Here two great hurricanes can be seen spinning on Neptune's surface. This photo was taken in August 1989 by Voyager 2, the only spacecraft to travel to Neptune. The Great Dark Spot is seen to the north, while Great Spot 2, with its white center, is more to the south. The white clouds in between were nicknamed "The Scooter" by NASA. The storms were thought to be swirling masses of gases similar to hurricanes on Earth. But when Hubble turned its telescope on Neptune in 1994, the storms had disappeared.
