Andromeda | What Does the Galaxy Closest to Us Conceal?

It is currently known that the Andromeda Galaxy has a spiral structure and comprises about a trillion stars. As for its diametre, it exceeds 150 thousand light-years, and its mass is relatively small and ranges from 800 billion to one and a half trillion solar masses - about the same as the Milky Way. This is thought to be the case due to the abundance of red dwarfs and less dark matter in its composition.
