IC 4592: The Blue Horsehead Reflection Nebula
Explanation: Do you see the horse's head? What you are seeing is not the famous
Horsehead nebula toward
Orion but rather a fainter nebula that only takes on a
familiar form with deeper imaging. The main part of the
here imaged molecular cloud complex is a
reflection nebula cataloged 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
visible 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. That star is part of
Nu Scorpii, one of the brighter star systems toward the constellation of the Scorpion (
Scorpius). A second
reflection nebula dubbed
IC 4601 is visible surrounding
two stars to the right of the image center.
