The pinkish-red color of nebulae, such as M42 in Orion or the Lagoon Nebula in Sagittarius, is really a combination of four different bright spectral lines of hydrogen gas. A hydrogen atom has a single proton at its center and a single electron in its outer region.
A nebula (Latin for cloud; pl. nebulae, nebulae, nebulÃ¦ or) nebulas is an interstellar cloud of, dust, hydrogen helium and other ionized. Gases, originally nebula was a name for any diffuse astronomical, object including galaxies beyond The Milky. wayxamples of these types of nebulae are the Rosette Nebula and the Pelican Nebula. The size of these nebulae, known as HII regions, varies depending on the size of the original cloud of gas. New stars are formed in the nebulae.
