In the outer halo of our galaxy, eighty thousand light-years from Earth, astronomers have found a star so chemically ancient it carries the fingerprints of the universe's earliest moments. SDSS J0715-7334, confirmed by a team from the University of Chicago using Chile's Magellan telescopes, contains less than 0.005 percent of the sun's metal content — making it the most pristine star ever identified and a rare surviving witness to the cosmos just after its first stars lived and died. Its discovery reminds us that the universe keeps its oldest secrets not in distant galaxies, but sometimes in t
