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-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 the Milky Way, seen in planet Earth’s skies toward the constellation 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.

這幅宇宙特寫圖像深入探訪靈魂星雲(Soul Nebula)。暗黑而神秘的塵埃雲,被明亮的發光氣體輪廓勾勒出來,這些雲朵被編號為IC 1871。IC 1871的直徑約25光年,這幅望遠鏡拍攝的視野僅覆蓋了更大心靈與靈魂星雲(Heart and Soul Nebula)的一小部分。這個星際形成複合體估計距離地球約6,500光年,位於銀河系的仙女座臂(Perseus spiral arm),在地球的天空中朝向仙后座(Cassiopeia)觀賞。IC 1871是觸發星際形成的例子,其密集的星形成雲受到該區域年輕巨大恆星所釋放的強風和輻射的雕刻。這幅彩色圖像採用了哈勃太空望遠鏡(Hubble)在星際形成區域中流行的顏色調色板。
