IC2118 -Witch Head Nebula (Hairy Blue at right)
As the name implies, this reflection nebula associated with the star Rigel looks suspiciously like a fairy-tale crone. Formally known as IC 2118 in the constellation Orion, the Witch Head Nebula glows primarily by light reflected from the star. The color of this very blue nebula is caused not only by the blue color of its star, but also because the dust grains reflect blue light more efficiently than red. A similar physical process causes Earth's daytime sky to appear blue.

Star Rigel (Giant Blue Star in centre)
Rigel is a blue supergiant that is the brightest star in the constellation Orion (the Hunter). Due to its measured size and brightness, it is expected to end in a supernova one day. It also has two known companions, Rigel B and Rigel C.
............
Partial Barnard Loop (red emission)
Barnard's Loop is an emission nebula in the constellation of Orion. It is part of the Orion Molecular Cloud Complex which also contains the dark Horsehead and bright Orion nebula. The loop takes the form of a large arc centered approximately on the Orion Nebula.
