When we are outside it is crucial not to turn on lights, so as not to interfere with observations. This is why we only use red lanterns outdoors. Did you notice? These are the twin Magellan telescopes, launched in 2000 and 2002, and named Walter Baade and Landon Clay. If you notice, between the domes, there is a large room, which is there so that every two years the mirrors of the telescope can be repaired and restored. They are giant and crucial to the telescopes’ operations. I know that you want to see them too, shall we?
