Enceladus and the E-Ring
The Cassini probe has maneuvered itself to get a long look at Saturn's rings backlit by the sun. Ring experts have been looking forward to twelve hours of occultation to examine Saturn's seven known rings for fine structure. Check out this press release and more pictures from Saturn's neighborhood. Discoveries and achievements: - Enceladus's ice geysers contributing to the E-Ring (above) - An eighth ring co-orbiting with the moons Janus and Epimetheus - A color photo of the Earth and moon as seen from Saturn One overexposed backlit image shows the various rings, including the new H-Ring marked by the cross: The broad and diffuse ring seen above and below the other rings is the outermost E-Ring. Some of the mysterious missing spokes have turned up along the edge of the darker gap between the brightest rings.
