... RXJ0822-4300, deduced from 3 Chandra images over 5 years, implies a transverse space velocity of 1,600 km/s for an estimated distance of 7,000 light years. The unusually large space velocity is consistent with the explosion center inferred from proper motions of the oxygen-rich optical filaments, an ...

XMM-Newton



The XMM-Newton, also known as the X-ray Multi-Mirror Mission and the High Throughput X-ray Spectroscopy Mission, is an orbiting X-ray observatory launched by ESA in December 1999 on an Ariane 5 rocket. It is named in honor of Sir Isaac Newton. The telescope was placed in a very eccentric 48 hour elliptical orbit at 40°; at its apogee it is nearly 114,000 kilometres (71,000 mi) from Earth, while the perigee is only 7,000 kilometres (4,300 mi).
