The Lion Nebula (also known as Sh2-132) is a weak emission nebula near the constellations of Cepheus and Lacerta. It’s thought to be about 10,000 light years away in the Arm of Perseus within the Milky Way. The main components of this emission nebula are hydrogen and oxygen gases, which are stimulated to a high energy state by ultra violet light from nearby stars and subsequently re-emit the light. The stars responsible for ionizing its gases are very hot and massive, including two Wolf-Rayet stars (HD 211564, HD 211853). The darker areas are “dark nebulae,” which are dust clouds that obscure light.
