Magnetic Fields Hold Clues to Fast Radio Bursts from Space

A new study published in Science highlights a rare repeating fast radio burst (FRB 20190520B) that produces radio bursts a few times an hour, occasionally at different radio frequencies. Using the five-hundred-meter Aperture Spherical Radio Telescope (FAST) in China, astronomers were able to identify and study this phenomenon, which has never stopped repeating. FRBs are powerful, millisecond-long radio bursts from space that produce as much energy during their brief existence as the Sun produces over a few days.
