Source of mysterious deep space radio wave discovered for the first time

'Fast radio bursts', discovered only a decade ago, were found likely coming from dwarf galaxy about 3bn light years from Earth but cause remains uncertain

A mysterious type of radio wave from deep space, discovered only a decade ago, has been traced to a precise source for the first time, astronomers said on Wednesday.

So-called fast radio bursts (FRBs) picked up in 2016 by a telescope in New Mexico likely emanated from a dwarf galaxy some 3bn light years from Earth, the scientists reported in the journal Nature.
