![]() To this day, the Wow! signal remains unexplained and unrepeated. Kraus and others have even searched for stars that could be the source of the signal: “We checked star catalogs for any sun-like stars in the area and found none,” wrote Kraus. Nor has anything like it been observed in any other part of the sky. The Big Ear team continued to observe the same part of the sky, as have others, but the Wow! signal never returned. The director of the observatory, John Kraus, later gave a detailed account of the observation: “The WoW” signal is highly suggestive of extraterrestrial intelligent origin, but little more can be said until it returns for further study,” he wrote, in a letter to the astronomer Carl Sagan. Nevertheless, the signal was so powerful and unusual that Jerry Ehman, the astronomer who analyzed the data print out, annotated the signal with the word “Wow!”. The team quickly ruled out a terrestrial origin or a broadcast from a satellite. 15, 1977, it found one - a strong, intermittent signal lasting for 72 seconds, that stood out from the background noise like a searchlight. Throughout the 1970s, Big Ear searched for signals from extraterrestrial civilizations. But Big Ear nevertheless made one of the most famous observations in the history of astronomy, one that till this day has never been explained. Big Ear was never the world’s biggest radio telescope, nor its most sensitive. And maybe, just maybe, one day, we’ll be ready to finally make contact.When the Big Ear Radio Telescope in Delaware, Ohio, was disassembled in 1998 having operated for over 30 years, it was replaced by a golf course. And the WOW! Signal is a constant reminder that sometimes, guests may pop in when you least expect it. Such is the case for the Blue Marble Space Institute of Science and the SETI Institute. The new area of study within the SETI research community includes searching for technosignatures. And while this historical moment over forty years ago remains a mystery, it hasn’t stopped SETI researchers from continuing their pursuits. While the explanation brought forward by Paris and his team is compelling, the team admits that they can’t say with certainty that this explains to Wow! Signal. Outlook: The Wow! Signal Drives Curiosity (and maybe that is all that matters). When Popular Mechanics published an article concerning his team’s theory, astronomers from Ohio State University pointed out that comets could not have accounted for the signal. However, even Paris’ theory doesn’t seem to be accepted by everyone. Pair of Supermassive Black Holes Closest to Earth They also tested readings by three different comets and found results in the data very similar to the Wow! Signal. They elaborated on their theory by proving that two different comets had been in the exact area that the Big Ear telescope had been monitoring that night. He and his team argued that the movement of a comet would explain why the signal was never heard again. Petersburg College in Florida, published a paper in the Journal of the Washington Academy of Sciences that proposed that the signal may have come from a hydrogen cloud accompanying a comet. More recently, astronomer Antonio Paris, out of St. Other theories posit a possible supernova and even a glitch in the university’s computer system. However, since no other telescopes picked up the signal that night, those two theories seem to wash out. Initial explanations included a stray signal from an unknown military satellite and possibly even a signal that may have bounced off the Moon. There have been many theories put forward to explain the Wow! Signal. The signal intensity of 10 to 11 was represented by the letter A, and 11 to 12 was represented by a B, and so on. 0s and 1s were simply silent delays in computer processing, while numbers ranging from 1 to 9 indicated a range of low to mid-intensity cosmic signals. The university’s computer system to measure the intensity of signals from space used a simple alpha-numeric code. The data that came back from the signal stood out amongst the low numbers of background noise. One of the team members, Jerry Ehman, recorded a 72-second signal that, at the time, was pointed at a group of stars called Chi Saggittarii in the Sagittarius constellation. In August of 1977, a team of astronomers at Ohio State Observatory detected something unusual while using “The Big Ear,” the appropriately named radio telescope at Ohio State University. But in 1977, a lone radio astronomer in Ohio detected a signal that was so out of the ordinary that he couldn’t help but scribble one word next to the data he’d received “Wow!” Background: What is the “Wow!” Signal? The search for extraterrestrial life using radio signals has been an uphill battle for decades, yielding very few results.
