James Webb telescope pinpoints origin of brightest flash of radio light ever detected

SMRTR summary

Scientists traced the brightest fast radio burst (FRB) ever detected to a specific region in galaxy NGC 4141, 130 million light-years away, using the James Webb Space Telescope. JWST's resolution revealed the burst likely originated from a red giant star, massive middle-aged star with a possible neutron star companion, or a magnetar. This discovery showcases JWST's capability to study individual stars associated with FRBs, potentially explaining these powerful cosmic signals.
