The Horse-head Nebula (Barnard 33) is an absorption nebula that obscures part of the background H-II area IC 434. The object owes its name to the shape of the nebula and it is probably one of the best known nebulae. To see the famous 'horse's head' the image has to be rotated 90 degrees, therefore it is best to see it when Orion is just in the sky and still lying on his side.
The nebula, which is visually difficult to see because it is near Alnitak, was discovered in 1888 by Williamina Fleming on a photographic plate made with a telescope of the Harvard College Observatory. The nebula IC 434 is ionized by the star σ Orionis against which the dark dust clouds that form the Horse-head Nebula protrude. The entire area, about 1500 light years away, is part of the Orion complex, an area of gas and dust clouds that cover large parts of the constellation Orion and which also includes the Orion Nebula, M78 and Barnard's Loop.
