Explanation: Strange shapes and texturescan be found in neighborhood of the Cone Nebula. The unusual shapes originate from fine interstellar dust reacting in complex ways with the energetic lightand hot gas being expelled by the young stars. The brightest star on the rightof the featured picture is S Mon, while the region just below it has beennicknamed the Fox Fur Nebula for its color and structure. The blue glowdirectly surrounding S Mon results from reflection, where neighboring dustreflects light from the bright star. The red glow that encompasses the wholeregion results not only from dust reflection but also emission from hydrogengas ionized by starlight. S Mon is part of a young open cluster of stars namedNGC 2264, located about 2500 light years away toward the constellation of theUnicorn (Monoceros). Even though it points right at S Mon, details of theorigin of the mysterious geometric Cone Nebula, visible on the far left, remaina mystery.
锥状星云的附近
在锥状的星云附近能够看到一些拥有奇怪形状和纹理的结构。这些不寻常的结构是由细小的星际尘埃和年轻恒星释放的高能星光和炽热气体以复杂的方式相互作用而产生的。这幅照片右侧最亮的星是S Mon，而它下方的区域因颜色和结构特征被昵称为狐皮星云。S Mon周围的蓝色辉光是附近尘埃反射了明亮恒星的星光所致。环绕整个区域的红色辉光不仅来自尘埃反射，还来自于被星光电离的氢气辐射。S Mon是年轻疏散星团NGC 2264的一部分，位于麒麟座方向，距离地球约2500光年。尽管照片最左侧可见的神秘锥状星云正好指向S Mon，但该区域的细致结构仍是迷雾重重。
