本期内容：
Something is happening out there, and astronomers 2 sure wish they knew what it was. For the last several years, they have been teased and baffled by mysterious bursts of radio waves from the distant universe: pops of low-frequency radiation, emitting more energy than the sun does in a day, that occur randomly 3 and disappear immediately. Nobody knows when these "fast radio bursts," or F.R.B.s, will occur, or where exactly in the cosmos 4 they are occurring.
