JWST reveals first observed changes in Chariklo's rings

An international team using the James Webb Space Telescope has detected that the two rings of the centaur Chariklo are changing over a few years: one is becoming more opaque, the other less. This is the first time ring changes have been observed on a small solar system body, providing new constraints on ring dynamics and evolution. The finding is based on JWST observations, but the underlying mechanisms remain uncertain.
