But only one of these sources of radio energy has erupted a couple of times - a so-called burster called FRB 121102. They were also able to detect the radio bursts at a higher frequency than ever. However, the most powerful of these flares ever observed has been four orders of magnitude below FRB 121102. The researchers are eager to use a number of observatories with new radio telescopes coming online to observe more fast radio bursts. The big mystery today, Hessels says, is what causes these repeating fast radio bursts.
