San Francisco – September 10, 2018 – Breakthrough Listen – the astronomical program searching for signs of intelligent life in the Universe – has applied machine learning techniques to detect 72 new fast radio bursts (FRBs) emanating from the "repeater" FRB 121102. Fast radio bursts, or FRBs, are bright pulses of radio emission, just milliseconds in duration, thought to originate from distant galaxies. Most FRBs have been witnessed during just a single outburst. In contrast, FRB 121102 is the only one to date known to emit repeated bursts, including 21 detected during Breakthrough Listen observations made in 2017 with the Green Bank Telescope (GBT) in West Virginia. The source and mechanism of FRBs are still mysterious. Previous studies have shown that the bursts from 121102 are emanating from a galaxy 3 billion light years from Earth, but the nature of the object emitting them is still unknown. Theories range from highly magnetized neutron stars, blasted by gas streams near to a supermassive black hole, to suggestions that the burst properties are consistent with signatures of technology developed by an advanced civilization.
