IC 2118 (also known as Witch Head Nebula due to its shape), is believed to be an ancient supernova remnant or gas cloud illuminated by nearby supergiant Rigel in Orion. It lies in the Eridanus constellation, about 1000 light-years from Earth. The nature of the dust particles, reflecting blue light better than red, is a factor in giving the Witch Head its blue color.
