The release of a new catalogue from the XMM-Newton space telescope provides an unprecedented cosmic X-ray library for the exploration of the extreme Universe. The third XMM-Newton Serendipitous Source Catalogue (3XMM-DR4) contains more than half a million sources.

Scientists have discovered a long-sought piece in the puzzle of where high-energy particles in Earth's magnetosphere come from. Using data from ESA's Cluster mission, they found that magnetic reconnection can accelerate electrons to very high energies, as long as reconnection happens at a variable pace rather than steadily.

Astronomers using the NASA/ESA Hubble Space Telescope have, for the first time, determined the true colour of a planet orbiting another star. If seen up close this planet, known as HD 189733b, would be a deep cobalt blue, reminiscent of Earth's colour as seen from space.

The Royal Observatory of Belgium invites proposals from potential Guest Investigators for the analysis of data from PROBA2's two solar observation instruments, SWAP and LYRA. Proposals in response to this Fourth Call for Ideas must be received by 16 August 2013.

The construction of ESA's Euclid space mission to explore the 'dark Universe' will be led by Italy's Thales Alenia Space as prime contractor, beginning the full industrial phase of the project.

A steady wind, discovered by ESA's Cluster mission, is slowly escaping from Earth's plasmasphere - the torus of plasma that surrounds our planet's atmosphere. The outflow amounts to almost 90 tonnes a day. Predicted by theory two decades ago, this is one of the main mechanisms that replenishes Earth's magnetosphere with fresh plasma.

ESA's billion-star surveyor, Gaia, has completed final preparations in Europe and is ready to depart for its launch site in French Guiana, set to embark on a five-year mission to map the stars with unprecedented precision.

The Hubble Space Telescope has produced this vivid image of a pair of interacting galaxies known as Arp 142. When two galaxies stray too close to each other they begin to interact, causing spectacular changes in both objects.

ESA has extended the productive lives of 10 of its operating space science missions. This decision secures funding for ESA's world-class science missions until at least the end of 2014, and provides a framework for planning until end of 2016.

As the closest planet to Earth, Venus is a relatively easy object to observe. However, many mysteries remain, not least the super-rotation of Venus' atmosphere, which enables high altitude winds to circle the planet in only four days. Now images of cloud features sent back by ESA's Venus Express orbiter have revealed that these remarkably rapid...

A survey from Herschel has revealed that the reservoir of molecular gas in the Milky Way is hugely underestimated - almost by one third - when it is traced with traditional methods. The discovery not only indicates that there is more raw material for the formation of new stars in the Galaxy, but also that it extends farther than astronomers knew.

The module carrying the telescope and scientific instruments of ESA's Euclid 'dark Universe' mission is now being developed by Astrium in Toulouse, France.

Scientists have confirmed the presence of PAHs - Polycyclic Aromatic Hydrocarbons - in the upper atmosphere of Saturn's largest moon, Titan. After forming, PAHs grow into larger aggregates that drift down, eventually giving rise to aerosol particles in the haze layer that blankets Titan's surface. The study is based on data from the Cassini...

New global maps of Mars released on the 10th anniversary of the launch of ESA's Mars Express trace the history of water and volcanic activity on the Red Planet, and identify sites of special interest for the next generation of Mars explorers.

The NASA/ESA Hubble Space Telescope has produced the most detailed observations ever of the Ring Nebula (Messier 57). This image reveals intricate structure only hinted at in previous observations, and has allowed scientists to construct a model of the nebula in 3D - showing the true shape of this striking object.

Astronomers have found a rare encounter between two massive and gas-rich galaxies in a survey from Herschel. The event took place when the Universe was only about three billion years old and involved two galaxies forming stars with exceptional efficiency whilst in the process of merging. This galactic collision would go on to form a very massive...

The NASA/ESA Hubble Space Telescope has found signs of Earth-like planets in an unlikely place: the atmospheres of a pair of burnt-out stars in a nearby star cluster. The white dwarf stars are being polluted by debris from asteroid-like objects falling onto them. This discovery suggests that rocky planet assembly is common in clusters, say...

Observing the Galactic Centre with Herschel, astronomers have detected molecular gas at surprisingly high temperatures - up to 1000 K. The molecules are probably heated up by shocks as gas surges towards Sagittarius A*, the region harbouring the supermassive black hole at the centre of the Milky Way.

For the first time, scientists have resolved the detailed structure of the core region where magnetic reconnection takes place in the magnetosphere of Earth using unprecedented wave measurements. The study, based on data from ESA's Cluster mission, has mapped different types of electrostatic waves in this region. The waves trace populations of...
