Two giant swaths of radiation, known as the Van Allen Belts, surrounding Earth were discovered in 1958. In 2012, observations from the Van Allen Probes showed that a third belt can sometimes appear. The radiation is shown here in yellow, with green representing the spaces between the belts. Credit: NASA/Van Allen Probes/Goddard Space Flight Center
Learn about this new result in a video by NASA Goddard Heliophysics Division. NASA presented these results at a press conference today. Tomorrow I will be on a Google Hangout with several of my colleagues at NASA Goddard. http://bit.ly/YzL5Mz Ask questions using #VanAllen
