Astronomy Picture of the Day——带注释的银河中心

The Annotated Galactic Center

Explanation: The center of our Milky Way galaxy can be found some 26,000 light-years away toward the constellation Sagittarius. Even on a dark night, you can't really see it though. Gaze in that direction, and your sight-line is quickly obscured by intervening interstellar dust. In fact, dark dust clouds, glowing nebulae, and crowded starfieds are packed along the fertile galactic plane and central regions of our galaxy. This annotated view, a mosaic of dark sky images, highlights some favorites, particularly for small telescope or binocular equipped skygazers. The cropped version puts the direction to the galactic center on the far right. It identifies well-known Messier objects like the Lagoon nebula (M8), the Trifid (M20), star cloud M24, and some of E.E. Barnard's dark markings on the sky. A full version extends the view to the right toward the constellation Scorpius, in all covering over 20 degrees across the center of the Milky Way.

带注释的银河中心 

朝向射手座的方向看，大约在26,000光年远的地方就是我们银河系的中心 。即使在漆黑的夜晚，也休想看到它。 朝那个方向看，星际尘埃会很快遮挡您的视线。实际上，沿着肥沃的银河平面和我们银河系的中心区域挤满了黑暗的尘埃云、发光的星云和拥挤的恒星。这个带注释的视图是黑暗天空的收藏夹，尤其是对对于小型望远镜或观景台的双筒望远镜。裁剪后的版本将方向指向最右边的银河中心。它可以识别出许多著名的梅西耶天体，例如泻湖星云（M8），三叉戟（M20）等等。完整版本将视图向右延伸至天蝎座，整个范围横跨银河系中心超过20度 。
