圓錐體、狐狸毛和聖誕樹有什麼共同點? 答案是:它們都出現在獨角獸星座(Monoceros)。 這個複雜的宇宙氣體和塵埃混雜區被認為是一個恆星形成區,被編入 NGC 2264 星系,距離約 2 , 700 光年,由新生恆星發出的高能光激發的紅色發射星雲與黑暗的星際塵埃雲混合在一起。特寫影像的角度比滿月還要大,在 NGC 2264 的距離上覆蓋了 50 多光年。其中的宇宙角色包括狐狸毛星雲(其捲曲的毛皮位於影像中心左側)、狐狸毛右側可見的明亮變星 S Mon,以及影像頂部附近的錐狀星雲。 錐狀星雲位於頂端,該區域的整體光暈形狀使它獲得了 "聖誕樹星團 "的暱稱,恆星就是聖誕樹上的裝飾品。 探索你的宇宙隨機 APOD 生成器
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). 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.
