Astronomers just spotted an extremely bright burst of radio waves emanating from within our own galaxy. The surprising observation could help us understand the mystery behind these enigmatic emissions, known as fast radio bursts.
Canadian scientists have detected 13 new fast radio bursts, those mysterious, split-second, high-energy pulses that reach us from unknown origins billions of light-years away. Intriguingly, one of these newly documented bursts is a repeater, becoming just the second-known repeating fast radio burst among the 60 documented so far.
Fast radio bursts, or FRBs, are a source of endless fascination. But despite a decade of observations, not all astronomers are sure that they’re real. A study out in Nature today, which reports the very first recurring FRB, is now causing lingering scepticism to evaporate.
