You can get this picture in original resolution at https://www.jpl.nasa.gov/images/pia25434-orion-nebula-in-infrared. I use this picture as one of the collections of 4K space wallpapers. The Orion Nebula is a diffuse nebula situated in the Milky Way. It is known as the middle “star” in the “sword” of Orion.
