Arthur T Knackerbracket has found the following story:

The perennial optimists at the Search for Extraterrestrial Intelligence, or SETI, have joined the rest of the world in deploying AI to help manage huge data sets — and their efforts almost instantly bore fruit. Seventy-two new "fast radio bursts" from a mysteriously noisy galaxy 3 billion miles [light years] away were discovered in previously analyzed data by using a custom machine learning model.

To be clear, this isn't Morse code or encrypted instructions to build a teleporter, à la Contact, or at least not that we know of. But these fast radio bursts, or FRBs, are poorly understood and may very well represent, at the very least, some hitherto unobserved cosmic phenomenon. FRB 121102 is the only stellar object known to give off the signals regularly, and so is the target of continued observation.

The data comes from the Green Bank Telescope in West Virginia (above), which was pointed toward this source of fast and bright (hence the name) bursts for five hours in August of 2017. Believe it or not, that five-hour session yielded 400 terabytes of transmission data.

Initial "standard" algorithms identified 21 FRBs, all happening in one hour's worth of the observations. But Gerry Zhang, a graduate student at UC Berkeley and part of the Breakthrough Listen project, created a convolutional neural network system that would theoretically scour the data set more effectively. Sure enough, the machine learning model picked out 72 more FRBs in the same period.

That's quite an improvement, though it's worth noting that without manual and traditional methods to find an initial set of interesting data, we would have little with which to train such neural networks. They're complementary tools; one is not necessarily succeeding the other.

New Technologies, Strategies Expanding Search for Extraterrestrial Life 5 comments

New technologies, strategies expanding search for extraterrestrial life:

Emerging technologies and new strategies are opening a revitalized era in the Search for Extraterrestrial Intelligence (SETI). New discovery capabilities, along with the rapidly-expanding number of known planets orbiting stars other than the Sun, are spurring innovative approaches by both government and private organizations, according to a panel of experts speaking at a meeting of the American Association for the Advancement of Science (AAAS) in Seattle, Washington.

New approaches will not only expand upon but also go beyond the traditional SETI technique of searching for intelligently-generated radio signals, first pioneered by Frank Drake's Project Ozma in 1960. Scientists now are designing state-of-the-art techniques to detect a variety of signatures that can indicate the possibility of extraterrestrial technologies. Such "technosignatures" can range from the chemical composition of a planet's atmosphere, to laser emissions, to structures orbiting other stars, among others.

The National Radio Astronomy Observatory (NRAO) and the privately-funded SETI Institute announced an agreement to collaborate on new systems to add SETI capabilities to radio telescopes operated by NRAO. The first project will develop a system to piggyback on the National Science Foundation's Karl G. Jansky Very Large Array (VLA) that will provide data to a state-of-the-art technosignature search system.

"As the VLA conducts its usual scientific observations, this new system will allow for an additional and important use for the data we're already collecting," said NRAO Director Tony Beasley. "Determining whether we are alone in the Universe as technologically capable life is among the most compelling questions in science, and NRAO telescopes can play a major role in answering it," Beasley continued.

"The SETI Institute will develop and install an interface on the VLA permitting unprecedented access to the rich data stream continuously produced by the telescope as it scans the sky," said Andrew Siemion, Bernard M. Oliver Chair for SETI at the SETI Institute and Principal Investigator for the Breakthrough Listen Initiative at the University of California, Berkeley. "This interface will allow us to conduct a powerful, wide-area SETI survey that will be vastly more complete than any previous such search," he added.

    Let's not bullshit here. We all know this is Independence Day. These new discoveries are why the FBI suddenly shut down that New Mexico observatory.

    Also, Robert Mueller so far has a perfect record of getting guilty pleas in every single case he's prosecuted arising out of the Trump/Russia investigation. So, it appears our fearless leader is about to receive not one, but two anal probes. One from the aliens who are totally about to land and the other from the Special Counsel's office.

    Although, if they land on the White House lawn and demand to be taken to our leader, Trump might very well just point them to Vladimir Putin.

      If we don't even know the nature of the object/event, it's hard to come up with a good name. The FRB source may be transient, which would be a waste of a name.

      For example, 2014 MU69 [wikipedia.org] won't/shouldn't get a real name until we know whether it is one or two objects.
