7 $\begingroup$ The Webb telescope is an infrared telescope, therefore heat from sun can cause noise and even damage its super sensitive sensors (If I'm wrong please correct me, I'm not expert). So the telescope should be kept away from sun light. But I have heard that creating sunshield for Web telescope was an engineering challenge. I can not understand the technical difficulties of creating a sunshield which blocks sunlight to reach the telescope. Can someone explain it to me? space-telescopejames-webb-space-telescopeinfrared Share Improve this question Follow edited yesterday Peter Erwin 18.5k11 gold badge4444 silver badges6060 bronze badges asked yesterday Amir reza RiahiAmir reza Riahi 18155 bronze badges New contributor Amir reza Riahi is a new contributor to this site.
