Each civilization had different names for the Milky Way Galaxy, but in the interstellar society, the naming rules of the galaxy were gradually perfected in the interstellar naming method.
Generally speaking, the first person to discover an unrecorded galaxy would have the right to name it. The Star Map Committee in the Milky Way would use this naming as a reference.
There were some historical issues that caused several civilizations to debate over the names of certain important galaxies.
For example, in a special galaxy that was once the home of a fallen civilization, it was a famous tourist destination in the Milky Way.
Although the Milky Way's official name for this place was XXX Bull, there were still some civilizations who remembered the past and insisted that this place was XXXX Boo, and the leader of this extinct civilization would return like lightning one day.
