NASA satellites aid study of relativistic particles

Science
May 29 (UPI) -- New data collected by NASA satellites suggest local acceleration explains most of the relativistic particles found in the Van Allen radiation belts circling Earth. After analyzing data collected by NASA's Van Allen Probes and the agency's THEMIS satellites, scientists determined electromagnetic waves called chorus waves are responsible for accelerating particles in the Van Allen belts to relativistic speeds. When recorded, the wave's pattern produces a chirping sound that recalls the chorus of a songbird. According to the new research, the waves steadily push ions and electrons found in the belt into higher and higher speeds. By developing models that better explain the propagation of high-energy particles inside the radiation belts, scientists can better predict space we...
