Coronal mass injection find could see ‘textbooks rewritten’
The Verge: NASA says it has made a discovery which will require “rewriting textbooks” after it found the two rings of charged particles surrounding the Earth - called Van Allen belts - were reconfigured by a coronal mass injection. Not only are the belts now believed to be more malleable, the mass injection revealed for the first time the formation of a third belt.

This may have been one of the causes of a third radiation belt that appeared around Earth a few days later. (Credit: NASA/SDO/AIA/Goddard Space Flight Center)
