This image shows the star PicII-503, with the lowest iron content ever measured outside of the Milky Way. With less than 1/40,000th the amount of iron as the Sun, PicII-503 is the clearest example of a star within a primordial system that preserves the chemical enrichment of the Universe’s first stars. PicII-503 also has an extreme overabundance of carbon, providing the missing link to connect carbon-enhanced stars observed in the Milky Way halo to an origin in ancient dwarf galaxies.
