ALT Illustration of the James Webb Space Telescope at the right with its gold, hexagon-shaped primary mirror and multi-layer sunshield. At left is a representation of its 18 primary mirror segments, which takes up about two-thirds of the view. Each segment is outlined in yellow and contains a different Webb image, artist’s concept, or spectrum (graph). The images display dying stars puffing off layers of gas and dust, spiral galaxies, planets, and deep fields of space spattered with fuzzy white galaxies. Three yellow, orange, and red wavy lines appear atop everything else, running left to right. The backdrop shows filaments of red gas and dust, white and blue stars, and distant galaxies, all against the black background of space.
