M78 and Orion Dust Reflections
In the vast Orion Molecular Cloud complex, several bright blue nebulas are particularly apparent. Pictured here are two of the most prominent reflection nebulas - dust clouds lit by the reflecting light of bright embedded stars . The more famous nebula is M78 , in the image center, cataloged over 200 years ago. To its left is the lesser known NGC 2071 . Astronomers continue to study these reflection nebulas to better understand how interior stars form. The Orion complex lies about 1500 light-years distant, contains the Orion and Horsehead nebulas, and covers much of the constellation of Orion . Almost Hyperspace: Random APOD Generator
