Arachnophobes beware: Hubble snaps close-up of the Tarantula [heic1105]
Hubble has produced an outstanding image of the central region of the famous Tarantula Nebula, a vast star-forming cloud of gas and dust in our neighbouring galaxy, the Large Magellanic Cloud.

ESA remembers the night of the comet
Twenty-five years ago, ESA made its mark in deep space. A small spacecraft swept to within 600 km of Halley's comet. The Giotto probe was nearly destroyed by the encounter but what it saw changed our picture of comets forever.

First results of Cluster's auroral acceleration campaign
[01/02/2011]
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.

The Crab Nebula: standard candle no more?
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...

Planck's successful hunt probes galaxy clusters on very broad mass range
The first all-sky survey of galaxy clusters detected via the Sunyaev-Zel'dovich effect is amongst the highlights presented by the Planck Collaboration at a conference held from 10 to 14 January 2011 in Paris, France. The survey, which has benefited from a fruitful collaboration with ESA's XMM-Newton observatory, probes a wide range of cluster masses and other properties, which is unprecedented for a Sunyaev-Zel'dovich sample. Along with the first results enabled by the survey, the Early Sunyaev-Zel'dovich Cluster sample is being publicly released, providing the community with a robust data set for further studies and follow-up observations of galaxy clusters.

Planck sees traces of early structure formation in the cosmic infrared background
While targeting the Cosmic Microwave Background, Planck has also captured another important diffuse radiation, the Cosmic Infrared Background, which consists of the light emitted by all galaxies since their formation. This signal, detected by Planck at submillimetre wavelengths, exhibits a high degree of structure and enables astronomers to investigate the still unclear link between star-forming galaxies and the underlying distribution of dark matter, up to the earliest phases of the formation of cosmic structure. This result is amongst the highlights presented by the Planck Collaboration at a conference held from 10 to 14 January 2011 in Paris, France.

Planck traces the coldest objects in the nearby Universe
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.
