Images: Mysterious aurora, mighty storms on Saturn

Here is a side-by-side view of the north (left) and south (right) poles of Saturn. The north pole is covered by a cyclone that reaches 7,500 miles from the pole and is bordered by the hexagon.

There's an even larger cyclone at the south pole of Saturn. This one extends about 9,000 miles from the pole.
