An emission nebula is a cloud of plasma emitting light in many colors.

Because most of the universe is made of hydrogen, many emission nebulae appear red.

N44 is classified as an emission nebula because it contains large regions of ionized hydrogen.

This is an emission nebula showing glowing gas and darker dust lanes.

In many emission nebulae, an entire cluster of young stars is doing the work.

Sharpless 2-115 is another emission nebula with a complex pattern of light and dark patches.

They can be seen as dark clouds against bright emission nebulae or background stars.

For many years, well into the 1960s, it was thought to be an bright emission nebula.

Usually the gases in an emission nebula are ionized.

Notably missing are pinkish emission nebulae indicative of new star birth.
