The Orion Nebula (what this is a photo of) is actually in the Milly Way, like all other Astro photos you may see (minus galaxies). This then means the Doppler effect doesn’t take place, causing the natural colour of the stars to show, which in this case is blue. If you zoom in you can find stars which are red and white
