A giant stream of metal-rich stars in the halo of the galaxy M31
TL;DR: In this paper, the authors reported the discovery of a giant stream of metal-rich stars within the halo of the nearest large galaxy, M31 (the Andromeda galaxy), which may have lost a substantial number of stars owing to tidal interactions.
