FAST RADIO BURST PINPOINTED

The home of a fast radio burst (FRB) has been located for the first time – in a dwarf galaxy three billion lightyears away. FRBs are highly energetic but short-lived radio pulses, though what causes them remains a mystery. This burst, FRB 121102, is unique in that it was the only known FRB to repeatedly erupt. This allowed scientists to pinpoint its location. It seems the burst came from outside our Galaxy, rather than within.
