The European Space Agency’s Gaia mission has made an unexpected discovery in the Milky Way that will revolutionize our understanding of how stars form and evolve. After surveying over a million stars in the Milky Way, Gaia’s observations have revealed that a large fraction of star clusters contain multiple core regions, a phenomenon previously unseen. This is an exciting breakthrough, as it suggests that star formation may be more complex than previously thought. With this new information, astronomers will be able to learn more about star formation and gain a better understanding of the Milky Way’s stellar population.
