哈勃太空望远镜拍摄的一张著名的照片显示，这些恒星形成柱是由寒冷的气体和尘埃组成的，这些气体和尘埃在M16（鹰状星云，被称为创世之柱）内部长达数光年。这张詹姆斯·韦伯太空望远镜NIRCam的图像扩展了哈勃对该区域的探索，在这个标志性的恒星摇篮里有了更详细和更深入的了解。在韦伯的近红外图像中，特别令人震惊的是，在出生云中，物质在引力坍缩形成恒星时发出的红色辐射。鹰状星云距离我们大约6500光年。较大的明亮发射星云本身很容易成为双筒望远镜或小型望远镜的目标。M16位于我们银河系的平面上，在天空中星云丰富的部分，朝向分裂的蛇尾星座（蛇的尾巴）。

A now famous picture from the Hubble Space Telescope featured these star forming columns of cold gas and dust light-years long inside M16, the Eagle Nebula, dubbed the Pillars of Creation. This James Webb Space Telescope NIRCam image expands Hubble's exploration of that region in greater detail and depth inside the iconic stellar nursery. Particularly stunning in Webb's near infrared view is the telltale reddish emission from knots of material undergoing gravitational collapse to form stars within the natal clouds. The Eagle Nebula is some 6,500 light-years distant. The larger bright emission nebula is itself an easy target for binoculars or small telescopes. M16 lies along the plane of our Milky Way galaxy in a nebula rich part of the sky, toward the split constellation Serpens Cauda (the tail of the snake).
