Data from the VIRGO instrument on SOHO have been used to show that solar flares drive global oscillations in the Sun. This confirms a prediction made more than 30 years ago.

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

Based on Cassini radar observations of Titan's surface the moon's spin rate is now confirmed to be both non-synchronous and changing, providing evidence for the existence of a subsurface ocean

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

In a recent article in Astrophysical Journal Letters Sala et al. shed light on the nature of the postoutburst nova V5116 Sagittarii with new XMM-Newton observations of the white dwarf star's soft X-ray emission

In-situ observations by the multiple Cluster spacecraft, together with numerical simulations, form the first ever confirmation of the occurence of solitary waves in Earth's magnetopause and explain the spontaneous generation of these waves

Eta Carinae is a complex binary system, at a distance of around 8000 light years, with a large nebulosity surrounding the central objects. Observations with INTEGRAL have confirmed the nature of hard X-ray emission from the region to be from inverse compton scattered photons accelerated in a region where two stellar winds collide.

Astronomers using the NASA/ESA Hubble Space Telescope have compiled a large catalogue of gravitational lenses in the distant Universe. The catalogue contains a staggering 67 new gravitationally lensed images found around massive elliptical and lenticular-shaped galaxies.

First ever observations by Cluster of the actual size of the electron diffusion region at the heart of magnetic reconnection reveals the region to be much larger than previously thought, with implications for design and operations of future space missions

Cluster observations of the Earth's space environment being affected by a Coronal Mass Ejection from the Sun have established the existence of a mechanism for accelerating plasma in the Earth's magnetosheath other then magnetic reconnection

Cluster results published by Tony Lui et al. give new insight into the generalized Ohm's law that discribes the coupling between charged particles and a magnetic field, as applied to magnetic substorms in Earth's magnetosphere

A detailed study of six years' worth of data gathered by the EDI instruments on board the Cluster spacecraft has provided polar maps of plasma dynamics in Earth's ionosphere and its relation to solar activity
