Doemdagklok weer minuut dichter bij Apocalyps: “Het is twee voor twaalf” - HLN.be

Bron: Washington Post, CBC

De klok, die in gebruik is sinds 1947, is een metafoor die aangeeft hoe dicht we staan bij de vernietiging van de aarde. Een groep wetenschappers en nucleaire experts die zich gezamenlijk het ‘Bulletin of the Atomic Scientists’ noemen, komen op regelmatige basis samen om de tijd op de Doemdagklok te bespreken.

Waarom het einde van de wereld echt nabij is, volgens deze wetenschapper

“Met grote bezorgdheid passen we de Doemdagklok vanaf vandaag aan,” zegt Rachel Bronson, voorzitter en CEO van het Bulletin: “Het is nu twee minuten voor middernacht”.

Nucleaire en klimaatbedreigingen

De organisatie doet de nieuwe aanpassing omdat “president Trump en andere wereldleiders er niet in slagen om de op de loer liggende bedreigingen van een nucleaire oorlog en de klimaatverandering aan te pakken,” luidt het.

“De wereld is nu niet alleen gevaarlijker dan een jaar geleden: het is van Wereldoorlog II geleden dat de situatie nog zo dreigend was,” schrijven Lawrence M. Krauss en Robert Rosner, twee medewerkers van het Bulletin in The Washington Post. “De Doemdagklok staat in feite even dicht bij middernacht als in 1953, toen de vrees om de Koude Oorlog mogelijk op haar hoogtepunt was.”

De oplopende spanningen tussen de VS en Noord-Korea dragen volgens de wetenschappers bij tot de aanpassing van de Doemdagklok. “Zeggen dat de nucleaire toestand van de wereld schrijnend is, is een onderschatting van het gevaar en de hoogdringendheid,” zeggen Kraus en Rosner.

Nog slechter dan een jaar geleden

Vorig jaar stelden de wetenschappers de klok nog met een halve minuut bij, van 23:57 naar 23:57:30. “De waarschijnlijkheid van een globale catastrofe is erg hoog en de acties die nodig zijn om de risico’s op een ramp te verkleinen moeten erg dringend genomen worden,” stelde het Bulletin toen.

De eerste keer dat de Doemdagklok werd bijgesteld na haar ingebruikname in 1947, was twee jaar later, nadat de Sovjet-Unie met succes haar eerste atoombom testte. Toen schoof de wijzer van de klok van 23:53 uur naar 23:57 uur.

Het gebeurde nog maar één keer dat het alarmpeil even hoog stond als vandaag: in 1953 gaf de klok aan dat het twee voor twaalf was nadat zowel de VS als de Sovjet-Unie succesvolle proeven met kernbommen hielden binnen een tijdsspanne van amper zes maanden.

In 1991 leek de wereld er het best voor te staan, toen stond de wijzer op 17 minuten voor middernacht.

Verkiezing van Trump

“Telkens wanneer de klok wordt aangepast, beantwoorden we twee vragen,” zei Rachel Bronson vorig jaar in een interview: “Is de wereld veiliger? Of loopt ze een groter risico dan een jaar geleden? En is het veiliger of een groter risico dan ooit eerder in de geschiedenis van de klok?”

Met de aanpassing vragen de wetenschappers aandacht voor wereldwijde crises die volgens hen het bestaan van de mensheid in gevaar brengen. Daarbij richten de wetenschappers de aandacht op de beschikbaarheid van kernwapens en de bereidheid van de wereld om ze te gebruiken. De laatste jaren brengen ze ook de dreigende klimaatverandering mee in rekening.

De organisatie haalde vorig jaar ook de verkiezing van Donald Trump aan als een belangrijke factor, “omdat hij beloofd heeft de vooruiting op beide fronten (kernwapens en klimaatverandering, red.) te verhinderen,” schreven twee leden van het Bulletin vorig jaar. “Nooit eerder heeft het Bulletin beslist om de klok vooruit te zetten voornamelijk omwille van de stellingen van slechts één persoon. Maar wanneer die persoon de nieuwe president is van de Verenigde Staten, dan doen zijn woorden ertoe.”

Symbolisch

Het Bulletin beklemtoont dat de klok symbolisch is en enkel dient als “dringende waarschuwing voor globaal gevaar”.

“We hopen dat de bijstelling van deze klok geïnterpreteerd zal worden zoals ze bedoeld is: als een dringende waarschuwing voor globaal gevaar. De tijd voor wereldleiders om het op de loer liggende nucleaire gevaar en de voortdurende opmars van de klimaatverandering aan te pakken, is al lang voorbij. Het is nu de tijd voor wereldburgers om dringende maatregelen te eisen. Het is tijd om de Doemdagklok terug te draaien,” stellen ze.

In het geheim gelanceerde discobal schijnt als helderste ster aan de hemel -  HLN.be

BRON : The Guardian

Het nieuwe ruimtevaartbedrijf Rocket Lab breidde onze sterrenhemel vorige vrijdag een beetje uit. De start-up lanceerde toen in alle stilte een raket in een baan rond de aarde. Dat deed het vanop een schapenboerderij op het schiereiland Mahia in Nieuw-Zeeland.

De lancering zorgde voor veel gejubel en trots in Nieuw-Zeeland. Peter Black, oprichter en CEO van het opkomende Rocket Lab, sprak van een bijna ongeëvenaarde stap in de commerciële verkenning van de ruimte.

Discobal

Wat er zo spectaculair is aan de raket, is dat ze naast de klassieke conventionele raketten ook de ‘Humanity Star’ draagt. Die nagemaakte ster bestaat uit een drie meter brede bol en is gemaakt van koolstofvezel. Verder is ze uitgerust met 65 sterk reflecterende panelen en draagt ze daardoor de bijnaam ‘discobal’.

Volgens het bedrijf zal de bol de stralen van de zon naar de aarde weerspiegelen en een knipperlicht creëren dat overal ter wereld zichtbaar is. Er wordt zelfs verwacht dat hijvoor negen maanden lang het helderste object aan de sterrenhemel zal zijn en pas zijn helderheid zal verliezen wanneer hij opnieuw de aardse atmosfeer bereikt.

Volgens Rocket Lab moet de ster een herinnering zijn aan onze kwetsbare plek in het universum. Black voegt daar aan toe dat de bol harmonie en een gedeelde ervaring voor iedereen op de wereld zal creëren.

Lichtvervuiling

Toch blijkt de functie van de spectaculaire uitvinding niet geheel rozengeur en maneschijn. Omdat het hun onderzoek belemmert, vormt lichtvervuiling nu al een enorm probleem voor astronomen. De introductie van een glinsterende discobal in de ruimte wordt dan ook niet overal toegejuicht.

Over de hele wereld uiten astronomen zich op zowel gefundeerde als minder diplomatieke manieren over de Humanity Star. Zo vertelde professor Richard Easter aan The Guardian dat Rocket Lab onbedoeld zijn beroep bijzonder zwaar getroffen heeft en ook zijn collega’s winden er op Twitter geen doekjes om.

Wat er nu gaat gebeuren met de lichtgevende discobal in de ruimte en of hij al dan niet verwijderd zal worden, is nog niet duidelijk. Voor wie de bol nog zou willen waarnemen kan op een online map steeds contoleren waar de bol zich precies bevindt en in welke richting moet worden gekeken om hem goed waar te nemen.

Flying Saucer becomes visible in the sky over Jamaica

A strange phenomenon appeared in the sky over St. Ann, Jamaica on January 25, 2018.

Stoney Vill, who has filmed the phenomenon, wonders what the strange ring of lights in the clouds could be.

The video shows sun rays shining from behind a cloud formation, but light from the sun seems to be bending around a disk at the top of the cloud

When zoomed in on the disk, it clearly shows the solid contours of a UFO, a cloaked flying saucer that became temporarily visible. (See video 0.06sec).

LSU professor debunks alien megastructure myth

26-01-2018 om 00:07 geschreven door peter  

• A professor from Spain says we’re not ready to meet extraterrestrial life
  
• Gabriel De la Torre surveyed 116 students from the US, Italy and Spain
• He found that many had a lack of knowledge in a number of areas
• They also had religious beliefs that would make finding ET a ‘big shock’
• We also focus too much on daily problems than bigger things like Earth
• He concludes we need to improve our ‘global consciousness’

Finding extraterrestrial signals has been dreamed about for decades.

But a researcher from the University of Cádiz in Spain says we shouldn’t be looking – because we’re not ready to meet aliens.

Gabriel De la Torre revealed to MailOnline how his survey of students showed the general level of ignorance and influence of religion would leave us shocked if we made first contact.

A study by Professor Gabriel De la Torre from the University of Cádiz in Spain claims that we’re not ready to make first contact. He claims we’re not prepared mentally or ethically to meet beings unlike ourselves and we should try to improve our ‘global consciousness’

Since 1984 the Search for Extraterrestrial Intelligence (Seti) Institute has been looking for signs of intelligent life elsewhere in the universe.

To date nothing has been found, although the search continues unabated.

Members of the project are now going further by sending out messages from Earth (Active Seti) to try and contact other lifeforms.

But De la Torre, a professor in the Department of Psychology at the University of Cádiz and participant in previous projects such as Esa’s Mars 500 (a simulated mission to Mars on Earth), has carried out a study that he claims indicates we are not ready to make contact.

In the study he sent a questionnaire to 116 students in Spain, the US and Italy.

De la Torre tells MailOnline he used students because they ‘will be the future politicians, scientists, the people in charge, so I wanted to know what their knowledge was.’

THE RESULTS AT A GLANCE

The Search for Extraterrestrial Intelligence (Seti) Institute was established in 1984. Since then it has used a number of observatories around the world, like the Allen Telescope Array (pictured), to try and find alien signals from another world, but so far nothing has been found.

The questions were split into five sections: religious beliefs, the environment, space-related knowledge, their daily activities and their opinions on life issues.

‘In all those areas I defined a different type of question based on other studies that I think related to Seti research,’ De la Torre says.

These included questions such as how likely they thought life was to exist on other planets, what year man first walked on the moon and what the largest planet in the solar system is.

The results were somewhat disconcerting for De la Torre. For example only 82 per cent of the students knew the first moon landing was in 1969.

‘The conclusions were that scientific knowledge, especially the knowledge related to space among college students, is not good,’ he continues.

‘So I think space agencies should increase education efforts.’

On 16 November 1974 the Arecibo radio telescope in Puerto Rico (pictured) was used to send out a signal called the Arecibo message, a ‘calling card’ from Earth to potential alien races. However De la Torre says we shouldn’t perform ‘Active Seti’ like this as we aren’t ready to make contact

But ultimately it is our lack of appreciation for our own planet and our place in the universe that would be our downfall, he says.

‘We’re not ready to talk to extraterrestrials because global consciousness is not developed enough in the population,’ he concludes.

‘People have daily life problems and the government doesn’t pay attention to global issues like the planet and the environment.

‘That makes us a species too focused on daily life problems, we don’t have an awareness of our surroundings.

‘It’s like when a meteor falls in some place on the planet, it’s big news. But that’s a regular real possibility.

‘If we have a more global consciousness about our situation on the planet, how fragile the planet is, maybe that’s a step in the evolution of our consciousness as a species.

‘There could be other intelligent life out there and it could be really different from us physically, mentally, socially and even morally.

‘They could maybe not even be biological, they could be robots.

‘Right now I don’t think as a species we are ready.

‘Of course some people are ready, but as a species I think it would be a big shock.’

NASA's Bold Plan to Save Earth From Killer Asteroids - Alien UFO Sightings

Just beyond Earth’s home in the solar system, about 94 million miles from the Sun, a coal-black asteroid slowly rotates as it orbits our star. It’s about 1,650 feet across, with a slight bulge around the middle, like a spinning top. Its low density means it’s not solid, but instead it’s likely a crumbly pile of carbon-rich rocks held together by gravity.

The asteroid is called Bennu, and every six years, its egg-shaped orbital path brings it just 185,000 miles from Earth — roughly 53,000 miles closer than our moon. In about 200 years, there’s a 1-in-2,700 chance it could sail close enough for Earth’s gravity to reel it in. That would be very bad.

The impact would excavate a crater nearly three miles wide and 1,500 feet deep. Locations three miles away would be buried under 50 feet of rock raining down. It would trigger a 6.7-magnitude earthquake. But the real damage would come from the air burst, caused by the meteor hurtling through the atmosphere, which could collapse buildings and tear down trees up to 30 miles away.

Luckily for us, asteroids the size of Bennu, and giant asteroids like the one that helped kill the dinosaurs 65 million years ago, don’t cross Earth’s path often. But smaller ones do all the time. They enter our atmosphere as meteors, where many blow up in mid-air; some make their way to the ground or sea. The good news is that we’re getting better at finding them — but we’re still unprepared if one does make its way to Earth.

Partly to help with this, a NASA spacecraft called OSIRIS-REx is on its way to Bennu, where it will collect several pounds of asteroid samples and return them to Earth. By baking those samples and melting them down, scientists will learn what the asteroid is like, how the solar system’s rocky worlds were made, and how to protect Earth from these errant rocks — whether by pushing them away, breaking them up, or using the sun’s warmth to nudge them a different direction.

In that way, Bennu may become the asteroid that saves us all.

NASA is on an asteroid binge these days. Earlier in January, the space agency announced it is planning two more missions to these solar system crumbs over the next few years. The Lucy spacecraft will fly to Jupiter and study its Trojan asteroids, which trail behind the giant planet. The Psyche mission will travel to an iron asteroid thought to be a leftover planetary core, whose mantle and crust were lost to time and fiery collisions.

These explorations will provide planetary scientists with a wealth of new information, says Bill Bottke, who studies asteroids at the Southwest Research Institute in San Antonio.

“Locked in asteroids are stories that are telling us what was going on when the planets formed, when the solar nebula was still around,” he says. What processes does it take to form a planet?”

Fortunately, asteroid studies also tell us what it takes to wreck a planet.

As Bennu whirls around its axis, its inky surface absorbs sunlight like asphalt on a hot day. As it rotates into the dark, that warmth radiates into space and it cools down again. This temperature change gives the asteroid a tiny nudge, called the Yarkovsky effect, which over time will change its orbit.

One of OSIRIS-REx’s main goals is to measure this phenomenon, says Daniel Scheeres, an astronomer at the University of Colorado who works on the project.

“After the mission, we should be able to update all these impact probabilities, and hopefully it will go down,” he says. “Just by testing the theory and validating it with more precise measurements, that can help all of our other predictions of the Yarkovsky effect for all other asteroids.”

Right now we know of about 723,367 asteroids in the solar system, and astronomers from universities and observatories around the world discover new ones almost every day. Based on statistical analysis and detailed searches, scientists think they’ve found more than 90 percent of asteroids about half a mile wide or larger, each of which would cause global extinctions if they impacted earth.

Dedicated searches have also found about 25 percent of the asteroids that measure at least 460 feet across, or roughly the size of a football stadium. But more than a million small asteroids — like one the size of a city bus that exploded over Chelyabinsk, Russia, three years ago — are thought to be out there.

Last year, NASA consolidated its asteroid-hunting efforts under a new program called the Planetary Defense Coordination Office, which finds and tracks new objects and will issue warnings about possible impacts. Its budget for the current fiscal year includes $50 million for near-Earth asteroid observations and planetary defense, which is a tenfold increase since the beginning of the Obama administration.

But NASA isn’t the only one hunting asteroids. The Japanese Aerospace Exploration Agency has already brought back bits of one asteroid, and has another mission en route to a second. The privately funded B612 Foundation, named for the asteroid in the French children’s story “The Little Prince,” is still looking for a cash infusion of $450 million to send its telescope into space to look for near-Earth asteroids.

But all this work to find asteroids and to visit them won’t mean much if we can’t do anything about it. There are a few ways to save Earth from an asteroid. We could push it out of the way, essentially using celestial mechanics to ensure it won’t get pulled in by Earth’s gravity, or we could try to destroy the asteroid before it has a chance to destroy us.

The decision depends on how much time we have and what the asteroid is like, says Jason P. Dworkin, OSIRIS-REx project scientist at NASA’s Goddard Space Flight Center in Greenbelt, Md. Some asteroids might be easy to crumble into pieces; some could break apart into smaller stones that hit Earth in multiple places. Others might require a really big shove.

“If it was up to me, I would send a rocket with some titanium dioxide on it and paint it white, and have that Yarkovksy effect accelerate, and move it away from the Earth,” Dworkin says. Titanium dioxide is a common ingredient in sunscreen, and it looks chalky white. A spacecraft could fly to a dangerous asteroid, enter orbit around it, and spray-paint it.

“If you have something like 50 years, that could deflect it enough, and it might be a whole lot simpler than sending up nuclear weapons,” Dworkin says.

NASA

If that doesn’t work, a nudge might do the trick. NASA and ESA plan to study this with a mission called the Asteroid Impact and Deflection Assessment (AIDA), which will slam a satellite into an asteroid in 2020.

If we don’t have 50 years or a fast enough battering ram, we might need to break up an asteroid instead. Catherine Plesko of Los Alamos National Laboratory uses supercomputers to study how to break up asteroids using nuclear explosions and “kinetic impactors,” essentially giant space cannonballs.

“Cannonball technology is actually very good technology, because you’re intercepting the object at very high speed, so it ends up being more effective than conventional high explosives,” Plesko said at a meeting of the American Geophysical Union in December. “If you really need a lot of energy, though, a nuclear burst is the way to get the largest amount of energy out to the object in the smallest possible container.”

Her simulations include equations that describe how fluids flow; the boiling and melting points of rocks depending on their densities; how light and energy propagates; and other physics. Then she can slip in a model for a given asteroid, and see how it responds to a cannonball.

If Earth decides to nuke it instead, the blast wouldn’t have to blow up the asteroid from within. The plan would entail launching a rocket with the bomb as its payload (a risky prospect, should it blow up on the launchpad) and aiming right for the asteroid. Exploding the bomb at the asteroid’s surface could disrupt its interior enough to break it apart, shifting its course and limiting the threat to Earth.

“For nuclear deflection, it really is the best idea to do an intensive load of these calculations before we even need to contemplate doing anything real,” Plesko says.

If we do need to do something real, it won’t happen overnight. It takes at least five years to design, build and launch a spacecraft that can deflect or destroy an asteroid or comet, according to astronomer Joseph Nuth of Goddard. He says humans would be wise to build a spacecraft now, and ideally two: an observer that could be quickly dispatched to learn more about the asteroid, and an interceptor that could deflect it.

“If we build it now on a normal schedule, and put that interceptor into storage, we can launch it in less than a year,” he explained at the AGU meeting. “This could mitigate the possibility of a sneaky asteroid coming in from a place that’s hard to observe, like toward the sun.” (The Chelyabinsk meteor was one such asteroid.)

No space agency has a deflector mission yet, but scientists know a lot more today than they did even 15 years ago, Bottke says.

“There was a time where we didn’t have a program to look for objects, and it was done privately. You had guys like [astronomer Eugene] Shoemaker driving out every month to Palomar Observatory to look for them,” Bottke says. “Now we have $50 million annually to look for them. Now we’re getting serious science missions to look at these.”

Bottke and others say the increased awareness of asteroid threats has also been a boon for science, and for the people who study asteroids not only as harbingers of doom, but as messengers from Earth’s creation.

“The probability that any large asteroid is going to hit is in the near future is pretty low,” Bottke says. “So I tend to focus on the more uplifting parts of asteroids.”

"Mordor Under the Sea" Images Would Terrify Even Sauron

The submarine volcanic wasteland exists off the coast of Australia.

By Peter Hess

We all know Mordor, the volcano-peppered wasteland where Sauron dwells in the Lord of the Rings trilogy, is a fantasy land, right? … Right? Don’t be so sure. As fortune would have it, geologists have discovered a landscape that bears an uncanny resemblance to Mordor — under the ocean.

In some ways, the Voynich Manuscript is one of the most mysterious texts known to historians. The text is filled with fantastic, surreal imagery depicting plants, astronomical drawings, strange creatures, and a variety of dreamlike scenes. The origin of the text is unknown, but radiocarbon dating of the vellum it was written on puts its date of creation somewhere in the early 15th century. The book has changed hands numerous times throughout the centuries, passing from alchemists to rare booksellers and even to the King of Hungary. Today the Voynich manuscript resides in Yale University’s Beinecke Rare Book and Manuscript Library. The 240-page manuscript is written in an unknown language and script and has so far proven undecipherable even by the world’s most skilled cryptographers.

The manuscript is also full of these strange scenes of “nymphs.”

Every year or two, however, someone claims to have deciphered at least part of the manuscript, with most of the clues suggesting it was some type of pharmacopoeia or botany manual. Of course, one could surmise as much just by looking at the pictures. Just this week, however, a pair of Canadian artificial intelligence researchers claims to have developed an AI algorithm capable of deciphering the entire manuscript. Has the mystery of the Voynich manuscript finally been solved?

Curiously, many of the plants depicted in the manuscript resemble no known plants or flowers. Known on Earth, anyway.

Well, not exactly. But we might be getting close. The University of Alberta’s Greg Kondrak and Bradley Hauer claim to have developed an AI algorithm capable of deducing the language a text was written in with 97% accuracy. According to their algorithm, the Voynich manuscript was likely written in Hebrew and then encrypted using a substitution cipher in which letters are shifted, and the vowels have been removed from words. Kondrak and Hauer’s algorithm found that the first sentence of the text translates as “She made recommendations to the priest, man of the house and me and people.” In its analysis of the first 72 words of the manuscript, the algorithm has identified “farmer,” “light,” “air” and “fire” as the four most common words, with “covfefe” coming in a close fifth.

I knows gobbledygook when I sees it.

While this development is being hailed as a breakthrough in the quest to decipher the Voynich manuscript, the researchers themselves note that their work is far from complete and that hours and hours of human research are still needed to interpret the syntax and meaning behind the words. Will we ever really decipher the Voynich manuscript? What if it was written in gibberish and filled with curious images as a hoax or practical joke? Personally, I find that to be the most likely of all scenarios. And how hilarious would that be, writing a book of nonsense that gets pored over by learned men for centuries? If that’s the case, the author was a comic genius.

It allegedly happened over 60 years ago and at least one government official was a witness to extraterrestrials and their spaceship, which was visited and photographed by two other people. No, this isn’t about the event you’re thinking of … and not that other one you’re thinking of either. According to a new book about UFOs set to be published next month, this occurred in Italy in October 1957 and, while known in that country, has photos that have never been revealed outside of Italy until now. Do you want to believe?

“These rare and extraordinary photographs, as well as two photographs of the alleged extraterrestrial pilot… have been published here for the first time.”

The book is called “UFO Contacts In Italy: Volume One : 1907 – 1978” and it’s described as “a limited selection of some of the most impressive and interesting events from over 12,000 UFO Italian cases CUN has in its files and occurred in Italy during the 20th century.” CUN is Centro Uufologico Nazionale, the National UFO Center of Italy. A nonprofit founded in 1966 to collect information on UFO and alien encounters. The book devotes chapters to specific incidents (“1936: Italian Air Force idroplane formation intercepts a UFO over the Thyrrenian Sea”; “1951: A CE3 with six UFO entities near Ferrara”), time periods (The early Sixties: 1961-1964”; 1957-1958 Strange Sightings) and similar groups (“WWII UFOs”). In addition to detailed reports, the book includes a number of cases that have photographic evidence.

The author of “UFO Contacts In Italy: Volume One : 1907 – 1978” is Dr. Robert Pinotti, the founder of the National UFO Center (CUN) who is considered to be a leading expert in European UFO sightings. In that capacity, he has acted as a UFO consultant for the Italian government and claims to have seen secret documents on encounters from the Italian Department of Defense.

Yeah, yeah, yeah. What about the photos of aliens and the inside of their ship?

Pinotti claims the photographs (seen here) were taken in October 1957 in Francavillia, where humanoid aliens began making periodic visits and interacting with the local residents starting in 1956. The pictures were allegedly taken by two men who boarded the 24-meter (79-ft) spacecraft at the invitation of one of the humanlike ETs, who wore sunglasses as he (it appears to be a he) showed them around the 10-meter (31-ft) cabin and allowed a picture of him wearing sunglasses to protect his eyes. Pinotti claims the photos first appeared in 1958 in a book called “Sono Extraterrestri” by Alberto Perego and have never been seen outside of Italy.

Some ufology experts will recognize this story as the so-called “Friendship case,” a decades-long series of alien encounters in and around Pescara, Italy, from 1956 through the 1970s that was covered in a 2009 documentary, “The Friendship Case,” which contained photographs (although apparently not the ones in the book) and interviews with some of the alleged hundreds of witnesses, many of whom were said to belong to Italian high society and some in government positions.

It appears that Dr. Pinotti is promoting the release of “UFO Contacts In Italy: Volume One : 1907 – 1978” to various media outlets and they have picked up on this particular story and its grainy photo of an alleged alien. However, the rest of the book looks like it will be pretty interesting and promises at least a second volume with additional sightings from 1978 to the present.

It may not be time to believe just yet, but it’s definitely time to read.

The Falcon Heavy is essentially three of SpaceX's workhorse Falcon 9 vehicles strapped together.

But the triple-booster configuration has demanded a number of specific alterations, including a strengthening of the central core booster.

The 27 Merlin engines at the base of the rocket should be capable of generating almost 23,000 kilonewtons of thrust - slightly more than double that of the world's current most powerful rocket, the Delta IV Heavy, which is operated by US competitor United Launch Alliance.

Several strange phenomena have led some to believe that the eternal companion of the Earth; the Moon is, in fact, some sort of a huge spaceship. Crazy theory? Well, here’s why.

A curious video taken from a backyard telescope, which showed an alleged UFO fleet over the moon, caused a stir worldwide. This makes us wonder about what could possibly hide in that celestial body. Is it possible that there are civilizations living there if so what is their purpose? and what is its real origin of the moon?

Those who believe in the Alien Moon theory state that the moon had to be created by a highly developed civilization, much more than ours. Under this unusual logic, our artificial satellite would have to be hollow inside so that, within it, the aliens could place fuel for machinery, materials and accessories that would be used to repair working instruments, navigational instruments, observation equipment and all kinds of machinery, but most importantly, it could actually be used as a gigantic underground base or even as a giant spaceship.

If to all of the above we add the fact that there are some astronauts, those who went on NASA’s missions such as the “Apollo”,the now retired astronauts, have publicly said they have had contact with UFO’s and aliens, and that are even extraterrestrial beings living there having that said, for some, this does not sound so crazy after all.

Google Moon Photographs used in the Sea of Muscovy ( were several mysteries have been spotted) come from the Japanese probe Kaguya, also known as SELENE (selenological and Engineering Explorer), which for nearly two years was analyzing various aspects of our satellite, the distribution of elements on its surface, the magnetic and gravitational field, etc. The interest in this particular area is very big, ugolofists claim that this specifica area is very attractive when looking for anomalies thus it is a very interesting part of the moon that holds the answer for several questions that have been postulated throughout the years.

Recently triangular objects have been spotted on the surface of the moon, leading ufologists to speculate about the purpose of the odd objects but sceptics argue that the mysterious objects are actually simple pixels that do not appear in the original image. In addition, they argue that if you look closely you can see a set of other points “scattered” by other areas of the Moon.

The answer to this is that Google stores multiple image frames in various resolutions, using filters that create noise  along the boundaries between light and dark regions, creating curios spots that some might interpret as out-of-place-objects. But the pixel theory does not explain geometrical patterns in these objects, if you take in count the pixelation theory, then you would expect the pixels to create random dots not connected, but the objects that have been identified on the moon follow specific geometrical patterns; like triangles and rectangles. Here are some interesting images that can debunk the pixel theory about the lunar bases/objects.

Science might one day provide conclusive evidence of alien beings on the moon, bases, vehicles etc. But the truth is all of us can only wonder and propose theories at this point. Skeptics that debunk the alien moon base theories do not have the slight idea what is going on up there, or why human beings have not traveled to the moon even though it is a point of interest for us not only because of its proximity but also because of the exploitable natural resources present on the moon.

The truth is that the mystery of UFO’s continues, reports of anomalies appear again and again and will probably continue to do so. We can only form our own opinion about these mysterious objects and their origin and purpose.

Scientists Explain What Would Happen If The Earth Was Really Flat

What Would Happen If The Earth Was Really Flat?

Despite the fact there is ample evidence by which we know our planet is in fact round, there are many people who argue against these facts.

The Flat Earth Society, for example, contends that our planet is, in fact, flat and that the images and videos made available through NASA, ESA, Roscosmos and other space agencies are the results of Computer Generated Images (CGI).

In fact, more than 2,300 years ago, ancient Greek philosophers and Geographers managed to calculate the circumference of our planet and conclude the Earth was round. Eratosthenes of Cyrene, a Greek mathematician, geographer, poet, astronomer, and music theorist, and the chief librarian at the Library of Alexandria calculated the circumference of the Earth.

Eratosthenes was visiting Syene (now Aswan), he observed a phenomenon that caught his attention: at midday, on the summer solstice, no vertical shadows were being cast down. This happened because the Sun was directly overhead.

Upon returning to his city, Alexandria, the mathematician tried to prove if the same thing happened there. He stuck a stick in the ground to see if, at noon, it generated shadows or not.

And of course, there was a shadow, of 7 degrees to be precise. The conclusion that Eratosthenes drew from this phenomenon was the right one: The Earth must be spherical.

Now, scientists from the Lamont-Doherty Earth Observatory, from Columbia University explain how a Flat Earth simply can’t exist.

Despite the fact there is evidence which proves our planet is round, many people claim it’s not, and that we live on a Flat Earth.

That’s great but… what would happen if the Earth was in fact FLAT?

The belief in a flat Earth refuses to disappear from the curious mind of ‘flat-earthers.’

However, and despite the beliefs of the Flat Earth Society, a revealing blog from the Lamont-Doherty Earth Observatory at Columbia University explains what would happen if our planet was flat.

First, a ‘flat Earth’ as the one that the Flat Earth Society defends may not have gravity. It is not clear how gravity would work or be created in such a world, says Lamont Doherty geophysicist James Davis.

This is a huge problem since gravity explains a wide range of terrestrial and cosmic observations.

The same measurable force that causes an apple to fall from a tree also causes the moon to orbit the Earth and all the planets orbit around the sun.

People who believe in a flat Earth assume that gravity acts directly, but there is no evidence to suggest that it works that way.

What we know about gravity indicates that it would pull toward the center of the disk that forms the so-called flat Earth.

That means that it would only pull down at a point in the center of the disk.

As it moved further and further away from the center, gravity would pull more and more horizontally.

This would have some strange impacts, such as sucking up all the water towards the center of the world and causing the trees and plants to grow diagonally, as they develop in the opposite direction to the pull of gravity.

The Sun

Then we have our mighty and beautiful Sun.

In the scientifically supported model of the solar system, the Earth revolves around the sun because the latter is much more massive and has more gravity.

However, the Earth does not move towards to the Sun because it travels in an orbit.

In other words, the sun’s gravity is not acting alone.

The planet is also traveling in a direction perpendicular to the gravitational pull of the star; if it were possible to deactivate that gravity, the Earth would shoot in a straight line and speed out of the solar system.

In contrast, the linear pulse and the sun’s gravity combined, result in a circular orbit around the sun.

The Flat Earth theory places our planet at the center of the universe but does not suggest that the Sun orbits the Earth.

On the contrary, the sun rotates on the upper side of the world like a carousel, emitting light and heat downwards like a desk lamp.

Without the linear and perpendicular impulse that helps generate an orbit, it is not clear what force would prevent the Sun and the Moon from hovering above the Earth, says Davis, instead of impacting it.

Satellites: A no go for a Flat Earth

Furthermore, if our planet was, in fact, flat, artificial satellites would probably not be possible.

How would you orbit a plane?

“There is a series of satellite missions that society depends on that simply would not work,” says Davis.

For this reason, he says: “I can not think how GPS would work on a flat Earth.”

If the Sun and Moon simply revolve around one side of a flat Earth, there is likely to be a procession of days and nights.

But it would not explain the seasons, the eclipses and many other phenomena.

The Sun should also, presumably, be smaller than Earth as to not burn up or crash into our planet or the Moon.

We know that the Sun is more than 100 times the diameter of the Earth.

Deep beneath our planet, the solid core of the Earth generates the magnetic field of the planet.

But on a flat planet, that would have to be replaced by something else.

Maybe a sheet of liquid metal.

That, however, would not rotate in a way that would create a magnetic field.

Without a magnetic field, charged particles from the sun would fry the planet.

This means we would not have an atmosphere, as it occurred on Mars after our neighboring planet lost its magnetic field, causing the air and oceans to escape into space.

Contrary to popular belief, and what is written all over the internet, it is a mistake to think that many societies and educated people believed in the theory of the flat Earth.

“With few extraordinary exceptions, no one educated in the history of Western civilization since the third century of our era believed that the Earth was flat,” noted historian Jeffrey Burton Russell in 1997.

“A round Earth appears at least since the VI century before Christ with Pythagoras, who was followed by Aristotle, Euclid, and Aristarchus, among others, observing that the earth was a sphere,” explained Davis.

Study Finds TRAPPIST-1 Star System Contains Two Potentially Habitable Planets

An extraordinary discovery has been made by scientists in the Trappist-1 solar system. Astronomers say that two of the planets orbiting the TRAPPIST-1 star may have ideal conditions for life as we know it to flourish on their surface.

Astronomers have identified that two exoplanets in the TRAPPIST-1 system are more likely to be habitable, according to the eccentricity of their orbits and the consequent tidal heating.

The TRAPPIST-1 system has been of great interest to planetary observers and scientists because it seems to contain seven planets that are approximately the size of Earth.

Amy Barr, a researcher from the Planetary Science Institute, and co-authors Vera Dobos and Laszlo L. Kiss have examined the implications of internal structures and tidal warming on these planets, in a study published in Astronomy & Astrophysics.

The TRAPPIST-1 system.

“Because the TRAPPIST-1 star is very old and dark, the surfaces of the planets have relatively cold temperatures according to planetary standards, ranging from 400 degrees Kelvin, which is colder than Venus, to 167 degrees Kelvin, which is colder than the poles of the Earth,” Barr said in a statement.

“The planets also orbit very close to the star, with orbital periods of a few days, since most of their orbits are eccentric, not entirely circular, these planets could experience tidal heating as well as the moons of Jupiter and Saturn.”

“Assuming that the planets are composed of water ice, rock and iron, we can determine how much of each element could be present, and how thick the different layers could be, because the masses and radii of the planets are not very well restricted, it shows the entire range of possible interior structures and interior compositions,” said Barr.

This graphic compares the distance of planets from the host star in the TRAPPIST-1 system and the solar system.

The team’s results have shown that improved estimates of the masses of each planet can help determine if each of the planets has a significant amount of water.

The planets studied are named by letter, planets b to h, in order of distance from the star.

The analyzes carried out by co-author Vera Dobos show that planets D and E are the most susceptible to being habitable due to their moderate surface temperature, moderate amounts of tidal heating and because their heat fluxes are low enough to avoid entering a state of greenhouse runaway.

An ocean of global water probably covers the TRAPPIST D.

The team calculated the balance between tidal warming and convective heat transport in the mantles of each planet.

The results show that planets b and c probably have partially melted rock layers.

The document also shows that planet C probably has a solid rock surface, and could have eruptions of silicate magmas on its surface driven by tidal warming, similar to Jupiter’s moon Io.

Alien wearing sunglasses to protect his eyes visited Earth in 1957, UFO expert claims

It was a fine October 1957 night in Francavilla on Italy's Adriatic coast - but something extraordinary of the otherworldly kind was about to happen. 

At least according to an aerospace expert and sociologist who claims an alien wearing dark shades to cover his eyes when it landed its UFO and let two villagers on board.

Dr Roberto Pinotti, 73, said the human-like beings actually visited often and even posed for pictures. They just wanted to be “friends,” he said.

And in a series of chilling but grainy pictures published in his new book, UFO Contacts In Italy, the author claims to reveal photos of the interior of an alien spacecraft and an extra-terrestrial being.

Picture: The alien let two people inside the UFO and even let them take photos, it is claimed

 (FLYING DISK PRESS)

The UFO was 24 metres in diameter and the control cabin was 10 meters, claims Dr Pinotti, who is also the founder of Italy’s National UFO Centre.

He said in a statement: 

These rare and extraordinary photographs, as well as two photographs of the alleged extraterrestrial pilot… have been published here for the first time.

He added that you can see inside the “cockpit with seating,control panel and other objects.”

Speaking to indy100, former director of investigations for the British UFO Association Philip Mantle said that we should keep an open mind but also remain sceptical about UFO claims like this. He said:

It is the easiest thing to do to shout 'fake' or 'hoax' without ever doing any investigation in the first place.

As I have not personally investigated these photos I therefore remain open mind although somewhat sceptical.

I believe the best way to get to the bottom of these photos is to get them into the public domain which is exactly what we have done.

Once you do that then others may come forward with more information that can either support the authenticity of such photos or offer evidence that shows them to be fake. 

Mr Mantle added that these photos are very unique as whether fake or real, they show the interior of a UFO. There are many photos that claim to show extraterrestrial spacecraft but not many from the inside.

Sun pillars, or light pillars, are shafts of light extending from the sun or other bright light source. They’re caused by ice crystals drifting in Earth’s air.

Canada geese look like ghosts as they fly though a sun pillar – January 28, 2017 – in Quakertown, Pennsylvania.

EarthSky Facebook friends occasionally post beautiful photos of sun pillars, or light pillars. For example, there was a beautiful one seen from the U.S. West Coast on March 20, 2016 … a beautiful prelude to the first full night of spring. Sun pillars are vertical shafts of light that extend upward (or downward) from a bright light source, such as the sun or other bright light low on the horizon. They can be five to 10 degrees tall and sometimes even higher. They might lengthen or brighten as you gaze at them.

They’re beautiful and wondrous. They’re also the source of some UFO reports!

Joe C. Tabb and Dawn Tabb caught this amazing sun pillar at sunset on May 10, 2016. A storm had recently passed.

Another shot of the beautiful sun pillar seen on March 20, 2016, from the U.S. West Coast. This one is from Chris Levitan Photography. Thanks, Chris!

Sun pillars or light pillars are formed by reflection from hexagonal plate-like ice crystals in Earth’s air. These crystals drift through the atmosphere with a horizontal orientation, gently rocking from side to side as they fall. Diagram via University of Illinois.

Sun pillars or light pillars form when sunlight (or another bright light source) reflects off the surfaces of millions of falling ice crystals associated with thin, high-level clouds, for example, cirrostratus clouds. The ice crystals have roughly horizontal faces. They are falling through Earth’s atmosphere, rocking slightly from side to side.

When is the best time to see a sun pillar or light pillar? 

µYou’ll most often see sun pillars when the sun is low in the western sky before sunset, or low in the east just after the breaking of dawn. You might even see a sun pillar when the sun is below the horizon. Light pillars can be seen at any time of night.

View larger. | Wesley Liikane in Severn Bridge, Ontario captured these light pillars on December 23, 2013. See more photos by Wesley at Cowboy with a Camera on Facebook.

They’re called sun pillars when the sun helps make them. But this the moon or even streetlights can create this light phenomenon, too, in which case the name light pillar is more appropriate.

These pillars of light often prompt people to report sightings of UFOs. They can sometimes look strange! There are said to be a lot of UFO reports caused by light pillars over Niagara Falls, where the mist from the rush of descending water interacts with the city’s many upward facing spotlights. Light pillars do appear frequently over Niagara Falls, especially during the winter.

As always, the great website Atmospheric Optics is a wonderful place to go and learn more about sun pillars.

Bottom line: Sun pillars, or light pillars, are vertical shafts of light that can sometimes be seen extending upwards or downwards from the sun or other bright light source. They’re caused by light reflection from hexagonal ice crystals drifting in Earth’s atmosphere.

Zhong Zhong and Hua Hua result from decades of trying to make somatic cell nuclear transfer work in monkeys

BY 

DAN GARISTO 

 

DOUBLE TROUBLE  Cloned macaque sisters Zhong Zhong and Hua Hua, the first primates successfully cloned via somatic cell nuclear transfer, are just 8 and 7 weeks old, respectively.

QIANG SUN, MU-MING POO/CHINESE ACADEMY OF SCIENCES

Meet Zhong Zhong and Hua Hua, the first primates cloned by reprogramming adult cells.

Two decades after Dolly the Sheep was successfully cloned(SN: 3/1/97, p. 132), Chinese researchers have used the same technique — somatic cell nuclear transfer — to clone two healthy baby macaque monkeys. The results, reported January 24 in Cell, could lead to more efficient cloning and a better way to study genetic diseases in primates.

“This could be it — the next step in cloning,” says Jose Cibelli, a geneticist at Michigan State University in East Lansing not involved with the study.

Over 20 species of mammals have been cloned via somatic cell nuclear transfer — including cats, dogs, rats and even a camel (SN: 3/23/02, p. 189). This cloning technology has improved since Dolly’s birth in 1996. Back then, she was the only sheep born from 277 attempts. By 2014, the cloning technique had an 80 percent success rate in pigs. Despite these gradual advances (SN: 3/8/14, p. 7), cloning of nonhuman primates has long eluded researchers.

A rhesus monkey “clone” was created through embryo splitting, a technique that divides a single embryo into genetically identical embryos, in 1999. But this type of cloning has little in common with somatic cell nuclear transfer.

In somatic cell nuclear transfer, a nucleus from a mature body cell is transplanted into an egg cell without a nucleus. The egg cell must then reprogram the nucleus’s DNA, basically stripping the body cell of its identity and returning it to an embryonic state. With no set identity, it can become any kind of cell in the body.  

TWICE THE FUN Zhong Zhong and Hua Hua, the first primates successfully cloned via somatic cell nuclear transfer, are healthy, playful and, so far, completely normal for baby macaques. The sisters will spend the next few months in an incubator together.

Previous failures in reprogramming primate cells probably happened because the egg ran into roadblocks — portions of the body cell’s DNA known as reprogramming-resistant regions, say study coauthor Mu-ming Poo, director of the Institute of Neuroscience at the Chinese Academy of Sciences in Shanghai, and his colleagues. In these regions, DNA is so tightly wrapped around proteins called histones that the egg can’t reprogram those bits. So the researchers added two molecules aimed at loosening the DNA’s packaging.

The team tried this method with two types of body cells: ovarian cells from an adult and connective tissue cells from a fetus. Although 22 out of 42 monkeys became pregnant with embryos cloned from ovarian cells, only two babies were born and neither survived long past birth. Efforts with embryos made with the fetal cells resulted in six pregnancies among 21 surrogate monkey moms and two healthy babies.

 “After 20 years of trying from the most talented groups, and nothing working, finally this works,” Cibelli says. “This research is going to help cloning of all species.”

Cloned primates could help researchers better understand diseases in humans. Macaques are close genetic relatives to humans, making the monkeys better analogs than other lab animals. And clones make it easier to weed out the complications of different genetics when studying diseases or testing drugs.

The sisters are just a few weeks old, but they hold a lifetime of promise for researchers. Poo says the scientists will watch for any abnormalities as Zhong Zhong and Hua Hua grow and play.

“The monkeys are in good health and very active,” he says. “There are no signs they are unhealthy.”

Unlike 3-D images of old, these high-res pictures are visible from almost any direction

BY 

MARIA TEMMING 

SCI-FI GRAPHICS GET REAL  A new laser system renders 3-D images in thin air, and could pave the way for futuristic displays akin to the iconic Princess Leia scene in Star Wars. Here, the system displays a researcher imitating the scene.

D.E. SMALLEY ET AL/NATURE 201

The 3-D displays seen in such sci-fi movies as Star Wars may not be so far, far away.

A new laser system renders full-color 3-D images in thin air, researchers report in the Jan. 25 Nature. This technology could someday make futuristic, free-floating visuals for everything from air traffic control to surgical planning.

With this new technology, “you really can, in principle, achieve what everyone hopes to achieve, which is the image of Princess Leia in that scene in Star Wars,” says Curtis Broadbent, a physicist at the University of Rochester in New York who was not involved in the work.

Whereas holograms are images on flat surfaces that only appear three-dimensional because of how the light bounces off the material, the newly created images actually take up 3-D space (SN: 12/4/10, p. 8). Two-dimensional images of virtual performers can also be made to appear 3-D through stage tricks that involve carefully placed projectors and reflective surfaces. But like holograms, these seemingly 3-D images can only be viewed from certain angles. The new technique creates 3-D images that can be seen from almost any direction.

Using a nearly invisible laser, researchers can steer a tiny glowing particle through a path in 3-D space to create images that can be seen from almost any angle. Here, the team draws a butterfly (left), a portrait of Princess Leia (middle) and a squiggle (right).

This system works by trapping a cellulose particle that’s mere micrometers across in a beam of nearly invisible laser light. That laser repeatedly moves the particle along a specific path through the air, for example, in the shape of a corkscrew or the outline of a butterfly. At each point on the particle’s path, other lasers illuminate it with red, green or blue light, which the particle scatters in all directions. This creates a single image pixel that can be viewed from all sides.

Because the particle whizzes through the air so quickly and loops through the same path over and over again, all these pixels blur together — like the tip of a sparkler waved so fast that it seemingly smears into a solid line. This creates what appears to be a still image floating in the air.

Daniel Smalley, an electrical engineer at Brigham Young University in Provo, Utah, and his colleagues used this method to produce graphics about the size of a postage stamp. Because the technology draws a picture with a single particle, the researchers could create only small images, including a high-resolution picture of Earth about one centimeter in diameter.

“Scaling that up to even something about the size of a computer monitor would be pretty challenging,” Broadbent says. Researchers would have to refine their prototype to make pictures using many particles.

Smalley says he is already imagining a system that manipulates 100 or even 1,000 particles at once. With those improvements, “the sky becomes the limit,” he says.

PARTICLE PAINTING Researchers created a one-centimeter-wide image of Earth (photographed hovering above a fingertip) by using a nearly invisible laser to drag a glowing 10-micrometer particle back and forth.

D.E. SMALLEY ET AL/NATURE 2018

Free-floating images could help doctors practice surgery before the patient goes under the knife, says physicist Barry Blundell, of the University of Derby in England, whose commentary appears in the same issue of Nature. This technology could also be used for physical therapy or improving athletic performance. People could record themselves performing various activities, like swinging a golf club, and then view the footage on 3-D displays to carefully study their bodily motion, explains Blundell. And if the images can be continually updated with real-time data, such 3-D visuals could provide air traffic controllers with dynamic maps of planes in the air, or help researchers track satellites to ensure they don’t collide.

The possibilities for advertising, education and entertainment systems are endless, Broadbent says. The world may someday be full of pop-up images like those imagined in the film Jurassic World, where museum patrons walk through a hall where a projected dinosaur image stands on display, or like the free-standing visuals used by the character Tony Stark in designing his metal suits in the Iron Man films. And unlike virtual reality systems, these new laser-drawn pictures can be seen with the naked eye: No headgear required. (SN: 3/18/17, p. 24)
