IC2118 - WitchHead Nebula


Resolutions Available: 800x600 : 1600x1200 : 2400x1800
         Object WitchHead Nebula
         Comment A sinister shaped figure known as the WitchHead Nebula (IC2118) resides in the constellation Eridanus. The nebula primarily glows due to the reflected light from the bright star Rigel located 2.6 degrees away in the constellation Orion (seen top right of frame). The blue hues are due to the dusty characteristics of the nebula as dust reflects blue light more efficiently than red light. This is in contrast to the interstellar reddening phenomenon where dust suppresses blue light near the center of our Milky Way galaxy. The WitchHead Nebula resides approximately 1,000 light years away.
