It was a comet, they report, one that that was unknown at the time of the signal discovery. Lead researcher Antonio Paris describes their theory and how the team proved it in a paper published in the Journal of the Washington Academy of Sciences. Back in August ofa team of astronomers studying radio transmissions from an observatory at Ohio Stammor och emissioner 2008 06 02 called the "Big Ear" recorded an unusual second signal—it was so strong that team member Jerry Ehman scrawled "Wow!
Since that time, numerous scientists have searched Stammor och emissioner 2008 06 02 an explanation of the signal, but until now, no one could offer a valid argument.
Possible sources such as asteroids, exo-planets, stars and even signals from Earth have all been ruled out. Some outside the science community even suggested that it was proof of aliens.
It was noted that the frequency was transmitted at 1, MHz, though, which happens to be the same frequency as hydrogen. The explanation started to come into focus last year when a team at the CPS suggested that the signal might have come from a hydrogen cloud accompanying a comet —additionally, the movement of the comet would explain why the signal was not seen again. The team noted that two comets had been in the same part of the sky that the Big Ear was monitoring on the fateful day.
The team then got a chance to test their idea as the two comets appeared once again in the night sky from November through February of To verify their results, they tested readings from three other comets, as well, and found similar results. The researchers acknowledge that they cannot say with certainty that the Wow!
Report suggests famous radio telescope signal was caused by comets. From 27 November to 24 Februarythe Center for Planetary Science conducted observations in the radio spectrum to validate the hypothesis.
During observations of the comet, a series of experiments determined that known celestial sources at MHz i. During this experiment, the During observations of these comets, we detected a radio signal at MHz. The results of this investigation, therefore, conclude that cometary spectra are detectable at MHz and, more importantly, that the "Wow!
Comets get blamed for everything. Pestilence in medieval Europe? Even the anomalous brightness variations in the Kepler star KIC was blamed for a time on comets. Now it looks like Comets are chunks of ice and dust that orbit the sun, usually A trip past the sun may have selectively altered the production of one form of water in a comet - an effect not seen by astronomers before, a new NASA study suggests. Scientists from the University of Arizona's The mystery of where Earth's water came from got murkier Wednesday when some astronomers essentially eliminated one of the chief suspects: Scientists have found evidence that dark matter can be heated up and moved around, as a result of star formation in galaxies.
The findings provide the first observational evidence for the effect known as 'dark matter heating', An international group of astronomers has detected an intense and extremely luminous gamma-ray flare from one of high-redshift blazars known as DA The new detection, reported in a paper published December 18 on arXiv. China's burgeoning space program achieved a lunar milestone on Thursday: NASA spacecraft 4 billion miles from Earth yielded its first close-up pictures Wednesday of the most distant celestial Stammor och emissioner 2008 06 02 ever explored, depicting what looks like a reddish snowman.
Using observations from the ALMA radio observatory in Chile, researchers have observed, for the first time, a warped disk around an infant protostar that formed just several tens of thousands of years ago.

This is a reminder that intelligent aliens doing wacky and detectable things nearby is always the last answer you want to consider for any perplexing phenomenon like the variable light of KIC Given the vastness of the universe, aliens capable of using radio technology are probably out there, but it seems clear they are either intentionally keeping a low profile, don't use radio signals, or don't use radio signals we are set up to detect at the moment.
I learned this from surviving Heavens Gate member s. While the comet theory is possible, so is an alien transmission. Don't that inwe beamed a powerful one-time burst of a Megawatt at star cluster M Surely it would have been known before now if comets emit a radio signal at MHz. Hundreds of them have been investigated but it took until now Stammor och emissioner 2008 06 02 draw a link with the Wow signal?
Sounds an over-simplification to me. Hmmmm, M13 is 22, light years away. I don't think the signal has reached there yet. Sinceour signal has gone only 43 light years or so, and in addition I don't think there is a star that close to the line-of-sight to M13 that could have received it yet.
Perhaps I misunderstood your point. It's worth noting that this is one of the spectral lines of hydrogen, as mentioned in the article.
Also worth noting that the abstract of the paper says they not only checked their results by moving away from the comet, but also checked other comets and found the same signal. It doesn't appear anyone checked comets with radio telescopes looking for this spectral line until now. The SETI people are constantly searching for this spectral line but have turned up nothing. Which seems unlikely if comets are such a frequent source of Wow-type signals.
Let's ask a fairly obvious question here: Why not choose a quiet frequency band where someone might actually hear you? Well, I don't pretend to understand alien intelligence. But if I could encode the message inside a photon property that could be distinguished from the dumb water molecules, the H noise would be a feature not a bug. Like modulating photon spin. Or maybe there's a tech I'm not guessing that sends a coherent signal through the noise, and exploits all that intermediary H as hops in a transmission medium.
I know those aren't completely working explanations, but they're possibilities that the H could have some advantages if the unknown means of exploiting them could be achieved. Nice study but poor diction. The idea is not to look at these frequencies but in the relatively quiet range between them specifically the range between the hydroxyl and the hydrogen emission lines - which is called the 'water hole' in SETI https: To speculate, they could use the interference to decrease the chances of an unintended interception of their messages.
A randomly noisy frequency should reduce the detectable range of the signal because all the interference would make it difficult to isolate the actual signal. A related approach might overlay a spread spectrum transmission over a noisy, wide-range frequency band.
Again this would be to minimize the chances of unintended interception. I don't think this is actually happening nearby, because I don't think radio-using aliens are anywhere close for other reasons. However, if true, it would tell us a lot about what the aliens believe, i. A better explanation "Stammor och emissioner 2008 06 02" "aliens", because the comet theory is reproduced.
That is what "relative assurance" means. Your complaint is a strawman fallacy. Also I don't think you know what "diction" means. A randomly noisy frequency should reduce the detectable range of the signal That is an interesting point supporting the utility of radio signals within a spatial range empty of the noise sources.
Which made me think that even outside the quiet spatial range of the signal could be differentiated from the noise on the same frequency if the transmitter position is distinguished from the noise sources. So if multiple antennas are used in a phased array, as humans have been doing for some years now, the position of the source can be detected to distinguish it from noisy water sources. And indeed phased arrays can transmit a shaped beam that could point through noisy haze to a single receiver not phased array antenna that's pointed along the Stammor och emissioner 2008 06 02. And it seems possible to stimulate distant water Stammor och emissioner 2008 06 02 located in a phased array with say a microwave laser to resonate Stammor och emissioner 2008 06 02 into transmitting a shaped beam.
Indeed the phased array of comets could orbit. The idea is not to look at these frequencies but in the relatively quiet range between them But this one's right on the frequency. That was my point. I thought you were referring to the general SETI efforts in your post since you were talking about frequency band and not a specific frequency.
I don't think that comets are te source of WOW. BigEar didn't see these objects. If you want people to read your argument, and perhaps to reply, you'll be better served by posting here at least a summary of your argument.
Then maybe people will read your longer document to which you link. Or else you can reply to them again citing it by link. It was running in DriftScan. The globe is rotating with 0. With this parameters, I calculate the size RA angle only of the object. If I assume a small fixed point source far far away, then only the RA width of 0. The time, which an object of 0. I put the eye of the beamwidth and the assumed comets diameter in the starmap and they didnt cover.
I'm not that scientifically literate to be honest, but interested in this stuff once it has been dumbed down for me in articles.
