Alien Hunters Discover Mysterious Signal from Proxima Centauri

It’s quite possible but
It’s as ridiculous to say “there is” as it is to say “there isn’t” and then to look down on anyone who doesn’t agree as the op did

They haven't ruled out all potential sources, so who knows it could be aliens.

The article could be wrong about technosignatures, I would imagine leaps in alien technology would be totally different from ours. There is over a century of human communications flying through the space-time continuum.

Instead of centuries, an alien technosignature could span in months or years... for every human year, an alien ages seven. Doggy years.... possible lol. ; )

The signal 982MHZ has no modulation and it drifts, that could mean the source is moving like a satellite around it's star or planets etc.. It's like a deadkey signal or like someone didn't hang up the phone. We use signals like that for tracking, navigation and in conventional electronic controls etc... so yeah, could still be alien.

Just because it's outdated, "982 MHz" and not a quantum communication system, that doesn't rule out aliens. It could very well be an alien technosignature.

I'm not saying it's aliens, but it's possible.

Seth Shostak must be pulling his hair out....how could he have missed this after searching radio signals from stars most of his life.. Worse, the nearest star to our own star..

To me, if it is a made signal it can only be from a civilization technological advanced like ourselves. Searching for communication signals like he does is a complete waste of time... An intelligent species would use the properties of entanglement to comunicate over long distances...only that way you can have instant contact with someone at the other side of the universe...galaxy..solar system....

The Proxima Centauri signal *appears* to have no modulation. We don't have the observational details yet, but they could well have used a long integration time, which would smear out details like modulation. Readings over a considerable length of time would have been averaged out to a single value. This would make sense, since the signal was turned up by a project looking for relatively long-lived stellar flares, not communication activities. Readings are strengthened by long integration times. The signal was only analyzed for SETI content long after it was received, and had been archived.

The SETI analysis used FFT and Gaussian filtration that would have been able to quickly tell if there was any underlying carrier and modulation. We have so much data to analyze that findings like this have to be sidelined as natural phenomena and than the computers say "next".

There is still quite a backlog of raw data, however the loss of Aricebo will quickly become evident. That machine was a wonder of our times and it is now in such a state that it will probably be abandoned due to the vast amount of money it would take to rebuild it.

Many know of the 2-phase catastrophy, but you may have never seen this view of #2. I am a member of the community and submit to you these 2 views , which are incredible as they are sad..

Just supposing for the moment that the Proxima signal is a genuine SETI signal-- Why would it have a radio frequency very near just three times that of the well- known ( at least to radio astronomers) spectral line for deuterium?
Perhaps because of the unique structure of the deuterium atom-- 1 proton, 1 neutron, and 1 electron. 1+1+1 =3.
This wouldn't be a bad way for an intelligent form of life to reveal its knowledge of the make up of a deuterium atom. . .

How many light years is the Centauri system from us? 10 or something?

Actually Google says it's only about ~4.3 light years.

SETI has probably canvased that area of the sky dozens if not hundreds of times. If the signal really is from that system, and it was only detected recently, then Seth is probably not too upset.

My money is on either a more localized signal origin, or a natural phenomenon.

It's human nature to be an arrogant know it all when it comes to space. All one has to do is spend 5 mins in these sub forums to see how narrow minded we as a species are.

Or a secret aircraft that stays at high altitudes for prolonged periods of time.

Interesting site that discusses the ongoing work into quantum communications.
