    Source of Unprecedented Energy Found at Centre of Milky Way

    A source of cosmic rays radiating energies 100 times greater than those achieved at the largest terrestrial particle accelerator the Large Hadron Collider at the European Organisation for Nuclear Research (CERN) has been found in the innermost region of our Milky Way galaxy. The source was revealed after a detailed analysis of the data collected […]
