How much dark matter is needed to trigger a starburst in the cosmic cribs where galaxies are born? A new study, based on data from ESA's Herschel Space Observatory, yields an answer.

Cluster is providing new insights into the processes that generate Earth's auroras (and those of other planets). Flying in formation above the planet's poles, the spacecraft are gathering the first multi-point observations of auroral nurseries.

Pushing the Hubble Space Telescope to the limit of its technical ability, an international collaboration of astronomers have found what is likely to be the most distant and ancient galaxy ever seen.

Teaming up with other telescopes monitoring the Crab Nebula, ESA's INTEGRAL observatory has made a significant contribution to demonstrating that this source, previously believed to be a standard candle, might not be so reliable, after all. The small, but measurable dimming of what was until now considered to be one of the brightest and, most...

Thanks to its broad spectral coverage and very high sensitivity, Planck is peering deep into the interstellar medium of the Milky Way and discovering new components and physical mechanisms taking place therein.

The Planck Collaboration presents the first science results to emerge from the mission, covering compact and diffuse foreground emission sources, at a conference this week.

With its power to detect cosmic material at unprecedentedly low temperatures, Planck has completed the first unbiased, all-sky survey of compact cold and dusty objects in the Milky Way and, at the same time, the first all-sky survey of cool dust in other galaxies.

A strange, glowing green cloud of gas that has mystified astronomers since its discovery in 2007 has been studied by Hubble. The cloud of gas is lit up by the bright light of a nearby quasar, and shows signs of ongoing star formation.

Two ESA observatories have combined forces to show the Andromeda Galaxy (M31) in a new light. Herschel sees rings of star formation in the most detailed image of M31 ever taken at far-infrared wavelengths, and XMM-Newton shows X-rays from dying stars.

A recent study concludes that galactic mergers do not usually whet the appetite of the black holes that power these active galactic nuclei.

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.

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.

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

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.
