👉 The extraordinary engineering behind the James Webb Space Telescope (JWST) lies in its innovative design and construction, enabling it to capture unprecedented images of the universe. Its massive 6.5-meter primary mirror, composed of 18 hexagonal segments made from beryllium for lightweight strength and thermal stability, can be precisely adjusted to form a perfect mirror. The telescope's sunshield, a five-layered structure measuring 22 meters across, is designed to block light from the sun, Earth, and JWST itself, maintaining the instrument's extremely cold operating temperature of around -223°C. This engineering marvel also includes advanced infrared detectors and a complex system of actuators to fine-tune the mirror's shape, allowing JWST to observe distant galaxies, star-forming regions, and potentially even exoplanet atmospheres with unparalleled clarity and sensitivity.
