Astronomers have discovered a fast radio burst (FRB) originating at the edge of an old galaxy, challenging prior assumptions that FRBs primarily arise from young, active galaxies' magnetars. This suggests that the source of some FRBs may lie beyond conventional explanations. The signal was detected by the Canadian Hydrogen Intensity Mapping Experiment (CHIME), which has already identified over 1,000 FRBs. This detection underscores the potential of CHIME's Outriggers to pinpoint FRB sources, marking a significant advancement in astronomical research and offering insight into the universe's complexities.
"The FRB origin story is far from boring, and certainly far from solved," says Wen-fai Fong, emphasizing the ongoing mysteries surrounding fast radio bursts.
Once CHIME can routinely locate FRBs, "it will be the next big game changer in the field," says Laura Spitler, highlighting the technological advancements in FRB research.
