Stellar archaeology is the study of the early history of the universe, based on its early composition.^[1] By examining the chemical abundances of the earliest stars in the universe: metal-poor, Population II stars; insights are gained into their earlier, metal-free, Population III progenitors. This sheds light on such processes as galaxy formation and evolution, early star formation, nucleosynthesis in stars and supernovae, and the formation processes of the galactic halo.^[2]^[3] The field has already discovered that the Milky Way cannibalizes surrounding dwarf galaxies, giving it a youthful appearance.^[4]
