The Oldest Radio Burst and Chariklo's Rapidly Changing Rings

A new distance record has been set with the help of the JWST, spotting the distant (and therefore ancient) galaxy that produced an enigmatic fast radio burst or FURBY, detected by radio telescopes in 2024. This opens a new frontier for probing the early universe as those radio waves travel across and interact with galaxies, clusters, and the intergalactic medium before reaching us. Closer to home, new observations reveal baffling large-scale changes in the already baffling narrow rings around the small Centaur object Chariklo.
