For those of you who may not be familiar, the Arecibo Observatory was one-of-a-kind. It was an engineering feat as it sat over a giant sinkhole. An architectural marvel, it was visited by the likes of James Bond. One way this device was used for picking up objects potentially on a collision path with Earth and we may dearly miss that capability. There are no plans and rebuilding this once incredible structure however there is much more to the story with videos and you can find them HERE.
