Formation of unusual ring of radiation around Earth explained

Posted: 22 Sep 2013 12:51 PM PDT

In February, scientists reported the discovery of a previously unknown third radiation ring -- a narrow ring that briefly circled the Earth for a month. Space scientists have successfully modeled and explained the unprecedented behavior of this third ring, and show that its energetic particles are driven by very different physics than the others.
