Cygnus is a northern constellation lying on the plane of the Milky Way and named after the swan. The constellation contains Deneb, which is one of the brightest stars in the night sky, being the most distant first-magnitude star, and one corner of the Summer Triangle. It also has some notable X-ray sources and the giant stellar association of Cygnus OB2. The swan is typically formed with stars Delta and Epsilon Cygni as its wings, Deneb at the tail, and Albireo as the tip of its beak.Photograph: Ken Crawford
