In early 2005, the late Rob Riggs – the author of the book In the Big Thicket, and who I had first met in the summer of 2003 – telephoned me and asked if I would be interested in speaking at a conference he was planning on soon holding in the city of Austin, Texas. The subject was “ghost lights,” and the links between that same phenomenon and sacred sites, stone circles, and Bigfoot-like entities. I replied that, yes, I would definitely be interested. And thus was born the Texas Ghost Lights Conference. It was held at Austin’s First Unitarian Universalist Church on Saturday, June 11. Precisely what the God-fearing folk of the Church thought about a group of Bigfoot-hunting, ghost-light-seeking adventurers descending upon their property, I never learned. But, they didn’t seem to mind at all.
In addition to Rob and me, the other lecturers were James Bunnell and Paul Devereux. James has an interesting background: the author of two books on the famous “Marfa Lights,” namely Night Orbs and Seeing Marfa Lights. he was an aeronautical and mechanical engineer by profession, and retired in 2000 from BAE Systems as Director of Mission Solutions for various U.S. Air Force programs. Like me, Paul is a Brit. He’s a longstanding, prestigious figure in the field of ghost-light style phenomena.
Big Thicket National Preserve
In addition to organizing the conference, Rob had also put into place something that he termed the Bragg Road Project. Essentially, it was a road-trip to the Texas-based Big Thicket (a hotbed for “ghost lights”)that he had planned for the day after the Austin gig. The idea was to travel down to the woods of east Texas and hang out in the area for two nights, in the event that something – be it a ghost light or a Bigfoot, or both if we were that lucky – decided to make an appearance.
Early on what turned out to be a bright and sunny Sunday morning, me, Rob, James, Paul, S. Miles Lewis of the Austin-based Scientific Anomaly Institute, and two conference attendees, Renee and Nancy, met at a prearranged location for our journey into the unknown. I can hardly say that the trip was one of proportions that would have made Jack Kerouac proud. But nevertheless, we were on a mission and everyone was fired up about what we might uncover, and so our convoy set off in earnest. It was late afternoon when we finally arrived in the town of Kountze, where all of us had reservations at the local Super 8. And, after a shower and a Mexican dinner, we were forest-bound. And this was where, as was so often the case, things got very strange.
Bragg Road can be an eerie location during daylight – as I had found to be so when I ventured deep into the Big Thicket with Rob in the summer of 2003. At night and under the spotlight of a full moon, however, it was truly spooky. Not in a scary sense, as I always relish the opportunity to check out such places, but just from the perspective of believing that quite possibly anything could happen here. Of course, it’s important to note that more than a few people have mistaken distant car headlights for the legendary lights (as Andy Collins notes at this link). But, given that some sightings have occurred within just a feet of eyewitnesses demonstrates that not all cases can be written off so easily.
With flashlights in hand, we began a walk through the darkened woods, with Rob pointing out to us various locations where wild men, Bigfoot, and, of course, ghost lights had been seen and reported for decades. For twenty minutes or so, we walked around, seemingly forever trying to avoid the overwhelming mass of mosquitoes that surrounded us, while at the same time negotiating the thick blanket of ancient and mighty trees that dominated the area. And then, suddenly, it happened. We were on our way back to the vehicles to grab a bite to eat and some drinks when, as we entered a clearing in the trees, a basketball-sized bright light floated over us at a height of about thirty-five feet. It was moving from right to left, and sailed slowly yet purposefully on its journey. The ghost light was present for barely a handful of seconds, but it was definitely there.
Due to work, I was unable to stay for the second night, but when I got back to Dallas and turned on the computer, I read an email from Rob that was of true jaw-dropping quality. The odd experiences of the first night in the Big Thicket were apparently not isolated. As Rob said: “Renee had a frightening experience Monday night. We split up into teams of two and spread out about a mile apart. Renee was paired with Nancy. Nancy walked down the road briefly away from Renee. Renee said she then heard something walking in the woods off the road directly behind her that sounded large. She said whatever it was, was large enough to snap twigs, and she said that it seemed to be moving stealthily, as if it were trying to sneak up on her. She panicked, locked herself into her van and drove off, leaving Nancy to fend for herself.”
Rob continued: “Several hours later she was still shaken and still had goose bumps. Such irrational panic is not characteristic of Renee. She is a ghost hunter and has many times been in creepier situations than being on Bragg Road. She has even gone to cemeteries alone just to test her mettle. There are theories that the creatures deliberately provoke such panic reactions through chemicals in their scent or by mental projection of energy.”
He concluded: “Renee, Nancy and I also saw a peculiar light. It looked somewhat like a firefly but actually left a solid streak 10 – 15 feet in length that was brilliant bluish-white in color. It happened near a power line, and it was suggested that it might have been some kind of surge on the power line itself. But what could cause such a surge? That, in itself would be suggestive of a electromagnetic anomaly.”
Rob’s research into the matter of Texas’ ghost lights continued until his death in 2015.
Well, it happened and we’re all still here. Egyptian archaeologists have opened the giant, mysterious black marble sarcophagus recently unearthed in Alexandria, and…
A whole lot of stinking sewage water fell out. No curse, no vengeful mummy, no evil necromancer. No hieracosphinx, no serpopard, no Ammit, damnit. Not one Nazi’s face melted off. I guess we can’t be too disappointed, though – the world is still here and only somewhat doomed, as opposed to covered in locusts and horrible man-eating beasts out of Egyptian mythology. So what exactly was found in this once-in-a-lifetime archaeological find?
The usual. Just some old dead people.
According to initial reports, three skeletons and a whole lot of “red-brown sewage water” which filled observers’ nostrils with what the BBC describes as “an unbearable stench” that sent researchers fleeing from the inspection scene entirely. At least that much was awesome.
The sarcophagus was opened by a specially-appointed committee of specialists on behalf of the Egyptian Ministry of Antiquities. Mostafa Waziri, secretary-general of the Supreme Council of Antiquities, says that while the find is unique, it’s ultimately a little disappointing:
We found the bones of three people, in what looks like a family burial… Unfortunately the mummies inside were not in the best condition and only the bones remain. We’ve opened it and, thank God, the world has not fallen into darkness. I was the first to put my whole head inside the sarcophagus… and here I stand before you. I am fine.
Yeah, fine so far, Mostafa. Sometimes ancient Egyptian curses can take a few decades to catch up with you. Come back to me when you develop prostate cancer in 16 years.
It took 16 years for the Curse of the Pharaohs to catch up with Howard Carter.
Actually, don’t; I don’t wish that upon anyone. I’m just bitter and a little disappointed. Like most of us, I was hoping something truly marvelous would have been inside of this mysterious, imposing sarcophagus. Instead, it appears that this was some type of ritual burial for three soldiers who served during the time of the Pharaohs. It’s unknown who they were, but one of the skulls bears an arrow injury, suggesting a warrior. Still, given the nature of their burial, it’s likely they have an interesting story to tell.
I guess it’s great and all that the world is still here, but deep down I was hoping for an evil wizard. Just once before I die, I want to witness the awe-inspiring, spacetime-bending power of an ancient undead necromancer. Is that too much to ask?
Mysterious radio signals have long been a mainstay of science fiction tales, but lately they’ve also been the subject of serious scientific scrutiny. Radio bursts originating from deep spacehave become a hot topic in the astronomy world, and while most of these appear to be naturally occurring, you never know when one of them turns out to be something far stranger. At least, we can hope one of them will. Here on boring planet Earth, mysterious radio signals often pop up in the form of pirated transmissions broadcasting strange, cryptic messages. While most of these turn out to be merely hoaxes or pranks, many of them also remain unexplained.
A radio telescope at the Parkes Observatory.
Just this week, physicists studying cosmic rays in Antarctica have uncovered a strange radio signal that appears to have a mysterious origin. The physicists are part of the Antarctic Impulsive Transient Antenna (ANITA) program, a project which uses balloons to locate and identify signals produced by strange particles travelling from deep space as they collide with the Earth. However, this latest signal appears to originate from deep within the Earth itself. Is this a lost race of molemen and molewomen’s attempt at communication with us surface dwellers?
Unfortunately, it doesn’t appear so. Or maybe fortunately, those things look like they could eat a human brain or two. According to a press release issued by Physics World, the strange radio signal is likely the product of neutrinos colluding with atomic nuclei deep within Antarctic ice sheets. These collisions produce explosions of charged particles which emit radio waves that then bounce through 7,000 kilometers of ice and the Earth’s crust and into the air where ANITA balloons detect them. Neutrinos are a little-understood cousin of the other subatomic particles which don’t seem to interact with other particles and fields as much as other elementary particles do. Scientists believe neutrinos might someday be used in deep space communications, as they are capable of travelling through matter and across long distances unscathed.
Peter Gorham of the University of Hawaii is one of the ANITA researchers behind this discovery. Gorham notes that while it’s possible human activity created these anomalous radio signals, the data more likely point to this extremely rare interaction between deep space neutrinos and Antarctic ice sheets. “It’s still possible that the events are due to two isolated people, each transmitting a single radio pulse very far from the nearest Antarctic base, Gorham says. “But that seems very unlikely at this stage.”
The Sudbury Neutrino Observatory located 2100m underground in a mine in Canada.
It’s pretty amazing to think about: strange, exotic particles flying through unimaginably vast reaches of space only to penetrate deep within the Earth and explode into a shower of radio waves which are then detected by a weather balloon. I consider myself a proponent of science and scientific explanation, but the history of science and scientific knowledge proves that each explanation isn’t necessarily the definitive answer, but only the best answer we have at the time given current methods, instruments, and data. Could there be an even more exotic explanation for these anomalous radio signals originating from deep within the Earth that we haven’t even considered yet?
REAL X-FILES Secret files reveal MI5 spent 50 YEARS hunting UFOs in bid to steal alien tech to make super-weapons – and feared Russia already had flying saucers
REAL X-FILES - Secret files reveal MI5 spent 50 YEARS hunting UFOs in bid to steal alien tech to make super-weapons – and feared Russia already had flying saucers
Alien experts claim there have been more than 100,000 recorded UFO sightings worldwide in the past 100-plus years
By Sofia Petkar
A SECRET dossier has revealed that British spies spent at least 50 years hunting UFOs in the hope of stealing alien technology.
The declassified files confirm that British spies were desperate to build their own super-weapons amid fears either China or the Soviet Union had already impounded a UFO.
The other worked in the background and did the “real work” of sending spies to investigate these claims.
These ‘UFO desks’ ran until 1997, until Whitehall expressed concern that security services “investigating X files stuff such as alien abductions” had started becoming diverted from their main duties.
While the desks were shut down with immediate effect, officials wanted to know if anything had been learned over the past half century that could be useful for military purposes.
A report entitled “UAPs” (Unidentified Aerial Phenomena) in the UK Air Defence Region set to be released after being declassified.
The report makes up a part of three files running to more than 1,000 pages which were held back from the UFO records earmarked for transfer to the National Archives as part of the Open Government project from 2008 to 2013.
Earlier this year, complete set of redacted copies was released to investigative journalist and university lecturer Dr David Clarke, ahead of their imminent release to the National Archives.
Dr Clarke was also the curator for The National Archives UFO project from 2008–13, and regularly comments in national and international media on UFOs.
These documents revealed how the RAF expressed great interest in finding UFOs to help come up with new and innovative ways of being their enemies during the Cold War.
They also reveal how spies were given tips on what to look out for when identifying foreign objects.
According to one unnamed commander documented in the dossier, particular attention needed be paid to any aircraft behaving “like a UFO”.
He said: “Look out for high velocities, sharp manoeuvre, stationary 'flight', and few radar returns.”
Dr Clarke said: “The MoD have been desperately trying to delay the release of these formerly secret and highly sensitive papers for more than a decade.
“Even though they have been partly censored they can't conceal the fact the UK military were interested in capturing UFO technology - or what they coyly refer to as 'novel weapon technology'.
“And the files reveal they were desperate to capture this technology - wherever it came from - before the Russians or the Chinese got hold of it first.
“Although this was 1997, Russia was still regarded as undefeated enemy with a weapons programme regarded as a threat to the West.”
Alien experts claim there have been more than 100,000 recorded UFO sightings worldwide in the past 100-plus years.
Secret Documents Reveal MI5 Used To Hunt For Alien UFO Technology To Make Super Weapons
Secret Documents Reveal MI5 Used To Hunt For Alien UFO Technology To Make Super Weapons
Alien enthusiasts claim there have been over 100,000 recorded UFO sightings around the world in the past 100-plus years.
A secret collection of papers containing detailed information has reportedly revealed that British investigators spent at least 50 years searching for UFOs in the hope of stealing alien technology. They were looking to build their super-weapons amid fears that either the Soviet Union or China had already impounded a UFO.
Dated between 1947 and 1997, the cache suggests intelligence services had not only one but two desks based around the idea of space alien visitors to Earth.
While one desk has been known to the public for taking calls from concerned citizens about possible UFO sightings, the other one worked in the background. The alleged secret office did the real work of sending spies to look into UFO claims.
Both UFO desks ran until 1997 when Whitehall expressed concern that services had begun becoming diverted from their primary duties. After the shutdown, officials wanted to know what had been learned out of the two desks that could be useful for military purposes.
A report titled Unidentified Aerial Phenomena (UAPs) in the Air Defence Region of UK is set to be released after being declassified.
The report includes three files containing more than a thousand pages that were kept secret from the UFO records, which are scheduled for transfer to the National Archives as part of the Open Government project from 2008 to 2013.
The complete set of redacted copies was released ahead earlier this year to investigative journalist and Dr David Clarke, a university lecturer and curator for The National Archives UFO project from 2008 to 2013.
These documents revealed that the RAF expressed great interest in discovering UFOs to help come up with innovative ways to gain military advantage. Also disclosed is how spies were provided with tips about what to look out when identifying unknown objects.
Documented in the dossier is particular attention to be paid to any aircraft suspected to be a UFO.
One unnamed commander instructed to look out for high velocities, few radar returns, stationary flight and sharp manoeuvre.
Dr Clarke accused the MoD of desperately trying to delay the release of these formerly secret papers for over a decade.
He said that the documents had been partly censored but the fact the UK military was interested in getting UFO technology can’t be concealed.

The USS Nimitz Carrier Strike Group tracked UFOs not just one but many occasions that lasted for several days off the coast of San Diego in 2004. A secret group investigating UFOs within the Pentagon turned out to be the investigative team of the event.
The existence of this UFO project caught the attention of media organizations worldwide, including the New York Times that published an article on the subject in December 2017.
Many articles worldwide mentioned this case and included video of one of the UFOs from a jet fighter’s infrared camera. However, the government shared very little official information beyond the video.
Former head of the UFO program Luis Elizondo and one of the fighter pilots in the incident David Fravor have come forward in media interviews.
Unfortunately, no documents have been made public. Recently, Las Vegas’8 News Now’s I-Team released an alleged leaked report they got from the incident and it was shocking.
Below are recent interviews with David Fravor by filmmaker Jeremy Corbel and with Luis Elizondo from Las Vegas 8 News Now.
Antarctica’s Pine Island Glacier is melting, thanks to warming waters from below. What’s more, a recent study has discovered a volcano beneath the glacier.
This article is republished with permission from GlacierHub. This post was written by Andrew Angle.
West Antarctica’s Pine Island Glacier (PIG) is the fastest-melting glacier in Antarctica, making it the single biggestcontributor to global sea-level rise. The main driver of this rapid loss of ice is the thinning of the PIG from below by warming ocean waters due to climate change. However, a study, published June 22, 2018, in Nature Communications, discovered a volcanic heat source beneath the PIG that is another possible driver of the PIG’s melting.

Study lead author Brice Loose spoke to GlacierHub about the research. He said that the study was a result of a larger project funded by the National Science Foundation and the U.K. National Environmental Research Council to
… examine the stability of the Pine Island Glacier from the terrestrial and the ocean side.
The West Antarctic Ice Sheet (WAIS), which includes the PIG, sits on top of the West Antarctic Rift System that includes 138 known volcanoes. It is difficult, however, for scientists to pinpoint the exact location of these volcanoes or the extent of the rift system, because most of the volcanic activity occurs below kilometers of ice.
The Pine Island Glacier from above taken by Landsat Image via NASA.
Warming ocean temperatures due to climate change have long been identified as the primary contributor to the extensive melting of the PIG and other glaciers that transport ice from the WAIS. This melting is largely driven by Circumpolar Deep Water (CDW), which melts the PIG from below and leads to the retreat of its grounding line, the place where the ice meets the bedrock.
To trace CDW around coastal Antarctica, the scientists used helium isotopes, specifically He-3, because CDW is widely recognized as the principal source of He-3 in the waters near the continent. For this study, the scientists used historical data of helium measurements from the Weddell, Ross and Amundsen seas around Antarctica. They looked at the three seas, all of which have CDW, and examined differences in He-3, which could have come from volcanic activity.
By tracing the glacial meltwater produced by the CDW, the researchers discovered a volcanic signal that stood out in their data. The helium measurements utilized were expressed by the percent deviation of the observed data from the atmospheric ratio. For the observed CDW in the Weddell Sea, this deviation was 10.2 percent. In the Ross and Amundsen Seas, it was 10.9 percent. However, HE-3 values gathered by the team during expeditions to the Pine Island Bay in 2007 and 2014 differed from the historical data.
For this data, the percent deviation was considerably higher at 12.3 percent, with the highest values being near the strongest meltwater outflow from the PIG’s front. Additionally, these high helium values coincided with raised neon concentrations, which are usually an indication of melted glacial ice. The helium was also not uniformly distributed. This suggests it originated from a distinct meltwater source and not from across the PIG’s entire front.
With this knowledge in hand, the team of scientists endeavored to identify the source of the HE-3 production. The Earth’s mantle is the largest source of HE-3, although it is also produced in the atmosphere and during past atmospheric tests of nuclear weapons through tritium decay. These two sources, however, could only account for 0.2 percent of the 2014 data.
Another potential source was a fissure in the earth’s crust directly below the PIG, where He-3 could rise from the mantle. However, this source was ruled out as it would have a strong thermal signature, something that was not discovered by mapping expeditions.
Map of He-3 samples around Antartica (yellow = 2007, red = 2014)
The researchers then considered another source: a volcano beneath the PIG itself, where He-3 escapes from the mantle in a process known as magma degassing. The He-3 could be transported by glacial meltwater to the PIG’s grounding line, where the ice meets the underlying bedrock. At this line, the ice shifts due to the ocean tides, allowing the meltwater and the He-3 to be discharged into the ocean.
After identifying a subglacial volcano as the most likely source of the elevated He-3 levels near the PIG’s front, the scientists next calculated the heat released by the volcano in joules per kilogram of sea water at the front of the glacier. It turned out that the heat given off by the volcano constitutes a very small fraction of the overall mass loss of the PIG compared to the CDW, according to Loose.
In total, the volcanic heat was 32 ± 12 joules kg-1, while the heat content of the CDW was much larger at 12 kilojoules kg-1. Nevertheless, if the volcanic heat is intermittent and/or concentrated over a small surface area, it could still have an impact on the overall stability of the PIG by changing its subsurface conditions, said Loose. There is also the possibility that the continued melting of the PIG could lessen the pressure and weight on the volcano, spurring more volcanism and subsequent melting.
The presence of an active volcanic heat source beneath the world’s fastest-melting glacier is a disturbing discovery that threatens to accelerate the PIG’s contribution to future sea-level rise. To develop a better understanding of how the volcano might impact the PIG, Loose stated that future studies should examine how the volcanic signal varies from year to year and attempt to pinpoint the likely location of the volcano itself beneath the ice.
Active volcano discovered beneath Antarctic ice sheet
Bottom line: A recent study discovered a volcano beneath Antarctica’s Pine Island Glacier.
Scientists Just Discovered 12 New Jupiter Moons - One Of Them Is On A Collision Course
Scientists Just Discovered 12 New Jupiter Moons - One Of Them Is On A Collision Course
Scientists have discovered 12 new moons that orbit Jupiter, but it appears there is an issue: one moon is on a suicide mission!
Researchers came across the new discovery during a search for the mysterious Planet X said to be hiding outside of Neptune`s orbit. If found it would make it the most distant planet out there.
The researchers found the moons back in March of last year thanks to the Cerro Tololo Inter-American Observatory in Chile. However, they did not want to report them and kept them quiet for more than a year so they could get confirmation that they were in orbit around Jupiter.
The Discovery of the New Moons Mean Jupiter Now Has 79 in Total
Jupiter, of course, is known for its big amount of moons, but the addition of twelve more means that in total there are 79 moons in orbit around the planet.
Nine of these moons are in an outer group orbiting around Jupiter in retrograde, which means they are traveling in the total opposite direction to the spin of the planet. Scientists believe they are what is left over of the bigger parent bodies probably broke up with they collided with comets, asteroids, and moons.
In prograde orbit around Jupiter, there are two moons, and they are traveling in line with the spin of Jupiter. These are pieces of a bigger moon that were broken in orbit, and these take about one year to go around the planet.
The 12th new moon that scientists discovered has been called the oddball moon as it is less than one kilometer in width with the body circling Jupiter at a distance crossing path with the other new moons found.
The new moon Valetudo was given the name from the great-granddaughter of the Roman god Jupiter, goddess of health and hygiene. Valetudo is on a collision course that could end in destruction the name Vale Tudo is appropriate when using the Portuguese translation, which means “anything goes”, which is a form of full-contact martial arts.
Sheppard said:
“Valetudo is like driving down the highway on the wrong side of the road. It is moving prograde while all the other objects at a similar distance from Jupiter are moving retrograde. Thus head-on collisions are likely.”
NEW MOON, I SAW YOU ORBIT ALONE Of 12 recently discovered Jovian moons (illustrated in bold orange, blue and green), one orbits in the opposite direction of its neighbors (arrows show orbit direction). Four moons discovered by Galileo are also shown (purple).
ROBERTO MOLAR CANDANOSA/CARNEGIE INSTITUTION FOR SCIENCE
Astronomers have found 12 more moons around Jupiter, and one is really weird. While 11 orbit in the same direction as their nearest neighbors, one doesn’t, potentially putting it on a fatal collision course.
“It’s driving down the highway on the wrong side of the road,” says planetary scientist Scott Sheppard of the Carnegie Institution for Science in Washington, D.C.
Astronomers Just Discovered 12 NEW Moons Around Jupiter
Sheppard and colleagues found the moons while looking for something else entirely: a putative planet that could exist beyond the orbit of Neptune, known colloquially as Planet Nine (SN: 7/23/16, p. 7). During a survey in 2017 of the most distant objects in the solar system using the Victor Blanco 4-meter telescope in Chile, Jupiter happened to be visible in the same area of sky that the team was searching during one of its observing runs. “Might as well kill two birds with one stone,” Sheppard thought.
The researchers found a dozen objects moving around the sun at the same rate as Jupiter. Follow-up observations confirmed the moons’ existence and orbits: two inner moons that orbit in the same direction that Jupiter spins, nine outer moons that orbit the planet in the opposite direction and one oddball traveler. The researchers announced two of the moons in 2017 and the remaining 10 on July 16.
The motions of all but the oddball are normal for Jovian moons, which now number a whopping 79. Scientists think that’s because the inner moons formed from a disk of gas and dust that orbited the giant planet in the solar system’s early days, similar to how the planets formed around the sun (SN: 5/12/18, p. 28). The outer moons were probably free-floating space rocks captured when they came too close, and their opposite orbit was set by the direction that they approached Jupiter from.
But one moon broke the mold. This rock, which the team calls Valetudo for the Roman goddess of health and hygiene, is tiny, only about a kilometer across. It orbits in the same direction as Jupiter’s spin, but alongside the farther-out retrograde moons. As a result, Valetudo is probably doomed to collide with one or more of the other moons someday. The researchers are still calculating when, but they expect it to occur sometime between 100 million and a billion years from now.
Valetudo may be the last remnant of a bigger object that has already withstood several collisions, or of a family of moons that has since been smashed to smithereens. “It’s probably the largest surviving member, if not the only one,” Sheppard says.
Such nonconformist satellites are not rare, notes planetary scientist David Jewitt of UCLA, who was not involved in the new work. “But they are very interesting, because we know that they have been captured by their host planets, but we don't know how, or from where,” he says. Figuring out what oddballs like Valetudo are made of could help nail those details down.
Editor's note: This story was updated July 18, 2018, to clarify that of the 12 newfound moons, two were announced in 2017 and the remaining 10 on July 16.
Ce que la science actuelle sait des extraterrestres
Ce que la science actuelle sait des extraterrestres
Plus que jamais, la quête d’une vie extraterrestre passionne les chercheurs. Succès en Angleterre, «Aliens», publié pour la première fois en français cet été, fait le point sur ce que l’on sait de nos potentiels voisins de galaxie
Virginie Nussbaum
Depuis près de soixante ans, la science a les yeux rivés sur les étoiles. En 1959, le SETI, institut dédié à la recherche d’intelligence extraterrestre, voyait le jour et, depuis, des millions de kilomètres de cosmos ont été scannés et inondés d’émissions radio.
Mais où en est-on aujourd’hui? L’Univers est-il désespérément vide, ou y a-t-il des raisons de croire que nous ne sommes pas seuls? Pour faire le point, Jim Al-Khalili, professeur britannique de physique théorique à l’Université de Surrey, s’est entouré d’une douzaine de scientifiques de tous bords.
Dans Aliens, vendu à plus de 50 000 exemplaires en Grande-Bretagne et publié cet été dans sa version française, ils décortiquent les quelques certitudes et nombreuses inconnues qui subsistent quant à nos potentiels voisins de galaxie.
Le Temps: Sommes-nous à un tournant dans notre exploration de l’espace?
Jim Al-Khalili: On peut dire ça, oui! Ces dernières années, des avancées dans le domaine de l’astronomie ont rendu la recherche de vie dans l’espace… faisable, tout simplement. Au lieu de nous contenter de pointer un radiotélescope en espérant capter quelque chose d’intéressant, les technologies actuelles nous permettent d’identifier des planètes semblables à la Terre, à l’image de Proxima b, découverte en 2016 à quelques années-lumière d’ici. En 2020, un nouveau télescope, nommé James-Webb, promet d'étudier encore plus précisément la lumière venue d'autres systèmes stellaires. Des recherches pour le moins respectables, alors que les scientifiques, qui les associaient aux théories du complot et aux petits hommes verts hollywoodiens, les ont longtemps dédaignées.
Le cinéma, comme la littérature, s’empare en effet inlassablement du sujet. Pourquoi cette fascination pour la figure de l’alien?
Parce qu’elle nous renvoie à une question fondamentale: sommes-nous seuls dans l’Univers? Et d’où venons-nous? Pour les croyants c’est simple, Dieu a créé cette planète et nous avec. Mais, scientifiquement, nous aimerions comprendre pourquoi, dans un espace que l’on sait immense, nous ferions office d’exception.
Au contraire, on entend souvent que, au vu de l’immensité de l’Univers, nous devrions avoir un alter ego quelque part…
Ce qui est vrai, c’est que les planètes réunissant tous les ingrédients favorables à la vie – l’eau, l’énergie et le carbone – sont bien plus nombreuses qu’on l’imaginait. On pense même que, sous leurs couches de glace, les lunes de Saturne et Jupiter pourraient être des candidates! Mais ça ne signifie pas pour autant que la vie y soit née comme sur la Terre, ou ait jamais dépassé le stade de cellule microbienne unique.
Car notre propre évolution est le résultat d’une longue chaîne de coïncidences.
Exactement. Et puisque nous n’avons que notre exemple sous la main, nous ne pouvons pas encore chiffrer statistiquement la mince probabilité que ce cas se reproduise. Personnellement, j’ai la conviction que nous observerons des signes de vie microbienne extraterrestre de mon vivant encore.
Et si nous détectons effectivement des voisins, à quoi pourraient-ils ressembler?
Nous avons tendance à tout antropomorpher: notre alien typique est un E.T., avec deux bras, tout au plus quelques doigts en moins… alors que notre apparence est totalement accidentelle! Le filmPremier contact, sorti en 2016, est intéressant à ce niveau car il représente les extraterrestres sous la forme de pieuvres immenses, dont l’intelligence se révèle très éloignée de la nôtre. En réalité, il y a plus de chances que les extraterrestres ne nous ressemblent pas du tout.
Ou qu’ils prennent la forme de machines, comme le suggère votre livre?
En effet. Pensez à l’humanité: nous utilisons déjà des robots alors que nous en sommes au tout début de nos explorations. Il y a fort à parier que, d’ici à quelques centaines d’années, l’intelligence artificielle voyagera pour nous, car elle survit dans des conditions extrêmes. Logiquement, ceux qui nous rendraient visite aujourd’hui devraient être en avance sur nous technologiquement parlant. Il est donc probable qu’ils nous apparaissent sous la forme de machines en silicone plutôt que d’êtres biologiques.
Il se pourrait que les aliens nous aient devancés au point d’avoir déjà disparu…
C’est possible. Sur l’échelle temporelle du cosmos, notre fenêtre de recherche est plus qu’étroite. Peut-être que des civilisations se sont formées puis éteintes il y a des milliards d’années, et que nous avons tout bonnement manqué la fête.
Votre livre pose une autre question intéressante: s’ils existent, pourquoi les aliens entreraient-ils en contact avec nous?
Dans les scénarios hollywoodiens, on les imagine nous attaquer, nous manger ou encore nous utiliser à des fins de procréation. Pourtant, rien ne peut nous assurer que cette forme de vie serait elle aussi basée sur l’ADN, et donc que ces interactions auraient un sens. Et que pourrait-on posséder que cette civilisation avancée n’ait pas déjà? Non, je pense que sa motivation serait avant tout la curiosité. Vouloir savoir et comprendre n’est pas un trait humain, mais un trait d’intelligence.
Pour résumer, nous investissons du temps et des sommes folles à chercher quelque chose d'hautement improbable...
Cet argument revient régulièrement, dans toutes les branches scientifiques: pourquoi rechercher le boson de Higgs au Cern plutôt qu'une cure contre le cancer? Mais comprendre le monde et comment il fonctionne est ce qui nous rend humain. Et nous continuerons à le faire.

Alien Planets Without Oxygen Could Still Be Home To Extraterrestrial Life
Alien Planets Without Oxygen Could Still Be Home To Extraterrestrial Life

The search for extraterrestrial life should not disregard planets with zero oxygen, as these other worlds may just be teeming with microbial life.
A team of researchers has found huge fluctuations in oxygen levels of ancient Earth that took place before the Great Oxidation Event.
They believe the same fluctuations could be happening in other planets, which means it is possible that planets with undetectable oxygen could be home to simple microorganisms that dominated the Earth a few billion years ago.
The Great Oxidation Event
Researchers at the University of Washington have found that, for hundreds of millions of years before the Great Oxidation Event, oxygen levels varied tremendously.
Around 3.5 billion years ago, the only life forms on the planet were one-celled microorganisms, such as the blue-green algae called cyanobacteria.
These simple microbes evolved a way to make their own food by using sunlight to create sugar out of water and carbon dioxide. The process, called photosynthesis, created oxygen as a waste product, which the bacteria released into the atmosphere.
Over a billion years, some experts believe the one-celled cyanobacteria became multicellular, allowing it to pump more oxygen into the atmosphere in an event that changed the course of the planet.
A Minor Whiff Before The Major Event
The Great Oxidation Event, which is believed to have happened between 3 and 1 billion years ago, is one of the defining moments in Earth's history. Without the rise of oxygen levels, plant and animal species seen today, including humans, would not be around.
However, the researchers say they have found an instance of rising oxygen levels before the Great Oxidation Event took place. This ancient "whiff" shows that oxygenation did not happen in a single geological breath. It was a complex process characterized by ebbs and flows in oxygen levels.
"The production and destruction of oxygen in the ocean and atmosphere over time was a war with no evidence of a clear winner, until the Great Oxidation Event," says lead author Matt Koehler, PhD student in Earth and space sciences.
Implications For The Search For Alien Life
The findings, published in the Proceedings of the National Academy of Sciences, could keep researchers involved in the search for alien life from discounting false negatives, such as planets that may not have detectable oxygen levels.
When searching for signs of life in other planets, experts look for biosignatures that increase the possibility of success. One of these is the presence of oxygen. However, just because a planet does not have oxygen does not mean life cannot exist on it.
Ancient Earth, after all, was teeming with bacteria at least a billion years before the planet's oxygen levels rose. The researchers believe it is entirely possible that a planet with no oxygen may just be in the ebb phase of its own oxygenation event.
"One of the strongest atmospheric biosignatures is thought to be oxygen," says coauthor Roger Buick, "but this study confirms that during a planet's transition to becoming permanently oxygenated, its surface environments may be oxic for intervals of only a few million years and then slip back into anoxia."
Rock Samples Show Signs Of Oxygen
By analyzing sediment samples collected at the Jeerinah Formation in Western Australia, Koehler's team found rising oxygen levels that took place 2.66 billion years ago.
The minor oxygenation event lasted 50 million years, which is hardly a blink in geological time, and spanned hundreds of miles across a wide body of water.
The researchers looked for traces of nitrogen isotopes and selenium in the rock layers. Both are indications of the presence of oxygen.
They found a gradual rise in nitrogen isotopes ended by an abrupt disappearance, leading the researchers to believe that oxygen levels gradually rose before immediately dropping off.
They also found traces of selenium in a shallow part of the marine basin, which means the selenium must have come from the land. When oxygen levels are high, more selenium gets drained into the sea through the rusting of rocks and is deposited into ocean sediments.
The samples collected by the researchers show high selenium levels in the sediments, suggesting that there was an oxygen spike in the atmosphere at the time.
In 2007, an international team of researchers also discovered a similar whiff that took place 50 to 100 million years before the Great Oxidation Event.

It’s been nearly four years since the Japanese spacecraft Hayabusa-2 blasted off, heading for a small asteroid that was then known only as 1999 JU3.
Back then, we didn't have many details about 1999 JU3—not even a good picture of the object. But JAXA, the Japanese space agency, still planned to visit it with Hayabusa-2, use explosives to blast debris off its surface, scoop up the fresh asteroid dust and return its cargo back to Earth, after depositing a few mini-rovers on the surface of the asteroid, of course.
The asteroid needed a better name. Eventually it was reborn as Ryugu, the name of the underwater palace of the Dragon God in Japanese mythology. The hero in one Japanese legend visits Ryugu and returns with precious cargo, a trajectory that Hayabusa-2’s creators hope to emulate with more success than the original Hayabusa mission. While that sample-return mission to an asteroid did succeed in bringing back a very small sample of asteroid dust in 2010, the mission encountered a host of obstacles and malfunctions.
Hayabusa-2 started its final approach towards Ryugu on June 3, and the asteroid is starting to come into focus. But it takes time to get a clear picture. In this image, taken on June 10 from 1,500 miles away, Ryugu is a blob just 5 or 6 pixels across.

By June 14, Hayabusa-2 was 700 km away, and JAXA researchers were finally able to see the asteroid’s rotation, which is in retrograde—rotating in the opposite direction in relation to the orbit of planets around the Sun. It was also rotating around its vertical axis.

As the spacecraft gets closer, more details emerge. Researchers found that Ryugu makes a full rotation every 7.5 hours, and found that it’s tapered shape resembled a spinning top. Mission Manager, Makoto Yoshikawa wrote “When I saw these images, I was surprised that Ryugu is very similar in shape to both the destination of the US OSIRIS-REx mission, asteroid Bennu, and also the target of the previously proposed MarcoPolo-R mission by Europe, asteroid 2008 EV5.” Yoshikawa writes. “So far, the asteroids we have explored have been different in shape, so Ryugu and Bennu could be the first time two similar-shaped asteroids have been examined. It will be interesting to clarify exactly what this similarity means scientifically.”
NASA’s OSIRIS-REx mission is scheduled to begin its approach to the asteroid Bennu in August of this year. Though they are on two separate timelines (OSIRIS-REx launched in 2016, and will spend a year surveying the asteroid), a main goal of both missions is to return a sample of an asteroid to Earth, a project scientists from each mission have been working closely together on to share information.
Images taken by Hayabusa-2 of Ryugu at distances between 220 km and 100 km.
In the most recent photo (seen at the top of this post) an even more detailed image comes into focus, an angular spinning shape pocketed with craters. Project Manager, Yuichi Tsuda compares the shape to the crystalline shape of fluorite, which he says in Japanese is known as the “firefly stone.” The resemblance is pretty uncanny.
Fluorite crystals can bear a striking resemblance to the asteroid Ryugu.
Ryugu is technically classified as a Potentially Hazardous Asteroid, but this does not mean you need to worry about it. As Ryan Mandelbaum points out at Gizmodo the ‘potentially hazardous’ designation does not mean that an asteroid is likely to hit Earth any time soon. It could, maybe at some point in the distant future, but it’s being tracked and closely monitored, so we’d have plenty of warning should its path eventually cross our own.
Researchers are interested in Ryugu because it is a C-class asteroid, one of the most common types of asteroids. By analyzing material from the space rock, scientists hope to get a better understanding of how bodies in the solar system, from asteroids to planets, developed.
Hayabusa-2 is scheduled to arrive at Ryugu on June 27, staying about 20 km above the asteroid’s surface. If all goes well, it will gather its first sample sometime between September and October.
Why this blind, catlike robot could transform search and rescue
Why this blind, catlike robot could transform search and rescue
No vision, no problem.

MIT's Cheetah 3 robot can climb stairs and step over obstacles without the help of cameras or visual sensors.
Massachusetts Institute of Technology
Scientists at MIT have created a four-legged robot that can climb debris-ridden stairs and leap almost three feet into the air, but the ominous-looking catlike bot — dubbed "Cheetah 3" — is intended not to hasten the robot apocalypse but to help bring about a new generation of first-responder robots.
As seen in a video released by the university, the 90-pound, retriever-sized robot navigates with touch sensors rather than cameras — a bit like the way humans feel their way when it's too dark to see.
“Cheetah 3 is designed to do versatile tasks such as power plant inspection, which involves various terrain conditions including stairs, curbs and obstacles on the ground,” Sangbae Kim, an associate professor of mechanical engineering at MIT and one of the robot's developers, said in a statement.
Kim plans to give Cheetah sight, but for early tests he wanted to keep the robot in the dark. "In order to be as agile as animals, including humans, we need to have a great blind controller first before relying on vision," he told NBC News MACH in an email.
Growing concern over fire risk involving Kia vehicles
Robin Murphy, a professor of computer science and engineering at Texas A&M University, sees big potential for search-and-rescue robots that maneuver with touch technology. Such bots could navigate in areas shrouded in darkness or obscured by airborne dust, said Murphy, who is not involved in the Cheetah project.
“It would be so great when that technology that they're showing matures and could be added to the robots that are the size of a shoebox,” she said of the MIT researchers' work. Small bots, of course, are able to get inside nooks and crannies too confined for humans — and relay information that human rescuers can then use to extricate victims of building collapses, for example.
“If you just start excavating, you could possibly trigger a secondary collapse that would kill the survivor or another survivor that you haven't found yet,” she said.
Search-and-rescue robots aren't new, but Cheetah 3 is one of many new bots now in development. Last fall, Honda unveiled a five-foot-tall robotthat can rotate its torso 180 degrees in order to climb steep stairs. Last February, the Italian Institute of Technology released a video showing its WALK-MAN humanoid bot wielding a fire extinguisher.
Next year, Kim and his team plan to equip Cheetah 3 with robotic arms that can be controlled by a human operator. They aim to have a commercial version of their bot ready in five years.

9 UFO Sightings No One Can Explain
9 UFO Sightings No One Can Explain
Krista Carothers
Lots of unidentified flying objects turn out to be weather balloons, clouds, or planes, but there are definitely sightings that can’t be explained away so easily.
Most UFOs don’t stay unidentified

UFO sightings often turn out to have very simple explanations, such as “aircraft, astronomical objects, rocket launches, balloons (escaped party balloons at sunset are particularly effective!), birds, insects, intensely bright squid lights used by Japanese fishermen, and so forth,” saysSeth Shostak, senior astronomer and fellow at theSETI Institute, which is dedicated to exploring the origins of life and intelligence in the universe. In 1973, before he became president, Jimmy Carter reported seeing a UFO, but it’s widely believed to have been the planet Venus. The debris found at Roswell Army Airfield in New Mexico in 1947 turns out to have been from a top-secret experimental spy balloon project that wasn’t declassified for almost half a century.
But not all can be explained away

In December 2017, the U.S. Department of Defense acknowledged to The New York Times that it had been running a program focused on investigating unidentified flying objects, or UFOs. The Advanced Aerospace Threat Identification Program (AATIP) received about $22 million in funding between 2007 and when it was shut down in 2012, according to the Pentagon. Two infrared videos were released with the articles that showed an encounter between Navy fighter jets and a UFO off the coast of California in 2004. Commander David Fravor, who was piloting one of the jets, told the paper that after a radio operator asked him to check out a mysterious aircraft, he flew to the specified location and saw the seawater churning below him. A whitish, oval-shaped aircraft was hovering above the water. “It accelerated like nothing I’ve ever seen,” Fravor told the Times, admitting that it made him feel “pretty weirded out.” Here are more science mysteries no one has figured out.
Unidentified, but not necessarily alien

Of course, just because there’s no explanation for an event does not mean it was a visit from extraterrestrial intelligence. There are plenty of phenomena that scientists don’t understand—they’re not even sure why ice is slippery. Shostak says he doesn’t know exactly what the AATIP videos show (though he has some ideas), but he’s not convinced that they indicate cosmic visitors: “There’s no explanation for about one-third of the murders in New York City,” he says. “Nonetheless, that doesn’t mean that they weren’t committed by people!”
Still, humans have been spotting mysterious objects in the sky for centuries, with cases increasing dramatically in the middle of the twentieth century, when aviation and the Cold War presumably made people extra wary of unexplained lights in the sky. Here are a few of the most notable examples of encounters that haven’t been solved yet.
China, 11th century

Around the year 1088, Shen Kuo, a well-respected poet and military tactician, wrote a book called Dream Pool Essays (named after his garden estate) that covered his scholarship in astronomy, mathematics, geology, zoology, botany and more. In the book, he describes what might be the first recorded UFO sighting; an object nicknamed “the Pearl” regularly appeared in the sky over Yangzhou province. Its door would open and very bright light would pour out. “The spectacle was like the rising sun, lighting up the distant sky and woods in red,” according to the text.
Mount Rainier, Washington, 1947

The flying-saucer era can be traced back to a sighting of a UFO that didn’t even look like a saucer. Amateur pilot Kenneth Arnold was flying over Washington on a clear June night when he spotted a flash of bluish light near Mount Rainier. Then he saw more—nine flashes in total. He said the lights moved around, like “the tail of a Chinese kite,” according to a 1967 book about the incident by Ted Bloecher. Arnold at first thought they were jets, then maybe geese, and then he ruled both of those out and did not know what he was looking at. Later, when he described the sight to reporters, he said something about how the lights moved “like a saucer if you skip it across the water.”
Socorro, New Mexico, 1964

By the mid-1960s, UFOs were being investigated by the U.S. government through Project Blue Book, and space alien plots were common in movies and TV shows; TheOuter Limits series started in 1963. When Socorro, New Mexico, police officer Lonnie Zamora heard a loud roaring sound and saw a flame in the sky, he abandoned the speeding car he’d been chasing to check it out. He found a round object in a canyon and saw two figures in white near it, but as he got closer, the object flew away. Investigators from Project Blue Book apparently believed Zamora wasn’t making up the story and weren’t able to come up with a clear explanation (despite the event’s proximity to the White Sands Missile Range). They classified the case as “unidentified.” Find out all the secrets about Area 51 the US government won’t tell you.
Finland, 1969

A group of fighter pilots on a navigation flight saw seven objects shaped like disks or balloons hovering about 5,000 feet in the air over a field. As the jets approached, the objects flew off at what the air force pilots called astonishing speed, according to an article in the Finnish Defense Forces’ magazine, Ruotuväki. The incident is the only UFO encounter acknowledged by the country’s air force.
France, 1981

When the French UFO investigation division (called GEIPAN) released its records to the public in 2007, its website crashed from too many users. One of its most famous unexplained cases happened near the southern village of Trans-en-Provence, where a resident said an 8-foot oval-shaped craft landed on his property and then quickly took off again. It left behind marks, which GEIPAN confirmed appeared to have been made by a heavy object.

Several drivers actually pulled off the highway to get a better look at what they described as a group of golden-orange lights moving quietly overhead near the Arthur Kill Waterway. One of the witnesses was a lieutenant from the nearby Carteret Police Department. Air traffic controllers couldn’t come up with any explanations, and the National Weather Service didn’t have any ideas either. Here are more everyday mysteries scientists can’t explain.
Chicago O’Hare International Airport, 2006

On a cold November afternoon, pilots, ramp workers, mechanics, and United Airlines employees working at or near Concourse C at O’Hare saw what looked like a very unusual aircraft hovering above the airport. All described it as a shiny gray disc, according to the Chicago Tribune, and some thought it was spinning. After several minutes, it shot silently upward and punched a hole in the cloud above. Unfortunately, nobody got a photo or video, and the Federal Aviation Administration said it hadn’t caught anything on its radar systems.
Arizona, 2018

Two commercial pilots—one in a Learjet and the other flying an American Airlines plane—both reported seeing an object pass two or three thousand feet over them in Arizona airspace in February. The Federal Aviation Administration released the radio exchanges between the pilots and the air traffic controller and confirmed that it did not know of any other aircraft that was supposed to be in the area at the time, according to Fortune. You’ll also want to check out the 13 weirdest things archaeologists have ever found.
Civilian reports

The SETI Institute’s Seth Shostak says he’s received thousands of reports of sightings that witnesses can’t explain. “I hear from members of the public every day who have seen or experienced something they attribute to alien presence,” he says. But he’s not convinced that aliens are invading, and he doesn’t think we should worry. “Keep in mind that there are more than 3,000 satellites in orbit making images of the Earth—many at very high resolution. If we were really being buzzed by extraterrestrial craft, they would be seen by satellites all the time.” Read more about the UFO myths scientists want you to stop believing.
WETENSCHAP & PLANEETHet was groot nieuws toen de Marsrover Curiosity van de NASA vorige maand meldde dat hij organische moleculen op Mars gevonden had. In de late jaren 70 had de ruimtevaartorganisatie al gezocht naar sporen van leven op de rode planeet, maar zonder resultaat. Een nieuwe studie zegt nu dat de NASA de organische moleculen ook toen in handen had, maar ze verbrandde. Per ongeluk.
Het was begin vorige maand dat de ontdekking van Curiosity wereldnieuws was. De rover – die al zes jaar rondzwerft op Mars – had organische moleculen gevonden in afzettingsgesteenten van 3 miljard jaar oud. En dat kon erop wijzen dat er ooit leven was op Mars.
Curiosity was niet de eerste rover van de NASA die er op zoek ging naar sporen van leven. In de late jaren 70 stuurde de ruimtevaartorganisatie al eens twee Vikingrobots naar Mars om organische (lees: uit koolstof opgebouwde) moleculen te vinden. De missie moest een makkie worden, want de oppervlakte van de rode planeet werd constant onder vuur genomen door kleine koolstofrijke meteorieten. Sporen van koolstof vinden kon toch geen probleem zijn?
Dat was het wél. Na vijf jaar zoeken had geen van beide Vikings ook maar iets bovengehaald. Een nieuwe studie – die gepubliceerd werd in het wetenschappelijke tijdschrift Journal of Geophysical Research: Planets – zou daar nu een verklaring voor hebben. De koolstof was er de hele tijd, maar de Vikings zouden alle bewijsmateriaal per ongeluk verbrand hebben.
“Er werden in totaal vier stalen geanalyseerd, elk verschillende keren, door ze snel op te warmen tot een van vier temperaturen”, aldus wetenschappers van het Ames Research Center van NASA en het Atmosphere, Media, Spatial Observations Laboratory in Frankrijk die het onderzoek uitvoerden.
500 graden Celsius
De Vikings verhitten hun bodemstalen tot een maximumtemperatuur van 500 graden Celsius om vluchtige organische componenten die er mogelijk in zaten, vrij te laten komen. Die moesten dan waarneembaar zijn in de verdampte bodem. Maar waarom werd er niets gevonden?
Volgens de onderzoekers van de nieuwe studie kan er nog iets anders gespeeld hebben. Er zou immers nog iets anders in de bodem gezeten hebben, waarop de NASA niet gerekend had. In 2008 ontdekte de Marsrover Phoenix een ongewone stof toen hij door de bodem ging aan de noordpool van de planeet: perchloraat. Dat is een extreem brandbare stof, die op Aarde gebruikt wordt om raketbrandstof te maken en vuurwerk sneller te doen branden. Als die stof op Mars aanwezig was, zou de verhitting in de oven van de Vikings het perchloraat hebben doen ontbranden, waardoor elk spoor van mogelijke organische moleculen meteen vernietigd was.
Bewijs
Als die these klopte, moest er bewijs zijn in de as. Als koolstof en perchloraat samen branden, ontstaat de molecule chloorbenzeen. Toeval wilde dat Curiosity daar sporen van vond tijdens een missie in 2013. Om zeker te zijn, gingen de onderzoekers ook terug naar de Vikings zelf.
Ze doorzochten de data van de robots naar sporen van chloorbenzeen en vonden die. Ze zaten in stalen die door Viking 2 waren genomen en daarop kwamen de onderzoekers tot de conclusie dat de robot ooit organisch materiaal in zijn hand moet hebben gehad, maar het per ongeluk zelf vernietigde.

RUSSIA DESTROYS EXTRATERRESTRIAL DRONES
NASA zou voor het eerst glimp opgevangen kunnen hebben van ster die planeet verslindt - HLN.be
Koen Van De Sype
WETENSCHAP & PLANEET De NASA zou wel eens voor de allereerste keer een glimp opgevangen kunnen hebben van een jonge ster die een babyplaneet verslindt. De ster in kwestie – RW Aur A – is een paar miljoen jaar oud en bevindt zich op 450 lichtjaar van onze Aarde. Als de waarneming bevestigd wordt, zou het om een buitengewone observatie gaan. Ze kan astronomen meer inzicht geven in de processen rond de ontwikkeling, de vernietiging en het overleven van planeten.
De waarneming werd gedaan door het Chandra X-Ray Observatory van ruimtevaartorganisatie NASA. RW Aur A – dat zich in ruimtevaarttermen met zijn 4.275 biljoen kilometer niet zo heel ver van onze Aarde bevindt – wordt al sinds de jaren 30 van vorige eeuw bestudeerd en astronomen braken er zich het hoofd over waarom het optische licht van de ster zo wisselt met de tijd. Om de paar decennia neemt het licht ongeveer een maand af, waarna het terugkeert.
In 2011 veranderde er echter iets. De ster dimde vaker en voor langere periodes: de eerste keer voor 6 maanden, in 2014 zelfs voor 2 jaar en in januari vorig jaar werd het opnieuw donkerder.
Om een tip van de sluier op te lichten werd Chandra ingeschakeld. Meer bepaald tijdens een optisch heldere periode in 2013 en duistere periodes in 2015 en 2017, toen ook een vermindering van X-stralen werd vastgesteld. Omdat die X-stralen uit de hete buitenste atmosfeer van de ster afkomstig zijn, konden schommelingen in de intensiteit iets meer zeggen over de dichtheid en de samenstellingen van het absorberende materiaal rond de ster.
Het team ontdekte dat de donkere periodes veroorzaakt werden door een dicht gas dat het licht van de ster verduisterde. In 2017 werden er heel veel ijzeratomen uitgestoten, wat aangaf dat de ster minstens 10 keer meer ijzer bevatte dan in de heldere periode in 2013.
Dat ijzer zou ontstaan zijn door een botsing van twee jonge planetaire lichamen, waarvan er zeker eentje groot genoeg was om een planeet te zijn. Puin – met daarin ijzer – van de lichamen viel op de ster, wat een dikke sluier van stof en gas veroorzaakte, dat het licht van de ster tijdelijk dimde.
Interpretatie
“Computersimulaties voorspellen al langer dat planeten op een jonge ster kunnen botsen, maar we hebben dat nog nooit kunnen observeren”, aldus Hans Moritz Guenther van het Kavli Institute for Astrophysics and Space Research van het Massachusetts Institute of Technology (MIT). Hij leidde de studie. “Als onze interpretatie van de data correct is, zou dit de eerste keer zijn dat we een directe waarneming kunnen doen van een jonge ster die een of meerder planeten verslindt.”
De vorige keren dat het licht van de ster – die ongeveer dezelfde massa heeft als onze relatief oude zon – gedimd werd, zou er iets soortgelijks gebeurd kunnen zijn: botsingen van twee planetaire lichamen of grote resten van eerdere botsingen die tegen elkaar aan knalden en nog verder in kleine stukken gebroken werden.
De resultaten van het onderzoek werden gepubliceerd in het wetenschappelijke tijdschrift Astronomical Journal.

Complotdenkers zijn niet gek. Socioloog legt uit waarom we nog veel van hen kunnen leren
Complotdenkers zijn niet gek. Socioloog legt uit waarom we nog veel van hen kunnen leren
Het merendeel van de complotdenkers is niet gek. En als we hen serieus nemen, kunnen we veel van hen leren. Dat stelt socioloog Jaron Harambam, die zijn proefschrift schreef over complottheorieën.
Hij kwam via de films van Zeitgeist in aanraking met de wereld van de samenzweringstheorieën.
“Daar ging mijn wereld echt van op zijn kop staan,” vertelt hij aan De Correspondent. “Hier werd verteld hoe ons geldsysteem werkt, hoe geld eigenlijk uit het niets wordt gecreëerd.”
“Ik las daar niets over in de reguliere media,” vervolgt hij.
Gelijk
Harambam stoort zich aan het dominante denken van veel wetenschappers en media over complotdenkers.
“Ze pikken een paar figuren uit die complot-scene die het meest extreem zijn en gaan er vervolgens van uit dat alle complotdenkers zo zijn,” zegt hij.
Hij wijst erop dat er complotdenkers zijn die gedegen onderzoek doen en veel dieper graven dan sommige wetenschappers.
“En soms hebben complotdenkers gewoon gelijk, maar krijgen ze dat gelijk pas later,” klinkt het.
Genoeg vragen
Er zijn rond 9/11 bijvoorbeeld nog genoeg vragen over de toedracht en de officiële lezing die nog niet beantwoord zijn.
“Deze complotdenker heeft zijn verhaal niet dichtgetimmerd, maar doet open onderzoek naar die vragen,” zegt hij.
“Hij doet alleen beweringen die hij kan staven en documenteert zijn bevindingen heel secuur,” voegt hij toe.
Totaal onduidelijk
Volgens hem zijn complotdenkers niet de enigen die worstelen met de waarheid. Over de recente gifgasaanval in het Syrische Douma zegt hij: “Wat daar werkelijk gebeurd is, is door allerlei propaganda van verschillende partijen totaal onduidelijk.”
Sommige wetenschappers, politici en media willen ons doen geloven dat er maar één waarheid is, maar die bestaat niet, aldus Harambam.
Mysterious sarcophagus to be opened in two days, Egypt’s MOA says
Mysterious sarcophagus to be opened in two days, Egypt’s MOA says
Egypt’s Ministry of Antiquities (MOA) has finally decided to open a mysterious sarcophagus uncovered in Alexandria within the next two days, according to Waad Allah Abu al-Ela, head of the MOA’s project sector.
On July 1 a large black granite sarcophagus was accidentally unearthed in an Alexandrian construction site. It was found at a depth of 5 meters and dates well over 2,000 years ago, likely at the Ptolemaic era between 305 BC and 30 BC.
A man’s head sculpted from Alabaster was also found, likely belonging to the owner of the tomb.
Abu al-Ela said that they will use thick pipes to raise the sarcophagus lid until they can see inside. Once something was found, a specialized restoration team will immediately take over, transferring the contents into an Alexandria museum storage to quickly start restoration procedures.
“If nothing was found inside the sarcophagus and we did not find any inscriptions on the coffin’s body, we will keep it in place until it can be lifted later,” he said.
Speculation ran wild across the globe following the discovery as the unique specifications of the tomb has prompted some experts to conclude the sarcophagus belongs to none other than Alexander the Great, who’s tomb has yet to be uncovered. Born in 356 BC and living until 323 BC, Alexander was one of the world’s greatest conquerors and ruled the ancient Greek kingdom of Macedon.
The MOA considers this the biggest coffin unearthed yet from Alexandria, as it weights around 20 to 30 tons, with dimensions that are 185 cm tall, 265 cm long and 165 cm wide.
As if that wasn’t enough, Ayman Ashmawy, an MOA official stated that to their surprise the layer of mortar between the coffin’s lid and the body was undamaged, meaning it had not been opened since it was buried 2000 years ago, an incredible rare occasion.
However Abu al-Ela denounced the speculation, stating that the tomb is far too poor and weak to belong to someone like Alexander the Great. He also stated that the weight of the sarcophagus is not abnormal, as coffins weighting more than 90 tons have been found in the past.
Mustafa Waziri, Secretary General of the Supreme Council of Antiquities supported Abu Ela’s doubt, and stated that while the coffin might not be suitable for Alexander, it could still belong to an ancient Egyptian noble.
Mysterieuze zwarte sarcofaag uit Alexandrië wordt na 2000 jaar opengemaakt. Wat gaan archeologen aantreffen?
Mysterieuze zwarte sarcofaag uit Alexandrië wordt na 2000 jaar opengemaakt. Wat gaan archeologen aantreffen?
De mysterieuze sarcofaag die onlangs in Alexandrië is ontdekt, wordt vandaag of morgen geopend. Dat heeft het Egyptische ministerie van Oudheden besloten.
Begin deze maand werd bij toeval een gigantische zwarte sarcofaag gevonden in een bouwput in Alexandrië.
De graftombe bevond zich op een diepte van vijf meter en is ruim 2000 jaar oud. Er werd ook een albasten hoofd van een man gevonden, waarschijnlijk van de eigenaar van de tombe.
Alexander de Grote
Met behulp van zware pijpen zal het deksel van de sarcofaag worden gehaald. De eventuele inhoud van de tombe wordt vervolgens overgebracht naar een museum in Alexandrië.
Na de ontdekking werd op internet druk gespeculeerd over de vondst. Sommige experts claimden dat de sarcofaag toebehoort aan niemand minder dan Alexander de Grote, wiens tombe nog altijd niet is ontdekt.
Het gaat om de grootste grafkist die ooit in Alexandrië is opgegraven. De tombe weegt 20 tot 30 ton en is ruim 2,5 meter lang.
Extreem zeldzaam
Opvallend genoeg is de laag cement tussen het deksel en de grafkist onbeschadigd, wat betekent dat de tombe in ruim 2000 jaar niet geopend is. Dat is extreem zeldzaam.
Volgens het ministerie gaat het niet om de tombe van Alexander de Grote. In het verleden zijn grafkisten van meer dan 90 ton gevonden.
