Strange Columbus The Wow Signal Columbus, Ohio

No, we’re not talking about being able to get HBO from the modern cable company. This signal had even worse consistency.
On August 15, 1977, the Big Ear telescope– officially known as the Ohio State University Radio Observatory- recorded a surprisingly strong signal of non-terrestrial origin. At the time, the telescope was being utilized to search for signs of extraterrestrial life, a task that many large installations around the world had been occasionally involved in, with very little to show for the effort.

The observatory, located of of US 23 between Columbus and Delaware, had been working with SETI (Search for Extraterrestrial Intelligence) since 1973, after the installation had been deemed “defunct”. Equipment listening for frequencies would print out results on long sheets of paper, and while reviewing the data, the signal was first detected by astronomer Jerry Ehman at around 10:16PM. The readout featured the sequence 6EQEJ5, a combination that indicated frequency and signal intensity. The signal’s intensity was 30 standard deviations above normal background noise, and lasted for the full 72 seconds that the Big Ear was able to listen. Both the length and strength fell in line with expectations of what an alien signal would be like. Ehman was so shocked by it, that he circled the sequence and marked it with a “Wow!”, which is how the signal got its name.

The exact origin of the signal is even today unknown, but it was narrowed down to somewhere in the Sagittarius Constellation. Despite multiple attempts by the team at Big Ear, as well other other Earth-bound observatories to locate the signal again, they were unable to. This lack of repetition has meant that theories to its origin- either natural or otherwise- remain unconfirmed. Ehman himself was later skeptical of it actually coming from space and suggested it was signal from Earth that just happened to bounce off a satellite of some kind, but subsequent studies suggested this was highly unlikely.

For the next few decades, astronomers made multiple attempts to locate the signal again, but it was never heard again. To date, it remains one of the most mysterious space signals ever captured.

In 1997, the Big Ear ended all operations after 40 years of use. The following year, it was demolished to expand a golf course.



Before and After: Ohio State Campus Aerials

It’s hard to imagine Columbus without its flagship university. While today Ohio State is one of the nation’s largest universities and a powerful influence in and out of Columbus in many ways, it got its start as just a humble agricultural college in 1870. Let’s go back to a time and look at these Ohio State campus aerials from 1919, and compare them to the same views today.

This 1919 photo of the Oval and the surrounding neighborhood shows just how small the campus was back then. Residential areas began just to the north of of the Oval. Over the years, almost every single building in this photo would be demolished in OSU’s never-ending quest to expand and modernize.

The residential neighborhood is long gone, replaced with new student residences, offices and educational buildings. Almost nothing remains the same- even the street grid itself has been dramatically altered.

This photo of Campus further east show the famous castle-looking Armory, along with an athletic field and part of High Street.
After

Some buildings remain recognizable, but not many. The athletic field disappeared by the 1930s, and the Armory burned down in disastrous fire in the early 1950s. It iconic castle towers were recreated somewhat in the Wexner Center for the Arts, which occupies the former Armory location.

Clearly, Ohio State’s campus has changed drastically over the last century. No doubt a century from now, it will be equally as unrecognizable to us as the current iteration would be to students from long ago.
