James Webb has had to investigate whether he was born “from the top down” or “from the bottom up”

by

29 Cygni b is a huge celestial object, with a mass equal to 15 times the mass of Jupiter. Apparently it is a planet, but that mass could place it as a star. For example, a brown dwarf. Therefore, a team of astronomers has used the James Webb to analyze its origin, further refining the concept of the formation of stars and planets. A question of metals. The authors of the study, who it was just publishedhave used the NIRCam camera on the James Webb Space Telescope to take photographs of this planet. This instrument allows high-resolution images and spectroscopy measurements to be taken, with which the composition of the atmospheres of stars and planets can be studied, taking into account how they reflect light. Thanks to this, it has been seen that 29 Cygni b is very enriched in metals compared to the star around which it is located. Specifically, it has an amount of metals equivalent to 150 Earths. This is compatible with the accretion of a large amount of metal-laden solids into a protoplanetary disk. It is then confirmed that it is a planet, but a planet very unusual. Planet or star? That’s the question. Planet formation takes place in a bottom-up process. In a disk of gas and dust, known as a protoplanetary disk, dust particles collide to form small fragments of rock and ice, which continue to clump together and grow until they form a planet. It is a process called accretion. The largest ones, in addition, in this process capture gas, which is why they later become gas giants. On the other hand, stars form from top to bottom. A gas cloud fragments and each fragment collapses under its own gravity, becoming smaller and denser. From paradox to paradox. This definition could lead us to think that planets are larger than stars. After all, planets go from less to more and stars from more to less. However, that is not true. Stars form when huge clouds of gas collapse, so they are still very massive. So much so that nuclear fusion can occur in them due to the high conditions of pressure and temperature. On the planets, although there is a growth from less to more, it is not so great. The problem is that with planets as immense as 29 Cygni b there are doubts about the formation from less to more. It would seem that they were also formed by a fragmentation process in protoplanetary disks. As explained by the European Space Agency in a statementis something that “could explain why some very massive objects are found billions of kilometers from their host stars, in regions where the protoplanetary disk should have been too weak for accretion to occur.” That’s just what happens with 29 Cyni b. It has an enormous mass and is 2,400 kilometers from its star. What James Webb teaches us. The fact that 29 Cygni b is so rich in metals indicates that it must have been formed by an accretion process, in which it accumulated more and more. In fact, heIt is normal for a planet to have many metals in proportion to its starwhich happens in the system in which 29 Cygni b is located. In short, it is shown that much larger planets than we thought can be formed by accretion, without having to resort to a top-down process. And now what? 29 Cygni b has been the first of the four objects that will be studied by James Webb. All of them have a mass between 1 and 15 times that of Jupiter and are at least 1.5 billion kilometers from their star. This indicates that they are all in that dilemma of being huge planets or another star. Cataloging them into one of the two groups can help us understand much better the process by which the largest planets are formed. Image | NASA, ESA, CSA, J.

James Webb has bad news for the largest natural laboratory for rocky planets, but there is still some hope

by

The star TRAPPIST-1 and the seven known planets that surround it are a natural laboratory in which the evolution of rocky planets can be studied. This has led many scientists to focus their attention on them, in search of a possible habitable planet. However, observations made by an international team of astronomers with the help of the James Webb Space Telescope They are not very encouraging. Planets without atmosphere. The James Webb Space Telescope has a very powerful infrared radiation analysis instrument, with which it can analyze the temperature of the planets it observes. These emit infrared radiation whose intensity is proportional to their temperature, so a thermal map can be made. That’s what these astronomers have done. They have initially focused on two of the planets that orbit TRAPPIST-1: TRAPPIST-1a and TRAPPIST-1b. The resulting heat map shows that neither planet has an atmosphere. They may have had it one day, but possibly TRAPPIST-1 itself destroyed it. It is a very uninspiring result for the search for habitable planets in this system. Lights and shadows of TRAPPIST-1. So far seven exoplanets have been discovered orbiting TRAPPIST-1. They are all very close together. In fact, its seven orbits are concentrated in the distance between Mercury and the Sun. What happens is that this red dwarf is less energetic than our Sun, so the temperature would not be as suffocating. All of these planets are rocky, like Earth, and in fact, some are very similar in size. There could be an exoplanet with conditions similar to ours. The problem is that red dwarfs They emit a lot of radiation and energetic flows of particles that could destroy their atmosphere.. And of course, without atmosphere, there is no life. Tidal lock. All planets in the TRAPPIST-1 system are tidally locked. This means that its rotation and translation period around the red dwarf they are synchronized. As a result, there is one side continuously exposed to the star and another on the opposite side. On one side it is always day and on the other it is always night. NASA/JPL-Caltech Extreme temperatures. When a planet is tidally locked, there can be two situations, depending on whether it has an atmosphere or not. When there is an atmosphere, heat flows from the light side to the dark side, so that the entire planet has a stable average temperature. On the other hand, if there is no atmosphere, the dark side can be frozen and the illuminated side can be scorched. In the two exoplanets analyzed by James Webb, it has been seen that temperatures are around 100ºC-200ºC on the illuminated side and -200ºC on the dark side. Therefore, it is confirmed that there is no atmosphere. And now what? Despite this hard blow, there is still hope. The two exoplanets that have been analyzed are not in the star’s habitable zone. This is the distance from it at which the temperature is adequate for the water, if any, to remain in a liquid state. At that exact point there are only TRAPPIST-1e, TRAPPIST-1f and TRAPPIST-1g. Furthermore, the former has a density and size very similar to those of Earth. James Webb has all his attention on this exoplanet right now, to repeat the process. If there were an atmosphere on it, it could still remain on the list of possible habitable planets. It’s still interesting. Despite the first blow, TRAPPIST-1 remains a very interesting system for understand the evolution of rocky planets. The Earth was lucky not to lose its atmosphere; but, beyond those, the evolutions can be similar. Furthermore, we have not yet ruled out that TRAPPIST-1e has an atmosphere. Let’s go step by step.

The James Webb Telescope has finally discovered Saturn’s best kept secret

by

Saturn has become a headache for scientists since the Cassini probe in 2004 took action of its rotation speed that did not coincide with the figures accepted in the scientific community. Little by little, new data has been discovered that helps explain this inconsistency, but it has been necessary for the James Webb Space Telescope to come into play to find the definitive answer. Cassini’s incoherence. In 2004, the Cassini probe took advantage of its visit to Saturn to measure some important dataas its rotation speed. Normally this is calculated by analyzing parameters that occur periodically, such as radio emission pulses. It is a very consolidated method, which has been used to calculate the rotation rate of many planets. With Cassini, it was expected to obtain a figure that would coincide with what the Voyager 2 probe had previously taken in 1981. However, to the surprise of the scientists who studied the data, the numbers didn’t add up. A mysterious push. A planet cannot speed up or slow down without an external force driving it. There should be something driving those changes in rotation speed. Or, at the very least, some unknown factor that was falsifying the results. All this was a mystery until 2021, when a team of scientists from the University of Leicester published a study in which new clues were provided. The auroras enter the scene. For a month, scientists at the University of Leicester measured infrared emissions in Saturn’s upper atmosphere. This allowed them to map a series of variable fluxes of activity in the ionosphere, the layer of the atmosphere in which ionized particles are abundant. That is, atoms that have gained or lost electrons and have acquired a negative or positive charge, respectively. These flows were related to the formation of auroras. However, there was something strange. Unlike on other planets, including Earth, a good part of these auroras were produced by the action of rotating winds within Saturn’s own atmosphere, not only by the influence of the magnetosphere. A reminder about the auroras. The auroras are formed when charged particles interact with the atoms that make up a planet’s atmosphere, exciting them and causing the emission of light. Normally, these charged particles come from solar activity, as happens on Earth, or from volcanic eruptions on nearby moons, as happens on Jupiter. Be that as it may, they are concentrated in a region external to the planets, known as the magnetosphere. In the case of Saturn, the 2021 study showed that auroras were also forming within the planet’s own atmosphere. On Earth, auroras are formed by solar activity A puzzle still incomplete. The interaction of molecules and atoms in the atmosphere with charged particles does not only cause the emission of light. It also causes the emission of radiation in other regions of the spectrum. For example, radio pulses. Let us remember that these pulses are the ones that were used to measure the rotation of Saturn. The auroras could be falsifying them. These auroras, as we have seen so far, are produced by the action of rotating winds in Saturn’s own atmosphere. But where do those winds come from? The rock star arrives. The James Webb Space Telescope is the rock star of space telescopes. A state-of-the-art instrument, capable of reaching where other telescopes could not. Therefore, thanks to him, the necessary measurements could be taken to find the origin of Saturn’s winds. Specifically, it has captured the glow caused in the infrared by a molecule in Saturn’s upper atmosphere, called trihydrogen cation. This is very useful, because it acts as a kind of thermometer. It is very susceptible to environmental conditions, so its ionization state helps to know the surrounding temperature. By carefully analyzing its state in different regions of Saturn’s northern hemisphere, it has been possible to make a map of both temperatures and particle density. The missing piece. The temperature and particle density patterns match those predicted in a series of computer models 10 years ago. In these models, these patterns originated when the auroras themselves acted as a heat source. The endless cycle. What happens is this: the auroras, with all their display of light and radiation, heat the atmosphere at a specific point. This heating causes the movement of particles between points at different temperatures, generating a wind charged with electricity. This wind, in turn, propels electrically charged particles, which cause more auroras to form. It’s a vicious circle or, as the authors of the study explaina planetary heat pump. A perfect system that feeds itself. And, of course, the mysterious external factor that upset scientists trying to measure Saturn’s rotation.

The chemical composition of galaxies has always been full of unknowns. James Webb has taken a huge step to solve it

by

The James Webb Space Telescope sees where others can’t: its infrared vision pierces clouds of cosmic dust and reaches galaxies so far away that it took billions of years for its light to reach us. Looking far into space is, in that sense, looking back in time. However, what James Webb has seen in these galaxies differs from what was expected: these early galaxies seem to have too much nitrogen, much more than expected. Among the exotic possible explanations of science, hypotheses such as gigantic stars never seen before, black holes functioning as catalysts for galactic chemistry or large quantities of stars have passed. In fact, that was the topic of conversation in the middle of a phone call while Mexican astrophysicist José Eduardo Méndez-Delgado waited in line for the doctor. On the other end of the line, his colleague Karla Arellano-Córdova, who was in Edinburgh. In that informal talk they decided to change the prism: perhaps the problem was not the galaxies, but how we measure them. The discovery. The proposal from this international team is to analyze three light signals from the same oxygen ion to calculate temperature and density at the same time, without starting from one to calculate the other (the original source of error). The result: the gas was a hundred or a thousand times denser than was assumed in those galaxies. With that correction, the galaxies turned out to be richer in metals than they appeared and the excess nitrogen was drastically reduced. Why it is important. First, because the metallicity of a galaxy is directly related to its history: the more metals there are in its composition, the more stars have been born and died within it. Until now we were underestimating this figure, which made those early galaxies appear very different from our own and suggested a sharp and discontinuous evolution. Now they look more like what we know. But the elements essential for life, such as carbon, oxygen or nitrogen, did not exist when the universe was born: they were manufactured by the stars inside and expanded when they died. Hence the interest in knowing the chemistry of galaxies: it helps to understand when the universe had the necessary ingredients for life. With the wrong measurements, we don’t know if those ingredients were there earlier and in more places than we thought. Context. The standard method to know the composition of a distant galaxy is to analyze the spectral lines of its light based on the density of the gas and its temperature. The problem is that in these primitive galaxies the gas is much denser than expected, so its application as a thermometer works poorly. And from here on, everything failed. The nitrogen anomalies appeared in the first scientific data from the James Webb Space Telescope, as this either this. Since the results did not fit the models, the scientific community threw itself into trying to find explanations. This paper proposes to take a step back: before interpreting stellar physics, check that the measurements are correct. Besides, the Webb now allows it: simultaneously detects oxygen lines in the ultraviolet and in the optical in such distant galaxies. How they do it. In essence, the trick is choosing the right signals. One of the oxygen light lines, visible in ultraviolet, has a special property: it does not distort even if the gas is very dense, something that happened with the lines they were using previously. By combining it with two other signals from the same atom, the research team can calculate temperature and density at the same time, as if they were solving two simultaneous and independent equations. Using statistical simulations, the team found that the results were consistent with other independent measurements of the same galaxies. Yes, but. As the team explains in the work, their method corrects the density error, but not other possible errors that are equally important: the gas of these galaxies also has internal temperature variations, and that can bias the results in ways that this study does not resolve. Furthermore, the method only works well when all three light signals from oxygen are clearly detected. In three of the six galaxies analyzed this was not possible, and the results are less precise. Nitrogen remains a problem. The overabundances come almost entirely from a particular ion whose emission is extraordinarily sensitive to temperature: a variation of just ten percent in that parameter would reduce the calculated nitrogen by half. No one has yet measured that temperature directly. However, it points out a path to follow before looking for “exotic” explanations: verify that the measurement tools are up to par.

He has achieved it by combining James Webb and Hubble

by

There are images that do not need context to impose themselves. Saturn is one of them. It is enough to see it to understand why it continues to be one of the great protagonists of the solar system: for its shape, for its rings and for that mixture of apparent simplicity and complexity that it hides. The same thing happens to many of us, we stop at any new photograph as if it were the first. And that is somewhat logical, because we do not always have the opportunity to observe it with a such a rich comparison between visible and infrared light nor to get closer, even through an image, to what really happens in its atmosphere. On this occasion, what NASA has shown It is not simply a new photograph, but a different way of observing the same planet. In a single comparative image (Click to download the image in high definition), the agency has put together an observation from Hubble taken on August 22, 2024 and another from James Webb captured on November 29 of the same year, 14 weeks apart. The result is a double view that seeks not so much to impress as to explain how what we see changes when we observe at different wavelengths. What are we really seeing in this image? If we stop at the image, the difference is obvious from the first moment. On the left, the James Webb shows a Saturn with darker, more contrasting tones, where the rings shine brightly because they are made of highly reflective water ice. On the right, Hubble offers a view much closer to how we would perceive it with the naked eye, with soft colors and more subtle bands. According to NASA, both telescopes are observing sunlight reflected by the clouds and mists of the planetbut each one does so in different ranges, which radically changes the information they provide. On the left, the image of Saturn captured by the James Webb Space Telescope; On the right, the one obtained by the Hubble Space Telescope: two views that reveal its active atmosphere, its moons and its bright rings Beyond the visual contrast, this comparison allows us to peek into what happens inside Saturn’s atmosphere. The agency explains that by combining both observations, scientists can study the planet at different altitudes, from the deepest clouds to the highest and most diffuse regions. In the Webb image, for example, a long-lasting jet stream known as a “ribbon wave” appears and also a persistent remnant of the great spring storm of 2010 to 2012. Hubble, for its part, provides continuity in monitoring the bands and the general evolution of the planet. At this point, it is worth clarifying something important: we are not looking at two photographs that reproduce Saturn in the same way. The difference is in how the light is collected and interpreted. Hubble works in the visible spectrum, the same one our eyes perceive, which is why its image is more familiar. James Webb, in this case, observes in the infrared, a radiation invisible to us which allows detecting clouds and compounds at different depths in the atmosphere. In order to display this data, scientists translate these signals into visible colors, and from there come the unnatural tones that appear in your image. If we move all this to a closer scene, the most reliable reference would be the Hubble image. That is the closest thing to how we would perceive Saturn, with soft tones, not very marked bands and bright but natural rings. But the interesting thing is not to choose between one or the other, but to understand what each look contributes. Webb’s allows us to go beyond the visible and detect processes that would otherwise remain hidden. And it is precisely in that combination where this image gains all its meaning.

James Cameron has always played heads or tails with his films. Cinema has returned him a fortune of 1.1 billion

by

Imagine shooting movies that cost hundreds of millions, dive into the impossible and play it all on one card: that the public likes them. James Cameron has done it for four decades and that bet on heads or tails in each film has helped him enter a select club: that of the billionaires list Forbes. At 71 years old, the director of titles such as Titanic and Avatar has achieved an estimated net worth of $1.1 billion, thanks to a balance between box office revenue, profit-sharing agreements and the exploitation of licenses for his most profitable franchises. Some hard beginnings. Cameron’s path was neither immediate nor easy. Before becoming a successful name in Hollywood, he worked as a truck driver and production assistant with modest salaries. His first feature film as a director, ‘Piranha II: The Vampires of the Sea’ in 1982. A creative setback that hardly brought him any income, but it helped him gain a foothold behind the cameras. The real turning point in his career came with ‘Terminator‘ in 1984. The filmmaker claimed that he had dreamed the apocalyptic story during a feverish night and, to ensure creative control, he sold his script for one dollar, a bet that resulted in a “low-budget” film ($6.4 million), but which represented a return of $78 million at the box office and the definitive boost for his career as a director. There is no easy movie: everything is heads or tails. Camerón risked his salary to carry out the project the way he wanted, and he came out of that adventure very well. That triumph led him to continue risking immediate benefits in exchange for control and participation in future income. In ‘Risky lies’the director went overboard with the production budget, becoming the first film to exceed $100 million. To avoid ceding creative control, Cameron renegotiated his agreement with FOX, allowing the studio to recoup its investment by ceding part of its profits to him. Finally, it was not necessary since the film grossed $378 million worldwide. Another example of this dynamic was ‘Titanic. When the budget exceeded $200 million, Cameron voluntarily gave up his salary as director and producer. The studio, resigned to rising costs, prepared for a financial debacle. However, the result was a success that grossed more than $1.8 billion at the box office and more than $800 million in VHS sales, making Cameron one of the highest-paid filmmakers of his generation after receiving a percentage of the profits. Avatar and his great gold mine. However, despite having a track record full of titles that are already part of the history of cinema, its real gold mine It’s the saga ‘Avatar‘. The first film, released in 2009, grossed nearly $3 billion worldwide and generated more than $350 million directly for Cameron from its box office rights, physical sales and licensing fees. Your producer, Lightstorm Entertainmenthas contributed to his fortune with parallel income derived from the saga through theme parks, merchandising and technological agreements. The sequel’Avatar: The Sense of Water’ It totaled more than 2.3 billion at the box office, with Cameron obtaining around 250 million dollars for its box office and production rights. Just a few days before the premiere of the third installment with ‘Avatar: Fire and Ashes’Forbes already takes its box office success for granted and estimates that Cameron could add at least $200 million more to his pre-tax assets if the film meets commercial expectations, as it did. the second installment of the saga. A legacy that goes beyond money. Throughout his career, Cameron has been known for both his perfectionism and his willingness to give up short-term benefits in order to maintain creative control or improve the end result. That approach has led him to technological and business projects outside of cinema: from immersion in digital effects with ‘Terminator’, to underwater exploration after ‘Titanic’ and the environmental activism at the end of the first installment of ‘Avatar’. Cameron doesn’t usually talk about wealth. In a recent interview with Puck, the director said that “I wish I were a billionaire.” According to Forbes, his salaries as a director, participation in the profits of his productions, income from theme park and toy licenses and the value of his production company, raise James Cameron’s fortune to over $1.1 billion. At least until the premiere of his new installment of ‘Avatar’.

James Webb has opened the door to a fascinating world

by

Until not so long ago, the word “exoplanet” seemed more typical of speculation than astronomy. Isaac Newton already dropped in the ‘Scholium Generale‘ of the Principia Mathematica that fixed stars could be the center of systems similar to ours, but science needed centuries to prove it. It was not until the late 1980s that the first signs of planets outside the Solar Systemalthough we had to wait until 1992 to confirm for the first time the existence of worlds beyond the Sun, around the pulsar PSR B1257+12. In recent decades, the pace of discoveries has skyrocketed thanks to increasingly precise instruments, which have allowed us to locate worlds that are as strange as they are fascinating. The Kepler space telescopefor example, identified more than a decade ago Kepler-16ba planet with “two suns” reminiscent of Tatooine from Star Wars. Since then we have cataloged a huge variety of exoplanets, but now the James Webb telescope presents an especially striking find: a world of boiling lava that, to the surprise of astronomers, is colder than theoretical models predict. An extreme world that questions what we know With a radius approximately 1.4 times that of Earth, TOI-561b It is an extreme super-Earth that orbits a star located about 280 light years away, in the constellation Sextans. NASA describes it as the innermost planet of a system made up of four worlds, with an immediate peculiarity: it completes an orbit in less than eleven hours. Its proximity is so extreme, barely 0.01 astronomical units, that the daytime hemisphere must greatly exceed the melting point of rocks. Everything points to a planet trapped by its star in a tidal lock, with eternal day on one side and perpetual night on the other. One of the peculiarities that most puzzles researchers is the low density of TOI-561 b. Astronomer Johanna Teske, lead author of the study, explains that “it is not a super-puff, but it is less dense than one would expect with a composition similar to that of the Earth.” The team envisioned the planet having a small iron core and a mantle made up of less compact minerals, a possibility that would fit the chemistry of its star. As it is a very old G-type star, about 10 billion years old and poor in iron, located in the thick disk of the Milky Way, it is plausible that the planet emerged in a primordial environment different from that of the Solar System. Still, the exotic composition did not resolve all the unknowns, and the team began to consider another possibility: that TOI-561 b was involved through a thick atmosphere. The idea is striking because the models indicate that small planets subjected to such intense irradiation for billions of years should have lost their gases long ago. NASA reminds us, however, that some worlds of this type show signs that they are not simple bare rocks. That nuance opened the door to thinking that the low density could be due, in part, to a volume inflated by a substantial layer of gases. To test the idea of ​​a dense atmosphere, the team turned to a technique that James Webb has used on other rocky worlds: measuring the disappearance of some of the infrared glow as the planet passes behind its star. Using the NIRSpec spectrograph, the researchers estimated the temperature of the illuminated hemisphere and compared it to what would be expected for a surface without heat-distributing gases. If TOI-561 b were a bare rock, its temperature would be around 2,700 ºC. However, observations placed that value close to 1,800°C, a difference too large to ignore. The unexpectedly low temperature makes sense if TOI-561 b is enveloped by a dense, volatile-filled atmosphere. In that case, the winds would transport heat from the illuminated hemisphere to less hot areas, which would reduce the infrared emission received by the telescope. Gases capable of absorbing part of the radiation before it escapes into space also come into play, something that coincides with the models evaluated by the team. YoIt is even possible that silicate clouds exist that reflect the light of the star and contribute to cooling the upper layers of the atmosphere. To explain how TOI-561 b maintains such a resilient atmosphere, the researchers propose a mechanism in which magma and gases are in constant exchange. Tim Lichtenberg points out that as the interior releases volatile compounds into the atmosphere, the ocean of molten rock recaptures some of them, reducing the loss to space. This process requires a planet exceptionally rich in volatile substances, very different from Earth in its initial composition. In Lichtenberg’s words, it would be “like a ball of wet lava,” a description that well sums up the extreme nature of the find. The observations that have allowed us to reconstruct this scenario are part of James Webb’s General Observers 3860 program. For more than 37 hours, the telescope continuously tracked the system as TOI-561 b completed nearly four full orbits, a record that offers a rare glimpse of how its brightness varies along the way. With that volume of data, the team is now analyzing how the temperature changes around the planet and what clues it provides about the composition of its atmosphere. This set of data, still being analyzed, points to a more complex world than was intuited in the first observations. The case of TOI-561 b shows that even the most extreme worlds can hold surprises. Far from just a scorched rock, Webb’s observations describe a dynamic system in which magma, atmosphere, and stellar radiation interact in ways we don’t yet fully understand. As Johanna Teske points out, “What’s really exciting is that this new data set It’s opening even more questions than it’s answering.“The research continues, and each new analysis seems to confirm that this planet belongs to a category that we are only beginning to know.

James Bond is literally dead. And apparently that’s a problem for his next movie.

by

James Bond has not been an easy franchise for years, decades perhaps. The latest incarnation of 007, played by Daniel Craig, took a turn from the classic incarnation of the character, ending in 2021 in ‘No time to die‘ and tragically. Now that Amazon owns the rightsis encountering a considerable obstacle to launching a new installment. He died. The death of James Bond in ‘No Time to Die’, the last incarnation to date of the character, has generated an enormous creative challenge for Amazon MGM Studios, current owners of the rights. For the first time in sixty years, 007 died on screen after a missile attack and poisoning by nanobots. Now Steven Knight, creator of ‘Peaky Blinders’must find a way to continue the franchise while respecting that final death. What seemed like a bold ending has become the biggest obstacle to Bond’s future. Dead end. According to sources close to the production, the franchise’s producers are “pulling out hair“because Bond did not disappear or fake his death, as he has done in other installments. He was literally torn to pieces before the viewer. To Anthony Horowitz, author of three recent Bond novels, It is not difficult to believe in these difficulties: “The last time we saw Bond he was poisoned and torn to pieces. It was a mistake, because Bond is a legend.” Why is it a problem? There are authors who talk about the fact that a death scene as explicit as the one seen in the latest Bond film undermines the legendary nature of the character, who has lived an impossibly long arc of time (he fought in the Second World War, but remains fit today) and has changed his face as his performers rotated. This gives 007 a halo of a mythological hero, in the style of the classics, which clashes head-on with the idea of ​​him dying. Furthermore, it is a decision with an economic ingredient: a reboot It would open the door to continuous and unconnected versions, which would devalue the brand. We must bear this death. Where is the franchise? There is still little known information about this new installment: Denis Villeneuve, director of ‘Dune’, will direct this twenty-sixth Bond adventure, with Knight as screenwriter. In March 2025, Amazon MGM obtained complete creative control of the franchise after an agreement with Barbara Broccoli and Michael G. Wilson, ending decades of control by the Broccoli family, and the studio aims for a premiere in 2028. Casting is paralyzed until the problem of Bond’s death is resolved, but names like Tom Holland (finally discarded), Jacob Elordi and Aaron Taylor-Johnson (also discarded). Possible solutions. With the franchise in danger, many fans and experts have provided possible solutions. The first is an idea that has always been floating around since it became clear that the character’s longevity was meaningless: “007” and “James Bond” are code names given to the best agent, and when one dies or retires the next one receives the title. Of course, there is the possibility of a complete reset. You can also propose a prequel and set the film, for example, in the sixties, showing Bond’s rise in MI6. EITHER use the already canonical character of Mathildethe daughter that Bond has with Madeleine Swann in ‘No Time to Die’, and changing the character’s gender.

Ukraine has a weapon against Russia that we had only seen in James Bond. Her name is Sea Baby and when she finishes her work she blows herself up.

by

At the end of September Ukraine sent a message: It was already the largest drone laboratory on the planet, but with its latest 12-meter “monster” it wanted to do the same under the sea. This is how the family of Toloka underwater dronesa technological leap that redefined naval warfare in the Black Sea. That effort now has its continuation in a drone that until recently we had only seen in James Bond movies and the like. Technological evolution. Ukraine has taken its “Sea Baby” naval drones from being disposable explosive boats to becoming attack and multiple mission platforms capable of operating at more than 1,500 kilometers, transporting up to 2,000 kilos and mount heavy telecontrolled weaponry (multiple rocket launchers, stabilized turrets, secondary drone launch) while incorporating self-destruct systems to avoid capture and AI-assisted functions to reduce identification errors. This step not only adds firepower and range, but turns a low-cost means into a sustained system that can penetrate, hit, return and remain available (or self-destruct), something that repositions the naval drone from immediate consumption to renewable operating capital. The Black Sea. Successive waves of drones have forced Russia to withdraw most of its fleet from Sevastopol to Novorossiyska change in posture that does not respond to a specific defeat but to that persistent risk that makes it unfeasible to sustain an advanced presence without assuming continuous losses. The “Sea Baby” have been attributed by the SBU to eleven attacks against shipsas well as repeated blows against the Crimean bridge and other logistics facilities, producing a chain effect: Moscow has had to redirect its military transport to land and more distant ports, making each kilometer of support more expensive and reducing its ability to condition Ukrainian trade routes to Europe. Doctrinal change. What once required steel fleets, shipyards and squadrons can now be inflicted with platforms cheap, reproducible and guided at a distance, which modifies the unspoken rule that the maritime domain belongs to the one who owns tonnage: here control emanates from who can inflict repeated damage at a lower cost than that imposed on the defender. The Ukrainian case surpasses precedents such as the coastal missiles of the Lebanon in 2006 because it not only denies a coastline, but forces a structural reconfiguration of an entire squadron and its main base, demonstrating that an entire naval theater can be altered without having a conventional navy. Industry and allies. kyiv claims to produce around 4,000 naval drones and needing only half for his own defense, opening the door to sell the surplus to partner countries while NATO observes and adjusts doctrine after verifying that these systems have changed the cost/effect relationship at sea. Public financing via United24 and coordination with political and military command make the program an example of how a country at war can generate dual technology with external projection, replicating what happened with aerial UAVs: first combat effectiveness, then international adoption and doctrinal adjustment by third parties. Consequences and cycles. There is no doubt, offensive success is strong now defensive investment: floating barriers, sensors, redundant electronic warfare and point defense layers in ports and terminals to prevent innovation that has worked externally from reversing its own infrastructure. Russia tries to copy these platforms and use them againwhat chains a cycle of innovation in the face of interference that pushes both sides to adapt communications, navigation and mission architecture to overcome the electronic blockade. The result: a loop of accelerated evolution in which the advantage is no longer in possessing an isolated weapon, but in the ability to continually improve it before the opponent degrades its effect. Strategic conclusion. The Ukrainian naval drones have shown that sea power can be eroded without a conventional fleet through cheap mass, strategic reach and sustained pressure on valuable nodes, altering the adversary’s posture and reallocating its resources on the defensive. The displacement of the Russian fleet, the logistical impact and the international adoption as a reference point to a change of era: the sea ceases to be a domain secured by the capital spent on steel and becomes a space where the advantage belongs to whoever controls the marginal cost of the next impactnot the size of the hulls it anchors.

The James Webb captures a lonely object of the size of Jupiter devouring like a miniature sun

by

An international astronomer team has witnessed an extraordinary event: a lonely object, with a mass of just 5 to 10 times that of Jupiter, has entered a violent and prolonged growth burst. Using the combined power of James Webb Space Telescope (JWST) and him Vary Large Telescope (VLT) of the Southern European Observatory, scientists They have observed How this object, known as Cha J11070768-7626326, drastically increases its brightness and its “food” rhythm, behaving like a miniature star. The importance. This discovery represents the first time that a outbreak of accretion of type “exor”, a phenomenon so far associated with young stars, in a body of planetary mass. The finding is not only a milestone in astronomical observation, but also further blur the borders between what we consider a giant planet and a small star. The mystery. CH 1107-7626 is not a planet in the traditional sense that we all have in our mind. Although it has a mass comparable to that of a gaseous giant, I do not orbit any star and is 620 light years from the earth. Is what is known as an “free planetary mass object” or FFPMO (for its acronym in English). The existence of these lonely bodies raises a fundamental question for astronomy: are giant planets that were expelled from their solar systems, or are smaller stars that can exist in isolation? In order to solve this enigma that astronomers have right now on the table, you have to analyze the gas and dust disc that is around, as well as the way of accumulating the material. The fact that Cha 1107-7626 has an album and feeds on it suggests that its origin is more like that of a star. A cosmic feast. Astronomers observed Cha 1107-7626 in a state of calm in April and May 2025. However, for June, something had changed drastically. The object entered a “indulgence.” This means that its rhythm of ‘food’ began to increase, and in this way it reached a mass increase rate of 10-7 masses of Jupiter per year, the highest ever measured in a planetary mass object. As a result of this frenzy, the objective became between 1.5 and 2 brighter magnitudes in visible light and its optical flow increased between 3 and 6 times. This outbreak remained active for at least two months, since it was still on the end of the observation campaign in August 2026. But the most interesting thing is the speed it has. According to the observations made with the Vray Lark Telescope of the European Observatory, the growth rate is really aggressive, with a record rate of devouring 6,600 million tons per second of dust and gas. Great footprints. Beyond the increase in brightness, the telescopes captured detailed physical changes that reveal the nature of the event. A hydrogen emission line, known as Hα, developed a “double peak” profile with a red displaced absorption. According to the authors, this profile is a “distinctive brand” of the accretion channeled through magnetic fields, a process called “magnetospherical accretion” observed in young stars. But the most surprising finding was the change in the chemistry of the disc. At first, changes in the emission lines of the hydrocarbons molecules that came from the disc during the outbreak were seen. But water vapor also began to appear with a characteristic emission around 6.6 µm. This appeared during the outbreak where there was nothing before and is relevant because it is the first time that chemical changes of this type are observed caused by an increase in accretion. Relevance. This event classifies Cha 1107-7626 as the first “exor” of known planetary mass. Exor outbursts are significant accretion events that are considered key episodes in the early evolution of the stars. They can deeply affect the physical structure and chemical composition of the protoplanetary disk, potentially influencing the early stages of planet formation. Observing this process in such a small object demonstrates that the violent and fundamental mechanisms that the stars build also work at planetary scales. The study of Cha 1107-7626 offers an unprecedented vision of the accretion in the lower mass objects of the universe, providing a new window to understand how both smaller stars and the largest planets are formed.
