Astronomers have spotted PicII-503, an ancient Population II star inside the 10+ billion-year-old dwarf galaxy Pictor II. This star is unusually rich in carbon relative to iron, a clue that carbon—crucial for life—was synthesized in early supernovae and distributed throughout the universe, helping explain why carbon is so widespread.
Scientists using the Dark Energy Camera identified PicII-503, an iron-poor second-generation star in the ultra-faint dwarf galaxy Pictor II, with iron about 1/40,000 that of the Sun and a carbon overabundance, providing a fossil record of how the first stars enriched later generations and shedding light on primordial element production in the early universe.
Astronomers identified PicII-503, an extremely metal-poor second-generation star in the dwarf galaxy Pictor II, with just 1/40,000th the Sun's iron and a striking carbon overabundance. This rare star acts as a fossil record of the universe's earliest element production, offering clues about how the first stars enriched later generations and linking to signatures seen in Milky Way halo stars; the discovery was reported in Nature Astronomy.
