天鹰座裂谷（Aquila Rift）是分隔我们银河系拥挤平面的黑暗广阔的一部分，它在明亮的牵牛星附近穿过地球的天空。在银河系暗淡的星光映衬下，它的尘埃分子云可能含有形成数十万颗恒星的原料，天文学家在这些乌云中寻找恒星诞生的蛛丝马迹。这张用望远镜拍摄的特写镜头看到的是一片破碎的天鹰座黑云复合体，编号为LDN 673，它横跨的视野比满月略宽。在这幅图中，可以看到与年轻恒星相关的高能流出物的迹象，包括中央上方和右侧的小红色星云RNO 109，以及下方的赫比格-哈罗天体HH32。这些乌云可能看起来很可怕，但据估计它们距离我们大约600光年远。在这个距离上，这个视场的跨度大约是7光年。

Part of a dark expanse that splits the crowded plane of our Milky Way galaxy, the Aquila Rift arcs through planet Earth's skies near bright star Altair. In eerie silhouette against the Milky Way's faint starlight, its dusty molecular clouds likely contain raw material to form hundreds of thousands of stars and astronomers search the dark clouds for telltale signs of star birth. This telescopic close-up looks toward the region at a fragmented Aquila dark cloud complex identified as LDN 673, stretching across a field of view slightly wider than the full moon. In the scene, visible indications of energetic outflows associated with young stars include the small red tinted nebulosity RNO 109 above and right of center, and Herbig-Haro object HH32 below. These dark clouds might look scary, but they're estimated to be some 600 light-years away. At that distance, this field of view spans about 7 light-years.
