| The Eagle Nebula (M16) consists of enormous columns of cool interstellar hydrogen gas and dust that are about 7,000 light-years from Earth (in the constellation Serpens). This star-forming cloud is illuminated by ultraviolet light that is emitted from newborn stars. The columns are called EGG's (Evaporating Gaseous Globules) because the ultraviolet light boils off some of the hydrogen gas (H2), shaping the nebula in a process called photoevaporation. The biggest column is about 1 light-year tall. |
