Astronomers are having an easier time finding fast radio bursts as of late, and that now includes the first regular pattern for those bursts. A research team from MIT and elsewhere has discovered that something 500 million light-years away is routinely producing four days of seemingly random but frantic bursts, followed by 12 days of silence — something that happened consistently for 500 days of study.

Sure enough, astronomers have discovered even more of those mysterious fast radio bursts from outside the Milky Way galaxy. Scientists using the Canadian Hydrogen Intensity Mapping Experiment (CHIME) telescope have detected 13 different radio bursts, including six repeat bursts from the same location in a galaxy 1.5 billion light years away. Each of those bursts represents about 25 million times more energy than the Sun, and they were collected at the lowest frequencies yet (400MHz to 800MHz).
