Black hole 'particle accelerators' are causing mysterious cosmic rays to rain down on Earth at the speed of light
A study uncovered how cosmic objects are sending accelerated particles through space. Jets coming from quasars and supernovae can send dangerous cosmic rays that hit Earth. For the first time, a study showed how the cosmic rays are accelerated to near the speed of light.
