    A black hole of more than 500 times the Sun's mass was discovered. It is an intermediate one between the stellar and super-massive black holes. This "missing link" just got discovered by an international team led by investigators of the Centre for the Study of Radiation in Space of Toulouse. This world-first discovery was achieved thanks to observations of ESA's XMM-NEWTON satellite. This result was announced in the July 2nd, 2009 issue of Nature.

    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.
