SETI@Home Search For Alien Life Project Shuts Down After 21 Years (bleepingcomputer.com) 85

An anonymous reader quotes a report from Bleeping Computer: SETI@home has announced that they will no longer be distributing new work to clients starting on March 31st as they have enough data and want to focus on completing their back-end analysis of the data. SETI@home is a distributed computing project where volunteers contribute their CPU resources to analyze radio data from the Arecibo radio telescope in Puerto Rico and the Green Bank Telescope in West Virginia for signs of extraterrestrial intelligence (SETI).

Run by the Berkeley SETI Research Center since 1999, SETI@home has been a popular project where people from all over the world have been donating their CPU resources to process small chunks of data, or "jobs," for interesting radio transmissions or anomalies. This data is then sent back to the researchers for analysis. In an announcement posted yesterday, the project stated that they will no longer send data to SETI@home clients starting on March 31st, 2020 as they have reached a "point of diminishing returns" and have analyzed all the data that they need for now. Instead, they want to focus on analyzing the back-end results in order to publish a scientific paper.
SETI@Home has a list of BOINC projects on their website for those interested in donating their CPU resources.

        I doubt those last two parts can be properly quantified by the SETI team, but I would expect the scientific paper they alluded in the summary to answer the former.

        AFAIK that distributed computing planet finder has done some quite good work, as has folding@home.

        SETI searches were always going to be a little more needle-in-haystacky, I fear, with the results more "a chance of something amazing" than slight incremental increases in knowledge with work contributed.

        *PERSONALLY* I've always believed the SETI listening thing to be nearly pointless, basing the work on too many anthropocentric assumptions.

        I believe firmly that it's a near certainty that there's other intelligent life out there. I just think that the odds are that they are vastly more advanced than we are that they're incomprehensible. If we're talking BILLION+ years of advancement differential, that's the difference between primitive multicellular life forms on earth...and us. Assuming those primitive eukaryotes had intelligence...in what possible context could they even conceive of humans, much less perceive them, or communicate with them?

            Actually if you look at earth's history it got many mass extinctions that set evolution back for tens or hundreds of millions of years each. We just know that life has begun here, not whether this is a particularly good place to start. For all we know this might be a marginally habitable planet while other planets had a billion years of unbroken, rapid progression and did in a hundred million years what took us a billion.

            The first six or eight billion years there hadn't been enough supernova explosions to build up the heavier elements that we need, IIRC the heaviest that standard solar fusion can make is lithium. Everything else is from multiple generations of supernovas and possibly neutron star collisions.

            Our sun condensed out of a cloud of dust containing enough heavy elements to make at least 4 rocky planets, and life appears in the fossil record just about as soon as it was possible to form. And then it stagnated at

              I think you are talking about "primordial nucelosynthesis", when the immediate post-Big Bang soup of nucleons formed a moderate amount (~25% nucleus count) of helium and a trace of lithium.

              Large stars - above a couple of solar masses - can form nuclei up to CNO-ish, but it is hard to get the stuff out again since you need to go up to about 6 or 8 solar masses to get a good supernova going, at which point you start spraying heavy nuclei back o

                I had forgotten about white dwarf collisions, I don't think they've been observed yet, have they? Neutron star collisions have been, and the outputs detected seem to indicate large amounts of higher order elements being spewed out as a result.

                • I think you're right on that, at least as far as consensus goes. The last couple of decades have had quite a bit of chatter about supernovae with peculiar light curves, as part of the "cosmic distance ladder", and as it's corollary, the discovery of "dark energy", and I think the option has come up in some of those discussions, but not to the point of achieving a consensus.

        • The chief problem with SETI always boils down to a matter of distances. Unless an alien civilization exists no more than a few dozen light years from Earth, stray signals from their version of "I Love Lucy" will become diffused and ultimately unrecognizable due to the expanding light cone and all the other noise in interstellar space.

          The only signals more than a few dozen light years we have a chance on seeing would be very high powered directional signals. In other words, an alien civilization would have t

            Too bad they didn't spend a century or two building whole new types of telescopes, arrays of telescopes orbiting their star, forming a mass interferometer. With that kind of technology it's quite conceivable that they would have been able to (obtain) much more detailed images of exoplanets, potentially even imaging geological features like oceans and c

          On the opposite end of the spectrum, it's possible that we are among the first systems with both intelligent life, and sufficient natural resources for a technological civilization. The reason being is that earlier generations of stars formed out of nebulae with relatively low concentrations of the heavier elements. It took several generations of stars forming, dying, and blasting out their remains in super novae for a system like ours to form which has enough heavy elements for not only life, but for mod

          • very implausible. carbon, nitrogen, oxygen, silicon and iron became available en masse around six or seven billion years ago already, and that doesn’t discount the possibility that some terrestrial planets could have formed earlier, but just with less frequency. so some terrestrial worlds might have billions of years' head start over us, unimaginably long by civilisation scales

          Personally, I think that's what the "back-end analysis" is that they're talking about (though I really don't know for sure how the project was laid out). The distributed work was to take the signal data and look for anything that might conceivably be useful data, in mathematical rather than anthropocentric terms. Fourier transforms for periodic components, matching signals on different frequencies, and things like that. It's nothing that would say "here are aliens", but more "This is what the data looks lik

      They haven't. Their code is open-source, others have compiled it better for faster compute times, and their own code just doesn't draw enough power to be doing mining.

One of the recurring tasks is comparing repeated observations of the same part of the sky, which will need to be re-processed each time the telescope goes back to observe the same region again. (You do know that the SETI@Home data was collected from "parasitic" observations - if the telescope went back to look at a partic

      Yes.

      The result was that, with the sheer amount of processing power available to the SETI / BOINC projects... there was no easily-discernible SETI-interest signals.

      Negative results are just as important as positive. And in the process it spawned BOINC which is/was doing things like protein-folding and all sorts of things that are literally making pharmaceuticals and helping cure cancer.

      For zero public-funding costs, we have found a huge range of positive science, and confirmed the hypothesis that any SETI signal would be rare and unusual. And mostly with "idle" CPU time that would have done nothing otherwise.

      Even accounting for the "cost" of the exercise... you got something out of it for far less than, say, a Microsoft datacentre puts out.

    Folding@Home is helping with diseases, and is probably the most helpful overall. Others have helped find prime numbers that help keep data secure. Still others have simulated things that help with agriculture and disease mitigation and things of that nature. Sure, it would have been possible without S@H, but I think the project was the first one to gain enough traction to show that "1,024 chickens" was just as viable as renting time on a Blue Gene, and that there was enough public interest to justify using it elsewhere.
