The meaning of VAN ALLEN BELT is a belt of intense radiation in the magnetosphere composed of energetic charged particles trapped by the earth's magnetic field; also : a similar belt surrounding another planet.
In the new research, UCLA space scientists have revealed that the extremely energetic particles that made up the third ring, known as ultra-relativistic electrons, are driven by very different physics than typically observed Van Allen radiation belt particles. How unusual ring of radiation formed bet...
