Webb27 dec. 2024 · JWST is receiving sunlight because it is relatively near to the sun. At Neptune, the amount of sunlight is much less. As I understood, the heat shield is to shield the telescope from the heat of the sun. The telescope should cool down to just a few dozen kelvin in order to have low noise in the detector.

Webb8 juli 2013 · The shield - the silver structure visible in this photograph - will also help deflect any other stray thermal light. The other three instruments, that all operate in the near infrared wavelength region, and the ISIM - the black structure - will be cooled to 40K. WebbJWST is primarily a large scale, passive cryogenic design, and the cold side sensitivity to small amounts of heat is very high. If the attenuation of heat across the core region is worse than model predictions, the risk is that the observatory won’t reach the deep cryogenic temperatures required for operation. JWST takes advantage of the
