Cygnus Molecular Nebula Complex
The Cygnus Molecular Nebular Complex (also known simply as the Swan Complex) is a giant molecular cloud located in the heart of the boreal Milky Way, in the direction of the Cygnus (constellation), constellation Cygnus. It is one of the most turbulent Star formation, star-forming areas in the Milky Way Galaxy and its largest known molecular nebula complex. Within it are several H II regions, vast and brilliant stellar associations, open clusters, and a large number of some of the brightest stars in the galaxy. The most notable structure in the complex is known by the Astronomical catalogue, catalog abbreviation Sharpless catalog, Sh2-109; it is a vast ensemble, spanning hundreds of light-years, of H II regions, ionized by very bright stars, raddensated in the various OB Association found in this area of the sky. Sh2-109 is also the brightest and most prominent part of the huge molecular nebula complex known as Cygnus X; the total mass of gas and dust in this region is between 10,0 ...

Cygnus (constellation)
Cygnus is a northern constellation on the plane of the Milky Way, deriving its name from the Latinisation of names, Latinized Greek language, Greek word for swan. Cygnus is one of the most recognizable constellations of the northern summer and autumn, and it features a prominent asterism (astronomy), asterism known as the Northern Cross (asterism), Northern Cross (in contrast to the Southern Cross). Cygnus was among the 48 constellations listed by the 2nd century astronomer Ptolemy, and it remains one of the 88 modern constellations. Cygnus contains Deneb (ذنب, translit. ''ḏanab,'' tail)one of the brightest stars in the night sky and the most distant first-magnitude staras its "tail star" and one corner of the Summer Triangle the constellation forming an east pointing Altitude (triangle), altitude of the triangle. It also has some notable X-ray sources and the giant stellar association of Cygnus OB2. One of the stars of this association, NML Cygni, is one of the List of larg ...
