'Most pristine' star ever seen discovered at the Milky Way's edge — and could be a direct descendant of the universe's first stars

Astronomers discovered the most metal-poor star ever observed, named SDSS J0715-7334, located about 85,000 light-years from Earth. This red giant, 30 times more massive than the sun, contains dramatically less iron and carbon than any known star, making it twice as pristine as the previous record holder. The star's extremely low metallicity suggests it's a direct descendant of the universe's first stars, offering scientists a rare window into early stellar evolution and challenging current theories about star formation.
