Caption: A composite image of the Eagle Nebula (M16) with NASA's Chandra X-ray Observatory and the Hubble Space Telescope penetrates the dark columns of gas and dust to reveal how much star formation is happening there. The Chandra data (red, green, and blue represent low, medium, and high-energy X-rays respectively) show very few X-ray sources in the so-called "Pillars of Creation" themselves. This indicates that star formation peaked in this region several million years ago.

Scale: Image is 2.5 arcmin across.
