Nebulae

Upon hearing that people come from dust and return to dust, a little girl said, "Well, somebody's either coming or going under my bed."

Nebulae are clouds of dust and gas.  A planetary nebula is expelled from a star in the process of dying. Other nebulae provide the material for the birth of new stars. This page is a collection of the latter type of nebulae. See the Stars page for planetary nebulae.
