Eight articles published in the journal “Astronomy & Astrophysics” report as many studies connected to the ALPINE (ALMA Large Program to Investigate C+ at Early Times) project, conducted using the ALMA radio telescope in 70 hours of far infrared observations of 118 galaxies in the early universe. The researchers who conducted the various studies discovered among other things galaxies that are more mature than primordial, in the sense that they contain a significant amount of dust and metals, a situation found in galaxies where many stars were already produced and exploded into supernovae. This is a confirmation that the first cases of galaxies that were already mature when the universe was still young were not isolated.
