On October the 7th, one of the CIVA cameras took a new striking image of Rosetta with comet Churyumov-Gerasimenko in the background, at only 16 km. The CIVA instrument on the Philae lander (now still attached to the Rosetta orbiter) is a suite of cameras which were developed under IAS responsibility.

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.
