Did We Really Encountered a Signal From Extraterrestrial Intelligence?
The Mystery Behind WOW Signal.
It was the day of 15th August 1977 when the most precendent event of the century had occurred. Astronomer Jerry R Ehman discovered the anomaly later that night while reviewing the data.
The WOW Signal was a strongband radio signal received on August 15, 1977 by Ohio State University Big Ear Telescope then used to support Search for Extraterrestrial Intelligence (SETI). It is believed that the signal came from Saggitarius constellation.
The WOW Signal lasted for 72 seconds and was never observed later on. So what was it? Does it really came from some alien civilization?
The answers are still unknown. From years American space agency NASA and scientists from all over the world have contributed in search for the origin of the signal.
Physicists from Cornell University had found out that any advance alien civilization attempting to communicate via radio signal might do using frequency of 1420 Hz which is naturally emitted by hydrogen, because its the most common element in the universe and its likely to be familiar with advance civilization.
There have been many attempts in finding the true origin in the first place. Many hypothesis have been ruled out and many new have come. But still no one is sure that what we observed on the night of Aug 15, 1977.
There have been around eleven IRMs( Interstellar radio messages) sent to different parts of sky to hundreds and thousands of light years away. In hope to get an answer one day. But as of now the question stands tall till we didn’t get a reply
ARE WE ALONE IN THE UNIVERSE OR WHAT?
