The Andromeda Galaxy Says 'Cheese!'
The first identifiable photo of the Andromeda Galaxy was taken on December 29, 1888 by amateur astronomer Isaac Roberts. Back then, people still called the galaxy the Andromeda Nebula, thinking it was made of planets. Roberts used a twin telescope to capture the image from his self-made observatory in his home near Liverpool.
