A Breakthrough in the Search for ET Intelligence?

• Researchers at University of Manchester in the UK have developed a new analytical technique that they say represents “a milestone in SETI”, the ‘search for extraterrestrial intelligence’. Making use of new data being gathered by European Space Agency’s ‘Gaia’ satellite, this “analytical technique” will “place limits” on the probability of other extraterrestrial intelligence in the Milky Way.

• In a new research paper published on September 2nd in the journal Monthly Notices of the Royal Astronomical Society, University of Manchester astronomers Bart Wlodarczyk-Sroka and Michael Garrett, in collaboration with Andrew Siemion, the director of the Breakthrough Listen Initiative (at SETI), have increased the number of stars available for applying SETI search criteria by more than 200 times – from 1,327 to 288,315 stars.

• The Gaia spacecraft satellite and observational platform is currently gathering a vast quantity of data to create the first-ever three-dimensional map of our Milky Way galaxy. SETI estimates that fewer than 0.04% of stellar systems have the potential of hosting an advanced civilization with at least 21st century radio technology. “Combing through the catalogue produced by the ESA’s Gaia spacecraft, which measured the distances to over a billion stars,” reads the report, “[we] recalculated limits on the prevalence of transmitters around additional stars within the radio telescope’s fields of view. By selecting stars out to much larger distances (up to about 33,000 light years) than the original sample of nearby stars, [we] were able to expand the number of stars studied from 1,327 to 288,315.”

• In other words, Wlodarczyk-Sroka and Garrett have extrapolated this 0.04% standard to a much larger field of data – representing 200 times the number of stars that it was once applied to – to ‘place some of the most stringent limits to date on the prevalence of powerful radio transmitters in this region of our Milky Way galaxy’. This SETI-approved 0.04% probability of other advanced civilizations out there doesn’t include non-technical ‘simple life’ civilizations.

• Team leader Mike Garrett is glad that SETI searches can now take into account the many other ‘cosmic objects’ (ie: exoplanets) that fall within the range of the ESA telescope, and apply the same SETI limits to 287,000 more star systems. “Knowing the locations and distances to these additional sources greatly improves our ability to constrain the prevalence of extra-terrestrial intelligence in our own galaxy and beyond,” said Garrett. “We expect future SETI surveys to also make good use of this approach.

• According to the report’s conclusion, “fewer than 0.04% of stellar systems have the potential of hosting advanced civilizations with the equivalent or slightly more advanced radio technology than 21st century humans. As well as improving the limits for nearby stars, the team for the first time have actually placed limits on more distant stars with the caveat that any potential lifeforms inhabiting the outer limits of the galaxy would need even more powerful transmitters in order to be detectable.”

• “Our results help to put meaningful limits on the prevalence of transmitters comparable to what we ourselves can build using 21st century technology,” said Wlodarczyk-Sroka. “We now know that fewer than one in 1,600 stars closer than about 330 light years host transmitters just a few times more powerful than the strongest radar we have here on Earth.”

[Editor’s Note]   Is this what they call hiding the deceit in plain sight? Is the deep state’s SETI admitting that they are simply extrapolating its 0.04% probability estimate of advanced ET beings in the galaxy to more and more stars as they are discovered? And how do they arrive at this ‘1 in 1,600 stars’ probability in the first place? Their false narrative is that there must be some other intelligent civilization out there in this vast galaxy, but we have a pathetically small chance of ever detecting them, much less meeting them. Now, if this was a true analytical probability, it would presume that they actually discovered some of these civilizations through returned radio transmissions to compute a ratio. This hasn’t happened, not according to SETI. But SETI isn’t so much in the business of actually finding evidence of intelligent extraterrestrials as they are in looking for them. So all that this prestigious university report does is to arbitrarily “place” SETI’s pseudo-scientific “limits” on any new stars that the highly advanced ESA space observatory finds. Yay.

The researchers called their new analytical technique “a milestone in SETI.” One researcher commented: “We now know that fewer than one in 1,600 stars closer than about 330 light years host transmitters just a few times more powerful than the strongest radar we have here on Earth.”

Astronomers at the University of Manchester in the UK said today (September 2, 2020) that they’ve made an

analytical breakthrough in the ability to seek and perhaps someday find intelligent extraterrestrial life in our Milky Way galaxy. They said this breakthrough is a “milestone” that could “significantly improve” our chances of finding extraterrestrial intelligence by dramatically expanding the number of stars available for searching. They said their new analytical technique has increased the number of stars that can be analyzed by more than 200 times. And they said they’ve now placed the best limits yet on the prevalence of artificial radio transmitters, dubbed techno-signatures, in the Milky Way.

In new research published on September 2 in the peer-reviewed journal Monthly Notices of the Royal Astronomical Society. In a statement the researchers said: “The collaborative research team have been able to dramatically expand the search for extra-terrestrial life from approximately 1,400 stars to 280,000 – increasing the number of stars analyzed by a factor of more than 200 …”

“The result suggests that fewer than 0.04% of stellar systems have the potential of hosting advanced civilizations with the equivalent or slightly more advanced radio technology than 21st century humans. As well as improving the limits for nearby stars, the team for the first time have actually placed limits own more distant stars with the caveat that any potential lifeforms inhabiting the outer limits of the galaxy would need even more powerful transmitters in order to be detectable.”

The research team consists of University of Manchester Masters student Bart Wlodarczyk-Sroka and his advisor Michael Garrett, collaborating with Andrew Siemion, director of the Breakthrough Listen Initiative.

The analysis, say researchers, can only locate intelligent and technically advanced civilisations that use radio waves as a form of communication. They could not, for example, detect ‘simple’ life or non-technical civilizations. They said: “Combing through the catalogue produced by the European Space Agency’s (ESA) Gaia spacecraft, which measured the distances to over a billion stars, [we] recalculated limits on the prevalence of transmitters around additional stars within the radio telescope’s fields of view. By selecting stars out to much larger distances (up to about 33,000 light years) than the original sample of nearby stars, [we] were able to expand the number of stars studied from 1,327 to 288,315.”

My Dad Launched the Quest to Find Alien Intelligence

Article by Nadia Drake                               June 22, 2020                           (nationalgeographic.co.uk)

• In the spring of 1960, with a budget of less then $2,000 and access to an 85-foot radio telescope in Green Bank, West Virginia, a 29-year-old astronomer named Frank Drake set out to look for signs of intelligent alien life beyond Earth. For three months, the telescope scanned its targets and found nothing more than cosmic static.

• Back in the 1960s, astronomers knew of no worlds beyond our solar system. But Drake reasoned that other worlds might be populated by civilizations advanced enough to broadcast their presence to the cosmos, as we on Earth had been doing for decades. “Searching for intelligent life was considered bad science in those days,” says Drake, who just turned 90 years old.

• So Drake designed an experiment called Project Ozma, after the princess in L. Frank Baum’s Oz series. Even though Ozma failed to find evidence of extraterrestrial technologies, the project was the first step toward solving a monumental mystery. In 1961, the National Academy of Sciences asked Drake to convene a meeting at Green Bank to further discuss the search for intelligent life. While organizing that meeting, he casually came up with the now-famous ‘Drake Equation’, a framework for estimating how many civilizations might be detectable in the Milky Way galaxy.

• Project Ozma was transformed into the Search for Extraterrestrial Intelligence, or ‘SETI’. “There were radio astronomers all over the place who wanted to do SETI searches,” says Drake. But SETI projects in the US, Australia and Europe failed to gain ground. “It still had this problem of being considered flaky stuff.”

• In the Soviet Union, however, astronomers learned of Ozma and eagerly started scanning stars for signs of life. “There were far fewer restrictions on what Soviet scientists could do. They had kind of steady budgets because of the way the centralized communist government worked. They could kind of do whatever they wanted,” said science historian Rebecca Charbonneau of the University of Cambridge.

• The Soviets and Americans would meet to exchange ideas about searching for intelligent life. While the Cold War raged, U.S. and Soviet astronomers worked congenially in competition to first detect extraterrestrial life. After the fall of the Soviet Union, the relationship morphed into friendship within a global community.

• SETI had been funded by NASA. But by the 1990s, Congress began to cut federal funding for SETI projects, calling it “Martian hunting” and a waste of taxpayer dollars. The nonprofit SETI Institute, founded in 1984 at the University of California, Berkeley, was on its own.

• But in 1995, astronomers discovered the first ‘exoplanet’ outside of our own solar system. It was a Jupiter-like world, called 51 Pegasi b, orbiting a sun-like star. But it was considered inhospitable for life as we know it. Since then, astronomers have discovered thousands of exoplanets with many having conditions favorable to life. We’ve learned that planets vastly outnumber stars in the Milky Way, providing billions of places for intelligent alien civilizations to exist.

• In 2015, a 10-year, $86 million project called Breakthrough Listen was funded by Silicon Valley tech investor Yuri Milner to harnesses the world’s sharpest radio telescopes, such as the Green Bank Telescope in West Virginia and the Parkes Observatory in Australia, to search the nearest million stars for signs of extraterrestrial intelligence. Now, halfway through its tenure, it has yet to find any. It will soon add to its search the MeerKAT array of radio dishes in South Africa.

• Astronomers have expanded their search parameters beyond interstellar radio signals. They now also look for optical pulses, waste heat generated by powerful civilizations, and any other signs known as ‘technosignatures’. One of these projects is called PANOSETI, designed to scan the entire sky for fleeting but intense flashes of optical and infrared light. Led by Shelley Wright, an astronomer at the University of California, San Diego, the project will capture information about transient astronomical phenomena such as supernovae —and, just maybe, artificial transmissions.

• Today, some say that SETI is in the midst of a renaissance. Large projects are kicking off, funds are materializing, and astronomy courses now include a broader perspective on humanity’s place in the universe. If SETI can maintain its current momentum, astronomers are optimistic that future projects could be even more ambitious – maybe even installing a radio telescope on the far side of the Moon, the only place in the solar system where Earth’s constant transmissions don’t overwhelm radio signals from the cosmos.

• SETI astronomers believe that they may soon discover another extraterrestrial civilization. Or we may be the only active civilization at this moment in time. Other civilizations may have risen and fallen during the 13.8-billion-year history of the universe. It make take a few million more years for nascent lifeforms on exoplanets to evolve complex metabolisms and technological intelligence.

• In any case, the answer to Frank Drake’s question of “where are the extraterrestrials” has the potential to change the course of humanity’s future. Drake says that he didn’t anticipate how captivating the search would be, or how SETI would grow into the enterprise it is today, although it still hasn’t completely shed the “giggle factor”. Public funding is difficult. The field has relatively few dedicated practitioners, and it has yet to fully infiltrate the halls of academia. But momentum is gathering.

• [Editor’s Note]   I have no doubt that Frank Drake was sincere in his initial Ozma quest to detect errant radio signals from space to try to discover other intelligent civilizations in the galaxy. Likewise, Frank’s daughter Nadia has every reason to be proud of her father. But just like the rest of us, the Drakes and other honest astronomers have been obstructed by the deep state. While from the 60s to the 80s, the deep state allowed NASA funding of SETI efforts, they knew that technology embargo and the ‘giggle factor’ which the deep state had imposed on the scientific community would prevent SETI from finding anything or being taken seriously. By the 1990s, conventional technology was rapidly developing, so the deep state government cut off funding and infiltrated these programs with counter-productive deep state operatives. Those who now run SETI are only interested in using the project for disinformation purposes – to satisfy the public that smart people are working diligently but fruitlessly to discover evidence of another intelligent civilization in our galaxy, because these extraterrestrial beings simply don’t exist. In reality, intelligent extraterrestrial worlds permeate this galaxy and the entire universe. The elite deep state hierarchy has secretly been working with these extraterrestrials since World War II. During the past seventy years, they have developed a handful of secret space programs, including bases and colonies on the Moon, on Mars, and on celestial bodies throughout the solar system and beyond. As Richard Dolan famously put it, our shadow government has created a ‘breakaway civilization’, concealed from the people on Earth who serve as unwitting slaves to generate an industrial economy for these elite ‘puppet masters’ to utilize for their own purposes, which excludes the rest of us.

 

     Frank and Nadia Drake

In the spring of 1960, a 29-year-old astronomer with streaks of preternaturally white hair and a devil-may-care attitude set out to tackle one of humanity’s most existential questions: Are we alone in the universe?

Frank Drake, then an astronomer at the National Radio Astronomy Observatory, was gearing up to search for radio whispers from faraway civilizations that might be sailing the cosmic sea. For such a grand quest, he had a budget of £1,600 and access to a radio telescope thought to be sensitive enough to detect transmissions from any potentially broadcasting extraterrestrials.

          Nadia Drake

“Searching for intelligent life was considered bad science in those days,” says Drake, who just turned 90 years old—and is better known to me as Dad.
At the time, looking for evidence of alien technologies was still squarely in the camp of schlocky science fiction. But for my dad, it was worth taking a risk to find out if the cosmos is as richly populated as Earth’s teeming oceans—or if humanity is adrift in a profoundly quiet interstellar expanse.

Humble and curious, with a knack for quiet mischief, Dad is committed to his science, still writing research papers and serving on committees. My early memories are full of trips to observatories and conferences, and the singular pleasure of staring through telescopes at the twinkling sky. I was never bitten by the academic astronomy bug, though.

               Rebecca Charbonneau

It wasn’t until I began working as a science journalist that I realised just how risky and revolutionary Dad’s early work really was.

First light

Astronomers knew of no worlds beyond our solar system back in the 1960s, but Drake reasoned that if planets like Earth orbited stars like the sun, then those worlds might be populated by civilisations advanced enough to broadcast their presence to the cosmos. His logic made sense: For the last century, Earthlings have been making these sorts of announcements all the time in the form of TV and radio broadcasts, military radar, and other communications that leak into space.

               Shelley Wright

So he designed an experiment to search for signals coming from worlds that could be orbiting the nearby stars Epsilon Eridani and Tau Ceti. He named the experiment Project Ozma, after the princess in L. Frank Baum’s Oz series—an homage to an adventure tale populated by exotic and unearthly beings.

Before sunrise on April 8, 1960, Drake climbed an 85-foot radio telescope in Green Bank, West Virginia, jammed himself inside a trash-can-size piece of equipment, and launched humanity’s first scientific search for extraterrestrial intelligence—now known as SETI. For three months the telescope scanned its targets and found nothing more than cosmic static. The stars were stubbornly quiet.

“That was a disappointment,” Dad told me a few years ago. “We’d hoped that, in fact, there were radio-transmitting civilisations around almost every star.”

NASA to Fund Search for Signs of Alien ‘Technosignatures’ and Air Pollution

Article by Jamie Carter                           June 19, 2020                             (forbes.com)

• In the first NASA non-radio technosignatures grant ever awarded, and the first NASA grant in over three decades connected with SETI (the Search for Extraterrestrial Intelligence), NASA has awarded the University of Rochester (NY), Harvard University and the Smithsonian funding for a study entitled: Characterizing Atmospheric Technosignatures, to find ‘technosignatures’ that would indicate the presence of life on exoplanets within another star system.

• Technosignatures are scientific evidence of past or present technology similar to the type that we produce here on Earth. “Such signatures might include industrial pollution of atmospheres, city lights, photovoltaic cells (solar panels), megastructures, or swarms of satellites,” said Harvard’s Avi Loeb. The study will focus first on finding evidence of solar panels and chemical pollution. The presence of chlorofluorocarbons in exoplanetary atmospheres could indicate the presence of industrial activity.

• “There are only so many forms of energy in the Universe,” said Adam Frank at the University of Rochester. Any alien civilization is bound to have thought of solar power generation. “The nearest star to Earth, Proxima Centauri, hosts a habitable planet, Proxima b. The planet is thought to be tidally locked with permanent day and night sides,” said Loeb. “If a civilization wants to illuminate or warm up the night side, they would place photovoltaic cells on the day-side and transfer the electric power gained to the night side.”

• Some astronomers believe that technosignatures may be simpler to find than evidence of microbial life—known as ‘biosignatures’ – which detect chemicals such as oxygen and methane. Says Loeb, “If another civilization had been doing it for much longer than we have, then their planet’s atmosphere might show detectable signs of artificially produced molecules that nature is very unlikely to produce spontaneously.”

• In the past five years, many thousands of exoplanets have been discovered, some of which are in their star systems’ habitable zones and could have water vapor in their atmospheres. “Now we know where to look. We have thousands of exoplanets including planets in the habitable zone where life can form,” says Frank. “The game has changed.” Loeb’s hope is that “[by] using this grant, we will quantify new ways to probe signs of alien technological civilizations that are similar to or much more advanced than our own.” The scientists eventually want to begin an online library of technosignatures that astrophysicists can use when gathering data.

[Editor’s Note]   This is just more time and money wasted by deep state-controlled institutions such as Harvard and the Smithsonian (and now add the University of Rochester to the list) who only want to hide the fact that since at least WWII, the US government and the cabal elite have known of the presence of intelligent extraterrestrial beings and civilizations permeating our galaxy and universe, and have been secretly studying and working with these beings to their own ends, which has nothing to do with elevating human development here on Earth. They have no intention of “discovering” and revealing to the public any extraterrestrial civilizations.

 

Space agency NASA has awarded a grant to a group of astronomers to search the Universe for signs of alien civilizations via “technosignatures”—and it will focus first on finding evidence of solar panels and chemical pollution.

                 Adam Frank

Technosignatures are scientific evidence of past or present technology, which of course would indicate the presence of life in another star system. Some think that these technosignatures may be simpler to find than direct evidence of microbial life—known as biosignatures.

                    Avi Loeb

“Technosignatures relate to signatures of advanced alien technologies similar to, or perhaps more sophisticated than, what we possess,” said Avi Loeb, Frank B. Baird Jr. Professor of Science at Harvard. “Such signatures might include industrial pollution of atmospheres, city lights, photovoltaic cells (solar panels), megastructures, or swarms of satellites.”

Put simply, the scientists at the Center for Astrophysics at Harvard and Smithsonian, and the University of Rochester, will look for exactly the same technosignatures that we produce.

It’s believed that other civilizations would probably use solar panels to produce energy, and also probably pollute their planet’s atmosphere with artificial chemicals and gases.

How and why to find solar panels around distant planets

How does an astronomer look for sunlight reflected off solar panels around a distant exoplanet? As long as they know the wavelength band to search in—which is what this study will try to establish—astronomers training their telescopes on exoplanets may be able to spot these technosignatures.
Any alien civilisation is bound to have thought of solar power generation, think the scientists. “There are only so many forms of energy in the Universe,” said Adam Frank, a professor of physics and astronomy at the University of Rochester, and the primary recipient of the grant. “Aliens are not magic.”
