A research published in Nature explains how they form the accelerated electrons in the radiation belts of Earth: the origin is the “chorus” caused by electromagnetic radio waves that oscillate at very low frequencies in the Van Allen. It confirmed the local acceleration theory. Image source: www.jpl.nasa.gov They are called ultrarelativistic electrons and move at
