On the Cover: The black rings of Uranus reveal subtle color differences in this computer-enhanced, false-color image generated from data returned by Voyager 2 during its January 1986 encounter with the planet. The bright epsilon ring appears as the neutrally colored line at the top. Moving down, toward Uranus, are the delta, gamma, and eta rings, here seen as bluish-green, with the beta and alpha rings in lighter tones. Below them are rings 4, 5 and 6 in pinkish shades. The faint pastel lines between the more defined rings may be traces of new rings discovered by Voyager 2. JPL / NASA
