"Pigs Uncover Ancient Stars at the Core of the Milky Way"

The Pristine Inner Galaxy Survey (PIGS) team has discovered a group of ancient stars in the center of the Milky Way that are slowly spinning around the galactic center. These stars, which formed less than a billion years after the Big Bang, have a pristine chemical composition and spend most of their lives near the Galactic center. The PIGS project used special imaging filters and spectroscopic observations to obtain the largest set of detailed observations for these ancient stars. The findings provide valuable insights into galaxy formation and the early Universe.
