• The $100 million 10-year project funded by Russian billionaire Yuri Milner, called the  “Breakthrough Listen” project, is the most extensive SETI (Search for Extraterrestrial Intelligence) program in history. The project, which began in 2015, has surveyed over 1,000 stars within 160 light-years away from Earth for signs of alien radio signals, with no positive results.

• ‘Breakthrough Listen’ announced that its team will begin looking for new signs of alien technology using the Very Energetic Radiation Imaging Telescope Array System (VERITAS), consisting of four 12-meter optical telescopes at the Fred Lawrence Whipple Observatory in Amado, Arizona. Using VERITAS, astronomers will begin scanning the night sky for nanosecond flashes of light, known as “fast optical pulses”, from nearby stars indicating a new class of alien communication. Said Andrew Siemion, director of Berkeley’s SETI Research Center, “Optical communication has already been used by NASA to transmit high-definition images to Earth from the moon, so there’s a reason to believe that an advanced civilization might use a scaled-up version of this technology for interstellar communication.”

• VERITAS searched for such laser pulses from the mysteriously dimming Tabby’s Star after some speculated there could be an alien megastructure surrounding it. If Tabby’s Star pointed powerful lasers at the Earth, VERITAS could detect them. Less powerful lasers could be detected from closer star systems. David Williams, a member of the VERITAS and professor of physics at the University of California, Santa Cruz, said, “It is impressive how well-suited the VERITAS telescopes are for this project, since they were built only with the purpose of studying very-high-energy gamma rays…”.

• At the VERITAS initiative’s launch, physicist Stephen Hawking said, “[I]n an infinite universe, there must be other occurrences of life… [P]erhaps intelligent life might be watching these lights of ours… Or do our lights wander a lifeless cosmos, unseen beacons announcing that, here on one rock, the universe discovered its existence?”

• SETI’s Russian benefactor, Yuri Milner says, “[O]ur philosophy is to look in as many places, and in as many ways, as we can. VERITAS expands our range of observation even further.”

[Editor’s Note]    SETI is now using a $100 million telescope array to search for lights and lasers emanating from extraterrestrial sources in the cosmos. So much money is being wasted on this Deep State disinformation program which is only meant to make the public believe that if there were any extraterrestrial beings and civilizations to be found, such equipment could not miss them, when in reality the extraterrestrial presence is all around us. Of course the Breakthrough Listen project will fail because the Deep State’s true agenda is to deny the existence of extraterrestrials. Or will it be used by the Deep State to claim success and control the narrative through a new disinformation campaign when the exposure of the extraterrestrial presence becomes imminent?

 

Are aliens using super powerful flashlights to get our attention? Astronomers think there’s a chance they are.
Since the invention of the radio, humans have been silently listening to the stars, wondering if we are alone in the universe. But if intelligent alien life does exist, the extraterrestrials could be using other forms of technology to communicate. Astronomers are beginning to not only listen to the cosmos but also gaze toward it for other signs of alien tech: laser beams.

Breakthrough Listen, the most extensive Search for Extraterrestrial Intelligence (SETI) program in history, announced that its team will begin looking for new signs of alien technology using the Very Energetic Radiation Imaging Telescope Array System (VERITAS) at the Fred Lawrence Whipple Observatory in Amado, Arizona.

“When it comes to intelligent life beyond Earth, we don’t know where it exists or how it communicates,” Yuri Milner, billionaire particle physicist and founder of Breakthrough Listen, said in a statement. “So our philosophy is to look in as many places, and in as many ways, as we can. VERITAS expands our range of observation even further.”

Using VERITAS, astronomers will begin scanning the night sky for nanosecond flashes of light from nearby stars. Like a lighthouse beacon for the cosmos, these brief pulses of optical light would outshine any nearby stars and could indicate a method of alien communication.

What Is a Dyson Sphere?

Listen to “E65 8-12-19 What Is a Dyson Sphere?” on Spreaker.

Article by Adam Mann                       August 1, 2019                     (space.com)

• In 1960, British-American theoretical physicist Freeman Dyson theorized that as an intelligent alien species’ population increased by 1% per year, their energy needs would grow exponentially becoming a trillion times larger in just 3,000 years. After developing and saturating the local moons and planets in their solar system, they may embark on a longer-term solution: The Dyson sphere.

• A Dyson sphere is a structure with platforms orbiting in tight formation that surrounds and encloses a larger celestial body, such as a gas giant planet like Jupiter or the system’s star itself, like a shell. Such an artificial structure would offer plenty of living space and energy production, drawing from the gas planet or star’s radiation. But as the Dyson sphere absorbed radiation, thereby dimming the planet from an outside observer’s perspective, Dyson theorized that the structure would need to re-radiate this energy through infrared wavelengths to avoid melting the structure itself. Therefore, a Dyson sphere would emit a bright signature in the infrared spectrum while being invisible to the human eye.

• This infrared radiation is considered a type of ‘technosignature’ that astronomers can use to detect an advanced civilization. Since the 1960’s, researchers have scanned infrared maps of the night sky in hopes of spotting a Dyson sphere, without success. But in 2015, Yale University astronomer Tabetha Boyajian did find a distant star that dimmed and flickered. Astronomers speculated that “Tabby’s Star” could be a partially built Dyson sphere. Because other astronomical experiments could not find other technosignatures from the star, scientists now think the object’s light patterns have some kind of non-alien explanation.

• In 1937, Olaf Stapledon first described a “gauze of light traps” surrounding a star system to utilize its solar energy in his novel “Star Maker”. Freeman Dyson acknowledged that this sparked his concept of a Dyson sphere. In 1992, a Dyson sphere was depicted in an episode of “Star Trek: The Next Generation”.

 

A Dyson sphere is a theoretical mega-engineering project that encircles a star with platforms orbiting in tight formation. It is the ultimate solution for living space and energy production, providing its creators ample surface area for habitation and the ability to capture every bit of solar radiation emanating from their central star.

Why build a Dyson sphere?

          Freeman Dyson

Why would anyone construct such a bizarre monstrosity? According to British-American theoretical physicist Freeman Dyson, who first speculated about these putative structures in 1960, an intelligent alien species might consider the undertaking after settling on some moons and planets in their local stellar neighborhood. As their population increased, these extraterrestrials would start to consume ever-greater amounts of energy.

Assuming this alien society’s populace and industry grew at a modest 1% per year, Dyson’s calculations suggested that the aliens’ area and energy needs would grow exponentially, becoming a trillion times larger in just 3,000 years. Should their solar system contain a Jupiter-size body, the species’ engineers could try to figure out how to take the planet apart and spread its mass in a spherical shell.

              Tabetha Boyajian

By building structures at twice the Earth-sun distance, the material would be sufficient to construct a huge number of orbiting platforms 6 to 10 feet (2 to 3 meters) thick, allowing the aliens to live on their star-facing surface. “A shell of this thickness could be made comfortably habitable, and could contain all the machinery required for exploiting the solar radiation falling onto it from the inside,” Dyson wrote.

But after absorbing and exploiting the solar energy, the structure would eventually have to reradiate the energy or else it would build up, causing the sphere to eventually melt, according to Dyson. This means that, to a distant observer, the light of a star wrapped in a Dyson sphere might appear dimmed or even entirely darkened — depending on how dense the orbiting platforms were — while glowing curiously bright in infrared wavelengths that aren’t visible to the naked eye.

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.
