IC2118 also known as “WitchHead” nebula, wafts through space at a nearby 1000 light years away. The star Rigel, Orion's luminous limb, lights up this nebula blue both by its own color and scattered light in the dust of this nebula. Hints of red also permeate the field showing that some of the gas is excited by the starlight.
