Nebulae

Nebulae

Nebulae are the often beautiful objects formed by clouds of interstellar gasses. These clouds are usually formed during some part of the death of a star. The three main types of nebulae are the planetary nebulae, the ionized hydrogen region and the supernova remnants. Planetary nebulae are formed as a dying star sloughs off matter. Ionized hydrogen regions usually occur whenever large quantities of gas get near the large O-type stars. Supernova remnants are the spherical shells of matter which have blown off a large exploding star. [TB] {EA}
