Researchers Discover the Universe's Oldest Stars Circling the Milky Way

Join us on an extraordinary cosmic journey as we uncover a groundbreaking discovery that takes us back to the dawn of the universe! 🌌✨
In this video, we delve into the fascinating findings of astronomers using the European Space Agency's Gaia spacecraft. They have identified a population of ancient stars, estimated to be over 13 billion years old, located in the outer halo of the Milky Way. These stellar fossils offer a unique glimpse into the early universe, providing crucial insights into the formation and evolution of our galaxy.
Led by Dr. Ana Bonaca from the Center for Astrophysics at Harvard, the research team used precise measurements from Gaia to determine the ages and chemical compositions of these ancient stars. Discover how these stars, some of the first to form in the universe, carry the secrets of the cosmos' earliest moments.
