Ensconced in the foothills of Stanford, CA, the radio telescope known simply as The Dish is a landmark visited by around 1,500 people every day. Yet, while undoubtedly a popular site for hikers and joggers, The Dish is also actually still operational today, used by both academics and other researchers. Built by the Stanford Research Institute in 1966, this 150-foot-diameter (46m) behemoth was initially intended for study into the chemical make-up of our atmosphere but, with its powerful radar antenna, was later used for communication with satellites and spacecraft — notably the Voyager probes sent forth to explore the outer solar system.
