On July 4, 2018, at its annual conference held in Bordeaux, the French Society of Astronomy and Astrophysics (SF2A) awarded the Young Lecturer-Researcher 2018 Award to Miho Janvier, assistant astronomer at IAS. Her research focuses on solar flares, from their birth to their propagation in interplanetary space.

At 9h35 JST (Japan Standard Time) this morning, Wednesday 27 June 2018, the Hayabusa2 probe reached its "home position", 20 km from the target asteroid "Ryugu", which is currently at a distance of 1.9 AU (astronomical units, 285 million km) from the Earth.

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.
