IC434 is a dark nebula in the constellation Orion. The nebula is located just to the south of the star Alnitak, which is
farthest east on Orion's Belt, and is part of the much larger Orion Molecular Cloud Complex as seen in this image. The nebula was first recorded in 1888 by Scottish astronomer Williamina Fleming. It is one of the most identifiable
nebulae because of the shape of its swirling cloud of dark dust and gases, which bears some resemblance to a horse's head. NGC2024 (The Flame Nebula) is to the left of the Horsehead.
