This artist rendering provided by NASA shows the Van Allen radiation belts around Earth. A new study published Thursday Feb. 28, 2013, in the journal Science reports that NASA’s recently launched twin satellites to the region discovered a third, temporary ring. It appeared for a month before a shock wave from the sun destroyed it. Scientists are still trying to figure out how often this happens. (AP Photo/NASA)
