In 1963, Ohio State University began the Search for Extraterrestrial Intelligence (SETI) project. As part of this project they developed The Big Ear radio telescope. On August 15, 1977 The Big Ear telescope recorded a strange narrow band radio burst. The signal was indicative of technological advancement as it stood out distinctly from the background noise of signals from space. Many people have speculated that the signal was sent by an advanced civilization.
