Orion constellation. The most prominent feature of the constellation is Orion's Belt, a row of three bright stars (centre left). From left to right, these are Alnitak, Alnilam and Mintaka (Zeta, Epsilon and Delta Orionis respectively). At upper left is the red supergiant star Betelgeuse (Alpha Orionis). The blue supergiant star Rigel (Beta Orionis) is at lower right. Directly below the belt, the Orion Nebula is seen as a pink smudge. Orion's belt straddles the celestial equator, so the constellation is seen equally well from both hemispheres. Photographed from Germany.. Stunning Photo Gifts From Science Photo Library
