The international research team using the Canadian Hydrogen Intensity Mapping Experiment (CHIME) radio telescope, in Penticton, B.C., reports a repeating fast radio burst, only the second to be recorded, and one of 13 newly detected bursts. At least seven of these bursts were recorded at 400 megahertz – the lowest frequency recorded so far. Fast radio bursts are millisecond-duration, extragalactic radio flashes of unknown physical origin. Only one repeating fast radio burst had been observed previously, and the lowest radio frequency recorded previously was 700 megahertz.
