Haven't found an official press release on this but Yahoo has an article up about a few newly discovered rings of Uranus:
http://news.yahoo.com/s/ap/20051222/ap_on_sc/uranus_rings These rings were found between the Epsilon ring and Miranda's orbit. One apparently was found at around 97,000 km, near the orbit of Mab, suggesting that Mab supplies material for the ring. These rings are apparently quite faint, probably why VGR2 missed them. -------------------- &@^^!% Jim! I'm a geologist, not a physicist!

--- Before this discovery, the only known blue ring was Saturn's E-ring. It also has a moon orbiting at its heart – Enceladus - which spews out water vapour to generate the E-ring. Mab is surely too small to sustain similar activity, being only 15 kilometres across compared to 500 km for Enceladus. Instead meteorite impacts probably chip ice off the frozen surface to feed the ring. --- Illustration: -------------------- - blue_scape / Nico -
