The Webb Telescope is coming together, piece by piece, as teams around the country work to build this state-of-the-art observatory. Join our host, Mary Estacion, of the Space Telescope Science Institute, as she takes you behind the scenes to watch the construction and testing, and hear from the people who make it work.
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.
