Helium Summary: A recent fast radio burst (FRB 20240209A) originating from an ancient, non-star-forming galaxy challenges existing theories on the origins of these cosmic phenomena . Typically, FRBs are thought to originate from young, magnetized neutron stars (magnetars) in active galaxies.

However, this FRB's source, about 11.3 billion years old, defies that theory as it lacks young stars . Detected by the CHIME telescope, the signal comes from an elliptical galaxy located 2 billion light-years away in the constellation Ursa Minor . The research, published in Astrophysical Journal Letters, suggests diverse potential sources for FRBs beyond the previously presumed scenarios .
