英文原文:Explanation: This cosmic close-up looks deep inside the Soul Nebula. The dark and brooding dust clouds outlined by bright ridges of glowing gas are cataloged as IC 1871. About 25 light-year s 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 the Milky Way , seen in planet Earth's skies toward the constellation of the Queen of Aethiopia ( Cassiopeia ). An example of triggered star formation , the dense star-forming clouds of IC 1871 are themselves sculpted by the intense winds and radiation of the region's massive young stars. This color image adopts a palette made popular in Hubble images of star-forming regions. 说明: 这张宇宙特写[2]深入展现了灵魂星云的内部。 由明亮气体辉光勾勒出黑暗阴郁的尘埃云被编录为 IC 1871。 这片星云的直径约为25光年[3],但望远镜的视野仅覆盖了更大的心脏星云和灵魂星云[4]的一小部分。 这个恒星形成复合体位于银河系的英仙座旋臂中,距离地球约 6,500 光年,从地球的天空中可以看到它位于仙后座[5],即埃塞俄比亚[6]女王(仙后座[7])的方向。 IC 1871是触发恒星形成[8]的一个例子,其密集的恒星形成云本身是由该区域大质量年轻恒星的强烈恒星风[9]和辐射[10]所塑造而成的。 这幅彩色图像采用了哈伯望远镜图像中最常见的色彩调色板[11]来呈现恒星形成区域。
