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.”

“The Search for Techno-Artifacts” From an Earlier Civilization in the Solar System

May 2, 2020                             (dailygalaxy.com)

• In his 2016 study, ‘Prior Indigenous Technological Species’, Penn State’s Jason Wright discussed possible origins and locations for “technosignatures” of a technological species’ civilization that could have existed in the solar system prior to humanity’s rise on Earth, or on nearby planets Venus and Mars. “From a purely scientific standpoint, it’s a perfectly reasonable question to ask whether life may have existed elsewhere in the Solar System, or does today,” said Wright, who is also a member of the ‘Center for Exoplanets and Habitable Worlds’ at Penn State.

• What could have ended a prior technologically advanced civilization within our solar system? “The most obvious answer is a cataclysm, whether a natural event, such as an extinction-level asteroid impact or self-inflicted, such as a global climate catastrophe,” says Wright. “[S]uch an event would only permanently extinguish the species if there were many cataclysms across the solar system closely spaced in time, (such as) a swarm of comets or interplanetary warfare, …an unexpected nearby gamma ray burst or supernova…”

• In the case of Venus, its global greenhouse and resurfacing might have erased all evidence of a prior civilization’s existence on the Venusian surface. In the case of Earth, erosion and plate tectonics may have erased most of such evidence if the species lived a billion years ago. Remaining indigenous technosignatures would be extremely old, limiting the places they might still be found to beneath the surfaces of Mars and the Moon, or in the outer solar system.

• In a 2019 study co-written by Manasvi Lingam (at Florida Tech) and Harvard astrophysicist Avi Loeb entitled, “The Moon as a Fishing Net for Extraterrestrial Life”, Loeb suggested that Earth’s Moon might yield traces of technological equipment that crashed on the lunar surface a billion years ago. “The absence of a lunar atmosphere,” wrote Loeb, “guarantees that these messengers would reach the lunar surface without burning up. In addition, the geological inactivity of the Moon implies that the record deposited on its surface will be preserved and not mixed with the deep lunar interior. Serving as a natural mailbox, the lunar surface collected all impacting objects during the past few billions of years. Most of this “mail” comes from within the solar system.”

 

         Jason Wright

One of the primary open questions of astrobiology is whether there is extant or extinct life elsewhere the Solar System. Astrophysicists Avi Loeb at Harvard and Penn State’s Jason Wright have both explored the question, with Loeb suggesting that ancient technological artifacts from beyond the Solar System may exist on Earth’s Moon amounting to a letter from an alien civilization saying, “We exist.”

Wright, a member of the Center for Exoplanets and Habitable Worlds, has considered the possibility that a technological

species could have existed in the Solar System prior to humanity’s rise on Earth in his study, Prior Indigenous Technological Species.

In 2016, Wright authored a paper that discussed possible origins and locations for “technosignatures” of such a civilization while other astronomers have suggested looking for lights on Kuiper Belt Objects that “may serve as a lamppost which signals the existence of extraterrestrial technologies and thus civilizations.”

The origins and possible locations for technosignatures of such a prior indigenous technological species might have arisen on ancient Earth or another body, such as a pre-greenhouse Venus or a wet Mars. In the case of Venus, the arrival of its global greenhouse and potential resurfacing might have erased all evidence of its existence on the Venusian surface. In the case of Earth, erosion and, ultimately, plate tectonics may have erased most such evidence if the species lived a billion years ago. Remaining indigenous technosignatures, observes Wright, might be expected to be extremely old, limiting the places they might still be found to beneath the surfaces of Mars and the Moon, or in the outer Solar System.

Scientists Wonder If Extraterrestrial Life Has Visited Earth

Listen to “E142 10-26-19 Scientists Wonder If Extraterrestrial Life Has Visited Earth” on Spreaker.

Article by Albert McKeon                      October 15, 2019                       (northropgrumman.com)

• When people think of UFOs, they typically think of craft flying over their heads. No one talks much about the possibility that intelligent extraterrestrials may already be here among us on Earth. Last year, after writing a paper on theoretical ways for SETI to detect an alien presence, NASA physicist Silvano Colombano was accused by Fox News of claiming that aliens have indeed come to Earth. Colombano was quick to correct the Fox News story, saying that he believes an alien visit is only theoretically possible. However, Colombano also stated that “reports of unidentified aerial phenomena should be the object of serious study.” But mainstream scientists are loath to even discuss an extraterrestrial presence, much less study it.

• So the discussion about UFOs and extraterrestrials has been relegated to ‘claims’ and ‘theories’. Claims such as a New Hampshire couple being abducted by aliens one summer evening in 1961; or theories such as Harvard Professor Avi Loeb assertion that the rogue “asteroid” Omuhamuha may have been an alien probe, which “elicited some derision from scientists.”

• The vast majority of our efforts to discover intelligent extraterrestrials has been by looking out beyond our planet. The ‘Search for Extra-Terrestrial Intelligence’ or ‘SETI’ employs more than 130 scientists, educators and administrative staff in a quest to “explore, understand, and explain the origin and nature of life in the universe and the evolution of intelligence.” They do this by monitoring telescope arrays that study the characteristics of red dwarf stars and newly-discovered exoplanets. Unfortunately, SETI has recently had to cross a large number of potential exoplanets off of their list for having “unsuitable environments”.

[Editor’s Note]   So this is where the line is currently drawn. The compromised media welcomes any news on a ‘scientific research group’ like SETI (also compromised) searching for life on other planets, but they will attack you as soon as you suggest that the aliens are already here. Organizations such as Fox News and SETI only exist to do the Deep State’s bidding, which in this case is to make it sound like smart people are doing everything possible to find other extraterrestrial life or even a viable explanation for UFOs, but alien civilizations beyond the Earth simply do not exist. They have most of the world believing this. The Deep State and the elite they protect does not want people to know that they have been fleecing the natural and economic resources of the Earth and its inhabitants for the past seventy years in order to develop advanced technologies and create a secret space program to rival the other space programs, both human and extraterrestrial, that exist all around us and throughout the galaxy. And they will stop at nothing to prevent the population from “waking up” to this reality.

 

Of course, whether extraterrestrial life has actually touched the soil of Earth — or floated above it, observing us all — has been a burning question for almost as long as humankind could look at the stars. The many claims of alien sightings, often buttressed by grainy photos of UFOs, and the many theories about outer space creatures already living among us could fill enough books to weigh down a spacecraft that’s collecting samples of our planet.
One thing is for certain: The public and private agencies that deal with all things space focus on finding life away from Earth. They are not researching, at least publicly, the scientific possibility of whether aliens have already been on our planet. For that matter, governments answer stories of UFO sightings on Earth by pointing to the weather or by saying the claim couldn’t be corroborated. There are no official records of aliens visiting Earth.

Claims and Theories of Aliens Visiting Earth

Discussion about aliens on Earth can be, for the sake of argument, placed into two camps: claims and theories. Claims are those that appear on the covers of supermarket tabloids or occasionally make for a fun feature in a mainstream news publication. For instance, a New Hampshire couple that spoke of being captured by aliens on a late-summer evening in 1961 as they drove through the White Mountains is the first widely-publicized alien abduction claim, a tale that started a legion of others.

Theories of alien visits can also spread like wildfire in the mainstream news if they are made by someone with authority. It happened only recently. Avi Loeb, the chair of Harvard University’s astronomy department, didn’t propose that aliens were even close to Earth. Rather, he and a colleague posited that Oumuamua, a cigar-shaped comet or object that whizzed by the sun in 2017, might have been a probe sent to the vicinity of Earth by an alien civilization. The theory, published in The Astrophysical Journal Letters, elicited some derision from scientists.

      Silvano Colombano

The minor controversy led NASA physicist Silvano Colombano to say that scientists essentially rock the establishment when they theorize about extraterrestrial life. “General avoidance of the subject by the scientific community” creates a catch-22, Colombano told Quartz. He means that scientists might appear crazy for posing questions about aliens, but society will never know about alien life or any possible alien missions to Earth if no one in the scientific community examines the concept.

Colombano himself got caught up in the debate last year, when Fox News reported he claimed aliens have indeed come to Earth, pointing to a document of his on the space agency’s website. But Colombano was quick to correct the Fox News story, saying it was taken out of context and that he believes an alien visit is only theoretically possible. “My perspective was simply that reports of unidentified aerial phenomena should be the object of serious study, even if the chance of identification of some alien technology is very small,” he told Live Science.
