Artist's illustration of the James Webb Space Telescope's primary mirror, made of 18 hexagonal segments, interlocking like honeycomb to form a larger hexagon, with one open space in the center. Text to the left of the mirror reads “Cosmic Dawn: The Untold Story of the James Webb Space Telescope.” The iconic Carina Nebula Webb image is superimposed on the mirror. The image is divided horizontally by an undulating line between a cloudscape forming a nebula along the bottom portion and a comparatively clear upper portion. The upper portion of the image is blueish, and has wispy translucent cloud-like streaks rising from the nebula below. The orangish cloudy formation in the bottom half varies in density and ranges from translucent to opaque, with ridges, peaks, and valleys, similar to a mountain range.
