Galileo's Wild Ride

On the Cover: A familiar jovian feature appears at the Great White Spot in this false-color rendition created from data gathered by the Galileo spacecraft. Here the colors indicate cloud heights, not the composition of the particles that give Jupiter's atmosphere its predominant red, white and orange tints. In this image, white indicates high, thick clouds. For example, the while areas near the north edge of the gigantic cyclone are little thunderstorms. In natural light, the Great Red Spot appears red because of a high haze swirling at the top of the storm. So here, it is white. New products such as this are giving scientists new ways of learning about Jupiter.
