a nebula is one nebula. nebulae are 2 or more nebulas.
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)
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.
yes, there are the nebulae, black holes, and planets, but mostly the space in between the stars is nothingness
The main types of nebulae are emission nebulae, reflection nebulae, dark nebulae, and planetary nebulae. Emission nebulae glow with their own light, often due to hydrogen gas being ionized by nearby stars. Reflection nebulae reflect light from nearby stars. Dark nebulae are dense clouds of dust that obscure light. Planetary nebulae are the ejected outer layers of dying 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.
Nebulae are not stars. They are clouds of dust, hydrogen, helium, and other ionized gases in space where stars are born. Some nebulae can be observed because of the light of nearby stars reflecting off their gas and dust.
Nebulae are large clouds of dust and gas in space where stars are born. Within a nebula, gravitational forces can cause the gas and dust to collapse and form a protostar, which eventually ignites nuclear fusion and becomes a star. Therefore, nebulae are the birthplaces of stars, and stars are formed from the material within nebulae.
Nebulae
The two types of bright nebulae are emission nebulae and reflection nebulae. Emission nebulae are clouds of gas that emit their own light due to ionization by nearby hot stars, creating vibrant colors. In contrast, reflection nebulae do not produce their own light but instead reflect light from nearby stars, often appearing blue due to the scattering of shorter wavelengths. Together, these nebulae play crucial roles in the formation and evolution of stars.
Bright nebula are clouds of gas and dust that shine by reflected starlight. Dark nebula are clouds of dust and colder gas that can be seen by their silhouette against brighter objects behind them in the line of sight.
*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
