Summary

Description

English: This reflection nebula is associated with the bright star Rigel in the constellation Orion. Known as IC 2118, the Witch Head Nebula glows primarily by light reflected from Rigel, located just outside the top right corner of the image. Fine dust in the nebula reflects the light. The blue color is caused not only by Rigel's blue color but because the dust grains reflect blue light more efficiently than red. The nebula lies about 1000 light-years away. Cross identification: NGC 1909, IC 2118, LBN 959, CED 41, Witch Head nebula ( SEDS )
