Fast radio bursts (FRBs) are puzzling phenomena because their details are so difficult to resolve, and observations to date have been inconsistent. Astronomers added another piece to the puzzle with the detection of an FRB that seems to originate in a dead galaxy that is no longer producing new stars, according to a new paper published in The Astrophysical Journal Letters, along with a related paper on the event from scientists at Northwestern University. As we've reported previously, FRBs involve a sudden blast of radio-frequency radiation that lasts just a few microseconds.
