The Webb Space Telescope will need to be extraordinarily cold in order to see the infrared light from the farthest reaches of the universe. Webb’s enormous sunshield will protect the telescope’s instruments from the Sun’s energy.
“Behind the Webb” is a recurring video series from HubbleSite, home of the Hubble Space Telescope and the upcoming Webb Space Telescope. Join host Mary Estacion as she goes behind the scenes to watch the construction and testing of the parts that will make Webb the world’s most powerful infrared telescope.
