Cooling the Cosmos
The key to the JWST's extraordinary capabilities lies in its ability to operate at extremely low temperatures, requiring onboard cooling systems to enhance its infrared sensitivity. Positioned at Lagrange Point 2, the telescope is shielded from the sun's overwhelming heat, allowing it to potentially detect the faintest signals from the universe, including the first light of the Big Bang. The meticulous calibration of its instruments is crucial for its mission to explore the cosmos.In this clip
