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 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]
