A multidisciplinary team of researchers from IAS, CSNSM, IPAG, ISMO, LMCM-MNHN, and the SMIS/SOLEIL beam line has characterized in the laboratory micrometeorites collected in Antarctica which are particularly rich in organic matter. The chemical composition measured in this study reveals that these particles, some tens of microns in size, could result from regions located beyond the orbit of Neptune.

The Planck collaboration releases today the first cosmological results from the first 15 months of Planck observations. The data tell us about the history and composition of the Universe. They also give us evidence, for the first time, of an effect predicted by inflation models.

ESA has selected the experiments that will be developed for its JUpiter ICy moons Explorer (JUICE) mission, that will study Jupiter, its satellites and its rings. IAS is involved in two of the selected instruments, including a major involvement in the MAJIS visible and near-infrared imaging spectrometer.

The « Curiosity » rover (MSL mission, NASA) has succeeded in drilling at a depth of a few centimetres within a martian rock, which constitutes a major first for the mission. These samples will be analyzed by the instruments on-board the rover, with main the goal of finding clues for the habitability of Mars, in particular for the presence of liquid water at the surface in a distant past.
