B33 - "Horsehead Nebula" in Orion

Barnard 33 (IC 434) is a dark nebula that, for obvious reasons, is commonly known as the Horsehead Nebula. It is approximately 1500 light years away and is part of the much larger Orion Molecular Cloud Complex. It lies just south of the bright star Alnitak, the eastern-most star in Orion's belt. It was first recorded on a photographic plate by Willaminia Fleming in 1888.
