The most 'pristine' star in the universe discovered by astronomers

Astronomers have discovered SDSS J0715-7334, the most pristine star in the universe, revealing insights into the conditions following the Big Bang.

The star, identified as SDSS J0715-7334, exhibits extremely low metallicity, indicating it formed from primordial hydrogen and helium shortly after the Big Bang.
Led by astronomer Alexander Ji at the University of Chicago, this discovery is part of the ongoing research derived from the Sloan Digital Sky Survey.
SDSS J0715-7334s unique characteristics suggest it formed before the first supernova explosions, which significantly altered the chemical composition of the Milky Way.

Why It Matters

This discovery of SDSS J0715-7334 enhances our understanding of the early universe and the formation of stars, providing a crucial link to the conditions that existed shortly after the Big Bang.
