The Canadian Hydrogen Intensity Mapping Experiment (CHIME) radio telescope has detected radio waves from outer space, identifying 8 new repeating signals. These Fast Radio Bursts (FRBs) last only a few milliseconds but can emit more energy than 500 million Suns. CHIME, equipped with four cylindrical reflectors and 256 antennas, continuously scans the sky for FRBs. A previous study published in Nature reported 13 FRBs, with only one repeating. Repeating signals tend to last longer than non-repeating ones.
