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.

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.
