Witch Head Nebula
The Witch Head Nebula (IC 2118) is a very large, faint reflection nebula in the constellation Eridanus that shines primarily by light reflected from Rigel, which lies 2.6° to the west. Its bluish hue is caused not only by Rigel's color but also because dust grains in the nebula reflect blue light more efficiently than they do red.
