Hubble Finds Rings and Moons Around Uranus

If you have not thought about Uranus in a while, perhaps it's time you should. SETI scientists working with the Hubble Space Telescope, have spotted two additional rings and more than a dozen tiny new moons circling the mysterious blue world at the edge of our Solar System.
Scientists believe the newly discovered dust rings are being supplied with material by meteoroid collisions with an outer satellite now called Mab. This dust continues to spiral in and away from Uranus proper, slowly diminishing the ring itself until a new collision sends more material hurtling skyward. They believe the small moons will inevitably collide with each over the course of the next million years or so, creating more orbiting dust and debris.
