Seen toward the celestial equator and near the plane of our Milky Way galaxy, the seasonal skyscape mixes reddish emission nebulae excited by energetic light from newborn stars with dark interstellar dus t clouds. Where the otherwise obscuring dust clouds lie close to the hot, young stars, they also reflect starlight, forming blue reflection nebulae. In fact, br ight variable star S Monocerotis is immersed in a blue-tinted haze near center. Arrayed with a simple triangular outline above S Monocerotis, the stars of NGC 2 264 are popularly known as the Christmas Tree star cluster. Carved by energetic starlight, the Cone Nebula sits upside down at the apex of this cosmic Christmas tree while the dusty, convoluted pelt of glowing gas and dust under the tree is called the Fox Fur Nebula. This rich telescopic frame spans about 1.5 degrees o r 3 full moons on the sky top to bottom, covering nearly 80 light-years at the d istance of NGC 2264.","hdurl":"https:\/\/apod.nasa.gov\/apod\/image\/2512\/IMG_7 311.jpeg","media_type":"image","service_version":"v1","title":"Unicorn, Fox Fur and Christmas Tree","url":"https:\/\/apod.nasa.gov\/apod\/image\/2512\/IMG_7311_ 800.jpeg"}
