#OMG: Astronomers investigate signals from a distant galaxy

Astronomers in Canada investigate the origin of mysterious radio signals from a distant galaxy that were picked up by a radio telescope. According to an investigation by the journal Nature, 13 rapid radio bursts (FRB) were detected, including a very unusual repetition signal from the same source, some 1,500 million light-years away. This phenomenon has only been reported once before by a different telescope. Ingrid Stairs, an astrophysicist at the University of British Columbia (UBC), said that "knowing there is someone else suggests that there could be more out there, and with more repeaters and more sources available for the study." He added that in that way "we could understand these cosmic enigmas, where they are from and what causes them". FRBs are short, bright flashes of radio waves. This cosmic phenomenon is one of the main astrophysical enigmas, but its nature has not yet been understood. The source comes from something with an extremely powerful magnetic field that produces a signal along the radio frequency band.
