The Signal – WOW! 1977 Extraterrestrial Radio Transmission Field Analysis Vintage Graphic T-Shirt

Big Ear Radio Observatory, Ohio State University. August 15, 1977. 22:16 EST. Signal duration: 72 seconds. Origin: Chi Sagittarii. Classification: UNEXPLAINED.

Dr Jerry Ehman circled it on the printout and wrote one word beside it: Wow! A 72-second narrowband radio signal, originating from deep space, bearing every hallmark of extraterrestrial intelligence — and never repeated, never explained, never officially acknowledged as anything other than anomalous. This gripping graphic tee renders the WOW! signal's original radio telescope data printout in authentic 1940s technical illustration style — the Big Ear telescope annotated, the signal wave charted, and Ehman's famous handwritten notation immortalised in period military typeface.

6EQUJ5. The most important sequence of characters ever recorded. Still waiting for the reply.
