Orion Nebula in Oxygen, Hydrogen, and Sulfur Image Credit Copyright: César Blanco González, The Orion Nebula spans about 40 light years and is located about 1500 light years away in the same spiral arm of our Galaxy as the Sun. The Great Nebula in Orion can be found with the unaided eye just below and to the left of the easily identifiable belt of three stars in the popular constellation Orion. The above image shows the nebula in 3 colors specifically emitted by hydrogen, oxygen sulfur gas.
This is probably the most amazing photo you will see of the Orion nebula's center, a cloud of gas and dust known as M42. The work was created by Adam Block at the Mount Lemon Sky Center observatory in Arizona. Image: Adam Block/Mount Lemmon SkyCenter/University of Arizona
