couple successor is the james webb space telescope one of the most complex scientific instruments ever made and costing about $10000000000.00 so far it's also one of the most expensive well hubble mostly operates in the visible light spectrum the james webb telescope will work almost entirely with infrared light. the max planck institute for astronomy and heidelberg is involved in developing the new telescope astrophysicist klaus yeager says there are good reasons for working in the infrared range. i'm all in stellar nurseries dust absorbs visible life with infrared you can stare right into the system with its longer wavelengths it passes through the clouds the other reason is that the universe is expanding so the light from distant galaxies undergoes a red shift with an infrared telescope you can observe these objects much more clearly. the telescope picks cameras and instruments have to be kept very cold if faint heat signals to be detected. and that requires a lot of extra equipment including a sun shield the size of a tennis course of course that won't fit into any spacecraft so en
