexagon shape was first imaged by the Voyager 1 and 2 spacecrafts, and is 25,000 km across -- a size that could hold about four Earths -- and 100 km deep. The hexagon has a system of clouds that is whipping around in it, as can seen in movies made from the Cassini images.
