BREAKING ASTRONOMY NEWS! After 49 years, the mystery of exactly where the Wow! Signal came from has been solved. The #AreciboWow "has solved this mystery using three independent methods." But looks like we'll have to wait a little longer for the answer, as they're planning to present their findings next year. I can hardly wait! Here's some background 👇 The Wow! Signal was a strong, narrowband radio signal detected on August 15, 1977, by Ohio State University’s Big Ear radio telescope during a SETI (Search for Extraterrestrial Intelligence) survey.​ It appeared near the 1420 MHz hydrogen line (a frequency long considered a natural “calling card” for any technological civilization) and lasted the full 72 seconds of the telescope’s observing window as Earth rotated. A few days later, volunteer astronomer Jerry Ehman reviewed the computer printout, circled the intensity sequence “6EQUJ5,” and wrote “Wow!” in the margin, giving the signal its name.​ Despite many follow up searches, it was never detected again. Its one time nature and lack of modulation or encoded message leave its origin open: possible natural explanations (such as a briefly energized hydrogen cloud, potentially triggered by a magnetar or similar transient) have been proposed in recent analyses, but none are confirmed, and the signal remains one of the most famous unexplained events in SETI history.
