Witch Head Nebula (IC 2118). It's reflection nebula which glows by reflecting light from the bright blue star Rigel in the constellation Orion. The nebular dust grains tend to absorb red light and reflect blue light.

Formally known as IC 2118 in the constellation Orion, the Witch Head Nebula glows primarily by light reflected from the star. The color of this very blue nebula is caused not only by blue color of its star, but also because the dust grains reflect blue light more efficiently than red...
