Radio, The Astronomical Ear, and the Wow! Signal

Since the early days of radio and tv we be pleased been freely broadcasting indicators into place. For some time now, we be pleased been listening too. A gargantuan radio telescope at Ohio Divulge College identified as affectionately The Astronomical Ear was one of many foremost listeners. The Astronomical Ear was about the scale of three soccer fields and consisted of an tall metal floor airplane with two fence-fancy reflectors, one mounted and one tiltable. It relied on the Earth’s rotation to help scan the sky. This photo, taken by stale Astronomical Ear student volunteer Rick Scott, appears to be like out across the floor airplane toward the mounted reflector with the radio frequency receiver horns within the foreground. Starting in 1965, the Astronomical Ear was feeble in an ambitious gaze of the radio sky. Within the 1970s, it turned the foremost telescope to continually hear for indicators from extraterrestrial civilizations. For an exhilarating moment within the course of August 1977 a really solid, sudden signal, dubbed the Wow! Signal, was detected by the Astronomical Ear. Nonetheless alas, heard finest once, the source of the signal might presumably per chance now not be obvious. In May per chance presumably 1998 the closing items of the Astronomical Ear had been torn down. Consultants Debate: How will humanity first gaze extraterrestrial existence?
