About this Image

Clouds of reddish glowing hydrogen gas and blue reflection areas fill this colorful skyscape in the constellation Monoceros, the Unicorn. A star forming region cataloged as NGC 2264, the complex jumble of cosmic gas and dust is about 2,700 light-years distant and mixes reddish emission nebulae excited by energetic light from newborn stars with dark interstellar dust clouds.

At the top left side of the image there is the Cone Nebula, which gets its unique name from the large cone shaped dark nebula, the bright tip of the Cone is lit up by, and blocks the light from a nearby hot blue star. The complex complex structures are formed by stellar winds and condensation of dust. The fine bows are Herbig Haro objects.
North is to the right.
