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.

On 10 December 1999 Ariane 504 blasted off from Kourou in French Guiana carrying onboard ESA's flagship X-ray observatory, XMM-Newton. In the intervening decade this astronomical workhorse has played a significant role in revolutionizing X-astronomy.

Proposals are solicited for observations with XMM-Newton in response to the Ninth Announcement of Opportunity, AO-9, issued 25 August 2009. This AO covers the period May 2010 to April 2011 and is open to all proposers. The deadline for receipt of proposals for this AO has passed.

Detailed observations of the first new Soft Gamma Repeater in 10 years strengthen the unified view of the magnetar phenomenon; INTEGRAL and XMM-Newton target of opportunity programmes played a crucial role in this result

The simultaneous detection of broad K and L iron lines in an AGN reveals hitherto unobserved details of the geometry and dynamics of the supermassive black hole at the centre of this galaxy.

The XMM-Newton mission passes another milestone this month with the publication of its 2000th scientific paper in peer-reviewed scientific journals.

A recent model of the emission from ultra-magnetized neutron stars (magnetars) shows great promise in offering a unified view of the high energy emission from these objects.

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

XMM-Newton has discovered a rare, very massive cluster of galaxies at a redshift z~1. The object, designated 2XMM J083026+524133, is the most X-ray luminous known at its distance and beyond

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

XMM-Newton observations of the unique double pulsar system PSR J0737-3039 have confirmed pulsed X-ray emission from one component and, for the first time, provided strong evidence for X-ray emission from the second pulsar. The XMM-Newton data show that this unusual system displays complex X-ray behaviour.
