This is not the more famous Horsehead nebula toward Orion but rather a fainter nebula that only takes on a familiar form with deeper imaging. The main part of this imaged molecular cloud complex is a reflection nebula catalogued as IC 4592.
Reflection nebulas are actually made up of very fine dust that normally appears dark but can look quite blue when reflecting the light of energetic nearby stars. In this case, the source of much of the reflected light is a star at the eye of the horse. (In fact if you look closer you will note two stars). That star is part of Nu Scorpii, one of the brighter star systems toward the constellation of the Scorpion (Scorpius).
