Witch Head Nebula (IC 2118)
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.
