These massive stars could explain Webb’s strangest galaxies
Hubble observations of massive stars in metal-poor dwarf galaxies are revealing clues to why the early universe looks so unusual. Researchers found that stellar winds weaken sharply at extremely low metallicities, potentially allowing massive stars to retain more material and evolve in unexpected ways. The team also found large differences in iron abundance, a key ingredient...
