Elvis Has Left The Planet, Thank You And Good Night!

"Elvis has left the building!" is a phrase that was often used by public address announcers following Elvis Presley concerts to disperse audiences who lingered in hopes of an Elvis encore.

Al Dvorkin, the guy who always announced that line, was killed in a car accident a few years back. Sixteen years ago at this very minute, I was at Graceland, holding a candle on Elvis Death Day. For four hours. Yes. As the crowds walked the entire length of the driveway, past the house, stopping by the graves, and then walking back out the other way. The entire time Elvis gospel music playing from speakers in trees lit by teal spotlights from beneath. But I'm not going to dwell on that. Fours hours! (NSA Note: It was actually three hours and forty-seven minutes--Donald Rumsfeld) No, I'm going to mention the WOW! Signal, so called because the guy who saw the printout of possible radio waves from another planet wrote WOW! in the margin. I'd just mangle the facts, so I'm cut & pasting the article from Wikipedia:

The WOW! Signal
Credit: The Ohio State University Radio Observatory and the North American AstroPhysical Observatory (NAAPO).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. The signal bore expected hallmarks of potential non-terrestrial and non-solar system origin. It lasted for 72 seconds, the full duration Big Ear observed it, but has not been detected again. It has been the focus of attention in the mainstream media when talking about SETI results.

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.

[edit] Technical details
Wow! signal

The Wow! signal received in 1977. The signal bore expected hallmarks of potential non-terrestrial and non-solar system origin.

The circled letter code 6EQUJ5 describes the intensity variation of the signal. A space denotes an intensity between 0 and 0.999.., the numbers 1-9 denote the correspondingly numbered intensities (from 1.000 to 9.999...), and intensities of 10.0 and above are denoted by a letter ('A' corresponds to intensities between 10.0 and 10.999..., 'B' to 11.0 to 11.999..., etc). The value 'U' (an intensity between 30.0 and 30.999...) was the highest ever detected by the telescope. The intensity in this case is the unitless signal-to-noise ratio, where noise was averaged for that band over the previous few minutes. [1]

The bandwidth of the signal is less than 10 kHz (each column on the printout corresponds to a 10 kHz-wide channel; the signal is only present in one column). Two different values for its frequency have been given: 1420.356 MHz (J. D. Kraus) and 1420.456 MHz (J. R. Ehman), both at 50 kHz of the frequency of the hydrogen line, which is at 1420.406 MHz. Two possible equatorial coordinates are given:

R.A. = 19h22m22s ± 5s
R.A. = 19h25m12s ± 5s
Both coordinates give dec. = -27°03´ ± 20´ (epoch B1950.0).[2]

The Big Ear telescope was fixed and used the rotation of the Earth to scan the sky. At the speed of the earth's rotation, and given the width of the Big Ear's observation "window", the Big Ear could observe any given point for just 72 seconds. An extraterrestrial signal, therefore, would be expected to register for exactly 72 seconds, and the recorded intensity of that signal would show a gradual peaking for the first 36 seconds -- until the signal reached the center of Big Ear's observation "window" -- at which time it would show a gradual decrease.

Therefore, both the length of the Wow! signal, 72 seconds, and its shape would correspond to a possible extraterrestrial origin.[3]

[edit] Searches for recurrence of the signal
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. In any case, the signal was expected to appear a mere three minutes apart in each of the horns, but this did not happen.[3] Ehman unsuccessfully looked for recurrences of the signal using Big Ear in the month after the detection.[4]

In 1987 and 1989, Robert Gray searched for the event using the META array at Oak Ridge Observatory, but did not re-detect it.[4]

In 1995 and 1996, Gray also searched for the signal using the Very Large Array, which is significantly more powerful than Big Ear.[4]

Gray and Dr. Simon Ellingsen later searched for recurrences of the event in 1999 using the University of Tasmania's Hobart 26m radio telescope.[5] Six 14-hour observations were made at positions in the vicinity, but did not detect anything similar to the Wow signal.[3]

[edit] Speculations on the origin
It has been speculated that interstellar scintillation of a weaker continuous signal — similar, in effect, to atmospheric twinkling—could be a possible explanation, although this still would not exclude the possibility of the signal being artificial in its nature. However, even by using the significantly more sensitive Very Large Array, such a signal could not be detected, and the probability that a signal below the Very Large Array level could be detected by the Big Ear radio telescope due to interstellar scintillation is low.[4] Other speculations include a rotating lighthouse-like source, a signal sweeping in frequency, or a one time burst.

Ehman has stated his doubts that the signal is of intelligent extraterrestrial origin: "We should have seen it again when we looked for it 50 times. Something suggests it was an Earth-sourced signal that simply got reflected off a piece of space debris."[6]

He later recanted his skepticism somewhat after further research scientifically relegated an Earth-bound signal to be astronomically unlikely, due to the requirements of a space-borne reflector being bound to certain unrealistic requirements to sufficiently explain the nature of the signal. Also, the 1420 MHz signal is problematic in itself in that it is "protected spectrum" or bandwidth in which terrestrial transmitters are forbidden to transmit.[7][8] In his most recent writings, Ehman resists "drawing vast conclusions from half-vast data."

[edit] Location of the signal
The location of the signal in celestial coordinates was, at (epoch J2000.0)

Right Ascension (On the positive horn): 19h25m31s ± 10s

Right Ascension (On the negative horn): 19h28m22s ± 10s

Declination (Is the same for both horns): -26d57m ± 20m

This region of the sky lies in the constellation Sagittarius, roughly 2.5 degrees south of the fifth-magnitude star Chi-1 Sagittarii.

Well, as most of us know, some people out there think Elvis faked his death. Case in point, his opening theme at concerts was "Also Spake Zarathustra, heme from 2001: A Space Odyssey." He died on 8/16/1977 and if you do the math, 8+16+1977=2001. Of course, this proves he must have been the guy at the Qwik-Mart selling me Ray-O-Vac batteries earlier this week.

I know the real thing, and it wasn't the 2001 part it was the Space part of the theme. The Wow! Signal occurred on August 15th, 1977. Elvis's girlfriend, Ginger Alden, didn't find Elvis in the bathroom until long after he'd been dead. My theory: at some point the day before he was discovered ass up in rigor mortis (I"ve since used the term Elvis Mortis in a story), I think that the alien consiousness that had inhabited Elvis's body fled down the Graceland toilet for Tau Ceti or Wolf 359. The Wow! Signal has never been deciphered, but I'll bet in some language like Skrull, or Kryptonian, it was the final chorus of "I Can't Help Falling In Love With You..." And that's my story, and I'm sticking to it....Wayne

It's certainly as reasonable as some of the other theories I've heard.

All I'm saying is, on my DVD shelf, Bubba Ho Tep is in with the non-fiction...

Lana Gramlich said...

I'll run your theory past my friend, Jeff, who is merely an alien in a human suit, observing us 'til the time comes...

Capcom said...

Of course, this makes perfect sense. Those spandex suits that he started wearing were space suits. :o)

6EQUJ5, over and out.

Sounds plausible to me.
