What can auroras on a rogue planet teach astronomers about planetary formation and evolution? This is what a recent study published in Astronomy & Astrophysics hopes to address as an international team of researchers investigated the atmospheric composition of a nearby rogue planet, including its atmospheric temperature and auroras. This study has the potential to help astronomers better understand rogue planets, along with additional planetary atmospheric formation and evolutionary traits.
