Question 3 • EF English 12 - 1st 9 Weeks (New)
Webb’s five-layer sunshield keeps the telescope’s instruments cold by blocking sunlight and directing heat away from the telescope’s cold side. It does not store heat or use sunlight to generate power; some heat is absorbed by the layers and radiated away into space. Therefore, the main purpose is to block and redirect heat away from the telescope’s cold side.
