M31- Andromeda Galaxy

M31 Andromeda Galaxy

Our nearest major galaxy neighbor at 2.5 million light years with similar size but almost twice as many stars. Amazingly it was not known that this was a galaxy outside our own until astronomer Edwin Hubble made the discovery in 1923. Observations of variable stars within Andromeda enabled the distance to be calculated and at that point in history the universe suddenly became a lot bigger. Before that it was thought our Milky Way galaxy was all there was in the universe!

The Andromeda galaxy is located in the constellation of the same name and in a reasonably dark sky it can be spotted with the naked eye in late Summer and Fall.
