Blue Ring Around Uranus

ZedNaught writes "The BBC is reporting that 'astronomers have discovered that the planet Uranus has a blue ring - only the second found in the Solar System. Like the blue ring of Saturn, it probably owes its existence to an accompanying small moon.' According to the April issue of Science, the blue ring is one of two new outer rings recently discovered around Uranus using the infrared Keck adaptive optics system. The rings are blue and red like Saturn's E and G rings. The blue ring around Saturn hosts the moon Enceladus while the Uranus ring contains the moon Mab."

moon disintegrating

Quite interesting... Uranus' moon is part of the ring - the particles are hitting it - and the moon is slowly disintegrating. Wonder how long it will take for the moon to completely dissolve into the ring.
