AI identifies possible alien technosignatures in deep space

Astronomers at SETI have been using artificial intelligence to aid in their hunt for signs of intelligent alien life.
Founded in Mountain View, California back on November 20th, 1984, the SETI Institute has made it its mission to systematically scan the skies for evidence that we are not alone in the universe.

One of the ways in which it is doing this is to scour the heavens for signs of extraterrestrial technology (especially large objects like Dyson Spheres) far out in space.

Finding these 'technosignatures', however, is like looking for a needle in a very big haystack indeed.

More recently, though, advances in artificial intelligence have made it possible to enable a computer to do a lot of the work and to pick out possible signals of interest that humans could easily miss.
Now in a new paper, scientists have detailed the discovery of 8 potential alien technosignatures in data collected in 2016 that has since been analyzed by a complex machine-learning algorithm.

In total, the system went through 480 hours of data collected from 820 star systems.

The candidate signals have been described as "narrow band, doppler drifting signals originating from some extraterrestrial source", though it currently remains unclear what is producing them.

It will take further study and analysis to either confirm or rule out their significance.

Either way, these findings demonstrate the effectiveness of using AI for tasks of this nature and even if these particular candidates turn out to be nothing, there is every chance that, one day in the not-too-distant future, SETI will find the signal that will answer the question "are we alone?" once and for all.

Example of AI intelligence and "useful" advice.† The future is dumb and awfully boring†

That's my advice too†

Sure you can, when you apply logic and reason along with science.†BOOM! waved off just like that.† The amount and degree some jump to conclusions around here is astounding.

AI is only good at hiding the human hands guiding it.

I think that is different than narrow band doppler signals, but still interesting.

Failing to do your research and waving it off doesn't make your reasoning correct, however. Narrow band doppler signals coming from those 8 planets are the first known sources that arent man made. I am aware there are other radio signals from other sources. But pay attention to the specific type of signal that was found or research why seti is searching for that particular type. These are the first non-man made signals like this found. They are finely tuned signals that eliminate static, like humans use for radio communication. Not like radiation radio from jupiter. Hence the reason they are d... [More]

Failing to actually tread the paper and understand what was published doesn't make what you've posted correct. I recommend you take the time to 1, read the paper and 2, do follow on reading on what sorts of signals are detected and dismissed by various scientific agencies.†

You call them planets. I do not. Calling them planets is merely the - erroneous - supposition of some people that drifting doppler signals are conclusively indicative of planets. Whereas in fact there is no unambiguous evidence whatsoever that these eight stars have planets. † Eight alien species discovered after observing only 820 stars? That is ludicrous. Do observe that they speak of star systems, implying that those stars have planets. They do not. There is no conclusive evidence that any of those stars has a planet. Do observe that they use the word extraterrestrial, implying that those a... [More]

Many years back i lost a good friend who hit me to go thrifting i said i cant having a bad nerves day panic, she knew about it yet replies yeah well if i have a panic attack i dont let it stop what im doing i just make it go away and so could you, i said no, i cant, she didnt speak to me for months. Hum maybe kimmie was actually AI.

Im not saying you are being credulous but you arent basing your opinions in proven science either.
