The IR solution! (1 jan 2000 ano – 1 jan 2020 ano)

Descrição:

Since anything warm radiates infrared energy,the detector must be isolated in very cold surroundings; often, it is held near absolute zero (1 to 3 K) by immersing it in liquid helium. The second step is to reduce the radiation emitted by the telescope structure and optics, and to block this heat from reaching the infrared detector.
