NASA’s Wide-field Infrared Survey Explorer (WISE) provides this image of The Great Nebula in Orion. The Orion Nebula (Messier 42) lies located in the sword of Orion, hanging from his easily recognized belt of three stars. Astronomers now realize that the Orion Nebula makes up part of the larger Orion molecular cloud complex, also including the Flame Nebula. This complex in our Milky Way Galaxy actively makes new stars. Light from these new stars warms the dust filling the nebula, making the dust glow in infrared light. [See More Images]
