Description
WOW SIGNAL (detected August 15th 1977)
The Wow! signal was a strong narrowband radio signal detected by Dr. Jerry R. Ehman on August 15, 1977, while working on a SETI project at the Big Ear radio telescope of The Ohio State University then located at Ohio Wesleyan University's Perkins Observatory, Delaware, Ohio. The signal bore expected hallmarks of potential non-terrestrial and non-solar system origin. It lasted for the full 72-second duration that Big Ear observed it, but has not been detected again. The signal has been the subject of significant media attention.
Amazed at how closely the signal matched the expected signature of an interstellar signal in the antenna used, Ehman circled the signal on the computer printout and wrote the comment "Wow!" on its side. This comment became the name of the signal.
Location of the signal
Determining a precise location in the sky was complicated by the fact that the Big Ear telescope used two feed horns to search for signals, each pointing to a slightly different direction in the sky following Earth's rotation; the Wow! signal was detected in one of the horns but not in the other, although the data was processed in such a way that it is impossible to determine in which of the two horns the signal entered. There are, therefore, two possible right ascension values:
19h22m24.64s ± 5s (positive horn)
19h25m17.01s ± 5s (negative horn)
The declination was unambiguously determined to be −27°03′ ± 20′.
The preceding values are all expressed in terms of the B1950.0 equinox.
Converted into the J2000.0 equinox, the coordinates become
RA= 19h25m31s ± 10s or 19h28m22s ± 10s and declination= −26°57′ ± 20′
This region of the sky lies in the constellation Sagittarius, roughly 2.5 degrees south of the
fifth-magnitude star group Chi Sagittarii. Tau Sagittarii is the closest easily visible star.

Le Signal WOW (détecté le 15 Aout 1977)
Le signal « Wow! » fut un fort signal radio à bande étroite capté le 15 août 1977 par le radiotéléscope The Big Ear de l'université de l'État de l'Ohio. Présumé extraterrestre, ce signal a duré 72 secondes et n'a plus été détecté depuis.
C'est l'astrophysicien Jerry R. Ehman qui observa le phénomène alors qu'il travaillait avec le radiotélescope au projet SETI. Stupéfié de voir à quel point le signal correspondait à la signature attendue d'un signal interstellaire dans l'antenne utilisée, Ehman a entouré au stylo le passage correspondant sur la sortie imprimée et a écrit le commentaire « Wow! » (exclamation de surprise ou d'admiration en américain) dans la marge à côté. Ce commentaire est devenu le nom du signal.
Le signal était à bande étroite (quelques kHz) ;il venait d'une direction très précise du ciel, la durée de 72 secondes correspondant au passage d'un "lobe" de sensibilité de l'antenne sur ce point,lors du passage d'un second lobe quelques minutes plus tard, le signal avait disparu.
Cela suggère une origine dans l'espace, en orbite ou plus loin. Il n'y a pas d'explication physique connue. Une explication qui a été proposée pour le wow et pour d'autres signaux similaires trouvés depuis par SETI est qu'ils pourraient être des réflexions d'émetteurs radios terrestres sur des satellites, mais d'autres ont dit que ces réflexions ne pourraient pas renvoyer assez d'énergie. Restent des phénomènes physiques inconnus, ou des émissions de civilisations extraterrestres selon des modalités incomprises.

Very interesting!!
C'est sûr que nous ne sommes pas seuls dans l'univers, mais arriverons-nous à communiquer? très belle image, Magik!
wonderful image
Great image and work Magik.
Superbe travail, commentaire intéressant!
Fantastic!!!!
Yea I've heard about it..I Think it was ET Phoning Home..LOL
EXCELLENT IMAGE!
Cool! Superb looking!!
Wow ! ;)
I've watched shows about this fascinating signal! Great scene!
When I saw your title the first thing that came to mind was the famous incident. A most fascinating episode - very strange that it has never been detected again... And cool fractal too!
Interesting work and info! :)
MAGNÍFICA OBRA MEU AMIGO BELA CRIAÇÃO,OBRIGADO PELA INFORMAÇÃO.+++++++++5
Fantastic photo and work , Magik !Interesting info !
Fantastic work.
I remember the Wow... seems like sooo long ago...and maybe it was... it may have taken millenia to get here... a last signal from a race now long gone? cool artwork, very cool!
