The Witchhead Nebula (IC2188) by Michael Sidonio
About 900 light years away, this faint molecular cloud lies in the constellation Eridanus, but it is lit up by the brilliant giant blue-white star Rigel, the brightest star in Orion and the seventh brightest star in the sky. Faint red hydrogen emission also permeates the whole scene. This nebula glows with soft blue light, a result of the star's light reflecting off its dust particles.
The profile of a witch's face is clearly seen in the cloud, complete with straggly hair, big eye sockets, a hooked nose, an open mouth, and a big chin.
