Astronomers propose that the Milky Way's development involved the merging of smaller galaxies, including a potential lost galaxy referred to as 'Loki'.
This hypothesis arises from the understanding that the Milky Way has historically consumed or merged with various smaller galaxies.
Identifying stars within the Milky Way that originated from other galaxies allows researchers to trace the history of galaxy formation.
The discovery of 'Loki' could significantly alter our comprehension of how galaxies evolve and interact over time.
