Added 1 new A* page:A hexagonal storm 8,600 miles on a side surrounds the north pole of Saturn; heretofore that pole had been shrouded in night, so the storm could only be seen in rather blurry infrared photos taken by the orbiting Cassini probe; now, however, the Sun has reached the pole, and Cassini has been able to snap some vivid close-ups of the vortex at the center of the mysterious storm--a whirling hurricane perhaps some 1000 miles across:

You can compare those against the infrared Cassini photo I posted when I talked about the storm back in January. The reason for the hexagonal shape is still a mystery! Here's NASA's article on the new photos.
