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 correct term is nebulae. a nebulae is a could of many gases and dust, where stars are created. TYPES: Diffuse Nebulae- the most common type. it is interstellar, which means among the stars, and not part of any galaxy. Planetary Nebulae- completely unrelated to planets. planetary nebulae is when gas and plasma are formed after certain types of stars die. it sometimes looks like gas planets, like neptune and uranus, hence the name. Reflection Nebulae- clouds of dust that reflect the light of nearby stars, though they are not nebulae, because they do not create stars. Protoplanetary Nebulae- a point in the lifetime of an astronomical object (star). protoplanetary nebulae, or preplanetary nebulae, emit light, much like reflection nebulae Emission Nebulae- a could of ionized gas which emits colorful lights

emission nebulae and reflection nebulae.
Planetary nebulae (the cat's eye nebula) Emission nebulae (the orion nebula) Dark nebulae (the horsehead nebula) Supernova remnant nebulae (the crab)
an emission nebulae is an object from space
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.
planetary nebulae are formed by dying red stars.
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".
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)
Nebulae are found in various places throughout every galaxy.
Nebulae - band - was created in 1992.
Technically, no nebulae are luminous. The ones that appear as such have stars either within or near them, and the nebulae merely reflect the light emitted by these stars.
An A+ emission nebulae formation is lit from within.
* Gases diffuse. * Liquid diffuse.
a nebula is one nebula. nebulae are 2 or more nebulas.
Nebulae are made of clouds of hydrogen and other elements or clouds of dust (dark nebulae)
the horse head nebulae is 1500 light years away from earth
Ionized hydrogen and helium are the most abundant chemical elements in nebulae.
Horsehead Nebula doesn't glow like other nebulae because it is older than other nebulae and was probably a lot smaller. In addition, Horsehead Nebula is farther away from the Earth than other nebulae, so it may seem that it doesn't glow as bright as other nebulae. No, this isn't right! The horsehead nebula doesn't glow for one reason - it isn't illuminated by any stars whose energy is enough to make the gas shine. That's the only difference between a 'bright' diffuse nebula (like M42) and a 'dark' one like the Horsehead or the Coalsack. M42 (the Orion nebula) is bright because there are several hot, energetic stars embedded inside it, and which cause it to 'shine'.
A nebula is a region of interstellar gas and dust. 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. Other types of nebulae do reflect light. 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.
