Astronomers may have identified the most pristine star to date, likely formed from gas originating from the universe's first stars, Population III, which are theorized to be massive, hot, and metal-free. The star, SDSS J0715-7334, is the most metal-poor star observed in our galaxy, providing insights into the early universe, although it is not a direct detection of Population III stars. The search for these primordial stars continues with advanced telescopes like James Webb.
