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.
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.
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.
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.
A cluster of stars and a nebulae together is often referred to as a stellar nursery. These regions are where new stars are born out of clouds of dust and gas.
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.
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)
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
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.

*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
The formation of new stars can be triggered by the shock waves and turbulence generated by supernovas, which compress gas and dust, leading to new star formation. Planetary nebulae are formed from the outer layers of certain types of stars when they reach the end of their life cycle. These nebulae can enrich the surrounding interstellar medium with elements necessary for forming new stars.
A cluster of stars and a nebulae together is often referred to as a stellar nursery. These regions are where new stars are born out of clouds of dust and gas.
Stars form in a nebulae
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.
They all do. Well, technically, nebulae produce stars.
