Our scientific research on the #WowSignal also revealed many previously unknown historical facts, which inspired me to write a book about them. 🙂 #AreciboWow phl.upr.edu/wow/story

This notebook contains the original annotated computer code that helped the Big Ear telescope detect the famous Wow! Signal, and other signals, during the 1970s. #seti #retrocomputing #astronomyhistor

Our #AreciboWow project began as a search for Wow-like signals. It led us to an astrophysical explanation, new properties, and even a trip to the signal’s source, where we just made a surprising discovery. 😉 phl.upr.edu/wow/trip

I visited Bob Dixon, who served as director of the Big Ear radio telescope from 1973 to 1998. He was the driving force behind the Big Ear's SETI project that captured the legendary Wow! Signal. #AreciboWow #SETI #Astronomy #Astrophysics #WowSignal

If Wow! signals occur as rarely as galactic supernovas, roughly once every 50 years, then statistically, the next signal should be coming soon. 🤔 #AreciboWow

What’s next? We’ll keep studying decades of unpublished data from the 1960s to the 1990s, which may reveal new properties of the Wow! Signal or uncover other transient events. (9/n) #WowSignal #Astrophysics #SETI

Our revised Wow! Signal properties still fit the hypothesis of a sudden hydrogen cloud brightening from a maser flare or superradiance. We now have more clues to locate the source, if so. (8/n) #WowSignal #Astrophysics #SETI

So why an update to the Wow! Signal after so many decades? We had the chance to analyze long-forgotten, unpublished data using today’s technology — an astro-detective effort at its finest. (7/n) #WowSignal #Astrophysics #SETI

We found signals similar to the Wow! Signal, but demonstrated they were simply hydrogen clouds. The Wow! Signal, however, was much brighter and lasted only a short time, suggesting it was an entirely different phenomenon. (6/n) #WowSignal #Astrophysics #SETI

We also investigated every possible source of external or internal electronic radio interference and found none. We concluded it was a genuine signal originating far out in space. (5/n) #WowSignal #Astrophysics #SETI

Third, its frequency was higher — an odd result, as it implies a high velocity toward us, though such motions are not unusual for stars and gas within our galaxy. (4/n) #AreciboWow #WowSignal #Astrophysics #SETI

Second, we found the signal was much stronger than previously believed. Our estimate of 256 Jy (at 30 SNR) is a very conservative lower bound, and the source is more likely to be within our galaxy. (3/n) #AreciboWow #WowSignal #Astrophysics #SETI
