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.

This is How NASA Should Hunt Space For Aliens and UFOs

by Sebastian Kettley                  October 15, 2018                     (express.co.uk)

• Seventeen scientists representing the U.S. National Academies of Sciences, Engineering, and Medicine (NASEM) have released a report urging NASA to focus all future missions on the hunt for astrobiological alien life. The report was mandated by the U.S. Congress.

• The report argues that growing public interest in life outside of Earth will dictate the course of NASA’s research in the “coming decade”. The report reads: “In the three years since publication of NASA’s Astrobiology Strategy 2015, significant scientific, technological and programmatic advances in the quest for life beyond earth have taken place.” “Scientific advances have revolutionised fields of astrobiological study, ranging from results from missions focused on exoplanets, such as Kepler, to continuing discovery from existing planetary missions.”

• NASA’s astrobiologists have primarily looked at candidates for life in the solar system so far, such as Mars and the moons of Jupiter and Saturn. In recent years, NASA has found evidence of complex organic molecules in Martian rock, water plumes Saturn’s moon Enceladus and even icy deposits of water on our Moon. But an ever-growing list of exoplanets discovered far out beyond the borders of our corner of space have expanded the potential number of worlds where life could exist.

• Scientists are now hoping to unravel the mysteries of how life begins in the first place and whether these exoplanets have the right conditions for live to thrive. “Evidence from major transitions in environmental conditions from early Earth to today, and an understanding of how they occurred, is critical for the search for life.”

• The new report comes in contrast to NASA’s recent efforts to hunt the universe for signs of alien technosignatures – artificially created evidence of life in space such as radio signals – as opposed to biosignatures.

 

NASA should focus all future missions on the hunt for astrobiological alien life, top scientists have urged in a new report.

Seventeen scientists representing the US National Academies of Sciences, Engineering, and Medicine (NASEM) believe the hunt for alien life is paramount.

In a report mandated by the US Congress, the 17 experts claimed astrobiology needs to be at the forefront of NASA’s research in space.

The scientists labelled astrobiology a “field of rapid change” where technological and scientific progress is advancing the quest to discover alien life.

Their report reads: “In the three years since publication of NASA’s Astrobiology Strategy 2015, significant scientific, technological and programmatic advances in the quest for life beyond earth have taken place.

“Scientific advances have revolutionised fields of astrobiological study, ranging from results from missions focused on exoplanets, such as Kepler, to continuing discovery from existing planetary missions.”

The report further argued growing public interest in astrobiology and life outside of Earth will dictate the course of NASA’s research in the “coming decade”.

Astrobiology is the study of the origins, development and spread of life throughout the universe.

If Universe is Ocean, Humans Have Searched For Aliens in Swimming Pool, Claims New Study

by Nirmal Narayanan                  October 10, 2018                   (ibtimes.sg)

• The Italian/American physicist, Enrico Fermi, famously asked, if there are millions of galaxies and stars out there in the deep space, why humans have not met any advanced intelligent alien forms until now?

• ‘It is idiotic to conclude intelligent aliens do not exist nearby just because humans haven’t found them,’ said SETI astronomer Jill Tarter.

• Scientists haven’t found any intelligent extraterrestrials yet just because we have not started looking for them vigorously. A new study conducted by researchers at Pennsylvania State University has revealed that humans have searched just 0.00000000000000058% of the universe to find potential alien signals. In other words, if the universe was an ocean, humans have searched for aliens in barely a swimming pool’s worth of water.

• For its part, NASA recently revealed that it is working to locate alien civilizations by examining “Technosignatures” of life, including laser emissions, Dyson spheres and heat signatures in deep space.

 

A new study conducted by researchers at Pennsylvania State University has revealed that humans have searched just 0.00000000000000058% of the universe to find potential alien signals. In layman’s language, if the universe is an ocean, humans have searched for aliens in barely a swimming pool’s worth of water.

The study, published in the journal arXiv, could have also found the solution to the billion dollar Fermi paradox, which states if there are millions of galaxies and stars out there in the deep space, why humans have not met any advanced intelligent alien forms until now.

The study reveals that scientists haven’t found any intelligent extraterrestrials yet just because we have not started looking for them vigorously. Researchers who took part in the study believe that aliens, somewhere in that ocean of space might be signaling their existence, but until now, we have not looked into that deep corner.

“Suppose I tell you there’s a cool thing happening in Houston right now. I do not tell you where it is. I do not tell you when it is happening. I do not tell you what it is. Is it in a bookstore? Is it a music concert? I give you absolutely no priors. It would be a difficult thing to try and find it. Houston, we have a problem. We do not know what we’re looking for … and we don’t know where to start,” said Shubham Kanodia, a graduate student in astronomy who co-wrote the study at a NASA workshop on Technosignatures.
