Three articles published in the journal “Astronomy & Astrophysics” report different aspects of a large study of 86 protoplanetary disks located in three different regions of the Milky Way. Teams of researchers with several shared members used the SPHERE instrument mounted on ESO’s Very Large Telescope (VLT) in Chile as part of the GTO and DESTINYS observation programs. The findings offer a treasure trove of information about planetary formation in the cosmic neighborhood that could lead to advances in current models and aid follow-up studies.
