Mystery Behind-Wow! Signal

By

On August 15, 1977, the Ohio State University's received a strong radio signal which was used to search for extraterrestrial intelligence.

When Astronomer Jerry R. Ehman was reviewing this recorded signal, he was so delighted that he circled the computer printout, and wrote a comment stated as Wow!




Analysis of the signal showed that it displayed all the hallmarks of coming from interstellar space. The entire signal sequence lasted for the full 72-seconds which is unusual for a comet. Many hypothesis on the existence of this signal has advanced which makes the Wow! Signal the strongest candidate for an alien radio transmission ever detected.

Conclusion:-

Jerry R. Ehman didn’t find aliens but he did find two suspicious looking comets. This could be significant because comets are surrounded by clouds of hydrogen gas that are millions of kilometres in diameter. The ‘Wow!’ signal itself was detected by Ehman at 1420MHz, which is a radio frequency that hydrogen naturally emits.

If it isn’t comets, SETI scientists still have their best candidate for an extraterrestrial signal.
