波浪形的明亮山脊和尘雾穿过这张近距离拍摄的恒星形成区域M8，也被称为泻湖星云。这张清晰的伪彩色照片是由8米双子南望远镜拍摄的窄带可见光和宽带近红外数据合成的，整个图像跨越了约20光年，穿过了星云中有时被称为南崖的区域。这张非常详细的图像探索了许多新生恒星嵌入明亮的边缘云和赫比格-哈罗天体的尖端之间的联系。赫比格-哈罗天体大量存在于恒星形成区域，是年轻恒星在形成过程中释放出的强大喷流加热周围的气体云和尘埃云而产生的。这个宇宙泻湖距离我们大约5000光年，位于人马座和银河系的中心。(关于位置和规模，请查看这张在泻湖星云中叠加南悬崖特写的图片。比例图由R. Barba提供。)

Undulating bright ridges and dusty clouds cross this close-up of the nearby star forming region M8, also known as the Lagoon Nebula. A sharp, false-color composite of narrow band visible and broad band near-infrared data from the 8-meter Gemini South Telescope, the entire view spans about 20 light-years through a region of the nebula sometimes called the Southern Cliff. The highly detailed image explores the association of many newborn stars imbedded in the tips of the bright-rimmed clouds and Herbig-Haro objects. Abundant in star-forming regions, Herbig-Haro objects are produced as powerful jets emitted by young stars in the process of formation heat the surrounding clouds of gas and dust. The cosmic Lagoon is found some 5,000 light-years away toward the constellation Sagittarius and the center of our Milky Way Galaxy.
