James Webb pinpoints most distant fast radio burst ever seen

Astronomers detected FRB 20240304B, the most distant fast radio burst yet, originating more than 10 billion light-years away from a time when the universe was about 3 billion years old. Using JWST, they identified the host galaxy, which is smaller than expected, metal-poor and forming many stars. The finding more than doubles the previous distance record for FRBs.

• FRB 20240304B traveled more than 10 billion light-years
• Host galaxy redshift measured at about 2.15
• Host galaxy is metal-poor and actively forming stars
• Previous FRB distance record more than doubled
