The discovery is putting into question everything astronomers believed about ring systems.
Astronomers from the University of Sheffield discovered a new ring system around a dwarf planet on the edge of the Solar System, according to a
The astronomers spotted the ring system by using HiPERCAM - an extremely sensitive high-speed camera developed by scientists at the University of Sheffield, which is mounted on the world's largest optical telescope, the 10.4-meter diameter Gran Telescopio Canarias on La Palma.The rings cannot be seen directly in an image, so the discovery had to be made by observing an occultation when the light from a background star was blocked by Quaoar as it orbits the Sun.
