NGC 2170, the Angel Nebula

NGC 2170, the Angel Nebula, is a reflection/emission nebula in the constellation Monoceros. This region of sky is heavily obscured by interstellar dust, which is home to several bright nebulae. (The Sky Live)

The dark brown and almost black clouds, that form the background and central regions of the image, are dark nebulae or absorption nebulae. These nebulae are molecular clouds, composed primarily of molecular hydrogen, H2. Molecular clouds are stellar nurseries.
