APOD 2.7



This incredible photograph is of the group of reflection nebulae in Orion called NGC 1977, NGC 1975, and NGC 1973. This cluster of nebulae is usually overshadowed by its glittering nearby neighbor, the Orion Nebula. The clouds reflect the light off of hot blue stars which is how they gained their brilliant colors. NGC 1977 is the cloud going across the picture slightly below the center, while NGC 1973 occupies the top right and NGC 1975 is in the top left and all of these clouds are separated by the dark red clouds of hydrogen gas.
