Astronomers have identified chemical and kinematic evidence for a previously unknown dwarf galaxy, dubbed "Loki," that merged with the Milky Way during its earliest epoch of formation. Based on analysis of 20 metal-poor stars in the galactic plane with unusual orbital and chemical properties, the finding adds a new chapter to the Milky Way's complex merger history — though questions remain about the robustness of the evidence and the completeness of our census of galactic building blocks.
