Blue Ring Around Uranus

Posted by ryuzaki0 on from the too-many-hours-looking-through-a-telescope dept.

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."

    A blue ring is not as bad as some of the coffee rings that my Dad leaves on the countertop when he visits.

    My doctor gave me a very effective cream for this condition..

    You just smear it on the optics of the telescope and voila, no more rings!
