Jean-Pierre Bibring, professor emeritus at Institut d'Astrophysique Spatiale (CNRS/Université Paris Sud), has received on July 15th, 2018 the COSPAR Space Science Award for his contributions to the exploration of the Solar System. This award is the most prestigious of COSPAR (Committee on Space Research), and is granted at each biennial general meeting. Among Jean-Pierre Bibring's numerous involvements, COSPAR has highlighted his responsibilities in Mars Express and Philae/Rosetta.

In 2013, the Planck results showed, for the first time, a discrepancy in the cosmological parameters determined from the cosmic microwave background (CMB) and the number counts of galaxy clusters. This inconsistency was also confirmed by the 2015 Planck results and by independent weak lensing and X-ray observation analyses. Researchers at IAS performed a re-analysis, using the 2016 Planck results, and have shown that the CMB and galaxy cluster data now actually converge to the standard model of cosmology, with cold dark matter and a cosmological constant.
