Witch Head Nebula (IC 2118). It's reflection nebula which glows by reflecting light from the bright blue star Rigel in the constellation Orion. The nebular dust grains tend to absorb red light and reflect blue light. (Image credit: Steve Mazlin, Star Shadows Remote Observatory) Mona Evans, "Cosmic Halloween Tour"

Ghost-Like Nebula Credit: NASA, ESA, Hubble, R. Sahai (JPL) [Full Story]The ghost-like nebula, IRAS 05437+2502, includes a small star-forming region filled with dark dust that was first noted in images taken by the IRAS satellite in infrared light in 1983. This recently released image from the Hubble Space Telescope shows many new details, but has not uncovered a clear cause of the bright sharp arc.
