FRB 180916 is only the second repeating fast radio burst to be traced back to its source galaxy.
This is the first time the location of a one-off fast radio burst has been detected.
A second-repeating radio signal, FRB 180814.J0422+73, was found to repeat six times from a distance of 1.5 billion light-years away.
Sky survey vastly expands the number of FRBs—radio signals produced by hugely energetic but unknown sources.
Fast radio bursts were recorded during a survey of the sky that began January 2017.
Scientists don't know what causes the weird signals.
Physicists discuss the latest discovery of 15 radio bursts coming from a galaxy three billion light years away.
Breakthrough Listen project observes 15 fast radio bursts coming from dwarf galaxy 3 billion light-years away.
Fast radio burst 150215 was detected in real-time with the Parkes radio telescope in Australia in 2015.
