Looking For Signs of Extraterrestrial Life Just Got a Whole Lot Easier
There's a new test for alien habitability.
MATT WILLIAMS, UNIVERSE TODAY
When it comes to searching for worlds that could support extra-terrestrial life, scientists currently rely on the "low-hanging fruit" approach.
Since we only know of one set of conditions under which life can thrive – i.e. what we have here on Earth – it makes sense to look for worlds that have these same conditions. These include being located within a star's habitable zone, having a stable atmosphere, and being able to maintain liquid water on the surface.
Until now, scientists have relied on methods that make it very difficult to detect water vapour in the atmosphere's of terrestrial planets. But thanks to a new study led by Yuka Fujii of NASA's Goddard Institute for Space Studies (GISS), that may be about to change.
Using a new three-dimensional model that takes into account global circulation patterns, this study also indicates that habitable exoplanets may be more common than we thought.
In addition to Fujii, who is also a member of the Earth-Life Science Institute at the Tokyo Institute of Technology, the research team included Anthony D. Del Genio (GISS) and David S. Amundsen (GISS and Columbia University).
To put it simply, liquid water is essential to life as we know it. If a planet does not have a sufficiently warm atmosphere in order to maintain liquid water for a sufficient amount of time (on the order of billions of years), then it is unlikely that life will not be able to emerge and evolve.
If a planet is too distant from its star, its surface water will freeze; if it is too close, its surface water will evaporate and be lost to space.
While water has been detected in the atmospheres of exoplanets before, in all cases, the planets were massive gas giants that orbited very closely to their stars (AKA "Hot Jupiters"). As Fujii and his colleagues state in their study:
"Although H2O signatures have been detected in the atmospheres of hot Jupiters, detecting molecular signatures, including H2O, on temperate terrestrial planets is exceedingly challenging, because of the small planetary radius and the small scale height (due to the lower temperature and presumably larger mean molecular weight)."
When it comes to terrestrial (i.e. rocky) exoplanets, previous studies were forced to rely on one-dimensional models to calculate the presence of water.
This consisted of measuring hydrogen loss, where water vapour in the stratosphere is broken down into hydrogen and oxygen from exposure to ultraviolet radiation.
By measuring the rate at which hydrogen is lost to space, scientists would estimate the amount of liquid water still present on the surface.
However, as Fujii and his colleagues explain, such models rely on several assumptions that cannot be addressed, which include the global transport of heat and water vapour, as well as the effects of clouds.
Basically, previous models predicted that for water vapour to reach the stratosphere, long-term surface temperatures on these exoplanets would have to be more than 66°C (150°F) higher than what we experience here on Earth.
These temperatures could create powerful convective storms on the surface. However, these storms could not be the reason water reaches the stratosphere when it comes to slowly rotating planets entering a moist greenhouse state – where water vapour intensifies heat.
Planets that orbit closely to their parent stars are known to either have a slow rotation or to be tidally-locked with their planets, thus making convective storms unlikely.
This occurs quite often for terrestrial planets that are located around low-mass, ultra cool, M-type (red dwarf) stars. For these planets, their proximity to their host star means that it's gravitational influence will be strong enough to slow down or completely arrest their rotation.
When this occurs, thick clouds form on the dayside of the planet, protecting it from much of the star's light.
More From ScienceAlert
The team found that, while this could keep the dayside cool and prevent water vapour from rising, the amount of near-Infrared radiation (NIR) could provide enough heat to cause a planet to enter a moist greenhouse state.
This is especially true of M-type and other cool dwarf stars, which are known to produce more in the way of NIR. As this radiation warms the clouds, water vapour will rise into the stratosphere.
To address this, Fujii and his team relied on three-dimensional general circulation models (GCMs) which incorporate atmospheric circulation and climate heterogeneity.
For the sake of their model, the team started with a planet that had an Earth-like atmosphere and was entirely covered by oceans. This allowed the team to clearly see how variations in distance from different types of stars would effect conditions on the planets surfaces.
These assumptions allowed the team to clearly see how changing the orbital distance and type of stellar radiation affected the amount of water vapour in the stratosphere. As Fujii explained in a NASA press release:
"Using a model that more realistically simulates atmospheric conditions, we discovered a new process that controls the habitability of exoplanets and will guide us in identifying candidates for further study… We found an important role for the type of radiation a star emits and the effect it has on the atmospheric circulation of an exoplanet in making the moist greenhouse state."
In the end, the team's new model demonstrated that since low-mass star emit the bulk of their light at NIR wavelengths, a moist greenhouse state will result for planets orbiting closely to them.
This would result in conditions on their surfaces that comparable to what Earth experiences in the tropics, where conditions are hot and moist, instead of hot and dry.
What's more, their model indicated that NIR-driven processes increased moisture in the stratosphere gradually, to the point that exoplanets orbiting closer to their stars could remain habitable.
This new approach to assessing potential habitability will allow astronomers to simulate circulation of planetary atmospheres and the special features of that circulation, which is something one-dimensional models cannot do.
In the future, the team plans to assess how variations in planetary characteristics -such as gravity, size, atmospheric composition, and surface pressure – could affect water vapour circulation and habitability.
This will, along with their 3-dimensional model that takes planetary circulation patterns into account, allow astronomers to determine the potential habitability of distant planets with greater accuracy. As Anthony Del Genio indicated:
"As long as we know the temperature of the star, we can estimate whether planets close to their stars have the potential to be in the moist greenhouse state. Current technology will be pushed to the limit to detect small amounts of water vapour in an exoplanet's atmosphere. If there is enough water to be detected, it probably means that planet is in the moist greenhouse state."
Beyond offering astronomers a more comprehensive method for determining exoplanet habitability, this study is also good news for exoplanet-hunters hoping to find habitable planets around M-type stars.
Low-mass, ultra-cool, M-type stars are the most common star in the Universe, accounting for roughly 75 percent of all stars in the Milky Way. Knowing that they could support habitable exoplanets greatly increases the odds of find one.
In addition, this study is VERY good news given the recent spate of research that has cast serious doubt on the ability of M-type stars to host habitable planets.
This research was conducted in response to the many terrestrial planets that have been discovered around nearby red dwarfs in recent years.
What they revealed was that, in general, red dwarf stars experience too much flare and could strip their respective planets of their atmospheres.
These include the 7-planet TRAPPIST-1 system (three of which are located in the star's habitable zone) and the closest exoplanet to the Solar System, Proxima b.
The sheer number of Earth-like planets discovered around M-type stars, coupled with this class of star's natural longevity, has led many in the astrophysical community to venture that red dwarf stars might be the most likely place to find habitable exoplanets.
With this latest study, which indicates that these planets could be habitable after all, it would seem that the ball is effectively back in their court!
Manen van Mars kunnen weleens elektrisch geladen zijn
Manen van Mars kunnen weleens elektrisch geladen zijn
Caroline Kraaijvanger
En daar kunnen astronauten wel eens serieus hinder van ondervinden.
Verschillende ruimtevaartorganisaties en -bedrijven dromen van een bemande missie naar Mars. Maar ook de manen van Mars – Phobos en Deimos – lijken heel geschikte bestemmingen, onder meer vanwege hun zwakke zwaartekracht (die het gemakkelijker maakt om te landen). In de toekomst kunnen astronauten voet op deze manen zetten en vanaf het oppervlak van Phobos en/of Deimos robotische missies op Mars aansturen (zie kader).
Op dit moment worden robotische missies op Mars – denk aan de Marsrovers Opportunity en Curiosity – vanaf de aarde aangestuurd. Dat werkt prima, maar men moet altijd rekening houden met een vertraging: signalen doen er zo’n 20 minuten over om van de aarde naar Mars te reizen en een reactie laat dus 40 minuten op zich wachten. Aansturing vanaf Phobos of Deimos is een stuk aantrekkelijker, omdat die vertraging dan wegvalt.
Zonnewind Maar het lijkt erop dat we tijdens die bemande missies naar Phobos of Deimos wel serieus rekening moeten houden met de zonnewind. Nieuw onderzoek wijst namelijk uit dat deze ervoor kan zorgen dat gebieden op de manen elektrisch geladen worden. “Wij ontdekten dat astronauten of rovers significante elektrische ladingen kunnen verzamelen wanneer ze zich verplaatsen op de nachtzijde van Phobos (de zijde van de maan die tijdens de Martiaanse dag op Mars gericht is, red.),” zo vertelt onderzoeker William Farrell. “Hoewel we niet verwachten dat deze ladingen groot genoeg zijn om een astronaut te verwonden, zijn ze mogelijk wel groot genoeg om gevoelige apparatuur aan te tasten, dus moeten we ruimtepakken en apparatuur ontwikkelen die deze dreiging beperkt.”
Elektronen en ionen Farrell en collega’s trekken die conclusie nadat ze de impact die de zonnewind op Phobos heeft, bestudeerden. Phobos heeft geen atmosfeer en wordt dus direct aan de zonnewind blootgesteld. Die zonnewind bestaat uit negatief geladen elektronen – die licht zijn – en positief geladen ionen – die zwaar zijn. Normaal gesproken vinden we in de zonnewind net zoveel van deze lichte elektronen als zware ionen en is de zonnewind elektrisch neutraal. Maar eenmaal bij Phobos aangekomen, verandert dat. Phobos absorbeert de zonnewind namelijk alleen aan de dagzijde en hierdoor ontstaat aan de nachtzijde een leemte. Omdat de elektronen lichter zijn dan de ionen haasten zij zich naar die nachtzijde om die leegte te vullen. En zo wordt de nachtzijde van de maan elektrisch geladen (zie ook het filmpje hieronder).
Frictie Wanneer astronauten over die nachtzijde wandelen, kan die elektrische lading middels frictie tussen Phobos’ oppervlak en de ruimtepakken van de astronauten worden overgedragen. En gaandeweg kan zo een flinke elektrische lading ontstaan. Want het stof en gesteente op het oppervlak van Phobos geleidt slecht, dus de lading die astronauten opdoen, kunnen ze niet zo gemakkelijk weer afgeven. In sommige materialen, zoals de ruimtepakken die de Apollo-astronauten droegen, kan de lading gaandeweg oplopen tot zo’n 10.000 volt. Op het moment dat een astronaut iets aanraakt wat wél goed geleidt, kan die lading plots vrijkomen.
Hoewel het onderzoek zich beperkt tot maan Phobos gelden de resultaten waarschijnlijk ook voor Deimos. Ook deze maan heeft geen atmosfeer en wordt dus direct aan de zonnewind blootgesteld.
Nieuw bewijs dat er in de atmosfeer van de maan spannende dingen gebeuren.
De ijswolk bevindt zich boven de zuidpool van Titan op een hoogte van zo’n 160 tot 210 kilometer. Daarmee bevindt de wolk zich ver boven de regenwolken van Titan. De ijswolk is bovendien omvangrijk en beslaat een gebied tussen 75 en 85 graden zuiderbreedte.
Tegelijkertijd gecondenseerd Onderzoek wijst uit dat de wolk bestaat uit een combinatie van waterstofcyanide en benzeen. “Deze wolk vertegenwoordigt een nieuwe chemische formule voor ijs in Titans atmosfeer,” vertelt onderzoeker Carrie Anderson. “Wat interessant is, is dat dit giftige ijs bestaat uit twee moleculen die tegelijkertijd uit een rijke mix aan gassen gecondenseerd zijn.”
WIST JE DAT?
…er aanwijzingen zijn dat op Titan heftige regenstormen voorkomen? Tijdens die buien komt er geen water, maar vloeibaar methaan uit de lucht zetten. Soms wel 30 centimeter per dag!
Herfst Onderzoekers ontdekten de wolk dankzij Cassini. De sonde spotte de wolk drie keer tussen juli en november 2015. In die periode liep de herfst op Titan op zijn einde (seizoenen op de maan duren zeven aardse jaren).
Noordpool Eerder ontdekten onderzoekers ook al een ijswolk op het noordelijk halfrond van Titan. Deze wolk hing echter veel lager (onder de 150 kilometer) en had een heel andere samenstelling: waterstofcyanide en het complexe cyanoacetyleen.
Eén van de laatste foto’s die ruimtesonde Cassini naar de aarde stuurde laat Titan zien.

Titan is de grootste maan die Saturnus rijk is en de enige maan in ons zonnestelsel met een dichte atmosfeer en wolken. De atmosfeer van de maan bestaat voornamelijk uit stikstof en methaan. Onderzoek wijst uit dat in de atmosfeer van de maan allerlei chemische processen gaande zijn, waarbij soms ook heel complexe (organische) moleculen ontstaan.
'Mars heeft valleien te danken aan zomerse toptemperaturen'
'Mars heeft valleien te danken aan zomerse toptemperaturen'
Caroline Kraaijvanger
Onderzoek verklaart hoe op een jong Mars – waarop de gemiddelde temperatuur ver onder het vriespunt lag – toch water kon stromen.
Het is een mysterie. Op het oppervlak van Mars vinden we geologisch bewijs – bijvoorbeeld vier miljard jaar oude, door vloeistoffen uitgekerfde valleien – dat erop wijst dat de planeet ooit warm en nat was. Maar tegelijkertijd vertellen klimaatmodellen ons dat de gemiddelde temperatuur op het jonge Mars ver onder het vriespunt bleef. Hoe kunnen we die twee verhalen met elkaar verenigen? Hoe kan er ooit genoeg water over Mars hebben gestroomd om valleien uit te kerven, als de planeet ijzig koud was?
Antarctica In het blad Icarus komen onderzoekers met een mogelijke oplossing voor dat vraagstuk. Hun studie wijst erop dat Mars lang geleden inderdaad heel koud was, maar dat gedurende de zomer toch toptemperaturen werden behaald die ervoor zorgden dat de randen van gletsjers smeltten. Daarbij ontstonden kleine hoeveelheden smeltwater die – jaar na jaar – toch in staat waren om de valleien op de rode planeet vorm te geven. “We zien dit ook in de Droge Valleien van McMurdo op Antarctica, waar de seizoensgebonden verschillen in temperatuur voldoende zijn om meren te doen ontstaan en in stand te houden, ook al ligt de gemiddelde jaarlijkse temperatuur ver onder het vriespunt,” vertelt onderzoeker Ashley Palumbo.

Modellen De onderzoekers baseren hun conclusies onder meer op een geavanceerd klimaatmodel van het jonge Mars. Dit klimaatmodel gaat ervan uit dat de atmosfeer van Mars in een ver verleden – net zoals vandaag – voornamelijk uit koolstofdioxide bestond. Het model genereert een vrij koud en ijzig jong Mars, deels ook doordat de energieproductie van de zon in die tijd nog een stuk lager uitviel. De onderzoekers modelleerden Mars meerdere keren en pasten daarbij sommige variabelen aan: zo werd er geëxperimenteerd met een atmosfeer die verschillende diktes had (aangenomen wordt dat de atmosfeer van Mars in het verleden dikker was dan nu, maar hoe dik precies, blijft onduidelijk). Ook werd gespeeld met de mate van opwarming door toedoen van broeikasgassen en variaties in de baan en stand van de rotatie-as van Mars.
Zomerse temperaturen Uit het model rolde zo een aantal scenario’s waarbij ijs de gebieden nabij de locatie van valleien bedekte. En hoewel de gemiddelde jaarlijkse temperatuur in deze scenario’s ver onder het vriespunt bleef, bracht het model in de zuidelijk gelegen hooglanden wel zomerse toptemperaturen voort die boven het vriespunt uitkwamen. In die scenario’s was smeltwater dus verantwoordelijk voor de valleien.
Genoeg? Maar brachten al die scenario’s wel voldoende smeltwater voort om de valleien die we nu op Mars zien, uit te kerven? Een paar jaar geleden berekenden onderzoekers hoeveel water er minimaal nodig was om de grootste valleien uit te kerven. En die data gebruikten onderzoekers om te kijken welke gemodelleerde scenario’s konden verklaren wat we nu op Mars zien. Zo ontdekten ze dat het scenario waarin de baan van Mars zeer excentrisch was (afweek van een cirkelvorm) het beste paste. En zo’n zeer excentrische baan past keurig binnen het scala aan omloopbanen waarvan onderzoekers het aannemelijk achten dat Mars ze in het verleden kan hebben gevolgd.
“Deze studie voegt een plausibele hypothese toe die verklaart hoe vloeibaar water op het jonge Mars kan zijn ontstaan,” denkt onderzoeker Jim Head. Hij sluit echter niet uit dat het koude Mars ook op andere manieren nog aan vloeibaar water wist te komen. “We verkennen momenteel andere potentiële mechanismen die de planeet kunnen hebben verwarmd, waaronder vulkanisme en inslagen die ook kunnen hebben bijgedragen aan smelt op een koud en ijzig jong Mars.”
Wetenschappers hebben een gigantische grot op de maan ontdekt. De lavatunnel is namelijk zestig kilometer lang, honderd meter breed en ligt tientallen tot honderden meters onder het maanoppervlak.
Op het oppervlak is een gat met een doorsnee van vijftig meter zichtbaar. Dit gat – met de naam Marius Hills Skylight – is al langer bekend bij astronomen. Japanse astronomen hebben radargegevens geanalyseerd van het ruimtevaartuig SELENE. SELENE ontdekte een vreemd echo-patroon bij het maangat. De onderzoekers concluderen dat de echo het bewijs is van een lange lavatunnel.
Lavatunnels Lavatunnels ontstaan door vulkaanuitbarstingen. Lava baant zich via de tunnels een weg. Terwijl de lava door de tunnels stroomt, koelt de buitenste rand lava af en vormt een soort leiding in de tunnel. Wanneer de eruptie voorbij is en de lava niet langer door de tunnel stroomt, blijft een holle tunnel over.
Voorbeeld van een stad (Philadelphia) in een lavatunnel.
Stevig De lavatunnels op de maan zijn mogelijk bolvormig en stabiel tot een grootte van 5000 meter. “Dat zou op aarde niet kunnen, maar de zwaartekracht op de maan is veel lager en het gesteente daar hoeft niet dezelfde erosie te doorstaan,” vertelde onderzoeker David Blair in 2015. “In theorie zijn enorme lavatunnels op de maan – groot genoeg om een stad te herbergen – dus stevig.”
De ideale huisvesting Op de maan zijn ontzettend veel kuilen en lavatunnels. “Het is de perfecte plek om een maanbasis te bouwen, omdat de sommige kuilen deels overkapt zijn en wellicht toegang bieden tot ondergrondse grotten”, vertelt Robert Wagner van de staatsuniversiteit van Arizona. “Onder een afkapping of in een grot is er geen straling en worden astronauten niet bekogeld door micrometeorieten. Daarnaast is het er mogelijk niet stoffig en verschillen de temperaturen tussen dag en nacht minder dan boven het oppervlak.”
The search for alien life is set to be streamlined, helping astronomers narrow down potential candidates of alien worlds suspected to possibly support life, thanks to new research from Nasa. Scientists used a model that "realistically simulated atmospheric conditions" that would be required to support extraterrestrial life. The model aided the discovery of a completely new process that can boost the search for alien planets supporting life.
"Using a model that more realistically simulates atmospheric conditions, we discovered a new process that controls the habitability of exoplanets and that will guide us in identifying candidates for further study," Yuka Fujii of Nasa's Goddard Institute for Space Studies (GISS) and the Earth-Life Science Institute at the Tokyo Institute of Technology, who is also the lead author of the research paper, said in a statement.
What would an alien planet need to support life?
According to Nasa, liquid water is "necessary for life as we know it". To be considered habitable, an alien planet, for instance an exoplanet, would have to have a temperature that would allow liquid water to have existed on the planet's surface for roughly billions of years – enough time for life to have thrived.
However, the exoplanet's distance from its parent star can help determine if it could be habitable. For instance, if the exoplanet is too far away from its parent star, it would be too cold, freezing the planet's oceans. Alternatively, if the exoplanet is too close, the intense light from the parent star would eventually cause the oceans to evaporate and be lost to space.
"This happens when water vapour rises to a layer in the upper atmosphere called the stratosphere and gets broken into its elemental components (hydrogen and oxygen) by ultraviolet light from the star. The extremely light hydrogen atoms can then escape to space. Planets in the process of losing their oceans this way are said to have entered a "moist greenhouse" state because of their humid stratospheres," Nasa said.
"We found an important role for the type of radiation a star emits and the effect it has on the atmospheric circulation of an exoplanet in making the moist greenhouse state," said Fujii. In case of exoplanets orbiting close to their parent stars, the power of the star's gravity will slow the planet's rotation, which in turn could lead to the planet becoming tidally locked. This is essentially when one side of the exoplanet will always face the star, giving that region constant daylight and the other region will always be away from the star, in a state of eternal night.
Such a scenario could lead to the cloud on the planet's day-side to act as an umbrella, keeping the planet cool and preventing water vapour from rising. The scientists found the NIR (near-infrared radiation), which is a type of light invisible to the human eye, that comes from a star could "provide the heat needed to cause a planet to enter the moist greenhouse state".

The new model showed that since these parent stars emit the bulk of their light at NIR wavelengths, this could result in a moist greenhouse state providing conditions similar or even warmer than those experienced in the Earth's tropics.
"For exoplanets closer to their stars, the team found that the NIR-driven process increased moisture in the stratosphere gradually. So, it's possible, contrary to old model predictions, that an exoplanet closer to its parent star could remain habitable," Nasa said.
"As long as we know the temperature of the star, we can estimate whether planets close to their stars have the potential to be in the moist greenhouse state," said Anthony Del Genio of GISS, a co-author of the paper. "Current technology will be pushed to the limit to detect small amounts of water vapour in an exoplanet's atmosphere. If there is enough water to be detected, it probably means that planet is in the moist greenhouse state."
The new study is based on scientists' assumptions of an Earth-like planet, but one covered in oceans. The assumptions allowed researchers to determine how variations in orbital distance and type of stellar radiation could affect the amount of water vapour in the atmosphere.
The team plans on modifying planetary characteristics such as size, gravity, atmospheric composition and surface pressure to see how they affect the circulation of water vapour and habitability, thereby helping narrow down the search for alien life.
No new large planet on the outskirts of our solar system has yet been discovered, although evidence is building, astronomers say. By the way, if Planet 9 does exist … it’s definitely not headed our way.
Artist’s concept of an unknown large planet, far from its sun, via NASA.
There’s been a fair amount of Planet 9 buzz this month, which seems to have kicked off with a feature story about this as-yet-undiscovered world at a NASA website on October 4. That story was duplicated multiple times online, and in the process it was altered in various good and bad ways, like the proverbial message in the telephone game. In at least one place, we saw a headline suggesting NASA admits the mysterious Planet 9 is real. NASA has done no such thing, of course, and such are the headlines that give us editors reputations as wanton purveyors of click bait. Then today (October 17, 2017), a University of Michigan doctoral student held a press conference to announce two pieces of evidence that may support the existence of a Planet 9. That news should stir the pot still more.
All this, and no large Planet 9 has been discovered.
Plus some of the buzz will likely become fuel for the Nibiru conspiracy theory, which (come to think of it) was supposed to culminate a month ago with a large planet colliding with Earth. And that’s enough said about that.
Astronomers announced in 2016 that a Planet 9 might exist. Their theory was based on the way some trans-Neptunian objects behave. These are rocky objects smaller than Pluto that orbit the sun at a greater average distance than Neptune. It seems the orbits of the most distant ones – those whose average distance from the sun is more than 250 times as far as Earth’s distance — point in the same direction.
Could a large Planet 9 be pulling on them?

The new research announced on October 17 works with the orbits of trans-Neptunian objects, too. It’s led by Juliette Becker, a graduate student in the Department of Astronomy at University of Michigan. Becker’s work consists of a large set of computer simulations, which, the researchers say, uncovered two findings about trans-Neptunian objects, also known as TNOs. Their statement explained:
First, the researchers established a version of Planet 9 that would most likely cause our solar system to look the way it currently does, by preventing the TNOs from being destroyed or thrown out of the solar system.
Second, the simulations predict that there is a process that they call resonance hopping by which a TNO jumps between stable orbits. This process can prevent the TNOs from being ejected from the solar system.
Juliette Becker led computer simulations supporting the theory that our solar system might contain a large, distant, undiscovered planet.
The researchers conducted various simulations, and, in each one, they tested different versions of Planet 9 to see whether that version of the planet, with its gravitational forces, resulted in the same version of the solar system we see today. Becker said:
From that set of simulations, we found out that there are preferred versions of Planet 9 that make the TNO stay stable for longer, so it basically increases the probability that our solar system exists the way it does.
The ultimate goal would be to directly see Planet 9 — to take a telescope, point it at the sky, and see reflected light from the sun bouncing off of Planet 9.
Since we haven’t yet been able to find it, despite many people looking, we’re stuck with these kinds of indirect methods.

In the meantime, going back to the buzz, NASA’s October 4 Planet 9 feature story (called The Super-Earth That Came Home for Dinner) features a quote from one of the hypothetical planet’s most dedicated trackers, Konstantin Batygin, a planetary astrophysicist at Caltech in Pasadena, California, who said:
There are now five different lines of observational evidence pointing to the existence of Planet 9. If you were to remove this explanation and imagine Planet 9 does not exist, then you generate more problems than you solve. All of a sudden, you have five different puzzles, and you must come up with five different theories to explain them.
… it is now harder to imagine our solar system without a Planet 9 than with one.
That’s all logical and good. So … are we on the verge of discovering another large planet on the outskirts of our solar system? Maybe. Astronomers discover new things, both in our solar system and beyond, all the time. As always, stay tuned, and try to read past the headlines.
Bottom line: Although no Planet 9 has yet been discovered by astronomers, there’s continuing evidence one might exist. If such a world does exist, it’s approximately 20 times farther from the sun than the outermost large planet currently known, Neptune. It’s not heading our way.

How will the people who make the trip cope with the mental and physical rigors of the journey? Marc Jurblum, a training psychiatrist at the University of Melbourne and member of the Australasian Society of Aerospace Medicine’s Space Life Sciences Committee, outlined six of the key health issues facing prospective space travelers.

1. Space sickness
On Earth, tiny gyroscopes in your brain give you spatial awareness. They tell you when you tilt your head, accelerate, or change position. But it’s different in space. Jurblum said:
In Zero G, those don’t work as well and, as a result, astronauts suffer a lot of nausea. A lot of them spend days feeling incredibly unwell. It’s like being seasick.
There are many examples. In 1968, NASA launched Apollo 8. Astronaut Frank Borman suffered such a bad bout of space sickness on the way to the moon that Mission Control considered shortening the mission.
Fortunately, just like people going to sea eventually get their sea legs, astronauts develop ‘space legs’ within about two weeks. But once they return to Earth, the opposite is true — many of them have to work hard to get their ‘Earth legs’ back.

2. Mental stress
Space travel is still inherently dangerous. Essentially you are floating through an airless vacuum in a sealed-up container, only staying alive because of the machinery recycling your air and water. There is little room to move and you’re in constant danger from radiation and micro-meteorites. Jurblum said:
We don’t know what months and months of living in an unchanging capsule habitat with only blackness outside the little window will do to people’s minds. Even if you turn the ship around, Earth will be a distant speck of light. There’s little more than hydrogen atoms for hundreds of thousands of kilometers around you.
Research groups are looking at how to maintain mental health in extreme environments, including using interventions such as meditation and the positive impact pictures of nature can have on space travelers. Virtual Reality might also help by giving the astronauts a rest from the monotony.
Then there’s the issue of emotions. On Earth, if people get upset with their boss or workmate they might take out their frustrations at home or the gym. In space, astronauts can’t afford to get angry with each other. They must be able to react really quickly, communicate, and work as a team.
In contrast, there’s a positive psychological phenomenon of space travel, known as the “overview effect.” Jurblum said:
Most astronauts who have gone into space have come back with a change of perspective. They become more environmentalist, spiritual, or religious.
NASA astronaut Ron Garan described it as
…the realization that we are all traveling together on the planet and that if we all looked at the world from that perspective we would see that nothing is impossible.

3. Weaker muscles
There is no gravity on the International Space Station (ISS), and Mars only has about a third of Earth’s gravity. This plays havoc with the human body, Jurblum said. Our muscles are so used to fighting gravity on Earth that its absence means they weaken and waste.
Astronauts must do two to three hours of exercise every day just to maintain muscle mass and cardiovascular fitness. The heart loses muscle which would be extremely dangerous if they didn’t maintain it through exercise.
Tight, elastic body suits or “penguin suits,” developed by the Soviet space program, attempt to mimic the effects of gravity on muscles by providing a deep compression force on the skin, muscle, and bone—meaning they have to work harder to perform normal movements. But they’re far from perfect, Jurblum says.
4. Eye problems
A common hazard on the ISS is the fine specks that float around the cabin, often lodging in the eyes of astronauts and causing abrasions. But the lack of gravity and the movement of fluids are what can cause the most serious issues for astronauts, said Jublum.
Most end up wearing glasses in space and when they come back, some even have permanent changes to their vision.
The deterioration results from the fluid shift to the head building up in the skull where it bulges into the back of the eyeball and changes the shape of the lens. Jurblum said:
This bulging seems to cause the irreversible vision problems we’re trying to understand and manage.

5. Coughs and colds
If you catch a cold on Earth, you stay home and it’s no big deal. Space is another story. You’re living a densely packed, confined space—breathing recirculated air, touching common surfaces over and over again, with a lot less opportunity to wash.
The human immune system doesn’t work as well in space, so mission members are isolated for a few weeks before lift-off to guard against illness. Jurblum said:
We’re not sure why, but it seems that bacteria are more dangerous in space. On top of that, if you sneeze in space, all the droplets come straight out and keep going. If someone has a flu, everyone is going to get it and there are limited medical facilities and a very long way to the nearest hospital.

6. Medical emergencies
Luckily, there have not yet been any major medical emergencies in space, but astronauts have training to deal with them.
For instance, ISS astronauts have developed a way to perform CPR in zero gravity by bracing their legs on the ceiling while pushing down on the patient on the floor below.
While a rescue from the ISS can be performed within a day, the people who go to Mars will be an eight-month journey away, and they need to be prepared to manage on their own, Jurblum said:
How do you lift them on a stretcher, get them into an airlock, out of their suit, and onto a surgical table with a doctor, a botanist, and a couple of scientists to help do surgery? You may have an orthopedic surgeon on Earth sending you information on how to do it, but there is a 20-minute time delay.
Here on Earth, Mars Analogs simulate some of the conditions human beings could experience during a future mission to Mars, allowing researchers to work on solutions to situations like what to do if a team member breaks their leg while outside the base.
NASA is developing the capabilities needed to send humans to an asteroid by 2025 and Mars in the 2030s – goals outlined in the bipartisan NASA Authorization Act of 2010 and in the U.S. National Space Policy, also issued in 2010. Read more about NASA’s plans for a journey to Mars via NASA.

ATLANTA — Blue Origin announced Oct. 19 that it conducted the first successful test of its BE-4 engine, a major milestone for both the company's launch vehicle plans as well as for United Launch Alliance.
Blue Origin, in a tweet, said its first hotfire test of the BE-4 engine was a success. The company included a six-second video, taken from several angles, of the engine firing on a test stand, but provided no other information, including the date, duration or thrust level of the test. A Blue Origin spokesperson said the company was not releasing additional information about the test at this time.
"First hotfire of our BE-4 engine is a success," tweeted company founder Jeff Bezos. "Huge kudos to the whole @BlueOrigin team for this important step!"
The BE-4 is an engine that uses liquid oxygen and liquefied natural gas propellants and is capable of generating 550,000 pounds-force of thrust. The engine was developed in-house at Blue Origin primarily with its own funding, with some support from ULA.
Blue Origin plans to use the BE-4 on its New Glenn vehicle that the company announced last year. The first stage of the rocket will use seven BE-4 engines, with the second stage using a single BE-4. That rocket will be able to place up to 45 tons into low Earth orbit and 13 tons into geostationary transfer orbit.
The BE-4 is also under consideration by ULA for its next-generation Vulcan rocket. ULA is considering both the BE-4 and the AR1, a liquid oxygen and kerosene engine under development by Aerojet Rocketdyne, but has indicated that its preference is for the BE-4.
In an April interview, ULA Chief Executive Tory Bruno said that it was waiting for the outcome of an initial series of hotfire tests before formally selecting the BE-4. "The economic factors are largely in place now and the thing that is outstanding is the technical risk," he said then. "That's why we keep talking about the engine firing."
ULA spokesperson Jessica Rye said the company congratulated Blue Origin on the successful test, but gave no indication of when ULA might make a decision on the engine for Vulcan.
"Congratulations to the entire Blue Origin team on the successful hotfire of a full-scale BE-4 engine," she said in an Oct. 19 email. "This is a tremendous accomplishment in the development of a new engine."
At the time of the April interview, Blue Origin was expected to begin BE-4 engine tests in the coming weeks. However, in May the company reported it lost a set of powerpack hardware, a key component of the engine, during a test. At the time the company said it would be back in testing "soon" but offered few updates prior to the announcement of this test.
An independent assessment, conducted by NASA personnel and briefed to congressional staffers in June, concluded that the BE-4 retained a development lead of as much as two years over the AR1 despite the mishap. That briefing took place around the same time Blue Origin announced it will construct a factory in Huntsville, Alabama, to build BE-4 engines for both its own vehicles and for ULA, if it does select the BE-4 for Vulcan.

Global wave of animal mutilation defies any explanation
Global wave of animal mutilation defies any explanation
Just as there are reports of people disappearing – and being abducted by extraterrestrials – another phenomenon has caused a great debate among experts around the world: animal mutilations. The declassified records of the Federal Bureau of Investigation revealed that the FBI investigated MILES of cases of mutilation of cattle in the United States since at least the seventies, but with no result.
Just as there are reports of people disappearing – and being abducted by extraterrestrials – another phenomenon has caused a great debate among experts around the world: animal mutilations. The declassified records of the Federal Bureau of Investigation revealed that the FBI investigated MILES of cases of mutilation of cattle in the United States since at least the seventies, but with no result.
Early reports of mutilated cattle first appeared in the United States in the 1960s, when the states of Pennsylvania and Kansas were largely confined. The phenomenon was still largely unknown outside the livestock breeding communities until 1967 when Pueblo Cacique in Pueblo, Colorado published a story about a horse named Lady was mutilated under mysterious circumstances.
Shortly after, the press collected the story in general and was distributed throughout the country; this case was also the first characteristic of the speculation that the extraterrestrial beings and the unidentified flying objects were somehow related to the mutilation.
From the time the allegations of alleged animal mutilation began, the causes have been attributed in particular to natural decomposition, natural predators, cryptic predators, extraterrestrials, reserved government or armed forces and sects. Mutilations have been the subject of two independent federal investigations.
But in spite of this fact, the leading experts are also not sure and the more we look at this, the less it seems we understand. Skeptics argue that aliens are not involved, but that the defacement of livestock is in fact the product of natural disasters, sadistic jokes or other ‘sick’ jokes. But UFO investigators argue that the explanations of another world can not be nullified due to the fact that almost all attackers are carried out with surgical precision.
Mutilated cattle are found all over the world, but especially in US states. UU. Like South Dakota, Colorado, Kansas and Nevada, where farmers discovered the organs of their livestock: eyes, noses, hearts, livers, years and genitals. -removed with precision similar to a laser.
In addition, FBI documents clearly state that the best investigative minds in the United States can not answer the most frequent question of all: Who would be doing this?
An explanation of another world seems very likely according to many authors.
This is mainly because residents have reported seeing mysterious crafts as well as a strange light that has sinned in the sky circling the areas where later mutilated cattle appeared.
Chuck Zukowski, curator of UfoNut.com and a researcher who has been investigating cattle mutilations for decades, said in an interview with Sputink:
‘There are no signs of downing predators, there are no signs of the mass amount of hemorrhages and there are no signs of animal fighting, none! The animal has just been repositioned and, in some cases, a round depression is created while returning the animal. Mutilations have been going on for centuries: Native Americans also have stories of mutilated animals that occurred before Europeans migrated to North America, ‘Zukowski told Sputnik.
Although the exact nature of the mutilation varies from case to case, typical mutilation may involve some or all of the following characteristics:
Excision of the eyes, udders, and sexual organs.
Extraction of the anus to a depth of about 12 inches.
The cleavage of the tongue and lips.
The removal of one of the ears.
Removing the soft organs from the lower body.
The presence of incisions and cuts throughout the body that appear to have been made by a surgical instrument.
Inexplicable damage to the remaining organs, but no sign of damage in surrounding areas
Lack of signs of predation (scratches, teeth marks, traces of the predator) on or around the corpse.
Image captionA UK-commissioned report suggests AI could add £630bn to the economy within two decades
If my email inbox is anything to go by, a technology revolution is under way that is going to transform all of our lives very soon and it is called artificial intelligence.
A Welsh company is using AI to detect North Korean bio-weapons.
I could pop over to California to hear about "AI wearable solutions for aging population".
And Lloyd's of London has unveiled an artificial intelligence partnership with a firm that promises "in a decade a significant part of the insurance industry will be powered by AI".
These represent just three of the innumerable AI press releases aimed at me and other technology journalists over recent days.
Last week also saw the London premiere of AlphaGo, an excellent and surprisingly touching documentary about one of the great recent triumphs of artificial intelligence, Google DeepMind's victory over the champion Go player Lee Sedol.
Image copyrightMOXIE PICTURES Image captionGoogle DeepMind's defeat of a champion Go player has been made into a documentary
And then, over the weekend, as if to confirm this is a subject that should occupy politicians and policymakers as well as journalists, a major report on what the UK should be doing to nurture AI was published.
It was commissioned by the government and authored by two distinguished computer scientists, Prof Dame Wendy Hall and Dr Jerome Pesenti.
They say the UK is already well placed as a centre of artificial intelligence, and the government should act to cement its position.
Their recommendations include:
more investment in academic research
developing more skills throughout industry and the education sector
throwing open more datasets for AI scientists to work with
encouraging the uptake of AI techniques by all kinds of companies
All of these ideas seem eminently sensible and uncontroversial. But they are also predicated on a belief that this is urgent - that we are making very rapid progress, not just in developing artificial intelligence but in applying it in areas that will transform the economy.
It certainly appears to be the case that rapid advances in processing power, coupled with access to vast amounts of data and smart new algorithms are helping computers carry out all sorts of tasks once restricted to humans. But so far the impact on everything from jobs to the way industries such as healthcare and transport work appears minimal.
So, is there a danger that AI is being overhyped?
Let's dissect a few of the bold statements in that government AI report:
"We are at the threshold of an era when much of our productivity and prosperity will be derived from the systems and machines we create."
Well, it has always been the case that the machines we create - from the wheel, to the spinning jenny, to the dishwasher - drive increases in productivity and prosperity.
Are we clear that the AI revolution will deliver the kind of boost to living standards we saw in the 1950s and 1960s as mass production and the use of consumer goods took off?
"We are accustomed now to technology developing fast, but that pace will increase and AI will drive much of that acceleration."
First, you can question how fast technology has developed in recent years. Yes, we have computers that can differentiate between a cat and a dog and understand any language, but our physical infrastructure is not being rapidly transformed.
Indeed, when it comes to air travel or building new railways, you could argue that we are going backwards. Software is racing ahead, hardware not so much - just watch robots trying to play football if you are worried about them threatening to replace us.
So saying that the pace of change will increase, driven by AI, may be little more than a leap of faith.
"[Accenture] estimated that AI could add an additional $814bn (£630bn) to the UK economy by 2035, increasing the annual growth rate of GVA from 2.5 to 3.9%."
GVA - gross value added - is close to gross domestic product (GDP), the headline measure of a country's economic activity, including all the services and goods produced in a year.
Suggesting that its trend growth rate could rise to 3.9% - more than during boom decades the 1950s and 1960s - is, in the words of an economist of my acquaintance, "staggering". All the more so when you look at the UK's recent record, which has seen productivity growth flat-lining.
Now, big advances in technology can take time to show up in productivity growth - it took decades for factory owners to reorganise production around electric rather than steam power.
So, maybe we will see law firms become more efficient as AI lawyers assess contracts for risk, hospitals cut waiting lists as robot doctors examine scans, and cities cut congestion as autonomous cars and buses waft us from home to work.
Image copyrightGETTY IMAGES µImage captionCar manufacturers are investing deeply in self-drive AI systems
All of these advances are already technically possible - but you have to be quite an optimist to believe that the changes in our infrastructure, regulation and social attitudes needed to make them a reality will happen quickly.
Last week a House of Lords select committee on artificial intelligence heard evidence from three leading scientists, including Prof Hall.
They spoke of the UK's potential as a centre of AI excellence, and the urgent need for government to start thinking about both the benefits and the risks of the technology.
Then, the committee heard from three journalists - including me. And their lordships seemed rather startled to find that, by contrast with the scientists, we were pretty sceptical about the speed of this revolution.
We were not convinced that driverless cars would be on our roads very soon, but that meant we were also more optimistic that the threat to jobs from the robots had been exaggerated.
One of the peers mentioned that quote about futurology - that we tend to overestimate the effect of a technology in the short run and underestimate it in the long run.
The scientists will no doubt be proved right about AI one day, but the cynical old journalist in me thinks we can afford to relax for a while yet.
In July 1947 Sheriff Jess Slaughter and Deputy Sheriff Charles Fogus were travelling together to pick up a prisoner when they heard on their police radio reports of a crashed aircraft.
The two men, who were travelling to Roswell, New Mexico, decided to investigate and stumbled across the scene of one of the most famous UFO incidents in history.
While the US military have long claimed the crashed object was merely a weather balloon, conspiracy theorists believe the site was the scene of at least one alien aircraft crash and the recovery of extraterrestrials.
In a new book, UFOs TODAY – 70 Years of Lies, Misinformation and Government Cover-Up, law enforcement officer Fogus reveals he saw a downed flying saucer and military personnel removing a number of alien bodies from the scene.
It is the first time his statement has been published.
Deputy Sheriff Charles H Fogus of Howard County has striking testimony(Image: Irena Scott)
In the interview he says he say a flying saucer crashed into the side of a river bed which was "100ft across".
Describing the scene he said: "When we got there, the land was covered with soldiers. They were hauling a big, a creature.
"The bodies must have been 5 feet tall.
"I saw the legs and feet on some of them. They looked like our feet.
"The skin was a brownish color…. Like they were in the sun too long.
"There were soldiers there….about 3 or 4 hundred of them.
"We seen them haul them (the bodies) out there, out of the canyon up to the trucks….puttin them on the tow trucks so they could haul them."
Charles Forgus said he saw alien bodies at the Roswell site(Image: Irena Scott)
He says after about 20 minutes they were told to leave the scene and so continued on their journey to collect the prisoner.

Asked what he thought of what he saw, he said: "The Great Father didn’t just make this planet…. He made all of them. He put beings on these planets just like he put us on this one. They’re smarter then we are.
"They can get from there to here, but we can’t get from here to there."
The Daily Mirror has been passed a transcript of an interview between Deputy Sheriff Fogus of Howard County, Texas, and Los Angeles private investigator Deanna Short by the book publisher Philip Mantle, a former Director of Investigations for the British UFO Research Association.
He said: "Deanna recorded the interview on video and later had a transcript done of the interview and completed her Agency report to verify facts at that time related to Charles Forgus and Sheriff Jess Slaughter - both of Howard County, Texas.
Scene of the Roswell incident as described by the former deputy(Image: Irena Scott)
"Both were there and were on an overlook to view the crash scene recovery by the Army.
"I should note that according to Deanna's daughter Mackenzie, Charles made a special effort to note to Deanna "not to believe what others will say - he and the Sheriff did witness the Roswell crash scene". They had heard about the crash on the police radio which enabled them to find the location.
"It is rare that anyone new adds anything to the Roswell event from an eye witness point of view.
"If you treat the Roswell UFO crash as a 'cold case' investigation then new testimony like this can be invaluable.
"It could confirm what other witnesses have previously said or it could be another potential witness that has been eliminated from the enquiry.
"So either way it is an invaluable piece of information. To have it on video as well is a real luxury. I remain open minded on this gentleman's testimony but we hope that by making it public that others might be able to assist us in our investigations.
"I dare say many of those that know far more than me about the Roswell Incident will write it off as it does not fit the known Roswell crash scenario.
"All I will say is that I am working to try and find any more information and I leave this ‘Roswell File’ open. If anyone reading this has any information concerning the Roswell Incident we urge them to get in touch."

The full transcript:
Questioner: What I’m trying to do is pierce together……
CF: I was working for the Sheriff of. I was a Deputy there for Sheriff Slaughter, was back in the 40s. We went to Roswell to pick up a prisoner. When we got there, the land was covered with soldiers. They were hauling a big, a creature. Hauling him away.
What I seen of him looked just like the one we see on television, with big eyes. There was a big round thing in the canyon. It was about 100 feet across. They put that on a truck and hauled it away. They wouldn’t let us get very close to it either. So we headed up to get the prisoner in Roswell and back to.
Q: So you were on your way from to Roswell to pick up a prisoner and you happened to be at that place……
CF: It already had crashed. They were taking them out. There were soldiers there….about 3 or 4 hundred of them. They wouldn’t let you get very close. They were keeping all the people away. People were coming out there.
Q: What did the saucer (we’ll call it) look like?
CF: It was a big round thing. Across the middle it was about 100 feet.
Q: Did you see any lights around it?
A local newspaper report detailing the Roswell incident in 1947(Image: Sipa)
CF: No, they went out when it banged into the wall in the creek. It was like a mountain on the side of the creek.
Q: Did you see any creatures: How many did you see?
CF: Yeh, I saw them. I think I seen about four (of them).
Q: Were they covered up?
CF: Mostly. I saw the legs and feet on some of them.
Q: What did the feet look like? Do you remember?
CF: They looked like our feet.
Q: Could you figure how tall they were? They were laying flat, Right?
CF: Yeh, There is one thing I do remember. The Great Father didn’t just make this planet…. He made all of them. He put beings on these planets just like he put us on this one. They’re smarter then we are. They can get from there to here, but we can’t get from here to there.
(Note:CF is rather deaf. He wears two hearing aid appliances in this ears, so he answers my questions as follows :)
Q: Why do you think they’re here then?
CF: I don’t know where they hauled them. They might have hauled them to the hospital or somewhere.
Q: How long were you and Sheriff Slaughter at that site after you arrived?
CF: About 30 Minutes?
Q: Did you tell anyone about it?
CF: The Army was there and military soldiers were there.

Q: Did they tell you not to say anything?
CF: No, they didn’t tell me nothing’. They wouldn’t let you get close to ‘em.
Q: Did they actually see you observing what was going on?
CF: Sure, they saw me lookin’ at them.
Q: And they didn’t tell you to not say anything…..
CF: No, They wouldn’t let us get close to them. We were about 10 away.
Q: You were that close?
CF: We might have been further away. I didn’t have glasses then, I could see pretty good.
Q: What was your official capacity then?
CF: I was a Deputy The County Seat was I was riding with the Sheriff when we went to get the prisoner.
He didn’t order nobody except me to go with him. The UFO was already down when we got there. We went and got the prisoner afterwards. We heard about it on the radio.
Q: What did you hear on the radio?
CF: That the thing had crashed.
Q: But they didn’t know what ‘the thing’ was?
CF: No. But you would think that when people hear something like this, it scares the heck out of them. This came out of the police radio. We were on the way through there (to pick up the prisoner) when we heard it on the police radio. It was a big distance from to Roswell...you can look on a map and see it.
Q: So let me ask you this. When you guys were driving down the road and you were listening to the police radio……
CF: Yeh.....
A sign marking the spot where the sighting happened(Image: Photonica)
Q: Do you remember what was said on the radio about whatever it was... Do you recall?
CF: All I remember is they said that a saucer crashed out there in the canyon.
Q: They actually said the word ‘saucer’?
CF: They can call it a saucer if they want to but there ain’t a big enough cup of coffee for that thing.
Q: How long do you think you were at the site?
CF: Probably about 20 minutes. We seen them haul them (the bodies) out there, out of the canyon up to the trucks….puttin them on the tow trucks so they could haul them.
Q: Did anyone try to get you to leave the scene.
CF: No….they told the Sheriff that we had to go. That was good enough for us….He’s the boss.
Q: When they were taking the beings, we'll call them beings, were the beings laying on the ground around the saucer?
There are questions about the suspected alien crash at Roswell(Image: Getty)
CF: Yeh, they were lifting them up with a crane that they had and picking them up and swinging them to put them on the truck. The bodies must have been 5 feet tall.
Q: Did you see the heads?
CF: Yeh….they were covered. They eyes looked like the ones we see on television and the pictures of them.
Q: What color was the skin?
CF: As much as I could tell….the skin was a brownish color…. Like they were in the sun too long.
Q: From the time it crashed until the time you got there, do you know how much time went by? From the time you heard it on the police radio until you got there?
CF: About two hours.
Q: Did you see any writing or engraving on the saucer?
CF: I wasn’t that close to it?
Deputy Sheriff Charles H Fogus pictured when he was still working(Image: Irena Scott)
Q: If you were say 12 feet away from the beings, how far were the beings away from the saucer. Were they thrown pretty far?
CF; We couldn’t see that well because of the trees. It was in a riverbank. It slammed into a river bank. I say them lifting one up with the crane.
Q: Did anyone else talk to you about what was going on?
CF: There were some solders, but I don’t think they were from the Air Force.
Q: Where do you think they were from then?
CF: I don’t know. They were wearing uniforms. I didn’t pay no attention cause I just wanted to go with the Sheriff to get the heck out of there before something happened.
Q: When you guys were in the car to go pick the guy up, did you discuss or talk about what you had seen with the Sheriff?
An image of an "alien" from a TV show about Roswell(Image: Image net)
CF: No. I didn’t know what they were and he didn’t either or where they came from or nothin.
Q: Did you see any blood on the bodies?
CF: I don’t know…. I guess they were dead.
Q: You’re 81 years old now. When and where were you born?
CF: I was born in I don’t know what city.
Q: You have been in the army?
CF: I sure have, before I became a Deputy Sheriff.
Q: So when this thing at Roswell happened, you were already out of the Army and were a Deputy Sheriff. That happened in 1947. Now it’s 1999. That was 52 years ago, Charlie. And you still remember it clearly?
The Deputy Sheriff gave his interview before he died(Image: Irena Scott)
CF: Yeh, pretty clear.
Q: Has anyone ever talked to you or asked you to talk about what happened...like to the Government, cause there’s a lot of research going on now because of the cover-up.
CF: There was one that came around, and I told him to shut up and not come around. I don’t know who they were. That was when I was Deputy Sheriff.
Q: When you saw the saucer, can you remember in your mind what it looked like. Can you draw it?
CF: No….you draw it?
(Note: Charlie had the interviewer draw because he broke his arm and can’t use it). He directed her to draw a circle (not an oval). Then he directed her to draw another circle with the circle. This was a drawing of the top of the saucer. Charlie was standing on top of the opposite side of the bank of the dry creek bed where the saucer had crashed.

Q: Were you standing above it?
CF: I was standing on the back side. The saucer hit the bank on this side of the creek and I was standing on the other side of the bank, at the top of the hill. I was looking down at the site.
Q: So you had a ‘bird’s eye view‘, that’s why you were able to see the top of it?
CF: I didn’t have a ‘bird’s eye, I’ve got my own eyes (he laughs)
(showing Charlie the drawing the interviewer says "if this is the top (of the saucer), how much higher were you?"
CF: Probably about 20 feet above it.
Q: So, that’s why you saw the top (of the saucer). And you say, that from here to here (across the top of the saucer - diameter) is about 100 feet.
CF: It was evenly round.
A new book - UFOs TODAY, 70 Years of Misinformation, Lies and Government Cover-Ups By Irena Scott PhD - details the incident(Image: Irena Scott)
Q: So it was absolutely round…. Not oval shaped and you were 20 feet above it, that’s why you saw the top. Did you see the fingers and hands?
CF: No, they were covered up. But I saw the head.
Q: But you said you saw the feet.
CF: Yeah, later on, when they were passing by I saw the feet. I could see them lifting it up with the crane. They wouldn’t let you close enough when they were puttin’ them into the truck. When they were liftin' them on the crane you could see them layin’ on that thing.
Q: You said the body was covered. Were the arms layin on the stomach under the cover?
CF: When the wind blew, the cover went back so you could see the face. The same way with the feet.
Astartling discovery in Germany has caused scientists to question historical records regarding the evolution of man. Researchers from the Natural History Museum in Mainz announced Friday that they excavated 9.7 million-year-old teeth fossils from the Rhine river. What makes this finding so remarkable is that these teeth appear to be potentially hominin and considerably older than similar specimens found in Africa — a mysterious possibility that could rewrite what we know about where early human life emerged.
In a preprint published by ResearchGate, a team of researchers led by Natural History Museum deputy director Herbert Lutz write that they found two teeth — an upper left canine and an upper right first molar — that are “exceptionally well preserved and obviously come from the body of unknown sex.”
Archeologists found 9.7 million year-old teeth that might have belonged to a Lucy-like hominid.
It’s believed that these teeth belonged to a great ape that was potentially an early hominin species, one that could have been related to members of the African hominin tribe. The canine tooth, in particular, is indicative that this ancient being is unlike any other specimen found in northern Europe.
“It’s something completely new, something previously unknown to science,” Lutz told ResearchGate. “It’s a complete mystery where this individual came from, and why nobody’s ever found a tooth like this somewhere before.”
The Rhine River in Mainz, Germany.
While Lutz and his team are wary of speculating exactly what this finding means, they are hopeful that this finding can help fill in the holes of the fossil record and a new species could may be added to the family tree. These teeth most closely resemble the teeth of the famous early human Lucy, who existed 3.2 million years ago, and 4.4 million-year-old skeletal remains also found in Ethiopia. If subsequent analysis proves the researcher’s belief that these teeth are indeed 9.7 million years old, that would make this specimen much older — which raises questions about how the heck it got to Germany.

“It’s possible that, with the morphology of this canine tooth being so similar to more recent examples from Africa, the species could be related,” says Lutz. “That would mean that a group of primates was in Europe before they were in Africa.”
The dig site in Eppelsheim, Germany.
Another potential way this ancient European specimen could have had these advanced canines is via the phenomenon of convergence, an evolutionary biology process where organisms that are not closely related still independently evolve to share similar traits, even if they live in different areas and have never interacted. These traits evolve because both groups of organisms had to adapt to similar ecological niches.
Hopefully, answers will begin to emerge as the scientist begin to analyze the specimens. High-resolution x-rays will be used to examine the inner structure of the enamel, which will reveal information about how old the individual was and whether it developed healthily. They will also examine the wear-and-tear on the chewing surface of the teeth, which can indicate what it’s diet was like.
That’s not to say that the researchers aren’t acutely confident they have something big on their hands: They actually discovered the teeth a year ago, and are only now confident enough to publish a paper saying these 9.7 million-year-old chompers are the real deal.
“We want to collaborate with other researchers to process these finds, and hopefully in one or two years, we’ll know a lot more about what we’ve got on our hands,” says Lutz. “It’s definitely a fantastic, exciting story.”
Paleontologists in Germany have discovered 9.7 million-year-old fossilised teeth that a German politician has hailed as potentially “rewriting" human history
The dental remains were found by scientists sifting through gravel and sand in a former bed of the Rhine river near the town of Eppelsheim.
They resemble those belonging to “Lucy”, a 3.2 million-year-old skeleton of an extinct primate related to humans and found in Ethiopia.
However, they do not resemble those of any other species found in Europe or Asia.
Scientists were so confused by the find they held off from publishing their research for the past year, Deutsche Welle reports.
Herbert Lutz, director at the Mainz Natural History Museum and head of the research team, told local media: "They are clearly ape teeth. Their characteristics resemble African finds that are four to five million years younger than the fossils excavated in Eppelsheim.
“This is a tremendous stroke of luck, but also a great mystery."
At a press conference announcing the discovery, the mayor of Mainz suggested the find could force scientists to reassess the history of early humans.

"I don't want to over-dramatise it, but I would hypothesise that we shall have to start rewriting the history of mankind after today," he said.
Axel von Berg, a local archaeologist, said the new findings would “amaze experts”.
With the first paper on the research having just been published, the “real work” to unlock the mystery is only just beginning, Dr Lutz said.
Although there is abundant fossil evidence that great apes were roaming Europe millions of years ago, there has been no confirmed cases of hominins – species closely related to humans – on the continent.
Archaeological treasures of Ancient Greece
The current scientific consensus proposes that modern humans evolved out of east Africa somewhere between 400,000 and 200,000 years ago, before dispersing around the world as recently as 70,000 years ago.
The teeth will be on display from the end of October at a state exhibition, before heading to Mainz’s Natural History Museum.
The region where the find was made has been an attraction for fossil hunters for almost 200 years.
9,7 miljoen jaar oude fossielen kunnen menselijke geschiedenis herschrijven. Deze archeologen stuiten op groot mysterie
9,7 miljoen jaar oude fossielen kunnen menselijke geschiedenis herschrijven. Deze archeologen stuiten op groot mysterie
Duitse archeologen hebben 9,7 miljoen jaar oude fossielen gevonden die de menselijke geschiedenis weleens zouden kunnen herschrijven.
De tandresten zijn gevonden bij de plaats Eppelsheim en doen denken aan fossielen van Lucy, een 3,2 miljoen jaar oud skelet van een menselijke voorouder dat in Ethiopië is gevonden.
Ze vertonen echter geen gelijkenissen met botten van andere soorten die in Europa of Azië zijn gevonden, waardoor de Out of Africa-theorie op de tocht komt te staan.
Uitstelden
Wetenschappers waren zo verbaasd door de vondst dat ze de publicatie van hun resultaten een jaar uitstelden, schrijft Die Welt.
Hoofdonderzoeker Herbert Lutz, directeur van het Naturhistorisches Museum Mainz, vertelde aan lokale media: “Dit zijn duidelijk tanden van een aap. Ze doen denken aan Afrikaanse vondsten die vier tot vijf miljoen jaar jonger zijn dan de fossielen die in Eppelsheim zijn opgegraven.”
“We hebben ongelooflijk veel geluk gehad, maar het is ook een groot mysterie,” voegde hij toe.
Herschrijven
Tijdens een persconferentie over de ontdekking suggereerde de burgemeester van Mainz dat de vondst wetenschappers kan dwingen om de geschiedenis van de vroege mens te herzien.
“Ik wil de zaken niet dramatiseren, maar na vandaag zullen we denk ik moeten beginnen met het herschrijven van de menselijke geschiedenis,” zei hij.
De lokale archeoloog Axel von Berg zei dat de nieuwe bevindingen ‘experts zullen verbazen’.
Echte werk
Hoewel de eerste paper over het onderzoek net is gepubliceerd, is het echte werk pas net begonnen, aldus dr. Lutz.
De tanden worden vanaf eind oktober tentoongesteld. In het gebied waar de bijzondere vondst is gedaan zijn al bijna 200 jaar fossielenjagers actief.
Witnesses report landing of a UFO near São Paulo, Brazil
Witnesses report landing of a UFO near São Paulo, Brazil
A team of researchers investigate the alleged landing of an Unidentified Flying Object in Peruíbe, near São Paulo in Brazil..
The event already occurred in the early hours of October 7, but was kept confidential as not to attract the attention of onlookers. An official statement has been released on Thursday, October 19, 2017.
During the investigation local authorities decided to close the area, which is located at the back of a house on Rua 19, in the Balneário São João Batista 3 neighborhood, not too far away from the central part of the city, for the public, to avoid that onlookers could hamper the work of the researchers.
Residents living near the alleged landing site reported seeing a light on a terrain at dawn, afterwards they found marks on the vegetation.
Other residents reported that at the time of the alleged landing, the homes in the surroundings were without electricity, while a couple reported that they saw a beam of light on that ground, and in another moment, that light approached their house.
Researcher Saga Susseliton Souza explains: “We have looked at it and we already have noticed that it was something that was not made by a human. It was a UFO that landed there in circular movements, given the fact that the vegetation was not broken, but just bent.”
“Peruíbe Prefeitura has carried out the marking of the terrain and aerial images of the vegetation that was altered. We are still in the research phase, but we have already collected images, analyzed the terrain and heard the witnesses so we hope to get clarity on this strange event the coming days”, Sara said.

Moon-like Object circles around the Earth as a "quasi-satellite” Astronomers Say
Moon-like Object circles around the Earth as a "quasi-satellite” Astronomers Say
Was it a burned-out rocket booster, tumbling along a peculiar near-earth orbit around the sun, and only occasionally getting close enough to be studied with even the largest telescopes?
Not at all, as it turns out. While, based on previous observations, most astronomers had strongly suspected that object 2016 HO3 was an ordinary asteroid and not space junk, it took a team of astronomers led by Vishnu Reddy, assistant professor at the Lunar and Planetary Laboratory, University of Arizona, working with one of the world's largest telescopes, the Large Binocular Telescope (LBT), on Mt. Graham in Southeastern Arizona, to learn the true nature of this near-Earth object.
The astronomers are convinced that 2016 HO3 is a small near-Earth object (NEO) measuring no more than 100 meters (330 feet) across that, while orbiting the Sun, also appears to circle around the Earth as a "quasi-satellite.”
Although the provenance of the object is unknown it seems on timescales of a few centuries, this “quasi-satellite” (Black Knight Satellite?) remains within 38-100 lunar distances from us.
Author Claims People Close To Find The Truth About Death Planet Nibiru Are Kept Silence
Author Claims People Close To Find The Truth About Death Planet Nibiru Are Kept Silence
Mysterious death planet hurtling towards Earth has been in the news in recent times. The theories about it colliding our world have been circulating in different media outlets for many years. According to conspiracy theorist David Meade, politicians are already preparing for the cataclysm in nuclear bunkers.
The same man also suggests that mysterious Men in Black are responsible for the death of researchers who get too close to the truth. Meade believes astrophysicist Rodney Marks and Dr Robert Harrington both died of the common factor and that could be Planet X. He thinks there have been strange instances.
Meade stresses that Dr Harrington mysteriously died before he could say anything. Then in 2000, a man died of supposedly alcohol poisoning, according to Mead.
Dr Robert Harrington
Believers say that dozens have died since 1947, including JFK. They believe that the assassination of JFK may have been arranged to prevent him disclosing the truth on UFOs.
Nancy Lieder, a website writer who claimed to have an alien implant in her brain, predicted that Nibiru would destroy the world in 2003, but of course, it did not happen. In 2012, Planet X was predicted to destroy our planet to coincide with the Mayan apocalypse. It was also widely anticipated that the mysterious dead world would hit in December 2015, then in April 2016, but the predictions did not take place. It was also predicted again to hit Earth in December 2016, but with the same result. Now David Meade predicted it to happen on October 22.
Many do not believe the existence of Nibiru anymore, and one can only hope that David Meade has got his excuses ready on October 22.
NASA has thoroughly debunked the Nibiru, saying it is one of those Internet hoaxes with no factual basis.
However, believers say that Nibiru exists and it just a matter of time it will hit Earth and destroy our existence.
Army Military Ordered Off the Bait Diggers after Witnessing the Odd UFO
Army Military Ordered Off the Bait Diggers after Witnessing the Odd UFO
UFO is anything that is not explainable readily and that it appears to move through or at least is suspended in the air, used primarily to refer to the objects that seem to be of small yet familiar aircraft size. While most people believe that UFO is just a fictional character, they cannot deny the fact that there are too many people who witnessed them. Recently, two workers worked at the beach. These workers have claimed to have seen odd objects entering in the Wilsthorpe Beach, nearby the Bridlington in East Yorkshire. Paul Sinclair, the Paranormal investigator shares this story called the Wilsthorpe incident, which has been branded as the Britain’s latest Roswell owing to the mysterious military activity that is seemingly connected to the alien sightings. According to him, the two men were working at the bait shop nearby Bridlington Harbour when it occurred.
The two workers were at the Wilsthorpe digging during a high tide. It was a place where the bait shop owner told Mr Sinclair that they had reported seeing various bizarre triangles entering into the sea. Later on, they were surrounded by armed soldiers who asked them what they were doing and where they were going. They were being interrogated and were a bit off with them. However, one soldier threatened to arrest them if they are going somewhere. The bizarre claims of these two workers concerned the night of September 14, 2009, when the woman went to turn off the lights to sleep, and she saw a glow outside. Before she opened the front door to see what it was, the latter saw glowing several unidentified objects above the coast. It remained for half an hour. Next day, two helicopters full of RAF staffs landed at the beach.
Mr Sinclair submitted to the Ministry of Defence (MoD) a Freedom of Information request to know why the military operations took place on September 15. However, “routine military exercise”were the reasons for such operations. However, Mr Sinclair continues to investigate the case since he believes that such operation is connected to a UFO activity.
“Access Mars” provides 3-D views of the Red Planet as captured by NASA’s Curiosity rover. (NASA / JPL Illustration)
NASA has been offering virtual-reality tours of Mars for years — but now, with Google’s help, the space agency has come up with one of the most accessible tours yet.
“Access Mars” lays out a 3-D terrain for five of the spots scanned by NASA’s Curiosity rover, ranging from its landing site to the place where it’s hanging out now, more than five years later.
The tour can be experienced via a desktop browser, on mobile devices as a head-tracking display seen through a Cardboard-style viewer, and on virtual-reality and augmented-reality headsets.
You can jump from one spot to another, teleport between the five tour stops, or check out explanatory placards that are accompanied by audio narration. There’s even the sound of wind in the background to give you an eerie sense of Martian aloneness.
NASA says the experience was adapted from the Jet Propulsion Laboratory’s OnSight software, which is used to help scientists visualize the rover’s surroundings as they plan its route. The software was developed using WebVR, an open-source standard, with support from Google’s Creative Labs team.
“We’ve been able to leverage VR and AR technologies to take our scientists to Mars every single day,” Victor Luo, lead project manager at JPL’s Ops Lab, said today in a NASA news release. “With ‘Access Mars,’ everyone in the world can ride along.”
NASA’s other forays into VR and AR include “Mars 2030,” an immersive VR experience created in collaboration with Fusion Media Group; “Destination: Mars,” a mixed-reality presentation that NASA and Microsoft put together for NASA’s Kennedy Space Center Visitor Center in Florida; and ProtoSpace, a Hololens application that JPL is using to tweak the design for NASA’s 2020 Mars rover.
The 11-minute video takes you on a tour of six extrasolar planets, ranging from Osiris, a storm-ravaged “hot Jupiter” that orbits a star 154 light-years from Earth, to Kepler-62e, a potential water world that’s 1,200 light-years away and is thought to have a super-ocean.
Like “Access Mars,” the exoplanet tour can be experienced on a desktop, a mobile phone or with a headset in head-tracking 3-D. There’s a running commentary that’s provided by planetary scientists from the University of Exeter Astrophysics Research Group. Funding was provided by the University of Exeter.
We won’t really know what these exoplanets look like until we create telescopes big enough to get a snapshot. But the views come close to scientists’ conceptions — so close that NASA used the imagery of WASP-121b to illustrate a report about the weird planet’s stratosphere in August.
