Nebulae contain gases such as hydrogen, helium, and trace amounts of heavier elements like carbon, oxygen, and nitrogen. These gases are the building blocks from which stars and planetary systems form. Additionally, other elements and molecules may be present in nebulae, contributing to their varying compositions and colors.
The two main types of bright nebulae are emission nebulae, which emit light from ionized gases, and reflection nebulae, which reflect light from nearby stars. Emission nebulae are usually red or pink in color, while reflection nebulae appear blue due to scattering of light.
Emission nebulae are nebulae that are lit from within. They are made up of ionized gases that emit light of various colors depending on the elements present in the nebula. The light comes from the recombination of electrons with protons in the ionized gas.
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 composed mainly of dust, gases, and plasma (ionized particles). The specific composition can vary depending on the type of nebula, but common elements found in nebulae include hydrogen, helium, carbon, oxygen, and nitrogen. These elements are the building blocks for stars and planets.
Nebulae have different colors because of the type of gases they contain and the way they interact with surrounding light. Hotter gases tend to emit blue and ultraviolet light, while cooler gases emit red and infrared light. Dust particles can also scatter light, creating different hues in a nebula.

*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
You see million years ago there was a HUGE clump of gases which they call "nebulae" well the gases formed together and then came are star the Sun.
Stars are often born in nebulae composed of interstellar gases called stellar nurseries.
