星星正在埃塞俄比亚女王的灵魂中形成。更具体地说，在仙后座的方向可以找到一个被称为灵魂星云的大恒星形成区，希腊神话认为仙后座是很久以前统治尼罗河上游土地的国王的虚荣妻子。灵魂星云也被称为westhour 5 (W5)，它拥有几个被宇宙尘埃遮蔽的星团、脊状和柱状星团，以及由年轻大质量恒星的风形成的巨大的真空气泡。灵魂星云位于6500光年之外，跨度约100光年，通常与它的天体邻居心脏星云（IC 1805）合照。这张特色图片是由不同颜色的曝光组合而成：红色是氢气发出的，黄色是硫磺发出的，蓝色是氧气发出的。

Stars are forming in the Soul of the Queen of Aethopia. More specifically, a large star forming region called the Soul Nebula can be found in the direction of the constellation Cassiopeia, whom Greek mythology credits as the vain wife of a King who long ago ruled lands surrounding the upper Nile river. Also known as Westerhout 5 (W5), the Soul Nebula houses several open clusters of stars, ridges and pillars darkened by cosmic dust, and huge evacuated bubbles formed by the winds of young massive stars. Located about 6,500 light years away, the Soul Nebula spans about 100 light years and is usually imaged next to its celestial neighbor the Heart Nebula (IC 1805). The featured image is a composite of exposures made in different colors: red as emitted by hydrogen gas, yellow as emitted by sulfur, and blue as emitted by oxygen.
