Using the Cerro Tololo Inter-American Observatory (CTIO), astronomers have detected more than 300 pulsating variable stars by observing the Milky Way’s satellite galaxy Antlia 2 (or Ant 2 for short). The finding, reported in a paper published December 15 on arXiv.org, could improve our understanding of this galaxy and its surroundings.
