Explanation: This cosmic close-up looks deep inside the Soul Nebula. The dark and brooding dust clouds near the top, outlined by bright ridges of glowing gas, are cataloged as IC 1871. About 25 light-years across, the telescopic field of view spans only a small part of the much larger Heart and Soul nebulae. At an estimated distance of 6,500 light-years the star-forming complex lies within the Perseus spiral arm of our Milky Way Galaxy, seen in planet Earth’s skies toward the constellation Cassiopeia. An example of triggered star formation, the dense star-forming clouds in the Soul Nebula are themselves sculpted by the intense winds and radiation of the region’s massive young stars. In the featured image, stars have been digitally removed to highlight the commotion in the gas and dust.

说明: 这幅特写影像呈现灵魂星云的深处。影像顶端的黝黑阴郁、镶着明亮云气脊的尘埃云，编录号为IC 1871。这片约25光年宽的望远镜视野，只涵盖远更广袤的心与魂星云的一小部分。这个距离约6,500光年的恒星形成区复合体，从地球看出去位在仙后座方向的银河系英仙臂内。在灵魂星云内，受到外力触发而​​形成恒星的致密云气，本身也受到此区大质量年轻恒星的恒星风和辐射之雕塑。在这幅主题影像里，恒星使用数位技术予以移除，以突显湍动的气体和尘埃。
