The Horsehead Nebula and the Flame Nebula are part of the Orion molecular nebula complex. Located in the constellation Orion, Horsehead is a dark nebula. The darkness of the nebula is mainly caused by dense dust, although the lower part of the »neck« casts a shadow on the left. The flows of gas leaving the nebula are channeled by a strong magnetic field. Light from the Horsehead Nebula takes about 1,500 years to reach Earth. The Flame Nebula is made up of a large H II region visible just east of the bright star Alnitak; its main physical characteristic, which also gives it its name, is a large dark band of dust that crosses it from north to south, progressively widening and giving the bright part of the nebula a flame shape.
