On the night of August 15, 1977, in a quiet Ohio cornfield, a strange anomaly appeared on the printouts of Ohio State University’s Big Ear radio telescope. The sequence of characters—“6EQUJ5”—looked like nothing else in years of monotonous data. Astronomer Jerry Ehman circled it in red pen and wrote a single word in the margin: “Wow!” That brief annotation became the most famous note in the history of the search for extraterrestrial intelligence (SETI). The Wow! Signal has never been explained. It has never repeated. It has never been forgotten.

The Wow! Signal: One Night, One Signal, Endless Questions tells the story of this anomaly as if it were a cold case, a true crime investigation with no body, no suspect, and no resolution. Using meticulous research and narrative drive, it reconstructs the night of August 15, 1977, the telescope that captured the anomaly, the astronomers who struggled to interpret it, and the decades of silence that followed.

Why did the signal appear exactly at the hydrogen line—the frequency SETI theorists long believed most likely for interstellar communication? Why did it last the exact 72 seconds expected of a fixed celestial source passing through Big Ear’s beam? Why was it never heard again, despite countless follow-up attempts by telescopes around the world? Was it a deliberate broadcast from beyond Earth, a one-time cosmic postcard, or simply an unexplained artifact of human technology?

This book follows the trail across five decades of debate. It examines the initial suspicions—terrestrial interference, malfunction, satellites, comets—and why none fully matched the data. It explores the lives of those who discovered and defended the signal: Jerry Ehman, cautious to the end, and John Kraus, the stubborn dreamer who built Big Ear. It traces how NASA flirted with SETI only to abandon it under political ridicule, and how amateur detectives, UFO enthusiasts, and internet communities adopted the Wow! Signal as proof of alien contact. It shows how modern SETI, armed with billion-dollar technology, still lives in the shadow of that one anomaly.

Written in a gripping, investigative style, this is not science fiction—it is a true story of evidence, doubt, obsession, and mystery. The Wow! Signal remains the most tantalizing unsolved anomaly in astronomy. Whether it was alien or earthly, intentional or accidental, its legacy is permanent: one signal, one annotation, endless questions.

Readers fascinated by true crime, unsolved mysteries, astrophysics, or the search for extraterrestrial intelligence will find in these pages a case file like no other: rigorously factual, endlessly debated, and haunting in its refusal to be resolved.

The Wow! (pause) Signal

I’ve always been intrigued by the Wow signal and the information presented in this book does a good job covering the history of the signal, the instrument used to detect it, and all the interest surrounding it. Would have given a higher rating, however there is a downside.

Downside: although this isn’t the worst AI read book I’ve listened to, I’m still not a fan. Sometimes it learns to pronounce the words correctly, but still sounds ridiculous when it messes up. This is a science based book and AI should be able to pronounce words such as NASA, Arecibo, and 6EQUJ5. Also, having to hear “the Wow! (pause) signal” each time is exhausting.

Recommendation to authors, READ YOUR OWN BOOK. Humans doing human actions is still a worthy thing. AI sounds so lifeless and dull.
