Institut d'Astrophysique Spatiale

For a mission that has just entered its scientific exploitation phase, Solar Orbiter has already produced many remarkable results. A recent special issue of Astronomy and Astrophysics brings together a multitude of studies and observations obtained during the mission's cruise phase. No less than 56 papers have been published, each containing data produced by one or several Solar Orbiter instruments, in which many laboratories including IAS have been strongly involved.

The first analyzes of the samples collected from the primitive asteroid Ryugu, to which contribute the MicrOmega instrument developed at IAS, provided a first characterization of the physical and chemical properties of the grains.

For the first time, taking advantage of innovative artificial intelligence methods, an IAS team has discovered thousands of galaxy clusters in Planck satellite observations, published in a new catalogue.
