Taking advantage of a once in every 15 years opportunity, Hubble has captured unique images of the aurorae on Saturn, simultaneously at both of the planet's poles

A recent study using data from Hubble shows that, contrary to contemporary thought, more than half of the present-day spiral galaxies had peculiar shapes only 6000 million years ago.

A study based on data collected by the four ESA Cluster satellites and the CNSA/ESA Double Star TC-1 spacecraft, provides new insight into the location and duration of ruptures in the Earth's magnetic shield.

Close-up images of asteroid (2867) Steins, obtained with the OSIRIS cameras on Rosetta, have provided extensive new measurements of the physical properties of this main-belt asteroid. Steins is revealed to be a loosely-bound 'rubble pile' whose diamond shape has been honed by the YORP effect. This is the first time this effect has been seen in a main-belt asteroid. The results are reported by H. Uwe Keller and colleagues in the 8 January issue of Science magazine.

The NASA/ESA Hubble Space Telescope has broken the distance limit for galaxies and uncovered a primordial population of compact and ultra-blue galaxies that have never been seen before.

Using the Hubble Space Telescope, astronomers have uncovered two distinct kinds of rejuvenated stars (blue stragglers) in the globular cluster M30. A new study shows that two different processes are responsible for this cosmic face lift.

The MARSIS radar sounder instrument on board Mars Express, designed to study the ionosphere, surface and sub-surface of Mars, can unexpectedly also double as a magnetometer

Preliminary results from the Planck First Light Survey indicate that the data quality is excellent. This bodes well for the full sky survey that has just begun.

The confirmation of the nature of CoRoT-7b as the first rocky planet outside our Solar System marks a significant step forward in the search for Earth-like exoplanets.

XMM-Newton observations of the X-ray pulsator RX J0648.0-4418 have resulted in a solid, model-independent mass estimation of this rare, ultra-massive white dwarf.

To reconcile measured methane enhancements and variations on Mars with the current global chemical-
climate model, both a strong local source and an as yet unidentified and very effective methane destruction mechanism are required, a recent study finds

INTEGRAL's all-sky map of the 511 keV line emission has been used to conclude that dark matter is not the origin of galactic positron annihilation, contrary to what had been assumed in past years.

Using data from the Cluster mission scientists have discovered a mechanism that can account for the heating of the solar wind. This discovery was highlighted in the 12 June 2009 issue of Physical Review Letters.

In-situ measurements of grains in Saturn's E ring show sodium concentrations that point at a subsurface ocean on the icy moon Enceladus, which with its south polar plumes is the main source of the E-ring particles

The Cluster and Double Star missions have reached the milestone of 1000 scientific publications in peer-reviewed journals. After almost nine years in space, the four Cluster spacecraft continue to produce new science and cross new regions of space.

Detailed observations of the first new Soft Gamma Repeater in 10 years strengthen the unified view of the magnetar phenomenon; INTEGRAL and XMM-Newton target of opportunity programmes played a crucial role in this result

The simultaneous detection of broad K and L iron lines in an AGN reveals hitherto unobserved details of the geometry and dynamics of the supermassive black hole at the centre of this galaxy.
