Strange things happening to the rings of Uranus

The time for the rare views is right now, and a team of astronomers from UC Berkeley and the SETI Institute in Mountain View has seen some dramatic changes — some rings are growing brighter, at least one is fading away, and another is either new-formed or unexpectedly moving outward from the planet by thousands of miles.""
