"Radiative cooling is one of the few ways an object in space can give off energy. In particular, white dwarf stars are no longer generating energy by fusion or gravitational contraction, and have no solar wind. So the only way their temperature changes is by radiative cooling. See more In the study of heat transfer, radiative cooling is the process by which a body loses heat by thermal radiation. As Planck's law describes, every physical body spontaneously and continuously emits electromagnetic radiation See more Mechanism Infrared radiation can pass through dry, clear air in the wavelength range of 8–13 µm. Materials that can absorb energy and radiate it in those wavelengths exhibit a strong cooling effect. Materials that can also reflect 95% or … See more Climate change The widespread application of passive daytime radiative cooling (PDRC) technologies that use the infrared window (8–13 µm) to … See more • Heat shield • Optical solar reflector, used for thermal control of spacecraft • Passive cooling • Radiative forcing • Stefan–Boltzmann law See more " - How does radiation cooling occur
