The Tempest

[chani]

There's a huge storm going on on Saturn. Cassini spacecraft spotted it on the 11th of December. The storm area is approximately 8,000 kilometers (5,000 miles) across, or two thirds the diameter of Earth! A movie taken by Cassini's camera over a three-hour period reveals winds around Saturn's south pole blowing clockwise at 550 kilometers (350 miles) per hour.
