[FOX] Fast radio bursts (FRBs) are perhaps the most mysterious anomaly in space, with many having unknown origins. According to a new study, an FRB has been spotted coming from a galaxy 500 million light-years from Earth and it's repeating every 16 days.
And no one knows why.
Known as FRB 180916.J0158+65, this FRB sends out radio wave bursts for a period of four days, stops for a period of 12 days, then repeats itself. The initial 28 patterns were first observed between September 2018 and October 2019, according to a pre-published study. "We conclude that this is the first detected periodicity of any kind in an FRB source," the researchers wrote in the study.
