Alien 'doorway' discovered on Mercury's surface by conspiracy theorists - but where does it lead to?
Alien hunter Tyler Glockner had his own theories about what the door found on satellite imagery might be - and whether it is still in use
Conspiracy theorists have found what they believe to be an 'alien doorway' on the surface of the planet Mercury.
The rectangular shaped object was first spotted on satellite imagery by Scott C. Waring of UFO Sightings Daily, who claimed it showed proof of an 'entrance' on the planet .
But the video footage was uploaded by alien hunter Tyler Glockner from Secure Team 10, who gave his own theory.
Talking over the clip, Tyler says: "Mercury has been rarely spoken about by the space agencies.
"There has been a question of whether there is a reason why planets like Mercury are rarely spoken about and that maybe that's because they don't want anyone's attention focusing on [them]."
Secure Team
The bizarre alien 'doorway' was spotted on planet Mercury
Tyler points out that the rectangular shape appears to be out on its own with no similar shapes nearby.
But as he further examines the image, he offers an alternative theory to Waring's doorway idea.
"It became clear to me that this is not an entrance at all. In fact, it's something much more magnificent.
"This big, black rectangle? This is a shadow. So then you ask, where's the shadow coming from, and what is casting such a large, long shadow?
Secure Team
Tyler claims Mercury is barely ever talked about and could have secrets
"And that my friends, is this large rectangular object, monolith-looking structure towering up above the surface."
The footage was uploaded to the Secure Team 10 YouTube channel on November 8 and has been viewed more than 238,000 times.
Viewers were divided over the video, with one writing: "It looks like an electrical discharge from something."
But another simply said: "That's a shadow on Mercury, not a doorway."
The incident has divided investigators, with explanations ranging from space debris to even an alien spaceship disguised as a meteor
A glowing green ball of light appeared in the sky in Japan this week, baffling expertsas to what it actually is.
The orb was captured hovering over Niigata, northern Japan, in the early hours of Monday morning.
This footage shows the green light shooting diagonally across the sky as sparks fly from the tail of it.
The incident has caught the attention of scientists, who have yet to determine what the UFO is.

It has yet to be identified as a meteor or a UFO
One astronomer told NBC News that it was probably a bright meteor, known as a fireball.
But they did mention that it could be a piece of space debris that burnt up as it entered the atmosphere, such as a satellite.
It has divided opinion, as one UFO investigator claims it was actually aliens entering Earth's space.
Scott C Waring of UFO Sightings Daily claims the object is an alien space craft trying to disguise itself asa meteor.

The light ball baffled thousands of people across Japan
He said that the glowing light was an alien, claiming that meteors don't glow green and that the curve of its flight was too straight to be a fireball.
The actual origins of the green ball of light haven't yet been identified.
The fireball rapidly lost height as it 'fell' to earth

Residents were baffled by the huge fireball
According to an expert in the field, the two dark-coloured ships are shown in stark contrast against a bright white moon, seemingly flying side by side.
He wrote on his UFO Sightings Daily blog : “His editing software allows us to see its actual shape…a perfect saucer…two of them.
“There is no way these disks are satellites,” he adds, claiming that such manmade technology would not fly so close.
He added: “These are actual UFOs, flying in military style, because they are flying with a wingman to keep each other out of possible trouble."
Sheila Butt/Postmedia NewsResidents of Igloolik, Nunavut have thrown around many possible explanations for the strange sounds appearing to come from the sea bottom.
The theories range from UFOs operating under the ice to the release of methane gas to Russian or U.S. submarines lurking in Canadian waters.
But one possible explanation for the mysterious sounds seemingly coming from the ocean floor in Canada’s Arctic may be rather straightforward, suggests a U.S. scientist working on a project that generates low-frequency sound in the far North. It could be ice rubbing together.
Last week, acting on a request from the government of Nunavut, the Canadian military sent a CP-140 Aurora aircraft to conduct surveillance of Fury and Hecla Strait, northwest of the hamlet of Igloolik. Hunters in the area have reported hearing noises ranging from hums to pings to beeps. They say the noises are driving animals away.
“The sound that has been heard in the area seems to be emitted from the seabed and underwater,” Paul Quassa, a member of Nunavut’s legislative assembly, told lawmakers on Oct. 25.
According to Department of National Defence spokesman Dan Le Bouthillier, the Aurora’s crew conducted “various multi-sensor searches in the area, including an acoustic search for 1.5 hours, without detecting any acoustic anomalies. The crew did not detect any surface or subsurface contacts.”
The Aurora crew did observe two pods of whales and six walruses in the area of interest, Le Bouthillier added.
Residents have speculated about various theories for the sounds, including that a mining company may be conducting sonar surveys or that environmentalists may be using some kind of device to scare away animals so they can’t be hunted. Others have suggested the release of methane gases from the ocean floor or clandestine visits by Russian or U.S. submarines.
Google MapsFury and Hecla Strait
One of the more prominent theories focused on the claim the sounds were being emitted by a science project in the Arctic funded by the Office of Naval Research in the U.S.
That project, called the Canada Basin Acoustic Propagation Experiment, or CANAPE, uses low-frequency sound to determine how the ongoing changes in sea ice affect acoustics. The project could produce data for use in tracking submarines in the far North.
But Peter Worcester of the Scripps Institution of Oceanography at the University of California said the sounds being generated by CANAPE are very low and too far away to be heard in the Fury and Hecla Strait.
“The signals transmitted for CANAPE are only expected to be above the background ocean noise level out to a range of at most a few hundred kilometres, which is much less than the distance to Fury and Hecla Strait,” said Worcester, who heads the project.
“Even if the signals were louder, any underwater sound generated north of Alaska would be blocked from reaching Fury and Hecla Strait by the many islands in the Canadian Archipelago.”
Worcester said he didn’t know what would cause the mystery sounds and is loath to speculate since he hasn’t heard them himself. But he noted much of the acoustic noise in the Arctic is caused by ice rubbing together, cracking, and moving. Early Arctic explorers called the noises the “Devil’s Symphony” with descriptions ranging from buzzing to wheezing and loud bangs.
“You can even get things where the ice hums, where you get sounds that resonate almost like an organ pipe,” Worcester explained. “There was a paper written about the notion there are various melodies associated with the sounds generated by sea ice.”
A spokesman with the DND said the department considers the issue of the mystery noises closed and there are no plans to send more aircraft to investigate.

De supermaan komt eraan: bewonder hem komende maandag
De supermaan komt eraan: bewonder hem komende maandag
Caroline Kraaijvanger
Het is maandag volle maan én de afstand tussen de aarde en de maan is minimaal. Het resultaat: een supermaan!
Komende maandag – 14 november – is het volle maan én staat de maan relatief dicht bij de aarde. De afstand tussen de twee hemellichamen bedraagt een slordige 356520 kilometer. En omdat de maan dichter bij de aarde staat, lijkt deze veel groter (tot wel veertien procent) en helderder (tot wel dertig procent).
Ovaalvormige baan Maar hoe kan de maan nu het ene moment dichter bij de aarde in de buurt staan dan op het andere moment? Dat komt doordat de maan niet in een perfect ronde baan rond de aarde draait: de maan heeft en licht ovaalvormige baan. Op het moment dat de afstand tussen de maan en de aarde het kleinst is, kan de maan tot wel veertien procent dichter bij de aarde in de buurt staan dan wanneer de afstand tussen de aarde en maan het grootst is.
Twee van drie De supermaan van komende maandag is de tweede van drie supermanen (16 oktober, 14 november en 14 december) die ons in 2016 gegund zijn. Officieel is de supermaan van komende maandag de beste. NASA bestempelt deze als een ‘extra-supermaan’. Op 14 oktober en december is de afstand tussen de maan en de aarde het kleinst op dezelfde dag als volle maan. Op 14 november zit het moment van perigeum (het moment waarop de afstand tussen de aarde en maan het kleinst is) dichter op het moment waarop het volle maan wordt. Vanuit Nederland zijn de verschillen tussen de drie supermanen – met het oog op het exacte tijdstip waarop het volle maan wordt – echter nauwelijks waarneembaar.
Wie de supermaan komende maandag wil zien, hoeft daar geen gebroken nachten voor over te hebben. Je kunt de maan direct na zonsondergang al bewonderen. Mocht je agenda al volzitten of bewolking roet in het eten gooien, dan kun je dus uitkijken naar 14 december.
Ajoint investigation between scientists from the Center for SETI Research at the SETI Institute and METI International resulted in the discovery of exactly zero radio transmissions emanating from KIC 8462852, aka Tabby’s Star, aka that “alien megastructures” star everyone freaked out about late last year. According tonew findings published in The Astrophysical Journal Letters, we still haven’t found signs of extraterrestrial intelligence. Our cold streak continues.
In case you don’t remember, there was a big hooplah last fall when Jason Wright, an astronomer at Penn State University, dropped a small suggestion that strange stellar light patterns glowing from Tabby’s Star, nearly 1,500 light-years away from Earth, were caused by “alien megastructures,” a catchall phrase for materials artificially placed in orbit. Since then, study after study has basically put that hypothesis to rest, with more reasonable ideas like a family of weird cometsgarnering more and more support based on new data.
But science is about making confirmations, so the dutiful scientists at the SETI Institute and METI international came together and used the Boquete Optical SETI Observatory in Panama to determine whether or not the strange dimming patterns were caused by intelligent extraterrestrials, as well as use the Allen Telescope Array in California to measure whether the star system was spewing out any radio signals indicative of advanced technology.
“We were looking to see if there are intentional laser signals being beamed at us,” says METI International research and study coauthor Douglas Vakoch. He tells Inverse he and his colleagues were looking for the kinds of signs of technology that us humans on Earth might be capable of building and using to broadcast our presence to the rest of the universe.
Unfortunately, they did not find any radio signals, and the optical signals found were less than encouraging. No optical signal of a particular period pattern was measured, and the power of the light pulsing from Tabby’s Star didn’t seem characteristic of a laser signal. “If there is a large laser facility kicking out signals of 5 mega-joules or stronger, we would have been able to detect those,” says Vakoch. “We didn’t.”
Vakoch emphasizes that the results don’t totally discount alien life living in the star system. He and his team were using Boquete during Panama’s rainy season — “the worst possible time,” he says. He acknowledges that the results “don’t say for sure there aren’t extraterrestrials out there.” It’s always possible E.T. is sending weaker signals out or exhibiting patterns stretching across a larger timeframe.
“But we can say that within the scenario where we could have possibly gotten a signal, we didn’t get one,” says Vakoch.
Disheartening, sure, but there’s a strong silver lining to the new findings. While SETI research around the world centers in large part around the measure of radio signals, the new investigation allowed the scientists to flex their optics muscles and get practice at looking for signs of E.T. across other frequencies as well. “If we get a signal, there may be different sources of information at different frequencies, so we need to be ready to jump on that,” said Vakoch.
Moreover, the study demonstrated the feasibility of using even a modest-sized optical telescope to conduct SETI observations. This runs counter to the whole “bigger is better” mentality that permeates space science, and Vakoch thinks the new methodological approaches he and his colleagues outline in their paper illustrate a new model for doing SETI research that is more efficient and sustainable. He says a major goal of METI International, after all, is to answer “how do we sustain the search going forward” as funding for these types of projects drop or become thinned out over more and more initiatives.
“We still don’t have a natural explanation for what is going on” with Tabby’s Star, says Vakoch. And he doesn’t find that particularly discouraging. “This is the type of ambiguity we can expect if we really got a signal from E.T. It will be a slow unfolding and grappling of the data. So we continue to search for answers.”
Protoplanetary disks are celestial bodies found around young stars, which will eventually be sculpted into round spherical as we know them. They’re the subjects of the European Southern Observatory’s Spectro-Polarimetric High-contrast Exoplanet REsearch instrument, which has been somewhat forcibly maneuvered into the acronym SPHERE. On Wednesday, the ESO released new images and data, captured by three teams of astronomers using SPHERE, of what those young solar systems look like in action.
SPHERE’s cutting-edge precision is able to deliver the kind of detail we need in order to better understand the evolutionary processes of these nascent stars and planets. It has adaptive optics that compensate for visual distortion and a coronagraph that keeps the light from the central star from blowing out the rest of the image. It can also isolate light coming from the star and separate it from the features forming in the disk to make for a more accurate reading.
SPHERE’s first observation, or “first light,” was in June 2014. It uses direct imaging— basically, taking highly detailed pictures of the exoplanets scientists have their eye on. Getting usable direct imaging data from protoplanetary disks is no small feat (though it’s not easy to capture regular planets either).
Concentric rings on the disk around the star RX J1615.
Protoplanetary disks aren’t actually solid — the term refers to expansive clouds of stellar gas and dust that compact into planets over time. But the specifics of that process, including how some planets end up with rings or arms, still aren’t known to us. A SPHERE team hailing from the Netherlands obtained images of rings already forming in an especially young disk — a rare and valuable set of data. Observation of a second symmetrical system soon followed, which is important because prior to this we were mostly finding disks with asymmetrical features — this might mean there are more of the former out there than we thought.
Arm-like spiral structures on the disk around star HD 135344B.
The teams also observed cool phenomena like a “large central cavity and two prominent spiral arm-like structures,” which should eventually develop into something resembling Jupiter. They were also lucky enough to capture images of four separate dark streaks — shadows of young planetary material — one of which changed in shape between observations, meaning SPHERE is getting the data of it dynamically evolving in real time. The takeaway from all of this is basically that protoplanetary spheres are full of surprises — tantalizing, immensely rich fields of study that we now have the technology to better explore.

What's in a name? When it comes to catchy monikers, most galaxies come up short.
But perhaps that isn't so surprising. With an estimated 100 billion to 200 billion galaxies in the known universe, it's no wonder that the majority of galaxies that have been identified thus far go by a catalog number: M51, GN-z11, and IOK-1, for example. Those arrangements of numbers and letters are loaded with meaning for astronomers, but they don't exactly inspire the imagination.
However, a handful of galaxies have fared a little better in the naming department — usually the ones that are distinctively shaped, extremely close by and easy to observe, or just exceptionally photogenic. Here's a look at some of these galaxies with standout names.

1. Milky Way Galaxy
Our home galaxy, the Milky Way, measures 100,000 light-years in diameter, and is thought to contain at least 100 billion stars and possibly as many as 400 billion or more. It is a barred spiral galaxy, with a central bar structure running across its core.
Though the Milky Way was long thought to have only two spiral arms, a 12-year study published in the journal Monthly Notices of the Royal Astronomical Society in 2013 confirmed that the galaxy has four major arms. Our sun and solar system are located on a minor structure known as the Orion Arm, about 26,000 light-years from the Milky Way's center.
Thousands of years ago, the Milky Way's bright sprawl of stars, dust and gas stretching across the night sky inspired the ancient Greeks to lend it a milky name, though historians are uncertain as to when it was first referred to as the Milky Way, according to Matthew Stanley, a professor of the history of science at the Gallatin School of Individualized Study at New York University.

2. Tadpole Galaxy
A close encounter with another galaxy disrupted the spiral galaxy Arp 188, commonly known as the Tadpole Galaxy. Like its aquatic eponym, the Tadpole has an oval "head" — the main part of the spiral — and a long, trailing "tail."
The sweeping appendage measures about 280,000 light-years in length and is studded with enormous and brilliant star clusters. It likely formed when another galaxy approached too close to the Tadpole and was swung around behind it by gravitational forces. That same attraction probably teased out the ribbon of stars and gas that now trails behind the Tadpole, according to a NASA description.

3. Eye Galaxy
Messier 64 (M64) has a somewhat sinister common name: the Black Eye or Evil Eye Galaxy, inspired by the dark band of dust surrounding its bright core. This shadowy band likely formed after a collision with another galaxy.
In the 1990s, scientists discovered that gas in the Black Eye's outer regions was rotating counterclockwise — the opposite direction from the gas and stars closer to the center. Astronomers suspected that this unusual region is the last remnant of a smaller galaxy that collided with the Black Eye over a billion years ago, and was gradually absorbed.
The Black Eye is located in the constellation Coma Berenices, approximately 17 million light-years from Earth, and was catalogued by French astronomer Charles Messier in the 18th century.

4. Sombrero Galaxy
The Sombrero is a spiral galaxy, and its unusual hat-like shape is suggested by our perspective on its position in space, viewed edge-on from Earth. This creates the illusion of a hat's "brim" — the outermost ring of stars — and a "crown" where the luminous core bulges at the center, circled by darker lanes of dust.
Also known as Messier 104 (M104), the Sombrero is located about 28 million light-years from Earth and measures 50,000 light-years across. It is one of the most massive objects in the Virgo cluster — as big as 800 billion suns, according to the Hubble Space Telescope website.

5. Whirlpool Galaxy
Like our own Milky Way, the Whirlpool (Messier 51, or M51) is a spiral galaxy — the most common galaxy type, representing about 77 percent of all galaxies in the universe — with multiple arms curving outward and wrapping around a bright center. Its yellowish core is home to older stars, while younger and brighter stars are visible along its arms.
The arms of the Whirlpool — as in all spiral galaxies — are stellar nurseries, where infant stars are born. At only 25 million light-years from Earth and measuring 60,000 light-years across, the Whirlpool is highly visible to astronomers and has been called one of "astronomy's galactic darlings" by the Space Telescope Science Institute (STScI).
Stellar deaths have been detected in the Whirlpool, as well. Observers reported three supernovas — a star's explosive demise — occurring in the Whirlpool during the past 17 years: in 1994, 2005 and 2011.

6. Cigar Galaxy
Located in the Ursa Major constellation about 13 million light-years from Earth, the Cigar Galaxy was named for the long, elliptical shape of its disk, which is how it appears relative to our sight line.
Also called Messier 82 (M82), the Cigar is known as a starburst galaxy — one with an exceptionally high star birth rate. In its central regions, stars are produced 10 times faster than in the Milky Way Galaxy, according to the European Space Agency (ESA).
This six-image composite mosaic — the sharpest wide-angle view ever obtained of the Cigar Galaxy — was assembled from images taken by the NASA/ESA Hubble Space Telescope, in March 2006.

7. Cartwheel Galaxy
Resembling an oversize wagon wheel, the Cartwheel Galaxy is estimated to measure 150,000 light-years across. It has a bright center with wispy "spokes" of dust and gas radiating outward to a surrounding ring of stars, which is about 1.5 times the size of the Milky Way, according to the Hubble Space Telescope website.
The Cartwheel's unusual shape was caused by a dramatic, head-on cosmic collision millions of years ago, according to a description on the Chandra X-Ray Observatory website. It was originally a large spiral galaxy, but a smaller galaxy perforated its center, disrupting stars much like a stone dropped in water causes outward-spreading ripples.
It is located 500 million light years from Earth, in the Sculptor constellation.

8. Sunflower Galaxy
Galaxy Messier 63 (M63), also known as the Sunflower Galaxy, was the 63rd entry in French astronomer Charles Messier's catalog of celestial objects, published in 1781, and was given its flowery name for the tight spiraling of its many arms, which was thought to be reminiscent of the pattern at a sunflower's center.
The Sunflower is about 27 million light-years from Earth in the constellation Canes Venatici — "The Hunting Dogs" — and is part of the M51 Group, a collection of galaxies that also appears in Messier's catalog and is named for Galaxy M51, the Whirlpool Galaxy.
The brilliant glow that illuminates the Sunflower's spirals is generated by newly formed blue-white giant stars, according to the Hubble Space Telescope website.
Neanderthals and modern humans interbred long ago, but evolution has purged many of our caveman relative's genes from modern human genomes, a new study finds.
Neanderthals were the closest extinct relatives of modern humans. Previous research suggested that modern humans migrating out of Africa encountered and interbred with Neanderthals tens of thousands of years ago.
"We know that the ancestors of modern Europeans and Asians mated with Neanderthals, and as a result, the modern-day descendants of those people have some small amount of Neanderthal DNA in their genomes," said study lead author Ivan Juric, an evolutionary biologist at the University of California, Davis. [In Photos: Neanderthal Burials Uncovered]
However, nowadays, Neanderthal genetic material makes up only about 1.5 to 2.1 percent of the genomes of people outside Africa, according to the draft sequence of the Neanderthal genome published in 2010. That means some of this genetic material was lost over time. To better understand why this evolutionary purge occurred, Juric and his colleagues examined where Neanderthal DNA was found in the modern human genome.
If offspring of modern humans and Neanderthals had Neanderthal DNA segments that possessed some so-called deleterious alleles — that is, harmful genetic variants — "then they'd be less likely to have kids, and so less likely to pass on those Neanderthal segments to future generations," Juric told Live Science.
In this way, the evolutionary mechanism of natural selection ensures that "over time, Neanderthal segments containing deleterious alleles get removed from populations faster than Neanderthal segments not containing deleterious variants," Juric said.
Previous research found that there is less Neanderthal DNA in regions close to genes than in the relatively inactive regions between genes. This suggests that natural selection weeded out Neanderthal variants of those genes, Juric said.
Juric and his colleagues developed a computer model that simulated the effects of natural selection on the distance between segments of Neanderthal DNA and modern human genes. Given the amount of time that has passed between interbreeding between Neanderthals and modern humans and the amounts and locations of Neanderthal DNA now found in the modern human genome, their findings suggest that many Neanderthal gene variants that entered the modern human genome after Neanderthals and modern humans interbred were "weakly deleterious" — that is, "they are being slowly removed by natural selection," Juric said.
The researchers suggested that many mildly negative gene variants, or alleles, were able to persist in Neanderthals because Neanderthals had much smaller populations than modern humans. However, when these gene variants made their way into modern humans, modern humans' larger populations — and thus bigger gene pools — were better at winnowing out these deleterious alleles.
"I find it fascinating to think that if the Neanderthals had reached larger population sizes in Europe, or if modern human populations had grown slower, some of us today would probably carry a lot more Neanderthal ancestry in our genome," Juric said in a statement.
Future research could investigate which genetic variants from extinct relatives of modern humans were weeded out of the modern human genomes. "I would love to know which exact Neanderthal alleles were selected against," Juric said. "Once we know more about the genes involved, we can ask what those genes do and what traits they are involved with in modern humans. Then, we might be able to make some guesses about the traits of those early human-Neanderthal hybrids."
What Triggered Tsunamis that Demolished Bronze-Age Civilization?
What Triggered Tsunamis that Demolished Bronze-Age Civilization?

The historic eruption of the Greek volcano Thera in about 1650 B.C. triggered massive tsunamis and led to the end of the dominant civilization in the Mediterranean. Now, researchers say these destructive tsunamis may have been generated by the flow of volcanic material into the sea, challenging previous explanations, according to a new study.
Studies of the Bronze Age disaster led scientists to think the collapse of the volcanic crater (called the caldera) into the sea caused tsunamis after the eruption of Thera, on the island now known as Santorini. However, in the new study, scientists used volcanic and seismic data, along with detailed mapping of the seafloor, to disprove this theory and offer a new explanation.
Their research revealed that the caldera was not connected to the sea when it collapsed and, therefore, could not have caused the tsunamis. Instead, the researchers propose that large volumes of volcanic material flowing rapidly into the sea could have displaced enough water to create tsunamis. [The 11 Biggest Volcanic Eruptions in History]
Pyroclastic flows are fast-moving currents of volcanic material (rock fragments; lava; and hot, expanding gases) that flow down a volcano after an eruption. These flows can reach scorching temperatures of more than 750 degrees Fahrenheit (400 degrees Celsius) and move at speeds of up to 45 mph (70 km/h), the researchers said. As this material flows into the ocean, it solidifies and displaces massive amounts of water, they added.
"This violent entry of the pyroclastic flows into the sea triggered more than one tsunami," said study lead author Paraskevi Nomikou, a geologist and oceanographer at the National and Kapodistrian University of Athens in Greece.
Deposits of volcanic material up to 200 feet (60 meters) thick were found offshore Santorini, supporting the new theory, the researchers said.
Another famous volcano similarly triggered tsunamis: the eruption of Krakatoa, in Indonesia, in 1883. Tsunamis following the explosive Krakatoa eruption occurred when pyroclastic flows entered the sea, not because the caldera collapsed, Nomikou said. This well-recorded eruption caused more than 35,000 deaths and has been studied extensively by volcanologists. But the eruption of Thera may have been many times larger, and more destructive, according to the new study.
In fact, the eruption of Thera did more than blow a hole into the island and trigger tsunamis and flooding. The eruption also set off the decline of the Minoan culture, the dominant civilization in the Mediterranean at the time, the researchers said.
"The eruption was the beginning of the end of the Minoan civilization," Nomikou told Live Science. "The eruption occurred in 1650 B.C., and the end of the Minoan civilization was at 1450 [B.C.], so the civilization was destroyed completely, disappeared completely after 200 years."
To further understand just how violent and destructive the eruption of Thera was, Nomikou and her colleagues plan to continue their research on the pyroclastic flows.
"We know now that these flows caused so much damage in the area around Santorini like in Crete," Nomikou said. "So we need to better understand these flows and have the total volume of the eruption, because we believe that this was the most catastrophic event during the last 10,000 years."
The new research was detailed in a study published online today (Nov. 8) in the journal Nature.

Into the Abyss: Astronomers Are Trying To “See” a Black Hole for the First Time Ever
C. Malin ESO
IN BRIEF
The Event Horizon Telescope Project is scheduled to take the very first snapshot of a black hole's event horizon by April 2017.
Sagittarius A, the black hole in the middle of the Milky Way galaxy, sits more than 25,000 light years away from Earth.
PICTURE PERFECT
Next year, a network of radio telescopes will do something that’s never been done before: capture a picture of the mysterious inside of Sagittarius A, the black hole in the middle of the Milky Way galaxy. The Event Horizon Telescope Project is scheduled to take the very first snapshot of a black hole’s event horizon by April 2017.

The project consists of nine different observatories all over the world— located in the US, Chile, Spain, Greenland, France, and even the South Pole. And they’ll needall that power to get their shot.
“There are quite a few challenges that need to be overcome to take a picture of a black hole – it’s something that’s extremely small in the sky,” says EHT team member Feryal Ozel.
At 25,000 light years away, the black hole is just a pin prick. Ozel compares the size to us trying to see a CD sitting on our moon. To make it even more challenging, the black hole is surrounded by clouds of gas and dust.
Astronomers had to determine the right wavelength of light they would use for the process. They settled on 1.3mm, which can pierce the black hole’s dust clouds, allow hot gasses to shine brightly, and travel easily through the atmosphere.
PROVING PHYSICS
The end goal of this is not just to take pretty pictures. Ultimately, the EHT will prove one of the most fundamental tenets of physics: general relativity.
Einstein’s tenet says that black holes bend spacetime, and that we can calculate that bend. So the pictures we get from the EHT have to show a crescent, and it has to be bent the right way, or else something is wrong with our physics models.
“We know exactly what GR predicts for that size,” Prof Ozel said – making this observation what scientists call a “null hypothesis test” of the theory.
Ultimately, projects like the EHT allow us to prove what were only theories decades ago, and teach us a lot about the workings of the universe in the process. Technology is helping us to better see (and understand) our universe.
Paralyzed Monkeys Able to Walk Again With Brain Implant. Human Trials Are Next
Paralyzed Monkeys Able to Walk Again With Brain Implant. Human Trials Are Next
A neural interface helped a monkey walk again after its spinal cord was cutSwiss Federal Institute of Technology in Lausanne

IN BRIEF
Using a system of electrodes, transmitters, receivers, scientists were able to restore leg function in a primate, completely bypassing damaged nerves.
While this remarkable feat may be decades away from human use, it is a promising development for the hundreds of thousands of people in the U.S. with spinal cord injuries
Gregoire Courtine, a neurologist at the Swiss Federal Institute of Technology, holds a silicone model of a primate's brain with an electrode array. The goal is to pick up signals from the brain and transmit them to the legs.

INSTANT FUNCTION
Electrodes implanted in the brain and spine have helped paralyzed monkeys walk. The neurologists behind the study reported that the implants restored function in the primates’ legs almost instantaneously. The findings are detailed in Nature.
The spinal cord of the subject monkey was partially cut, so the legs had no way of communicating with the brain. To mend the brain-spine interface, electrodes were placed on key parts of the monkey’s body. Implants were placed inside the monkey’s brain at the part that controls leg movement, together with a wireless transmitter sitting outside the skull. Electrodes were also placed along the spinal cord, below the injury.
A computer program decoded brain signals indicative of leg movement and transmitted the signals to the electrodes in the spine. Within just a few seconds, the monkey was moving its leg. In a few days, it was walking on a treadmill.
Alain Herzog/Swiss Federal Institute of Technology (EPFL)
“The primate was able to walk immediately once the brain-spine interface was activated. No physiotherapy or training was necessary,” said Erwan Bezard, one of the authors of the study.
PRIMATE-TO-PRIMATE
This study is a massive breakthrough—it’s the first time implants have helped a primate walk. There has been much research to develop tech for paralyzed patients, but most lab trials were done on rodents. “It seems the principles learned in rats are now translating into primates,” said Jen Collinger, a University of Pittsburgh bioengineer.
The results were astoundingly positive, but the researchers say that it will take at least a decade to fine-tune the technology for use in humans. Still, our bodies are greatly similar to that of monkeys, and the researchers believe transition could be quick.
Exciting news about the study is that the components that the researchers used are legal for human use in Switzerland. The Swiss group of the study have started clinical trial with eight people with partial leg paralysis.
We’re all eager for further development in the study—an innovation that could greatly change the lives of approximately 282,000 people in the U.S. with spinal cord injuries.
This amazing structure was found by Streetcap1. The building is on Earths moon and is one of the three types that I have often talked about. Type 1, the white ceramic structures (medium size and have 90 degree angles). Type 2 the large non reflective black structures (mountain size, but biomechanically grown and have curved edges most of the time). Type 3, the grey metallic structures (these are small, 100 meters or less and are most often near the edges of the large black structures and have 90 degree angles). Scott C. Waring-Taiwan
A pinging sound was in the Hecla Strait, so I got out Google Earth and started looking for the alien base causing it. It took a whole 5 minutes, but I found it. Check out the buildings I found both on the land and mostly in the shallow water. The right angle of the buildings is unmistakably intelligently made. This is or at least was, an alien base, but since its still making a pinging noise...its probably still populated. The pinging could also be an old distress signal, accidntly set off from an invasion of privacy. Maybe a local accidentally found one of the thousands of underwater structure and entered, and this could set of an alarm. Scott C. Waring-Taiwan News states: A strange "ping" is emanating from the Arctic Ocean, according to reports from hunters and boaters in Canada's Nunavut territory. The noise has been occurring for months, dating back to summer, and it correlates with fewer sightings of marine animals nearby. Some local hunters worry it's scaring away wildlife. Also described as a hum or beep, the mysterious sound seems to come from the seabed in the Fury and Hecla Strait, a narrow channel in the Qikiqtaaluk Region of Nunavut. It's a remote area, about 120 kilometers (75 miles) from the hamlet of Igloolik, located within a stretch of open water surrounded by sea ice. Known as a "polynya," this type of habitat is normally a popular hangout for wildlife. "That's one of the major hunting areas in the summer and winter because it's a polynya," Nunavut legislator Paul Quassa tells the CBC. "And this time around, this summer, there were hardly any [animals]. And this became a suspicious thing." (More at Source).
UFO Buzzes Over Washington DC On Day Trump Is Elected US President, Nov 9, 2016, UFO Sighting News.
UFO Buzzes Over Washington DC On Day Trump Is Elected US President, Nov 9, 2016, UFO Sighting News
Date of sighting: Nov 9, 2016 Location of sighting: Washington DC, USA This UFO was seen today over Washington and in one part of the video, the UFO comes into focus as it tilts slightly so we can see its top surface. Its a half disk shape and should not be over Washington without being intercepted by several F16s which watch this airspace. Apparently this UFO didn't show up on radar. US radar towers have not been updated much since its invention and need a serious upgrade to catch UFOs in US airspace. Its my belief that this UFO was over Washington to see how Obama was taking the news of the next US president being Trump. Will Trump reveal UFO info to the public, or will he skirt this issue? Scott C. Waring-Taiwan Eyewitness states:
Check this out Angel Spotted in the sky this afternoon over Washington D.C. whats the meaning of this awesome sighting.
China Sends a Team of Astronomers to New Antarctica Observatory to Probe Extraterrestrial Life
China Sends a Team of Astronomers to New Antarctica Observatory to Probe Extraterrestrial Life
China’s construction of an astronomical observatory is close to completion at the highest point on the Antarctic plateau as the 33rd Chinese expedition to the frozen continent starts. The missions to the South Pole hope to know the origin of dark matter and extraterrestrial life.
Aboard the research icebreaker Xuelong (Snow Dragon) are four astronomers who have planned about 100 projects for the next nearly six months of travel. They have 20 days to work at Kunlun base, according to one of the scientists.
Since 2007, China has sent astronomers every year to the region to build an observatory on Dome Argus, nearly 750 miles or 1,200 km from the nearest coast and around 4,093 meters or over 13,400 feet above sea level as the highest point.
The Kunlun station was built in 2007, located 7.3 km from Dome Argus, where it has been preparing since for its observation center.
With an automated astronomical observation platform at Dome Argus, the country is now planning to build a high-elevation Antarctic terahertz telescope.
UFO Hunters Discover “Alien Structures” on Mercury
UFO Hunters Discover “Alien Structures” on Mercury
Truth researchers found what they call alien buildings after looking through NASA photos from Jet Propulsion Laboratory team, who send robotic probes for the Solar System exploration.
Experts claim that the discovery of alien buildings on the first rock from the Sun isn’t the first time.
Pictures seem to show 17 structures in dome shape around the craters’ edges on Mercury.
Bumps across the surface of the planet are found in photos taken from one of NASA’s orbiters.
However, instead of considering them as natural formations, some UFO hunters believe these dome-shaped structures are of alien origin.
Just last week, some extraterrestrial enthusiasts identified an alien moon base in pictures taken from lunar orbiter of NASA.
Referring to the dome-shaped formations, truth seekers suggest these structures show something other than what scientists think.
Mercury has temperature highs of about 900C and lows of -173C. Life, as we know it, would be almost impossible to exist in the smallest planet of the Solar System. Furthermore, liquid water cannot exist on its surface.
The planet also experiences frequent solar storms and asteroid impacts.
Government Asked Pilots Not To Discuss Their UFO Sightings With Media
Government Asked Pilots Not To Discuss Their UFO Sightings With Media
In the 1950s, UFO sightings reported by pilots – military or civilian – could be the biggest headache for the American Air Force to cover-up. Civilian UFO sighting reports could be questioned or even discarded because of the fact they don’t possess knowledge and expertise to come to conclusions about the UFO. This wouldn’t be the case if civilian and military pilots identified UFOs. However, according to many UFO conspiracy theorists, the American government was prepared for the latter scenario.
The U.S. Air Force allegedly implemented the policy of silencing its Air traffic controllers and pilots. The Air traffic controllers and pilots who reported UFO sightings were reportedly provided with Communication Instructions for Reporting Vital Intelligence Sighting (CIRVIS), which detailed procedures to follow in case they encountered a UFO.
The top U.S. Air Force officials allegedly had a meeting on February 17, 1954, with the representatives of the U.S. top airlines. Before the meeting took place, commercial pilots reported UFO sightings on the average of five to ten per night. Instead of sending reports about their UFO sightings directly to their companies, commercial pilots are instructed to report them to the nearest Air Force base or the Military Air Transport Service (MATS) intelligence in Washington.
Pilots were also asked not to discuss their UFO sightings to the public or share them to the newspaper. Hundreds of pilots gathered together and protested against this government instruction. They even sent a petition to the government, but to no avail. Even at present, pilots are discouraged from discussing their encounters with UFOs to anyone from the media or press.
As an observational astronomer who teaches students about the behavior of the moon, I'm thankful for anything that inspires people to go out and look at the sky. For me it's second nature to pay attention to the moon; when my son was born, I would take him out at night to observe with me, and one of his very first words was "moon."
But I have mixed feelings about what's being billed as the upcoming "super-supermoon." Many astronomers do not like using the term because reports overhype the factors that make certain full moons unusual. Most of what you've likely read has probably misled you about what you can expect to see on Nov. 14 and just how rare this event is. Beautiful, yes. Worth looking up for, definitely. Once in a lifetime… that's a bit overblown.
The moon's cyclical phases
Just about everyone is familiar with the moon's changing appearance as it goes through its phases from crescent, to half-illuminated (first quarter), to gibbous, to full, and then back through gibbous, to half-illuminated (third quarter), to crescent, to new.
This pattern occurs because the moon orbits the Earth. When the moon is between the Earth and sun, it's a new moon, and you don't see it that day. When the moon is on the opposite side of the Earth from the sun we get a full moon as the sun's light illuminates almost its entire face. The complete sequence of phases takes about the same amount of time as it does for the moon to orbit the Earth once — just about a month.
As the moon makes its monthly trip around our planet, it travels on an elliptical, not circular, path. Every object in the solar system orbits like this, including the Earth around the sun; over the course of the year, the Earth is sometimes closer to the sun and sometimes more distant. Same for the moon — sometimes it's closer to us and sometimes farther away.
The changes are proportionally not large; at "perigee" (the closest it gets to the Earth) the moon's approximately 10 percent closer to the Earth than at "apogee" (most distant point on its orbit). Over the year, the moon's distance from Earth varies from around 222,000 to 253,000 miles.
The time it takes the moon to go from perigee to perigee (about 27.3 days) is shorter than the time it takes to go through a complete set of phases (about 29.5 days). Because these timescales are different, the phase at which perigee occurs varies. Sometimes perigee occurs when the moon is full, but it is just as likely for perigee to occur when the moon is in the first quarter phase, or any other. Whichever phase the moon is in when it's at perigee will be the one that looks largest to us here on Earth for that month.
At perigee, the moon can appear 14 percent larger and 30 percent brighter than an apogee full moon. But this is complicated by the fact that our eyes play tricks on us and convince us the moon looks larger when it is near the horizon than when it is higher in the sky. Every full moon will look big and bright whether it happens at perigee or apogee.
So what's a supermoon?
The first time I heard the phrase "supermoon" was in 2011, and someone had to explain the suddenly in vogue term to me. People were using it to describe the full moon that happened to occur within an hour of perigee in March of that year. The moon's perigee distance also varies a bit, and March 2011 was the moon's closest perigee of that year.
This was a somewhat rare event – a full moon occurring not just at perigee, but at the closest perigee of the year. But many people got the impression that this was an exceedingly unusual event, and rushed to see and capture images of this supposedly ultra-rare moon. Depending on how closely you require the full moon to occur to perigee in order to call it a supermoon, though, these events happen at least roughly once a year, and often more frequently.
Which brings us to this month's much ballyhooed "super-supermoon." News stories are hyping the upcoming full moon as a once-in-a-lifetime viewing opportunity. It's true that the Nov. 14 full moon is the closest since 1948, and the next time the full moon will be closer is in 2034.
But this month's full moon is only 0.02 percent closer – a mere 41 miles! – than the March 2011 supermoon. These tiny distances make no noticeable difference in the moon's appearance.
Please do go out and observe the November full moon. If you are good with photography, try to document that the moon does appear larger than the other months this year. Just be aware you'll have other virtually equivalent opportunities to do so pretty much every year for the rest of your life. So don't worry if you miss it. You can catch the supermoon next time around.
Do UFOs exist? Are aliens real? Could there be aliens living among us? These questions have been plaguing us for many centuries, even thousands of years. UFO news 2016reportsclaimed of a “disk-like” UFO passing the moon, raising opinions that aliens were investigating the moon.
HOLLYWOOD STAR CAUGHT A UFO SIGHTING
UFO news 2016 reports on child actress Rowan Blanchard sighting of a UFO in New York City. She published a photo on her Instagram where she caught a UFO sighting on her phone.

Girl Meets World Rowan Blanchardsaid on her Instagram post, “Say what u will but that thing was just appearing in the photo and wasn’t physically there.” Her photo shows an alien-like spaceship glowing in the clouds.” Whether it’s an alien ship or not, it is up to the viewers to decide.
MULTIPLE UFO SIGHTINGS OVER THE YEARS?
Meanwhile, UFO Chronicles posted a tweet about a UFO sighting in 1984 of a “flying saucer.”
Reports claim that aliens have visited our planet and could be living among us, but that has not been confirmed nor debunked yet. UFO Sightings posted this picture of an alien in Twitter with a caption “Area 51 Scientist Smuggles Alien Photograph, Explains On His Deathbed Aliens Are Real.”
Although this has not been confirmed with evidence or declared edited, this is an interesting picture that could possibly reveal more about aliens.

The Courier reports UFO news 2016 of sightings and aliens living among us. It says that the UFO sightings on Falkland specifically “On September 23, 1996, two adults, a teenager and a 10-year-old driving near Newton of Falkland claimed they saw not only a large black triangular shaped ‘craft’ but numerous small grey ‘beings’ in front of some woods.”
There were also reports of aliens trying to contact us. Mirror reports about a Russian telescope receiving alien broadcast signals from outer space.
“A Russian radio telescope discovered the signal coming from a star in deep space, raising the possibility of intelligent life beyond Earth…Strange signals are thought to be coming from the star HD164595, which is located in the Hercules star constellation,” Mirror reports.
There is not much solid evidence about aliens and UFOs until now. The strange sightings still cannot be substantially explained by science as public records can show. Do you know any UFO news 2016 story that seems authentic? Let us know in the comments section.
