Supernova Remnant is a Giant Particle Collider in Space

  Gamma-ray observations of a supernova remnant interacting with a molecular cloud in the outskirts of our Galaxy highlights the interplay of particle physics and particle astrophysics. Supernova Remnant Simeis 147 In the cosmos we see many examples of particle physics at work on scales that cannot be achieved in manmade, Earth-bound laboratories. One such [continue reading]
