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

• 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.

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.”

Does E.T. Exist? Possibly. A UVA Astronomer Weighs In.

Listen to “E75 8-23-19 Does E.T. Exist? Possibly. A UVA Astronomer Weighs In.” on Spreaker.
Article by Fariss Samarrai                      August 14, 2019                        (news.virginia.edu)

Scientific American interviewed University of Virginia astronomer Professor Kelsey Johnson (pictured above) on her personal opinions of the existence of extraterrestrial life, which was published in UVA Today. Here are some paraphrased excerpts from this interview:

• As a scientist, I have to acknowledge that ET life could have visited Earth. Some of the unresolved cases could be genuine, such as the “Lakenheath-Bentwaters Incident” in 1956 where radar tracked, and military aircraft chased, bright glowing objects over southeastern England. It was witnessed by both the US Air Force and Royal Air Force, so it cannot be summarily dismissed. But “just because we don’t know what it was, doesn’t mean that it was ET life.”

• Galactic travel distance and modern speed restrictions shouldn’t prevent us from assuming that technology could develop to allow humans to travel to distant star systems. We went from the first airplane to space travel in only fifty years. But if we developed a way to travel at 1/100th the speed of light, which is 500 times faster than anything we currently have, it would still take over 400 years to reach Proxima Centauri, which is the nearest star. But a 400 year span of time might not be as daunting to ET lifeforms that could live far longer lifespans than humans.

• Any ET life that could visit us is likely to be millions of years more advanced than we are. Why would they visit us? Perhaps they are benevolent and checking in to see how we’re doing. Or maybe we are a science experiment they are checking up on. I doubt their intentions are hostile, or we would already be obliterated.

• The human need to colonize beyond Earth seems to be hardwired into our collective behavior. If we survive as a species long enough to become technologically advanced, I would be shocked if we don’t eventually visit other planets. This brings us to the core of Fermi’s Paradox. If humans would naturally spread out into colonizing the galaxy, why don’t we see other advanced civilizations doing so? The depressing answer is that any civilization that becomes sufficiently technologically advanced is doomed to destroy itself. But if we can survive our technological adolescence, I think that human creativity, bravery, and perseverance will compel us to journey to far-flung places in the galaxy.

• As far as we know now, we are the only species in the universe capable of trying to understand this grand cosmos. This gives us a set of ethical responsibilities – to not only survive, but to take care of our planet, and each other, ourselves, and the universe.

[Editor’s Note]   Most of the time, we hear from scientists who insist that physics will never allow travel beyond the speed of light; or that there is a perfectly logical scientific explanation for the UFO phenomenon besides visiting extraterrestrials; or that, since humans could not survive intergalactic travel, then an alien civilization would be equally prohibited; or that if extraterrestrials did come to the Earth, they would exterminate us.

It is refreshing to hear from a mainstream scientist who allows for the possibility of the eventual development of advanced technologies that defy our known physics, or that an alien species’ physiology might be dramatically different than our own. Professor Johnson concedes the possibility that advanced ET civilizations could be capable of intergalactic travel and visit the Earth, even though her scientific credentials will not allow her to admit that this is indeed occurring. She even allows for the possibility that humanity itself could be a scientific experiment conducted by advanced extraterrestrial beings.

This is the fine line that today’s academics and scientists must walk: to think beyond the restrictive mainstream mindset while at the same time avoid being mocked and disparaged by their peers who pander to a Deep State that economically controls them and these academic and scientific institutions.

 

Many people have a knee-jerk reaction when it comes to extraterrestrial life. Claims of sightings often are immediately dismissed or ridiculed as being crazy. Alternately, some people assume that scientists or the government are hiding something. Thanks to Hollywood, and sometimes-irresponsible “documentaries,” many misconceptions exist regarding E.T. life – whether or not E.T. life actually exists.

University of Virginia astronomer Kelsey Johnson recently weighed in with a commentary for Scientific American. Here’s what she has to say for readers of UVA Today.

Q. There is a lengthy history of claimed sightings of UFOs and abductions of humans by aliens. Some ancient cave paintings seem to depict UFOs and aliens. Do you think it’s possible that we have been visited by aliens?

A. “Possible” is a loaded word from a scientific perspective. We don’t have any scientific evidence that E.T. life has not visited Earth, so sure, it is possible. But there are only a handful of investigated cases that don’t have other possible, and more plausible, explanations.

But those handful are highly intriguing. One particular open case that has caught people’s attention is a famous unresolved case from England in 1956 known as the “Lakenheath-Bentwaters Incident.” One of the reasons this incident garnered attention is that it was witnessed by both the U.S. Air Force and Royal Air Force. The official record includes both visual sightings of aerial phenomena and radar contact. Although it is tempting to jump to conclusions, just because we don’t know what it was, doesn’t mean that it was E.T. life.

Keeping an open mind is essential for scientific progress, but this progress also requires that claims can be either falsified or verified. Unfortunately, virtually none of E.T. life sightings come with a preponderance of testable evidence.
But as a scientist, I have to acknowledge that E.T. life could have visited Earth; some of the unresolved cases could be genuine, and we can’t rule that out.

Scientists Narrow Search After Shocking Find About Extraterrestrials

by Sean Martin                 June 11, 2019                  (express.co.uk)

• Scientists searching for habitable alien worlds usually focus on the ‘habitable zone’, where the region of space is neither too cold nor too warm for life to exist. Star gazers at the University of California Riverside believe that scientists have failed to take into account a build-up of toxic gasses within a planet’s atmosphere which would not allow complex life to evolve.

• For example, any planet on the coldest outer edge of the habitable zone with liquid on the surface would require carbon dioxide at levels thousands of times that of Earth’s to maintain liquid and not have it freeze, according to Edward Schwieterman, lead author of a study published in The Astrophysical Journal. “That’s far beyond the levels known to be toxic to human and animal life on Earth,” said Schwieterman.

• Another inhospitable example  is intense ultraviolet radiation as from the Earth’s two closest alien stars – Proxima Centauri and TRAPPIST-1, which would batter any planets within their habitable zones, leading to a build up of poisonous carbon monoxide.

• “This is the first time the physiological limits of life on Earth have been considered to predict the distribution of complex life elsewhere in the universe,” says Timothy Lyons, one of the study’s co-authors and a professor of biogeochemistry in UCR’s Department of Earth and Planetary Sciences, and director of the Alternative Earths Astrobiology Center.

• “As far as we know, Earth is the only planet in the universe that can sustain human life,” concludes Schwieterman.

[Editor’s Note]    I’m sure that there are alien civilizations out there who consider this planet to be blanketed in a “poisonous” gas – oxygen. How can educated ‘experts’ make such ludicrous statements as “Earth is the only planet in the universe that can sustain human life”? Human-type beings exist throughout not only the universe, but throughout the galaxy and our own star system of 52 stars. This is just more disinformation calculated to make the public falsely believe that there is no alien presence on our world, or even close by. Lately, in the press there seems to be a concerted effort to push this Deep State agenda of ‘keep moving, there’s nothing to see here’.

 

Scientists’ search for aliens has become more focused on a smaller number of planets after making a discovery about the composition of most planets’ atmospheres. Typically, alien hunting experts have been analysing planets which are in the habitable zone of their host star – an region in space where it is neither too cold nor too warm for life to exist.

However, experts from the University of California Riverside (UCR) believe other scientists have failed to take into account a build up of toxic gasses within a planet’s atmosphere which would not allow complex life to evolve.
For example, by using computer models the researchers found that any planet on the outer edge of the habitable zone with liquid on the surface would require carbon dioxide – a greenhouse gas – levels thousands of times that of Earth’s to maintain liquid and not have it freeze.

Edward Schwieterman, lead author of the study published in The Astrophysical Journal, and a NASA Postdoctoral Program, said: “To sustain liquid water at the outer edge of the conventional habitable zone, a planet would need tens of thousands of times more carbon dioxide than Earth has today.

“That’s far beyond the levels known to be toxic to human and animal life on Earth.”
