Scientists Say There’s Something Huge Buried Inside Our Galaxy

Astronomers report evidence that a hidden ancient dwarf galaxy, nicknamed Loki, may be buried inside the Milky Way.

The study of 20 metal-poor disk stars found chemical signatures consistent with a short-lived galaxy that merged long ago.

Mixed stellar orbits add support for an early accretion scenario in the Milky Way’s history.

If confirmed, Loki could provide a rare fossil record of the galaxy’s early growth and dwarf-galaxy mergers.
