Astronomers found PicII-503, a 14-billion-year-old star with extremely low iron and high carbon, offering clues about early universe star formation.
Astronomers have discovered PicII-503, an ultra-rare, 14-billion-year-old star in the dwarf galaxy Pictor II, with iron levels less than 1/40,000 of the Sun’s and a carbon-to-iron ratio over 1,500 times higher than the Sun’s.
Classified as a second-generation star, it formed from material enriched by the first stars, suggesting low-energy supernovae that ejected carbon but retained iron.
Found using the Dark Energy Camera and follow-up telescopes, the star’s chemical makeup offers rare insight into the early universe, supporting theories of primordial element formation and galaxy evolution.
