This is the Andromeda galaxy! It is the furthest thing away from Earth that can still be seen with the naked eye on a clear night. It is 2.3 million light years away from us. The galaxy used to be called the ‘Great Andromeda Nebula’, since they thought that is was a bunch of glowing gases, or a solar system in formation. The Andromeda galaxy is a major galaxy, and is slightly bigger than our Milky Way. So spectacular.
