University of California - Los Angeles New research published in the journal Nature resolves decades of scientific controversy over the origin of the extremely energetic particles known as ultra-relativistic electrons in the Earth's near-space environment and is likely to influence our understanding of planetary magnetospheres throughout the universe. Discovering the processes that control the formation and ultimate loss of these electrons in the Van Allen radiation belts — the rings...

Several Key Discoveries During Van Allen Probes’ First Year
2013-09-01 07:49:38

redOrbit Staff & Wire Reports – Your Universe Online NASA’s twin Van Allen Probes entered their second year of service Friday having already provided a wealth of new information about the layers of energetic charged particles located above our planet. According to the US space agency, data collected by the probes since their August 30, 2012 launch has already led to “several significant discoveries” about the Van Allen radiation belts -- some of which came within the first...

Van Allen Probes Discover New Radiation Belt, Possibly Due To Solar Storm
2013-02-28 14:59:50

Lee Rannals for redOrbit.com — Your Universe Online NASA announced that its Van Allen Probes have led to a revision of a 50-year-old theory about the Earth's radiation belts. The Van Allen radiation belts surrounding Earth were thought to be just two giant swaths of radiation, first discovered in 1958. More than a half-century later, NASA launched twin probes (August 30, 2012) to create a detailed map of the region and catalogue a variety of energies and particles in these...

Van Allen Radiation Belt -- The Van Allen radiation belt is a torus of energetic charged particles around Earth, trapped by Earth's magnetic field. The presence of a radiation belt had been theorized prior to the Space Age and the belt's presence was confirmed by the Explorer I on January 31, 1958 and Explorer III missions, under Doctor James Van Allen. The trapped radiation was first mapped out by Explorer IV and Pioneer III. Qualitatively, it is useful to view this belt as consisting...
