The Orion constellation and its nebulae. The two Orion's bright stars are both supergiant stars: Betelgeuse (a red one) and Rigel (blue one). The center of this constellation is the Orion Belt with the Horsehead nebula (IC 434-B33). Lower, the great Orion nebula, M42, a large star forming region. Also visible on this image, the Barnard's loop, a very faint nebula.
