Ultra‑metal‑poor star as cosmic fossil

Astronomers say they have found an extremely metal‑poor (chemically pristine) star whose atmosphere preserves the element mix produced by the earliest supernovae. Such a star acts as a fossil record of the first generation of stars and lets scientists test models of Population III nucleosynthesis and early galaxy enrichment. — A concrete, data‑backed window into the first stars changes how we talk about cosmic origins and informs priorities for telescopes, surveys and science literacy.
