Orion nebula. Artwork of the Orion nebula (M42 & M43). M43 (NGC 1982,lower right) is a smaller part of the nebula,separated from M42 (NGC 1976) by a dark band of dust. The Orion nebula is a huge cloud of gas and dust which glows due to the ionisation of the hydrogen it contains by ultraviolet radiation from hot young stars within it. These stars form a cluster known as the Trapezium,contained within M42. The Orion nebula is the nearest large emission nebula (or HII region) to Earth,lying 1500 light years away in the constellation Orion | |
