sorae – The Milky Way galaxy absorbed another galaxy “Gaia Enceladus” 10 billion years ago

Research results were announced in November 2018 that revealed the history of a small galaxy colliding with the Milky Way galaxy 10 billion years ago. The galaxy was said to be about the same size as the Large and Small Magellanic Clouds, and about one-tenth the size of the present-day Milky Way. The small galaxy that collided with and was absorbed by the Milky Way has been named Gaia-Enceladus by the research team.
Please refer to the original article for details.
The Milky Way galaxy is thought to have repeatedly collided and merged with other galaxies such as Sequoia and Kraken even after the collision with Gaia and Enceladus. In the past, sorae has also introduced the “Family Tree of the Milky Way Galaxy Deciphered by AI,” so please check it out as well.
