下面这些东西有什么共同之处：圆锥体、狐狸的皮毛和圣诞树？答案：它们都发生在独角兽星座（麒麟座）。被认为是一个恒星形成区，编号为NGC 2264，宇宙气体和尘埃的复杂混乱距离大约2700光年，混合了由新生恒星的高能光激发的红色发射星云和黑暗的星际尘埃云。这张特色图像的角度比满月还大，覆盖了距离NGC 2264超过50光年的区域。它的宇宙角色包括狐狸毛皮星云，其卷曲的毛皮位于图像中心的左侧，在狐狸毛皮右侧可见的明亮变星S Mon，以及靠近图像顶部的锥状星云。锥状星云位于其顶峰，该区域整体发光的形状给了它“圣诞树星团”的绰号，那里的星星是树上的装饰品。探索你的宇宙：随机APOD生成器

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.
