On the Cover: A rare storm rages across the face of Saturn as seen by the Hubble Space Telescope. The white, arrowhead-shaped feature is about as big across (12,700 kilometers or 7,900 miles) as Earth. The winds at the storm's latitude blow at about 1,600 kilometers (990 miles) per hour. HST has been watching the storm since its discovery in September 1994. Flyby spacecraft such as the Voyagers can't give us such repeated coverage, which enhances the value of the HST data. This image was taken on December 1, 1994, when Saturn was 1,455 million kilometers (904 million miles) from Earth. Reta Beebe, D. Gilmore, L. Bergeron and NASA
