On Wednesday, NASA announced that it was ready to start taking test images and aligning the optics of the JWST after the telescope’s instrumentation reached its final operating temperature of minus 448 degrees Fahrenheit (or minus 267 degrees Celsius) partway through last week.Cool news! Webb’s MIRI instrument recently passed through its critical “pinch point” and cooled to just a few kelvins above absolute zero, which is the coldest you can go: https://t.co/jjE7xTal0OWondering why MIRI is extremely chill?
