12 billion years ago, near the milky Way small galaxies merged and formed a new dwarf galaxy.
The milky way discovered at the moment the smallest galaxy is a cannibal. This is stated in the article Monthly Notices of the Royal Astronomical Society.
Discovered dwarf galaxy about 12 billion years and it is about 100 thousand times “easier” (in solar masses) of the milky way. It is assumed that this size discovered galaxy was reached after “eating” its smaller neighbor.
It is also reported that the two merged galaxies had different metal properties. This is evidenced by the behavior of the blue and red stars: while the first (low metal content) are organized together into a round cluster, red (high metal content) flew away from each other over long distances.
