Star-forming regions interact with their environment in massive galaxies
An international team of astronomers just witnessed how the sites of the most intense star formation in the early Universe communicate with their surroundings through rapid gas exchange. Their findings offer unprecedented insights into the most rapid evolutionary phase of massive galaxies, about 11 billion years ago.

The launch of the BepiColombo spacecraft (ESA/JAXA) took place on October 19, 2018 at 10:45 pm from the Ariane 5 site in Kourou. BepiColombo has successfully started  its long journey to the planet Mercury, with onboard SIMBIO-SYS, a complex of 3 instruments that will map the surface of the planet with unprecedented spatial resolution and spatial coverage. IAS is co-PI of this instrument through the supply of the main electronics and the implementation of the calibration of the integrated instrument.

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.

The Gruber Foundation announcement has just been posted on May 10 at 8 am local time (Yale time) :

The Gruber Foundation is pleased to present the 2018 Cosmology Prize to the Planck Team, and to Jean-Loup Puget and Nazzareno Mandolesi, the leaders of the HFI and LFI instrument consortia, for mapping the temperature and polarization of the cosmic microwave background radiation with the ESA Planck spacecraft.
