说明: 天空中那怪异的棕色带状物是什么? 在观测星团NGC 4372[3]时,观测者常会注意到附近有一条绵延约3度[4]的不寻常暗带。 这条暗带,其实是有暗饰带星云之称的颀长分子云[5]。 而这张照片所呈现的暗饰带星云[6],横亘在一片多彩的富星场中央。 这团星云的暗沉色泽,来自于能轻易散射可见光[7]的高密度星际尘埃[8]。 照片左侧的模糊的泛白光斑[9]就是球状星团[10]NGC 4372,而星团右上方的泛蓝亮星则是苍蝇座γ[11]。 使用高倍率的双筒望远镜[12],可以在南天[13]的苍蝇[14] 座[15]方向找到暗饰带星云[16]。 (Dark Doodad Nebula 暗饰带星云; “Doodad” 不知名的东西[17]、那个什么东西.[18])
