A mysterious high-altitude layer of sulphur dioxide discovered by ESA's Venus Express has been explained. As well as telling us more about Venus, it could be sending a warning to those on Earth seeking to inject our atmosphere with sulphur droplets in an attempt to mitigate climate change.

The Cassini-Huygens mission has detected a very tenuous atmosphere known as an exosphere, infused with oxygen and carbon dioxide around Saturn's icy moon Rhea.

Astronomers have exploited the radioactive decay of an isotope of aluminium to estimate the age of stars in the nearby Scorpius-Centaurus association, the closest group of young and massive stars to the Sun.

Another milestone in the development of ESA's Gaia spacecraft has been passed with the successful conclusion of two parallel test programmes during October, which demonstrated that the focal plane assembly is structurally and functionally fit for flight.

ESA has decided to extend the productive lives of 11 of its operating space science missions. This will enable ESA's world-class science missions to continue returning pioneering results until at least 2014.

Observing the X-ray-bright gas in the halo of the Milky Way, ESA's XMM-Newton has gathered new data which favour a process involving fountains of hot gas in our Galaxy.

Astronomers using early data from one of the largest projects to be undertaken with Herschel have demonstrated that virtually all bright sub-millimetre galaxies in the distant Universe are subject to gravitational lensing.

A European Roadmap for Exoplanets, a report from the ESA-appointed Exoplanet Roadmap Advisory Team (EPR-AT), is now available. The roadmap looks at the future of the field and how to reach the ultimate, long-term goal: finding an Earth-like planet with possible signatures of life.

Using Hubble to obtain the most accurate measurements yet of star motions at the heart of Omega Centauri, a globular cluster in the Milky Way, astronomers have now calculated how these stars will move over the next 10 000 years

An extensive series of ground tests on LISA Pathfinder's optical payload successfully achieved - for the first time on a spacecraft instrument - the incredible precision required to confirm the existence of gravitational waves.

Astronomers using XMM-Newton and other world-class X-ray telescopes have probed a curious source, which emits flares and bursts just like a magnetar but lacks the extremely high external magnetic field typical of these objects.

A team of astronomers have used Hubble to study the aftermath of a collision between two asteroids over a period of several months

High-resolution images from the Hubble Space Telescope and a rare view obtained, from a unique perspective, by the Rosetta spacecraft provide a comprehensive picture of P/2010 A2, a puzzling body in the asteroid main belt.

Data from the SOHO and GOES spacecraft have enabled a team of European scientists to shed new light on the role of solar flares in the total output of radiation from the Sun. Their surprising conclusion: X-rays account for only about 1% of the total energy emitted by these explosive events.

New density measurements, centred on the Northern Pole and obtained during the Venus Express Atmospheric Drag Experiment, show an unexpected inhomogeneous pattern in the atmosphere of our neighbouring planet.

The International Academy of Astronautics (IAA) has decided to award The Laurels for Team Achievement Award to the Double Star/Cluster Team. The official ceremony took place in Prague, Czech Republic, on 26 September, in the margin of the International Astronautical Congress.

During a test performed on Rosetta's Reaction Control System (RCS) on 9 September 2010, a leak has been identified in this sub-system in an area which cannot be isolated. Despite the unwelcome news, an operation strategy has already been defined that conserves the mission objectives without re-pressurisation of the RCS system. Rosetta will...
