It’s almost 4 months after it was launched into space James Webb Telescope NASA Approximately operational. like nasa Communications, the telescope’s “coldest” instrument has recently reached its operating temperature. NASA gives them minus 266 degrees Feather.

The low temperature is necessary because all 4 of Webb’s instruments detect infrared light. should be cooled infrared emission be suppressed. However, lower temperatures are also necessary dark current Occurs when the atoms in the telescope’s detectors vibrate.

Recently, MIRI – an instrument intended to be used for observations in the mid-infrared light spectrum – was cooled accordingly. According to the US space agency, this effort was not an easy one and required the deployment of a cryocoolers,

The telescope will now take more test images of celestial objects to calibrate the instruments. If everything goes according to plan, the telescope will be June or July Start your regular operation.
