What do the following things have in common: a cone, the fur of a fox, and a Christmas tree? Answer: they all occur in the constellation of the Unicorn (Monoceros). Considered as a star forming region and 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. The featured image spans an angle larger than a full moon, covering over 50 light-years at the distance of NGC 2264. Its cast of cosmic characters includes the Fox Fur Nebula, whose convoluted pelt lies just to the left of the image center, bright variable star S Mon visible just to the right of the Fox Fur, and the Cone Nebula near the image top. With the Cone Nebula at the peak, the shape of the general glow of the region give it the nickname of the Christmas Tree Cluster, where stars are tree ornaments.
