The James Webb Space telescope reaches its final destination on Jan. 24, 2022 at Lagrange Point 2 or L2 on the other side of the moon, one million miles from earth. In an amazing feat of science one side of the telescope the instrument side will be cloaked in frigid darkness, and the other will defect temperatures of 230 degrees centigrade facing the sun. This keeps the telescope's sensors cool so that stray heat does not interfere with its infrared scans of ancient galaxies and planets orbiting other stars.
