Orion Nebula in Oxygen, Hydrogen, and Sulfur Image Credit Copyright: César Blanco González The Orion Nebula is among the most intensely studied celestial features.The nebula has revealed much about the process of how stars and planetary systems are formed from collapsing clouds of gas and dust. Astronomers have directly observed protoplanetary disks, brown dwarfs, intense and turbulent motions of the gas, and the photo-ionizing effects of massive nearby stars in the nebula.
The bipolar star-forming region called Sharpless 2-106. The 'wings' of the nebula record the contrasting imprint of heat and motion against a backdrop of a colder medium. Twin lobes of super-hot gas stretch outward from the central star. This hot gas creates the 'wings.' A ring of dust & gas orbit-ing the star acts like a belt, clinching the expending nebula into an 'hourglass' shape. In Cygnus
