Canada – Les OVNI sont majoritairement observés au Québec
Canada – Les OVNI sont majoritairement observés au Québec
L’organisme manitobain UFO Research a compilé des données sur les observations d’OVNI survenues au Canada au cours de l’année 2017. Il s’avère que le Québec est la province où ce genre de phénomène est le plus souvent rapporté.
En 2017, 1101 observations d’OVNI ont été rapportées au Canada. Le Québec en regroupe, à lui seul, 518, ce qui constitue un véritable record ! Ce nombre est en nette augmentation depuis 2016 où « seulement » 430 objets volants non identifiés avaient été signalés.
La province de l’Ontario, qui est la plus peuplée du pays, ne compte que 241 observations d’OVNI, tandis que 128 ont été rapportées en Colombie-Britannique.
Parmi les grandes métropoles du pays, c’est à Montréal que la population a observé le plus d’OVNI avec 74 signalements. En seconde position, on retrouve Toronto avec 57 observations.
Les récits d’OVNI sont très différents et les témoins ont vécu des expériences parfois étonnantes. Ainsi, un objet gris en forme de beignet a été vu en train de tourner sur lui-même à Rimouski. À Saint-Jean-Baptiste, un engin de couleur rouge s’est approché de 10 campeurs avec de s’éloigner dans la stupeur générale.
Selon cet organisme, 8 % des cas recensés demeurent complètement inexpliqué, alors que 43 % ne sont que de simples « lumières dans le ciel ».
Les durées de ces observations sont d’environ 15 minutes après quoi les OVNI disparaissent à la vue des témoins.
Depuis 1989, année à partir de laquelle Ufology Research a commencé à collecter ses données, le nombre de signalements n’a cessé de croître. Au tournant des années 2000, la tendance s’est accrue de manière surprenante. 2012 fut une année exceptionnelle puisque près de 2000 OVNI ont été observés.
A senior SETI (Search for ExtraTerrestrial Intelligence) astronomer recently posted an essay on UFOs inside the Huffington Post where he first said: "Allow me to first be aware that that is a phenomenon worth of interest. If aliens are honestly striking out in our 'hood, it is difficult to assume every other truth extra worth of observe." Then he concludes with: "The truth is, in case you're positive that our planet is website hosting alien visitors, the way to advantage popularity for your point of view is to prove it, now not insist that the hassle lies with 1/3 parties. The blame sport is a cop-out."
WTF is that this man announcing? UFOs are critical however it is up to others to do all of the hard yards and show that UFOs and aliens are associated. You can pretty much hear the author scream out WE REQUIRE PROOF so long as the weight is on others to provide you with the smoking gun!
WE REQUIRE PROOF! That's all first-class, well and suitable in principle, an in a perfect global, besides the common member of the awesome unwashed does not have the call-logo, instructional bona-fides or assets required. No depend what 'proof" the exquisite unwashed provide up, the WE REQUIRE PROOF demands of the numerous (scientists) outweigh the skills of the few (the super unwashed) to proved the required goods. If I ring up a pinnacle scientist at a pinnacle college and say I actually have a bit of an alien spaceship, do you without a doubt suppose they'll pay attention to me or slam down the cellphone uttering "every other bloody wacko losing my time"! So the 'blame sport' is perhaps greater a plea for people with the medical bona-fides, and the resources and the credibility and revered home institutions to take the fantastic unwashed a tad more significantly with regards to UFO reviews and get their hands grimy analyzing the problem.
I play the blame game. I placed blame on individuals who may want to, but may not get their hands dirty. It's highbrow cowardice pure and simple. The fairly apparent if unstated message is I'm interested by ET, I'm a SETI scientist via career, however I'm now not interested in UFOs except someone else provides the proof that there may be an actual alien connection. I'm now not interested in UFOs due to the fact I might not get outside investment to look at them. That's because I've were given an excessive amount of on my plate already. That's due to the fact I'd instead sit on my ass and allow the top notch unwashed do the dirty work. That's due to the fact a person may make amusing of me, like my expert colleagues. The sociology (workplace politics) of the technological know-how community normally runs some thing alongside the strains of don't stray beyond the mainstream; do not think out of the box; don't rock the boat or you may become like Jonah and tossed overboard with out a whale in sight.
So holier than thou essays like that published by using 'Mr. SETI' aren't absolutely beneficial; relevant scientists need to place up a few reputable technology or shut up considering the fact that if they are truely not a part of the answer, they're part of the problem status within the way of an answer!
Let's forget about the super unwashed for the instant; allow's talk nerdy speak and cope with proof, no longer proof, just evidence, that some thing atypical is afoot thru observations from astronomers, expert colleagues of SETI scientists, and their reported anomalous observations which can be in the scientific literature. Now albeit it's 'colleagues' from several generations ago and way before cutting-edge SETI instances, but that doesn't regulate their educational bona-fides nor what they said inside the professional literature.
I talk to the numerous ancient sightings of Neith (suggested satellite tv for pc of Venus) and the intra-Mercurial planet Vulcan in conjunction with severa different sightings of alleged planets inside the orbit of Mercury. Not one, or but multi-dozens of reports are in the scientific literature for each. That's similarly to those multi-dozens of sightings of unexpected by uncharted and unknown items that made unexpected transits of the Sun and Moon. So, expert astronomers are on file as having seen, for all sensible functions, unidentified 'aerial' phenomena. Now we recognise there may be no Neith and there's no Vulcan, and many others. So exactly what did scientists in the astronomical career take a look at? A UFO with the aid of some other name remains a UFO. Okay, it is simply proof, not proof. Still, UFO observations are not completely the property of the exquisite unwashed.
WE REQUIRE PROOF! Okay, even though scientists do not need to actively take part, their demand WE REQUIRE PROOF (lay it at the slab in my lab) sounds affordable, till you realise that the ones identical scientists receive the reality of many other things that they similarly can not study on a slab inside the lab, matters that simplest may be visible or photographed.
An obvious working example is the ones stars inside the night time sky. You see them; you can picture them, however so far you can't observe the bodily object within the laboratory! You cannot placed a celebrity on the slab. So, if stars are ideal, why now not UFOs? Well, stars may be consequently they're; UFOs cannot be therefore they are not*.
Scientists have a readymade excuse for now not being able to verify the bona-fides of stars as laboratory specimens; they're out of attain - way too remote to grab keep of. But they nevertheless argue that stars aren't illusions or misidentifications or all-in-the-thoughts or hoaxes due to the fact astrophysical concept supports stars being what scientists consider they may be. Of direction in a manner of speakme starlight may be 'captured' and analysed in the lab, and at least stars have the decency of making their appearance on agenda. Still, you can't have a look at up close and private the physical megastar itself.
So as a generality, in defence to an anti-UFO stance, scientists will say there are theoretical reasons for accepting the reality of factors they can not positioned their mitts on, implying that there are no theoretical motives supporting the UFO ETH (ExtraTerrestrial Hypothesis). Alas and alack, as an extra counterattack, as stars (and rainbows - see beneath) are supported with the aid of astrophysics' idea, there is also an actual theoretical situation that almost demands that there be UFOs and that UFOs be extraterrestrial spacecraft - it is called the Fermi Paradox. That simply essentially says that even supposing there may be handiest one superior technological civilization 'available' with the ability to "boldly go", then the time it would take to discover (even at low sub mild velocities - say 1% to 10% the speed of light) and colonize end-to-cease our galaxy is however a tiny, tiny fraction of the age of our galaxy. So where is each person? They need to, in the event that they exist in any respect, through rights be right here. Why would they pay unique interest to the 0.33 rock from the Sun? While stars and planets are dimes-a-dozen, abodes with biospheres are likely as uncommon as chook's tooth - that is why. Planet Earth is a hen's tooth! Alas, even as astrophysical theory passes their muster, the Fermi Paradox does not reduce their mustard apparently.
Okay, for terrestrial scientists, physical famous person-stuff cannot be placed at the lab's slab. But there are parallels a lot in the direction of home wherein that excuse of extreme distance falls far brief. Now here is a parallel. The rainbow is the case in point. If scientists can play UFO skeptic, I can play the position of rainbow skeptic.
If you are saying you've got seen a rainbow, you cannot prove that to me since you can't convey the rainbow, or any part of it (like say the related pot-of-gold), into my lab and region it on the slab for me to hammer away at or placed underneath the microscope. You obviously trust inside the truth of rainbows, but you can't put the only you see inside the sky to your lab's slab either. Okay, you understand and I recognise that rainbows exist, but the important factor is that you can't show to me (or anybody) that you saw a rainbow. We all understand eyewitness testimony, ain't really worth the fee of spit in a bucket. As for snap shots, being the grand skeptic I am, absolute confidence your photos of rainbows are fakes, pure and easy. I REQUIRE PROOF of rainbows and you cannot provide it.
Can you capture and put an real rainbow within the sky right into a laboratory surroundings and situation it to merciless and unusual punishments? You can artificially create one in the lab, but it is not quite the identical thing - it is not the real McCoy. And what approximately that associated physical trace - the pot-of-gold at the quit of the rainbow? I've but to examine of any laboratory evaluation of that pot and that gold. How can we are aware of it's honestly gold with out slab-in-the-lab analysis? Maybe its idiot's gold! And much like Pandora's 'box' is truly a jar and not a container, maybe the 'pot' is in reality a bowl! Of path the scientists can't quite get at the pot-of-gold since it is guarded with the aid of a leprechaun, and no scientist is going to admit being thwarted with the aid of a little inexperienced guy (or kidnapped by way of a bit grey one both for that count).
Okay, I could be foolish not to agree with your commentary and to disclaim the fact of rainbows, but its k for clinical skeptics to ignore the rainbow parallel when it comes to UFOs. Eyewitness testimony regarding UFO sightings isn't always really worth the fee of the paper it is published on; images of UFOs are indeed pure Photoshop fakery.
But in reality, UFOs offer up way extra physical proof than the rainbow. Despite that pot-of-gold on the cease of a rainbow legend, rainbows leave at the back of no physical strains; no physiological consequences, and no electromagnetic results; they make no sounds, and so forth. UFOs aren't so hampered. So, if crunch-comes-crunch, the truth of UFOs have plenty greater going for them in terms of bodily evidence than the truth of rainbows. Of course no scientist in their proper mind might show off scepticism of the existence of rainbows even with none bodily evidence backing them up, however with regards to UFOs, it is a different horse of some other coloration - but is it certainly a one-of-a-kind horse, and is it truely of a special hue?
Of route one motive physical scientists receive the fact of the rainbow is that they have got seen one themselves (many maximum probable) and seeing is believing as lengthy because it's they who are doing the seeing. If they themselves had witnessed a UFO event they (and their colleagues) couldn't pick out then I'm certain they would be a good deal greater open and willing to simply accept some other's eyewitness testimony. A bit of a double wellknown there of direction however this is human nature and scientists aren't exempt from that weakness. Unfortunately, UFOs tend to be a rarer commodity than rainbows and therefore witnessed way much less regularly, together with viewings via scientists.
While UFOs have a better bodily evidence quota than rainbows, they also have a better strangeness quota too, which is not to say that rainbows do not have a unusual mythological air of mystery approximately them. I wonder if the scientist who accepts the fact of the rainbow additionally accepts that the rainbow is a bridge to heaven (Asgard) consistent with Norse mythology and made famous within the conclusion to Richard Wagner's first "Ring Cycle" opera "Das Rheingold". Christian mythology has the rainbow as a sign that as a minimum the subsequent time God lays waste to the sector it may not be thru the Big Wet, although I doubt you will discover that in any textbook on optical and atmospheric phenomena. And if you're into cryptozoology, the Australian aborigines have a Rainbow Serpent (which doubles as a writer deity), however alternatively, scientists are not referred to for his or her curiosity into the real life of unknown mega-fauna or polytheistic creator deities** either for that count. In reality, you name the subculture; you will discover a rainbow mythology contained within. Rainbows are related to spirits and demons and all way of omens from the good, to the bad and the ugly that scientists will reject as component and parcel of their notion machine.
So, in which do scientists draw the road? Rainbows - sure; rainbow serpents and rainbow bridges - no. And this distinction is rightly so, IMHO. But when they reject out of hand a phenomenon that genuinely has extra and better evidence than say rainbows (auroras and sprites might be other cases in point) then eyebrows must be raised and questions requested - like please give an explanation for your good judgment.
While on the problem of things mythological, allow's move reminiscent of the celebrities and planets and other celestial objects. There's a huge mythology from many historical cultures that generally is going hand-in-hand with how those celestial items and night time sky patterns came to be. Astronomers do not aid those tall tales both considering they have got different greater scientific theories that explain the origins of stars and constellations. Still, its competing theories of a way to account for say, the Pleiades famous person cluster. Once upon a time it turned into Zeus. Today it is astrophysics. Who's to say considering that neither scenario may be subjected to a definitive WE REQUIRE PROOF slab-in-the-lab test.
By the way, as a very last counterattack, I have not but visible any SETI scientist provide you with proof high quality on ET, so IMHO it is nevertheless a tied ball game. But rather than have opposing groups, SETI scientists might also as properly take a look at UFOs as properly when you consider that SETI to this point has a batting common of zero. Perhaps that's what comes from scientists setting all their ET eggs in only the SETI basket.
*And the Sun can't have sunspots due to the fact all of us understand that the Sun is best; meteorites cannot exist seeing that we all know stones can't fall from the sky;
**Though faith inside the reality of God is hardly ever unknown to exist in some bodily scientists, even though like stars and rainbows, they can't placed God at the slab of their lab either. Somehow the WE REQUIRE PROOF standards don't remember in this case.
Cancer survival rates could be greatly improved if scientists are successful in developing microscopic medical weapons that obliterate cancerous cells.
Nanomachines may be tiny – 50,000 of them would fit across the diameter of a human hair – but they have the potential to pack a mighty punch in the fight against cancer.

Researchers at Durham University in the UK have used nanobots to drill into cancer cells, killing them in just 60 seconds.
They are now experimenting on micro-organisms and small fish, before moving on to rodents. Clinical trials in humans are expected to follow and it is hoped that the results may have the potential to save millions of lives.
The mechanics of nanobots
These minute molecules have components that enable them to identify and attach themselves to a cancer cell.
When activated by light, the nanobots’ rota-like chain of atoms begin to spin at an incredible rate – around two to three million times per second. This causes the nanobot to drill into the cancer cell, blasting it open.
The study is still in its early stages, but researchers are optimistic it has the potential to lead to new types of cancer treatment.
Dr Robert Pal, of Durham University, said: “Once developed, this approach could provide a potential step change in noninvasive cancer treatment and greatly improve survival rates and patient welfare globally.”
Nanobots in our veins
The destructive properties of the nanobots make them perfect for killing cancer cells. But the technology can also be used to repair damaged or diseased tissues at a molecular level.
In the future, these nanomachines could essentially patrol the circulatory system of the human body. They could be used to detect specific chemicals or toxins and give early warnings of organ failure or tissue rejection.
Another potential function may involve taking biometric measurements to monitor a person’s general health.
Searching for oil
The medicinal advantages of nanobots are clear to see, but industry might also benefit from the technology.
Oil and gas is one example. The idea is that nanobots could be injected into geologic formations thousands of feet into the earth. Changes to the chemical make-up of the machines would point to the location of reservoirs.
The crater lakes at the summit of Kelimutu volcano in Indonesia change colors from day to day. The colors can change from white, green, blue and brown to black.
Landsat 8 views from space of the 3 lakes at the summit of the Kelimutu volcano in Indonesia, known to change color unpredictably, via NASA Earth Observatory.
This composite image of Kelimutu volcano in Indonesia was the NASA Earth Observatory Image of the Day for July 6, 2018. It called them volcanic mood rings and explained:
From milky white to vibrant turquoise to blood red, the three lakes at the summit of the Kelimutu volcano are known to unpredictably change color – a phenomenon unique to this volcano on the Indonesian island of Flores.
These images, acquired by the Operational Land Imager on Landsat 8, show the various colors of the crater lakes on three different days. All three crater lakes appear on the crest of the volcano with the eastern two lakes sharing a common crater wall … Depending on when you visit, the colors can range from white, green, blue, brown or black. In 2016, the lakes changed colors six times.
Local folklore contends the lakes are the resting place for the dead, and that a person’s good or bad deeds in life determine which of the three lakes becomes his or her resting place.
Science says the changing colors of Kelimutu’s summit lakes are caused by fumaroles, or volcanic vents that release steam and gases, producing upwelling in the lakes and bringing denser, mineral-rich water from their bottoms to their surfaces. NASA Earth Observatory explained:
All of the lakes contain relatively high concentrations of zinc and lead.
While minerals play a part in the coloring, another key factor is the amount of oxygen present in the water. Like your blood, these lake waters appear bluer (or greener) when low in oxygen. When they are oxygen-rich, they appear blood red or even cola black.
Bottom line: NASA Earth Observatory Image of the Day for July 6, 2018, showing the three variously colored lakes at the summit of Kelimutu volcano in Indonesia.
Whether you find flocks of birds terrifying or mystifying, you can objectively say that they’re pretty skilled at not ramming into each other mid-flight.
Looking to the success of birds, group of European researchers has successfully enabled a group of 30 quadcopters to fly in sync after programming the drones to mimic the flight of a flock of birds.
Dr. Gábor Vásárhelyi, the first author of this new research published on Wednesday in the Science Robotics journal, tells Inverse he believes collective bird movement holds the answer to solving an issue we’ll soon be faced with: Keeping thousands of drones from colliding over our heads. Dr. Agoston E. Eiben, a co-author of the new study, describes their development of drone technology that mimics how birds flock together as “natural computing.”
Here’s how they did it: Researchers spent six years observing pigeons with GPS devices to determine if they could reproduce these aerial formations of the birds with autonomous drones. For drones, mastering synchronized flight may be a crucial first step to mastering real-world delivery routes.
Flight simulation of 30 autonomous drones moving in a confined area at 6 m/s (13.4 mph) using the method developer by Vásárhelyi and his colleagues.
“When the first cars appeared on the streets people were walking in front of them and ringing a bell that cars were coming, but soon there we a diversity of cars moving in coordinated ways throughout cities, something similar is going on with drones,” Vásárhelyi says. “Now, every drone has a single pilot, soon these drones will have such a density in the air that we need to make them able to communicate with each other.”
Realistic simulations of 30-1000 drones flocking in confined environments
Why Drone Delivery Could Be Big Business
This in-air communication is crucial, because of the intense interest in drone delivery as a business. Multi-national companies and startups alike are working to make these services a reality.
The best-known player in the competition to develop delivery drones is probably Amazon: The e-commerce giant makes 1.6 million daily deliveries in the United States, according to one estimate. Even if its future Prime Air service would take care of a quarter of those deliveries, that would be thousands of autonomous drones that would some system to make sure they don’t slam into each other, or anything else.
Drone Delivery Faces Regulatory Obstacles
In March 2016, the Federal Aviation Administration announced that drone registration outnumbered that of airplanes. Standard planes use control centers to coordinate their flights but with so many drones in the sky, it would be impossible to develop a drone-ports to manage them all. Eiben tells Inverse that each drone will need to have the capability of managing itself.
There needs to be underlying, decentralized software to make sure [drones] don’t collide.”
“We have a massive e-commerce industry. If drone delivery gets big than urban environments will be a major hurdle for various drones sharing the same airspace,” says Eiben, a professor of computer science at VU University Amsterdam. “There needs to be underlying, decentralized software to make sure they don’t collide, it’s core to this advancement.”
Eiben explained drone delivery has been held back by the “reality gap” — or the rift between what works in simulation and what works in real life. Previous studies found that even though solutions seemed promising on the computer screen, testing them on hardware would yield disappointing results. But not this time.
Vásárhelyi and his other colleagues built their own custom drones, implemented their bird-inspired models, which were refined by Eiben’s software expertise and dunked on prior research. They managed to get 30 quadcopters to self-organize themselves using GPS modules, just like our feathery, avian friends. They managed to pull this off by not only determining the distance to the closest drone but also calculate the speed and acceleration of their fellow robots.
But don’t worry, this isn’t the beginning of some futuristic version of Alfred Hitchcock’s The Birds. Vásárhelyi sees great potential for this type of technology to be used for search and rescue missions, as well as enabling drone deliveries.
So if the day comes where quadcopters are delivering parcels right to your window sill, remember to thank the birds. The OG drones.
Researchers have discovered what appears to be a cache of diamonds hidden in the Earth’s mantle. This suggests that, at a geological scale, diamond might not be the exotic mineral we once thought it to be — they may be quite common, though not easily accessible.

Earthquakes and diamonds
The world’s deepest borehole goes down 12.262 kilometers (40,230 ft). How is it then that we know so much about the depths of the Earth, which boasts an average radius of over 6,300 km? As is so often the case, scientists have gathered a trove of data which enabled them to infer many things beyond sight — in this case, of the Earth’s interior properties.
Seismometers record the ground movement on a seismograph. Based on the wiggles of the seismograph, certain pieces of information can be drawn, particularly about the nature of the ground the wave has passed through. Of course, this is a great simplification and the seismogram analysis process is much more intricate, often involving a great deal of complexity and mathematical algorithms. You can pick up simpler things, like where the earthquake epicenter was and how much energy the earthquake had, or use the data for complex things — like constructing an image of what the Earth’s interior might look like.

For decades, agencies such as the USGS, universities, and research groups have been keeping track of this seismic activity. Among many other things, scientists have noticed an intriguing anomaly: the velocity of some seismic waves in some areas could not be explained with our existing knowledge of the Earth’s structure.
In this particular case, an MIT team aimed to identify the composition of so-called cratonic roots that might explain the spikes in seismic speeds. They concluded that the reason for this anomaly is diamonds.
“This shows that diamond is not perhaps this exotic mineral, but on the [geological] scale of things, it’s relatively common,” says Ulrich Faul, a research scientist in MIT’s Department of Earth, Atmospheric, and Planetary Sciences. “We can’t get at them, but still, there is much more diamond there than we have ever thought before.”
Cratons
Cratons whose ancient rocks are widely exposed at the surface are typically called shields. If the ancient rocks are largely overlain by a cover of younger rocks, the craton is generally referred to as a platform.
Image credits: USGS.
The Earth’s crust made out of mobile, dynamic tectonic plates. We don’t see that because the movement is essentially unnoticeable at a human scale, but at a geological scale, tectonic plates move about quite a lot. Most tectonic plates’ movement is on the scale of a few centimeters per year.
Cratons are very old and stable parts of the Earth’s tectonic crust. Most cratons on Earth have survived cycles of merging and rifting of continents, and are typically located at the interior of tectonic plates. They have a thick crust and deep lithospheric “roots” that can extend several hundred kilometers into the Earth’s mantle.
Cratons are also colder and less dense than the surrounding mantle, which means that they would yield slightly faster seismic waves — but this alone can’t entirely account for the speed anomaly. So there must be something else.
“The velocities that are measured are faster than what we think we can reproduce with reasonable assumptions about what is there,” Faul says. “Then we have to say, ‘There is a problem.’ That’s how this project started.”
In order to solve this conundrum, Faul and colleagues started assembling virtual rocks which could theoretically exist at the temperature and pressure conditions in those parts of the mantle. They then calculated how fast seismic waves would pass through these structures, to see if this would fit the observed seismic data.
They found that the data would be best explained by a craton rock composition of 1 to 2 percent diamond. This would translate to about quadrillion tons of diamond.
In a way, this makes a lot of sense. We know that diamonds are forged deep in the bowels of the Earth, in high-pressure, high-temperature environments. The only reason why we’re able to find diamonds is that they’re brought closer to the surface by volcanic eruptions which act like “pipes” — bringing them to the surface, where we at least have a chance of finding them.
Of course, it’s important to note that Faul and colleagues found no direct evidence that the craton roots do contain diamonds, it’s just that this explanation seems to fit best. But this line of thinking has brought us so far, so at least for now, it seems convincing enough.
“It’s circumstantial evidence, but we’ve pieced it all together,” Faul says. “We went through all the different possibilities, from every angle, and this is the only one that’s left as a reasonable explanation.”

At a first glance, not much is going on in this image — just some yellowish noise on a blue-green background. But this photo from ESA’s Herschel Space Observatory shows much more than you’d think: every yellowish speck is a galaxy.
This is the North Galactic Pole, an area which covers some 180 square degrees of the sky and features a galaxy-rich cluster known as the Coma Cluster, which contains at least 1,000 points of light (read: galaxies).

Just like on Earth, astronomers define observations using a coordinate system — but unlike the XYZ coordinate systems you might be more familiar with, they use a spherical coordinate system. In the former, a point is described by its X, Y, and Z coordinates.
A visual depiction of the spherical coordinate system for a point P. The polar angle is in blue, the azimuthal angle in red.
In a spherical system, a point is also described by three coordinates but, in this case, it’s the radial distance of that point from a fixed origin, the polar angle, and the azimuth angle. It can be a bit weird to wrap your head around, but it can be much easier to navigate astronomical observations.
So here, we have the North Galactic Pole, which lies far from the cluttered disc of the Milky Way and offers a good view of the distant Universe beyond our home galaxy.

The image above was taken at a wavelength of 250 μm, in the infrared range (the human visible range is generally within 0.4 – 0.7 μm). It was taken using the Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS). Unfortunately, Herschel isn’t active anymore — it functioned from 2009 to 2013, using its instruments to study the sky in the far infrared range.
Aside from making us feel incredibly small and showing us just how puny our struggles really are, these pictures also help astronomers to estimate how many galaxies there are in the Universe. Recent surveys have estimated that number to be around 20 trillion, which is 20 times more than previous estimates gathered using the Hubble telescope. All these galaxies are packed with billions of stars, which can also host planets just like Earth.
Jupiter is definitely the most popular planet in the Solar System — at least as far as moons are concerned.

In Roman mythology, Jupiter (Zeus for the Greek) is quite the player. Never content to let a pretty mortal get by without his (usually unwanted) affections, the mythos abounds with the thunder god’s, um, transgressions. Which, quite understandably, gets everyone in deep trouble with his wife Juno (Hera in Greek mythology).
New research shows that the planet Jupiter is also quite happy to collect consorts. Twelve new moons have been discovered orbiting it, bringing the gas giant’s total collection to an impressive 79 moons — more than any other planet in the Solar System. One of these moons, according to the researchers who made the discovery, is an “oddball” that might help explain how the ochre giant got all of its moons. In a twist of mythological foreshadowing, it likely wasn’t a peaceful process.
The team from the Carnegie Institution for Science (story source) first spotted the moons in the spring of 2017. They weren’t looking for the moons per se — the team was actually looking for very distant objects in the Solar System as part of the hunt for Planet X, nestled somewhere far beyond Pluto. Some of the members involved in this research were actually part of the team that proposed the existence of this planet in the first place.
But back to the moons. As luck would have it, the researchers were simply looking in the right place at the right time to spot the gas giant — so they decided to have a look.
“Jupiter just happened to be in the sky near the search fields where we were looking for extremely distant Solar System objects, so we were serendipitously able to look for new moons around Jupiter while at the same time looking for planets at the fringes of our Solar System,” said team leader Scott Sheppard.
Based on these observations, members of the International Astronomical Union (IAU) calculated the orbits of the recorded bodies — and were surprised to see that they didn’t match any of Jupiter’s known moons.
“It takes several observations to confirm an object actually orbits around Jupiter,” said Gareth Williams, from the IAU’s Minor Planet Center, who was involved in the orbit calulations. “So, the whole process took a year.”

Nine of these bodies are more distant relative to other Jovian moons, and orbit in retrograde — the opposite direction of the planet’s spin. These distant moons form at least three distinct orbital groups; the team believes they’re the remnants of larger bodies that broke apart during past collisions with asteroids, comets, or other moons. They generally take about two years to orbit their host planet.
Two others form a closer group that orbits in the prograde — the same direction as Jupiter’s rotation. Since they both have similar orbital distances and inclinations relative to Jupiter, they’re also likely remnants from a larger moon that since broke apart. They take just shy of a year to orbit Jupiter.
The most surprising moon, however, is the runt of the litter.
“Our other discovery is a real oddball and has an orbit like no other known Jovian moon,” Sheppard explained. “It’s also likely Jupiter’s smallest known moon, being less than one kilometer in diameter.”
This tiny moon has a more inclined orbit and keeps a wider berth to the planet that the prograde group. Its orbit crosses that of the outer, retrograde group, making head-on collisions much more likely between itself and this latter group.
This situation could explain how Jupiter got so many moons. Today, head-on collision would break any of the bodies “down to dust”, Shepard says, and could shatter a larger body into the tiny moons of today. It’s possible then that the current various moon groupings were formed in the distant past through such collisions.
The oddball itself could be all that remains of a much larger prograde moon that impacted with other bodies to create the retrograde group identified by the team. It has yet to be christened, but the name Valetudo (the Roman goddess of health and hygiene and Jupiter’s great-granddaughter) has been suggested.
WETENSCHAP & PLANEETDe wetenschap schenkt ons meestal klare antwoorden, maar roept soms ook extra vragen op. Volgende ontdekkingen doen je waarschijnlijk bedenkelijk met de wenkbrauwen fronsen.
Onderzoekers houden zich normaal zoet met de grote levensvragen. Zo riep Archimedes luidkeels eureka uit eenmaal hij zijn beroemde natuurkundewet neerschreef die verklaart waarom een schip blijft drijven. Newton testte met behulp van een appel uit hoe de zwaartekracht werkt en Thomas Edison gaf ons meer dan enkel kaarslicht: de gloeilamp.
Natuurlijk is het vandaag de dag wat moeilijker om een belangrijk onopgelost vraagstuk te vinden. Dus houden wetenschappers zich bezig met bedenkelijke experimenten met even bizarre resultaten. Nieuwsgierigheid is toch de motor van de wetenschap?
1. Één kilogram veren
“Wat weegt meer? Een kilogram lood of een kilogram veren?” Het is een klassieke instinker. Logischerwijs zouden beide opties evenveel wegen. Het hoopje pluimen is waarschijnlijk wel een pak groter.
Toch bewees een proef het tegendeel. Onderzoekers blinddoekten enkele personen waarna ze een doos gevuld met lood en een doos gevuld met hetzelfde gewicht aan veren moesten optillen. Wanneer men hen vroeg om de zwaarste doos aan te duiden, selecteerden de meeste proefpersonen de doos met veren.
2. Van vetberg naar biodiesel
In 2017 werd Londen geteisterd door een gigantische blokkade van de rioleringen. Bijna 250.000 kilogram samengekoekt vet, luiers, toiletdoekjes en ander afval had zich opgehoopt en verhinderde de goede werking het rioolbeheer.
Eenmaal de bevoegde instanties de reusachtige berg afval verwijderden, gingen de beelden de wereld rond. Het prikkelde niet enkel de nieuwsgierige kijker maar ook enkele wetenschappers. Ze beweerden dat ze de vetberg voor andere doeleinden konden gebruiken. Ze besloten de berg in kleinere stukken te hakken en het afval van het vet te scheiden. Dat vet zetten ze uiteindelijk om in biodiesel, een milieuvriendelijkere brandstof dan diesel en benzine. Zo’n 350-tal bussen konden een dag rondrijden met het resultaat van het experiment.
3. De kracht van pinguïnuitwerpselen
Wanneer pinguïns poepen, doen ze dat gewoon vanuit hun nest. Dat lijkt misschien niet zo netjes. Toch bevuilen de zeevogels hun slaapplaats niet. Ze bewegen hun achterste simpelweg naar de rand van het nest waarna ze met enorm veel druk hun uitwerpselen naar achter spuiten. De druk die daarbij komt kijken is veel groter dan die bij de menselijke ontlasting. Je zou er als ongelukkige pinguïn maar net achter staan.
4. Blinkende vrouwen door anticonceptiepil
In 1994, toen de anticonceptiepil een beetje beter in de markt lag, onderzochten wetenschappers wat voor ’n zichtbaar effect het pilletje had op vrouwen. Zo ondervonden ze dat vrouwen die de pil innamen feller blonken dan vrouwen die dat niet deden.
Al lijkt het niet meteen geloofwaardig, recenter onderzoek bewijst dat een anticonceptiepil een invloed uitoefent op 150 verschillende biologische functies. Eentje daarvan is waarschijnlijk verantwoordelijk voor een vettere en glimmende huid.
5. Een vinger in de poep tegen het hikken
In de jaren ’90 kon een zestigjarige man maar niet stoppen met hikken. Een vervelend kwaaltje vond hij. Dus bezocht hij zijn dokter. Die dacht dat het misschien te wijten was aan de neussonde die zijn patiënt moest dragen. Maar ook na het verwijderen van de sonde stopte het hikken niet. Vervolgens schreef hij de oude man enkele medicijnen voor. Tevergeefs.
Tenslotte zocht de wanhopige dokter zijn antwoord bij een eerder gerapporteerd geval. Daar werd de patiënt van zijn lijden verlost met behulp van een prostaatmassage. Kortom, de dokter stak zijn vinger in de poep van zijn patiënt en vreemd genoeg kon dat soelaas bieden.
6. De gevaren van een grasmaaier
Heb je jezelf al eens ooit pijn gedaan tijdens het grasmaaien? Dan ben je niet alleen. In 1988 ondervonden enkele onderzoekers dat maar liefst 70.000 van de verwondingen in de Verenigde Staten te wijten waren aan grasmaaiers. Daarvan ging het bij vijf procent om een pijnlijke wonde aan het oog.
Al denk je dat het er misschien op vooruit ging omdat grasmaaiers heel wat hipper zijn, nieuwe studies bewijzen het tegendeel. Intussen blijkt de grasmaaier verantwoordelijk te zijn voor 75 doden per jaar. Ook het aantal gewonden wordt alleen maar groter. Meestal gaat het om verwonde vingers of handen.
7. Kleur van medicatie doet er toe
Nog voordat we een pilletje innemen, vraagt ons brein zich al of het zal werken of niet. De kleur en vorm ervan beïnvloeden het verdict. Blauwe medicatie wordt als kalmerend waargenomen. Pillen met een rode en oranje kleur hebben een tegengesteld effect. Van zulke pillen verwacht men een stimulerend effect en die verwachting wordt meestal ingelost, zelfs bij placebo’s. Gele varianten hebben dan weer een antidepressieve werking en heldere kleuren blijken over het algemeen een beter effect te hebben dan neutrale kleurtjes.
8. Viagra verlost hamsters van hun jetlag
Hoe ze in godsnaam op het idee kwamen, weet niemand. In 2007 vermoedden enkele vernuftige onderzoekers dat Viagra een handje kon helpen bij het verwerken van hamsters hun jetlag. Ze wijzigden de tijdzone en simuleerden een verschil van zes uur. Na het toedienen van Viagra bleken de hamsters tot vijftig procent sneller te herstellen van het tijdsverschil dan de hamsters die geen hulp kregen. Of de sekspil eenzelfde invloed heeft op de mens moet nog onderzocht worden.
9. Honden poepen enkel noord of zuid
Let eens op de manier waarop je hond poept. Tenslotte toont onderzoek aan dat de dieren steevast naar het noorden of het zuiden kijken wanneer ze hun uitwerpselen lozen. Blijkbaar doen ze dat omdat ze zich bewust zijn van het magnetisch veld van onze aarde. En ze zijn niet alleen. Ook koeien en herten houden er rekening mee. Leg gerust een kompas naast je trouwe viervoeter wanneer hij nog eens hurkt.

The Hunt for Earth’s Deep Hidden Oceans
The Hunt for Earth’s Deep Hidden Oceans
Water-bearing minerals reveal that Earth’s mantle could hold more water than all its oceans. Researchers now ask: Where did it all come from?
A couple hundred pebble-size diamonds, plucked from Brazilian mud, sit inside a safe at Northwestern University. To some, they might be worthless. “They’re battered,” said Steve Jacobsen, a mineralogist at Northwestern. “They look like they’ve been through a washing machine.” Many are dark or yellow, far from the pristine gems of jewelers’ dreams.
Yet, for researchers like Jacobsen, these fragments of crystalline carbon are every bit as precious — not for the diamond itself, but for what is locked inside: specks of minerals forged hundreds of kilometers underground, deep in Earth’s mantle.
These mineral flecks — some too small to see even under a microscope — offer a peek into Earth’s otherwise unreachable interior. In 2014, researchers glimpsed something embedded in these minerals that, if not for its deep origins, would’ve been unremarkable: water.
Not actual drops of water, or even molecules of H20, but its ingredients, atoms of hydrogen and oxygen embedded in the crystal structure of the mineral itself. This hydrous mineral isn’t wet. But when it melts, out spills water. The discovery was the first direct proof that water-rich minerals exist this deep, between 410 and 660 kilometers down, in a region called the transition zone, sandwiched between the upper and lower mantles.
Since then, scientists have found more tantalizing evidence of water. In March, a team announced that they had discovered diamonds from Earth’s mantle that have actual water encased inside. Seismic data has also mapped water-friendly minerals across a large portion of Earth’s interior. Some scientists now argue that a huge reservoir of water could be lurking far beneath our feet. If we consider all of the planet’s surface water as one ocean, and there turn out to be even a few oceans underground, it would change how scientists think of Earth’s interior. But it also raises another question: Where could it have all come from?
Water World
Without water, life as we know it would not exist. Neither would the living, dynamic planet we’re familiar with today. Water plays an integral role in plate tectonics, triggering volcanoes and helping parts of the upper mantle flow more freely. Still, most of the mantle is relatively dry. The upper mantle, for instance, is primarily made of a mineral called olivine, which can’t store much water.
But below 410 kilometers, in the transition zone, high temperatures and pressures squeeze the olivine into a new crystal configuration called wadsleyite. In 1987, Joe Smyth, a mineralogist at the University of Colorado, realized that wadsleyite’s crystal structure would be afflicted with gaps. These gaps turn out to be perfect fits for hydrogen atoms, which could snuggle into these defects and bond with the adjacent oxygen atoms already in the mineral. Wadsleyite, Smyth found, can potentially grab onto lots of hydrogen, turning it into a hydrous mineral that produces water when it melts. For scientists like Smyth, hydrogen means water.
Deeper in the transition zone, wadsleyite becomes ringwoodite. And in the lab, Jacobsen (who was Smyth’s graduate student in the 1990s) would squeeze and heat bits of ringwoodite to mimic the extreme conditions of the transition zone. Researchers doing similar experiments with both wadsleyite and ringwoodite found that in the transition zone, these minerals could hold 1 to 3 percent of their weight in water. Considering that the transition zone is a roughly 250-kilometer-thick shell that accounts for about 7 percent of Earth’s mass (by comparison, the crust is only 1 percent), it could contain several times the water of Earth’s oceans.
These experiments, however, only gauge water capacity. “It’s not a measurement of how wet the sponge is, it’s a measurement of how much the sponge can hold,” said Wendy Panero, a geophysicist at Ohio State University.
Neither were the experiments necessarily realistic, since researchers could only test lab-grown ringwoodite. Apart from a few meteorites, no one had ever seen ringwoodite in nature. That is, until 2014.
Tantalizing Clues
While soccer fans converged on Brazil for the 2014 World Cup, a small group of geologists headed to the farmlands around Juína, a city almost 2,000 kilometers west of Brasilia. They were on the hunt for diamonds that had been panned from local rivers.
As diamonds form in the heat and high pressure of the mantle, they can trap bits of minerals. Because diamonds are so tough and rigid, they preserve these mantle minerals as they’re blasted to the surface via volcanic eruptions.
The researchers bought more than a thousand of the most speckled, mineral-filled crystals. One of the scientists, Graham Pearson, took several hundred back to his lab at the University of Alberta, where, inside one particular diamond, he and his colleagues discoveredringwoodite from the transition zone. Not only that, but it was hydrous ringwoodite, which meant it contained water — about 1 percent by weight.
“It’s an important discovery in terms of plausibility,” said Brandon Schmandt, a seismologist at the University of New Mexico. For the first time, scientists had a sample of the transition zone — and it was hydrated. “It’s definitely not crazy, then, to think other parts of the transition zone are also hydrated.”
But, he added, “it would also be a little crazy to think that one crystal represents the average of the entire transition zone.” Diamonds, after all, form only in certain conditions, and this sample might come from a uniquely watery place.
To see how widespread hydrous ringwoodite could be, Schmandt teamed with Jacobsen and others to map it using seismic waves. Due to convection, hydrous ringwoodite can sink, and as it drops below the transition zone, the rising pressure wrings water out, causing the mineral to melt. Just beneath the transition zone where mantle material is descending, these pools of molten minerals can abruptly slow seismic waves. By measuring seismic speeds under North America, the researchers found that, indeed, such pools appear common below the transition zone. Another studymeasuring the seismic waves under the European Alps found a similar pattern.
Abundant mantle water got yet another boost in March when a team led by Oliver Tschauner, a mineralogist at the University of Nevada, Las Vegas, discovered diamonds that contain actual pieces of water ice — the first observation of freely existing H2O from the mantle. The samples might say more about the wet conditions that formed the diamond than the existence of any ubiquitous reservoir. But because this water — a high-pressure form called ice-VII — was found in a variety of locations across southern Africa and China, it could turn out to be relatively widespread.
“A couple years from now, we’ll find ice-VII is much more common,” said Steve Shirey, a geologist at the Carnegie Institution for Science. “It’s telling us we have the same story that hydrous ringwoodite is telling us.”
But if the story is that the mantle is brimming with water, the cliffhanger leaves us wondering how it all got there.
Watery Origins
According to the standard tale, Earth’s water was imported. The region around the sun where the planet formed was too hot for volatile compounds like water to condense. So the nascent Earth started out dry, getting wet only after water-rich bodies from the distant solar system crashed into the planet, delivering water to the surface. Most of these were likely not comets but rather asteroids called carbonaceous chondrites, which can be up to 20 percent water by weight, storing it in a form of hydrogen like ringwoodite.
But if there’s a huge stockpile of water in the transition zone, this story of water’s origin would have to change. If the transition zone could store 1 percent of its weight in water — a moderate estimate, Jacobsen said — it would contain twice the world’s oceans. The lower mantle is much drier but also voluminous. It could amount to all the world’s oceans (again). There’s water in the crust, too. For subduction to incorporate that much water from the surface at the current rate, it would take much longer than the age of the planet, Jacobsen said.
If that’s the case, at least some of Earth’s interior water must have always been here. Despite the heat in the early solar system, water molecules could have stuck to the dust particles that coalesced to form Earth, according to some theories.
Yet the total amount of water in the mantle is a highly uncertain figure. At the low end, the mantle might hold only half as much water as in the world’s oceans, according to Schmandt and others.
On the high end, the mantle could hold two or three times the amount of water in the oceans. If there were much more than that, the additional heat of the younger Earth would have made the mantle too watery and runny to fracture the continental plates, and today’s plate tectonics may never have gotten started. “If you have a bunch of water in the surface, it’s great,” said Jun Korenaga, a geophysicist at Yale University. “If you have a bunch of water in the mantle, it’s not great.”
But many uncertainties remain. One big question mark is the lower mantle, where extreme pressures turn ringwoodite into bridgmanite, which can’t hold much water at all. Recent studies, however, suggest the presence of new water-bearing minerals dubbed phase D and phase H. Exactly what these minerals are like and how much water they might store remains an open question, Panero said. “Because it is a wide-open question, I think that the water content in the mantle remains open for debate — wide open.”
Measuring Earth’s interior water storage isn’t easy. One promising way is to measure the electrical conductivity of the mantle, Korenaga said. But those techniques aren’t yet as advanced as, say, using seismic waves. And while seismic waves offer a global view of Earth’s interior, the picture isn’t always clear. The signals are subtle, and researchers need more precise data and a better understanding of the properties of more realistic mantle material, instead of just ringwoodite and wadsleyite. Those two minerals constitute about 60 percent of the transition zone, the rest being a complex mix of other minerals and compounds.
Finding more diamonds with hydrous minerals would help, too. In Jacobsen’s lab, that job falls to graduate student Michelle Wenz. For each diamond, she uses powerful X-rays at Argonne National Laboratory to map the location of every mineral speck, of which there may be half a dozen. Then, to identify the minerals, she blasts X-rays onto each bit and measures how the rays scatter off its crystal structure. Of the hundreds of diamonds in the lab, all from Brazil, she’s gone through about 60. No water yet.
Water or not, she said, these capsules from the deep are still amazing. “Each one is so unique,” she said. “They’re a lot like snowflakes.”
Correction:This article was revised on July 11, 2018, to correct a typographical error; it is the mantle, not the ocean, that could hold two or three times the amount of water in the oceans.
De zoektocht naar verborgen oceanen in het onbereikbare binnenste van de aarde. Waar komt dit water vandaan?
De zoektocht naar verborgen oceanen in het onbereikbare binnenste van de aarde. Waar komt dit water vandaan?
Diamanten uit het onbereikbare binnenste van de aarde blijken water te bevatten. Dat lees je goed: water.
Als de mineralen worden gesmolten, komt er water uit tevoorschijn. Deze waterrijke mineralen bevinden zich op een diepte van 410 tot 660 kilometer in de mantel en mogelijk nog veel dieper.
Sommige wetenschappers stellen dat zich ver onder onze voeten een gigantische watervoorraad bevindt.
Belangrijke rol
Als je al het oppervlaktewater op aarde als één oceaan ziet, dan kunnen zich onder de grond met gemak enkele oceanen bevinden. De vraag is nu waar al dit water vandaan komt.
Water speelt een belangrijke rol bij platentektoniek, vulkaanuitbarstingen en zorgt ervoor dat delen van de mantel zich vrijer kunnen bewegen.
Het bovenste gedeelte van de mantel bestaat vooral uit olivijn, een mineraal dat weinig water kan opslaan.
Maar vanaf een diepte van 410 kilometer verandert olivijn als gevolg van hoge temperaturen en druk in wadsleyiet, dat veel gemakkelijker water opslaat.
Meerdere keren
Op nog grotere diepte wordt wadsleyiet ringwoodiet. Deze mineralen bestaan voor zo’n één tot drie procent uit water.
Aangezien het gebied waarin ze voorkomen zeven procent van de massa van de aarde uitmaakt, kan het meerdere keren de totale hoeveelheid van al het water op aarde bevatten.
In maart ontdekte Oliver Tschauner van de Universiteit van Nevada in Las Vegas diamanten uit de mantel die stukjes waterijs bevatten. Het was de eerste aanwijzing dat H2O voorkomt in de mantel.
Sneeuwvlokken
Als de mantel vol water zit, is water van de aarde niet van buitenaf naar onze planeet gekomen. Dat water moet er dan altijd al zijn geweest.
Studente Michelle Wenz doet in het laboratorium onderzoek naar de diamanten. “Ze zijn allemaal zo uniek,” zei ze. “Ze lijken erg op sneeuwvlokken.”
At first, ancient Egyptians buried all of their dead, regardless of social status, in pits in the sand that covers much of their country. The dry air quickly and naturally preserved these bodies, giving Egyptian religions support for their beliefs in the afterlife. Unfortunately, animals had no such respect for the human dead, so the bodies were later placed in coffins or sarcophagi, which protected them from beasts but not from decomposition. Somewhere around 2800 BCE, a type of artificial mummification began to be developed and tested, using oils and minerals and techniques that have mystified and baffled those trying to duplicate them.
Until now.
At a press conference in Cairo, Egypt’s Ministry of Antiquities announced that German and Egyptian archeologists led by Ramadan Badry Hussein have uncovered an ancient laboratory or workshop dating back to the Saite-Persian period (664-404 BCE) which contains fragments of mummy cartonnages (funeral masks), canopic jars (used for storing human organs removed before mummification) and clay and glazed ceramic cups (pictures here). Even more exciting to Hussein was the discovery of the ingredients and possible measurements for making the secret embalming fluids.
“This [discovery] is so important as it’s extensive. We have oils and measuring cups – all of them are labelled … from this we can find the chemical composition of the oils and discover what they are.”
Set of canopic jars
The laboratory was located next to a 30 meter (98 foot) shaft filled with the end results – mummies. On one of these mummies they found something nearly as significant as the workshop – a gilded silver mask belonging to a priest. Only a handful of these masks covered with precious metals have been found due to looting.
That brings us to how the mummy lab was found in the first place. The Saqqara necropolis of Memphis was last excavated in 1900 but was looted in 2011 during Egyptian protests. It was reopened in 2016 as part of Egypt’s push to use archeology to increase tourism. Artifacts from the discovery of the mummy lab are already on display at the Grand Egyptian Museum, which is still under construction.
Is this push to increase Egyptian tourism through mummies the new looting? Despite warnings, archeologists plan to open a giant mysterious sarcophagus discovered in Alexandria. Researchers are also going back to previously-investigated tombs and sites to search again. Is archeology and history being pushed aside in the name of money? Peru seems to be making an attempt to protect its mummies – real or otherwise – and the World Congress on Mummy Studies is pushing for the same in other countries. Can the mummy workshop at least be protected until its secrets are studied by scholars?
Or is this just another example of why we can’t have nice things?
I founds some mind-blowing alien structures in this large moon photo from the Univ of Arizona index controlled by the USGS and NASA. The most remarkable thing I found was an emerald green dome over a crater. Reminds me of the Emerald City from the Wizard of Oz. There were also two large black shiny domes over craters not far away. I'm not sure how astronomers around the world have ignored such discoverers, but from my research I have learned that NASA has donated a lot of money to observatories around the world, probably to control their research and their released findings. Its up to us, the public to release the truth about the existence of aliens. The truth is...every planet and moon in our solar system has had alien life upon it or within it. Scott C. Waring

Large “Mythological” Fire Bird Spotted Near Yellowstone
Large “Mythological” Fire Bird Spotted Near Yellowstone
A strange colorful bird has been spotted on the Grand Teton National Park live webcam just days after a highly popular area near Jenny Lake in Grand Teton National Park located near the Yellowstone National Park has been closed to the public for the immediate future due to concerns over expanding cracks and fissures in a large rock formation.
While Yellowstone seems to be in a perpetual state of unrest with its Steamboat geyser that has erupted for the 11th time since March and now the expanding cracks and fissures at the Grand Teton National Park the appearance of this colorful bird that resembles the mythological fire bird is at least odd.
The fire bird also called as a phoenix is a sacred fire bird found in the mythologies of many cultures and described as a large magical glowing bird with majestic plumage that glows brightly emitting red, orange, and yellow light, like a bonfire that is just past the turbulent flame.
The fire bird can be seen at around the 2.08 mark in the video and according to the ancient legend the fire bird comes from a faraway land which is both a blessing and a bringer of doom.
Roads have always seemed to attract about them tales of the strange and unusual. They push out, further and further ahead of us, their destinations not visible, mysterious, as the landscape rushes by us, sometimes bringing with it bizarreness. It is perhaps this almost primal sense of oddness that has spawned countless tales of haunted roads, inhabited by all manner of strange entities and apparitions. One feature of some spooky haunted roads are ghost lights, also called spook lights, dancing and twirling in the dark to baffle and amaze, and sometimes they seem to be far from harmless.
Some malevolent spook lights seem to be linked to some sort of phantom motorists, and perhaps one of the more well-known of these is said to prowl a rural road in Switzerland, in St. Johns County, Florida, in the United States. Here there is a modest little road called Greenbriar Road, which runs just east of the main town, and there have for years been tales of a rather aggressive spook light that stalks vehicles that dare to drive along here at night. The enigmatic light is typically said to look just like a motorcycle headlight, which will pull up behind cars and steadily catch up no matter how fast one goes, growing ever larger in the rear view mirrors of the startled drivers.
The light of Greenbriar Road will then either chase the car until it is gone, or bizarrely perch itself atop the vehicle, sort of piggybacking the car for some distance before blinking out of existence as if it were never there at all. In some cases the mysterious light has even been blamed for causing crashes along this lonely stretch of road. The most common origin story for this mysterious light is that it is the wraith of a doomed motorcyclist who died along the road when he was decapitated after running into a telephone pole wire, and that he now terrorizes the stretch upon which he met his fate, with only the headlight of his phantom bike visible. One witness named Todd M. gave an account on the site Weird U.S. thus:
A few years ago I went to see Greenbriar Road at night with three of my friends. We had heard the stories about that light that people see and we wanted to see it. We drove up and down the road for like forty-minutes trying to see something but never saw anything until we got ready to leave. My friend Tom was driving and he looked in the rear view mirror and said what is that? We looked behind us and there was the headlight of a motorcycle coming up fast. We slowed down a little and thought that the biker would pass us but then just as it got right behind us about a hundred feet the light went out. There was no motorcycle or anything. We turned around and went back but didn’t see anything. I really think we saw a ghost biker of that guy that was killed on his motorcycle on that road.
The malignant Greenbriar ghost light is so well-known in the area that it has been the target of paranormal investigations and even scientific studies and police investigations trying to find a rational explanation for what people are seeing, but no explanation has ever been found. Speaking of phantom motorcyclists, there is another similar spook said to haunt a remote stretch of road winding through the rural farming community of Exeter, in Tulare County, California, which is supposedly the stomping ground of a similar ghost.
In this case, in the 1950s a group of friends allegedly decided to play a prank on one of their friends by stretching out some rope across a narrow road called Bardsley road, in the Fresno Valley, after which they lied in wait for their motorcycle riding pal to come cruising by on his way home from work. The plan was for the rope to just hit him in the chest and knock him off his bike, which was pretty mean but they certainly didn’t intend to seriously hurt him, certainly not kill him.
The story goes that the rider came along the darkened road as expected and hit the rope just as expected. What wasn’t expected was that the rope would be too high and lop his head clean off to go rolling across the pavement. In the aftermath of the gruesome accident, people started occasionally claiming to see a bright light shooting up and down the road, sometimes accompanied by the sound of a motorcycle engine, and with the full apparition of a headless rider visible as well. Motorists and people walking along the road at night have also told of being followed or even chased by the phantasm motorcyclist, and it is believed that if you encounter the rider you will be cursed to be in an accident yourself.
Adding to these a is headless rider is said to prowl Creek Road of Ojai, California, apparently riding a vintage 1940s motorcycle and appearing as a glowing light at first, often pulling up next to motorists to bang on their vehicles or chasing them. Interestingly, Creek Road is ground zero for all manner of ghostly phenomena and high strangeness, including at least two phantom horse riders, numerous apparitions, a smoking, horribly burned and disfigured entity called the Char Man, and even a supposed vampire, making a headless motorcycle rider actually one of the less bizarre tales from this place. For more on phantom motorcyclists, you can read my article on this phenomenon here.
Other sinister spook lights seem to be malevolent spirits or even possibly demons. Located out just northeast of Jacksonville, Florida, is St. George Island, which is home to a historic sugar cane, cotton, and corn plantation from the slave days called Kingsley Plantation, established by a Zephaniah Kingsley in 1813. The original plantation would quickly grow until Kingsley owned around a total of 32,000 acres of land and employed about 200 slaves. Despite having so many slaves, Kingsley was known for being a very lax and kind master, allowing his workforce to basically do whatever they wanted when they were off duty, and they were allowed to sell any crafts they made on their own time. Kingsley even married one of his slaves, Ana Madgigine Jai, who would go on to take a prominent management role on the plantation, own her own land, and end up being one of the richest women in the state.
Although conditions were much better for slaves on the Kingsley plantation than they were elsewhere, there was some amount of tragedy on the plantation nevertheless. At some point one of the slaves allegedly took to beating and raping other female slaves, even according to the stories murdering a few and hiding their bodies in the wilderness. When the other slaves got wind of this grim behavior they are said to have gathered a lynch mob to hunt the perpetrator down and hanged on a massive, spooky looking oak tree right in front of the plantation along the main road to the premises, leaving his lifeless body to swing there in the wind. Although Kingsley would move to Haiti along with all of his slaves in 1837, it seems that at least some of them remained, in a macabre sense.
Over the years the Kingsley plantation has come to gather quite a reputation for being intensely haunted, supposedly by the ghosts of those murdered here. One is a woman in white that is frequently spotted roaming around, and has a habit of photo-bombing pictures taken at the locale, while another is an unearthly screaming or wailing that supposedly emanates from the old abandoned well on the property, said to be from a victim of the crime spree whose body was unceremoniously dumped down there in the darkness.
Kingsley Plantation
However, one of the most frightening of the spirits of the old Kingsley Plantation is supposedly the vindictive spirit of the slave murderer himself, who terrorizes the plantation’s creepy and rugged unpaved road. This particularly malicious spirit typically takes the form of two malevolent, angry looking red lights, said to be his glowing eyes, earning the phantom the name “Old Red Eyes.” These lights will supposedly appear behind cars right about at the old oak tree and chase them, in some reports even relentlessly attacking them. One report of an encounter with Old Red Eyes was described by a witness thus:
I’ve saw Old Red Eye several years ago. I have a friend that lives just off that road and had taken him home from Jacksonville one night. It was about midnight and after dropping him off, I was driving back down that road to the hard road and looked in the side mirror on my car and saw two red lights. At first I thought it was the tail lights of another car but they were too close together. I slowed down a little and watched them in the mirror and it looked like they were coming closer. I knew that I had not passed another car and it did not seem like a car would be coming down that dark road backwards. I stopped and stuck my head out the window and looked back and there was nothing there. Then I looked in the mirror again and there they were and they were right behind my car. I gunned it and got the hell out of there. What I saw wasn’t a car.
Just as ominous is the appropriately named “Demon’s Road” in Huntsville, Texas, which is already spooky enough, as it meanders through groves of twisted trees and darkened woods and ends up at the desolate Martha’s Chapel Cemetery. The real name is Bowden Road, but it has earned its nickname in the decidedly frightening phenomena that have been reported from here, such as shadow people, a ghostly child on a tricycle, a hulking faceless beast, a strange hooded figure, and arms reaching out from graves. There are many spirits said to lurk along the murky stretches of this road and in the cemetery, but one of the creepiest is a ghost light that seems to be quite malicious indeed.
Motorists venturing down the Demon’s Road have often reported mysterious red lights hovering about in the dark, the number of which seems to depend on how many people are in the vehicle at the time. These spook lights will supposedly aggressively pursue cars, and spookiest of all, will leave unexplained handprints on the outside. Indeed these lights have plagued many who have travelled down the road, often leaving those handprints and always hostile, sometimes even clawing or grabbing at cars to leave scratches and dents behind. What could this diabolical force be and why does it want to attack vehicles? Who knows?
Another case in Texas of an aggressive ghost light is that said to roam a road in Hardin County leading from Bragg to Saratoga, which actually at one point was a part of the Santa Fe Railroad back in the early 1900s before being paved over to be turned into a road. In an area called Big Thicket there have long been reports of a multicolored spook light hovering about at night along the road and in the surrounding wilderness, with many of them pointing at the light being quite evil.
Even from beginning the reports of the Big Thicket ghost light, also called the Saratoga ghost light, were far from friendly. Hunters reported being chased by the lights and it was not uncommon to here of them rushing amongst horses to send the animals into a panicked frenzy, to the point that on at least one occasion a horse drawn wagon was forced to go crashing into a ditch because of the lights. At the time the lights became a pretty widespread rumor, attracting all sorts of curiosity seekers, and author F.E. Abernethy would explain of the phenomenon in his book Tales from the Big Thicket thus:
Light-seers poured onto the road by the hundreds. People of all ages and intellects came to see and test their belief in the supernatural. They shot at it, they chased it, and they tested it with litmus paper and geiger counters. A preacher harangued the road’s multitudes from the top of his car, making the Light as an ill omen of the world’s impending doom. There were some nights the light didn’t show at all, but for the most part it was there to inspire stories that could be passed on, to change and grow at the will and imagination of the story teller.
The Big Thicket Ghost Light road
In later years the light did not stop its antics in the slightest bit, with reports of it chasing people or even attacking them common, such as cases in which the light stopped car engines, burned people’s hands, or even violently knocked them down. There have been reports of cars being dinged, dented, or smashed by the ghost light, and it is generally not something one wants to encounter while driving down the already eerie rural road. As usual there have been many attempts to rationally explain the Big Thicket Light, such as that it is some sort of illusion, swamp gas, or merely headlights, and there have been a fair number of more paranormal explanations as well, including that it is the spirit of a hunter or Civil War soldier, or even that it is a curse placed over a lost Spanish treasure. Whatever the case may be, the stories of the evil ghost light of Saratoga persist.
Texas seems to be a haven for such spook lights, because there is another road in this state that has its own scary stories of such entities. In the area of the Mitchell Flat, east of Marfa, Texas, there have long been reports of mystery lights floating out over the desert landscape since at least the 1800s. The phenomena are usually described as dancing orbs of light that zip and zoom low to the ground over the parched desert scrub, and they have collectively been coined the “Marfa Lights.” While the phenomenon is puzzling but usually harmless, there have been some reports that show these lights can be rather frightening on occasion.
In one report from Weird Texas, one man named Tim Stevens gave an account of a very bizarre experience witnesses by a friend of his father’s named Roy while traveling down Route 90 in the 1970s. According to the report, Roy had been driving for hours out from San Antonio after sunset and just before dark, and there had been no other cars out on this remote stretch of the highway that evening. Suddenly, he noticed what he took to be headlights in his rear view mirror. For some time the lights remained a comfortable distance away, but at some point the lights quickly closed the distance to follow right behind him. The report explained the follwing sequence of events:
My dad said that Roy had been driving with the lights a comfortable distance behind him for several minutes when the vehicle sped and up and approached his truck rapidly. For a few seconds, he honestly thought he was about to be rear-ended. Before an impact occurred, however, the lights stopped a few feet short of hitting his truck. At 60 MPH, in the middle of an otherwise deserted highway, it probably wasn’t too much to ask for the courtesy of a little breathing room. So Roy tapped the brakes. The driver of the vehicle behind him maintained his distance. Roy again tapped his brakes––no response. Finally, very annoyed, Roy jammed hard on his brakes for a fraction of a second. To his amazement, the vehicle behind him stayed the exact distance from his rear bumper as it had been.
Roy decided to try a different approach. He said he floored the gas pedal making his small truck shudder and lurch ahead. The speed crept up to 80 MPH. The lights behind him reacted in perfect unison, staying several feet behind his truck, as it approached speeds Roy was sure he’d never pushed it to before. At nearly 100 MPH, the truck was beginning to vibrate badly, but the lights did not waiver.
Enough was enough. Roy eased off the gas and let the truck coast down to a sane speed, and then he stood on the brakes. The tires screeched and smoked, and the truck pitched and slid slightly to the side––but the whole time, Roy watched the lights in the mirror. They stayed in exactly the same spot until the truck came to a stop. Roy then saw something completely unexpected––the lights shot out, off the road to the right, and fired across the desert like missiles. He craned his neck around to try and follow them visually, impressed by the driver’s driving on what was sure to be very rough road. He smiled and was about to drive on when a thought occurred to him.
He frowned, and, making sure that he wasn’t about to be run over by a big rig or other traffic, put his truck in reverse and slowly backed up maybe a couple of hundred feet. He checked the barbed wire fence line for a road, a gate, or other break of some kind where his pursuer might have slipped through––but there was none. Roy said he was pretty spooked, alright. Off in the distance he could see lights moved swiftly across the horizon.
Whatever this was, whether it was connected to the Marfa Lights or not, it certainly seems hard to explain away as a trick of light or headlight reflections from the distance. Ghost lights have been a persistent phenomenon within the world of the weird, and there have been countless theories to try and explain them. Yet, none seem to touch on those lights that seem to reach out from the merely mysterious to lash out at those who encounter them. Is there some explanation for this or is this hoaxes and tall tales? If it is indeed real, then why do these particular spook lights cling to these locations, and why do they seem so hostile and threatening? It seems to be beyond our ability to comprehend at this point, and these lights may flit about the periphery of our understanding prowling their haunting grounds without ever being satisfactorily explained.
Which is more shocking: the fact that Jupiter has at least 12 more moons than once thought or the fact that they were discovered by real astronomers who were looking for the mythical Planet Nine? Planetary scientists announced that the discovery of the tiny and somewhat erratic moons brings Jupiter’s total to 79, but are they just bragging to cover up the time they spent searching for an allegedly apocalyptic yet unproven giant planet?
12 new moons discovered around Jupiter
“Jupiter just happened to be in the sky near the search fields where we were looking for extremely distant Solar System objects, so we were serendipitously able to look for new moons around Jupiter while at the same time looking for planets at the fringes of our Solar System.”
In a press release by The Carnegie Institution for Science, part of the Carnegie Institution of Washington, astronomer Scott S. Sheppard admitted publicly that he and his team were looking for Planet Nine or Planet X in 2017 when Jupiter passed into the field of vision of their telescopes and they spotted the 12 tiny new moons. “Tiny” is an overstatement – most the moons range from just one to three miles in diameter. It required waiting a year for them to appear a few more times before the team was confident enough to announce the find.
Jupiter and its four biggest moons
12 new moons discovered around Jupiter
Nine of the newly discovered moons are in three groups making distant retrograde orbits (opposite Jupiter’s rotation) and the researchers speculate they may be what’s left of three larger moons that suffered collisions with each other, other moons, asteroids or comets. Two more moons are closer to Jupiter and follow its spin. Their matching orbits and tilts indicate they were probably once a single moon.
Then there’s the tiny eccentric satellite.
“Our other discovery is a real oddball and has an orbit like no other known Jovian moon. It’s also likely Jupiter’s smallest known moon, being less than one kilometer in diameter. This is an unstable situation.”
According to Sheppard, this moon’s orbit is prograde despite being far enough from Jupiter that it should be retrograde or at least off-kilter due to collisions. The abundance of these tiny moons suggests that they formed after the solar system’s planetary creation had settled down, allowing them to survive rather than be knocked down by Jupiter’s formational gas and dust.
While Sheppard seemed excited about the discovery of this odd and minute moon, its chosen moniker suggests otherwise. The astronomers named it Valetudo after the Roman goddess of health and hygiene. Really? There’s a goddess of hygiene? How far down the line of succession is she?
Valetudo
And what about Planet Nine? The announcement seems to overplay the discovery of moons around a planet that already had five dozen of them and doesn’t mention much about the Planet Nine search. Is it being phased out due to lack of success? Did the discovery of Valetudo and her friends save some jobs?
Is there a god of hygiene or did the Romans figure men wouldn’t listen to one anyways?
A giant black sarcophagus the likes of which have never been seen before has been found deep within the ground in Egypt, and a whole lot of scientists want to open it – despite having neither one earthly nor one unearthly idea what might lie waiting possibly maliciously inside. Say it with me now: “What! Could! Go! Wrong?” [cue applause and intro music]
Today’s episode of What The Hell Are They Thinking? comes to you straight from the ancient city of Alexandria in Egypt, one of the cradles of Western civilization as we know it. Earlier this month, construction crews there unearthed a true archaeological mystery the likes of which can only be found in Egypt. A massive alabaster head was found in the ground, the identity of which still remains a mystery. Even stranger (and scarier), a massive black sarcophagus was discovered nearby, measuring two meters by three meters, weighing over 30 metric tons, and carved entirely from black marble. Sounds like the perfect way to entomb an immortal evil wizard if you ask me.
How would you feel if some science nerds a few thousand years from now cracked open your coffin to look at your embarrassingly shriveled remains? How are they supposed to know you’re a grower and not a shower?
But they didn’t ask me. Instead, a team of archaeologists and scientists from Egypt’s money hungry Ministry of Antiquities will crack the menacing-looking thing open despite the entirety of the internet knowing that it’s a terrible idea. “We are hoping this tomb may belong to one of the high dignitaries of the period,” Ayman Ashmawy, the head of Egypt’s Ministry of Antiquities said in a statement, his pupils turning into dollar signs as he eyes the sarcophagus and licks his lips. “The alabaster head is likely that of a nobleman in Alexandria. When we open the sarcophagus, we hope to find objects inside that are intact, which will help us to identify this person and their position.”
Let’s take a step back for a second, though: why would you take the time and resources to bury something underneath a 15-ton slab of black marble unless you really, really want it to stay there? But no, fetch the crowbars and let’s get crackin’ boys! There’s museums to stock and tours to plan!
“Why did you release me!? I wasn’t finished with my cleanse yet!”
While in all likelihood the tomb contains nothing more than the stinking remains of some poor inbred aristocrat and all of his junk, there does in fact seem to be a precedent for a real-life pharaoh’s curse – although it seems the “curse” is more like a lifetime of disappointment and waning fame living in the shadow of your greatest discovery than a persistent haunting from a vengeful ancient ghost. But who knows? Maybe vengeful ancient ghosts work in mysterious ways. Maybe evil wizards don’t like being buried for 2,000 years in a musty black marble box. Maybe some things are better left in the ground where one of the most advanced civilizations in human history clearly wanted it to stay.
I’ll be in the bunker tonight, honey; no dinner for me. I’ve got talismans to enchant and salt circles to pour.
Diamonds are not rare at all on Earth- Representational imagePixabay
Diamonds are famously known to be both rare and "forever". Both of those supposedly well-known facts are, as it turns out, not true at all.
New research by a team from MIT, Harvard, and Berkeley has found that there is a lot more diamond in the planet than once believed. A quadrillion tonnes, or about a 1,000 trillion tonnes of diamond is buried below the Earth, but it is out of reach to humans. At about 120 to 150 km below the surface, it is out of reach of even the best drills available right now.
That means there are more diamonds than gold on the planet. According to a BBC report, there is only 2.5 million tonnes of the shiny metal in the world.
"This shows that diamond is not perhaps this exotic mineral, but on the [geological] scale of things, it's relatively common," said Ulrich Faul, of MIT's Department of Earth, Atmospheric, and Planetary Sciences.
"We can't get at them, but still, there is much more diamond there than we have ever thought before."
Astronomers Spot ‘Celestial Diamond Ring’ Nebula - Diamonds are surprisingly common in outer space

This massive stash of diamonds are stored in rock formations called cratons. Cratons form as a result of tectonic plate movement. Similar to the way mountains happen as a result of tectonic movement and are pushed up, cratons are pushed down. They can be likened to inverted mountains and can go as deep as 200 miles, says MIT. At the very bottom of these cratons lie the diamond "roots". The study found that diamonds likely make up about 1 to 2 percent of croton roots.
As to how this find was made, the tech is similar to what is used to detect and measure seismic activity, or earthquakes. Seismic data can also be used to effectively see inside Earth, similar to an ultrasound scan.
Sound travels faster in more dense material than light materials, so its speeds vary according to the composition, temperature, and density of rocks below the surface. By comparing the way sound travels and bounces back, scientists can accurately find what rock lies beneath the surface and at what depth they lie.
The study was published by the American Geophysical Union.
Jupiter has been found to have a dozen more moons orbiting it and they have been idenrified for the first time. Of the 12, 11 moons are "normal" outer moons, and one "oddball" moon. That makes Jupiter the planet with the highest number of moons with a grand total of 79 natural satellites—the highest of any planet in the solar system.
The team of astronomers were led by Scott S. Sheppard, of Carnegie. The moons were first spotted in the spring of 2017, says a release put out by the researchers. This discovery was made while on the lookout for distant solar system objects far beyond Pluto. They were looking for the mysterious Planet 9, which is believed to be a massive object that is actually affecting Pluto's orbit and even possibly firing comets at Earth.
12 new moons have been seen and identified for the first time ever

A few years back in 2014, this same team found an object with the most-distant orbit in the solar system. They were also the first to realise that there just might be a massive planet out there in the outer reaches of the solar system. This "Planet 9" is also sometimes called Planet X.
"Jupiter just happened to be in the sky near the search fields where we were looking for extremely distant solar system objects," said Sheppard.
So we were serendipitously able to look for new moons around Jupiter while at the same time looking for planets at the fringes of our solar system," he added.
Using the team's observations, Gareth Williams at the International Astronomical Union's Minor Planet Center was able to measure out the orbits for these newly found moons each about one to three kilometres in size.
The newly discovered Moons include one oddball moon that could collide with the outer Moons of Jupiter
Carnegie Institution for Science
As to why the announcement comes so long after it was first observed since the spring of 2017, Williams said that, "It takes several observations to confirm an object actually orbits around Jupiter."
"So, the whole process took a year."
Nine of the 12 newly discovered moons are reported to be a part of Jupiter's distant outer swarm of moons that orbit it in the retrograde—opposite direction of the planet's spin. These distant retrograde moons are now grouped into at least groups that are thought to be the remnants of three once-larger parent bodies that broke apart because of collisions with asteroids, comets, and other moons near Jupiter. The retrograde moons take nearly two years to completely orbit Jupiter.
Of the remaining 3, 2 moons are part of a close, inner group that orbit in Jupiter's prograde--same direction as planet rotation. They also have similar orbital distances from the gas giant and their angles of inclination around Jupiter point out them also once being part of a much larger boody that has since broken down. These two moons, being a lot closer to the planet take less than a year to travel around Jupiter, say the researchers.
"Our other discovery is a real oddball and has an orbit like no other known Jovian moon," Sheppard explained. "It's also likely Jupiter's smallest known moon, being less than one kilometer in diameter."
The one "oddball" moon lies between the two groups of moons and its orbit is more inclined than the prograde group. This one takes about one and a half years to orbit Jupiter, say the researchers. This moon also has a prograde orbit, but its path crosses the outer retrograde moons. Chances of the oddball moon crashing into the outer retrograde moons moving in the opposite direction are very real, say the astronomers, who have proposed the oddball be named "Valetudo" after the Roman god Jupiter's great-granddaughter, the goddess of health and hygiene.
Sheppard called this situation unstable and explained that, "Head-on collisions would quickly break apart and grind the objects down to dust."
Nick Pope, a British media commentator who worked with the British Government's Ministry of Defence (MoD) from 1985 to 2006 has claimed that unidentified flying objects (UFO) are real. In an exclusive story written for the Sun, Pope revealed that most of the UFO sightings could be explained, but around five percent remain mysterious.
UFOs are real
As per Nick Pope, the cases which perplexed his MoD team during the investigation were the near misses between UFOs and commercial aircraft. The former MoD insider argued that many pilots have reported mysterious UFO encounters which still remain unanswered.
"The bottom line was that we knew UFOs were real, but we didn't know what they were. What was much more fun was the other weird stuff that came our way simply because there was nowhere else in government to send it: crop circles, claims that people had been abducted by aliens, ghost sightings and people who claimed to be psychic and volunteered their services to British intelligence," wrote Nick Pope on the Sun.
Nick Pope also made it clear that Russians and Chinese had conducted tremendous probe to unravel the mystery behind UFO sightings. As per Pope, Russians had also researched and investigated about parapsychology, telekinesis, and various other psychic phenomena.
US government's clever move
The former Directorate of Defence Security also talked about Pentagon's secret UFO search program 'Advanced Aerospace Threat Identification Program (AATIP)'. He wrote that the US government did a very clever move by not mentioning the word UFO in the name of the investigation program.
"We still don't know much about AATIP, and it may take Congressional hearings to resolve the issue. Either way, if anyone was laughing about UFOs before, they're not laughing now," added Pope.
He also revealed that the UFOs spotted in the gun camera footage of the Royal Air Force were very similar to that of the flying objects featured in the declassified videos released by Pentagon.
