Flip-Flopping Magnetic Fields Hint at a Solution for Puzzling Fast Radio Bursts From Space
Fast radio bursts — intense, milliseconds-long flashes of radio energy from outer space — have puzzled astronomers since they were first spotted in 2007. A single burst can emit as much energy in its brief life as the Sun does in a few days. The great majority of the short-lived pulses originate outside our Milky ...
