Behind the Webb Episode 29 - Working Stiff.

The James Webb Space Telescope needs to be kept as cold as possible in order to detect infrared light from faint and very distant objects.

A key component of this is the observatory's tennis court-sized sunshield, which obstructs the warmth of the Sun. In this episode of "Behind the Webb," engineers add special structures to the sunshield that shape it to best reflect heat.
