At a bilateral ESA-NASA meeting held on 15-16 July, 2008, David Southwood, the ESA Director for the Science and Robotic Exploration Program, and Ed Weiler, the NASA Associate Administrator of the Science Mission Directorate, endorsed a plan to establish an International X-ray Observatory (IXO) study.

Scientists using the Hubble Space Telescope have found the largest sample of very distant galaxies seen to date: ten promising candidates thought to lie at a distance of 13 billion light-years (a redshift of ~ 7.5).

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.

Hubble's Advanced Camera for Surveys has observed a large portion of the Coma Cluster, stretching across several million light-years. The entire cluster is more than 20 million light-years in diameter, is nearly spherical in shape, and contains thousands of galaxies.

Analysis of XMM-Newton data of G350.1-0.3, a bright galactic radio source, reveals it to be a young and bright supernova remnant (SNR). These results are published in the 10 June issue of ApJ Letters

The proto-typical merger pair the Antennae Galaxies are found to be at a distance of only 0.7 times the previous best estimate of ~65 million light-years, following a recent study based on Hubble data

Using the ESO 2.2m telescope at La Silla, Chile, a team of scientists have sucessfully imaged the position of the WMAP spacecraft at 1.5 million km from Earth, testing the ground-based optical tracking technique to be used for Gaia

A study of nine distant massive galaxies using Hubble and Keck data shows the distant massive galaxies to be much more compact than their counterparts at lower redshifts

Celebrating the 18th launch anniversary of the Hubble Space Telescope on 24 April 2008, a Hubble atlas of interacting galaxies in different stages of interaction and merger is released, comprised of 59 new Hubble images

Based on a study of archival data from four X-ray observatories, including XMM-Newton, a team of Japanese astronomers confirm the black hole at the Galactic centre, Sgr A*, to have experienced an outburst some 300 years ago

XMM-Newton observations of broad absorption line quasars (BALQSOs) that are seen face-on reveal these to be different from BALQSOs that are seen at different orientations in that the former are not deficient in soft X-ray emission

Data from Hubble and the groundbased Gemini observatory provide evidence for the existence of an intermediate-mass black hole in the globular cluster omega Centauri supporting a possible reclassification of the cluster as a dwarf galaxy

Hubble's resolving power has aided in a ten-year search for and study of supernova precursors which was set up to determine which types of stars - in what range of stellar masses - end their lives as a supernova

Two different methods based on optical and X-ray observations have resulted in a consistent identification of the subtype and age of the supernova responsible for the supernova remnant SNR 0509-67.5 in the Large Magellanic Cloud
