A scientific team led by the University of Alicante, with participation by the Instituto de Astrofísica de Canarias (IAC) has produced a detailed study of the most massive young star cluster in the Milky Way. This cloud of stars contains different types of giant stars in diverse phases of evolution, and can be used as an excellent laboratory for the study of the formation and evolution of massive stars. Stars tend to form in clusters, containing from just a few to several thousand stars, which share the same age and composition, although they show evolutionary differences. Among the clusters

The nearly primordial origin of an ancient star of the Milky Way confirmed by an international team of researchers thanks to the ESPRESSO spectrograph. Stars with very low content of chemical elements are considered to be the older stars in the Milky Way. Formed a few hundred million years after the Big Bang, a very small time compared to the age of the Universe, these stars are real fossils which encode the first phases of the chemical evolution of the Universe in their atmosphere. The star SMSS1605-1443, discovered in 2018, was identified as one of the earliest stars in the galaxy, but its
