Archaeologists find 12,000-year-old pictograph at Gobeklitepe
Archaeologists find 12,000-year-old pictograph at Gobeklitepe
Excavations being conducted at the ancient city of Göbeklitepe in Turkey have uncovered an ancient pictograph on an obelisk which researchers say could be the earliest known pictograph ever discovered.
A pictograph is an image that conveys meaning through its resemblance to a physical object. Such images are most commonly found in pictographic writing, such as hieroglyphics or other characters used by ancient Sumerian and Chinese civilizations. Some non-literate cultures in parts of Africa, South America and Oceania still use them.
“The scene on the obelisk unearthed in Göbeklitepe could be construed as the first pictograph because it depicts an event thematically” explained Director of the Şanlıurfa Museum, Müslüm Ercan, to the Hurriyet Daily News . Ercan is leading the excavation at Göbeklitepe. “It depicts a human head in the wing of a vulture and a headless human body under the stela. There are various figures like cranes and scorpions around this figure. This is the portrayal of a moment; it could be the first example of pictograph. They are not random figures. We see this type of thing portrayal on the walls in 6,000-5,000 B.C. in Çatalhöyük [in modern-day western Turkey].”

The artifacts discovered in the ancient city have provided information about ancient burial traditions in the area in which bodies were left in the open for raptors such as vultures to consume. According to Mr Ercan, this enabled the soul of the deceased to be carried into the sky. It was called “burial in the sky” and was depicted on the obelisks in Göbeklitepe. Such rituals were conducted in and around the city around 12,000 years ago. Many of the items discovered on the site have not been seen before anywhere else in the world and thus are the first of their kind to be discovered.
Göbeklitepe is situated on the top of a hill about 15 kilometres away from Sanliurfa in South-eastern Turkey. The city can be dated back to 10,000 BC and consists of a series of circular and oval shaped structures that were first excavated by Professor Klaus Schmidt supported by the German Archaeological Institute. Schmidt travelled to the site having heard about it from accounts of other previous visits by anthropologists from the University of Chicago and Istanbul University in the 1960’s. Both institutions ignored the site, believing it to be nothing more than a medieval graveyard.
Artifacts found on the site indicate that the city was intended for ritual use only and not as a domain for human occupation. Each of the 20 structures consists of a ring of walls surrounding two T-shaped monumental pillars between 3 metres (9 feet) and 6 metres high (19 feet) and weighing between 40 and 60 tons.

Archaeologists believe these pillars are stylised representations of human beings because of the human appendages carved into the stone. These images are accompanied by those of animals including foxes, snakes, wild boars, cranes and ducks.
The archaeologists believe Göbeklitepe was used as a religious centre. Geo-radar work has revealed evidence of 23 temple structures in the area. Two of the obelisks in the city were constructed in the form of a letter T and are positioned opposite each other within a circle of smaller, round obelisks.
Ercan said that the museum at Şanlıurfa contains a small sculpture of a pig that was discovered in front of the central stelas in the ‘C’ temple at Göbeklitepe. Such statues may have depicted sacred beings.
Work on the basic infrastructure of a roof to cover the site and help preserve its structures and artefacts has just been completed, ready for the construction of the roof itself. This is an EU project and the archaeologists aim to complete it in eight months’ time.

You might be aware of one of Uranus' complexities: It spins on its side, and its moons orbit on that same rotated plane. New evidence strengthens the case that Uranus was smashed in a giant collision, resulting in its sideways orientation to its orbital plane and perhaps explaining some of the planet's other mysteries.
A new paper performs a series of simulations on Uranus early in its history, taking note of what an early impact may have done to its rotation rate, atmosphere and internal structure. The impact could have left a clear signature still visible inside the planet we see today.
Uranus really is strange. Not only does it rotate on an axis that sits at a 98-degree angle to its orbital plane, but, unlike the other giant planets, it doesn't appear to release more heat than it receives from the Sun. Its magnetic field, too, appears warped compared to the Earth's.
An impact could perhaps help explain some of these strange traits.
Scientists have been simulating giant impacts into Uranus since the early 1990s, according to the new paper published in the Astrophysical Journal.
This time around, researchers built a new simulation with the newest and best available data of the planet's composition. This allowed them to model how a giant impactor, perhaps one to three times the mass of Earth, would have deposited "material and energy inside Uranus", and how much debris would be left over from which moons could form.
"This study provides some great new insights into what might have happened all those billions of years ago, with material left over from the impact possibly even serving to trap some of that heat inside," Leigh Fletcher, Royal Society Research Fellow at the University of Leicester, told Gizmodo.
But this is just a simulation, and like we always say: All models are flawed, but some are interesting. Models can't tell us exactly what happened; it will take a lot more data to fully understand Uranus' story.
"Of course, what we really need next is an ambitious robotic mission to explore Uranus and its diverse satellite system," said Fletcher. "Gravitational, atmospheric, and magnetic field mapping, following what we've done at Jupiter with Juno, and at Saturn with Cassini, could provide some new clues to better constrain these models, by unlocking the secrets of an ice giant interior for the first time."
Uranus is truly a mystery. Will humans finally take up the task to explore it?
Symmetrical streaks in Venus' lower-level clouds as seen by the Akatsuki spacecraft (left) and reconstructed through simulation. A strong downflow is denoted by brighter parts of the images.
Surprise! New pictures show two symmetrical streaks hiding in the sulfuric acid clouds close to the surface of Venus.
The Japanese Akatsuki spacecraft spotted the twin phenomena in Venus' northern and southern hemispheres. Each streak is roughly 6,200 miles (10,000 kilometers) across. That's more than double the distance between San Francisco and New York City.
Venus is close to Earth's size but orbits closer to the sun than our home does. Venus isn't habitable by life as we know it, not by any stretch of the imagination. Its atmosphere is mostly carbon dioxide. It has clouds made of sulfuric acid. The planet is, in fact, fully enveloped in clouds, and you cannot see its surface with the naked eye. Underneath the clouds lies a world shaped by the runaway greenhouse effect and featuring oven-like temperatures, possible active volcanoes and bone-crushing pressures.
This is all old news to researchers — after all,Soviet Union landersbriefly survived this surface environment in the 1970s and 1980s — but the streaks were previously unknown. And they may be unique to Venus.
The story of their formation isn't too alien, though: The streaks are related to polar jet streams, researchers from Japan's Kobe University, which led the study, said in a statement. Polar jet streams are found on Earth, but their results are different on Venus.
At Earth's mid and high latitudes, dynamic winds can form cyclones, high-pressure systems and jet streams — and the same thing is probably happening at the high latitude of Venus, the university's analysis shows. But at lower latitudes on Venus, things get a little weird. Large-scale flows in the Venus atmosphere, coupled with that world's planetary rotation, create huge vortexes starting at the equator and stretching as far as 60 degrees latitude north and south. On Earth, the equivalent vortex would stretch well into Canada in the north — and as far south as the ocean near Antarctica.
"When jet streams are added to this phenomenon, the vortexes tilt and stretch, and the convergence zone between the north and south winds forms as a streak," researchers said in the statement. "The north-south wind that is pushed out by the convergence zone becomes a strong downward flow, resulting in the planetary-scale streak structure." Planetary rotation and atmospheric fluctuations over the equator keep the hemispheres symmetrical.
Akatsuki captured the streaks using an infrared camera that can measure wavelengths of 2 micrometers (a tiny fraction of a millimeter). This allows the spacecraft to spy on the construction of lower cloud banks only 31 miles (50 km) from the surface. Researchers modeled the atmosphere using a program called AFES-Venus, developed before Akatsuki arrived at Venus in 2015. (The probe was supposed to get there in 2010 but missed the opportunity; the second attempt worked.)
The researchers noted that it is difficult to observe Venus' surface and lower atmosphere, which could affect the accuracy of the simulations.
A study based on the research was published Jan. 9 in the journal Nature Communications. The research was led by Hiroki Kashimura, a project assistant professor at Kobe.
This Ancient Map Challenges The Entire Human History
This Ancient Map Challenges The Entire Human History
The map of Piri Reis, which was made circa 1520, achieved a level of detail of American geography, which according to experts, would only be achievable using aerial photographs. This incredible map challenges every single thing we know about our past, yet history books have completely omitted this incredible ancient document.
There are a number of archeological discoveries that question our past, this is the case of the map which was found in 1929, during the restoration of the Topkapi palace in Istanbul Turkey, which describes in high detail the geography of the American Continent with such a precision that it looks as if it was put together with the aid of aerial photography. However, the map was made at a time when mainstream history tells us there were no flying vehicles on Earth and mankind’s technology was very limited. The map composed by Ottoman admiral Piri Ibn Haji Muhiddin Memmed, aka Piri Reis is in fact part of maritime navigation collection called Bahriye which is basically composed of 210 partial maps, dated around 1513 and 1528.
The perfection and details displayed on the map have been the subject of debate for years among scholars who cannot understand nor explain how this map even exists. Today, numerous enigmas remain about the Piri Reis map, especially in regards to Latin America and the Southern regions of our planet.
This Turkish Admiral did not only draw the outline of the nearly unexplored South American region, detailing rivers, mountains and lakes that were believed to be unknown at that time in history, but he managed to accurately depict the geography of Antarctica, a continent that wasn’t officially investigated until the twentieth century…
As a matter of a fact, the first exploratory navigation in search of Antarctica was led by British explorer James Cook, who launched the journey in 1772 and only managed to see snow and ice, 250 years after Pirir Reis had already drawn Antarctica on navigational charts. It wasn’t until 1819, when Fabián von Bellingshausen discovered the landmass of Antarctica for the first time, and it was in 1950 when American expedition Deep Freeze managed to “reveal” the geography of Antarctica.
So, how is it possible that Pirir Reis managed to accurately draw the geographical details of Antarctica in 1513? With details that were not discovered until 1952? But that isn’t even the most interesting part of the Piri Reis Map. Inexplicably, the Piri Reis map depicts Antarctica without Ice, yet the Antarctica has been frozen for at least 6000 years. How is it possible that Piri Reis drew Antarctica without Ice? Where did he obtain this level of details? No one has been able to answer the mysteries surrounding this enigmatic ancient map.
The only thing we can conclude is that, somehow, someone knew how our planet looked like thousands of years ago from the air… and the Turkish Admiral managed to obtain this information and create the most enigmatic map we have discovered to date, a map that challenges history as never before.
The Seventh Moon of Neptune Is Broken, it "Shouldn't Be There" Say Astronomers
Astronomers call it “the moon that shouldn’t be there.”
After several years of analysis, a team of planetary scientists using NASA’s Hubble Space Telescope has at last come up with an explanation for a mysterious moon around Neptune that they discovered with Hubble in 2013.
The tiny moon, named Hippocamp, is unusually close to a much larger Neptunian moon called Proteus. Normally, a moon like Proteus should have gravitationally swept aside or swallowed the smaller moon while clearing out its orbital path.
So why does the tiny moon exist? Hippocamp is likely a chipped-off piece of the larger moon that resulted from a collision with a comet billions of years ago. The diminutive moon, only 20 miles (about 34 kilometers) across, is 1/1000th the mass of Proteus (which is 260 miles [about 418 kilometers] across).
This is an artist’s concept of the tiny moon Hippocamp that was discovered by the Hubble Space Telescope in 2013. Only 20 miles across, it may actually be a broken-off fragment from a much larger neighboring moon, Proteus, seen as a smaller crescent in the upper right. This is the first evidence for a moon being an offshoot from a comet collision with a much larger parent body.

“The first thing we realized was that you wouldn’t expect to find such a tiny moon right next to Neptune’s biggest inner moon,” said Mark Showalter of the SETI Institute in Mountain View, California. “In the distant past, given the slow migration outward of the larger moon, Proteus was once where Hippocamp is now.”
This scenario is supported by Voyager 2 images from 1989 that show a large impact crater on Proteus, almost large enough to have shattered the moon. “In 1989, we thought the crater was the end of the story,” said Showalter. “With Hubble, now we know that a little piece of Proteus got left behind and we see it today as Hippocamp.” The orbits of the two moons are now 7,500 miles (about 12,070 kilometers) apart.
Neptune’s satellite system has a violent and tortured history. Many billions of years ago, Neptune captured the large moon Triton from the Kuiper Belt, a large region of icy and rocky objects beyond the orbit of Neptune. Triton’s gravity would have torn up Neptune’s original satellite system. Triton settled into a circular orbit and the debris from shattered Neptunian moons re-coalesced into a second generation of natural satellites. However, comet bombardment continued to tear things up, leading to the birth of Hippocamp, which might be considered a third-generation satellite.
“Based on estimates of comet populations, we know that other moons in the outer solar system have been hit by comets, smashed apart, and re-accreted multiple times,” noted Jack Lissauer of NASA’s Ames Research Center in California’s Silicon Valley, a coauthor on the new research. “This pair of satellites provides a dramatic illustration that moons are sometimes broken apart by comets.”
Hippocamp is a half-horse half-fish from Greek mythology. The scientific name for the seahorse is Hippocampus, also the name of an important part of the human brain. The rules of the International Astronomical Union require that the moons of Neptune are named after Greek and Roman mythology of the undersea world.
The team of astronomers in this study consists of M. Showalter (SETI Institute, Mountain View, California), I. de Pater (University of California, Berkeley, California), J. Lissauer (NASA Ames Research Center, Silicon Valley, California) and R. French (SETI Institute, Mountain View, California).
The paper will appear in the February 21 issue of the science journal Nature.

David Wilcock: Antarctica Stunning New Insiders! via Linda Moulten Howe
Linda Moulton Howe has just shocked the UFO community with two NEW insiders who report on ancient ruins in Antarctica, a modern-day secret space program and interactions with at least seven ET races. This is the biggest new development in the insider community since Emery Smith came forward.
Both whistleblowers are high-level military who have been fully vetted out, showing documentation. David Wilcock only found out about this yesterday and has already been in communication with Linda about it and watched all of her videos. Hear his initial reactions to this stunning new testimony!
We will review the material that has been disseminated in the first two of six planned live broadcasts on Linda’s own YouTube channel, Earthfiles. The confirmations with our material are literally stunning.

Op de bodem van het Fuxian-meer bevindt zich een piramidestad die ouder is dan het meer zelf. Door wie is deze stad gebouwd?
Volgens sommige theoretici is het meest overtuigende bewijs voor buitenaards bezoek te vinden in China, het land van de vier grote uitvindingen: papier, boekdrukkunst, buskruit en het kompas.
Nieuw bewijs dat is gevonden in het land van de Grote Muur suggereert dat zich in een ver verleden aliens onder ons bevonden en dat ze ook nu nog onder ons zijn.
Maya’s
In een meer in de Chinese zuidelijke provincie Yunnan hebben onderzoekers enkele jaren geleden drie bouwwerken gevonden die lijken op de piramides die de Maya’s in Amerika bouwden, zo meldde de Chinese radio.
De archeologen troffen ze aan op de bodem van het Fuxian-meer, het op één na diepste meer van China.
Het complex van bouwwerken beslaat in totaal 2,4 vierkante kilometer en telt acht prominente bouwwerken, waarvan er drie sterk op piramides lijken die in Midden- en Zuid-Amerika voorkomen.
Nog veel meer
De onderzoekers denken dat de overblijfselen 2000 jaar oud zijn. Ze denken nog veel meer in het meer aan te zullen treffen, want alles wijst erop dat er ruïnes van een hele stad onder het wateroppervlak liggen.
Volgens sommige theoretici was de verzonken stad vroeger een buitenaardse basis.
“Gezegd wordt dat de piramides net zo oud zijn als de Egyptische piramides en misschien nog wel hoger,” zegt schrijver Paul Stonehill. “Dit is een ongelooflijke ontdekking.”
A species of giant tortoise believed to have gone extinct more than 100 years ago has been spotted in the Galapagos Islands.
Ecuador's environment minister Marcelo Mata made the announcement that an adult female Fernandina Giant Tortoise had been discovered.
Many species of giant tortoises were over-hunted for their meat by European and other colonists who travelled to the Galapagos archipelago.
Scroll down for video
A specimen of the giant Galapagos tortoise Chelonoidis phantasticus, thought to have gone extint about a century ago, is seen at the Galapagos National Park on Santa Cruz Island in the Galapagos Archipelago (pictured)
An adult female female Fernandina Giant Tortoise (Chelonoidis phantasticus) was discovered by members of the Galapagos National Park and the US NGO Galapagos Conservancy (pictured)
The sighting came during an expedition to the island of Fernandina in the western Ecuadorian region of the archipelago funded by Animal Planet for an upcoming documentary series titled 'Extinct or Alive'.
Expedition leader Forrest Galante crossed a three mile stretch of hardened lava flow and found the animal buried deep under a pile of brush.
'As a biologist and someone who has dedicated my life to the pursuit of animals believed extinct, this is by far my greatest scientific accomplishment and proudest moment,' said Mr Galante.
'Much like Lonesome George was an icon of extinction, I believe she can become an icon of wildlife hope. She's the rarest tortoise, if not animal, in the entire world and one of the largest discoveries in the Galapagos in the last century.'
Extinction looms large for the animal and its largest existential threat is considered to be volcanic activity and lava.
It is the youngest and most volcanically active of all the Galapagos islands.
The tortoise was found by members of the Galapagos National Park and the US NGO Galapagos Conservancy.
The Fernandina Giant Tortoise is one of 14 giant tortoise species in the Galapagos but only ten are thought to have survived human colonisation and over-hunting for food.
The female has a large body, smooth shell and a pink head but no other details have been revealed.
Susanna Dinnage, Global President of Animal Planet added: 'We are moved and excited about this historic news.
'As the rate of animal extinction is widely debated, it gives us great hope that some species are surviving against the odds and that at Animal Planet we can do our bit to celebrate and support them.'
A tweet from Mr Mata included an image of the reptile and the only other known specimen was collected in 1906.
A spokesman for Galapagos Conservancy said: 'While thought to be extinct due to volcanic eruptions in past centuries, there have been anecdotal observations indicating that there may indeed still be a very few left on the island.'
Anecdotal evidence and unconfirmed sightings have been reported ever since but it was formally listed on the IUCN red list as 'critically endangered (possibly extinct)'.
Surveys and expeditions have turned up evidence of scat previously.
'These sightings and signs, though needing verification through more extensive surveys, indicate the possibility that the species may remain extant in exceedingly small numbers,' IUCN said.
No other details have been revealed about the rediscovery of the species long-thought to be extinct. The female has a large body, smooth shell and a pink head

In 2015, Ecuador announced the discovery of a new species of tortoise on another island in the Galapagos, called Santa Cruz.
It was named Chelonoidis donfaustoi in honour of Fausto Llerena who took care of 'Lonesome George', a male Pinta Island tortoise (Chelonoidis abingdonii) and the last known individual of its species.
Lonesome George died in 2012 and scientists believe that tortoises first arrived in the Galapagos two to three million years ago after drifting 600 miles from the South American coast on vegetation rafts.
They were already large reptiles before arriving on the Islands.
Charles Darwin visited the Galapagos for five weeks on his second voyage and they appeared in his writings, playing a key role in the development of the theory of evolution.
He observed different finches on different islands but theorised they had evolved from the same species.
Differences in beak size and shape married up with the available food sources on the respective islands, birthing the theory of natural selection.
WHAT IS THE ENDANGERED 'RED LIST'?
Species on the endangered red list are animals of the highest conservation priority that need 'urgent action' to save.
An Amber list is reserved for the next most critical group, followed by a green list.
Red list criteria:
Globally threatened
Historical population decline in UK during 1800–1995
Severe (at least 50 per cent) decline in UK breeding population over last 25 years
Severe (at least 50 per cent) contraction of UK breeding range over last 25 years
Last year, in the UK, several more species were added to the list.
In November, 2018, a Chinese biophysicist named He Jiankui came into the international spotlight after reports that he used the CRISPR gene editing technology to create thefirst genetically modified humans. The genetically modified twins, known by the pseudonyms Lulu and Nana, were born on November 8, 2018, to widespread international condemnation of He’s actions, seen by a large part of the scientific community as reckless tinkering. He Jiankui says the genetic modifications done to the twin baby girls were to make them immune to the HIV virus. How could anyone be mad about that? Well, it turns out that besides HIV immunity, He Jiankui’s tinkering might have “accidentally” given the twins super intelligence, enhancing their cognition, memory, and ability to learn. Accidentally.
According to the MIT Technology Review, the HIV immunity and enhanced intelligence are inseparable from one another. To make Lulu and Nana HIV immune, He used CRISPR to delete a gene known as CCR5. HIV needs the CCR5 gene in infect blood cells. But there’s another interesting part of the CCR5 gene: it’s been known since 2016 that removing the gene from mice enhances their memories. What’s more, people who are naturally lacking CCR5 seem to recover better from strokes and perform better in school. A recent journal article names CCR5 as a “suppressor of memories and synaptic connections.”
CRISPR gene editing technology first came to prominence in 2015.
While there is no evidence yet that this was He Jiankui’s true intentions all along, it does seem awfully suspicious at a time when a new biotechnology race between the U.S. and China seems to be starting up. He Jiankui apparently reached out to other scientists around the world for advice and support, but there is no record of him asking any questions about the link between CCR5 and intelligence. Maybe it’s just a happy accident, after all. But it’s also likely that asking those sorts of questions might get you in a bit of hot water before you have your mad-scientist fun.
It is certain that He Jiankui at least knew about the research on CCR5 and cognition. He addressed it at a conference, dismissing it as needing it “more independent verification.” Questioned again on a separate occasion, He stated that he was against genetic modification for enhancements.
One of the authors of new paper on the link between the CCR5 gene and intelligence, Alcino J. Silva, a neurobiologist at the University of California Los Angeles, doesn’t buy it. When the news of the twins’ birth was announced on November 25, Silva immediately suspected that cognitive enhancement was the true aim of He Jiankui’s experiments:
“I suddenly realized—Oh, holy shit, they are really serious about this bullshit.
My reaction was visceral repulsion and sadness.”
Silva sees these kind of genetic experiments as irresponsible and morally repugnant. While we have evidence of what removing this gene does to mice, we have no idea what it will do to humans and even less of an idea what unchecked genetic tinkering would do to human societies. Silva says:
“Could it be conceivable that at one point in the future we could increase the average IQ of the population? I would not be a scientist if I said no. The work in mice demonstrates the answer may be yes. But mice are not people. We simply don’t know what the consequences will be in mucking around. We are not ready for it yet.”
Regardless of He Jiankui’s intentions, the proverbial cat has exited the proverbial bag, and only time will tell what the results of this “mucking around” will be.

Glowing Orbs Hyper Jump To Island In Norway Turning Night Into Day,Feb 20, 2019 Photos, UFO Sighting News.
Date of sighting: February 20, 2019 Location of sighting: Tromso, Norway Source: MUFON #98719 Strange glowing UFO appeared over the mountains of Norway this week. Its a very secluded part of Norway which is one of its islands. Glowing orbs were seen around the mountain tops, but when they appeared, they appeared in a flash of light, as if they hyper jumped to that location and went to an underground base from there. I have seen such things once when I was in the USAF back in 1989. I see why the guy was alarmed. Seeing these at night might cause a family to believe an alien invasion was taking place. When I saw a similar occurrence in Rapid City, SD it was during the day and about 2-5% of the entire city saw it. Those glowing orbs...they when they move, they have a very powerful glow. Awesome and exciting sighting. Scott C. Waring-Taiwan Eyewitness states:

This UFO shot past on a TV news cast, apparently the newscaster didn't notice it, but an eyewitness watching did. At first I thought it was a rocket launch, but no rockets were launched from Cleveland...ever...so thats out. When I added contrast to the screenshot, a thick UFO disk came into focus. It has not wings, not visible propellers, no lights flashing, its pure UFO.
UFOs don't frequent any city in the world more than the next. They are everywhere, over all cities in the world watching, recording...their fascination with human activity is only second to our own with ourselves...like people watching TV shows, news, reading news, blogs, posts, social forums...to learn more. Same deal. They are curious about us and our primitive culture.

This is the most detailed view of the distant object Ultima Thule. The photo is a processed composite combining nine individual images taken by NASA's New Horizons spacecraft just 6.5 minutes before the spacecraft's closest approach to Ultima Thule on Jan. 1, 2019.
The best-ever photos of Ultima Thule have made it down to Earth, and they heighten the intrigue about the frigid and faraway world.
On New Year's Day, NASA's New Horizons spacecraft zoomed past the 21-mile-long (34 kilometers) Ultima Thule, setting a record for the most distant planetary encounter in history. (Ultima lies about 1 billion miles, or 1.6 billion km, beyond Pluto, which New Horizons flew by in July 2015.)
New Horizons has been beaming flyby data and imagery home to its handlers ever since, and will continue to do so for another 18 months. The early returns have been spectacular, revealing Ultima Thule to be a weird snowman-pancake hybrid with mysterious features, such as a bright "collar' where the body's two lobes meet.

And now we have our best look yet. New flyby photos released today (Feb. 22) show Ultima in even more stunning detail, capturing bright circular features and dark pits, whose origins remain mysterious.
"Whether these features [the pits] are craters produced by impactors, sublimation pits, collapse pits or something entirely different is being debated in our science team," New Horizons Deputy Project Scientist John Spencer, of the Southwest Research Institute (SwRI) in Boulder, Colorado, said in a statement.
The newly released images boast a resolution of about 110 feet (33 meters) per pixel. They're the highest-resolution pictures New Horizons has ever taken, and may ever take during its operational life, mission team members said.
The photos were captured just 6.5 minutes before the craft's closest approach on Jan. 1. At the time, New Horizons was 4,109 miles (6,628 km) from Ultima Thule and 4.1 billion miles (6.6 billion km) from Earth, mission team members said. (Closest approach brought the probe within a mere 2,200 miles, or 3,500 km, of Ultima.)
There was no guarantee we'd ever get to see Ultima Thule — whose official name is 2014 MU69 — in this dazzling light. Capturing the newly released images was a "stretch goal" that demanded a precise square-up of Ultima in the narrow field of view of New Horizons' telescopic camera.
"Getting these images required us to know precisely where both tiny Ultima and New Horizons were — moment by moment — as they passed one another at over 32,000 mph [51,500 km/h] in the dim light of the Kuiper Belt, a billion miles beyond Pluto. This was a much tougher observation than anything we had attempted in our 2015 Pluto flyby," New Horizons Principal Investigator Alan Stern, also of SwRI, said in the same statement.
"These 'stretch goal' observations were risky, because there was a real chance we'd only get part or even none of Ultima in the camera's narrow field of view," Stern added. "But the science, operations and navigation teams nailed it, and the result is a field day for our science team! Some of the details we now see on Ultima Thule's surface are unlike any object ever explored before."
New Horizons launched in January 2006 to lift the veil on Pluto, which had remained largely mysterious since its 1930 discovery. The Ultima Thule flyby is the centerpiece of an extended mission that runs through 2021.
New Horizons is in good health and has enough fuel to fly by yet another distant object, if NASA grants another mission extension, Stern and other mission team members have said.

Five Traits That Could Get You "Abducted by Aliens"
Five Traits That Could Get You "Abducted by Aliens"
Research suggests traits could lead to "alien abduction" experiences
Are you worried about being abducted by aliens? I suspect it will cross the mind of some of you reading this post that alien abduction is a possibility. After all, many people worldwide have claimed to have been abducted by aliens, been taken against their will to an alien spacecraft or enclosed place, questioned or physically examined, and they remember these experiences either consciously or through methods such as hypnosis. Indeed, many of those people who claim to be alien abductees are seemingly sincere, psychologically healthy, nonpsychotic people—so are their experiences real and their claims to have been abducted true?
Professor Rich McNally and his colleagues at Harvard University have spent over 10 years researching the psychology of alien abductees, and in particular why it is that some people embrace the identity of “alien abductee." His research has isolated a number of traits possessed by ‘alien abductees’ each of which he argues contributes to the experiences they recall when ‘being abducted’ and to the desire to cling on to their belief that aliens were responsible for their abduction experiences. Let’s look at each of these five traits in turn.
1. Regularly experiencing sleep paralysis and hallucinations when awakening:
Many people who have reported alien abduction suffer episodes of early morning sleep paralysis. On awakening from this paralysis, their terror gives rise to hallucinations of flashing lights and buzzing sounds. Some experience feelings of ‘floating’ around the room or seeing figures in the room. While many people interpret these post-sleep paralysis experiences as dreaming, some people interpret these experiences as seeing figures, ghosts, or aliens.
In an elegant set of experimental studies, McNally and colleagues found that individuals who claimed to have been abducted by aliens were prone to what is known as “false memory syndrome." That is, alien abductees regularly claimed to recall words, items, sentences, etc. in memory tests that they had never actually seen before. If this “false memory” affect can be generalized to autobiographical memories, then individuals who claim to have been abducted by aliens would be twice as likely to “falsely remember” things that had never happened to them than would non-abductees.
3. High levels of “Absorption”:
Alien abductees also score significantly higher than most people on the mental characteristic known as ‘absorption.' This is a trait related to fantasy proneness, vivid imagery, and susceptibility to hypnosis and suggestion. Because of this it is probably not surprising that many alien abductees recall their experiences under hypnosis, where memories of abduction can be induced through suggestibility—especially if the person leading the hypnosis session asks particularly leading questions about abduction.
4. New Age beliefs:
Being whisked up into space ships by tractor beams or light sources is not something that happens every day—nor is it something that is easily explainable within our existing knowledge of physics. Similarly, being subjected to imaginative medical procedures requires a tendency to accept unusual and non-mainstream ideas. This is also a trait possessed by ‘alien abductees.' They score highly on measures of magical ideation and endorse New Age ideas that encompass beliefs about alternative medicines and healing, astrology, and fortune telling. Such beliefs would certainly allow the individual to accept things happening to them that would be dismissed by existing scientific knowledge.
5. A familiarity with the cultural narrative of alien abduction:
As a cultural phenomenon, alien abduction has entered folklore and the images and descriptions of aliens and their spacecraft have become familiar to many people. Alien abductees tend to be very familiar with this cultural narrative which is one possible reason why their descriptions of aliens and their spaceships are so similar—being fuelled as they are by sci-fi films and numerous books about aliens and alien abduction.
As Professor McNally points out in a very readable review of his studies on alien abduction, it is still unclear whether all these characteristics are necessary ingredients in the recipe for ‘alien abduction’ or whether some are more necessary than others. Other researchers have also identified further traits that appear to be characteristic of ‘alien abductees’, such as paranoid thinking and weak sexual identity. There is still much more research to do to fully understand the motivations and thinking patterns of individuals who claim to have been abducted by aliens, but as McNally shrewdly points out, these people are not anxious nor depressed, they are not psychotic and do not appear to have any obvious mental healthproblems. ‘Alien abduction’ experiences often deepen spiritual awareness and give shape to the identities of abductees and provide a basis for their beliefs about the world and the universe. Whether the experiences of abduction were real or not, the experiences and interpretations adopted by ‘alien abductees’ are often psychologically helpful and can be spiritually comforting.
Finally, a note of caution. All of these studies of ‘alien abductees’ were carried out after they had their abduction ‘experiences’, so it’s difficult to know whether these five traits are consequences of the experience or were—as McNally suggests—factors that led individuals to interpret rather earthly experiences (such as sleep paralysis and hallucinations) as evidence of abduction. And then— perhaps fantastically—can we genuinely rule out the possibility that such traits are implanted in their victims by aliens in invasive medical procedures carried out on alien space ships! My skeptical, scientific mind says probably not—but who knows?!

MILIEU Het Halley onderzoeksstation op Antarctica wordt bedreigd door een enorme scheur in het landijs. Een ijsberg die ongeveer acht keer zo groot is als Antwerpen dreigt af te breken.
Voor jaren hield de scheur zich gedeisd, maar in 2013 begon deze opeens te groeien. Wetenschapper Stef Lhermitte bestudeert de scheur, die Chasm 1 genoemd wordt, al jaren en schat dat de scheur nog ongeveer veertig kilometer heeft voordat het afbreekt. De gigantische scheur groeit elk jaar met vier kilometer.
Historisch gezien is de ijsberg van 1.700 km² eigenlijk niet zo groot, maar volgens NASA zou het de grootste ijsberg kunnen zijn die de Brunt-ijsplaat baart sinds de observaties in 1915 begonnen.
Wanneer de ijsberg zich afscheurt, dreigt het Halley onderzoeksstation te verdwijnen. Deze basis bestaat al sinds 1956. Metingen die er gedaan werden, hebben in 1985 onder andere geleid tot de ontdekking van het gat in de ozonlaag.
WETENSCHAP & PLANEET Chinese wetenschappers van de universiteit van Zhejiang in Hangzhou hebben een cyborg-rat ontwikkeld die met behulp van menselijke breinsignalen een ingewikkeld doolhof kan opplossen. Het dier dat elektroden in de hersenen geïmplanteerd kreeg, is deels organisch, deels computer.
In het verleden is al gebleken dat brain-machine interface (BMI) mogelijk is. Dit is een technologie waarbij hersensignalen worden gedigitaliseerd om vervolgens door een computer in acties te worden omgezet. Zo is het bijvoorbeeld mogelijk om afgaande van hersenactiviteit een pijl op een computerscherm naar links of rechts te laten bewegen.
Een volgende stap is om met de hulp van BMI twee verschillende breinen met elkaar te linken (brain-brain interface, of kortweg BBI). In dit onderzoek proberen de wetenschappers het brein van een mens met dat van een cyborg-rat te verbinden.
Elektrodes
Het dier kreeg een aantal elektrodes in de hersenen geïmplanteerd en op zijn rug werd een draadloze micro-stimulator gebonden. Op deze manier kan de mens de bewegingen van de rat sturen.
Uit het onderzoek bleek dat met behulp van de signalen die van het menselijke brein kwamen, de cyborg-rat zich heel vlot door een complex doolhof kon navigeren. Het doolhof is driedimensionaal met allerlei trappen, tunnels en pilaren. De cyborg moest een bepaalde route afleggen binnen de vijf minuten. Daar slaagde het ook in. De wetenschappers zijn dan ook van mening dat hun onderzoek naar het versturen van multidimensionele informatie tussen twee breinen veelbelovend is.

NASA has confirmed that UFO’s have existed throughout mankind’s history
NASA has confirmed that UFO’s have existed throughout mankind’s history
NASA has confirmed that UFO’s have existed throughout mankind’s history – in a bombshell document published on their very own website.
According to the author of a report entitled, ‘Unidentified flying objects in classical antiquity,’ ancient UFO observers described mysterious objects flying in the sky that cannot be attributed to natural phenomena.
A small number of the aerial objects that were described by ancient observers would be their interpretation of natural phenomena, like solar and lunar eclipses, comets, optical phenomena and new stars. However, as the author of the report clearly states, some ancient reports were describing unidentified flying objects that were similar to today’s modern UFO sightings:
My working hypothesis will be that most such reports can be explained by conventional scientific ideas and that, among all the reports, only those that defy reasonable interpretation after full analysis can be said to resemble the most puzzling reports made today.
The ancient UFO witnesses, often described these craft using known “military terminology.”
The military terminology reflects the most advanced technology known at the time, a tendency found also in modern UFO reports, in which a witness gropes for a familiar technical vocabulary—and perhaps a rationalization—to describe an unaccountable phenomenon. That many reports were made during wartime may partially explain the military terminology
The author then lists a number of ancient sightings, that describe “military objects” that were seen in the skies:
• At Rome in the winter of 218 BC “a spectacle of ships (navium) gleamed in the sky” • In 217 BC “at Arpi round shields (parmas) were seen in the sky” • In 212 BC “at Reate a huge stone (saxum) was seen flying about” • In 173 BC “at Lanuvium a spectacle of a great fleet was said to have been seen in the sky” • In 154 BC “at Compsa weapons (arma) appeared flying in the sky” (Obsequens 17). The term refers to defensive weapons, especially shields. In 104 BC “the people of Ameria and Tuder observed weapons in the sky rushing together from east and west, those from the west being routed.” • In 100 BC, probably at Rome, “a round shield (clipeus), burning and emitting sparks, ran across the sky from west to east, at sunset.” • In 43 BC at Rome “a spectacle of defensive and offensive weapons(armorum telorumque species) was seen to rise from the earth to the sky with a clashing noise.” • Historically, the most famous “sky army” appeared in the spring of ca. AD 65 over Judea. The historian Josephus reports:
On the 21st of the month Artemisium, there appeared a miraculous phenomenon, passing belief. Indeed, what I am about to relate would, I imagine, have been deemed a fable, were it not for the narratives of eyewitnesses and the subsequent calamities which deserved to be so signalized. For, before sunset throughout all parts of the country, chariots were seen in the air and armed battalions hurtling through the clouds and encompassing the cities.
The first cluster of reports of fiery globes falls during the Second Punic War. Livy reports that in 217 BC “at Capena two moons rose in the daytime … and at Capua a kind of moon fell during a rainstorm.”
In 168 BC, when L. Aemilius Paullus was waging war against King Perseus of Macedon, “a ball … was the form of a fire that appeared, as large as the moon.”
A more complicated object made its appearance sometime between 151 and 146 BC:
After the death of King Demetrius of Syria, … a little before the Achaean War, a comet blazed out, not inferior to the sun. At first it was a fiery red disk, 17 emitting a light so bright that it dissipated the night. Then, little by little, its size dwindled and its brightness faded; at last the light died completely.
Two parallel records of 91 BC preserved by Livy’s extractors Orosius and Obsequens refer to central Italy. Over the city of Rome “about sunrise a ball of fire shone forth from the northern region with a loud noise in the sky.”
In 74 BC, when a Roman army under L. Licinius Lucullus was about to engage the forces of King Mithridates VI of Pontus, thousands saw a molten silver object falling from the sky.
According to Plutarch:
But presently, … with no apparent change of weather, but all on a sudden, the sky burst asunder, and a huge, flame-like body was seen to fall between the two armies. In shape, it was most like a wine-jar (pithōi), and in color, like molten silver. Both sides were astonished at the sight, and separated. This marvel, as they say, occurred in Phrygia, at a place called Otryae. 23 The presence of thousands of witnesses, including Lucullus and Mithridates, vouches for the incident’s occurrence.
The date was ca. AD 285, in or near the Fayûm in the Egyptian desert. “St. Anthony saw on the desert floor a large silver disk that suddenly vanished like smoke.”
According to Livy, in 214 BC “at Hadria an altar was seen in the sky; around it were forms of men dressed in shining white.”
AD 150. On a sunny day, a “beast” like a piece of pottery (ceramos) about 100 feet in size, multicolored on top and shooting out fiery rays, landed in a dust cloud, accompanied by a “maiden” clad in white.
The author concludes that many ancient observers were describing a very advanced alien technology:
Embedded in the mass of relatively explicable ancient reports, however, is a small set of unexplained (or at least not wholly explained) reports from presumably credible witnesses. If these reports are examined statistically, essential features of what I will, for argument’s sake, call the ancient UFO phenomenon can be extracted:
• shape—discoidal or spheroidal; • color—silvery, golden or red; • texture—metallic or, occasionally, glowing or cloudy; • size—a meter to well over a meter; • sound—usually none reported; • type of motion—hovering, erratic or smooth flight, with a rapid disappearance

The Rosetta space mission revealed a comet as 2 icy balls apparently stuck together billions of years ago. Now scientists say the comet’s double-lobed structure guided its evolution.
Rosetta’s comet – aka 67P/Churyumov-Gerasimenko – as captured in March 2016, when the spacecraft was about 200 miles (329 km) away.
What are the factors that cause a world in space to evolve? In the case of Earth, plate tectonics– the movement of the great plates of land that compose Earth’s crust – played a major role. But what if the world is very tiny, like a comet? And what if it’s made of icy materials, not rocky materials like Earth? On February 19, 2019, the European Space Agency (ESA) described a new study pointing out a key process that shaped the evolution of comet 67P/Churyumov-Gerasimenko. This is the comet that was studied close-up, from orbit, by ESA’s Rosetta spacecraft for two years between August 2014 and September 2016. According to the new study, plate tectonics isn’t the driving process. Instead, ESA said, comet 67P/C-G likely evolved primarily due to geological stress arising from the comet’s dual-lobed shape.
Small, icy comets with two distinct lobes seem to be commonplace in the solar system, with one possible mode of formation a slow collision of two primordial objects in the early stages of formation some 4.5 billion years ago. A new study using data collected by Rosetta during its two years at Comet 67P/C-G has illuminated the mechanisms that contributed to shaping the comet over the following billions of years.
The researchers used stress modelling and three-dimensional analyses of images taken by Rosetta’s high resolution OSIRIS camera to probe the comet’s surface and interior.
Christophe Matonti of Aix-Marseille University, France, is lead author of the new study. He said:
We found networks of faults and fractures penetrating 500 meters (1,640 feet) underground, and stretching out for hundreds of meters.
Stress-formed fractures and terraces on Rosetta’s comet, via ESA.
According to the new study, these faults and fractures in the comet were created by shear stress, a mechanical force often seen at play in earthquakes or glaciers on Earth and other terrestrial planets. Shear stress happens when two bodies or blocks push and move along one another in different directions. Matonti commented:
This is hugely exciting: it reveals much about the comet’s shape, internal structure, and how it has changed and evolved over time.
These scientists said the model they developed found shear stress to peak at the center of the comet’s “neck,” the thinnest part of the comet connecting the two lobes. Co-author Olivier Groussin, also of Aix-Marseille University, France, said:
It’s as if the material in each hemisphere is pulling and moving apart, contorting the middle part – the neck – and thinning it via the resulting mechanical erosion.
We think this effect originally came about because of the comet’s rotation combined with its initial asymmetric shape. A torque formed where the neck and ‘head’ meet as these protruding elements twist around the comet’s center of gravity.
The scientists said their observations suggest shear stress acted globally over the comet and, crucially, around its neck. The fact that fractures could propagate so deeply into 67P/C-G also confirms that the material making up the interior of the comet is brittle, they said, something that was previously unclear.
But shear stress wasn’t the only factor at play on comet 67P/C-G. When comets come close to the sun, as this comet did in 2015, ices on their surface turn to vapor without ever going through a liquid phase. This process, known as sublimation, results in comet dust being dragged out into space. The scientists said this process of sublimation is a well-known process for deeply influencing a comet’s appearance over time. You can get a sense of some of the changes undergone by comet 67P/C-G in these images of dramatic outbursts captured by Rosetta.
Thus, these scientists said, their new study suggests that comet evolution is likely to result first from shear stress, acting over a timescale of billions of years following the formation of comets. Later in a comet’s life, especially if the comet falls into an orbit that takes it near the sun, sublimation erosion takes over.
Evolution of Rosetta’s comet over 4.5 billion years.
It’s good to bear in mind that comet 67P/C–G isn’t the only dual-lobed object known to astronomers. On January 1, 2019, NASA’s New Horizons spacecraft flew close to an object beyond Pluto – nicknamed Ultima Thule – located in the Kuiper belt, where icy comets and other small bodies reside, far from our sun. New Horizons found that Ultima Thule also has a dual-lobed shape. See the image below.
There are similarities between the shapes of comet 67P/C–G and Ultima Thule, but there are also differences. The same stress structures aren’t as apparent in Ultima Thule, the scientists said. Time – and probably more visits to comets and Kuiper Belt objects by more spacecraft – will reveal whether comet 67P/C–G’s evolution is unique or common among the small bodies of our solar system.
Ultima Thule versus comet 67P/C-G. They look really similar, don’t they? Both are icy objects that likely formed far from the sun. It might make you wonder how many other dual-lobed objects we’ll find in the far outer solar system.
Bottom line:Rosetta’s comet – aka comet 67P/Churyumov-Gerasimenko – looks like 2 icy balls apparently stuck together billions of years ago. A recent study, based on computer modeling, showed how the comet’s double-lobed structure guided its evolution.
