New Technique for Tracking Exoplanets Could Help in Search for Habitable Regions of the Universe

July 22, 2020                                  (rt.com)

• There are hundreds of ‘lost planets’ in distant solar systems. The usual method of tracking an exoplanet is to train the telescope on the star and then wait for a dip in brightness to indicating an object (i.e.: a planet) passing in front of the star in its orbit around the star. The telescope will then follow the planet’s trajectory until it disappears behind the star. It is then ‘lost’.

• Astronomers at the University of Warwick (in Coventry, England) have added an additional way of tracking these exoplanets, in order to ‘rediscover’ them. They track the planet’s orbit from their telescope, but they also track it from another telescope elsewhere on Earth. This allows astronomers to determine its speed and orbital trajectory around the back of the star, and to determine its temperature based on its proximity to the star. Once they know the planet’s orbit, they can gauge when it will reappear on the other side of the star in its continuing orbit.

• For example, the exoplanet known as NGTS-11b orbits a star 620 light-years away. The planet has the size and mass of Saturn and an orbit of 35 days, which makes it relatively close to its star. According to Dr. Samuel Gill at the University of Warwick, “Longer (orbital) period planets are cooler, more like the planets in our own solar system.” But with its relatively short 35 day orbit, NGTS-11b is close to its star and therefore quite hot – 320 degrees Fahrenheit. But it is still cooler than the planet Mercury. So it is close, but not within the ‘Goldilocks Zone’ where a planet may have liquid water and be able to harbor life (as we know it).

• The findings open up a new world of potential planets within the ‘Goldilocks zone’ of a far distant solar system that could potentially harbor extraterrestrial life.

 

The rediscovery of a planet lost in outer space could signal the beginning of tracking a habitable world in the ‘Goldilocks zone’ of a far distant solar system.

                      Dr. Samuel Gill

The planet is one of hundreds of ‘lost’ planets discovered by astronomers from the University of Warwick, and was the result of a new way of tracking and logging planets in hopes of finding something similar to our own.

Some of these lost planets reside in the Goldilocks zone – a particular range of orbits that allow the existence of liquid on a planet’s surface: too close to the sun and it will be too hot, too far away, too cold.

To accomplish the research, the team adapted the usual transit method of tracking a planet, in which the telescope waits for a dip in light that indicates that there is an object passing between the telescope and a star. It then follows the planet’s trajectory for 27 days before it disappears.

In this instance, however, the team followed the planet and further tracked it from a different station, allowing them to assess its speed and therefore orbit.

Six Billion Earth-Like Planets Could Exist in Galaxy

Article by Sean Martin                                June 17, 2020                                (express.co.uk)

• Searching through data from NASA’s planet hunting telescope Kepler, scientists from the University of British Columbia published a study in The Astronomical Journal estimating the likelihood of rocky Earth-like worlds which could contain water, within the Milky Way galaxy. A planet must also orbit a G-type star, like our Sun, and be positioned within the ‘Goldilocks Zone’ – the region around a star where it is neither too hot nor too cold – for life to exist.

• Astronomer Jaymie Matthews says, “Our Milky Way has as many as 400 billion stars, with seven per cent of them being G-type. So approximately six billion stars may have Earth-like planets in our Galaxy.” Researcher and co-author Michelle Kunimoto uses a technique known as ‘forward modelling’. “I started by simulating the full population of exoplanets around the stars Kepler searched. I marked each planet as ‘detected’ or ‘missed’ depending on how likely it was my planet search algorithm would have found them. Then, I compared the detected planets to my actual catalog of planets. If the simulation produced a close match, then the initial population was likely a good representation of the actual population of planets orbiting those stars.”

• Kunimoto also limits the possible number of habitable exoplanets where there exists a “radius gap”, “[I]t is uncommon for planets with orbital periods [of] less than 100 days to have a size between 1.5 and two times that of Earth,” says Kunimoto. “My calculations place an upper limit of 0.18 Earth-like planets per G-type star.” Previous estimates have suggested that there could be as few as 0.02 Earth-like planets per Sun-like star.

There are as many as 400 billion stars in the Milky Way galaxy alone, meaning there could be trillions of planets. As is evident from our solar system, the majority of these planets would be lifeless and barren, but billions could still be hospitable for life, according to new research. Scientists from the University of British Columbia (UBC) have searched through data from NASA’s planet hunting telescope Kepler to determine the likelihood of Earth-like planets – rocky worlds which could contain water.

To be considered Earth-like, the planet must also orbit a star like our Sun, known as a G-type star, according to the research published in The Astronomical Journal.

It also has to orbit the star in what is known as the Goldilocks Zone – the region around a star where it is neither too hot nor too cold for life to exist.
UBC researcher Michelle Kunimoto, co-author of the new study, said: “My calculations place an upper limit of 0.18 Earth-like planets per G-type star

“Estimating how common different kinds of planets are around different stars can provide important constraints on planet formation and evolution theories, and help optimise future missions dedicated to finding exoplanets”.

UBC astronomer Jaymie Matthews: “Our Milky Way has as many as 400 billion stars, with seven per cent of them being G-type.
“That means less than six billion stars may have Earth-like planets in our Galaxy.”

Are Humans a Genetic Accident?

Listen to “E81 8-30-19 Are-Humans-a-Genetic-Accident?” on Spreaker.

• Scientists have identified a group of planets outside our solar system where the same chemical conditions that may have led to life on Earth exist in what they call the Abiogenesis Zone. Would it contain life? Intelligent life? Human-like intelligent life?

• At some point the cosmos must have harbored extraterrestrial life, argues astrophysicist Adam Frank in a New York Times article “Yes, There Have Been Aliens”, Frank reasons that with an estimated 10 billion trillion habitable planets residing in boundless star system’s Goldilocks Zones, and considering that there are two planets in our own solar system – Earth and Mars – that we know have contained water and vegetation in its history, the degree of pessimism required to doubt the existence of another advanced extraterrestrial civilization existing at some point in time, borders on the irrational.

• On the other hand, there may have been only a handful of civilizations that have come and gone throughout a timeline of billions of years, decreasing the odds of two of them running into one another. How long does a civilization typically exist? It took the human race 7 million years to get far enough just to build a radio. Adam Frank points out that we haven’t the slightest clue how life arose on this planet, and what series of happenstance allowed primordial ooze to evolve into an intelligent being. Who knows what sort of life might be spawned on a different planet under different circumstances? The development of life is quite an unreliable process which further decreases the odds of our finding another civilization.

• Colin Blakemore, a neurobiologist at Oxford University, estimates that 200,000 years ago the brains of some, but not all, of an ancient primate species mutated into an intelligent human species. As it is unknown how this could have happened, it appears that humanity is a genetic accident. Then suddenly, over mere hundreds of years, we’ve recently develop the technological means to destroy ourselves. Perhaps, as Harvard’s Avi Loeb hypothesized in his book: How to Search for Dead Cosmic Civilizations, the explanation to Fermi’s paradox as to ‘where are all of the aliens?’ , is – from a cosmic perspective of billions of years – that they have all run the course of their brief existences.

• Paul Rimmer, an astrophysicist at Cambridge University, is pessimistic that life might exist outside of our own world. “You want to at least look at the places where the (building blocks of life) exist,” says Rimmer. “But they may not be sufficient. It’s possible you could mix them for billions of years and nothing happens.” Rimmer speculates that life itself may have come as one big accident. If so, then we are probably the only intelligent life in the universe, and maybe the only life at all. But this seems highly unlikely.

[Editor’s Note]   Oh how the world yearns for the truth about how we humans came to this point. These academics and scientists, coming from Deep State institutions such as Oxford, Cambridge and Harvard, must adhere to the Rockefeller Deep State presumption that as hard as we’ve tried, we have yet to find any evidence of extraterrestrial life. This is to ignore and obfuscate the multitude of evidence all around us – from ancient rock and renaissance paintings of ETs and UFOs, to modern testimony of ET and UFO sightings and personal experiences, to leaks of classified government documents, to consistent reports by credible insiders that various extraterrestrial species have been working behind the scenes with the Deep State government and the covert development of various secret space programs over the past eighty years. When these mainstream “experts” are finally unshackled from the Deep State-controlled narrative, they will relearn a history that answers all of their questions.

The universe, our galaxy, and our local star cluster of 52 stars is teeming with intelligent and highly advanced extraterrestrial civilizations. In fact, we Earth humans here in third density consciousness are at the bottom of the developmental totem pole. The fossil records suggest that we suddenly appeared here on Earth because, well, we suddenly appeared here on Earth. Human-like species of a wide variety of races happen to dominate this region of our galaxy. For millions of years, Earth was used as a haven for some of these third density races to escape catastrophes or wars on their home planets. For hundreds of thousands of years, technologically advanced extraterrestrials conducted genetic experiments on these different human-like species to create a congruent human species made up of various races, genetically and physiologically adapted to this particular planet. Higher density beings sat back to allow the Earth humans to develop uninhibited, while technologically advanced negative beings did their best to infiltrate and control the planet.

Some of these refugees came here upon the destruction of their Super Earth home which blew up and became the asteroid belt about a half million years ago. It left nearby Mars a barren husk of what it once was. About 55,000 year ago they resettled on Atlantis, an island that was and is part of the Antarctica continent. Then they set out to conquer the planet, evolving from the Pharaoh priest class into the “church and crown” medieval rulers, and then into the modern Illuminati cabal. This bloodline of the “Sons of Belial” worked with the advanced negative extraterrestrials over millennia to fully control the planet. But we now happen to be at the precise point in our species’ history when a solar energy event will cause the planet, and those humans on the planet who are prepared, to ascend to a fourth density of consciousness, and take our place among our human star cousins. This will extract us from the control of the dark ET/cabal alliance. The dark forces want to maintain the status quo and prevent this shift in consciousness by keeping the human population ignorant of the truth. They do this through their official control over the mainstream narrative which denies that extraterrestrial life exists beyond this small planet, and propagating articles such as this one.

 

Insights from the world’s leading scientists on evolution, climate change, technology and extraterrestrial life. We are the only species of the billions of species that have existed on Earth that has shown an aptitude for radios and even we failed to build one during the first 99% of our 7 million year history, says Australia National University’s Charley Lineweaver.

Are Homo sapiens a one-off, genetic accident?

chemical conditions that may have led to life on Earth exist in what they call the Abiogenesis Zone. It’s also possible that if there is extraterrestrial life, that it has, or will, develop in a totally different way than it did on Earth.

“I’m not sure how contingent life is, but given that we only have one example so far, it makes sense to look for places that are most like us,” said Cambridge University astrochemist, Paul Rimmer. “There’s an important distinction between what is necessary and what is sufficient. The building blocks are necessary, but they may not be sufficient, it’s possible you could mix them for billions of years and nothing happens. But you want to at least look at the places where the necessary things exist.

Rimmer speculates that life may have come from non-life as one big accident. This seems highly unlikely, at least given the way our universe is set up, so if it’s that way, then we are probably the only intelligent life in the universe, maybe the only life at all.

For what purpose did the human brain evolve?

“For what purpose did the human brain evolve?” It is a question that has puzzled scientists for decades, and was answered in 2010 by Colin Blakemore, an Oxford University neurobiologist who argued that a mutation in the brain of a single human being 200,000 years ago turned intellectually able primates into a super-intelligent species that would conquer the world. Homo sapiens appears to be genetic accident. Or are we?
