A team of Conicet researchers, in collaboration with a Chilean specialist, discovered a “swarm” of stars that is 2,700 light years from Earth and has a short life in astronomical terms, that is, 2 million years. For astronomy, open star clusters are excellent laboratories that allow us to investigate the complex mechanisms involved in the star formation process, the organization indicated in a statement. "These are enormous swarms of hundreds or thousands of stars arising from the same nebula of gas and dust that, because they were born almost simultaneously and in an identical setting, share many of their physical characteristics and are located at almost the same distance. of the Earth," he added. These objects, united by their mutual gravity, coincide in the proportion of the chemical elements that compose them, although they differ in type and size, depending on how much matter each one was able to "snatch" from the mother nebula. Thus, the most massive ones will be hotter and brighter than the less massive ones, even though the latter are the most numerous.
