Gamma rays 10 times more energetic than thought possible detected

• arclein
The team calls these powerful cosmic particle accelerators "PeVatrons," although it remains unknown exactly how photons can be accelerated to such intense energies. Their exact sources haven't yet been identified either, but the astronomers say they seem to be linked to star formation, nebulae, and/or supernova remnants. Further observations of these kinds of objects could allow scientists to better understand the origins of cosmic rays.
