发光的星际气体山脊和黑暗的尘埃云栖息在动荡的泻湖星云的宇宙深处。这个明亮的恒星形成区也被称为M8，距离我们大约5000光年。它是在人马座向银河系中心的望远镜之旅中很受欢迎的一站。由电离氢原子与剥离电子重新结合的红色辐射所主导，这张深望远镜拍摄的泻湖中心地带的照片大约有40光年宽。画面中心附近明亮的沙漏形状是由一颗巨大的年轻恒星的高能辐射和极端恒星风电离和雕刻而成的。

Ridges of glowing interstellar gas and dark dust clouds inhabit the turbulent, cosmic depths of the Lagoon Nebula. Also known as M8, The bright star forming region is about 5,000 light-years distant. It makes for a popular stop on telescopic tours of the constellation Sagittarius toward the center of our Milky Way Galaxy. Dominated by the telltale red emission of ionized hydrogen atoms recombining with stripped electrons, this deep telescopic view of the Lagoon's central reaches is about 40 light-years across. The bright hourglass shape near the center of the frame is gas ionized and sculpted by energetic radiation and extreme stellar winds from a massive young star.
