Andromeda is the nearest major galaxy to our own Milky Way Galaxy. Our Galaxy is thought to look much like Andromeda. Together these two galaxies dominate the Local Group of galaxies. M31 is so distant it takes about two million years for light to reach us from there. Much about M31 remains unknown, including how the center acquired two nuclei.
