Most Extensive Search Through Space Confirms We Are Alone

by Jessica Dunne                    June 19, 2019                       (10daily.com.au)

• The most comprehensive search for alien life to date has found we’re alone in the universe. For three years, the Breakthrough Listen project has searched 1,327 stars within an area covering 160 light years of Earth for signs of intelligent life. But the University of Berkeley researchers compare it to “searching for a needle in a haystack.” They came up with nothing.

• The Berkeley researchers used the Green Bank telescope in West Virginia and Australia’s Parkes telescope to find ‘technosignatures’ (i.e.: evidence of technologies) from other planets, while sifting through the plethora or signals coming from human technology on Earth.

• Tens of millions of signals were discarded through filtering techniques, and the team was then left with a handful of potential signatures that fit the bill. Researchers said that, “The few remaining technosignature candidates were carefully examined, and determined to be outlying examples of human-generated radio frequency interference that survived the two cuts.”

• But the team isn’t giving up hope of finding life out in the universe, says Breakthrough Listen Project scientist Dr. Danny Price. “We found no evidence of artificial signals from beyond Earth, but this doesn’t mean there isn’t intelligent life out there. We may just not have looked in the right place yet, or peered deep enough to detect faint signals.”

[Editor’s Note]   Once again, this “scientific” program plays right into the Deep State agenda of letting the public think that science is doing everything it can to find evidence of extraterrestrial civilizations. Does the fact that they’ve had no success prove that we humans are all alone in the universe? Or does it show that highly advanced extraterrestrials won’t be found so long as they don’t want to be found, and so long as the Deep State maintains its official government cover-up of a widespread extraterrestrial presence on and around our planet.

 

The most comprehensive search for alien life to date has found we’re alone in the universe, but scientists aren’t giving up hope.

Over a three-year period, the Breakthrough Listen project searched an area covering 1,327 stars within 160 light years of Earth for signs of intelligent life.

The University of Berkeley was behind the search for extraterrestrials, using the Green Bank telescope in West Virginia and Australia’s own Parkes telescope.

They said it was like “searching for a needle in a haystack”.

Researchers had to sift through the vast majority of signals coming from human technology to identify ‘technosignatures’.

“[Technosignatures are] evidence of technology (such as transmitters or propulsion devices) built by civilisations beyond Earth,” researchers said.

The first technique used looked for ‘narrow’ signatures that were too well-defined to come from natural sources.

A filter then removed signals that came from fixed points in the sky.

Researchers then compared scans of the area surrounding the star being targeted and removed signals not coming from that direction.

The Search for Extraterrestrial Intelligence Heats Up

by Dirk Schulze-Makuch                  March 11, 2019                    (airspacemag.com)

• A remarkable meeting occurred over the weekend of March 9-10 in Tutzing, Germany, just outside of Munich. Its theme: Are we alone in the Universe? Eminent German astrobiologists and scientists were invited to give presentations, including Karl Menten, Director of the Max Planck Institute, Gerhard Haerendel, recipient of the Allan D. Emil Memorial Award for pioneering achievements in space sciences, Andreas Losch from the Institute of Systematic Theology at the University of Bern, Switzerland, and the article’s author, Dirk Schulze-Makuch, who spoke on the Cosmic Zoo hypothesis.

• The meeting was hosted by the evangelical academy, underscoring the continuing interest of religious groups in the possibility of extraterrestrial life and what it might mean for faith communities. The Catholic Church appears to me to be the most interested group of all. In 2014 the Vatican Observatory even co-hosted a conference in Arizona on whether we are alone in the Universe.

• Earlier this year, the discovery of a new source of Fast Radio Bursts suggested that they could be messages from advanced technological civilizations. Tabby’s Star, which suddenly dips its light curve, has been linked to alien megastructures.

• Last November, Avi Loeb of Harvard University suggested that ‘Oumuamua’, the first object seen to enter our Solar System from interstellar space, could be a lightsail built by an advanced intelligent civilization. Its motion seems to indicate that something other than simple gravitation might be at work.

• The longest unresolved enigma is the Wow! signal, which has all the hallmarks of an alien transmission but unfortunately was only received once. It may have been a transmission from one starship to another, or perhaps from a ship to its home base, and Earth just happened to be in the way.

• However likely or unlikely these anomalies, it is clear that interest in the Search for Extraterrestrial Intelligence is on the rise again, as shown not only by this latest conference near Munich, but by NASA’s renewed interest in what’s now called “technosignatures” of advanced life. Many people, beyond just scientists, understand what a detection of extraterrestrial intelligent life elsewhere would mean – nothing less than a complete re-assessment of our place in the Universe.

 

A remarkable meeting occurred outside Munich, Germany this past weekend. Its theme: Are we alone in the Universe? The most eminent German-speaking scientists in the field of astrobiology were invited to give keynote presentations, which included talks by Karl Menten, Director of the Max Planck Institute for Radioastronomy, on the search for extraterrestrial intelligent life; by Gerhard Haerendel, recipient of the Allan D. Emil Memorial Award for pioneering achievements in space sciences, on messaging to extraterrestrial civilizations (METI); and by Andreas Losch from the Institute of Systematic Theology at the University of Bern, Switzerland, on the scientific, philosophical and theological consequences of the presence of extraterrestrial civilizations. I also gave a talk, on the possibility of complex life on other planets based on the Cosmic Zoo hypothesis.

The meeting was hosted by the evangelical academy in Tutzing, Germany, underscoring the continuing interest of religious groups in the possibility of extraterrestrial life and what it might mean for faith communities. The Catholic Church appears to me to be the most interested group of all. In recent years I’ve seen many of its representatives at scientific meetings. In 2014 the Vatican Observatory (yes, they have their own observatory) even co-hosted a conference in Arizona on whether we are alone in the Universe.

So, are we?

If you were to ask Avi Loeb of Harvard University, he would likely direct your attention to ‘Oumuamua, the first object seen to enter our Solar System from interstellar space. Last November Loeb pointed to six strange facts about ‘Oumuamua, suggesting that it could be an artificial object, possibly a lightsail built by an advanced intelligent civilization. Most puzzling of all is its shape: long, shiny and unusually thin for a rock. And its motion seems to indicate that something other than simple gravitation might be at work.

Alien ‘Artifacts’ Made By Civilizations From Mars or Venus Could Be Hidden On Earth, NASA Study Suggests

by Jasper Hamill                     December 26, 2018                     (metro.co.uk)

• Dozens of NASA space scientists teamed up to explore how our species could detect ‘technosignatures’, ie: the name for pieces of evidence which give away the presence of advanced alien civilizations – radio waves are detected coming from a distant star system, or Dyson Sphere ‘megastructure’ power stations surrounding a star in order to harvest its’ energy, for example.

A November 28, 2018 NASA report entitled “NASA and the Search for Technosignatures” suggests that the truth about extraterrestrials could be lurking right under our noses. In a new report, scientists suggest that our own planet may be hiding alien ‘artifacts’, some of which may even have been built by extinct civilizations who lived on Mars, Venus or even Earth.

• ‘Because the geological, paleontological, and archaeological records on Earth are so incomplete, it is even possible that the Earth itself hosts such (extraterrestrial) artifacts, although, again, this idea is often conflated with unscientific popular imaginings and science fiction stories about alien visitation, and so must be approached carefully,’ the NASA researchers wrote.

• The report continues, ‘If technosignatures were discovered in the solar system, it would be worth considering whether their origin might not be interstellar. Specifically, since the Earth is home to the only known species capable of interstellar communication and planetary travel (although both technologies remain in their early development), the Earth remains the only known planet fecund enough to promote technological life, and so it or an early, habitable Mars or Venus could even be the origin of such technology.’

• The NASA report noted that ‘Technosignatures in the solar system might come in the form of free-floating probes or structures—either passing through the solar system or in orbit around the Sun or other body—or in the form of structures or other signs of technologies on planetary surfaces.’

• So far, the only potential alien artifact we’ve seen has been ‘Oumuamua’, the first ‘interstellar visitor’ to be observed in our stellar neighborhood after traveling here in 2017 through deep space. Still, most scientists believe its origins are natural rather than artificial. Oumuamua changed direction as it passed the sun, which may have been caused by a natural process called outgassing – although there is a very slight chance this could have been the result of it being steered somehow.  (see previous ExoNews article on the Oumuamua visitor here)

 

You might think that humanity’s best chance of finding alien life involves peering deep into space and analysing faraway galaxies.

But a Nasa study has suggested the truth about extraterrestrials could be lurking right under our noses.

Dozens of space scientists have teamed up to explore how our species could detect ‘technosignatures’, the name for pieces of evidence which give away the presence of advanced alien civilisations.

Some of these tell-tale signs are obvious. For instance, if loads of radio waves are detected coming from a distant star system, then it could be a clue which shows it’s inhabited by intelligent extraterrestrial organisms.

We could also search for alien societies by looking for ‘megastructures’ called Dyson Spheres, which are theoretical power stations built surrounding a star to harvest its energy.

These would be easy to spot because they are likely to be gigantic and block out starlight whenever they pass in front of their sun.

Other technosignatures are harder to identify, such as evidence that a planet has been polluted by heavy industry.

In the new report, scientists also make the fascinating suggestion that our own planet may be hiding alien ‘artefacts’, some of which may even have been built by extinct civilisations which lived on Mars, Venus or even Earth.

‘Because the geological, paleontological, and archaeological records on Earth are so incomplete, it is even possible that the Earth itself hosts such artefacts, although, again, this idea is often conflated with unscientific popular imaginings and science fiction stories about alien visitation, and so must be approached carefully,’ researchers wrote.
