About this image

The Andromeda Galaxy, also known as Messier 31, M31, or NGC 224 and originally the Andromeda Nebula, is a barred spiral galaxy approximately 2.5 million light-years from Earth and the nearest large galaxy to the Milky Way. In this excellent image by Ian the H-alpha component was combined into the red channel from the RGB and all processing was performed using PixInsight.
