Planck sees new, mysterious components in Milky Way and Magellanic Clouds
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.

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.

Planck's first glimpse at galaxy clusters and a new supercluster
Planck has obtained its very first images of galaxy clusters, amongst the largest objects in the Universe, by means of the Sunyaev-Zel'dovich effect, a characteristic signature they imprint on the Cosmic Microwave Background

Star formation processes highlighted by Planck
The processes involved in star formation can be disentangled using the power of multi-frequency observations. New images from Planck reveal the interstellar medium and isolate the physical processes at work in our Galaxy.

How constant is our changeable Universe?
Constants govern the way our Universe behaves. We regard them as fixed, unchanging quantities. However, how can we be sure that constant really means constant? Modern theories require the values of universal constants to slowly change during the course of cosmic history. Is this the case? ESA is preparing to search for (small) changes in the 'constants of nature'.

MAP blazes the way for Planck, ESA's probe into the birth of the Universe
In trying to explain the origins of the Universe scientists have taken a step-by-step approach, and ESA's Planck is currently at the top of the staircase. Several experiments, both on Earth and in space, are blazing the trail which will soon be travelled by Planck, on its search for the holy grail of cosmology: the set of 'magic numbers' which define our Universe. Planck, the 'ultimate' tool to find out how everything started, is the first European space mission to study the Big Bang and will be launched in 2007.

Danish Space Research Institute to build the mirrors of ESA's Planck telescope
The Danish Space Research Institute (DSRI) will develop the main elements of the telescope of ESA's Planck satellite, according to a document signed yesterday by ESA and the DSRI at ESA headquarters in Paris. Planck, due to be launched in 2007, will study the origin and evolution of the Universe by observing the Cosmic Microwave Background radiation, the first light that filled the Universe after the Big Bang.
