    Thanks to XMM-Newton, a X-ray astronomy European satellite, scientists from CNRS and CEA discovered a new source of cosmic rays which are different from cosmic rays known until now. In the neighbourhood of the Arches cluster, near the Milky Way center, these particles are accelerated in the shockwave generated by the movement of thousands of young stars at the speed of about 700,000 km/h. These cosmic rays then produce a characteristic X emission while interacting with the atoms of the ambient gas.
