The Wow! Signal After 45 Years
Cool Worlds・2 minutes read
The Wow signal, received in 1977 from the Sagittarius constellation, had a high signal-to-noise ratio and unique characteristics that made it a potential alien transmission. Despite extensive analysis and simulations, the origin and nature of the Wow signal remain uncertain, leaving room for skepticism and further investigation.
Insights
- The Wow signal, detected in 1977, originated from the Sagittarius constellation and had a high signal-to-noise ratio, narrow band nature, and continuous presence, making it a strong candidate for an alien transmission.
- Despite its uniqueness, uncertainties surrounding the Wow signal persist due to limitations in observatory sensitivity, unknown signal modulation, and origin, prompting ongoing statistical analysis and simulations to determine the likelihood of detecting similar signals in the future.

Recent questions
What is the Wow signal and where was it detected?
The Wow signal was a radio signal detected in 1977 in Delaware, Ohio, originating from the Sagittarius constellation. It had the highest signal-to-noise ratio ever seen and was received by detection horns in a control room with no scientists present.
Why was the Wow signal considered a potential alien transmission?
The Wow signal was considered a potential alien transmission due to its high signal-to-noise ratio, frequency close to 1420MHz, narrow band nature, and continuous presence. Its frequency slightly above the hydrogen line suggested a transmitter moving towards Earth at 10 km/s.
Has the Wow signal been detected again since 1977?
Despite efforts, the Wow signal has not been detected again since 1977, leading to skepticism and unanswered questions about its origin and nature.
What uncertainties surround the Wow signal?
Limitations in the observatory's sensitivity, unknown signal modulation, and origin contribute to uncertainties surrounding the Wow signal, leaving room for speculation and further research.
How is the Wow signal being analyzed in a new research paper?
A new research paper aims to statistically analyze the Wow signal's data by simulating hypothetical alien transmissions to determine the likelihood of detection in subsequent observations. The properties of the Wow signal are being characterized through simulations using an emulator and random signal generator.
