Constellation Cygnus
The constellation Cygnus, commonly known as the Northern Cross, is a prominent feature of the night sky in the Northern Hemisphere. Its name is derived from the Latin word for swan, as its shape resembles a graceful flying bird.
Appearance and Location
Cygnus is located in the third quadrant of the northern hemisphere, visible between latitudes +90° and -40°. It can be observed during the summer months in the northern hemisphere and appears high in the sky.
One of the most recognizable features of Cygnus is its distinctive cross shape formed by the brightest stars of the constellation. The stars Deneb, Sadr, and Gienah mark the top, center, and bottom of the cross, respectively. Albireo, a famous binary star system, is also found in the constellation.
