Scientists find dense ring around dwarf planet, but can't quite explain why it's there
CBSN
New telescope data has revealed that a dwarf planet in the outer reaches of the solar system has a dense ring around it, leaving scientists and astronomers confused as to why.
Scientists at the European Space Agency announced Wednesday that data and observations of the planet Quaoar which was collected between 2018 and 2021 —from ground-based telescopes, and the space-based telescope Cheops — led them to the discovery.
The ESA disclosed that Quaoar crossed in front of a succession of distant stars, blocking their light as it passed, in an event called an occultation. When the planet blocked that light, scientists were able to see its ring.
