As darkness falls on viewing night, the constellation of Cygnus, the Swan, is overhead, in the orientation that is shown above, up being north.Because of the pattern of its main stars, it is sometimes known as the Northern Cross (in contrast to the Southern Cross).
One of the most recognizable constellations of the northern summer and autumn, it resembles a swan flying south along the Milky Way. Albireo, a double star with blue and yellow components is at the "head". Deneb, its brightest star, is at the tail and is one star of the summer triangle.
The Summer Triangle is an astronomical asterism involving an imaginary triangle drawn on the northern hemisphere's celestial sphere, with its defining vertices at Altair, Deneb, and Vega. This triangle connects the constellations of Aquila, Cygnus, and Lyra.
Looking toward the south, Jupiter, the fourth brightest object in the sky, is in the constellation of Sagittarius. Venus is setting in the west.
