"Discovery of Ancient Star Formed in Another Galaxy"

Scientists have discovered one of the most ancient stars, which formed in a different galaxy from ours, providing insight into the early element-forming process in galaxies. This star, found in the Large Magellanic Cloud, is from the second generation and has much less heavy elements than any other star seen in the cloud, suggesting differences in early element enrichment processes across different regions. The discovery opens up the field of stellar archaeology in the Large Magellanic Cloud and sheds light on how the first stars chemically enriched the universe in various environments.
