Explanation: Cosmic clouds form fantastic shapes in the central regions of emission nebula IC 1805. The clouds are sculpted by stellar winds and radiation from massive hot stars in the nebula’s newborn star cluster, Melotte 15. About 1.5 million years young, the cluster stars are scattered in this colorful skyscape, along with dark dust clouds in silhouette against glowing atomic gas. A composite of narrowband and broadband telescopic images, the view spans about 15 light-years and includes emission from ionized hydrogen, sulfur, and oxygen atoms mapped to green, red, and blue hues in the popular Hubble Palette. Wider field images reveal that IC 1805’s simpler, overall outline suggests its popular name – the Heart Nebula. IC 1805 is located about 7,500 light years away toward the boastful constellation Cassiopeia.

说明: 在发射星云IC 1805中心之处的宇宙云，拥有各种奇特的形状。而雕塑出这些云气的，则是星云内刚诞生星团Melotte 15（梅洛特15）的大质量热星之恒星风和辐射。这些稚龄约150万年的星团成员星与及位在原子辉光前方的剪影状黝黑尘埃云，散布这片彩色星野里。这张结合窄与宽波段数据的望远镜影像，跨幅约为15光年，其中，来自电离氢、硫和氧原子的光，依据哈勃望远镜著名的色表，分别以绿、红和蓝色阶加以着色。更大视野的影像，会清楚显示为何星云IC 1805的简单轮廓，会让它博得心脏星云的雅号。IC 1805位在仙后座方向，离我们约有7,500光年远。
