The Andromeda galaxy, which may have been growing by cannibalizing smaller galaxies.

Galactic cannibal Andromeda feasts on smaller galaxies, reveal cosmic remnants

Andromeda, the Milky Way’s neighboring spiral galaxy, may be a cosmic cannibal that grew by swallowing smaller galaxies.

Astronomers came to this conclusion by observing a globular cluster of stars called the Dulais Structure, named after the Welsh term meaning “dark stream”, which now dwells in Andromeda but seems to come from outside galaxy. The Dulais structure is illuminated by star clusters orbiting like no other cluster in Andromeda, meaning the star stream could represent the “leftovers” of a galaxy-sized meal in the past. of Andromeda.
