The James Webb telescope is designed to detect light in the infrared portion of the spectrum, and its instruments will only work at a temp. of just a few degrees above absolute zero! But how do you test them??

The room will keep getting colder and colder. NASA has a live webcam of the room online with a look at the indoor and outdoor temperatures at the Manned Spacecraft Center in Houston!
This is literally just too cool 😉
