从远处看，整个东西看起来像一只鹰。然而，仔细观察鹰状星云，就会发现明亮的区域实际上是一个通往更大的黑暗尘埃壳中心的窗口。透过这扇窗户，一个明亮的工作室出现在那里，一个完整的疏散星团正在形成。在这个空洞中，由黑色尘埃和冷分子气体组成的高柱和圆形球体仍然存在于恒星仍在形成的地方。已经可以看到几颗年轻明亮的蓝色恒星，它们的光和风正在燃烧，并将剩余的细丝和气体和尘埃壁推开。老鹰发射星云，标记为M16，距离我们约6500光年，跨度约20光年，用双筒望远镜可以看到蛇星座。这张照片涉及长时间和深度曝光，并结合了硫（黄色）、氢（红色）和氧（蓝色）三种特定的发射颜色。

From afar, the whole thing looks like an eagle. A closer look at the Eagle Nebula, however, shows the bright region is actually a window into the center of a larger dark shell of dust. Through this window, a brightly-lit workshop appears where a whole open cluster of stars is being formed. In this cavity, tall pillars and round globules of dark dust and cold molecular gas remain where stars are still forming. Already visible are several young bright blue stars whose light and winds are burning away and pushing back the remaining filaments and walls of gas and dust. The Eagle emission nebula, tagged M16, lies about 6500 light years away, spans about 20 light-years, and is visible with binoculars toward the constellation of the Serpent (Serpens). This picture involved long and deep exposures and combined three specific emitted colors emitted by sulfur (colored as yellow), hydrogen (red), and oxygen (blue).
