June 2023 - The Universe of Very Cold: The James Webb Space Telescope, MIRI, and the Cryocooler
Time: 7 p.m. PDT (10 p.m. EDT; 0300 UTC)
The James Webb Space Telescope (JWST) takes incredible images using infrared light. The optics and science instruments must be incredibly cold, especially JWST’s Mid-Infrared Instrument (MIRI), which needs to be at a temperature of less than 7 kelvins, or -447 F. This is not possible without the Cryocooler, which keeps MIRI’s detectors cool.
