The latest edition of the 2XMM catalogue boasts an additional
42 000 entries, bringing the total to over a quarter of a million X-ray sources. This unprecedented cosmic X-ray library is a valuable resource allowing astronomers to explore the extreme Universe.

XMM-Newton, ESA's X-ray observatory, has reestablished communication contact with Earth, showing that the spacecraft is safe and fully under control. The news was confirmed this morning by the mission control team at ESA's European Space Operations Centre (ESOC) in Darmstadt, Germany.

During last weekend ESA lost contact with its XMM-Newton X-ray observatory. Many space agencies and organisations are now joining forces trying to fix the problem: a feeble radio signal has been heard, and ground-based observations confirm that the spacecraft is intact.

The first detection of strong, quasi-periodic oscillations (QPO) in the X-ray emission of an active galaxy (RE J1034+396), obtained with XMM-Newton, is reported in the 18 September issue of Nature

A nova explosion is usually detected first at optical wavelengths. The recent nova V598 Puppis, although being among the brightest novae, was instead discovered first in X-rays by XMM-Newton, some four months after the optical emission had peaked
