Explanation: 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.

说明: 明亮的星际云气脊和黝黑的尘埃云，交织在礁湖星云狂乱的内部深处。这个又称为M8的明亮恒星形成区，离我们约有5,000光年远。纵然如此，当以望远镜巡礼银河系中心的人马座时，它仍然是一个很热门的标的。在这幅呈现宽约40光年礁湖星云中心区的望远镜深空影像里，最主要的色泽为电离氢原子和逸失的电子复合时，所发出的特征性泛红辉光。在影像中心附近的明亮沙漏状结构，则是受到一颗大质量年轻恒星的高能辐射电离及强烈恒星风雕塑的云气。
