Sorry, but this doesn't make sense!
For a start, 'nebulae' is plural. And Cygnus isn't in a nebula. Cygnus (like all the constellations) is just a name given to a region of sky that appears to resemble some object or other from the arrangement of its stars. None of the stars in a given constellation usually have any connection with the others. They just lie in the same general direction. Deneb, the brightest star in Cygnus, is over 1000 lightyears away, but close to it (in the sky!) we have 61 Cygni, which is one of the closest stars to us, at about 11 lightyears.
A constellation is a purely human construct, like (say) a country with its borders.
Planetary nebulae (the cat's eye nebula) Emission nebulae (the orion nebula) Dark nebulae (the horsehead nebula) Supernova remnant nebulae (the crab)
Ionized hydrogen and helium are the most abundant chemical elements in nebulae.
Which one - there are hundreds of stars in the Cygnus constellation
Cygnus is the swan.
It is believed that there is a black hole in the constellation of Cygnus (the Swan), the strong X ray source Cygnus X-1 is believed to be a binary system where one component is a black hole. (see the link Below).There is also a super-massive black hole in the center of our galaxy (the Milky Way) this is to be found in the constellation of Sagittarius and is called Sagittarius A*. (see the link below).
Yes, a lot. For example the Cocoon nebula, the North America Nebula, the Pelican Nebula, the Veil Nebula and the Crescent Nebula. In addition to the nebulae, Cygnus has binary stars, exoplanets, the X-ray source Cygnus-X1, etc.
The Cocoon Nebula, or IC 5146, is an emission nebula located about 4000 light years away in the constellation Cygnus.

In astronomy, diffuse nebulae is the general term for illuminated nebulae. The three types of diffuse nebulae are reflection nebulae, emission nebulae and supernova remnants. They are diffuse as opposed to the non-diffuse dark nebulae, i.e. the particles have spread out.
Cygnus is not a constellation of the zodiac.
Cygnus is Latin for swan.
cygnus mean swan
The name of the constellation is cygnus.
