Lurking in the space between Orion the Hunter and his dog lies a stellar nursery. Much of it is only visible in X-ray. A faint outline is visible in broadband (ordinary) light that can be teased out with long exposures, but narrowband is what really makes it pop. This image was produced by combining the data from a broadband imaging session with data from narrowband filters that reveal hydrogen-alpha, oxygen III and sulfur II emissions. It shows the amazing detail of the interstellar gas and molecules that feed the birth of new stars at its center. This is the Rosette Nebula.
