Mysterious Cosmic Radio Bursts Found To Repeat

"Astronomers for the first time have detected repeating short bursts of radio waves from an enigmatic source that is likely located well beyond the edge of our Milky Way galaxy. The findings indicate that these 'fast radio bursts' come from an extremely powerful object which occasionally produces multiple bursts in under a minute. Prior to this discovery all previously detected fast radio bursts have appeared to be one-off events."
