M31 (Andromeda Galaxy) as it might be seen outside our galaxy
The animation below shows the original image of M31, fading into a copy of the original image after painstakingly removing the stars of the Milky Way using Photoshop. The resulting image is how the Andromeda Galaxy might appear if viewed from outside our galaxy. The animation is at 25% of the original scale. To see the images individually at 25% and 50% scalse, click on the thumbnails below the animation.
