Full Frame

The main part of the above 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 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 on in the horses
neck region lower right.
