Orion is one of the most prominent and beautiful of all constellations. Features include the bright orange star Betelgeuse (upper left), the blue-white star Rigel (lower right), Orion's Belt (three stars at center), and the Orion Nebula (fuzzy zone below the belt). Betelgeuse and Rigel are often featured in science fiction, but neither star would be a good home for life. And if life has evolved at either star, it's doomed: both are destined to explode as supernovae. [Mouser/Wikipedia]
