Science Daily  December 13, 2019 Scientists have known that electrons in Van Allen radiation belts that interact with ultralow frequency plasma waves accelerate to reach the speed of light. However, it has not been clear when or where these killer electrons start to accelerate. To gain more insight about the electrons an international team of researchers (Japan, USA – industry, University of Iowa, Russia) analyzed data generated on March 30, 2017, by the Arase satellite and Van Allen Probe. On one side of the Earth, the Van Allen Probe identified characteristic signs of an interaction between ultralow frequency waves and […]
