Astronomers have discovered fast-repeating radio bursts (FRBs) from a distant galaxy that shouldn’t produce such signals, leaving researchers puzzled. These FRBs, detected by the CHIME telescope and imaged with Gemini North, originated from an ancient elliptical galaxy 2 billion light-years away. Unlike typical sources of FRBs, which are young neutron stars forming quickly, this dead galaxy lacks those active stars. This finding challenges existing theories about how FRBs are produced. Hundreds of FRB locations have been pinpointed since their first detection in 2007, with most near active stars, but this outlier is far from any star formation. The discovery could help scientists better understand the universe’s structure and history between distant galaxies and our Milky Way.
