NGC 6914 is a complex of reflection nebulae at the heart of the constellation Cygnus. This region concentrates gaseous and dusty masses of the galactic plane, where stars are born. Fragments of nebula situated between the Earth and the young stars appear to be dark, with varying opacities and intricate shapes. In other areas, near the younger and hotter stars, dust shines with the bluish colors of the reflection nebulas. Lastly, all the image is covered by ionized hydrogen that gives to the scene a reddish and warm backdrop. Newly born stars, which are only a few million years old, mill around the scene. Their colors reveal their diversity of masses and temperatures. But in this small portion of the Galaxy, about 6,000 light-years away, massive and hot stars (O and B type stars) are so abundant that the area is classified as an OB association. Its name is Cygnus OB2.
