Despite their violent impacts, asteroids could still deposit water on Earth

Brown University researchers found new evidence that asteroids could have brought water to Earth — and they could also bring it to other planets.

In an effort to understand how the blue planet got all its blue (water), researchers at Brown University have turned to NASA and one of its biggest gun rooms.

Their what now?

Exactly how planets got all their water is still open to debate. Compounding the problem is the fact that traces of water were also found in comparatively dry places, such as the Moon’s mantle — dismissing ‘that’s just how the Earth rolls’ as a valid explanation. One possible explanation is that asteroids brought all this water here in the planet’s early days.

However, this theory never fared that well in the face of computer simulations.

“Impact models tell us that [asteroids] should completely devolatilize at many of the impact speeds common in the solar system, meaning all the water they contain just boils off in the heat of the impact,” says study co-author Peter Schultz, a professor in Brown’s Department of Earth, Environmental and Planetary Sciences, said in a statement.

“But nature has a tendency to be more interesting than our models, which is why we need to do experiments.”

In order to test the validity of this claim with as little computer simulations as possible, the team asked NASA for permission to use their Vertical Gun Range, housed at the Ames Research Center in California. The indoor ballistic facility was built during the 1960s when, NASA needed to see what happens during high-speed cosmic collisions, without having the luxury of powerful computers.

In lieu of real asteroids, the team used marble-sized cylinders of antigorite, a green mineral common in the oceanic crust that contains some 13% water by weight. A tray of dried, powdered pumice stone was used as a target, to simulate the loose layer of dusty minerals covering Earth’s bedrock, according to the authors. A plastic-lined well was affixed beneath this tray to capture the debris left by the simulated asteroid impact.

The team performed several trials, shooting the fake asteroids into the fake Earth at speeds in excess of 11,200 mph, which they write is “comparable to the median impact speed” in the asteroid belt. They report that on impact, some of the pumice stone melted, then quickly re-solidified, forming glass. Pieces of antigorite also got mixed in with the powder and formed breccia, a type of rock formed when bits of preexisting material get cemented together.

The surprising bit, however, was the water content in the debris. Lab analyses revealed that up to 30% of the mock asteroid’s water found its way into the debris left over in the tray — much more than models suggested was possible up to now. The findings lend weight to the theory that asteroids could have brought water to Earth from the depths of the universe.

“These new experiments raise the possibility that growing terrestrial planets trap water in their interiors as they grow,” the researchers wrote.

That being said, there is also evidence in support of Earth generating its own water, through geological processes. The truth is likely somewhere in the middle, but at this point, we can’t say for sure.

The paper “The delivery of water by impacts from planetary accretion to present” has been published in the journal Planetary Science.

Both NASA and ESA space missions have just released new videos plotting the orbits of tens of thousands of asteroids (and comets) orbiting our sun.

The study of asteroids has come a long way in recent decades, especially since astronomers realized that Earth is more or less at the center of a cosmic shooting gallery, in which asteroids are the bullets and we’re the target. Fortunately, this shooting is happening over a fantastically long timescale, with the biggest asteroids easiest to spot, so that – for example – astronomers now know there are no world- or even continent-destroying asteroids headed our way, anytime soon by human standards. Yet small asteroids sweep within our moon’s orbit all the time, sometimes weekly, certainly monthly. You can now subscribe to the Daily Minor Planet to see how often, in real time. The relatively new awareness of asteroids’ potential for harm is why astronomers have turned up their scrutiny of asteroid orbits and why – within the past week – both the European Space Agency (ESA) and NASA released new videos, based on spacecraft observations, showing asteroids orbiting our sun.

The NASA video and animation – above and below – plot the data gathered during the first four years of NASA’s NEOWISE or Near-Earth Object Wide-field Survey Explorer mission. NEOWISE has spotted and characterized more than 29,000 objects since December 2013. Most of those are asteroids in the main belt between Mars and Jupiter (gray dots in the visuals above and below), but the total includes nearly 800 near-Earth objects (NEOs, shown as green dots in the visuals) and more than 130 comets (yellow squares), mission team members said.

This movie shows the progression of NEOWISE’s investigation for the mission’s first 4 years following its restart in December 2013. Green dots represent near-Earth objects. Gray dots represent all other asteroids which are mainly in the main asteroid belt between Mars and Jupiter. Yellow squares represent comets.

And you might see that the study of asteroids is laborious, to say the least. NASA said that NEOWISE acquired more than 2.5 million infrared images of the sky during its fourth year of operation. Scientists combined these data with NEOWISE’s first through third years data into a single publicly available archive, containing approximately 10.3 million sets of images and a database of more than 76 billion source detections extracted from those images.

So you see there’s a lot of stuff out there, but – in a word of caution as you review the NASA video and animation above – it’s good to remember that space is vast. These visuals make it look as if the asteroids (the gray and green dots) are almost touching each other, and that’s an unintentional misrepresentation, caused by the fact that the scientists are trying to show you thousands of objects on your tiny computer screen.

In fact, if you were traveling through the asteroid belt in a spacecraft, you’d hardly be dodging asteroids, as sci fi movies like the one above love to depict. Instead, you’d be hard-pressed even to see an asteroid because, well, as you might or might not appreciate, there’s just lots of empty space out there.

That why – when asked if a spacecraft could travel through the asteroid belt safely – Sophie Allen of the UK’s National Space Academy answered that the chances of a collision would be about one in a billion.

Personally, I prefer the ESA video above to the NASA depiction because it doesn’t convey that false idea so completely, that the asteroids surrounding us are so densely packed they almost touch (they aren’t densely packed at all). The ESA video – released April 25, 2018 – is an animated view of some 14,099 asteroid orbits. The data came from ESA’s Gaia satellite’s second data release. The orbits of the 200 brightest asteroids are also shown, as determined using Gaia data.

HOW A PASSING STAR 70,000 YEARS AGO CHANGED THE SOLAR SYSTEM

• Another star buzzed the solar system 70,000 years ago and may have sent comets hurtling our way.
• It is possible our prehistoric ancestors saw the star in the sky.
  
• A new study also ID’ed eight objects that could have come from beyond our solar system.

About 70,000 years ago, around the time our ancestors were just beginning to leave Africa, a small red dwarf star passed remarkably close to the solar system. Scholz’s star came within a light-year of the sun, the closest such encounter we know of. Today, Scholz’s star sits about 20 light-years away, its stellar flyby a distant memory. But we are still seeing the influence of its visit.

Back in 2015, researchers led by Eric Mamajek, professor of astronomy and physics at the University of Rochester, studied the galactic orbits of Scholz’s star and our sun. They discovered that Scholz’s star and its brown dwarf binary companion probably wandered close to our solar system. At the time, the scientists concluded that Scholz’s star did not disturb the orbits of any objects in the solar system in any notable way when it passed by.

However, a new study in the Monthly Notices of the Royal Astronomical Society suggests this stellar flyby did in fact nudge comets from the Oort cloud, the ring of icy objects far beyond the planets that marks the edge of the solar system. These comets are now close enough to study in more detail, and while looking for them, the scientists also found eight objects that could be from outside the solar system entirely.

Comets From a 70,000-Year-Old Star Flyby

70,000 years ago, Scholz’s star and its binary companion passed within about 50,000 AU from the sun, the closest stellar encounter known.

The Oort cloud is a swarm of cometary bodies believed to be between 5,000 and 100,000 AU from the sun. Occasionally, these objects fall toward the sun, and some gain enough velocity to reach so-called hyperbolic orbits. These trajectories will eventually take them out of the solar system—unless they are influenced by another gravitational encounter with a giant planet, for example.

The new study, conducted by researchers at the Complutense University of Madrid and the University of Cambridge, analyzed the positions and velocities of 339 hyperbolic objects in the solar system. Normally, you’d expect the distribution of these objects across the sky to be more or less even. However, a group of them seem to be coming from the same radiant, or point of origin in the sky, and that area aligns with the encounter with Scholz’s star. Any objects that might have been pushed by Scholz’s star 70,000 years ago would only now be approaching the inner solar system.

“Out of those 339 [objects], 36 appear projected towards the relevant region in the constellation of Gemini (about 11 percent),” lead author Carlos de la Fuente Marcos of Complutense University of Madrid told Popular Mechanics in an email. “These are the ones that we suggest may have had an origin in the flyby with Scholz’s star.”

The researchers also found the suspect comets are traveling at a velocity around 1 km/s, or 2,200 mph, which could point to an “impulsive interaction” such as a stellar encounter. “Some of them were sent outwards and away from the solar system… some others were sent inwards and reached the inner solar system,” Marcos says. “Out of those sent inwards, a fraction passed close enough to the Earth to be detected by ongoing surveys. Most of the 36 objects pointed out above may fall into this category, the others may be chance alignments.”

The study identifies an exciting connection between these comets and the estimated location of the Scholz’s star flyby, but to truly confirm that the hyperbolic objects were pushed by that star in prehistoric times, additional modelling of both the comets and the star will be needed. By analyzing the 339 hyperbolic objects, however, the team turned up another tantalizing find—possible interstellar objects.

New Interstellar Suspects

Comet Hyakutake (C/1996 B2) might be an interstellar object captured by the solar system.

In addition to the comets that could have been hurled in by Scholz’s star, the study found eight objects that may be new interstellar candidates. The only confirmed object from outside the solar system to visit our neighborhood of planets is ‘Oumuamua, an elongated asteroid that made a close pass to Earth in October 2017. These additional eight objects are icy hyperbolic bodies with a velocity of 1.5 km/s or more, suggesting they could be interstellar comets.

“Statistically speaking, their paths are probably interstellar as their inbound velocities were significantly higher than those of the bulk of the other hyperbolic comets [2 to 30 times higher],” says Marcos. “As far as we can tell, the eight candidates to being interstellar interlopers have been singled out in our work for the first time.”

It’s unlikely that all eight of these objects have interstellar origins, as some may have formed in the solar system and accelerated during encounters with large objects. “I do think that the 1.5 km/s they used as a cut-off is probably a bit low, so I suspect that some of the eight candidates they identify are not true interstellar objects,” says Alan Jackson, a postdoc researcher at the Centre for Planetary Sciences at the University of Toronto who recently published a study that suggests ‘Oumuamua likely came from a binary star system. “The two that they identify as their best candidates, C/2008 J4 (McNaught) and C/2012 S1 (ISON), are I think fairly robust.”

If any of these objects are confirmed as interstellar interlopers, it would provide an icy comet from beyond the solar system to study alongside the rocky asteroid ‘Oumuamua, which turned out to be an object unlike anything astronomers had ever seen. Most astronomers believe interstellar objects fly through the solar system regularly, and our telescope survey projects are advancing toward the point of finding them much more frequently.

Red Star in the Ancient Sky

When the red dwarf star and its brown dwarf companion flew by the outer reaches of the solar system, it is possible that humanity’s ancestors saw the star in the sky.

Scholz’s star was almost certainly not visible generally, but red dwarfs can periodically flare up due to magnetic activity and grow many times brighter than their standard magnitude. The dimmest stars humans can see with the naked eye have an apparent magnitude (intrinsic magnitude modified by distance) of about 6 (lower numbers are brighter). If Scholz’s star was on the farther end of estimates, it would have had an apparent magnitude of about 11, and closer in an apparent magnitude of perhaps 7.9.

Even at the greater distances, “those flares could be visible to human eyes without optical aids,” says Marcos. (However, Marcos stresses that whether or not the star was visible to human ancestors is not discussed in the paper.)

It is tempting to imagine that prehistoric humans looked up one night to catch a glimpse of Scholz’s star flaring up in the sky. Perhaps they considered it a sign of a bountiful hunt, or an omen of doom. Seventy thousand years later, equipped with all the advantages of modern science, we may have found new evidence of Scholz’s visit to the solar system, the most distant comets of the Oort cloud in for a closer look.

INTERSTELLAR VISITOR ’OUMUAMUA PROBABLY CAME FROM A TWO-STAR SYSTEM

Astronomers are now certain that the mysterious object detected hurtling past our sun last month is indeed from another solar system. They have named it 1I/2017 U1(’Oumuamua) and believe it could be one of 10,000 others lurking undetected in our cosmic neighbourhood.

The certainty of its interstellar origin comes from an analysis that shows its orbit is almost impossible to achieve from within our solar system.

Its name comes from a Hawaiian term for messenger or scout. Indeed, it is the first space rock to have been identified as forming around another star. Since asteroids coalesce during the process of planet formation, this object can tell us something about the formation of planets around its unknown parent star.

The latest analyses with ground-based telescopes show that ’Oumuamua is quite similar to some comets and asteroids in our own solar system. This is important because it suggests that planetary compositions like ours could be typical across the galaxy.

It is thought to be an extremely dark object, absorbing 96% of the light that falls on its surface, and it is red. This colour is the hallmark of organic (carbon-based) molecules. Organic molecules are the building blocks of the biological molecules that allow life to function.

It is widely thought that the delivery of organic molecules to the early Earth by the collision of comets and asteroids made life here possible. ’Oumuamua shows that the same could be possible in other solar systems.

Its characteristics have been published by two independent groups of astronomers. The first group, led by Karen Meech, University of Hawaii, also found that ’Oumuamua was extremely elongated and roughly 400 metres long. Using the European Southern Observatory’s Very Large Telescope(VLT) they also found that it rotated once every 7.3 hours.

The other group of astronomers, led by David Jewitt, University of California Los Angeles, estimated how many other interstellar visitors like it there might be in our solar system.

Surprisingly, they calculate that another 10,000 could be closer to the sun than the eighth planet, Neptune, which lies 30 times further from the sun than the Earth. Yet these are currently undetected.

Each of these interstellar interlopers would be just passing through. They are travelling too fast to be captured by the gravity of the sun. Yet it still takes them about a decade to cross our solar system and disappear back into interstellar space.

If this estimate is correct, then roughly 1,000 enter and another 1,000 leave every year – which means that roughly three arrive and three leave every day.

Using robotic telescopes such as Pan-STARRS, the one that detected ’Oumuamua, to look for asteroids is a priority for astronomers as they concentrate on discovering potentially hazardous objects that could impact Earth.

Imminent upgrades to these survey telescopes and improvements in data processing techniques mean that astronomers will soon be able to detect smaller and fainter objects. They expect a number of these to be interstellar interlopers like ’Oumuamua.

What If Earth Started Spinning Backward?

During Earth's yearlong orbit around the sun, our planet completes a full rotation on its axis — which runs from the North Pole to South Pole — every 24 hours, spinning at a rate of about 1,040 mph (1,670 km/h) as measured at the equator. Its rotation direction is prograde, or west to east, which appears counterclockwise when viewed from above the North Pole, and it is common to all the planets in our solar system except Venus and Uranus, according to NASA.

As Earth rotates, the push and pull of its momentum shapes ocean currents, which, along with atmospheric wind flows, produces a range of climate patterns around the globe. These patterns carry abundant rainfall to humid jungles or divert moisture away from rain-parched badlands, for example.

Going retro

To study how Earth's climate system is affected by its rotation, scientists recently modeled a digital version of Earth spinning in the opposite direction — clockwise when viewed from above the North Pole, a direction known as retrograde, Florian Ziemen, co-creator of the simulation and a researcher with the Max Planck Institute for Meteorology in Germany, told Live Science in an email.

"[Reversing Earth's rotation] preserves all major characteristics of the topography like sizes, shapes and positions of continents and oceans, while creating a completely different set of conditions for the interactions between the circulation and the topography," Ziemen said.

This new rotation set the stage for ocean currents and winds to interact with the continents in different ways, generating entirely new climate conditions around the world, the researchers reported in a project overview.

Spin cycle

To simulate what would happen if Earth were to spin backward (retrograde instead of prograde), they used the Max Planck Institute Earth System Model to change Earth's relationship to the sun and reverse the Coriolis effect, an invisible force that pushes against objects traveling over a rotating planet's surface.

Once those alterations were in place and the model showed Earth spinning in the opposite direction, the researchers observed the changes that emerged in the climate system over several thousand years, as feedback among the rotation, atmosphere and ocean went to work on the planet, the scientists wrote in a description of the work, which they are currently preparing for publication.

Overall, the researchers found that a backward-spinning Earth was a greener Earth. Global desert coverage shrank from about 16 million square miles (42 million square kilometers) to around 12 million square miles (31 million square km). Grasses sprouted over half of the former desert areas, and woody plants emerged to cover the other half. And this world's vegetation stored more carbon than our forward-spinning Earth, the researchers discovered.

However, deserts emerged where they never had before — in the southeastern U.S., southern Brazil and Argentina, and northern China.

Turn, turn, turn

The change in rotation also reversed global wind patterns, bringing temperature changes to the subtropics and midlatitudes; continents' western zones cooled as eastern boundaries warmed, and winters became significantly colder in northwestern Europe. Ocean currents also changed direction, warming seas' eastern boundaries and cooling their western ones.

In the simulation, AMOC— the ocean current responsible for transporting heat around the globe — disappeared from the Atlantic Ocean, but a similar and slightly stronger current arose in the Pacific, carrying heat into eastern Russia. This was somewhat unusual, as a prior study that modeled a reverse-spinning Earth did not see this change, Ziemen told Live Science in an email.

"But as the AMOC is the result of many complex interactions in the climate system, there can be a lot of reasons for this difference," he said. [Earth Pictures: Iconic Images of Earth from Space]

Altered sea currents in the Indian Ocean also allowed cyanobacteria to dominate the region, which they have never managed to accomplish while the Earth spins in its current direction, the researchers discovered.

But for Ziemen, the greening of the Sahara was the most intriguing change that appeared in their "backward" model of Earth.

"Seeing the green Sahara in our model got me thinking about the reasons why we have a desert in the Sahara, and why there is none in the retrograde world," Ziemen said. "It is this thinking about the most basic questions that fascinates me about the project."

Renowned Scientist And Friend Of Stephen Hawking Claims to Have Detected Extraterrestrial Organisms

Scientists announce the discovery of three types of alien bacteria.

The Indian Space Research Organisation has announced that a recent study has uncovered three types of bacteria which are believed to be from an extra-terrestrial origin.

According to the renowned astrophysicist Jayant V. Narlikar who led the study, the bacterial organisms were detected by his team at the IRSO with the use of high altitude balloons. These balloons were propelled into the upper reaches of the atmosphere and collected material from the stratosphere. The balloons then returned to Earth where they were analysed by the team. In addition to a number of bacterial organisms which are commonly found on this planet, the team also uncovered three different types of bacteria which do not match any known organism on Earth.

“Detection of extraterrestrial bacteria highlights the possibility of life beyond earth and it is good news for humanity,”

said Professor R. K. Chaudhury of the Indian Institute of Astrophysics speaking of the findings. Professor Narlikar was similarly buoyant when announcing the findings of his study which suggests that the building blocks for life are present elsewhere in the universe.

“With modern technological advancement, we will be able to provide conclusive evidence for the presence of life outside the confines of the earth in the near future", he said.

The fascinating research has been praised not only for its wide implications but also because of it is hoped that it will boost the profile of the Indian space agencies which have typically been marginalized in comparison to bodies such as NASA and the ESO. “With these findings, Indian study in the field of extraterrestrial investigations can be said to have reached a competitive stage in the global arena. There is a dedicated group in India that is working towards the targets of extraterrestrial studies, we are hopeful of more results in the future, "said Professor Chaudhury.

Narlikar was a close friend of Stephen Hawking

"During our university days, I was told that Hawking had only two years to live and soon his physical deterioration started but he showed tremendous determination and willpower and did marvelous work in astrophysics," Narlikar said.

Bam! Cannon Experiment Shows How Asteroids Delivered Water to Earth

In the study, researchers blasted marble-size projectiles designed to mimic ancient, water-rich asteroids at dry targets, hitting staggering speeds of around 11,000 miles per hour. Samples of impact glasses created during an impact experiment are shown

These projectiles had a similar composition to carbonaceous chondrites, a group of meteorites that come from ancient, water-rich asteroids. In the early stages of Earth's evolution, these asteroids frequently hit the planet at very high speeds. The experiment, described in a paper published online today (April 25) in the journal Science Advances, revealed that during such collisions, up to 30 percent of the water from the asteroid could get trapped in the debris created by the impact. [Photos: Asteroids in Deep Space]

"The origin and transportation of water and volatiles is one of the big questions in planetary science," said Terik Daly, who's now a postdoctoral researcher at Johns Hopkins University but led the study while completing his doctorate at Brown University. 

"These experiments reveal a mechanism by which asteroids could deliver water to moons, planets and other asteroids," Daly said in a statement.

f

Astronomers originally thought that Earth's water came mostly from comets. However, recent research has pegged asteroids as the probable main delivery system. Measurements have shown that water found on Earth has a similar composition of isotopes — variants of the same chemical element that differ in the number of neutrons — as water contained in carbonaceous asteroids. 

But it wasn't clear how those asteroids could have delivered their water to what was once a completely arid Earth. 

"Impact models tell us that impactors should completely devolatilize at many of the impact speeds common in the solar system, meaning all the water they contain just boils off in the heat of the impact," study co-author Peter Schultz, a professor in Brown's Department of Earth, Environmental and Planetary Sciences, said in the same statement. "But nature has a tendency to be more interesting than our models, which is why we need to do experiments."

When the researchers shot their mini-meteorites at the mini-Earths, they observed that a significant proportion of the water from the projectiles got trapped in rock — both in the stuff that was melted by the heat of the impact and in the material that coalesced from the jumble of impact debris, a type of rock known as a breccia.  

"What we're suggesting is that the water vapor gets ingested into the melts and breccias as they form," Schultz said. "So even though the impactor loses its water, some of it is recaptured as the melt rapidly quenches."

The researchers said the process could also explain the presence of water in the lunar mantle and some other areas of the moon, such as Tycho Crater. 

"The point is that this gives us a mechanism for how water can stick around after these asteroid impacts," Schultz said. "And it shows why experiments are so important, because this is something that models have missed."

The findings could explain how asteroids deliver water throughout the solar system, helping to account for traces of water spotted on the moon and other planetary bodies

DE WAARHEID BRENGEN OVER UFO'S WORDT STEEDS GEVAARLIJKER

Achter de schermen zijn geheime krachten aan het werk om díegenen die voor de machthebbers onwelgevallige zaken naar buiten brengen, keihard aan te pakken. 

Welke belangen er voor hen op het spel staan, wordt duidelijk wanneer je ziet hoever ze bereid zijn te gaan om de waarheid verborgen te houden. 

Natuurlijk zijn er heel veel zaken die de werkelijke machthebbers graag verborgen houden en het is zo langzamerhand een bekend feit dat ook overheden zich actief bemoeien met wat er op het internet gebeurd en daar zelfs op een heel geniepige manier actief zijn.

Er zijn overheidsdienaren in zo goed als alle landen die niets anders doen dan opzettelijk zaken vertroebelen, twijfel en tweedracht zaaien en er meer in het algemeen voor zorgen dat degene die de onwelgevallige waarheid brengt belachelijk wordt gemaakt of als volkomen overkomt. 

Via uitgelekte NSA documenten is nu ook precies bekend wat de opdrachten zijn die deze zogenaamde internettrollen mee krijgen.

Het door overheden inzetten van trollen gebeurt overal en die van ons plaatste zelf enkele jaren geleden een advertentie voor het werven van dergelijke trollen, iets waar door de Partij van de Dieren destijds nog kamervragen over zijn gesteld, waarop zoals gebruikelijk ontwijkende en nietszeggende antwoorden kwamen. 

Wij hebben enkele jaren geleden een complete handleiding voor trollen gepubliceerd en daarin zie je precies hoe ze te werk gaan en hoe je ze in de praktijk ook beter kunt herkennen. 

Het trollen op internet is één ding, maar het gaat nog veel verder en dan wordt het regelrecht eng voor degene die de waarheid naar buiten durft te brengen. 

Iemand die dat doet met veel succes op het gebied van vreemde zaken en veelal ook UFO gerelateerde onderwerpen is een jongeman die bekendstaat onder de naam Tyler en een heel succesvol Youtube kanaal exploiteert onder de naam Secure Team. Wij gebruiken regelmatig zijn bevindingen in artikelen.

Tot niet zo gek lang geleden had hij een mijlpaal bereikt en werd de grens van een miljoen abonnees overschreden en wanneer je nu kijkt, zit hij al boven de anderhalf miljoen. 

Tyler krijgt via zijn abonnees veel informatie en beelden binnen en heeft ongetwijfeld via zijn kanaal veel UFO gerelateerde zaken gepubliceerd waarvan de machthebbers niet willen dat gewone burgers die zien. 

Vorig jaar september gebeurden er een aantal vreemde zaken bij Tyler thuis en na een “ongeluk” met zijn motor eindigde hij in het ziekenhuis, waar we toen het volgende over schreven.

Uiteraard loop je dan ook aardig in de kijker bij overheden en dan vooral een bepaald deel daarvan, sinistere mannen in donkere pakken die dan ook Men in Black (MIB), worden genoemd. 

Wij willen iedereen aanraden om even de tijd te nemen om te kijken naar de volgende video die Tyler ongeveer een maand geleden maakte toen er dagenlang een vreemde auto naast zijn huis stond die hem met gierende banden achtervolgde toen hij op zijn motor wegreed. 

De volgende video is van nu, een maand later en opgenomen afgelopen donderdag in het ziekenhuis waar Tyler ligt met talloze gebroken botten na een motorongeluk. 

Hij zegt verder niets over hoe het ongeluk heeft kunnen gebeuren, maar gezien de gebeurtenissen rondom zijn huis de afgelopen maand, is het aannemelijk dat die Men in Black verantwoordelijk zijn voor het feit dat een jonge onderzoeker nu met gebroken botten in het ziekenhuis ligt. Hij belooft in de video dat zodra hij beter is terug aan het werk te zullen gaan.

Inmiddels is hij weer min of meer hersteld en weer iedere dag bezig met zijn kanaal en het publiceren van UFO gerelateerde zaken. Wat hij nu echter merkt, is dat er steeds meer trollen actief worden in de commentaar sectie van zijn Youtube kanaal.

Op zich is dat ook te verwachten, maar dan wordt er door iemand het volgende commentaar geplaatst.

Een duidelijk trollen account dat kort daarvoor is aangemaakt, maar waar de koude rillingen je pas écht van over de rug lopen is het feit dat in het commentaar ene Dr. Asher wordt genoemd. 

Dr. Asher was niet de behandelend arts in het ziekenhuis waar Tyler na zijn motorongeluk terechtkwam, maar de chirurg die de operatie uitvoerde en die met schroeven een stalen pin aan zijn been heeft gemonteerd. 

Deze informatie heeft Tyler nóóit met iemand gedeeld, heeft nooit ergens ook op internet gestaan en hij was zelf alweer bijna de naam van die chirurg vergeten. 

Ook trollen maken fouten, maar wat hier wel uit blijkt is dat ze in de achtergrond Tyler bespioneren, al zijn bewegingen in de gaten houden en beschikken over al zijn privé informatie. 

Het kanaal van Tyler groeit als kool, hij krijgt steeds meer de beschikking over spectaculair en verborgen beeldmateriaal via zijn abonnees.

De enige vraag die nog open staat is: Hoe lang nog voordat Tyler weer “een ongeluk” krijgt. En waar normaal toch wel ongeveer iedere dag nieuwe video's van Tyler verschenen, is de navolgende van enkele dagen geleden op het moment van schrijven, de laatste.

BIJZONDERE WAARNEMINGEN BOVEN ENGELAND

Het is enige tijd vrij rustig geweest op het gebied van onbekende vliegende voorwerpen in de lucht, maar nu lijken ze weer helemaal terug. 

Van een man die wandelt en een klassieke retro UFO weet vast te leggen, tot een stel dat tot hun stomme verbazing een moederschip filmt boven de zee met een kleinere verkenner. 

De foto’s die hierna volgen zijn genomen door een man in het Engelse Newton Abbott in Devon. Deze streek van Engeland staat sowieso al bekend als een UFO hotspot, dus ter plaatse kun je dingen verwachten.

De man die de foto’s gemaakt heeft zegt dat hij naar de lucht keek en iets snel op hem af zag komen. Hij gebruikte een Nikon P900 camera en zag al snel iets dat veel lijkt op het klassieke model UFO, oftewel de retro UFO met de herkenbare vliegende schotelvorm. 

De UFO had volgens de man een enorme snelheid, was behoorlijk hoog in lucht en vloog via het stadscentrum weer uit het zicht. Deze waarneming is aangemeld bij Mufon onder zaak nummer 91544 en de man in kwestie zegt vol ongeduld uit te kijken naar een volgende waarneming en ook dat hij in dat bepaalde gebied regelmatig UFO’s ziet.

De tweede waarneming is afkomstig van Isle of Man en is heel bijzonder.

Het is in de avond van 17 april als een stel langs een volkomen verlaten en afgelegen deel van het strand van het Isle of Man loopt te wandelen. Dan, opeens zien ze iets.

Eerst een soort bol die lijkt af te dalen naar een boot die in het water ligt, wat echter bij nader inzien dat niet blijkt te zijn omdat het boven het wateroppervlak zweeft.

Waar het alle schijn van heeft, is dat we hier te maken hebben met een soort verkenner orb die terugkeert naar het moederschip.

Hieronder volgen de bewegende beelden en zoals je aan de stomverbaasde en opgewonden stem van de man kunt horen, is hij volkomen overdonderd en is hoorbaar dat hij op een gegeven stamelt dat "ze" iets aan het testen zijn.

Opgewonden Engelsen willen nog wel eens het f*#@ woord gebruiken, dus wees voorbereid, deze Brit vormt daarop geen uitzondering.

Het grootste ding in het universum? Astronomen zien fantastische gebeurtenis van 12 miljard jaar geleden - HLN.be

Bron: The Guardian

Het licht van de samensmelting begon naar ons te reizen zo’n 1,4 miljard jaar na de Big Bang, toen het universum slechts een tiende van zijn huidige leeftijd had. Aangezien de samensmelting zo lang geleden plaatsvond, zou het gigantische sterrenstelsel dat zo ontstond alsmaar groter zijn geworden. Berekeningen suggereren dat nog honderden andere sterrenstelsels zouden verzwolgen zijn door de cluster, met een massa gelijk aan 1.000 biljoen zonnen. Het zou zo het grootste gekende object in het universum zijn.

14 tot 30 sterrenstelsels

De vondst onthult maar liefst 14 sterrenstelsels die samengepropt zitten in een gebied dat slechts vier keer zo groot is als de diameter van galactische schijf van onze Melkweg. Een nabijgelegen hoop licht die nog niet ontleed werd in individuele objecten, suggereert dat het totale aantal sterrenstelsels dat afstevent op de botsing eerder een dertigtal is.

Tijdens de eerste paar miljoen jaren van de kosmische geschiedenis begon normale materie en donkere materie samen te klitten, waardoor uiteindelijk clusters van sterrenstelsels ontstonden. Vandaag kunnen dergelijke clusters tot duizend sterrenstelsels bevatten, grote lappen donkere materie, immense zwarte gaten en gaswolken die temperaturen van meer dan een miljoen graden kunnen bereiken.

Belang

De vondst op zich is al spectaculair, maar het feit dat hij dateert van zo vroeg in de geschiedenis, biedt een enorme uitdaging voor onze kennis van de manier waarop structuren in het universum ontstaan, reageert astrofysicus en medeauteur van de studie Scott Chapman van de Dalhousie University in het Canadese Halifax. De enorme cluster SPT2349-56 ontstond bovendien twee keer zo snel als de huidige theorieën aanwijzen.

Het onderzoek werd gepubliceerd in vakblad Nature.

China lanceert vijf aardobservatiesatellieten tegelijk - HLN.be 

Bron: belga

Vanop de noordwestelijke lanceerbasis Jiuquan vertrok een Lange Mars-11 draagraket. Die zette vijf Zhuhai-aardobservatiesatellieten in de ruimte af.

Volgens Xinhua is de Zhuhai-1 een commercieel aardobservatiesatellietsysteem. Het moet data leveren voor landbouw, grondstoffen, milieubescherming en transport.

Op 15 juni 2017 stuurde Peking al twee kunstmanen van dit systeem de ruimte in. Het was de 272ste missie van een telg van de Lange Mars-draagraketfamilie.

Recent archaeological discoveries suggest that Siberia was once the home of a possibly highly developed Ice Age civilization. Relics ranging from massive unexplained megalithsto mysterious walled structures have been found, suggesting that these people were capable of significant architectural feats. While it has been known that there were tribes of people living in this area during the Ice and Stone ages, these new discoveries suggest that these civilizations were more advanced than previously thought. Now, a new analysis of a creepy humanoid statue found in the Ural mountains has been dated to even before the pyramids. Is there a lost chapter of human history waiting to be unearthed in Eurasia and Siberia?

Possibly, if a recent analysis published in Antiquity is confirmed. The study examines the Shigir Idol, believed to be the most ancient wooden sculpture in the world. The statue was discovered in fragments beginning in the 19th century in an open-air gold mine which contained other ancient artifacts. Several studies have dated the statue to be around 9,000 years old, but this latest study claims that age is more likely 11,600 years old – twice as old as the pyramids.

The purpose and meaning of the idol remain shrouded in mystery, but it does bear resemblance to other Ice Age art found near Turkey’s Göbekli Tepe, believed to be the oldest known temple in the world. The authors of this recent study write that the statue “may reflect encoded mythologies” and could provide a glimpse into the folklore and beliefs of early civilizations indigenous to this part of the world:

The vertical placement of the faces could indicate the presence of an internal hierarchy among the images, or a sequence of events. Above all, however, the Shigir sculpture is unique within the early art of Eurasia and offers the potential for a better understanding of the spiritual world of early hunter-gatherer-fishers of the forest zone of Eurasia.

Pre-industrial human civilizations had only natural materials at their disposal, meaning the ravages of time have likely rendered into dust all evidence of these early civilization. Will we ever truly understand our own species’ early history?

Doctors think they’re so smart. Sure, they might be able to save our lives and everything, but the history of medicine shows us that what is cutting-edge thinking today will someday (maybe soon) be looked down upon as foolish gobbledygook. I mean, we used to give children morphine to calm them down, people used to rub mercury on themselves for all sorts of conditions, and lobotomies were considered a legitimate form of medicine through the mid-20th century. That’s no reason not to go to the doctor or get vaccinated in the meantime, though. It merely shows that medical science, like all sciences, are constantly reinventing themselves in light of new discoveries and likely always will. It’s just the nature of scientific knowledge.

Case in point: scientists have just discovered an entirely new, unknown form of DNA hiding right inside human cells. While most human DNA assumes the double helix corkscrew form, scientists have speculated for years that there might be another form hidden within the human genome: a four-stranded ‘knot’ known as i-motif. A new study in Nature Chemistry claims to have finally found evidence that i-motif DNA exists in the human genome, and that it might play an unknown-but-highly-important regulatory role in human genetics.

These i-motif forms are thought to fold and unfold in and out of existence during transcription, the process through which DNA sequences are ‘copied’ into RNA and subsequently expressed as various biological functions. Marcel Dinger, head of the Kinghorn Centre for Clinical Genomics at the Garvan Institute of Medical Research in Sydney, says the discovery is “pretty spectacular” and only further highlights the fact that the human genome is still pretty much a mystery to science:

There’s so much of the genome that we don’t understand, probably like 99 percent of it. Seeing DNA folded like this in living cells makes it possible to decode those parts of the genome and understand what they do.

DNA was formally discovered less than a hundred years ago, and the disciplines of genetics and genomics are still in their infancy, relatively speaking. Who knows what groundbreaking genetics discoveries are just around the corner now that the human body has become the plaything of so-called biohackerslooking to augment their own genomes in the privacy of their own basements?

Yoink.

With every genetics discovery comes the possibility that Homo sapiens might soon grab the reins of our own genetic destiny and forge a new evolutionary path of our own choosing – or more likely, some type of hybrid biological/technological one. It’s gonna be a weird future.

UFO caught on video falling to the ground during Somerset storm, UK

A mysterious falling object has been filmed during a storm in Bridgewater Somerset County, UK on April 21, 2018.

The storms hit Somerset on Saturday afternoon and Megan Taylor caught some dramatic footage of lightning in the skies above the town, reports somersetcountygazette.

But besides the lightning she also captured an unidentified black object falling from the sky just after a lightning strike.

Speaking to MailOnline, Nigel Watson, author the Haynes UFO Investigation Manual, said: 'The video does make it look like this is something solid falling from the sky, like one of the Martian cylinders in The War of the Worlds.
