What began as a class project quickly turned into a breakthrough when they spotted an extraordinarily “pristine” star made almost entirely of hydrogen and helium, hinting it formed near the dawn of the universe.Share:\n\nFULL STORY\n\n* * *\n\n!\n\nAn image of our Milky Way galaxy with the position of the Ancient Immigrant star (SDSS J0715-7334) marked with a star symbol.
