The Cocoon Nebula, or IC 5146, is an emission nebula located about 4000 light years away in the constellation Cygnus.
emission nebulae and reflection nebulae.
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.
The types of nebulae that exist in the universe include bright, dark and emission nebulae. Different nebulae are often named for their shape. More information can be found on "Sea and Sky".
A nebula is a region of interstellar gas and dust. Emission nebulae are clouds of ionized gas that allow red, blue, and violet light through. Generally, these nebulae appear reddish. Reflection nebulae are clouds of dust that simply reflect light from nearby stars. The dust particles of reflection nebulae usually only scatter blue light, so the appearance is blue. Other types of nebulae don't reflect light. Dark nebulae such as the Horsehead Nebula are so dense that they block light from other sources, such as background emission nebulae, reflection nebulae, or other stars.
An A+ emission nebulae formation is lit from within.
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.

it depends on how large the nebulae is. The largest of nebulae (in both distance and height) form the largest number of stars while the smallest of nebulae (in both distance and height) form the least number of stars. Therefore there is no fixed number for the number of stars that can be formed from a single nebulae (a variable amount of stars can be formed from one nebulae)
