First fast radio burst traced to old, dead, elliptical galaxy without young, active stars.

Astronomers previously thought all FRBs were generated by magnetars formed through the explosions of very young, massive stars.

New observational evidence hints that the origins of these mysterious cosmic events might be more diverse than previously thought.

In 2022 , an international team of astronomers detected an FRB , which emanated from a tight cluster of stars on the edge of Messier 81 (M81), a spiral galaxy located about 12 million light years from Earth .

Out of the nearly 100 FRBs that have been pinpointed to a galaxy so far, most have likely originated from magnetars, which are formed through core-collapse supernovae.

Astrophysicists posit FRB 20240209A 's origin might be similar to the FRB found in M81 .
