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.

Proposals are solicited for observations with XMM-Newton in response to the eleventh Announcement of Opportunity, AO-11, issued 23 August 2011. This AO covers the period May 2012 to April 2013 and is open to proposers from all over the world. The deadline for receipt of proposals for this AO has passed.

A pioneering instrument for the James Webb Space Telescope has completed testing in the UK. MIRI is a key European contribution to the mission, which will be a space telescope with a mirror seven times bigger in area than that of the Hubble Space Telescope.

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.

A wide variety of stars has been studied in the Andromeda Galaxy, our nearest neighbour large spiral galaxy, which is revealed in unprecedented detail in four observations from the Hubble Space Telescope.

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.

Abell 2744, nicknamed Pandora's Cluster, seems to be the result of a simultaneous pile-up of at least four separate galaxy clusters and this complex collision has produced strange effects that have never been seen together before.
