The james webb space telescope is designed primarily to observe

The James Webb Space Telescope is designed primarily to observe the infrared light from dim and very distant objects. Heat from huge distance can only be detected of telescope has to be kept very cold. That's why James Webb Space Telescope is kept very cold. In order to protect the telescope from external sources of heat and light, like the Sun, Moon, and Earth itself, as well as from heat emitted by the observatory itself, James Webb Space Telescope has a 5-layer, tennis court-sized sun-shield that acts like a parasol providing shade.

The correct answer is: infrared light.
