a nebula is one nebula. nebulae are 2 or more nebulas.
a nebula is a large amount of gas and dust spread out in an immense volume that makes up a star while a prostar is the earliest stage of a star.
Protostars form out of nebulars. Nebulars are thin clouds of interstellar gas, Protostars are condensations of this gas (pulled together by gravity) into quasi solid objects of the size of a Sun.
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.
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)
yes, there are the nebulae, black holes, and planets, but mostly the space in between the stars is nothingness

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.
Nebulae are not stars. They are places where stars are formed, so a single nebula would contain lots of stars.
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.
Becuase nebulae tell us how stars get formed so the composition, density and size of a nebulae cloud says a lot about its age, likelihood of stars forming and the type of stars that might form.
Nebulae
*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
