All Things Space, UFOs, etc.The Wow! Signal: New analysis closes in on mysterious source Posted on September 2, 2025 by Administrator Do you remember the Wow! Signal? It was a strong radio signal from deep space that the early SETI (Search for Extraterrestrial Intelligence) project at Ohio State University detected back on August 15, 1977. The enigmatic signal seemed like it might have been artificial in nature. But unfortunately, it was only detected once. Now, researchers from the Arecibo Wow! project at the University of Puerto Rico at Arecibo have re-analyzed this fleeting blip from the cosmos.
