  Mechanism explains how the most energetic form of light can be produced in areas dominated by bright, young stars
   
   n 2002, when astronomers first detected cosmic gamma rays – the most energetic form of light known – coming from the constellation Cygnus they were surprised and perplexed. The region lacked the extreme electromagnetic fields that they thought were required to produce such energetic rays. But now a team of theoretical physicists propose a mechanism that can explain this mystery and may also help account for another type of cosmic ray, the high-energy nuclei that rain down on Earth in the billions.
