The temperature differences between the hot and cold sides of the James Webb Space Telescope five-layer sunshield. The sunshield acts as large parasol allowing the main mirror, optics, and instruments to passively cool to 40 kelvins (−233 °C; −388 °F) or cooler, [6] and is one of the enabling technologies that will allow the JWST to operate.
