The 305m diameter radio dish of the Arecibo Observatory in Puerto Rico. There are massive telescopes, after which there are the really humongous telescopes, like a few of the radio telescopes. These bad boys are so huge that the most important of them takes up a whole valley. That is the effectively-identified Arecibo Observatory in Puerto Rico, that lots of people doubtless know from Golden Eye, X-files or Contact, to call a number of times it has been utilized in widespread culture. The observatories are, of course, mainly used to do astronomical observations, and never as fancy movie sets. The planetary radar transmitter right here, and on the Goldstone Deep Space Network site in California are used extensively to observe asteroids, the terrestrial planets, and the larger satellites of Jupiter and Saturn. To do that, they run a whole bunch of kilowatts of UHF signal out by every telescope. By the point the beam is distributed across the many 1000's of square meters of the first telescope reflector, it’s diluted to the purpose that it doesn’t pose a hazard to anything.
