Orion nebula. Artwork of the Orion nebula (M42) seen from a moon orbiting a nearby planet. The Orion nebula is a huge starbirth region around 1300 light years from Earth. It consists of hydrogen gas that is ionised and illuminated by the radiation from hot young stars within it. The stars formed due to the gas collapsing under its own gravity, until it became hot and dense enough for nuclear reactions to begin.
