The Andromeda Galaxy is 2.5 million light-years away from Earth, which means that the light seen from it has traveled 2.5 million years to reach Earth. Maybe such a distance seems very long and even if we travel at the speed of light, 2.5 billion years are needed to travel to the Andromeda galaxy, but on a cosmic scale, especially the distance between galaxies is a small number. In this way, we can actually observe the past of the Andromeda Galaxy from the Earth, and maybe this galaxy has changed a little now. Scientists think that the Andromeda Galaxy can be between 5 and 10 billion years old. One of the interesting features of this galaxy is the presence of a double nucleus, which is probably the result of a merger of a small galaxy with it in the past. Also, according to a 2018 study, Andromeda may not have been like this until two or three billion years ago, when two smaller galaxies that orbited each other collided to give Andromeda its current shape. 2 replies
