The W40 star-forming region is projected on the sky in the direction of the Serpens-Aquila Rift, a mass of dark clouds above the Galactic plane in the constellations Aquila, Serpens, and eastern Ophiuchus.
The high extinction from interstellar clouds means that the nebula looks unimpressive in visible light, despite being one of the nearest sites of massive star formation.
