Newly discovered rings and moons of Uranus
Newly discovered rings and moons of Uranus This pair of composite images from the Hubble Space Telescope shows newly discovered rings around Uranus. The outermost of the two rings (R/2003 U1) is thought to be replenished by dust tossed off of a newly discovered moon, named Mab, which shares an orbit with the ring. Mab is visible as a bright streak at the top of the outer ring. NASA, ESA, and M. Showalter (SETI Institute)
