Herschel has found the first evidence of Earth-like water in a comet; this promises to reopen the debate on the role of comets in delivering water to our planet.

New analysis of data sent back by the SPICAM spectrometer on board ESA's Mars Express spacecraft has revealed for the first time that the planet's atmosphere is supersaturated with water vapour.

New insights into the processes by which stars age have been revealed by ESA's Herschel Space Observatory, which is providing unprecedented images of the complex, outer structure of a nearby circumstellar envelope.

Herschel's deep galaxy survey reveals that, contrary to previous belief, most stars in cosmic history did not form through violent mergers but via steady and gentle processes.

Bright auroral displays are caused by a phenomenon known as a geomagnetic substorm, but the origin of these substorms has been debated for decades. New computer simulations, allied to analysis of data from ESA's Cluster spacecraft, are now filling in many of the missing pieces in the puzzle.

Scrutinising Active Galactic Nuclei with INTEGRAL, astronomers have found an unexpected excess of hard X-ray emission which reopens the debate on the nature of these powerful sources.

Herschel has found the first robust evidence of molecular oxygen in the Orion Nebula, shedding new light on where most interstellar oxygen might be 'hidden'.

Herschel has detected water in a huge torus around Saturn, which is supplied by its moon Enceladus and, in part, precipitates into the atmosphere of Saturn.

Astronomers have detected a surprisingly large amount of dust in the remnant of supernova SN1987A, located in the nearby Large Magellanic Cloud, shedding new light on the mechanisms that produce dust in galaxies.

New insights into the processes that modify high speed plasma flows, or jets, have been provided by rare in situ measurements of these streams of ionised particles, made by the four Cluster spacecraft.

ESA's INTEGRAL gamma-ray observatory has provided results that will dramatically affect the search for physics beyond Einstein. It has shown that any underlying quantum 'graininess' of space must be at much smaller scales than previously predicted.

Astronomers using XMM-Newton have captured a neutron star undergoing a rare, intense flare, which may have been produced when the star ingested a massive clump of matter.

New results from Cassini-Huygens provide the strongest evidence yet for the existence of large-scale saltwater reservoirs beneath Enceladus' icy crust.

CoRoT's detection of ten new exoplanets, including a system of two Neptune-like objects, reveal a diverse population of planets orbiting stars beyond our Sun.

Herschel's detection of molecular gas outflows in merging galaxies proves that feedback processes can exhaust the galactic gas supply for creating stars and feeding the black hole.

An intricate network of filamentary structure, exposed in extraordinary detail by Herschel, has provided new evidence for how stars form from the diffuse interstellar medium.

Using the amplifying power of a cosmic gravitational lens, Abell 383, astronomers have discovered a distant galaxy whose stars were born unexpectedly early in cosmic history.

New analysis of images taken by ESA's Venus Express orbiter has revealed surprising details about the remarkable, shape-shifting collar of clouds that swirls around the planet's South Pole.

Can the powerful jets originating from the vicinity of black holes emit gamma rays? INTEGRAL observations of the X-ray binary system Cygnus X-1 have shown that they can.
