They work just like optical telescopes. In fact, they ARE optical telescopes. Many ordinary reflecting telescopes are sometimes used for infrared observations. All that is needed is a camera capable of recording infrared light attached to the telescope. The telescope must be all reflecting, because any glass that the light passes through will absorb the infrared light. Also, the telescope must be above as much of the atmosphere as possible, because some gasses in the atmosphere absorb infrared light, especially water vapor and, to a lesser extent, carbon dioxide. Antarctica is good because the air is very dry there. High mountain tops are good for the same reason. Space is even better.

Virtually all new ground-based telescopes can see in the near-infrared. Works just like the optical component. They are located all over the world.

Far infrared wavelengths can only be seen from space. The only instrument I'm aware of which does this is the Spitzer Space Telescope.

Ditto, my 10 year old granddaughter knows this.
