Beginning the 1st December at an international conference in Ferrara (Italy), the Planck collaboration, which involves the CNRS, the CEA, the CNES and several French universities among other institutes, reveals the results of four years of observation by the ESA Planck satellite of the Cosmic Microwave Background (CMB), the oldest light in the universe. For the first time, the CMB is accurately measured on the whole sky in both its intensity and polarisation.

After a fascinating sequence, with a descent phase perfectly as planned and an impact at a few tens of metres from the selected site followed by two rebounds, Philae finally stopped in a hollow surrounded by cliffs, in an acrobatic position. It is the first panorama taken by the CIVA cameras developed under IAS responsibility which has demonstrated this, confirming the first major success of the mission: Philae has landed and has operated on the nucleus of comet Churyumov-Gerasimenko!

The Planck consortium has published a statistical analysis of the dust polarization towards the regions of the sky best suited to measure Cosmic Microwave Background polarization. This work shows that dust polarization is significant over all of the sky, and that the signature of cosmic inflation will not be detected unless contamination associated with the dusty and magnetized interstellar medium in the Galaxy is removed with the required accuracy and confidence.
