Orion Constellation

Orion, one of the most recognized constellations, is visible high in the night sky during winter. It includes several prominent, bright stars including the red giant Betelgeuse (Alpha Orionis) at upper left and blue giant Rigel (Beta Orionis) at lower right. In the center is Orion's "belt" consisting of three bright blue stars. The Orion Nebula is in his "sword" below the belt, just visible to unaided eyes in very clear, dark skies.
