Summary
New research suggests the Milky Way contains remnants of an ancient dwarf galaxy dubbed Loki. By studying metal-poor stars in the galactic plane, astronomers found distinct chemical signatures shaped by extreme events like hypernovae and neutron star mergers. Despite differing orbits, these stars likely trace back to a single accreted system—evidence that our galaxy grew by absorbing smaller neighbors early in its history.
