Kan een afbeelding zijn van hond

Dit is ons nieuw hondje Kira, een kruising van een waterhond en een Podenko. Ze is sinds 7 februari 2024 bij ons en druk bezig ons hart te veroveren. Het is een lief, aanhankelijk hondje, dat zich op een week snel aan ons heeft aangepast. Ze is heel vinnig en nieuwsgierig, een heel ander hondje dan Noleke.

This is our new dog Kira, a cross between a water dog and a Podenko. She has been with us since February 7, 2024 and is busy winning our hearts. She is a sweet, affectionate dog who quickly adapted to us within a week. She is very quick and curious, a very different dog than Noleke.

    Als we het hebben over invasieve uitheemse soorten, bedoelen we dieren die zijn geïntroduceerd in een ecosysteem waar ze geen deel van uitmaken, maar die daardoor een bedreiging vormen voor de lokale biodiversiteit. Er zijn veel voorbeelden, zoals de blauwe krab en de Louisiana rivierkreeft, of zoogdieren die door kolonisten naar verschillende delen van de wereld zijn gebracht. Heel anders is het geval van de gigantische hagedissen die onlangs in Florida zijn gespot, reptielen die vreemd zijn aan het lokale ecosysteem maar een potentieel gevaar vormen voor dieren en mensen. Laten we eens kijken wat het zijn en waarom ze in Florida voorkomen.

    Gigantische hagedissen in Florida: een steeds vaker voorkomende waarneming

    Over waarnemingen van reuzenhagedissen in Florida wordt met min of meer regelmatige tussenpozen gesproken, maar de laatste jaren steeds vaker. Een van de meest recente incidenten werd gedocumenteerd door een vrouw genaamd Renee Aland, die video's en foto's deelde van een waarneming op een paar meter afstand.

    Op de beelden is een groot reptiel van bijna twee meter lang te zien dat bekend lijkt te zijn met de verharde wegen van Florida. Renee vertelt hoe het in een kanaal dook en kort daarna weer boven water kwam, zonder acht te slaan op de vrouw die filmde met haar mobiele telefoon en ondertussen haar dochter aanspoorde om niet uit de auto te stappen. Nadat ze de video en de beelden had gedeeld op sociale media, stuurde de vrouw de documentatie ook naar de Florida Fish and Wildlife Conservation Commission, die de waarneming zal afhandelen en het dier mogelijk zal vangen. Maar wat was het precies?

    Wat zijn de gigantische hagedissen die in Florida werden gespot?

    Volgens functionarissen van het FFWCC, en afgaande op Renee's beelden, zijn de reuzenhagedissen die in Florida zijn gezien Aziatische watervaranen, wetenschappelijke naam Varanus salvator. Het gaat om een reuzenhagedis die zelfs langer kan worden dan twee meter en iets kleiner is dan de Komodovaraan, een van zijn naaste verwanten. Aziatische watervaranen worden dan ook vaak verward met Komodovaranen, waar ze fysiek op lijken.

    Net als Komodovaranen kunnen watervaranen zich voeden met grotere prooien en bezitten ze gifklieren in hun onderkaak. In de praktijk bijten ze hun prooi en kunnen hem dan zelfs uren of dagen volgen, wachtend tot het gif effect heeft. Deze reuzenhagedissen komen oorspronkelijk uit Zuidoost-Azië, maar waarom bevinden ze zich dan in Florida?

    Waarom zijn er varanen in Florida?

    Dat er Komodovaranen of watervaranen in Florida zijn is niet verrassend, omdat ze misschien te gast zijn in een dierentuin en dus geen invasieve uitheemse soorten zijn. Het probleem is een ander: watervaranen worden vaak geïntroduceerd als exotische huisdieren, en slagen er misschien in om uit gevangenschap te ontsnappen of worden vrijgelaten door hun eigenaars. Daardoor worden het uitheemse en invasieve dieren die de biodiversiteit van het gebied in gevaar kunnen brengen.

    Dit is een wijdverspreid maar weinig besproken probleem, dat mogelijk een probleem vormt voor inheemse soorten en hun evenwicht. Aan de andere kant zijn Aziatische watervaranen echte reuzenhagedissen: ze vormen misschien geen echt gevaar, maar ze moeten zeker niet onderschat worden.

    Discovery: it wasn't a comet that wiped out the dinosaurs, and it didn't come from Jupiter

    Story by Cédric DEPOND

    About 66 million years ago, a cataclysmic event marked the end of the dinosaur era. This episode is linked to the impact of a giant asteroid in the Chicxulub region of Mexico. Until now, the exact nature and origin of this celestial body remained subject to debate.

    A new study published in Science sheds light on these mysteries by revealing that this asteroid originated from the outer Solar System, beyond Jupiter, and not from a comet as some had supposed.

    Illustration image Pixabay

    Researchers employed an innovative method to analyze samples of ancient sediments. These contain ruthenium, a chemical element absent from terrestrial rocks. By comparing the isotopes of ruthenium in the samples with those from different classes of meteorites, they determined that the asteroid that struck Earth was a carbonaceous type (type C). This indicates it formed beyond Jupiter's orbit, in a region where asteroids contain more carbon and volatile elements.

    This discovery challenges the hypothesis put forward in 2021 by two Harvard researchers, who proposed that the Chicxulub impactor was a long-period comet. According to their theory, the comet was fragmented by the Sun's gravitational influence before a fragment collided with Earth. However, the new data confirm that the celestial object was indeed a carbonaceous asteroid, thus refuting the comet idea.

    Ruthenium played a key role in this identification. In fact, the isotopes of this element allow for distinguishing type C asteroids, formed in the outer Solar System, from type S asteroids, which are more common and originate from the inner Solar System. The fact that the Chicxulub asteroid is type C is particularly significant, as most meteorites found on Earth are type S, formed in regions closer to the Sun.

    The implications of this discovery extend beyond dinosaur history. According to Mario Fischer-Gödde, a geochemist at the University of Cologne and lead author of the study, better understanding the nature of asteroids that have impacted Earth over time could provide clues about the origin of water on our planet. He also suggests that if other mass extinctions were caused by type C asteroids, it would be essential to closely monitor this type of celestial object in the future, as they could pose a significant threat to life on Earth.

    Unraveling the Indian Ocean's Mysterious Gravity Hole

    Story by Bruno Pugh
     

    Unraveling the Indian Ocean's Mysterious Gravity Hole

    For decades, a massive anomaly sprawling across 1.2 million square miles on the Indian Ocean floor has baffled scientists. This phenomenon, known as the “gravity hole,” has sparked endless debate and curiosity. Read on as we uncover this mystery, officially named the Indian Ocean Geoid Low.

    The Indian Ocean’s Gravity Anomaly

    The Indian Ocean’s Gravity Anomaly
    So, what’s the deal with this vast region of the Indian Ocean that sits up to 106 meters below the global average sea level? It turns out there’s a significant dip in Earth’s gravity here. This gravitational anomaly has puzzled scientists for years, but recent studies are shedding light on its origins and linking it to deep geological processes.

    Understanding the Geoid Low

    © Paul Wilson Images/Facebook

    Understanding the Geoid Low
    Geologists have a term for this “hole”—a geoid low, where Earth’s gravity is weaker than average. It might sound alarming, but it’s just a natural part of our planet’s gravitational landscape. Recent research suggests that molten rock plumes rising from deep beneath Africa are responsible for this phenomenon; these plumes are at the edge of an ancient sea bed.

    Earth’s Shape and Gravitational Variation

    Earth’s Shape and Gravitational Variation
    Ideally, Earth would have uniform gravity, but it’s not a perfect sphere. It’s flatter at the poles and bulges at the equator, causing variations in gravity. Different regions exert varying gravitational pulls based on the crust, mantle, and core mass distribution. Such complexity contributes to gravitational anomalies like the low geoid of the Indian Ocean.

    The Potsdam Gravity Potato
    To visualize these gravitational tugs, scientists use gravity measurements from sensors and satellites to create models like the “Potsdam gravity potato.” The model highlights Earth’s gravitational highs and lows, helping scientists understand the mass distribution beneath the surface. It’s like taking off each layer of an onion, discovering more with every peel.

    Discovery and Confirmation of the IOGL

    Discovery and Confirmation of the IOGL
    The Indian Ocean Geoid Low (IOGL) was discovered by Dutch geophysicist Felix Andries Vening Meinesz in 1948 during a ship-based gravity survey. Since then, subsequent shipboard expeditions and satellite measurements have confirmed its presence. This IOGL is the planet’s most prominent gravitational anomaly, covering over three million square kilometers.

    Investigating the Origins

    Investigating the Origins
    Researchers Attreyee Ghosh and Debanjan Pal compared various computer models of the region’s formation over the past 140 million years. Each model used different variables for the convection of molten material within the mantle. Their goal? To pinpoint the cause of the IOGL. Their findings point to a distinctive mantle structure influenced by ancient geological events.

    The Role of the Mantle and the African Blob

    © The Role of the Mantle and the African Blob

    The Role of the Mantle and the African Blob
    The study suggests that the IOGL is due to a unique mantle structure combined with an adjacent disturbance under Africa known as the “African blob.” This large low-shear velocity province (LLSVP) consists of hot, low-density material, thought to be remnants from ancient seafloor slabs, which influence the region’s gravitational characteristics.

    Connection to the Tethys Ocean

    © Encyclopedia of Science/Wikipedia

    Connection to the Tethys Ocean
    Geologists believe Tethyan slabs, remnants of an ancient seafloor from the Tethys Ocean, form the African blob. Over 200 million years ago, the Tethys Ocean existed between the supercontinents Laurasia and Gondwana. As India moved northward, it created the Indian Ocean and left behind these geological traces.

    Evolution and Persistence of the IOGL

    Evolution and Persistence of the IOGL
    Around 20 million years ago, the geoid low probably formed its current shape as plumes began spreading through the upper mantle. The mantle material flow from the African blob sustains this anomaly. As long as these flows continue, the geoid low will persist.

    Future Implications

    Future Implications
    The IOGL will eventually dissipate when temperature anomalies cause it to move, which could take many millions of years. Studying this geoid low provides valuable insights into Earth’s internal processes and the dynamic nature of its mantle.

    What would happen if humans dried out the Mediterranean sea, turning it into a giant salt lake? Would its wildlife survive, and if so, how long would it take to recover?

    These may seem like wildly theoretical questions, but not for Herman Sörgel, a Bavarian architect who dedicated much of his life to this exact project: building a giant dam across the Strait of Gibraltar, letting the Mediterranean dry up, and colonising the land reclaimed from the sea.

    Sörgel organised lectures and documentaries and raised funds until the 1950s for a project which, he believed, would promote cooperation between Africa and Europe, and power both continents through gigantic hydroelectric megaprojects.

    What he did not know was that his dream had already come true at the end of the Miocene era, 5.5 million years ago, as a simple result of natural forces.

    When the Mediterranean disappeared

    Since the 1970s, several generations of marine geologists and geophysicists have confirmed the existence of a one to three kilometre thick layer of salt buried throughout most of the deeper parts of the Mediterranean Sea.

    This is almost a million cubic kilometres of salt that testify to a brief period when the Mediterranean was isolated from the rest of the world’s oceans – brief in the geological sense, as the episode lasted about 190,000 years

    The culprit was not, of course, an eccentric German architect, but plate tectonics. The Mediterranean basin, trapped between two continents that today continue to move closer by up to two centimetres every year, was cut off from the Atlantic. Its waters quickly evaporated due to the region’s arid climate, leaving behind vast amounts of salt.

    This episode, known as the Messinian salinity crisis (the Messinian being the last period of the Miocene), is the biggest extinction event suffered by the Earth since the meteorite that wiped out the flightless dinosaurs and ended the Mesozoic era 65 million years ago.

    As a result, no geoengineering experiments are needed to answer our initial question: how resilient is marine life in the face of an environmental crisis of this magnitude?

    The answer has just been published in the journal Science, in a study led by Konstantina Agiadi of the University of Vienna in collaboration with the Spanish National Research Council and 28 other scientists from 25 European institutes.

    After gathering all Mediterranean fossil data from between 12 and 3.6 million years ago, the results suggest that native marine life was virtually extinct when the Mediterranean was cut off, and that subsequent recolonisation by Atlantic species gave rise to a Mediterranean fauna more similar to the one we find there today.

    Native, extinct and migrant species

    By statistically analysing information from more than 750 scientific papers, we were able to document 22,932 presences of a total of 4,897 marine species living in the Mediterranean. Before the crisis, 779 species could be considered endemic species (i.e. documented only in the Mediterranean). Of those, only 86 were still present after the salinity crisis. All the tropical corals that were abundant in the Mediterranean before this cataclysmic environmental change disappeared.

    However, some apparently endemic sardine species managed to survive. The sirenian, a sea mammal related to today’s manatees and dugongs (also known as sea cows) also survived.

    Because fossil records are limited and fragmented we cannot be certain that these species were all endemic, or that they would not have survived outside the Mediterranean, hence the value of basing our study on statistics from a large number of species. But for those that were endemic, where did they manage to survive, and what refuges did they find to avoid the radical increase in salt levels and temperature?

    These questions remain unanswered, but we have been able to establish that changes in populations are the result of replacement by Atlantic species after the Mediterranean’s re-flooding, rather than rapid adaptation to the new hypersaline environment. In other words, life did not have enough time to adapt, and the extinct species were replaced by Atlantic species that migrated into the Mediterranean.

    Several iconic species, such as the great white shark and the dolphin, only appeared in the Mediterranean after the crisis. Even more interestingly, the current richness of fauna in the western Mediterranean only came after the re-flooding – previously, the eastern Mediterranean (Ionian and Levantine Seas) had possessed a higher number of different species.

    Lessons on mass extinction

    The impact of the Mediterranean’s isolation on its fauna and flora was catastrophic, destroying most of its ecosystems. Another significant finding from our research is that it took more than 1.7 million years for species numbers to recover. This slow recovery of the richness of Mediterranean ecosystems provides the first detailed quantification of how wildlife responds to an extinction event of this magnitude.

    The Mediterranean’s biodiversity today is very high thanks to the presence of numerous endemic species. Our results suggest that this was also the case six million years ago, but that the vast majority of these endemic species disappeared when it was cut off from the Atlantic.

    Perhaps another lesson learned from this study is that, however tempting it may be to believe that geoengineering projects can allow us to maintain our current rate of emissions and ecosystem destruction, the Earth’s geological past will reveal more than any experiment.

    When the Mediterranean was reconnected to the Atlantic, it was repopulated by the huge reserve of species in the world’s oceans, yet it still took millions of years for the Mediterranean’s ecosystems to recover in terms of richness. No one knows yet how long it will take for marine life to recover from the kind of global-scale change that is currently underway.

    Being Stranded In Space Could Upend Starliner Astronauts’ Perception of Time

    Waiting slows our perception of time.

    by Ruth OgdenDaniel Eduardo Vigo and The Conversation
    Butch Wilmore and Suni Williams onboard the space station.

    Two astronauts marooned in space may sound like the plot of a Hollywood blockbuster, but for two NASA crew members, it is now a reality. Commander Barry Wilmore and pilot Sunita Williams are currently in limbo on the International Space Station (ISS).

    They arrived in the Boeing Starliner spacecraft — the first test of the spaceship with astronauts. Wilmore and Williams were supposed to stay on the ISS for around eight days and return on the same spacecraft. But there is now debate about the safety of Starliner after it experienced helium leaks and thruster problems on its way to the ISS.

    In the coming days, NASA and Boeing may decide to clear Starliner to carry the astronauts back to Earth. This means their stay might not last too much longer. But if officials decide against Starliner, the astronauts face waiting an additional six months in orbit before returning. So how do astronauts cope with a potential six-month wait for a lift home?

    Waiting for things is difficult at the best of times. Under normal circumstances, it is frustrating, stressful and anxiety-provoking. But in extreme situations, with high stakes, waiting can be purgatory.

    Part of the reason that waiting is difficult is that it distorts our sense of time. Think of the last time you were waiting for a delayed train, test results or a text from a potential new partner. Did it fly by or drag? For most people, time spent waiting crawls at a glacial pace. As a result, delays and periods of anticipation often feel much longer than they actually are.

    Waiting slows our perception of time because it changes the amount of time that we spend thinking about time. During normal daily life, we often ignore time, and our brains have a limited capacity. If time isn’t important, we simply don’t think about it, and this helps it to pass quickly.

    When we are waiting, our desire to know when the wait is over increases how much we think about time. This “clock watching” can make the minutes and hours feel like they are passing at a snail’s pace. Stress, discomfort and pain exacerbate this effect, meaning that waiting in difficult situations can seem even longer.

    Waiting also slows our perception of time because it is what we do and how we feel. Normal life is busy and full of ever-changing activities and interactions. The sudden need to wait halts the flow of life, often leaving us with nothing else to do, thus increasing levels of boredom and frustration.

    In general, time filled with activity passes more quickly. We all got a taste of this during COVID lockdowns. When we were stuck inside, unable to see friends and engage in normal daily activities, the loss of routine and distractions caused time to drag for many.

    For the astronauts stuck on the ISS, anxiety about when they will return, limited opportunities for activities and fewer opportunities to contact friends and families combine to make their wait to return home feel significantly longer than six months — if it should come to that.

    However, as academics who research the effects of time on human psychology and biology, our ongoing work with crew members at research stations in Antarctica aims to shed light on whether waiting in extreme environments is different to waiting during normal daily life.

    A year in Antarctica

    While being stuck for six months on the ISS may sound like many people’s worst nightmare, it is not uncommon for scientists to spend long periods isolated and confined in extreme environments. Every year, organizations such as the Instituto Antártico Argentino (which uses the Belgrano II Antarctic station), the French Polar Institute and the Italian Antarctic Programme, in cooperation with the European Space Agency (which all use Antarctica’s Concordia station), send crews of people for up to 16 months to conduct research on the frozen continent.

    During the March to October polar winter, teams spend six months in near darkness – and from May to August, in complete darkness – facing outside temperatures of up to -60C, wind speeds of 160 km/h (100 mph) and storms which prevent almost all outdoor activity. Limited internet coverage can also prevent constant communication with the outside world.

    For the last year, we have researched how life in Antarctica influences people’s experience of time. Each month, we asked crew members how time felt like it was passing in comparison to before their mission. Trapped on base, with limited contact with the outside world, you might expect time to drag. However, our results suggest the opposite may be true.

    Analysis of crew members’ experiences indicated that being constantly busy with complex tasks such as scientific research helped the time to pass swiftly, according to 80% of crew responses. Only 3% of responses indicated that time actually dragged, and these reports occurred when nights were long, and there was little to do.

    These experiences may provide hope for those stuck on the ISS. Like life in an Antarctic station, these NASA astronauts have busy and mentally demanding lives. These factors may help time to pass quickly.

    However, a key factor of their wait may be their ability to tolerate the uncertainty of when they will return. Wilmore and Williams will spend their time in a space equivalent to the inside of a Boeing 747 plane. However, better information about “when” things will happen and “why” delays are being incurred can help people tolerate waiting and reduce its impact on their wellbeing.

    The Webb Telescope Just Identified 6 Giant Gaseous Planets That Are More Massive Than Jupiter

    And these strange worlds may be a lot more common than we thought.

    by Kiona Smith

    STSCI

    Rogue planets may be more common than we thought, and they may form alone in the void in the same way stars do, suggests a recent study.

    We think we know how the universe is structured: Moons orbit planets, and planets orbit stars. But rogue planets don’t play by the rules; they drift alone through the darkness, not bound to a star’s gravity. And these lonely rebel worlds may make up about 10 percent of celestial objects, not just rare flukes of nature.

    The James Webb Space Telescope (JWST) peered into a nearby star cluster and found a handful of rogue gas giants — including one with its own disk of dust swirling around it. The results suggests that rogue planets may not only be worlds that got kicked out of their star systems, but worlds that coalesce out of clouds of interstellar gas in the same way stars do — just smaller.

    Johns Hopkins University astrophysicist Adam Langeveld and his colleagues published their work in The Astronomical Journal.

    photo of a nebula and stars in space

    This is JWST’s latest image of NGC 1333, a stellar cluster about 1,000 light years away, where new stars — and new rogue planets — are still being born.

    STScI

    Lonely Planets Club

    Langeveld and his colleagues surveyed a cluster of stars called NGC 1333, which exists 1,000 light years away in the constellation Perseus, with JWST’s Near Infrared Imager and Slitless Spectrograph (NIRISS) instrument. They found six gas giants — each between five and 10 times more massive than Jupiter — drifting through space on their own, not orbiting a star. One of these lonely worlds even had a disk of dust orbiting it, as if in the process of forming its own little family of planets (or moons). And based on their observations, Langeveld and his colleagues say rogue planets, once thought to be rare flukes of nature, might make up about 10 percent of the objects in the cluster.

    We know that stars form when dense clumps of gas and dust in clouds called nebulae collapse under their own gravity, creating enough heat and pressure at their centers to kickstart nuclear fusion. And we know that sometimes, a clump of material can form an object that’s just on the threshold of being able to start burning as a star, but doesn’t have quite enough mass to get there: a brown dwarf. But astronomers weren’t sure whether even smaller objects, like giant gas planets, could form the same way.

    The team of astrophysicists used JWST “to search for the faintest members of a young star cluster, seeking to address a fundamental question in astronomy: how light an object can form like a star?” says Johns Hopkins University astrophysicist Ray Jayawardhana, the senior author of the recent paper, in a recent statement. “It turns out the smallest free-floating objects that form like stars overlap in mass with giant exoplanets circling nearby stars.”

    The smallest rogue planet Langeveld and his colleagues spotted, a gas giant about 5 times the mass of Jupiter (or 1,600 times the mass of Earth, if you prefer), is an important clue. It sits at the heart of a swirling disk of gas and dust, which looks exactly like the disks that form around newborn stars, where material eventually coalesces into planets. That suggests that the planet probably formed like a star, just from a smaller cloud of gas and dust. And it may be forming its own miniature system, like Jupiter or Saturn with their swarms of moons.

    In other words, rogue planets may not always be planets that formed in orbit around a star like our Sun, only to get kicked out of the star system by a close encounter with a sibling planet or a passing star (which may have happened at least once in our own Solar System’s history). Instead, they can apparently spawn all alone, from much smaller clouds of gas than the ones that form stars.

    “This is important context for understanding both star and planet formation,” says Langeveld in a recent statement.

    What’s Next?

    Langeveld and his colleagues hope to learn more about these lonely planets’ atmospheres in their next round of observations with JWST. Once they have that information, they’ll compare the rogue gas giants’ atmospheres to brown dwarfs and to “normal” gas giants that orbit stars. That could offer clues about whether gas giants that coalesce alone in the middle of space contain a different mix of elements than those that form in the disks around newborn stars.

    The astronomers also hope to find more objects like the small rogue planet with its own little protoplanetary disk. That could shed light on whether, or how, rogue planets might form their own systems of planets (or moons). Picture all the diverse worlds that orbit the gas giants in our Solar System — Jupiter’s icy moon Europa and volcanic hellworld Io, or Saturn’s Titan with its methane seas — orbiting a version of Jupiter all alone in deep space, unlit by any star, heated only by the tidal pull of their planet.

    “The diversity of systems that nature has produced is remarkable and pushes us to refine our models of star and planet formation,” says Jayawardhana.

    Microplastics Can Cross the Blood-Brain Barrier, A New Study Suggests — Here’s Why That Matters

    Plastic levels in the brain were much higher than in organs surveyed.

    It feels like every few months, microplastics are cropping up someplace else they don’t belong: testiclesplacentascarotid artery plaque, lungs. These infinitesimally small plastic particles, which are smaller than 5 millimeters across, have most recently been detected in brains, according to a new study.

    A preprint study — which is a scientific study that has not yet been reviewed by other scientists for publication in a journal — was posted online in May by the National Institutes of Health looking at the amount of microplastics in human brain samples from autopsies. The study found that brains had higher concentrations of microplastics than other organs, and that these autopsy samples also had higher concentrations of microplastics than autopsy samples from a 2016 study. Though this paper is still under review to ensure the methods and findings are trustworthy, the key results of the study exemplify yet another vital organ affected by microplastics.

    For the study, the authors examined livers, kidneys, and brains from autopsied cadavers. They found that concentrations of microplastics in the brain samples they examined “ranged from 7 to 30 times the concentrations seen in livers or kidneys.” They also found that brain samples collected and analyzed in 2024 contained significantly higher concentrations of microplastic, with over 3,000 micrograms per gram of human tissue in 2016 and over 4,800 micrograms per gram in 2024. Some samples ranged as high as more than 8,800 micrograms of plastic per gram of brain tissue.

    We don’t know yet what effects, if any, microplastics could have on the brain, but this study does confirm that these bits of plastic can cross the blood-brain barrier, which is the protective membrane that helps regulate what molecules enter the brain from circulating blood.

    “Based on our observations, we think the brain is pulling in the very smallest nanostructures, like 100 to 200 nanometers in length, whereas some of the larger particles that are a micrometer to five micrometers go into the liver and kidneys,” lead author of the study Matthew Campen, a toxicologist and professor of pharmaceutical sciences at the University of New Mexico in Albuquerque, told CNN.

    While it seems like microplastics are omnipresent in today’s society, figuring out how to affect our health is key.

    The team that delivered the first-ever image of a black hole is getting more ambitious.

    The team behind the first ever image of a black hole can now observe the same celestial gargantuan with greater definition than ever before.

    On Tuesday, the Event Horizon Telescope (EHT) team announced that their global network of radio telescopes, which turns Earth into one giant virtual telescope, can observe at a new radio frequency. This means a few things. First, the team can get crisper imagery of the supermassive black hole at the center of galaxy M87, which starred in the first ever image of a black hole, taken in 2017 and published in 2019. Second, having an additional frequency means the team can play with color.

    “This new ‘color vision’ allows us to tease apart the effects of Einstein’s gravity from the hot gas and magnetic fields that feed the black holes and launch powerful jets that stream over galactic distances,” Sheperd “Shep” Doeleman, astrophysicist and Founding Director of the EHT, said in an announcement published Tuesday.

    Two rings, side by side, show the same supermassive black hole. The first ring is thicker, with a du...

    EHT, D. Pesce, A. Chael

    Two is better than one

    Doeleman tells Inverse that supermassive black holes are busy places. Seeing two frequencies would reveal more of its organized chaos. The team has published simulation images to depict how the new frequency changes the view.

    “When you have two separate frequencies, you’re able to tease apart different effects around the black hole,” Doeleman says.

    Albert Einstein predicted that gravity bends all light, across all wavelengths, in the same way. Right around the black hole’s shadow, where gravity is so strong that not even light can reflect back out, data across both frequencies may look the same.

    But farther away from the event horizon, other phenomena like the black hole’s jets of superheated plasma will look differently from one frequency to the next.

    Seeing in color

    Having two sets of information allows for color. The data from the telescopes is radio, a wavelength of light invisible to human eyes. The single color of existing EHT images are packed with information at 230 GHz. But now that EHT can take observations at 345 GHz, imagery specialists can add a new color to the golden ring. This will be exciting to view not only as a still image, but eventually, as a motion picture.

    The Event Horizon Telescope, a collection of telescopes around the world, can now capture data on th...

    EHT, D. Pesce, A. Chael

    Doeleman and other researchers hope the telescopes in the EHT network will be able to take not just two radio wavelengths at the same time, but eventually three.

    “The EHT's successful observation at 345 GHz is a major scientific milestone,” Lisa Kewley, Director of the Center for Astrophysics | Harvard & Smithsonian, said in the announcement. “By pushing the limits of resolution, we’re achieving the unprecedented clarity in the imaging of black holes we promised early on, and setting new and higher standards for the capability of ground-based astrophysical research.”

    A NASA Rocket Has Finally Found Earth’s Global Electric Field

    Scientists have discovered that Earth has a third field. We all know about the Earth’s magnetic field. And we all know about Earth’s gravity field, though we usually just call it gravity.

    Now, a team of international scientists have found Earth’s global electric field.

    It’s called the ambipolar electric field, and it’s a weak electric field that surrounds the planet. It’s responsible for the polar wind, which was first detected decades ago. The polar wind is an outflow of plasma from the polar regions of Earth’s magnetosphere. Scientists hypothesized the ambipolar field’s existence decades ago, and now they finally have proof.

    The discovery is in a new article in Nature titled “Earth’s ambipolar electrostatic field and its role in ion escape to space.” The lead author is Glyn Collinson from the Heliophysics Science Division at NASA Goddard Space Flight Center.

    “It’s like this conveyor belt, lifting the atmosphere up into space.”

    Glyn Collinson, Heliophysics Science Division, NASA Goddard Space Flight Center

    The Space Age gained momentum back in the 1960s as the USA and USSR launched more and more satellites. When spacecraft passed over the Earth’s poles, they detected an outflow of particles from Earth’s atmosphere into space. Scientists named this the polar wind, but for decades, it was mysterious.

    Scientists expect some particles from Earth to “leak” into space. Sunlight can cause this. But if that’s the case, the particles should be heated. The wind is mysterious because many particles in it are cold despite moving at supersonic speeds.

    “Something had to be drawing these particles out of the atmosphere,” said lead author Collinson.

    Collinson is also the Principal Investigator for NASA’s “Endurance” Sounding Rocket Mission. “The purpose of the Endurance mission was to make the first measurement of the magnitude and structure of the electric field generated by Earth’s ionosphere,” NASA writes in their mission description. Endurance launched on May 22nd, 2022, from Norway’s Svalbard Archipelago.

    This image shows NASA's Endurance rocket launching from Ny-Ålesund, Svalbard, Norway. It flew for 19 minutes to an altitude of about 780 km (484 mi) above Earth's sunlit polar cap. It carried six science instruments and could only be launched in certain conditions to be successful. Image Credit: NASA/Brian Bonsteel.

    “Svalbard is the only rocket range in the world where you can fly through the polar wind and make the measurements we needed,” said Suzie Imber, a space physicist at the University of Leicester, UK, and co-author of the paper.

    Svalbard is key because there are open magnetic field lines above Earth’s polar caps. These field lines provide a pathway for ions to outflow to the magnetosphere.

    After it was launched, Collinson said, “We got fabulous data all through the flight, though it will be a while before we can really dig into it to see if we achieved our science objective or not.”

    Now, the data is in, and the results show that Earth has a global electric field.

    Prior to its discovery, scientists hypothesized that the field was weak and that its effects could only be felt over hundreds of kilometres. Even though it was first proposed 60 years ago, scientists had to wait for technology to advance before they could measure it. In 2016, Collinson and his colleagues began inventing a new instrument that could measure the elusive field.

    At about 250 km (150 mi) above the Earth’s surface, atoms break apart into negatively charged electrons and positively charged ions. Electrons are far lighter than ions, and the tiniest energetic jolt can send them into space. Ions are more than 1800 times heavier, and gravity draws them back to the surface.

    If gravity were the only force at work, the two populations would separate over time and simply drift apart. But that’s not what happens.

    Electrons and ions have opposite electrical charges. They’re attracted to one another and an electric field forms that keeps them together. This counteracts some of gravity’s power.

    The field is called ambipolar because it’s bidirectional. That means it works in both directions. As ions sink down due to gravity, the electrical charges mean that the ions drag some of the electrons down with them. However, at the same time, electrons lift ions high into the atmosphere with them as they attempt to leave the atmosphere and escape into space.

    via GIPHY

    The result of all this is that the ambipolar field extends the atmosphere’s height, meaning some of the ions escape with the polar wind.

    After decades of hypothesizing and theorizing, the Endurance rocket measured a change in electric potential of only 0.55 volts. That’s extremely weak but enough to be measurable.

    “A half a volt is almost nothing — it’s only about as strong as a watch battery,” Collinson said. “But that’s just the right amount to explain the polar wind.”

    Hydrogen ions are the most plentiful particles in the polar wind. Endurance’s results show that these ions experience an outward force from the magnetic field that’s 10.6 times more powerful than gravity. “That’s more than enough to counter gravity — in fact, it’s enough to launch them upwards into space at supersonic speeds,” said Alex Glocer, Endurance project scientist at NASA Goddard and co-author of the paper.

    Hydrogen ions are light, but even the heavier particles in the polar wind are lifted. Oxygen ions in the weak electrical field effectively weigh half as much, yet they’re boosted to greater heights, too. Overall, the ambipolar field makes the ionosphere denser at higher altitudes than it would be without the field’s lofting effect. “It’s like this conveyor belt, lifting the atmosphere up into space,” Collinson added.

    “The measurements support the hypothesis that the ambipolar electric field is the primary driver of ionospheric H+ outflow and of the supersonic polar wind of light ions escaping from the polar caps,” the authors explain in their paper.

    “We infer that this increases the supply of cold O+ ions to the magnetosphere by more than 3,800%,” the authors write. At that point, other mechanisms come into play. Wave-particle interactions can heat the ions, accelerating them to escape velocity.

    These results raise other questions. How does this field affect Earth? Has the field affected the planet’s habitability? Do other planets have these fields?

    Back in 2016, the European Space Agency’s Venus Express mission detected a 10-volt electric potential surrounding the planet. This means that positively charged particles would be pulled away from the planet’s surface. This could draw away oxygen.

    Scientists think that Venus may have once had plentiful water. However, since sunlight splits water into hydrogen and oxygen, the electric field could’ve siphoned the oxygen away, eliminating the planet’s water. This is theoretical, but it begs the question of why the same thing hasn’t happened on Earth.

    The ambipolar field is fundamental to Earth. Its role in the evolution of the planet’s atmosphere and biosphere is yet to be understood, but it must play a role.

    “Any planet with an atmosphere should have an ambipolar field,” Collinson said. “Now that we’ve finally measured it, we can begin learning how it’s shaped our planet as well as others over time.”

    • Satellite images show a giant hole in Siberia is rapidly expanding.
    • The Batagay megaslump is a result of the ground thawing and collapsing as Arctic temperatures rise.
    • It's an extreme case of a changing Arctic landscape accelerating the climate crisis.

    giant hole in the earth is breaking open the land in Siberia, and photos from space show it's growing rapidly.

    It resembles a stingray, a horseshoe crab, or a giant tadpole. It started as a sliver, barely visible in declassified satellite imagery from the 1960s.

    Now it's a chasm with steep cliffs, clearly visible from space.

    The hole tripled in size between 1991 and 2018, according to the US Geological Survey.

    The Batagay crater, sometimes referred to as Batagaika or the "gateway to hell," represents a much larger, often invisible problem that affects the entire planet.

    What is this hole in Siberia?

    The Arctic is heating up faster than the rest of Earth, and that's quickly thawing the permafrost, which is a thick layer of soil that's permanently frozen — at least, it used to be.

    The Batagay crater isn't actually a crater at all. It's the world's largest "retrogressive thaw slump," a pit that forms when permafrost thaw causes the ground to cave in, creating a landslide as the earth at its edges slumps into the pit.

    There are thousands of thaw slumps across the Arctic. But the size of the Batagay "crater" has earned it the title of megaslump. It's named for the nearby town of Batagay.

    "Permafrost is not the most, let's say, photogenic of subjects," Roger Michaelides, a geophysicist at Washington University in St. Louis, told Business Insider. "You're talking mostly about frozen dirt underground, which by definition you often can't see unless it's been exposed somehow, like in this megaslump."

    That makes the Batagay pit a bit of a permafrost celebrity and an omen of what lies ahead.

    The Batagay megaslump could help decode our planet's future

    As permafrost thaws, all the dead plants and animals that have been frozen inside it for centuries start to decompose, belching carbon dioxide and methane into the atmosphere.

    Those are powerful heat-trapping gases, which cause global temperatures to rise even more, triggering even faster permafrost thaw.

    This vicious cycle could have dire effects. Permafrost covers 15% of the land in the Northern Hemisphere and contains twice as much carbon as the atmosphere.

    One study estimated that permafrost thaw could emit as much planet-warming gases as a large industrial nation by 2100 if industries and countries don't aggressively rein in their own emissions today.

    "There's a lot we don't know about this feedback loop and how it will play out necessarily, but the potential is there for very large changes to the climate system occurring over very, very fast geologic timescales," Michaelides said.

    In short, permafrost thaw could quickly make the climate crisis much worse. But it's still a mysterious process. Studying extreme sites like the Batagay megaslump can help scientists understand permafrost thaw and see into the future.

    In a study published in the journal Geomorphology in June, researchers used satellite and drone data to construct 3D models of the megaslump and calculate its expansion over time.

    They found that about 14 Pyramids of Giza's worth of ice and permafrost had thawed at Batagay. The crater's volume increases by about 1 million cubic meters every year.

    "These values are truly impressive," Alexander Kizyakov, the study's lead author and a scientist at Lomonosov Moscow State University, told BI in an email.

    "Our results demonstrate how quickly permafrost degradation occurs," he added.

    The researchers also calculated that the megaslump releases about 4,000 to 5,000 tons of carbon each year. That's about as much as the annual emissions from 1,700 to 2,100 US homes' energy use.

    Michaelides said those numbers didn't surprise him, but they can help inform models of future permafrost thaw and emissions.

    "I think there is a lot we can learn from Batagaika, not only in terms of understanding how Batagaika will evolve with time, but also how similar features might develop and evolve over the Arctic," Michaelides said. "Even if they're a tenth or a hundredth the size of Batagaika, the physics is fundamentally the same."

    Are UFOs in the Bible? Exploring the Link Between Angels and Extraterrestrials

    The intersection of religious belief and extraterrestrial life has long intrigued both theologians and enthusiasts of the unexplained. This curiosity often leads to the question: could the Bible contain references to what we now describe as UFOs or extraterrestrial beings? A recent discussion, featuring U.S. Congressman Tim Burchett and theologian Dr. Paul Thigpen, delved into this very topic, exploring the possibility that some biblical accounts could be interpreted as encounters with non-human intelligence, perhaps even extraterrestrial.

    Biblical References to Anomalous Phenomena

    Several passages in the Bible describe events that, to a modern reader, might seem reminiscent of UFO sightings. For example, the book of Ezekiel recounts a vision in which the prophet sees a “whirlwind coming out of the north, a great cloud with a raging fire engulfing itself” (Ezekiel 1:4). Within this cloud were creatures with an extraordinary appearance, leading some to speculate whether this could be an ancient description of a UFO encounter.

    Similarly, the account of Elijah being taken up into heaven in a “whirlwind” with “chariots of fire” (2 Kings 2:11) has also been cited as a possible reference to extraterrestrial technology. The imagery used in these passages—wheels within wheels, flying chariots, and bright lights—bears a striking resemblance to descriptions of unidentified flying objects in modern times.

    Theological Interpretations

    Congressman Burchett, a devout Christian, expressed that he has no difficulty reconciling his faith with the possibility of extraterrestrial life. He argues that the vastness of God’s creation could easily encompass other life forms beyond Earth, and that such beings might have been referenced in the Bible using the language and understanding of the time. For Burchett, the idea that Ezekiel’s vision could describe a UFO does not weaken his faith; rather, it broadens his perspective on the universe’s complexity.

    Dr. Paul Thigpen, on the other hand, approaches the subject with caution. He acknowledges that the Bible does describe non-human intelligences, such as angels and demons, but he is hesitant to equate these beings with extraterrestrials as understood in contemporary UFO lore. Thigpen emphasizes that biblical references to angels and other supernatural entities should be interpreted within the context of their religious significance, not necessarily as evidence of alien encounters.

    The Debate Over Angels and Aliens

    The conversation between Burchett and Thigpen highlights a broader debate within both religious and UFO communities: are angels and other biblical beings simply manifestations of divine power, or could they be visitors from other worlds? The traditional Christian view holds that angels are purely spiritual beings created by God, distinct from any physical extraterrestrial life forms. These beings do not have bodies and do not exist within our space-time in the way that humans or hypothetical aliens might.

    However, the overlap between descriptions of angels and modern UFO encounters has led some to speculate that biblical accounts could be ancient interpretations of alien visitations. This theory posits that the “angels” seen by biblical figures might have been beings from another planet, whose advanced technology and abilities were interpreted as divine or supernatural.

    UFOs and the Vatican

    The discussion also touched on the Catholic Church’s stance on extraterrestrial life. Historically, the Vatican has shown a keen interest in astronomy, and some Popes have even entertained the possibility of life beyond Earth. Pope John Paul II, when asked about aliens, responded that “they are God’s children too,” suggesting an openness to the idea that other intelligent beings could exist within God’s creation.

    Additionally, there have been claims, such as those mentioned by David Grusch, a former U.S. intelligence officer, that the Vatican might have been involved in secret activities related to UFOs, including the transfer of alleged extraterrestrial technology during World War II. While these claims remain unproven, they add another layer of intrigue to the conversation about religion and extraterrestrial life.

    Conclusion: A Broader Perspective on Faith and the Universe

    The idea that the Bible might contain references to UFOs or extraterrestrials is a fascinating one that challenges traditional interpretations of religious texts. For some, like Congressman Burchett, this possibility enhances the awe of God’s creation, suggesting that humanity is not alone in the universe. For others, like Dr. Thigpen, it is important to maintain a distinction between spiritual beings as described in the Bible and the physical entities that might exist elsewhere in the cosmos.

    Ultimately, the discussion about angels, aliens, and UFOs in the Bible invites believers and skeptics alike to explore the mysteries of faith and the universe with an open mind. Whether these biblical passages are read as metaphorical, spiritual, or literal accounts, they continue to inspire curiosity and wonder about our place in the vastness of creation.

    Giant Low-Frequency Scan Searches for Aliens in 2,800 Galaxies

    The search for extraterrestrial intelligence (SETI) has fascinated us for decades. Now a team of researchers have used the Murchison Widefield Array in Australia to scan great swathes of sky for alien signals. Unusually for a SETI project, this one focussed attention on 2,800 galaxies instead of stars within our own. They have been on the lookout for advanced civilisations that are broadcasting their existence using the power of an entire star. Alas they weren’t successful but its an exciting new way to search for alien intelligence. 

    Our first attempts to search for alien intelligence began back in 1960 with Project Ozma. It was led by astronomer Frank Drake and used the 85 foot radio telescope at Green Bank in West Virginia. The aim was to try and detect alien radio signals from Epsilon Eridani and Tau Ceti, should they have existed. Alas they found nothing but it marked the first step in a scientific approach to search for extraterrestrial intelligence. Typically SETI tends to focus on electromagnetic signals such as radio waves an in particular unusual patterns that could suggest intentional communication.

    This recent attempt to try out a new approach was led by Dr Chenoa Tremblay of the SETI Institute and Prof. Steven Tingay from the Curtin University. The approach was to utilise the magnificent field of view of the Murchison Widefield Array (MWA) which allows one observation to cover 2,800 galaxies. Among them, there are 1,300 galaxies that we know the distance too. The MWA in Western Australia utilises low frequencies (100MHz) to probe the distant galaxies. 

    By searching these galaxies for signs of alien signals we are actually looking for advanced civilisations. It’s one thing to be able to send radio signals across interstellar space, indeed we have been doing that for decades since the advent of radio communication. As radio signals propagate across space, they weaken and certainly could not traverse the immense distances between the galaxies. It’s just possible that advanced civilisations might have the technology to harness the power of their Sun and perhaps other stars in their galaxy to send signals powerful enough to travel the millions of light years between galaxies. 

    I quite love the idea of advanced civilisations that may have developed the technology to transmit ‘technosignatures’ or signs of alien technology across the Universe but alas the study did not find any. Queue sad emoji 🙁  It did however provide valuable insight into just how we may be able to widen our search for alien intelligence beyond the Milky Way. 

    The MWA uses thousands of dipole antennae that are spread across several kilometres giving it a wide 30 degree field of view. It has been designed to operate between 70 and 300 MHz allowing it to participate in studies of the early universe, mapping the cosmos, and detecting solar activity. It helped advance radio and interferometry technology facilitating the development of the Square Kilometre Array.

    Using MWA and other radio installations to study the properties of stars and galaxies also allows for the search for technosignatures. It’s a new approach and it highlights the importance of continuing the development of new technology to open up new ways to search for ET.

    ESA Cluster Satellite to Reenter in Early September

    • The first of a set of groundbreaking Cluster satellites is set for a controlled reentry next week.

    The European Space Agency is paving the way in controlled reentry technology. ESA recently announced that plans to terminate the first of four Cluster satellites is about to come to fruition in early September, with the reentry of Salsa.

    The Reentry

    Salsa is one of four dance-themed Cluster satellites. The other three are Rumba, Samba and Tango. ESA controllers used the remaining thruster fuel on the spacecraft back in January to lower the perigee of the mission down to around 100 kilometers, which will assure destructive reentry for the 550 kilogram satellite over the South Pacific on or around September 8th. The area the satellite will meet its demise is known as ‘Point Nemo’ or the Pacific Ocean Uninhabited Area. The region has seen several large reentries over the years, including the Mir space station and ESA’s Automated Transfer Vehicle. The region will likely see the demise of the International Space Station sometime around 2030.

    “By studying how Salsa burns up, which parts might survive, for how long and in what state, we will learn much about how to build ‘zero debris’ satellites,” says Tim Flohrer, (ESA-Space Debri Office) in a recent press release.

    A Pioneering Mission

    ESA designed the Cluster mission to explore space weather interactions with the Earth’s magnetic environment as the four spacecraft fly in a tetrahedral configuration through the planet’s magnetosphere. The four spacecraft fly out to a distant apogee of about 117,000 kilometers (over three times farther out versus geosynchronous orbit), and orbit the Earth once every 54 hours.

    Launched in the summer of 2000, the Cluster satellites had a 5-year nominal mission, which lasted well over two decades. The missions have since proven to be pioneers in space weather research. The mission also escaped glitches and software failures over the years, including a bug requiring a “dirty hack” in 2010. Cluster II was also a replacement for the original set of Cluster satellites, which were lost on the inaugural launch of the Ariane-5 rocket on June 4th, 1996 from the Kourou Space Center. The mission ended in an explosion 37 seconds after liftoff.

    Controlling Reentries

    This sort of ‘targeted reentry’ for a long duration mission is one of the first of its kind for ESA. The zero-debris conclusion to the mission exceeds international standards. Furthermore, it also addresses issues surrounding the mitigation of debris in low Earth orbit. On Earth, ESA’s worldwide Estrack network will follow Salsa during its final orbits, and an airborne campaign is underway to spot the final reentry. ESA made a similar effort to image the Aeolus satellite in 2023, shortly before reentry.

    Engineers will apply a similar technique to the SMILE (Solar wind Magnetosphere Ionosphere Link Explorer) and Proba-3 missions. These are also set to enter a similar far-ranging orbit around the Earth. SMILE is the follow-on mission to Cluster, and is launching in late 2025. ESA will launch the Proba-3 solar observatory next month. The mission will feature a free-flying, solar eclipsing disk.

    You can spot the cluster satellites including Salsa on their final days. Salsa is COSPAR ID 2000-041A/26411in the NORAD satellite catalog, and listed in Heavens-Above. The satellites reach naked eye visibility on a good perigee pass.

    After the demise of Salsa, Rumba will also reenter in November of next year, followed by Tango and Samba in August 2026.

    While this is the ‘Last Dance’ for Salsa, the efforts to study space weather and come to terms with space debris continue.

    Hoe een AI-apocalyps te voorkomen

    Artikel door Dominique Dewitte
     Hoe een AI-apocalyps te voorkomen

    Iets meer dan een jaar geleden bracht het in San Francisco gevestigde OpenAI zijn chatbot ChatGPT op de markt, wat een goudkoorts veroorzaakte voor kunstmatige intelligentie en het eeuwenoude debat over de effecten van automatisering op het welzijn van mensen weer op gang bracht.

    De angst voor verdringing door machines gaat terug tot de Industriële Revolutie in de 19e eeuw, toen groepen Engelse handwevers, bekend als Luddites, begonnen met het vernietigen van de elektrische weefgetouwen die hun levensonderhoud bedreigden. De beweging, die een hoogtepunt bereikte tussen 1811 en 1817, werd uiteindelijk onderdrukt door de regeringstroepen en de leiders werden geëxecuteerd of verbannen naar Australië.

    Luddieten zaten ernaast

    Maar de argumenten van de Luddieten vonden een onverwachte (en enigszins ironische) voorvechter in de beroemde econoom David Ricardo, die in zijn boek On the Principles of Political Economy and Taxation uit 1817 betoogde dat “de mening van de arbeidersklasse dat het gebruik van machines vaak schadelijk is voor hun belangen, niet gebaseerd is op vooroordelen en fouten, maar in overeenstemming is met de juiste principes van de politieke economie”. De Britse econoom Nassau Senior adviseerde de wevers om “uit die productietak te stappen”.

    Uiteindelijk deden ze precies dat: 250.000 banen op handweefgetouwen verdwenen tussen 1820 en 1860. Maar terwijl de mechanisatie uiteindelijk de menselijke arbeiders ten goede kwam – de bevolking en het reële inkomen per hoofd van de bevolking in het Verenigd Koninkrijk verveelvoudigden in dezelfde periode – had het een nadelige invloed op de paarden, wier aantallen sterk daalden toen treinen (en later gemotoriseerde voertuigen) het door paarden getrokken vervoer vervingen.

    Meer waardevolle bezigheden

    Sinds de Industriële Revolutie is het overheersende pro-machine argument dat door het verhogen van de arbeidsproductiviteit, automatisering het reële inkomen verhoogt, waardoor meer mensen van een hogere levensstandaard kunnen genieten zonder dat er banen verloren gaan. Bovendien heeft de bevrijding van vervelende ondergeschikte taken ons in staat gesteld onze energie te richten op meer waardevolle bezigheden.

    De hedendaagse tegenhangers van de Luddieten benadrukken daarentegen de nadelen van automatisering, vooral het potentieel om bestaansmiddelen en gemeenschappen te vernietigen. Een rechtvaardige verdeling van inkomen en macht is volgens hen cruciaal om op lange termijn de vruchten te kunnen plukken van technologische vooruitgang. Technopessimisten zoals Martin Ford en Daniel Susskind hebben beweerd dat opkomende technologieën zoals AI te weinig nieuwe banen zullen creëren, wat zal leiden tot meer armoede en “technologische werkloosheid”.

    Menselijk werk uitbreiden in plaats van vervangen

    De opkomst van generatieve AI en de verwachte komst van kunstmatige algemene intelligentie – een AI die in staat is om elke cognitieve taak uit te voeren die mensen kunnen uitvoeren – hebben het debat tussen techno-optimisten en techno-sceptici op scherp gezet. In de gezondheidszorg bijvoorbeeld, een schijnbaar eindeloze bron van tech-hypes, belooft AI betere diagnoses, geavanceerde telegeneeskunde, effectievere medicijnen en minder administratieve rompslomp voor artsen en verpleegkundigen, waardoor er meer tijd overblijft voor patiëntenzorg.

    Dit lijkt de heersende opvatting onder mainstream experts te weerspiegelen dat generatieve AI menselijk werk zal uitbreiden in plaats van vervangen. Door routinetaken te automatiseren, belooft het mensen vrij te maken voor creatiever werk. Om zeker te zijn, zal deze transformatie levenslang leren vereisen, waardoor voortdurende educatie een voorwaarde wordt, niet alleen om deel te nemen aan de arbeidsmarkt, maar ook om toegang te krijgen tot een groeiend aanbod van online diensten.

    Een superintelligentie die op hol slaat

    Met de komst van generatieve AI is de bezorgdheid verschoven van door automatisering veroorzaakt banenverlies naar het vooruitzicht van een superintelligentie die op hol slaat – een angst die teruggaat tot Mary Shelley’s roman Frankenstein uit 1818; of, De moderne Prometheus. In navolging van deze gevoelens merkte voormalig Google CEO Eric Schmidt onlangs op dat, hoewel de huidige AI-modellen “onder menselijke controle” blijven, er een reëel risico bestaat dat een AI het vermogen ontwikkelt tot “recursieve zelfverbetering”, autonomie verwerft en “zijn eigen doelen begint te stellen”. Uiteindelijk, waarschuwde hij, zou een “computercluster” zich kunnen ontwikkelen tot een “echt bovenmenselijke expert” die in staat is om zelfstandig te handelen.

    Nu experts en wetenschappers zich steeds meer zorgen maken over het vermogen van AI om de wereld te vernietigen, gaan er steeds meer stemmen op om de ontwikkeling van AI af te stemmen op menselijke doelen en waarden. Er zijn twee manieren om dit te bereiken. De eerste is om de beschikbaarheid en verkoop van potentieel schadelijke AI-gebaseerde producten te beperken, zoals beleidsmakers in Europa en elders hebben geprobeerd door strenge regels op te leggen aan opkomende technologieën zoals autonome auto’s en gezichtsherkenning.

    Regulering komt vaak te laat

    Een duidelijk probleem met deze aanpak is dat het moeilijk is om een consensus te bereiken over wat schade is in een wereld waarin moreel relativisme de norm is. Omdat het steeds onduidelijker wordt wie de “eigenaar” is van inhoud die als schadelijk wordt beschouwd, is het vrijwel onmogelijk om verkopers of providers aansprakelijk te stellen. Bovendien komen pogingen om het gebruik van technologie te reguleren vaak te laat.

    De tweede manier om AI te beteugelen is om de ontwikkeling van potentieel gevaarlijke producten volledig te beperken. Maar het inperken van de vraag is ingewikkelder dan het beperken van het aanbod, vooral in moderne samenlevingen waar concurrerende krachten – zowel commercieel als geopolitiek – het vertragen van technologische innovatie buitengewoon moeilijk maken.

    Onrust bij OpenAI

    De recente onrust bij OpenAI is hier een goed voorbeeld van. In november ontsloeg de raad van bestuur van het bedrijf CEO Sam Altman kortstondig, naar verluidt uit bezorgdheid dat AI op een dag zou kunnen leiden tot het uitsterven van de mensheid. Hoewel Altman slechts enkele dagen later weer werd aangesteld, onderstreepte het schandaal de snelheid waarmee ogenschijnlijk nuttige technologieën existentiële risico’s kunnen worden. Nu snelle commercialisering het blijkbaar wint van voorzichtigheid en concurrentie de ontwikkeling van steeds krachtigere hulpmiddelen versnelt, lijkt een door AI veroorzaakte apocalyps steeds aannemelijker.

    Neo-Luddisme

    De onontkoombare conclusie is dat het reguleren van AI alleen niet genoeg is. Maar door concepten als neo-Luddisme en herverdeling in het publieke debat te introduceren, kunnen we de politieke en intellectuele woordenschat ontwikkelen die nodig is om de bedreigingen van deze opkomende technologieën te beperken.

    Een neo-Luddiet zou zich bijvoorbeeld kunnen afvragen: Waarom zijn welvarende samenlevingen, die al meer dan genoeg produceren voor hun burgers om comfortabel te leven, nog steeds gefocust op het maximaliseren van de groei van het bbp? Eén antwoord zou kunnen zijn dat er geen eerlijke verdeling van rijkdom en inkomen is die ervoor zorgt dat de voordelen van productiviteits- en efficiëntiewinsten breed worden gedeeld.

    Een andere verklaring is dat technologie zelf niet intrinsiek goed of slecht is; het is een middel om een doel te bereiken. En in de huidige politieke economie is “technologische innovatie” vaak een eufemisme om de rijken en machtigen in staat te stellen kapitaal om te leiden van de industrie naar de financiële sector, waardoor ze de voordelen van automatisering monopoliseren en alle anderen immiseriseren.

    China transformeerde maangrond in water: de eerste stap naar echte kolonisatie?

    Dat China plannen heeft om de maan en haar grondstoffen te gebruiken is zeker geen mysterie. Tegelijkertijd heeft het Aziatische land de afgelopen jaren verschillende sondes naar onze satelliet gestuurd, waaronder naar de verborgen kant. Meer recent is echter het nieuws dat een team van Chinese wetenschappers enkele monsters die door de Chang'e 5-missie naar de aarde zijn teruggebracht, heeft gebruikt om water te produceren. Zou dit de eerste stap kunnen zijn naar een toekomstige menselijke aanwezigheid op de maan? Laten we het samen uitzoeken!

    Chang'e 5 en de maanmonsters teruggebracht naar de aarde

    Zoals de naam al doet vermoeden, is de Chang'e 5-missie zeker niet de eerste die op de maan is gearriveerd. Het bijzondere aan deze missie is dat er voor het eerst in 44 jaar monsters van de maanbodem naar de aarde zijn teruggebracht. Ondanks de daaropvolgende Chang'e 6-missie, waarbij in plaats daarvan de verborgen kant van onze satelliet werd betrokken, zijn de resultaten van Chang'e 5 simpelweg buitengewoon. Zoals te lezen is in een recente studie gepubliceerd in het tijdschrift The Innovation, hebben Chinese wetenschappers ontdekt dat de mineralen waaruit de bodem van de maan bestaat rijk zijn aan waterstof en kunnen worden gebruikt om ter plekke water te produceren. Maar hoe?

    De methode waarmee je water uit eenvoudige grond kunt halen, vereist het verwarmen van de mineralen waaruit het bestaat tot extreem hoge temperaturen, om een ​​chemische reactie van de elementen met waterstof te veroorzaken en daardoor tot de vorming van waterdamp te leiden.

    Hoe je water van de Maan krijgt

    Weergave van de manieren waarop het mogelijk zou zijn om water te produceren vanuit de maangrond

    Chen et al./The Innovation - 2024

    Dankzij de innovatieve methode van Chinese wetenschappers kan uit elke ton maangrond ongeveer 50 liter water worden gewonnen. Het lijkt misschien niet veel, en het is ongetwijfeld een proces dat om verschillende redenen op aarde geen zin zou hebben. Op de maan verandert dit echter: 50 liter water kan voorzien in de dagelijkse behoeften van de leden van een hypothetische menselijke missie op een hypothetische maanbasis. De maanbasis vormt een concreet doel van de Chinese ruimteverkenning: het ter plekke kunnen produceren van water zou een enorm voordeel betekenen.

    In feite wil China vòòr 2035 een permanent onderzoeksstation op de maan bouwen, terwijl China vòòr 2045 een ruimtestation in een baan rond de satelliet wil bouwen. Als Chang'e 5 na 44 jaar de eerste missie was die maanmonsters terugbracht, is de Chang'e 6-missie de eerste die monsters van de andere kant van de maan terugbracht. Kortom: China lijkt het serieus te nemen.

    Naar een toekomstige maanbasis... en verder

    Dat het mogelijk is om water rechtstreeks uit de maanbodem te halen is buitengewoon nieuws dat echter ook een aantal overwegingen met zich meebrengt. Allereerst moeten we begrijpen hoeveel energie er nodig is om de bodem te verwarmen en welke andere elementen betrokken zijn bij het proces van waterdampvorming. Ten tweede mogen we de geopolitieke implicaties niet vergeten van de belangstelling die China toont voor onze satelliet: de concurrentie om maanbronnen zal in de toekomst steeds levendiger worden. En mogelijk ook heviger.

    Kortom, de resultaten van de Chinese Academie van Wetenschappen laten zien hoe het mogelijk is om steeds dichter bij het idee van een permanente aanwezigheid van de mens op de maan te komen. Aan de andere kant zijn er tientallen jaren verstreken sinds de laatste keer dat een astronaut een wandeling maakte op onze satelliet. De volgende zou wel eens een ruimtestation op de maan kunnen bewonen, op haar grond kunnen lopen... en haar water kunnen drinken.

    Het “echte” Atlantis bestaat en bevindt zich in Griekenland: een stad die al 2400 jaar onder water staat

    Bijna alle culturen zijn gefascineerd door verhalen over grote overstromingen of compleet verzonken beschavingen. Een van de bekendste mythen is ongetwijfeld die over Atlantis, de legendarische stad die volgens Plato in de golven verdween en waarvan het bestaan nog steeds wordt onderzocht. Misschien is Atlantis alleen maar een fantasie, maar het is mogelijk dat juist een oude stad verhalen over verzonken beschavingen heeft geïnspireerd. Het verschil is dat het een plaats is die echt heeft bestaan en waarvan de overblijfselen ook zijn gevonden.

    Het verhaal van Helike, een stad verzonken in de golven

    We bevinden ons in de Peloponnesos aan het begin van de vierde eeuw voor Christus: Helike is een bloeiende stad en zetel van de Achaeïsche Liga, een alliantie van verschillende Griekse poleis. In 373 v.Chr. werd echter binnen een paar uur een hele stad onder water gezet door de golven als gevolg van een sterke aardbeving, en verdween met haar tempels, huizen en inwoners. Het lijkt een verhaal dat we al eerder hebben gehoord, en dat miljoenen mensen vanaf dat moment zullen horen, zij het onder een andere naam.

    De verdwijning van Helike moet in de eerste plaats gevolgen hebben gehad voor de burgers van de Griekse poleis, waaronder verschillende schrijvers die de gebeurtenissen beschreven of zich herinnerden. Later wekten de literaire getuigenissen echter een ander soort nieuwsgierigheid: eeuwen na het verhaal van Helike vroegen veel geleerden zich af waar deze stad verdwenen zou kunnen zijn en vooral of het mogelijk is om haar terug te vinden.

    Archeologische opgravingen: de herontdekking van Helike

    De opgravingen die de overblijfselen van Helike aan de oppervlakte hebben brachten

    Om te begrijpen waar de overblijfselen van de stad Helike konden rusten, analyseerden onderzoekers de geologische veranderingen die de noordelijke Peloponnesos troffen. En na eeuwen van vergetelheid leverden de onderzoeken eindelijk enkele resultaten op: aan het begin van de 21e eeuw werden overblijfselen gevonden die verenigbaar waren met de klassieke stad, niet ver van de positie die in de bronnen wordt vermeld. Daarnaast hebben archeologen in het gebied ook een nederzetting gevonden die dateert uit de late bronstijd.

    De Helike Foundation en het Helike Project houden zich al jaren bezig met de ontdekkingen, met doelstellingen variërend van onderzoek naar de oude Griekse stad en de verschijnselen die de verdwijning ervan veroorzaakten, tot de verspreiding en bescherming van de opgravingslocaties. Om deze reden is Helike opgenomen in de lijst van sites die het meeste risico lopen van het World Monuments Fund.

    Is Helike Atlantis?

    Ja en nee. Naast de voor de hand liggende overeenkomsten die ook door het verhaal van hun verdwijning worden gegeven, zouden Helike en Atlantis meer met elkaar verbonden kunnen zijn dan we denken, althans op narratief niveau. Naast de wetenschappelijke pogingen om het oude Helike te identificeren, mogen we de datum van de gebeurtenis niet vergeten: deze vond plaats in dezelfde periode waarin Plato zijn dialogen schreef, inclusief die waarin hij spreekt over de mythe van Atlantis.

    Natuurlijk kunnen mythen uit het verleden, zoals de Minoïsche uitbarsting die leidde tot de ondergang van het eiland Santorini, hebben bijgedragen aan het verhaal van de filosoof. Maar Plato kan ook geïnspireerd zijn geraakt door het fenomeen dat de verdwijning van Helike veroorzaakte. Per slot van rekening is dat van Atlantis ook om deze reden een mythe: het lijkt op veel echte gebeurtenissen, maar kan niet tot één daarvan worden herleid.

    UFO myth-buster reveals the crazy encounter even he cannot explain

    A top UFO debunker has revealed the bizarre case that still puzzles him to this day. 

    Scores of people, including military experts, have recorded eerie videos appearing to show UAPs - unidentified aerial phenomena - over the years and often seek answers by posting them online.

    Mick West, of Sacramento, California, uses a range of tools to help explain these mysteries - but has been stumped by one Navy video of a UFO that was leaked by The New York Times

    The footage released in 2017 had been taken by a Navy F/A-18 Super Hornet pilot two years earlier and appears to show a UFO following the jet from the USS Theodore Roosevelt after the object had been detected by radar off the East Coast. 

    In the infrared cockpit video, the incredible high-speed object seemingly breaks the laws of physics - with the two pilots heard debating whether or not it was a drone. 

    Mick West, of Sacramento, California, uses several tools to debunk random flying objects, including FlightAware, Flight Radar 24, and Invisor. But his biggest help is Sitrec that integrates flight data, video, and satellite imagery

    Mick West, of Sacramento, California, uses several tools to debunk random flying objects, including FlightAware, Flight Radar 24, and Invisor. But his biggest help is Sitrec that integrates flight data, video, and satellite imagery 

    One case that piqued West's interest is footage taken by Navy F/A-18 Super Hornet pilot Ryan Graves.  West wants to review the original video files himself to better understand their data

    One case that piqued West's interest is footage taken by Navy F/A-18 Super Hornet pilot Ryan Graves.  West wants to review the original video files himself to better understand their data

    Combing over the footage, West, who often relies on data surrounding the video to debunk recorded events, investigated the clip and tried to work out the rotation of the camera and the glare on the lens. Still, he was left with no answers. 

    West is now hoping to gain access to the original radar data instead of the analysis the government released so he can recreate the phenomenon - and rule out any reasonable explanations.

    As part of his approach, West uses multiple tools including FlightAware, Flight Radar 24 and Invisor, an app that gives information on video, audio, and photos such as resolutions and the date they were taken. 

    But his biggest resource is Sitrec - a tool he designed himself that stands for 'situation recreation' - which integrates flight data, video and satellite imagery to paint a full picture, he told Popular Mechanics

    'You have to be very careful about what you're looking at...for me, that's the very first step in investigating a case,' West, who has investigated around 1,000 UFO cases, told the outlet. 

    Last month, the former video game programmer spotted a white, elongated object from a plane window while he was flying to Pasadena and took a quick video of it. 

    'It’s not an intuitive thing, and if you don’t delve too deeply into it, [you’ll be wrong],' said West, who programmed Tony Hawk's Pro Series games

    'It’s not an intuitive thing, and if you don’t delve too deeply into it, [you’ll be wrong],' said West, who programmed Tony Hawk's Pro Series games

    'It can be very difficult to figure out…but you have no choice,' he added (Pictured: Sitrec)

    'It can be very difficult to figure out…but you have no choice,' he added (Pictured: Sitrec) 

    He thought was just another airplane - a conclusion he would be right about - but he found himself needing to investigate the matter personally, he told Popular Mechanics. 

    When he got to his hotel room, he used Photoshop to closely look at the image and downloaded the GPS routes from his flight and a few others in the area from FlightAware.com. 

    In order for West to find an answer, he has to look at simultaneous events and see how they all fit into the bigger picture.

    His plane wasn't the only in the air, so he had to look at other flight paths, as well as  weather phenomenon and satellite data. 

    He also looks closely at the video angle, In his case, he knew the video he took was several thousand feet above ground and the object was below him.  

    He used Flight Aware 24 to configure where other nearby planes were so he could 'figure out what’s actually in the air at a particular time,' he told Popular Mechanics. 

    West then zoomed in on his own flight and found the exact location of his plane when he took the video. 

    'I knew I was sitting on the right side of the plane,' he told the outlet. 

    The map showed him a 'likely contender' - a plane that had taken off from LA's Van Nuys Airport. 

    'That matches what we see in the video,' he told Popular Mechanics. 

    He then used Sitrec - which an unidentified organization paid him to develop and make publicly accessible - to point the camera from his plane directly down onto where the other plane was traveling. 

    'I set the camera to point from my plane to the other two. One of them matched exactly. It was a small Cessna,' he told the outlet. 'This confirms that this was the plane I was actually looking at.'

    One Unidentified Anomalous Phenomena (UPA) - the term that took over for UFO in 2023 - that piqued West's interest appeared in footage the Chilean Navy caught of a black blob leaving streaks behind it in 2014, he told Popular Mechanics. 

    The Chilean military investigated the footage for roughly two years and boldly determined it to be aliens. 

    He determined the black blob seen by Chilean authorities was just a plane that had just departed from Santiago Airport, and the reason it appeared black in the footage their Navy had captured was because it was taken on a thermal camera and the plane was hotter than the surrounding area

    He determined the black blob seen by Chilean authorities was just a plane that had just departed from Santiago Airport, and the reason it appeared black in the footage their Navy had captured was because it was taken on a thermal camera and the plane was hotter than the surrounding area

    However, West, thanks to Sitrec, came to a more reasonable conclusion and documented his investigation on YouTube

    He determined the black blob to be a plane that had just departed from Santiago Airport. He claimed the reason it appeared black in the footage captured by the Navy was because it was taken on a thermal camera and the plane was hotter than the surrounding area. 

    'It’s not an intuitive thing, and if you don’t delve too deeply into it, [you’ll be wrong],' West, who programmed Tony Hawk's Pro Series games, told the outlet. 

    As for the streaks the Navy recorded, he explained that these were just the airplane's engines leaving contrails. 

    West claimed that the Chilean Navy also got the flight path wrong.

    'They thought they were looking at an object that was moving left to right.

    'In fact, what they were looking at was this plane, just departed from Santiago Airport that had looped around to gain height over the mountains,' he said. 

    Using his program, he was able to successfully simulate the plane's movements by accounting for the camera angle and matched it to flight records. 

    West thinks his video game programming days helped condition him for the life of debunking UFOs as he spent 'an inordinate amount of time on this trivial little thing, this one intractable little bug that is just causing this problem' during his former profession.

    'It can be very difficult to figure out… but you have no choice,' he told Popular Mechanics. 

    He finds debunking claims of alien sightings has the same rigor as programming a game and tied with his fascination with conspiracy theories, it ignited his passion for investigating UAP. 

    However, other experts remain convinced that UFO activity is real and seemingly has some connection to nuclear sites. 

    The former head of the Advanced Aerospace Threat Identification Program, Lue Elizondo, agreed that there 'seems to be a lot of correlation' between UFO appearances and nuclear sites.

    And independent researcher Robert Hastings, who has been working toward full government disclosure of UAP activity, said in 2010, 'Declassified US government documents and witness testimony from former or retired US military personnel confirm beyond any doubt the reality of ongoing UFO incursions at nuclear weapons sites.'

    Now, new research — in the form of three studies helmed by a retired US Air Force staff sergeant, Larry Hancock, and a data analyst affiliate with Harvard's UFO-hunting Galileo Project, Ian Porritt — shows that not only has there been unusual activity around nuclear weapons and facilities, it has shifted over the years.

    At first seemingly interested in the production of nuclear weapons, UFO sightings later sprang up around silos and bomber bases.

    'You would see this interest at silos when they were being installed before 'the activity would drop off,' Porritt previously told the DailyMail.com.

    Eerily similar to these encounters are the instances of UAPs following fighter jets that were disclosed by the UAP Task Force, including a 'giant Tic Tac' UFO witnessed by Navy veteran fighter pilot Commander David Fravor in 2004.

    Fravor's fellow co-pilot Chad Underwood witnessed the 'perfectly white' wingless oblong captured by his cockpit's in-flight video.

    A fiery explosion of a Space X rocket this week could spell even more misery for the two NASA astronauts stranded in space.

    The unmanned Falcon 9 rocket failed to land successfully after launching satellites into space, bursting into flames before toppling over on its side. 

    This is bad news for the two astronauts that Boeing's faulty Starliner left stranded aboard the International Space Station (ISS) for almost three months.

    Their only hope is to return to Earth on SpaceX's Dragon capsule, which will take off using the Falcon 9 rocket, and is supposed to get them home by February 2025.

    But the latest setback threatens to push that date back even further.

    A full timeline of Boeing's Starliner program, from the singing of their massive contact to the incident that left two astronauts stranded aboard the ISS.

    A full timeline of Boeing's Starliner program, from the singing of their massive contact to the incident that left two astronauts stranded aboard the ISS. 

    The FAA now has to launch an investigation into what went wrong with Falcon 9, which could interfere with SpaceX's rescue mission schedule, and ultimately delay Crew Dragon's launch date significantly.

    'Depending on circumstances, some mishap investigations might conclude in a matter of weeks. Other more complex investigations might take several months,' the agency's website states. 

    What's more, SpaceX plans to use Falcon 9 to launch the Crew Dragon spacecraft, which means the Starliner crew's return to Earth is incumbent upon the booster actually working. 

    But the booster's recent technical issues suggest that a successful launch in September isn't exactly guaranteed. 

    The worst case scenario - a lengthy FAA investigation followed by more issues with Falcon 9 - could delay Crew Dragon's launch even further. 

    NASA will want to be certain the rocket is flawless before allowing it to carry a manned crew, which could mean several more tests between now and that rescue mission.

    SpaceX did not immediately respond to DailyMail.com's request for comment about a time frame.

    NASA astronauts Sunita Williams and Barry Wilmore launched toward the ISS aboard Boeing's Starliner on June 5.

    The scandal-laden Starliner - which was built and developed using over $4 billion of taxpayer money - had been plagued by helium leaks and thruster issues in the weeks leading up to launch, and even on the day of. 

    The spacecraft safely delivered Williams and Wilmore to the ISS, but by the time it got there, it had sprung more helium leaks and five of its 28 thrusters had failed.

    Boeing's Starliner spacecraft was plagued by technical issues even before in launched on June 5. NASA ultimately deemed it unsafe to return its crew to Earth.

    Boeing's Starliner spacecraft was plagued by technical issues even before in launched on June 5. NASA ultimately deemed it unsafe to return its crew to Earth. 

    Williams and Wilmore were originally supposed to spend only eight days on the ISS, but the technical issues with their spacecraft have left them stuck up there for nearly three months now. 

    In a press conference on August 24, NASA officials announced that it would be too risky to bring the astronauts home on faulty Starliner. 

    Instead, they will return home on SpaceX's Crew Dragon spacecraft, which is scheduled to launch NASA astronaut Nick Hague and Russian cosmonaut Aleksandr Gorbunov toward the ISS on September 24, according to a NASA statement released today. 

    The means that Williams and Wilmore will remain on the ISS until February 2025 at the earliest. 

    The decision was humiliating for Boeing, which has struggled for years to get their Starliner program off the ground only to be bailed out at the eleventh hour by their biggest competitor. 

    'We have had so many embarrassments lately, we're under a microscope. This just made it, like, 100 times worse,' one employee anonymously told the New York Post. 

    'We hate SpaceX,' he added. 'We talk s*** about them all the time, and now they're bailing us out.'

    At this point, it's unclear whether Starliner will ever be able to complete a crewed mission to the ISS.  

    NASA is planning to decommission the ISS by 2030, giving Boeing just five years to fix Starliner's technical issues and successfully send and return astronauts to space.

    To put that in perspective, it's already been five years since Starliner's first failed uncrewed test flight. 

    But it's possible that Boeing could retire Starliner before they even hit that deadline, as the company has already sunk $1.6 billion into the spacecraft's development.

    The Falcon 9 booster failed after a successful launch from Cape Canaveral Florida early Wednesday morning as part of a mission to deliver 21 Starlink satellites to low-Earth orbit. This was the rocket's 23rd launch. 

    The launch went smoothly, and the booster was able to separate from the upper stage before beginning its return to Earth. But it was all downhill from there. 

    The first stage of the Falcon 9 rocket failed to properly land on its intended target: an uncrewed drone ship named 'A Shortfall of Gravitas.' 

    Instead, the booster exploded into flames and then tumbled onto its side. 

    Although the overall mission was a success, the Federal Aviation Administration has halted any more Falcon 9 launches until it determines the cause of the mishap.

    'A return to flight of the Falcon 9 booster rocket is based on the FAA determining that any system, process or procedure related to the anomaly does not affect public safety,' FAA officials said in written statement.

    This is the second time the FAA has grounded Falcon 9 in the last two months. 

    The agency halted Falcon 9 launches for two weeks in July after one of the rocket's  upper-stage liquid oxygen tanks leaked, preventing a batch of satellites from deploying properly and causing them to burn up in Earth's atmosphere.

    It's unclear how long this new investigation will take. In the meantime, a crew of four SpaceX astronauts awaits the launch of the Polaris Dawn mission, in which Falcon 9 will carry them to orbit for five days. 

    The mission, funded and crewed by entrepreneur Jared Isaacman, is expected to make history by reaching higher altitudes than humans have traveled since NASA's Apollo program in the 1970s, and performing the first commercial spacewalk. 

    Life on board the ISS is very cramped, and astronauts Barry Wilmore (left) and Sunita Williams (right) will endure another six months on board

    But Polaris Dawn has already been delayed several times due to unfavorable weather conditions and technical issues. It was originally scheduled to launch on Tuesday.

    Friday would have been the earliest date that Polaris Dawn could launch, but the FAA's investigation has now put the mission in limbo. 

    As for the stranded Starliner crew, they'll just have to hope that the FAA investigation drag on, and that Falcon 9 successfully launches the Crew Dragon mission in September. 

    Meanwhile, Boeings Starliner is set to return to Earth uncrewed on September 6, according to NASA. 

    NASA officials have reported that the astronauts are 'doing fine' and keeping busy with day-to-day tasks and science experiments. 

    But it's only plausible that they're feeling some frustration after a mission that was supposed to last about a week transformed into an eight-month-long nightmare.
