Amazing nightvision UFO footage – Florida, 2020
Amazing nightvision UFO footage – Florida, 2020
This footage was recorded in the sky above Florida a few days ago.

Antarctica is the planet's southernmost continent where the geographic South Pole is located and is home to some 1,000 scientists attempting to understand more about the history of Earth and the effects of climate change. However, one programme, known as the Antarctica Drilling Project (ANDRILL), took things one step further by drilling more than 400 feet into the ice sheet, exposing a shocking past. Their experiment was shown during NOVA’s “The Secrets of Antarctica” documentary, in which they hoped to uncover more about past periods of global warming and cooling.
The narrator revealed in 2015: “Unlike drilling through sea ice which is just 26 feet thick the ice shelf here is 400 feet at least.
“But that’s only the beginning, no one has ever drilled through an ice shelf and it presents a challenge because they float up and down with the tide so you’ve got to deal with vertical and sideways change.
“Eventually the drill pipe will get bent, to you need to drill through a thick layer of ice that is constantly moving without breaking.
“To confront this unique challenge, the ANDRILL team invents a new tool, a hot-water drill, this marvel of engineering is a moving ring of heat that blasts jets of steaming water to melt a wide hole so the drill can operate freely through 400 feet of shifting ice.
Antarctica scientists made a stunning discovery

Secrets of Antarctica
“Once again, time is so precious that the team must work around the clock, not only retrieving cores but also analysing them.”
The narrator went on to reveal the groundbreaking discovery made thanks to the revolutionary drill.
He added: “An 80 feet core dates back about three million years and is closely examined.
“It contains microfossils of single-celled animals known as forams.
“They are from the crucial warm period called the Pliocene and these tiny shells are precise indicators of ocean temperature.”
Dr Gavin Dunbar, from the Antarctic Research Centre, explained how the sample of forams may reveal a shock to Earth’s path.
He said in 2015:“These guys are about the size of a grain of sand and because the same species lived through time we can use the chemistry and molecule examples to calibrate the ancient examples.
“We can measure two metals, magnesium and calcium that are in the ocean that get incorporated into their shells.
“That process depends on the temperature of the ocean, so if we know those levels, we can determine the temperature of the ocean at the time that foram lived.
“What this is telling us is that temperatures were three to four, maybe even five degrees above present.”
Shockingly, the find may mean that Earth once suffered global warming levels considerably worse than what we see today.
However, more research needs to be done to confirm the results.
The ANDRILL project involves scientists from Germany, Italy, New Zealand, and the United States and is based at the McMurdo Station.
The $30million (£23million) programme has since achieved its operational goal of retrieving a core record of the last 17 million years, filling crucial gaps left by previous drilling projects.
It is now up to scientists to study each sample and come up for a future hypothesis.
They return every so often, especially when the weather grows cold and the media runs out of stuff to talk about, or the story runs afoul of a hungry editor starving for a juicy ration of paranormal ghoulishness.
The flaps of “cow mutilations” or cases involving “cattle mutilations” represent a branch phenomenon of popular ufology or the urge to find evidence of extraterrestrial activity on Earth. It is also kept alive, however, by other media-created mysteries, such as the Chupacabras, or it receives a dose of crafty explanations such as those built by conspiracy theorists (which should not be cast aside, despite their minimal diffusion, as these are often turned into successful sci-fi scripts).
On August 25 of this year, the La Nación newspaper published another news item. Last year another appeared in Tucumán, and if we keep searching, or google back even further, there isn’t a year that does not include a report on this mystery that proves hard to extinguish. Likewise, we find a more intensive presence in provinces such as Entre Rios, where local UFO groups – highly interested in the matter – publicize accounts that would otherwise go unnoticed.
In 2002, this phenomenon manifested itself in Argentina with unprecedented strength. Personally, its importance was such that a chapter based on the matter displaced another on the mysteries of Capilla del Monte in my book Invasores: Historias Reales de Extraterrestres en Argentina (Sudamericana, 2009).
The following is an abbreviated version of the most theoretical part of the chapter included in Invasores:
12 years ago, Argentina experienced its first ufological cow-icide. I started in April and reached its climax in June 2002, particularly in the province of Buenos Aires and the Pampean region. Farmhands, cattlemen and local residents woke up to find dead cows of all breeds and ages all over the place. Dozens of bovine carcasses rested near circles of flattened grass, near empty water tanks – drained by who knows what and for which reason – and others in unusual circumstances.
All of the animals presented as “proof” of the flap bore similar injuries: their edges were irregular, as though cauterized. According to farmhands and cattlemen, these incisions appeared to have a purpose. Their carcasses had been despoiled of their soft tissue (tongue, eyes, ears, nipples, genitals, udders) and sometimes they appeared exsanguinated. Locals would sink their knives into them and the blade would emerge dry, as if they had been plunged into a piece of pound cake.
The discovery of over two hundred mutilated animal carcasses was reported in less than three months, a ruthless and doubtful notion, but giving the impression that an intelligence had been at work and the deaths were not due to natural causes, such as the onset of the cold of winter or seasonal diseases followed by the instinct of certain predators looking for nourishment. Agreement between cattlemen, journalists, policemen and ufologists was overwhelming: the incisions looked artificial. These animals filled the ranks of the bizarre while predator activity was dismissed by some veterinarians in their homilies. The cult of the mutilated cow was confected by all of them, with or without an awareness of the subject.
The flap ended almost if by decree. On July 1, 2002, the National Food Safety and Quality Service (SENASA) blamed the weather and carrion animals. Presto: a mystery cauterized.
The official body stated that rodents belonging to the Oxymycterus rufus genus – among other vermin – had devoured the cattle in fine gourmet style while other victims lay dead as a result of ice storms, disease or natural causes. Bernardo Cané, the head of the organization, stated: “We are dismissing Martians, the Pombero and other rural Argentinean beliefs.” (1) The sentence would have been less odious if Cané had not ascribed the mutilations to “esoteric practices” a week earlier. (2) Forty-five days later he was dismissed from his position under suspicion of underhanded dealings. (3)
Other experts were also caught on the hop. Veterinarian Alejandro Martínez suspected “some sort of techno-cattle rustling” wielding the thermocauterizer (a pistol that fires darts) to underscore that the mysterious incisions could be caused by “any agency”. Pathologist Ernesto Odriozola supported “the actions of some madman”. Even the most experienced forensic pathologists stoked the mystery. Days later, SENASA disclosed the results of a necropsy performed on twenty animals collected from fifteen farms in different sections of Buenos Aires province. Cané presented his conclusions in a press conference: the cattle died “due to pneumonia, malnutrition, metabolic or infectious diseases that are highly prevalent during the winter season.” Thus, the mystery was halved: the mutilated cows…were already dead. The enigmatic incisions had been subsequently caused by various carrion animals, the red-muzzled mouse among them.
“Extraterrestrials Laugh at SENASA” proclaimed one of the screens of the Crónica TV channel. The mouse’s humorous moniker prompted the notion that it had all been a gag. It was around that time that I phoned Dr. Alejandro Soraci, one of the parties involved in the study conducted by Universidad Nacional del Centro (UNICEN). “Could you photocopy the report, and I’ll send for it?” But there was nothing to photocopy. The only material available, he explained, was the press release and the video of the mouse in action. SENASA results were simply two hastily drafted pages. The investigation could hardly be taken seriously with such apathy. “Why were mutilated cows found in places where the Oxymycterus isn’t found? And if it was the mouse, why didn’t SENASA undertake a campaign to control it?” wondered ufologist Quique Mario. To him, and to many other ufologist, the media oasis was deceitful. “Matters remain the same: nothing has changed. Two animals were found mutilated last Saturday, thirty kilometers from here. Last week there were five and seventeen down south, around Cuchillo Có,” he told me in mid-2003.
What factors were at play in unleashing the epidemic? Why now, and not before?
This is how SENASA – spokesman for official explanations – has belittled the human dimension of these experiences. Not everyone is willing to believe that cows are abducted by UFOs, or that a clandestine operation was set in motion to decimate the bovine population and attack those who came too close to the truth. It is also unfair that aliens should mock SENASA. The fact that the initial speculations of its experts should contradict the formal verdict speaks volumes about the fantasies that the mystery creates in all of them, scientists included. On the other hand, it doesn’t say as much about the quality of the study, which does not exempt SENASA from the mistake of making a pronouncement before the results were in hand.
The red-muzzled mouse’s leading role gave the matter an almost humorous cast: The scene-stealing and headline-grabbing mouse obscured the investigation’s credibility. It is possible that the media stressed the rodent’s involvement because there can be nothing better than a Supermouse to displace a Chupacabras. The irregular, serrated tooth marks of the Oxymycterus rufus appeared on the skin and bones of the analyzed animals. Those marks explained the origin of the strange incisions, some of them described as perfect circles. “Ever since Tom and Jerry, we know that a [mouse hole] has a circular opening. Rodents stand up and work from top to bottom,” explained Fernando Kravetz, full professor of Ecology in the School of Exact and Natural Sciences of the University of Buenos Aires. “The rodent population grew with the increase in the availability of dead animals due to classic diseases, changes in vegetation and pastures deteriorated by the ice storms. Crops are harvested in March and the weather changed abruptly in April.” (4)
The quantity and dispersion of dead animals did not startle the professor, considered the main expert in rural ecology. “If three hundred mutilations were reported, the existence of a total of two thousand carcasses could be estimated. A congruent number for that time of year.” SENASA also mentioned less photogenic predators, such as the Pampas fox, seagulls and armadillos. But the red-muzzled mouse was on the cover, because the cow mutilation wave resulted in the casual discovery of an unexpected mutation in it dietary habits. Up to 2002, it was believed to be an insectivore, but it feasted on beef when given the chance. Kravitz measured the marks appearing on the cattle’s toughest tissue (such as the base of the tongue) and found the same patterns as in “cattle mutilations”.
Nor was SENASA the only agency to reach a prosaic conclusion. The Animal Health Group of the National Livestock Technology Institute (INTA Balcarce) studied ten cases. “The incisions and absence of internal organs, ears and nipples are due to action by predators found in the region.” The causes behind these animal deaths – when they could be ascertained – were not mysterious either (intestinal parasites, mineral deficiencies, metabolic diseases, malnutrition) as well as the cold and ice storms that blanketed the southeastern region (5).
What SENASA neglected to do – never mind other official agencies that were unresponsive to the mystery – was to find a hypothesis able to answer a question that can be stated in three ways: Why did men experienced in cattle activities feel certain that those incisions were qualitatively different from those caused by other predators? How can the belief about the phenomenon’s novelty be justified? What changed so that some more or less ordinary deaths should turn into an epidemic? Perhaps the answers would offer no consolation to cattlemen and others impressed by direct experience, but it is better to try to answer tough questions that feel the breath of the Chupacabras on the nape of one’s neck again.
The cattle mutilation wave did not occur at just any moment in time. The harsh reality suggested that attention given to these “strange events” responded to the infinity of existing social concerns. The mystery, therefore, could be considered an outgrowth of the crisis. According to the theory’s most newfangled variant, the phenomenon had been deliberately inflated to distract the population from the nation’s state of malaise. But more than a smokescreen, the exaggerated diffusion of such news looked like another symptom of the same illness.
On December 19, 2001, a crowd of Argentineans took the streets, banging on cooking pots, to protest against a government asleep in the midst of the most brutal crisis of recent history. Ferocious reprisals followed the protests, resulting in thirty-nine dead at the hands of the police. Bank freezes, the uncontrolled dollar and high rates of unemployment added to the sad national ordeal. The ashes were still hot in 2002. Shortly before the wave of alien cattle rustling, the emblem of creole opulence had been prey to minor “depredations”. It is still hard to forget the image broadcast by a news program, when a truck with beef cattle overturned on the outskirts of Rosario, Santa Fe, in 2001 and a crowd surged to butcher the animals on the roadside. Other factors – frivolous to some, but serious in their psycho-social impact – fostered the dejected popular mood: around the same time, the Argentinean football team had been eliminated from the world cup in the first round.
For once, a modern expression of the supernatural drew the interest of two specialists in myth and legends. Martha Blache and Silvia Balzano, researchers with CONICET, put forth an explanatory model for the events. They suggested the possible interconnection between Chupacabras reports, the penetration of genetically-modified sorghum and the use of new herbicides whose preparation is controlled by American laboratories. They wondered, for example, if the phenomenon might not be a warning against the uncertainty created by these changes and the perceived lack of control evinced by cattlemen. Globalization may be related to the role played by a country that “benefits from our raw materials and natural resources, removing them in an efficient yet imperceptible manner,” without leaving traces. News about cattle mutilations, they write, seemed to condense a wider metaphor reflecting a country in a state of crisis that is trying to identify the culprits. Who is attacking the cows, tame and apathetic representative of Argentine heritage? Is our blood being sucked by international agencies or domestic carrion animals?” The popular imagination, they conclude, “could sublimate the conflicting demands of the IMF with regard to the foreign debt.” (6)
In proposing their model, Blache and Balzano did not conduct a survey on the political trends or the technical-scientific concerns of cattlemen. Implementing a sort of psycho-cultural analysis using press clippings is always risky. But the authors are the first to say that their hypothesis rests only on journalistic sources. At least they didn’t keep quiet.
The authors also noticed the similarity in the conclusions reached by Kenneth M. Rommel when the FBI assigned him to study the bovine massacre in the United States in 1980 and those of SENASA in 2002. In his study of twenty-seven cattle mutilations, Rommel ascribed the phenomenon to the combined effect of the media, the social influence of “experts” and the action of various predators in the genesis, formation and extension of the wave. (7) Both in the United States and Argentina, the mutilated carcasses were found according to pre-defined patterns. What the authors have termed “the media transmission chain” supposes the participation of narrators who contribute to disseminating a legend regardless of their posture toward it. This consensual version of the reality to be defined arises from an “identikit”, and these strangeness patterns configure, in turn a “selection criteria”. Thus, in order for the animal to belong to the category of “mutilated cattle”, it must meet a number of symptoms and even common scenarios. In order to build a “classic cattle mutilation scenario”, the animal must be found without its organs or soft tissue. The edges of its skin must be “clean, circular or with sharp angles” and the body must be as dry as possible, “as though exsanguinated”. Rommel did not find this “ideal case” in any of the one hundred seventeen mutilations he researched between 1975 and 1979, especially because – as in the Argentinean case – “surgical precision” vanished under the microscope and the exsanguination was only apparent. “Blood always pools in the lower parts of the carcass.” The missing parts – soft tissue organs – are the parts appealing to a carnivorous predator. He also discovered that the areas under the carcasses’ weight was also intact. An “intelligent mutilator” would have turned it over to devour the hidden parts. This was never the case.
[…]
In the United States, sociologist J.R. Stewart found that the number of cattle mutilation incidents was directly related to the volume of news devoted to the subject in the media. He also interviewed eight hundred adults and determined that the police, having no experience in elucidating the causes of cattle deaths, and certain local vets, more accustomed to treating live animals, were inclined to accept the farmers’ eyewitness accounts (9). A similar study was not performed in Argentina, but the phenomenon came to an end when the media moved on to other subjects. Application of the “pitted windshield theory” can lead one to think of a case of selective perception molded by the stereotype provided by the media. I must stress that I am not a sociologist who can reduce the phenomenon to a case of mass hysteria. Even so, this theory seems more convincing to me than finding explanations in the incursions of a bloodthirsty Chupacabras, aliens hankering to throw some creole spareribs on the grill or a gang of lunatic scientists injecting strange potions into our cows.
For the moment, we know that the media is accustomed to broadcasting mutilated images of reality, and we cannot ask cows for their opinion. They can’t even moo. The red muzzled mouse – Professor Kravetz told me – swallowed their tongues.

Several Ancient Viruses Have Been Discovered in 15,000-Year-Old Glacial Ice
Several Ancient Viruses Have Been Discovered in 15,000-Year-Old Glacial Ice
KRISTIN HAUSER, FUTURISM
In 2015, a team of scientists from the United States and China traveled to Tibet to gather samples of Earth's oldest glacial ice.
Earlier this month, they published a paper on the pre-print server bioRxiv detailing their discovery of 28 new virus groups in the 15,000-year-old ice - and warning that climate change could free the ancient viruses into the modern world.
The team drilled 50 meters (164 feet) down into the glacier to obtain two ice cores, which then underwent a three-step decontamination protocol.
After that, the researchers used microbiology techniques to identify microbes in the samples.
Those techniques revealed 33 virus groups - including, notably, 28 ancient viruses that scientists had never seen before.
"This study establishes ultra-clean microbial and viral sampling procedures for glacier ice, which complements prior in silico decontamination methods and expands, for the first time, the clean procedures to viruses," the team wrote.
As the team pointed out in their paper, climate change now threatens both our ability to exhaustively catalogue those tiny lifeforms - as well as our ability to stay safe from dangerous ones.
"At a minimum, [ice melt] could lead to the loss of microbial and viral archives that could be diagnostic and informative of past Earth climate regimes," they wrote.
"However, in a worst-case scenario, this ice melt could release pathogens into the environment."
Led by Catherine LaFarge, a geologist from the University of Alberta in Edmonton (Canada), they were exploring an area called the Sverdrup Pass, which until just recently had been covered by ice. The Teardrop Glacier had spread all across Ellesmere Island during the Little Ice Age, a global cold spell that affected weather and climate conditions in the Northern Hemisphere between 1550 and 1850.
While trudging across newly exposed ground, the scientists found clumps of moss that were mostly browned or blackened. But in among this dead plant life were some spots of green, indicating that a process of regeneration and regrowth had started to occur.
This was remarkable, because LaFarge and the other scientists knew they were not looking at moss that had grown recently. What they’d discovered had originally lived and died several hundred years ago, and it had been trapped beneath the ice for several centuries. Incredibly, moss that had been buried and frozen solid beneath the Teardrop Glacier had begun to regenerate, as if it hadn’t been affected by its centuries-long entombment at all.
LaFarge was able to identify these moss samples as bryophytes, which are extremely resilient plants that have been on Earth for millenia. They are vital contributors to the health and vitality of polar ecosystems, playing a role in their creation and maintenance. They’d been hardy enough to survive in the harsh Arctic climate in the first place, and now that warming trends had exposed them to the open air they had sprung to life once again. They had likely been exposed to the open air for about two years by the time they’d been discovered by the Canadian scientists.
The scientists took samples of the bryophytes back to their laboratory for further study and experimentation. Radiocarbon dating methods confirmed that the moss was approximately 400 years old, yet its ability to produce new life had not been extinguished by the trauma it had experienced.
To test its potency, LaFarge and her team sliced the moss into sections and placing them in controlled environments where light, temperatures and nutrition were ideal for growing. Eventually, seven out of 24 samples sprouted new plants, which to all appearances were perfectly healthy and vibrant.
As LaFarge explained, new moss doesn’t grow from seeds or spores, but from individual plant cells that can create copies of themselves directly. This unique quality may contribute to moss’s ability to regenerate quickly and robustly, even after being placed in suspended frozen animation underneath a glacier for more than four centuries.
More Moss Miracles
This important discovery forced biologists to revise their ideas about the ability of life to survive frozen conditions. But as remarkable as this finding was, scientists affiliated with the British Antarctic Survey and Reading University did their Canadian counterparts one better .
In 2014, just one year after the Ellesmere Island discovery, the British scientists retrieved moss samples from deep inside a frozen moss bank found on the Antarctic tundra. Using radiocarbon dating, they discovered the moss was approximately 1,500 years old. But despite its tremendous antiquity, when the plants were sliced into sections and placed inside an incubator, after a few weeks they, too, began to regenerate.
Even after suffering through the deepest of deep freezes in the coldest continent on our planet, these moss samples had not lost their capacity to regenerate when given enough light, water and nutrition.
“This experiment shows that multi-cellular organisms, plants in this case, can survive over far longer timescales than previously thought,” said Professor Peter Convey, one of the lead scientists involved in this study. “These mosses, a key part of the ecosystem, could survive century to millennial periods of ice advance.”
“If they can survive in this way,” he continued,” then recolonisation following an Ice Age, once ice retreats, would be a lot easier than migrating trans-oceanic distances from warmer regions. It also maintains diversity in an area that would otherwise be wiped clean of life by the ice advance.”
And while the idea may seem farfetched, Convey mentions another possibility that has probably occurred to everyone who has heard this story.
“Although it would be a big jump from the current finding, this does raise the possibility of complex lifeforms surviving even longer periods once encased in permafrost or ice.”
Convey doesn’t specify what he means by “complex lifeforms.” But it boggles the mind to think about what might be buried under the glaciers that cover the polar realms. One thing we know for sure is that thanks to global warming, much of the land that is currently ice covered above the Arctic Circle and near the South Pole may eventually be exposed.
Could Rampaging Viruses —or Vegetable Men —Be Next?
There are many science fiction movies that feature the reanimation of living creatures frozen solid in ice. In 1951’s “The Thing from Another World,” a man-eating, six-foot tall vegetable from another planet, originally encased in a block of ice, terrorizes the occupants of an Arctic research station after accidentally being thawed out by an electric blanket. In 1967’s “The Frozen Dead,” a mad scientist thaws and resuscitates Nazi soldiers he’s kept stored on his English country estate, unaware that they’ve been converted into bloodthirsty zombies.
Far-out storylines like this might appear to have no connection to defrosted and revived moss. But just because moss is benign, that doesn’t mean there aren’t dangers inherent in thawing out lifeforms that lived in others epoch. Some of these lifeforms could very well represent a threat to the health and safety of humanity, and scientists should think carefully about the possible ramifications before opening Pandora’s box and reviving everything they can find.
In the real world, the concern is not so much about frozen animals, Neanderthals, or aliens from crashed spaceships. The real fear is that scientists might mistakenly activate long-dormant viruses or bacteria that we would have no capacity to resist. As human activity continues to heat the planet, the thawing of the tundra in Siberia and the retreat of the glaciers inside the Arctic Circle and in Antarctica could release and reactivate hidden and potentially lethal microorganisms. If such a scenario were to be realized, we could be exposed to hazards that might be even more deadly than Nazi zombies or alien vegetable-men.
The possibility of such an event is not strictly theoretical. In 2014, a group of French scientists revived an ancient virus found frozen in a soil sample taken from 30 metres below the icy tundra of eastern Siberia. Dubbed Pithovirus Sibericum , this gigantic virus was far larger and more complex than the viruses we see today, and is believed to evolved entirely separately from modern infectious agents.
Fortunately, this virus was found to be harmless to humans. But the next one or the next one after that could be lethal, and if humans are unwittingly exposed to it because of thawing tundra there is no telling how much damage it might do.

Ancient Mystery Viruses Discovered Sealed Within Tibetan Glacier For 15,000 Years
Ancient Mystery Viruses Discovered Sealed Within Tibetan Glacier For 15,000 Years
Scientists have found 28 new groups of ancient viruses buried deep within a cold slumber. The viruses were discovered inside the cores of a 15,000-year-old Guliya ice cap on the Tibetan Plateau.
In their paper available on bioRxiv, researchers explain that contaminating such samples of viruses is not difficult. Hence, scientists employed a new method to study microbes preserved within the ice for ultraclean microbial and viral sampling, according to LiveScience.
They employed their techniques to study two ice core samples of the Tibetan glaciers which were collected and stored previously without special care against contamination. So, the exteriors were contaminated but the insides of the samples were still in mint condition.
The team was able to access the samples by gradually getting rid of the outer layers of ice by various methods. In a cold room maintained at -5°C, researchers used a sterilized band to cut a layer of ice, followed by ethanol to melt another layer of ice and then washed with sterile water to remove another layer. A total of 1.5 centimetres of ice was removed to reach an uncontaminated layer. The researchers found 33 groups of virus genera of which, 28 were previously unknown. The microbes found in each ice core differed from the others, indicating that they were stored at different periods of climate conditions.
While these microbes were studied by researchers in controlled conditions, it is possible that the ice melt due to global warming might cause such ancient microbes to be released into the environment. The researchers in their paper explained, “At a minimum, this could lead to the loss of microbial and viral archives that could be diagnostic and informative of past Earth climate regimes; however, in a worst-case scenario, this ice melt could release pathogens into the environment.”
Using new geochemical models, SwRI scientists found that CO2 in Enceladus' ocean may be controlled by chemical reactions at the seafloor. Integrating this finding with previous discoveries of H2 and silica suggests geochemically diverse environments in the rocky core.

A Southwest Research Institute team developed a new geochemical model that reveals that carbon dioxide (CO2) from within Enceladus, an ocean-harboring moon of Saturn, may be controlled by chemical reactions at its seafloor. Studying the plume of gases and frozen sea spray released through cracks in the moon's icy surface suggests an interior more complex than previously thought.
"By understanding the composition of the plume, we can learn about what the ocean is like, how it got to be this way and whether it provides environments where life as we know it could survive," said SwRI's Dr. Christopher Glein, lead author of a paper in Geophysical Research Letters outlining the research. "We came up with a new technique for analyzing the plume composition to estimate the concentration of dissolved CO2 in the ocean. This enabled modeling to probe deeper interior processes."
Analysis of mass spectrometry data from NASA's Cassini spacecraft indicates that the abundance of CO2 is best explained by geochemical reactions between the moon's rocky core and liquid water from its subsurface ocean. Integrating this information with previous discoveries of silica and molecular hydrogen (H2) points to a more complex, geochemically diverse core.
"Based on our findings, Enceladus appears to demonstrate a massive carbon sequestration experiment," Glein said. "On Earth, climate scientists are exploring whether a similar process can be utilized to mitigate industrial emissions of CO2. Using two different data sets, we derived CO2 concentration ranges that are intriguingly similar to what would be expected from the dissolution and formation of certain mixtures of silicon- and carbon-bearing minerals at the seafloor."
Another phenomenon that contributes to this complexity is the likely presence of hydrothermal vents inside Enceladus. At Earth's ocean floor, hydrothermal vents emit hot, energy-rich, mineral-laden fluids that allow unique ecosystems teeming with unusual creatures to thrive.
"The dynamic interface of a complex core and seawater could potentially create energy sources that might support life," said SwRI's Dr. Hunter Waite, principal investigator of Cassini's Ion Neutral Mass Spectrometer (INMS). "While we have not found evidence of the presence of microbial life in the ocean of Enceladus, the growing evidence for chemical disequilibrium offers a tantalizing hint that habitable conditions could exist beneath the moon's icy crust."
The scientific community continues reaping the benefits of Cassini's close flyby of Enceladus on Oct. 28, 2015, prior to the end of the mission. INMS detected H2 as the spacecraft flew through the plume, and a different instrument had earlier detected tiny particles of silica, two chemicals that are considered to be markers for hydrothermal processes.
"Distinct sources of observed CO2, silica and H2 imply mineralogically and thermally diverse environments in a heterogeneous rocky core," Glein said. "We suggest that the core is composed of a carbonated upper layer and a serpentinized interior." Carbonates commonly occur as sedimentary rocks such as limestone on Earth, while serpentine minerals are formed from igneous seafloor rocks that are rich in magnesium and iron.
It is proposed that hydrothermal oxidation of reduced iron deep in the core creates H2, while hydrothermal activity intersecting quartz-bearing carbonated rocks produces silica-rich fluids. Such rocks also have potential to influence the CO2 chemistry of the ocean via low-temperature reactions involving silicates and carbonates at the seafloor.
"The implications for possible life enabled by a heterogeneous core structure are intriguing," said Glein. "This model could explain how planetary differentiation and alteration processes create chemical (energy) gradients needed by subsurface life."

Door de immense klap kwam er veel waterdamp vrij, wat een einde maakte aan de bevroren staat van onze aarde.
Onderzoekers hebben zich in een nieuwe studie gepubliceerd in het toonaangevende tijdschrift Nature Communications gebogen over de Yarrabubba-krater. Deze krater is te vinden in het binnenland van West-Australië en is ontstaan door een inslag van een meteoriet. De bevindingen zijn zeer interessant. Want niet alleen hebben de onderzoekers de leeftijd van de krater weten te achterhalen, het is ook gelukt om de gevolgen van de impact bloot te leggen.
Leeftijd Het team besloot allereerst de precieze leeftijd van de krater te bepalen. “Yarrabubba was al vele jaren erkend als inslagkrater,” zegt onderzoeker Chris Kirkland. “Maar tot nu toe wist men nog niet hoe oud deze eigenlijk was.” Na een grondige analyse van de aangetroffen mineralen zirkoon en monaziet, zijn de onderzoekers erachter gekomen dat de Yarrabubba-krater een slordige 2.229 miljard jaar oud is. En dat is bijzonder oud. Sterker nog, het betekent dat deze krater de oudste op aarde is. De Yarrabubba-krater blijkt daarnaast zo’n 200 miljoen jaar ouder dan de eerstvolgende inslagkrater

Bovendien lukte het de onderzoekers om een beeld van de meteoriet-inslag te schetsen. Waarschijnlijk stortte de meteoriet neer in een met ijs bedekt landschap. Hierdoor verdampte een grote hoeveelheid ijs dat vervolgens naar de atmosfeer werd getransporteerd. De inslag vormde bovendien een enorme krater met een diameter van wel 70 kilometer.
Sneeuwbalaarde Door verschillende gegevens en informatie over onze aarde naast elkaar te leggen, kwamen de onderzoekers erachter dat de inslag een grote klimaatverandering teweeg heeft gebracht. En dat is interessant. Waarschijnlijk heeft de meteoriet-inslag er namelijk voor gezorgd dat de eens bevroren aarde begon te ontdooien. “De Yarrabubba-krater ontstond aan het einde van wat ook wel de sneeuwbalaarde wordt genoemd,” legt Kirkland uit. In die tijd was de aarde volledig bedekt met ijs en herbergde bevroren oceanen. Maar op een bepaald moment werden oceanen zuurstofrijker en verdween het ijs. En het zou best weleens kunnen dat de meteorietinslag in de Yarrabubba-krater daarvoor het startschot gaf. “De leeftijd van de inslagkrater komt overeen met de ondergang van een reeks oude ijstijden,” legt onderzoeker Nicholas Timms uit. “Na de inslag zien we in de data 400 miljoen jaar lang geen ijsafzettingen. Deze speling van het lot suggereert dat de grote meteorietinslag invloed kan hebben gehad op het wereldwijde klimaat.”
Waterdamp Om daar een goed beeld van te krijgen, besloten de onderzoekers er wat modellen op los te laten. “Berekeningen gaven aan dat een dergelijke inslag op een met ijs bedekt continent een half biljoen ton waterdamp – een belangrijk broeikasgas – de atmosfeer in stuurde,” zegt Timms. En het zou heel goed kunnen dat dit een einde heeft gemaakt aan de bevroren staat van onze planeet.
De bevindingen hebben belangrijke implicaties voor toekomstige ontdekkingen van inslagkraters. “De resultaten benadrukken dat het belangrijk is om de precieze leeftijd van kraters te achterhalen,” zegt onderzoeker Aaron Cavosie. “Het bestaan van de Yarrabubba-krater was al zeker twee decennia bekend, maar nu pas weten we hoe oud hij is.” En dankzij deze informatie krijgen wetenschappers een steeds beter beeld van de geschiedenis van de aarde. De vraag is nu of de Yarrabubba-krater de oudste zal blijven, of dat onderzoekers op nóg oudere inslagkraters gaan stuiten. “Het roept de vraag op of alle oudere inslagkraters zijn geërodeerd, of dat ze nog steeds wachten om ontdekt te worden,” besluit Cavosie.
The Earth could be headed for a 'mini ice age' researchers have warned.
A new study claims to have cracked predicting solar cycles - and says that between 2020 and 2030 solar cycles will cancel each other out.
This, they say, will lead to a phenomenon known as the 'Maunder minimum' - which has previously been known as a mini ice age when it hit between 1646 and 1715, even causing London's River Thames to freeze over.

THE SOLAR CYCLE
Conventional wisdom holds that solar activity swings back and forth like a simple pendulum.
At one end of the cycle, there is a quiet time with few sunspots and flares.
At the other end, solar max brings high sunspot numbers and frequent solar storms.
It's a regular rhythm that repeats every 11 years.
Reality is more complicated.
Astronomers have been counting sunspots for centuries, and they have seen that the solar cycle is not perfectly regular.
The new model of the Sun's solar cycle is producing unprecedentedly accurate predictions of irregularities within the Sun's 11-year heartbeat.
It draws on dynamo effects in two layers of the Sun, one close to the surface and one deep within its convection zone.
Predictions from the model suggest that solar activity will fall by 60 per cent during the 2030s to conditions last seen during the 'mini ice age' that began in 1645, according to the results presented by Prof Valentina Zharkova at the National Astronomy Meeting in Llandudno.
The model predicts that the pair of waves become increasingly offset during Cycle 25, which peaks in 2022.
During Cycle 26, which covers the decade from 2030-2040, the two waves will become exactly out of synch and this will cause a significant reduction in solar activity.
'In cycle 26, the two waves exactly mirror each other – peaking at the same time but in opposite hemispheres of the Sun,' said Zharkova.
'Their interaction will be disruptive, or they will nearly cancel each other.
'We predict that this will lead to the properties of a 'Maunder minimum''
'Effectively, when the waves are approximately in phase, they can show strong interaction, or resonance, and we have strong solar activity.
'When they are out of phase, we have solar minimums.
'When there is full phase separation, we have the conditions last seen during the Maunder minimum, 370 years ago.'
THE MAUNDER MINIMUM
The Maunder Minimum (also known as the prolonged sunspot minimum) is the name used for the period starting in about 1645 and continuing to about 1715 when sunspots became exceedingly rare, as noted by solar observers of the time.
It caused London's River Thames to freeze over, and 'frost fairs' became popular.
This period of solar inactivity also corresponds to a climatic period called the 'Little Ice Age' when rivers that are normally ice-free froze and snow fields remained year-round at lower altitudes.
There is evidence that the Sun has had similar periods of inactivity in the more distant past, Nasa says.
The connection between solar activity and terrestrial climate is an area of on-going research.
Some scientists hypothesize that the dense wood used in Stradivarius instruments was caused by slow tree growth during the cooler period.
Instrument maker Antonio Stradivari was born a year before the start of the Maunder Minimum.
Maunder Minimum (also known as the prolonged sunspot minimum) is the name used for the period starting in about 1645 and continuing to about 1715 when sunspots became exceedingly rare, as noted by solar observers of the time
It is 172 years since a scientist first spotted that the Sun's activity varies over a cycle lasting around 10 to 12 years.
But every cycle is a little different and none of the models of causes to date have fully explained fluctuations.

Many solar physicists have put the cause of the solar cycle down to a dynamo caused by convecting fluid deep within the Sun.
Now, Zharkova and her colleagues have found that adding a second dynamo, close to the surface, completes the picture with surprising accuracy.
'We found magnetic wave components appearing in pairs, originating in two different layers in the Sun's interior,' she said.
'They both have a frequency of approximately 11 years, although this frequency is slightly different, and they are offset in time.
'Over the cycle, the waves fluctuate between the northern and southern hemispheres of the Sun. Combining both waves together and comparing to real data for the current solar cycle, we found that our predictions showed an accuracy of 97%,' said Zharkova.
Montage of images of solar activity between August 1991 and September 2001 taken by the Yohkoh Soft X-ray Telecope, showing variation in solar activity during a sunspot cycle.
Zharkova and her colleagues derived their model using a technique called 'principal component analysis' of the magnetic field observations from the Wilcox Solar Observatory in California.
They examined three solar cycles-worth of magnetic field activity, covering the period from 1976-2008.
In addition, they compared their predictions to average sunspot numbers, another strong marker of solar activity.
All the predictions and observations were closely matched.

Als je ze ziet twinkelen aan de hemel zou je het niet zeggen. Maar al deze sterren worden mede mogelijk gemaakt door catastrofale explosies. En velen ervan komen door zo’n zelfde explosie aan hun einde.
Je hebt vast wel eens naar de hemel gestaard en je misschien afgevraagd wat al deze lichtpuntjes die wij sterren noemen nu werkelijk zijn en hoe het leven van een ster, zoals onze zon, begint en verdergaat. Na het lezen van dit artikel heb je antwoorden op al deze vragen.
Geboorte Sterren ontstaan door het samentrekken van gaswolken (nevels) die wel enkele lichtjaren – de afstand die licht aflegt in een jaar tijd – breed kunnen zijn. De ineenstorting ontstaat onder de invloed van zijn eigen gewicht en de zwaartekracht. Dit proces kan enkele honderdduizenden jaren duren. Het grootste deel van zo’n gaswolk bestaat uit de lichtste elementen van ons universum: waterstof en helium. De rest zijn zwaardere elementen. Dit zijn overblijfselen van oudere sterren die aan hun einde gekomen zijn door middel van een supernova explosie. Hier komen we later op terug. Zodra zo’n gaswolk begint ineen te storten, zal ook de temperatuur stijgen. Niet al het materiaal beweegt zich naar één punt, maar een gaswolk splitst zich op in meerdere subgaswolken. In de kern van zo’n subgaswolk komt materiaal samen en begint steeds sneller rond te draaien. Als gevolg daarvan wordt er een compact lichaam gevormd dat we een protoster noemen. De hoeveelheid van het beschikbare materiaal bepaalt hoe heet en groot de ster wordt. Ook komt het regelmatig voor dat er een dubbelstersysteem of soms zelfs een meervoudig sterysteem ontstaat, waarbij er dus meerdere sterren gravitationeel aan elkaar gebonden zijn.
Niet al het materiaal van een subgaswolk vormt een protoster. Dit betekent dat een ander deel rond de protoster in banen blijft draaien. Dit wordt de protoplanetaire schijf genoemd, waaruit later planeten kunnen ontstaan. Ondertussen stopt langzaam de ineenstorting van het materiaal van de protoster, doordat er ook een uitwaartse stralingsdruk is vanuit de kern. Zodra de zwaartekracht en de stralingsdruk in balans zijn, is de protoster stabiel en wordt dan een ster genoemd. De temperatuur is door de samendrukking van de atomen hoog genoeg geworden om kernfusie op gang te laten komen. Je kunt dan ook wel zeggen dat een ster eigenlijk een natuurlijke kernfusiereactor is.
Kernfusie Als eerste worden waterstofatomen door kernfusiereacties gefuseerd tot heliumatomen. Vier waterstofatomen zijn gelijk aan één heliumatoom plus een resterende massa. Deze overgebleven hoeveelheid massa wordt door de welbekende formule van Einstein 𝐸 = 𝑚𝑐2 omgezet in energie. Deze energie zorgt voor extra weerstand tegen ineenstorting. Over het volledig omzetten van een waterstofkern naar helium doet een gemiddelde ster ongeveer 90% van zijn leven (een ster leeft miljarden jaren). Zodra de ster zijn waterstof volledig ‘opgebrand’ heeft in de kern, stoppen de kernfusies en heb je een heliumkern. Omdat de temperatuur nog niet hoog genoeg is om helium te gaan fuseren, begint de kern weer in elkaar te krimpen en de temperatuur te stijgen. Aan de buitenrand van de kern zit nog waterstof en deze temperatuur stijgt ook, totdat het hier warm genoeg is voor de fusie van waterstof. De kern krimpt in de tussentijd, waardoor de temperatuur steeds meer toeneemt en de waterstoffusie in de buitenrand van de kern versnelt. Uiteindelijk is de temperatuur in de kern hoog genoeg geworden om helium te gaan fuseren tot koolstof en zuurstof.
Kernfusie. Links tijdens waterstoffusie, rechts tijdens heliumfusie in de kern en waterstoffusie in een schil er omheen.
Rode reus Als er buiten de kern een fusieproces plaatsvindt, gaat de ster plotseling veel meer energie opwekken en begint op te zwellen. Doordat de oppervlakte toeneemt, neemt de oppervlaktetemperatuur af en verandert de ster van kleur. In dit stadium wordt de ster een ‘rode reus’ genoemd. Dit is een vrij instabiele periode in het leven van een ster. De ster is aan het opzwellen en inkrimpen. Als een ster lichter is dan 2,2 maal de massa van de zon en de temperatuur opgelopen is tot 100-200 miljoen, ontstaat er een plotselinge heliumflits. Tijdens zo’n heliumflits komt er net zoveel energie vrij als alle sterren in de Melkweg in dezelfde periode opwekken. Bij zwaardere sterren gaat de kernfusie van helium naar koolstof en zuurstof een stuk geleidelijker, waardoor er geen plotselinge heliumflits ontstaat.
Laatste levensfases Wat er volgt in het leven van een ster is sterk afhankelijk van de grootte van de ster. Je zou misschien verwachten dat een kleinere ster een korter leven heeft. Dit is niet zo. Hoe groter, hoe korter het leven, omdat de kernfusies langzamer gaan in kleinere sterren. Zo kan de lengte van het leven van een ster variëren tussen de 1 miljoen en 100 miljard jaar. Sterren met een massa tussen de 0,08 en 0,5 maal de massa van de zon, worden ‘rode dwergen’ genoemd. Over hun laatste levensfases is weinig bekend, omdat ons universum nog te jong is om dit type ster de tijd te geven om op een natuurlijke manier aan zijn einde te komen. Voor sterren die lichter zijn dan achtmaal de massa van onze zon, is er geen volgende stap nadat het helium in de kern uitgefuseerd is, omdat er geen temperatuur behaald kan worden die zorgt voor fusie van koolstof. Uiteindelijk zal de kern samendrukken totdat er geen samenpersing meer mogelijk is. Op dit moment heet de ster een ‘witte dwerg’. De witte dwerg kan zijn buitenste lagen niet meer vasthouden en deze worden afgestoten en vormen een planetaire nevel (dit heeft overigens niks met planeten te maken). Dit lot staat onze zon dus ook te wachten. Maar geen paniek: het duurt nog 5 miljard jaar voordat onze zon door zijn waterstofvoorraad heen zal zijn.
“BEDENK DAT BIJNA AL HET MATERIAAL DAT JE IN HET DAGELIJKS LEVEN OM JE HEEN ZIET, OF HET IJZER DAT IN JE BLOED ZIT, UITEINDELIJK GROTENDEELS GEPRODUCEERD IS IN ZWARE STERREN”
Voor sterren die grofweg zwaarder zijn dan achtmaal de massa van onze zon is het wel mogelijk om een temperatuur te bereiken waarbij koolstof gefuseerd kan worden tot neon. Verder vindt nog, in verschillende lagen rond de kern, fusie van de lichtere elementen (waterstof, helium en koolstof) plaats. Hoe dichter bij de kern, hoe warmer en hoe zwaarder de elementen zijn die gefuseerd worden. De kernfusies van steeds zwaardere elementen gaan door totdat ijzer in de kern ontstaat. Dit element wordt niet gefuseerd tot zwaardere elementen, omdat de fusie in plaats van energie oplevert, juist energie kost. Als gevolg valt de druk vanuit de kern weg en stort de ster in onder zijn eigen zwaartekracht. Dit resulteert in een heftige explosie, welke ook wel bekend staat als een supernova. Voor sterren met een kern lichter dan driemaal de massa van de zon, blijft de kern over als een neutronster. Dit is een ster met een enorme grote dichtheid. Het kan zijn dat zo’n ster misschien maar een diameter van 10 km heeft, terwijl het gelijk is aan de massa van de zon. Als de ster zwaarder is, dan zal de kern imploderen en veranderen in het welbekende – maar toch mysterieuze – zwarte gat. Dit is een extreem compacte ‘massa’, die de ruimtetijd heftig vervormt. Hieraan kan niks ontsnappen, zelfs licht niet.
De elementen die door een supernova uitgestoten worden, zijn de zware elementen die weer in andere gaswolken terechtkomen. De explosie van zo’n supernova kan ook een gaswolk weer triggeren om ineen te storten. Op deze manier ontstaan er weer nieuwe sterren en begint het hele verhaal weer van voor af aan…

Caroline Kraaijvanger
Het zou zomaar kunnen nu er recent – na een lange periode van afwezigheid – weer zonnevlekken op onze moederster zijn gespot.
De dag voor kerst zagen astronomen twee groepen zonnevlekken op onze moederster. Nu hoor ik je denken: zo bijzonder is dat toch niet? Nou, de astronomen keken er toch even van op. Want de zon was al sinds 14 november 2019 vrij van zonnevlekken. De laatste keer dat de zon zo’n lange periode zonnevlekvrij was, was in 1996.
Cyclus Die inactiviteit is te herleiden naar de cyclus van de zon. Onze moederster doorloopt namelijk een grofweg 11 jaar durende cyclus die gekenmerkt wordt door een zonneminimum – een periode waarin de zon heel rustig is en weinig zonnevlekken en zonnevlammen genereert – en een zonnemaximum, waarin de ster juist veel actiever is. Het zonnemaximum vond in 2014 plaats. Sindsdien neemt de activiteit op de zon af en is het wachten op het zonneminimum dat tevens het einde van deze zonnecyclus en het begin van een nieuwe markeert. Onderzoekers voorspelden eerder dat het zonneminimum zich rond april 2020 aan zou dienen. Maar dat kon ook zes maanden later of zes maanden eerder worden; de ervaring leert dat de zon het niet zo nauw neemt met de tijd.
Nu er na een lange periode van rust weer zonnevlekken op de zon opduiken, is de grote vraag of dit dan het zonneminimum was en daarmee dus een nieuwe zonnecyclus is aangebroken. Wetenschappers hebben meer data nodig om met zekerheid te kunnen zeggen dat deze zonnevlekken daadwerkelijk een nieuwe zonnecyclus inluiden, maar dat een nieuwe cyclus aanstaande is, staat vast en wordt door de komst van de zonnevlekken duidelijk onderschreven.
Wat brengt het ons? Wat die nieuwe zonnecyclus ons brengt, is altijd enigszins koffiedik kijken. De ene cyclus is namelijk de andere niet. Soms verloopt zo’n cyclus – zoals het exemplaar waar we nu nog net (of net niet meer) inzitten – vrij gemoedelijk en is de zon zelfs tijdens het zonnemaximum nog relatief rustig. Maar er zijn ook cycli geweest waarin het zonnemaximum gekenmerkt werd door een hoop onrust op de zon. Die onrust komt tot uiting in veel zonnevlekken, zonnevlammen, en meerdere zogenoemde coronale massa-ejecties per dag. Met name die coronale massa-ejecties kunnen nog weleens venijnig zijn; tijdens deze uitbarstingen op de zon worden energierijke deeltjes en magnetische velden de ruimte ingeslingerd. Deze kunnen behalve een fraai poollicht genereren, ook schade aanrichten aan satellieten in een baan rond de aarde en – in uitzonderlijke gevallen – zelfs voor problemen zorgen op aarde (zie kader).
Onze aarde wordt omringd door een magnetisch veld dat ons onder meer beschermt tegen de grillen van de zon. Maar heel soms schiet dat aardmagnetisch veld tekort. Dat kan gebeuren als er sprake is van een samenloop van omstandigheden die leidt tot een extreme, op de aarde gerichte, uitbarsting op de zon. Dat gebeurde bijvoorbeeld in 1859. Een coronale massa-ejectie raakte toen de aardse magnetosfeer – de invloedssfeer van het magnetisch veld dat de aarde zelf genereert – waardoor deze verstoord raakte. Het leidde tot het uitvallen van de telegraafverbinding tussen Europa en Amerika. En in 1989 zorgde de zon er zo voor dat een elektriciteitsnetwerk in Canada werd uitgeschakeld en zo’n zes miljoen mensen meer dan negen uur zonder stroom zaten.
Gezien de impact die een actieve zon op de aarde en omgeving kan hebben, is er onderzoekers veel aan gelegen om te kunnen voorspellen wat een zonnecyclus gaat brengen. Maar dat is zo gemakkelijk nog niet. Want nog steeds weten we niet precies hoe onze ster met name diep van binnen werkt. Toch wagen sommige onderzoekers zich wel aan een voorspelling. En die is enigszins geruststellend. Naar verwachting wordt de volgende zonnecyclus net als de cyclus waar we nu in zitten (of net uit zijn gerold) vrij rustig. Sterker nog: NASA voorspelde vorig jaar dat het wel eens de zwakste zonnecyclus in 200 jaar tijd zou kunnen worden, waarbij de intensiteit van het zonnemaximum – gemeten in het aantal zonnevlekken – 30 tot 50% lager ligt dan in de meest recente zonnecyclus. Het zou goed nieuws zijn voor de plannen van NASA, die in 2024 – dus rondom het zonnemaximum – mensen naar de maan wil sturen en daar geen gevaarlijk ruimteweer bij kan gebruiken.
NASA abruptly cuts live feed ISS after THIS appears over the U.S.
NASA abruptly cuts live feed ISS after THIS appears over the U.S.
The ISS live feed was interrupted by NASA at the moment a weird UFO-like anomaly appears in front of the the camera.
Jujubee's Adams had just turned on his ISS app to take a look when some kind of object appeared on the live feed, so Adams took some photos and a video of the strange anomaly, just before NASA abruptly cuts the live broadcast.
And it is not the first time NASA cuts the live feed from the International Space Station. At the moment alien objects appear on camera, they switch over to the well known screen and text that there is a sudden loss of signal between the station and the communications network.
The following video recorded by Adams on January 22, 2020 is a clear example of how NASA is trying to disguise the existence of UFOs and other unknown advanced objects in space.

Pilot captures unusual cigar-shaped object soaring over Utah from cockpit
A plane pilot appears to have captured a cigar-shaped UFO at 40,000ft soaring through the air above Utah.
The footage – taken over Zion National Park in the US state – shows the strange white object making its way across the sky.
Its shape appears much like a cigar or even a tic-tac – matching dozens of similar sightings over the past few months.
Given the altitude of the craft, it is difficult to see how fast it is travelling.
The clip was taken back in September 2019, but the footage only surfaced yesterday after being posted by YouTube channel Tales From Out There.
In the video description, the uploader said: “Video recording is taken from a cockpit at 40,000ft of an object flying at a lower altitude over the terrain.

“Not sure what it is.” He added in the title he believed it could be a “flying disc”.
Viewers soon flooded in to voice their thoughts, with one writing: “That’s an alien ship.”
“Nice proof,” another said, believing the extraterrestrial explanation.
Another wrote: “Where is the flying disc? I only see a white stripe.”
Others were less convinced, though. One sceptic suggested the distance and angle meant it “could easily be another plane”.

A second claimed it was nothing more than a “smudge on a window” while a third believed it was a “weather balloon”.
The footage comes days after footage emerged of a mysterious tube-shaped object hovering in the skies above Massachusetts.
Cameraman John Baglio told Daily Star Online the craft had “two big lights” at the front and was “the size of a bus”.
A new research study suggests that K-type dwarf stars (smaller and cooler than our sun) are the best place to search for alien life. These stars are not too hot, not too cool, and not too violent for life to evolve.
Size comparison of G dwarfs (sunlike) stars, K dwarfs and M dwarfs.
Astronomers use the term Goldilocks zoneto describe a star’s habitable zone, where temperatures can allow liquid water to exist on a rocky planet. This zone around a star is generally thought to be the best place to search for life beyond our solar system. Now, scientists are also speaking of Goldilocks stars that are not too hot, too cool, or too violent for life to evolve on any suitable planets. This emerging scenario is based on three decades of observations of exoplanets and their stars.
The new program, called the GoldiloKs Project, is being led by Edward Guinan and Scott Engle of Villanova University in Pennsylvania. The project involves undergraduate students measuring the age, rotation rate, and X-ray and far-ultraviolet radiation in a sampling of mostly cool G dwarf (sunlike yellow dwarfs) and K dwarf (orange dwarf) stars. Data was obtained from various telescopes and satellites, including Hubble Space Telescope, Chandra X-ray Observatory, and XMM-Newton. Hubble in particular is valuable for this research, these astronomers said; Hubble is sensitive to radiation from hydrogen, and it has measured hydrogen radiation from 20 different K-type dwarf stars.
Comparison of M, K and G stars in terms of habitable zone, X-ray irradiance, relative abundance, and longevity. New research supports the idea that K stars are the most friendly for habitable planets.
The research suggests that these types of stars are the most likely to have habitable planets. They are slightly smaller and cooler than our sun, which is a G dwarf star. It’s easy to think, of course, that sunlike stars would be the most ideal, but that might not be the case, after all. As Guinan explained in a statement:
K dwarf stars are in the ‘sweet spot,’ with properties intermediate between the rarer, more luminous, but shorter-lived solar-type stars (G stars) and the more numerous red dwarf stars (M stars). The K stars, especially the warmer ones, have the best of all worlds. If you are looking for planets with habitability, the abundance of K stars pumps up your chances of finding life.
This is encouraging news for those hoping to find extraterrestrial life, since there are about three times as many K dwarf stars in our galaxy as there are sunlike stars. Some of them are fairly close by, as well, with about 1,000 of them within 100 light-years. That’s close enough for any planets orbiting them to be studied by telescopes.
These stars also live a lot longer than our sun will, from 15 billion to 45 billion years. That provides a much longer time period for evolution, as compared to our sun, which is already halfway through its lifetime of 10 billion years. Guinan said:
Solar-type stars limit how long a planet’s atmosphere can remain stable.

What about red dwarfs? They are the most abundant type of stars, and have even longer lifetimes, but they are very violent places for planets. The X-ray and ultraviolet (UV) radiation from red dwarfs, or M dwarfs, can be up to hundreds of thousands of times more intense than what Earth receives from its sun. Even planets in the habitable zone could have their atmospheres stripped away. Needless to say, not the most ideal location for life to evolve, at least advanced forms of life, as Guinan noted:
We’re not so optimistic anymore about the chances of finding advanced life around many M stars.
K dwarfs, on the other hand, are much less active and hostile, with lower levels of radiation. During the same period of time as the lifetime of our sun, about 10 billion years, they only increase in brightness from about 10-15%. This, with their already longer lifetimes, gives evolution much more time to evolve into higher lifeforms.
Kepler-442 is noteworthy in that this star (spectral classification, K5) hosts what is considered one of the best Goldilocks planets, Kepler-442b, a rocky planet that is a little more than twice Earth’s mass. So the Kepler-442 system is a Goldilocks planet hosted by a Goldilocks star!
Artist’s concept of the view from one of the seven known planets in the TRAPPIST-1 red dwarf star system . Red dwarfs are very common, but hostile to planets orbiting them.
Tau Ceti and Epsilon Eridani were also targets for Project Ozma in 1960, the first attempt to detect radio signals coming from advanced alien civilizations. That search came up empty, but based on the new research and what we have learned about these kinds of stars since then, these stars may yet turn out to have habitable planets.
An earlier study from last year by researchers at NASA’s Goddard Space Flight Center had also come to the conclusion that K dwarf stars would be the most likely to have habitable planets. According to Giada Arney at Goddard:
I like to think that K stars are in a ‘sweet spot’ between Sun-analog stars and M stars. I find that certain nearby K stars like 61 Cyg A/B, Epsilon Indi, Groombridge 1618, and HD 156026 [part of the 36 Ophiuchi system] may be particularly good targets for future biosignature searches.
Edward Guinan of Villanova University, who led the new project.
Over 4,000 exoplanets have been confirmed so far orbiting distant stars, and some of those are in K dwarf star systems. With K dwarfs being so abundant, and with the ever-increasing numbers of Earth-sized worlds being found, including in habitable zones, it would seem to be only a matter of time before a truly habitable planet is discovered. And perhaps, not only habitable, but actually home to some form of life, whether it be intelligent aliens or microbes.
Bottom line: New research shows that Goldilocks stars – K dwarfs, or orange dwarfs – are the most likely to have planets that can support life.

The aquatic system of the Budj Bim Cultural Landscape – an elaborate series of stone-lined channels and pools crafted by ancient indigenous people in Australia - has long been known to archaeologists, and was finally added to UNESCO's World Heritage List in July 2019.

Raging bushfires in Australia have revealed extra sections of an ancient aquaculture system built by indigenous people in south-west Victoria, Australia thousands of years ago.
The fires, that started back in December and were brought under control only recently, ripped through the state, burning away the thick vegetation in the area to lay bare the remarkable discovery.

The Budj Bim Cultural Landscape, consisting of extensive water channels and dams built by indigenous Australians from volcanic rocks to trap and harvest eels for food, is one of the world's most extensive and oldest aquaculture systems.
Gunditjmara representative Denis Rose, project manager at the non-profit group Gunditj Mirring Traditional Owners Aboriginal Corporation said the recent discovery revealed the system was significantly larger than previously recorded.
"When we returned to the area, we found a channel hidden in the grass and other vegetation. It was about 25 meters (82 feet) in length, which was a fairly substantial size," Rose told CNN.
According to the official, new structures were now distinctly seen in the burnt landscape, resembling channels and ponds.
"It was a surprise continually finding new ones that the fires revealed," he said.
Initially, the fire in the vicinity of the national park was caused by a lightning strike in late December. Spreading rapidly, it engulfed an area of around 790 hectares (3 square miles), according to Mark Mellington, district manager for Forest Fire Management Victoria.
Firefighters and local groups, he said, had joined efforts to identify culturally important sites and use "low impact techniques" to replace heavy machinery when dousing the flames.

The bushfires in this area did not cause the same level of devastation as in other parts of Australia, and locals hope now they will make ample use of this opportunity to further explore the ancient aquaculture system.
"Over the next few weeks, we are hoping to conduct a comprehensive cultural heritage survey to check areas that were not previously recorded. It's important because it provided a rich, sustainable life for the traditional people, and has continued to be an important part of our cultural life," said the Gunditjmara representative.
The aquatic system at Budj Bim has long been known to archaeologists, and was added to UNESCO's World Heritage List last July. Constructed by the Gunditjmara people more than 6,600 years ago, it is believed to be older than Egypt's pyramids

Well worth the trip to Heywood- Gunditjmara land. World heritage eel traps, homes and the remains of Lake Condah mission. Braydon is a national treasure. #budjbim
Budj Bim or Mount Eccles is an extinct volcano near Macarthur in southwestern Victoria, Australia. The Gunditjmara name, Budj Bim, translates as “High Head”.
The peak is a scoria hill that was thrown up near a group of three overlapping volcanic craters that now contain Lake Surprise.
The Budj Bim lava flows provided the basis for the complex system of channels and dams developed by the Gunditjmara in order to trap, store and harvest kooyang (short-finned eel – Anguilla australis) from Lake Condah.
This aquaculture system provided an economic and social base for Gunditjmara society for six millennia, believe scientists. Initially with a population believed to be in the thousands, the Gunditjmara was one of several indigenous groups of people that used to reside in the southern parts of the present-day Victoria state before the European settlement.
Budj Bim is believed to convincingly uproot the myth that all indigenous people were nomadic and not agriculturally inclined.
"The Budj Bim Cultural Landscape bears an exceptional testimony to the cultural traditions, knowledge, practices and ingenuity of the Gunditjmara," says the UNESCO World Heritage Centre site.

Bosbranden Australië leggen bouwwerken ouder dan de piramides bloot. Maar wat zijn het?
Het Budj Bim-landschap in het zuidwesten van Australië, dat vorig jaar op de Werelderfgoedlijst is gezet, is een groot natuurgebied bestaande uit kanalen, vulkaangebieden en moerassen.
Het gebied was 6000 jaar lang een belangrijke plek voor de Aboriginals.
Door de verwoestende bosbranden zijn bouwwerken onthuld die duizenden jaren geleden in het gebied zijn neergezet door de inheemse bevolking.
Aanzienlijk groter
Door de hevige branden verdween de dichte begroeiing en kwamen de opmerkelijke bouwwerken bloot te liggen.
Het Budj Bim-landschap bestaat uit een systeem van kanalen en dammen die door de Aboriginals zijn aangelegd met behulp van vulkanisch gesteente.
Dit systeem blijkt nu aanzienlijk groter te zijn dan altijd is gedacht.
Ouder dan de Egyptische piramides
Het is ruim 6600 jaar geleden aangelegd door het Gunditjmara-volk en zou daarmee ouder zijn dan de Egyptische piramides.
Het complexe systeem van kanalen en dammen is door de Gunditjmara ontworpen om alen te vangen die uit een nabijgelegen meer afkomstig waren.
“Toen we terugkeerden naar het gebied ontdekten we een verborgen kanaal in het gras met een lengte van 25 meter,” zei projectmanager Denis Rose tegen CNN.
Verrassing
Onderzoekers hebben in het verbrande landschap meerdere nieuwe bouwwerken ontdekt, die lijken op kanalen en vijvers.
“Het was een verrassing om steeds weer nieuwe [bouwwerken] te ontdekken die door de branden zijn blootgelegd,” zei Rose.
De bosbranden in dit deel van Australië zijn eind december vorig jaar ontstaan als gevolg van blikseminslag.
“Anybody else see this tonight? The sky was flashing pink and purple – super bright. Thought it might be lightning, but it’s fairly cold (40 degrees), and there was no thunder.”
Well, that certainly sounds strange and the witness has a video from his doorbell camera – the 2020’s replacement for the dash cam, Google Maps and security cameras for capturing strange phenomena. (Watch it here.) One would think that giving it broad media coverage would quickly identify the source of these flashing lights in the sky over Bethel, Ohio. Weather anomaly? Fireworks? Transformer explosions? Meteor? Military? Aliens? Yet it’s been over a week and no one has solved the mystery of the flashing lights of Bethel.
“The first thing that came to mind was what just happened with Iran, and I thought it might be a nuclear explosion. It was that bright and that powerful. I was in the Army and it reminded me of phosphorescent flares we used that light up the whole sky.”
Tim Walker and his daughter Carolyn Walker saw the flashes on the evening of January 12. Walker got the video from Ring.com and posted it on Facebook, where it was picked up by multiple media sites. Over a week later, the comments on the video are still speculative with no confirmed cause. Another witness, Charles Rogers, sent his video to local station FOX19 NOW, which contacted all of the usual suspects and experts.
“We contacted Clermont County Emergency Management. They have no explanation but did hear from plenty of people reporting the flash. Bethel Police had the same response. We also reached out to Duke Energy. According to them, 584 customers lost power for two minutes just before 7 p.m. Sunday. Crews drove that line Monday and found no issues. We also asked an astronomer if this could be a meteor. He says no because a meteor would flash above the clouds rather than below. As for lightning, the nearest strike was hundreds of miles away.”
That was the latest from them as of January 14. On January 20, the Lexington Herald-Leader picked up a story by Mark Price of the Charlotte Observer, who asked Walker if the flashes had been identified. Walker said they hadn’t. Other witnesses have posted on his Facebook page, but no confirmed explanations. Price had no answers either.
“I’ve done a lot of reporting on UFOs and other strange phenomenon, and this is really the strangest light show I’ve ever seen caught on video.”
It’s too bad David Letterman is no longer doing his show with the popular segment, “Is this anything?” Bandleader Paul Schaefer always had interesting, speculative comments on the strange things Dave would show him. That seems to be better than asking government agencies or local authorities these days, as the fine folks in Colorado, Nebraska and Wyoming are finding out with the mysterious drone formations they’ve received no answers on despite their presence in the night sky since before Christmas.
Which brings us back to Tim Walker’s first reaction when he saw the lights over Bethel, a small village east of Cincinnati near the Kentucky border.
“The first thing that came to mind was what just happened with Iran.”
There’s no doubt Walker was in the majority in having that first reaction … one that the people in Colorado have while watching their own mysterious things in the sky.
Perhaps it’s time to accept the obvious … getting no answer is now the new norm.
The mysterious giant drones that have been flying in formation over parts of Colorado, Nebraska and Wyoming just got a possible explanation … and it may create more mysteries than it solves … if it solves any. A member of a group of amateur UFO trackers claims they’ve been flying drones in formation over Colorado in an organized search for the “unidentified aerial phenomenon” that has become known as the Tic Tac UFOs. Yes, the ones seen by USS Nimitz pilots in 2004 on the east coast. What are they doing in Colorado, you ask? Let’s find out.
“If there was any interference with any other aircraft, that absolutely was not ours.”
In what appears to be an exclusive report by the Sterling Journal-Advocate (Sterling is in far northeastern Colorado where many of the drone sightings have occurred), Michael Spicer of Durango (a long way from Sterling in far southwest Colorado) takes an obviously defensive position as he talks the drone formations he and his group have been flying in and around Sterling. Spicer says the group is known as ArchAngleRECON and they’re headquartered in Wichita, Kansas – almost 500 miles from Sterling. He admits the group has been flying groups of 6 to 12 drones along longitude and latitude lines in northeast Colorado – the “grid pattern” many witnesses have described. Of course, he didn’t think they were doing anything wrong. Until …
“Spicer said the group was unaware of the stir caused by drones until he was contacted recently by the Federal Aviation Administration. He said he was interviewed by special Agent Michael Bumberger of the FAA’s Investigations and Law Enforcement Assistance Program. He said none of ArchAngelRECON’s drones were ever flown anywhere near any airport, and they did not encounter any other civilian aircraft.”
That was probably as part of the multi-government-agency investigation that ended recently with the “no harm, no foul” conclusion that they still don’t know whose drones they are, but they’re not illegal, so go back to what you were doing and forget about them. Despite that, Spicer seemed shaken by the contact and was probably questioned about reports that a drone may have interfered with a hospital helicopter and others were seen over Sterling Municipal Airport – an obvious FAA violation.
Before you ask, there’s not much info about ArchAngelRECON. There’s a 75th ArchAngel Recon “Multi game clan” with some videos on YouTube, but they’re related to gaming, not drones or UFOs. As usual these days, Spicer claims the group is tracking the new technology aircraft which is what the infamous Tic Tac UFOs from the 2004 incident are suspected by many of being. However, he’s quick to point out that not all of the drones seen recently belong to his group. He doesn’t say how many are and the report is pretty empty of any additional investigative evidence. Spicer also gives no information on whether they saw any of the drones/Tic Tacs.
It’s almost as if “looking for Tic Tac UFOs” is the new cover for any nefarious activities, and heading to Colorado to hunt the drones is becoming this year’s “Storm Area 51.” Will ‘Storm Sterling’ solve the mystery or end up in a failed rock concert too?
“That absolutely was not ours.”
OK, Michael Spicer, we’re not blaming you for that. In fact, you’re not the first to connect the drones to the Tic Tac. That honor belongs unofficially to Mike Turber, the investigative journalist and cybersecurity expert who made the link earlier this week.
So, despite the government’s plea to “move along, nothing to see here,” the Colorado/Nebraska/Wyoming/??? Drone mystery isn’t going away.
Have You Ever Seen Someone Showing Unidentified Flying Objects In Their Videos?
Have You Ever Seen Someone Showing Unidentified Flying Objects In Their Videos?
With the recent explosion of UFO footage in recent years, many people wonder if it is possible to identify a UFO in someone’s video. You may be able to tell the difference between your own UFO and the strange lights in someone’s video, but what do you think a “Truther” might do if they could find your video? Would they tell everyone on the internet that you are a professional con man?
We have all heard the stories of deception in the past and will continue to do so, especially when we hear information about things that are not real, and people getting fooled by these people. I guess you could say that a UFO is like the golden goose in the movie The Wizard of Oz, if you think about it; a hoax is just like a hoax, however, if you could disprove something that people claim is real you could convince the masses of its fakery.
Of course, the only way you can do this is to make a person think that you have proof that someone else has proven something to them. Now, if the skeptics like yourself had something, like videos of UFOs, then you could definitely convince some of the skeptics. But, you do not, so how do you proceed?
If you are the guy that says, “Look at my photos!” then I would recommend that you hold off on making any videos until you get someone to believe you. You see, I have to put the picture of this subject out there, in order for people to believe what I have to say, if they can prove something to me, then I will have no need for them.
If you can prove that people have been seen in the photos, then you will have convinced more people than you know that the UFO phenomenon is real, but, it is probably not, that’s why they all go to the movies to see alien aliens. Some have pointed out to me that since UFOs are just that; they could justbe pictures of old mountain ranges or clouds.
Then again, maybe these are not real, and a more reliable source of UFOs is a web site with videos. If you are sure that these UFO videos are real, then the last thing that I would want to do is to convince anyone of the reality of aliens.
So you see, you do not have to be so sure. If you cannot find any evidence, then simply say that they are in the same category as the pictures you see in your mind’s eye, no one needs to know!
