For the first time, scientists have tracked the source of a “fast radio burst” – a fleeting explosion of radio waves which, in this case, came from a galaxy six billion light-years away.
The cause of the big flash, only the seventeenth ever detected, remains a puzzle, but spotting a host galaxy is a key moment in the study of such bursts.

Their findings are published in Nature.
Fast radio bursts last only milliseconds but in that moment, whatever makes them blasts as much energy into space – in the form of radio waves – as our Sun emits in days or even weeks.
