With the use of seven telescopes spread across South America, observers have confirmed the unlikely discovery of a double ring surrounding the minor planet Chariklo, which holds orbit between Saturn and Uranus. Previously rings have only been found around giant planets, the most dramatic of which, Saturn, shines easily visible to the naked eye in the night sky.
