Astronomers detect a fast radio burst from an ancient galaxy, challenging previous theories on FRB origins.

Astronomers have detected a fast radio burst (FRB) from an ancient, dead galaxy, challenging the theory that FRBs originate only from young, star-forming galaxies. FRB 20240209A was found by the Canadian Hydrogen Intensity Mapping Experiment (CHIME) near the outskirts of an 11.3-billion-year-old galaxy, 2 billion light-years from Earth. This discovery suggests that FRBs could originate from older systems and raises new questions about their formation.
