"Unveiling Galactic Evolution: Ancient Stars Spin Near Milky Way Center"

Astronomers from the Pristine Inner Galaxy Survey (PIGS) have discovered a large group of ancient stars circling the center of the Milky Way in an orderly fashion. These metal-poor stars likely formed less than a billion years after the Big Bang and provide insights into the early Universe. The study of these stars, hampered by interstellar dust, could help unravel the evolution of our galaxy and others like it.
