Astronomers using a giant telescope atop a volcano have discovered a hot spot at the tip of Saturn's south pole. The infrared images captured by the Keck I telescope at the W.M. Keck Observatory atop Mauna Kea on the Big Island suggest a warm polar vortex &#151; a large-scale weather pattern likened to a jet stream on Earth that occurs in the upper atmosphere. It's the first such hot vortex ever discovered in the solar system.
