🌟你知道嗎？圓錐、狐狸毛和聖誕樹有什麼共同點？它們都出現在獨角獸座（Monoceros）內！這個名為NGC 2264的星雲區域位於距離我們約2,700光年，充滿了宇宙中的氣體和塵埃，伴隨著新生恆星所發出的強烈光線，形成了紅色的發射星雲和黑暗的星際塵雲。
這幅影像展示了大約30光年的範圍（相當於滿月的直徑），其中包含了狐狸毛星雲（Fox Fur Nebula）和圓錐星雲（Cone Nebula）。在影像左側的圓錐星雲以及右側的明亮變星S Mon之間，星星的分布形成了聖誕樹星團（Christmas Tree star cluster），呈現出三角形的樹形。

原文:
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). Pictured 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. Where the otherwise obscuring dust clouds lie close to the hot, young stars they also reflect starlight, forming blue reflection nebulae. The image spans about the diameter of a full moon, covering about 30 light-years at the distance of NGC 2264. Its cast of cosmic characters includes the Fox Fur Nebula, whose convoluted pelt lies on the lower right, bright variable star S Mon visible just above the Fox Fur, and the Cone Nebula on the image left. Given their distribution, the stars of NGC 2264 are also known as the Christmas Tree star cluster. The triangular tree shape traced by the stars appears here with its apex at the Cone Nebula on the left with its broader base near S Mon on the right.
