WOW Signal: Was It Aliens Or Just a Comet?

WOW Signal: Was It Aliens Or Just a Comet?

     There’s no such thing as a “close call” in SETI – either the radio telescope has picked up an alien signal, or it hasn’t. “Close” doesn’t exist in this one-bit experiment, any more than it does in pregnancy.

… At close to midnight on August 15, 1977, the massive radio telescope of the Ohio State University, known to its friends as the Big Ear, recorded a signal so impressive to the astronomer examining the instrument’s logs, he wrote “Wow!” on the computer printout.

It had all the characteristics one would anticipate from a signal produced by a deep space transmitter. This agreement with hopeful expectation, coupled with the undoubted appeal of the signal’s beguiling moniker, led to many efforts to find the WOW signal a second time. These attempts were made on such radio telescopes as the Very Large Array in New Mexico and, of course, the Big Ear itself. However, the result was always the same: radio silence.

[…]

But a paper published more than a year ago by Antonio Paris and Evan Davies makes a different claim: a natural solution to the puzzle of the WOW signal. It wasn’t earthly interference, problems with the equipment, or even ET; it was natural radio emission from hydrogen gas streaming off a nearby comet. …

The comet hypothesis, in my opinion, doesn’t work….

Alien Argument for ‘WOW’ Signal Continues …

Alien Argument for 'WOW' Signal Continues ...

     An astronomer thinks he’s pinpointed the source of a mysterious radio signal from space: a passing comet that nobody knew about. But his colleagues said they’re still skeptical of the explanation, noting that comets don’t emit radio waves in the right way.

Yet several astronomers, including Ehman, think Paris is wrong about the comet….

“We should have seen the source come through twice in about 3 minutes: one response lasting 72 seconds and a second response for 72 seconds following within about a minute and a half,” Ehman told Live Science. “We didn’t see the second one.”

The only way that can happen, he said, is if the signal was cut off abruptly. A comet wouldn’t produce that kind of signal, because the gases that surround them cover large, diffuse areas. Nor would the comet have escaped from the radio telescope’s field of view that fast.

Astronomers Capture Hundreds of Alien Signals From Space

Mysterious signals from 234 stars have been recorded by astronomers who believe that it could indicate the presence of extraterrestrial intelligence.

Astronomers Ermanno Borra and Eric Trottier from Laval University in Canada analyzed 2.5 million stars from the Sloan Digital Sky Survey project.

In their resulting study published in Solar and Stellar Astrophysics journal, the pair conclude that the peculiar signals they recorded could be from aliens trying to make contact with Earth.

The researchers came to this potential explanation based on a previous study by Borra which predicted the shape of an extraterrestrial intelligence (ETI) signal. The 234 signals identified match this shape exactly, reports Russia Today.

However the theory that these signals are the result of aliens is only one of a number of possibilities.

Strong Alien signal coming from nearby sunlike star sets SETI on alarm

SETI researchers are buzzing about a strong spike in radio signals that seemed to come from the direction of a sunlike star in the constellation Hercules, known as HD 164595.

The signal conceivably fits the profile for an intentional transmission from an extraterrestrial source – but it could also be a case of earthly radio interference, or a microlensing event in which the star’s gravitational field focused stray signals coming from much farther away.

In any case, the blip is interesting enough to merit discussion by those who specialize in the search for extraterrestrial intelligence, or SETI – including Centauri Dreams’ Paul Gilster, who brought the case into the public eye.

Gilster reports that the signal spike was detected more than a year ago, on May 15, 2015, by the RATAN-600 radio telescope in Zelenchukskaya. That facility is in the Russian republic of Karachay-Cherkessia, not far from the Georgian border.

Researchers who are working out the strength of the signal say that if the signal came from an isotropic beacon, it would have been transmitted by a Kardashev Type II civilization.

The Kardashev scale is a method of measuring a civilization’s level of technological advancement, based on the amount of energy a civilization is able to use for communication.

The scale has three designated categories:

A Type I civilization – also called planetary civilization – can use and store energy which reaches its planet from the neighboring star.

A Type II civilization can harness the energy of the entire star (the most popular hypothetic concept being the Dyson sphere—a device which would encompass the entire star and transfer its energy to the planet).

A Type III civilization can control energy on the scale of their entire host galaxy.

At least two SETI research groups are aiming to track HD 164595. The SETI Institute is using the Allen Telescope Array in northern California, while METI International is looking to the Boquete Optical SETI Observatory in Panama.

Mysterious ‘Wow’ Signal Not From Aliens, Argues Astronomer

Wow Signal

By Devin Coldewey

      A powerful radio signal received from space in 1977 and never explained may have been the result of a then-unknown comet, not extraterrestrials, an astronomer proposes in a new paper.

The “Wow! signal” is named after what astronomer Jerry Ehman wrote (“Wow!”) next to the paper readout of the radio telescope that recorded it. The signal was very powerful and emanated briefly from a single point in the sky, right at a wavelength many have suggested would be a natural one for extraterrestrial life to transmit in [….]

But Antonio Paris at St. Petersburg College in Florida has found that two comets, yet to be identified in 1977, were in just the right position, and due to their halo of hydrogen might have given off energy in the right wavelength. […]

ET Calling?

Source: Royal Astronomical Society paper:

The Australian Parkes radio-telescope has picked up a (FRB) Fast Radio Burst signal from deep within our galaxy. Astronomers first realized they received a signal back in 2013 while looking through archival data from “The Dish”. A team of astronomers from Swinburne University let by PhD student Emily Petroff developed a technique to look for FRBs in real time and used the 64-metre radio-telescope to experiment.

Beginning of 2015 an event was captured by Parkes radio-telescope’s real-time transient pipeline. They recorded an 8-bit full-polarization data from two orthogonal linear feeds per beam, with 1024 frequency channels over 400 MHz of bandwidth from 1182 to 1582 MHz, and 64-micro-seconds time resolution.

The FRB is well outside the Milky Way, at 5.5 billion light-years’ distance and didn’t show up in infrared or UV spectra, so while it put out energy equivalent to the Sun’s daily output in a few milliseconds, what caused the radio signal burst is still a mystery. One thought is the source of the signal was close to a strong magnetic field of unknown causes.

This hasn’t been the first time astronomers have detected some type of radio signal from space. Pulsar stars or “Radio Stars” create a signal that can be detected and recorded. These types of signals are common to the source and are easily explained, but the signals that are not easily explained, are the ones we need to be aware of like, the “Wow” signal of 1977.

The Wow! Signal: (Wikipedia)
The Wow! signal was a strong narrowband radio signal detected by Jerry R. Ehman on August 15, 1977, while he was working on a SETI project at the Big Ear radio telescope of Ohio State University then located at Ohio Wesleyan University’s Perkins Observatory in Delaware, Ohio. The signal bore the expected hallmarks of non-terrestrial and non-Solar System origin. It lasted for the full 72-second window that Big Ear was able to observe 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.

Determining a precise location of the signal was very complicated due to the Big Ear telescope’s use of two feed horns to search for signals. Each feed horn was pointing to a slightly different direction in the sky following the Earth’s rotation. The “Wow” signal was detected in one of the horns but not the other, and the data was processed in such a way that it was impossible to determine which of the two horns detected the signal, thus what direction the signal came from.

There were two possible right ascension values they could look at.
Right ascension: The point on the celestial equator which rises with any celestial object as seen from the Earth’s equator, where the celestial equator intersects the horizon at a right angle.

Based on the two right ascensions from both horns from the telescope, the region of the sky the signal came from, lies in the constellation Sagittarius. Tau Sagittarii is the closest and easily visible star from that region.

Upon multiple efforts afterwards, another similar signal was never detected.

In 1984 a California nonprofit organization received the funding they needed from NASA to officially create the SETI Institute “Search for Extraterrestrial Intelligence” a not-for-profit organization. They’re mission is: To explore, understand and explain the origin and nature of life in the universe, and to apply the knowledge gained to inspire and guide present and future generations.

SETI has been instrumental in today’s society, releasing and teaching the public about their work. With some easy research you can find all kinds of data not only about them, but also pertaining to radio signals being detected from space from other sources too! Some websites say these signals are unknown and of intelligent origin, but those claims can’t be fully verified. NASA has also been accused on multiple occasions of hiding information from the public about intelligent radio waves they’ve received; SETI has also been accused about hiding information from the public while using the very same public’s personal computers to help them find signals they supposedly feed to NASA.

In 2010 a CNN reporter talked about alien signals that were picked up, but the telecast was only aired once and never again. Is there a conspiracy to hide information from the public? I had originally heard one of the reasons CBS had fired news anchor woman Connie Chung in the 1980’s was due to an interview she did with George Magazine. The interviewer asked her how the news editor decides what topics air compared to ones that don’t? She replied, “There’s a list of topics we can’t talk about”. When I heard about this information at that time, I contacted George Magazine and was able to talk to one of its writers. He confirmed the possibility the rumor was true based on what she said in the article.

Cover-up?

japanese_balloon_bomb Today on the NPR website there’s an article, “Beware of Japanese Balloon Bombs”. The article talks about over 6000 balloon bombs launched from Japan in late 1944 towards the USA to wreak havoc on American soil. What I found interesting and find all the time is, how our government with-holds information from the public.

Direct quote from article:
All in all, the Japanese military probably launched 6,000 or more of the wicked weapons. Several hundred were spotted in the air or found on the ground in the U.S. To keep the Japanese from tracking the success of their treachery, the U.S. government asked American news organizations to refrain from reporting on the balloon bombs. So presumably, we may never know the extent of the damage.

Hiding information from the Japanese, or withholding information from the American public? Shouldn’t Americans have been told there could be a possible threat floating and landing in their back yards that could kill them? What was the real reason the government withheld the information?

Actually during the mid 1940’s, there were multiple UFO sightings reported that pertained to the Japanese Balloon bombs. Unfortunately there were some casualties due to the balloons. In the spring of 1945, a pregnant woman and five children were killed by a 15-kilogram high-explosive anti-personal bomb from a crashed Japanese balloon on Gearhart Mountain near Bly, Oregon. Supposedly those were the only documented casualties, but if the media was told not to report them, how many other Americans died?

Note: Years ago when my children were younger and shorter than me, while on vacation we visited the Bradbury Science Museum in Los Alamos, New Mexico. The Manhattan Project exhibit there includes full size models of the atomic bombs, “Little Boy” and “Fat Man”. One exhibit was viewing an old black and white movie in which the Manhattan Project went into detail. In the movie the announcer brags about how the US government yanked certain words from being published in “any” journal or media that could be associated with the project. The movie talked about words such as, “atomic” and “plutonium” among some others, which were directly pulled from the famous “Buck Rogers” comic books! So basically the US Government was able to control what was printed and what was discussed through the media back then. How about now?

If you think conspiracy theories about hiding information from the public is bull, then all you have to do is look into the history of the US. Hiding information from the public is located everywhere not only in the USA, but other countries as well. Has been, and still is, every day.

So are we receiving radio signals from intelligent life outside this planet? Well as a UFO investigator I may be a little bias in my answer, what about yours?
