While the Portuguese enjoyed sun eclipse, their electrical system had a really bad time

by

Last Saturday, March 29, a partial solar eclipse It was visible in the Iberian Peninsula in the morning. A phenomenon that entertained more than one in this first spring mornings. However, for our Portuguese neighbors it has been a problem for their electricity grid. The absence of the star. During the two hours of eclipse, Portugal lost 560mw of solar generation, which is equivalent to 23% of the country’s electricity production at that time, according to national electrical networks (REN). An imbalance. Solar energy suffered A drop in electricity generation During the astronomical phenomenon, but it was a loss that occurred progressively, approximately 10MW per minute. This situation led to a decline of 8.5% of the electrical production of total consumption, how has expressed a press release THE REN. Return to normal. From 11:30, solar production began to recover at a faster rate, 22MW per minute until it reached its normal intensity. However, the fall was greater than the answer, although it turned to other sources such as hydroelectric and thermal. The balance attempt. Last year, the Portuguese country reached historical records with renewables, covering up to 90% of your demand. However, the eclipse evidenced Portugal’s problem with the storage of energy in batteries and its energy dependence with Spain, how It is observed in the daily balance. An affected interconnection. The eclipse also had an impact on Spain, which ends affecting interconnection Between both countries. At the broader level, the Entso-E network And European Transmission Systems (OST) operators They registered A loss of generation of approximately 21,000 MW during the event. To minimize the impacts, the electric operators of several countries, including Portugal and Spain, they worked together through the service of Short-Term Adequacy (STA)which allows to plan and balance generation and consumption in a seven -day window. Was the impact here very big? In Spain the lack of solar generation, was Supply thanks to wind energy with 31.3% of the electrical production. In addition, after what It has happened in March with heavy rainsfrom the Spanish Electric Red They announced that they had prepared to analyze and anticipate the possible effects of the solar eclipse, guaranteeing the security of the supply and the correct operation of the system.

The mental contrast -based system that is close to achievements anticipating errors

by

The motivation to achieve objectives is a crucial element to achieve them. The lack of solid arguments that justify maintaining constancy to acquire a new habitto move forward a personal project or achieve professional objectives contributes to that initial thrust to dilute over time and end abandoning your goals. The woop method is a positive thinking technique By mental contrast that puts the dreams, objectives and desires of people on the table, and confronts them to the difficulties that will be on the way. That allows differentiating the “cravings” of consolidated objectives and desires, helping you to prioritize those objectives that really improve your life and are in your hand to achieve. In short, it is a strategy that allows those who put it into great dream, while providing it with The necessary tools to overcome the inevitable challenges that will be in the process. What is the woop method The woop method is the acronym for words in English for desire (wish), result (outcome), obstacle (hindered) and planning (plan). It is a planning strategy that combines the visualization of positive results (desires and objectives to achieve) with the identification and planning of the obstacles that will appear on the way until they reach those goals. Unlike other approaches, which focus solely on optimism (pursue your dreams and come true because you are worth it), Woop gives a realistic and strategic vision to achieve them being aware of the steps that must be taken and that will not be a path of roses. This methodology is based on the “mental contrast with implementation intentions” (MCII) defined In a study by Gabriele Oettingen, Professor of Psychology at the University of New York State and the University of Hamburg, and author of the book “Rehinking Positive Thinking“. Oettingen has more than 20 years studying Human motivation and has detected great shortcomings in positive thinking. In Your studiesOettingen has discovered that positive thinking alone is not enough to achieve the objectives. Dreaming is finebut it is the obstacles of the way that make us grow and improve our skills to achieve the sets set. How to apply the woop method The first step, Desire (wish)it implies identifying a specific, challenging but realistic desire. At this point we must not be influenced by the expectations of others, but by what you really want to achieve, no matter if a personal or professional desire: to obtain an ascent, do more sports, work less hours, or eat healthier. The second step is Result (outcome). Here it is visualized what that desire would be to achieve. It would be necessary to imagine that the objective has been achieved and it is convenient to identify what positive feelings and the benefits would get to achieve it. Allow yourself to dream and experience that feeling of achievement. This second point continues to remain within the positive thought zone, but it already allows differentiating from what is a “whim” from what are real objectives and, therefore, to which priority must be given. The third step refers to Obstacle (hindered). Here We begin the questioning of dreams and contact with reality. To carry it out, honesty and self-reflection is required. What internal obstacles exist (fears, doubts or bad habits), and prevent you from achieving your desire? Identify those obstacles in the most specific way possible. A 1977 study From the American Psychological Association revealed that becoming aware of them, you are already marking a path to solve them and continue advancing, or on the contrary, it makes you take a more expand vision of your options to achieve it. In addition, by identifying these obstacles, the perspective of the obstacle is changed. For example, if your goal is to eat healthier, identify industrial pastries as an obstacle, it allows you to see it from another perspective: it is no longer so much sacrifice to give up this short -term whim, because the long -term objective is another and has priority. Finally, Planning (Plan)It consists of creating a “si-then” plan to overcome those obstacles. For example, if your goal is reduce sugar consumptionan approach for this point could be: “If you invite me to a party and there is a cake, I sign up for the party and socializo. I take coffee, I share time with friends, but I will not try the cake. If someone asks me, I can explain my goal openly.” In short, it is about drawing a contingency plan to the possible obstacles of the previous point, so that they cease to be a problem.

Figure creates a system to make large -scale humanoid robots. And of course, there will be robots manufacturing robots

by

We had something forgotten to robots, but for A few months We don’t stop to return to hear about them. There are important efforts from companies such as Nvidia – who just put All meat on the grill-, Boston Dynamics or Teslabut there is another company that is pushing strong in this sector. It is called Figure, and has just announced a promising project. Botq. This is the name of the mass manufacturing platform of humanoid robots Announced by Figure. The idea is simple: to create a totally oriented infrastructure to that production of high volumes of robots that end up being used in all types of scenarios. 12,000 humanoid robots per year. The first generation of Botq will be able to produce 12,000 humanoid robots a year, but the company highlights that this is only the beginning “and we will climb considerably from there.” Manufacture with vertical integration. The company will control the construction process and its quality to ensure that the robots that end in the market have according to them the highest quality. They have also been working on software solutions for months to attend these high volume manufacturing processes. Robots building robots. The Humanoid Robots of Figure They already caught our attention last summer, and now these robots will participate in the manufacture of other humanoid robots. That, they say, will happen this year, but in addition “the number of humanoid robots involved (in manufacturing) will grow substantially over time to increase the automation of production lines.” By the way: Elon Musk has an identical idea. Figure 03 on the way. Its current humanoid robot was complex both in necessary elements and in manufacturing processes, but with it they have learned how they can reduce the number of components and how to improve production. And more efficient processes. Thus, instead of CNC machines they will use techniques such as injection molding or pressure foundry that allow “thousands of hours of manufacturing.” In fact, in some components that needed a week to be manufactured with CNC machines, times have gone from only 20 seconds.

More than a decade ago, Seville created a system to defend against Guadalquivir waiting for not having to use it. Last night he had to activate it

by

Anyone who was yesterday at the entrance to the Pava Charco, could see how the city’s firefighters They moved the huge gates of defense that shield the city of Seville of the floods of the Guadalquivir River. And it is likely not to know, but I was attending a historical moment: it is the first time since it was built that these steel plates (more than four of meters high and five tons of weight) have to close. Phase 1. Yesterday afternoon, the Hispanic City Council activated the emergency plan in phase 1 and brought together all emergency services (including Local Police, Civil Protection, National Police and 112) to coordinate the necessary measures. 30 people were evicted from a “chabolist settlement” that was in flood zone, control points were installed and It was decided to close The connection that connects La Vega de Triana with the city. That’s where the doors that have just closed are. He has also put the neighbors of Tablada, Valdezorras and El Gordillo on alert. But hadn’t it stopped raining? Yes, weather forecasts They do not show abundant rains In the area and in fact (although the red alert is maintained) the river flow has already begun to decrease in Córdoba. However, when we talk about Seville, the river is just one of the things to take into account. The tide. Although it is often difficult to imagine, the truth is that when the Guadalquivir arrives in Alcalá del Río (that is, 15 kilometers before reaching the municipality of the city of Seville) It is already at sea level. That makes that point more or less, the entire riverbed is subjected to the influence of the tides. And that is what worries the authorities: if the river flood coincides with the pleamar, the chances that the Guadalquivir will overflow begin to be huge. How historical is this really? Indeed, to say that the doors have closed for the first time is not saying too much: they settled in 2012 and the last time the city was on the edge of the debacle It was in 1996. However, the challenge is more than considerable. Because, like Díaz del Olmo explained years agoProfessor of Geography of the University of Seville, the reduction of the alluvial plain of the Guadalquivir (which has gone from 4 kilometers to 500 meters) adds risks to the situation. “It is worth that with the swamps that retain the water, so much alluvial plain is needed, but the current one is not much less sufficient,” he said. And not only for the plain itself, but because “If the river is wide and with meanders, the energy that the water carries is blurred; but if it is narrow and straight, the water acquires a great speed … like the flow of the river rises of the 4,000 cubic meters per second … we have a problem for which they do not serve neither the storm tanks or anything.” A monster called Guadalquivir. Luckily, we are not yet in that situation. However, this is a warning for navigators: taught by tons of concrete, rivers are sleeping monsters, but monsters after all. Just yesterday we talked about The great paradox of our time: Have to prepare for long periods of drought while we have to have infrastructure to contain torrential rains. Today we see that it is not something punctual, it is the true “new normality.” Image | Toni Pomar | ECMWF In Xataka | With the reservoirs to be overflowed with the rains of March, there is a reason for hope on the horizon: the light of the light

While Andalusia and Extremadura fight against floods, the water system prepares for the next drought

by

The rains of the last days They have put end to the pertinaz drought that still affected some Spanish basins. However, water so longed for in some areas has also flooded some areas of the country, especially in the south and west of the peninsula. Flooded areas. Numerous areas of the country have dawned under the threat of floods. The rainfall associated with Borrasca Laurence has made Cut roads and evict homes Faced with the risk of floods In Andalusia and Estremadura. Part of Murcia is now under orange warning decreed by the State Meteorology Agency (Aemet). It rains a lot. A determining factor in which we have reached this situation has been the persistence of these rains. Not only has it rained much, The three successive fronts that Laurence has brought the peninsula have put pressure on the water systems of the southwest, forcing water at various points. As if this were not enough, on the Atlantic Horizon A new storm appears: Martinho. This new storm is expected to reach the Peninsula tomorrow Wednesday. Not just rain. The risk of floods has also been exacerbated by spring thaw. In this sense, Aemet has also issued Several notices yellow by thaw in areas of the central system. To what extent the situation is “normal”. We are in spring, rainfall is not something anomalous on these dates, but Aemet’s forecasts For the remainder of the month of March they are clear: the next few days are also expected wetter than usual in much of the country (except for the Cantabrian mountain range and the island communities), and especially in the southwest quadrant. End of drought? We were therefore before the end of an important drought that affected practically the entire country between 2023 and 2024. A drought that still kept some basins such as the Catalans or those of the south, despite the intense rain episodes seen in the second half of 2024. Now, we see that the reservoirs have been maintained almost constantly with filling levels above average of the last 10 years during what we have been in 2025, and this month of rainfall seems aimed at accentuating this increase (compensating A drier February than usual). Everything seems to indicate that the drought situation has been reversed. The problem is now to prepare for the next. A paradox. This leads us to a paradoxical situation and is duty Plan a drought While we disembark water to avoid risks derived from the intense rainfall we are seeing these days (and that we will continue to see during the coming ones). On the one hand, because the increase in oceanic and atmospheric temperatures facilitate the accumulation of water in the atmosphere. More loaded clouds involve an increase in the risk of intense rainfall and with it the risk of flooding. On the other hand, the drought that we live seems to be more than one of the consequences of A aridification process which affects many areas of Spain. This process implies a trend that will make the most recurring droughts.

Goal has taken the first step to dismantle its external verification system. And he has done it with an X algorithm

by

Shortly before Donald Trump returned to the White House, Mark Zuckerberg announced What a goal would end his Third Party Data Verification Program And I would bet on a system of community notes in the purest X style, the social network of Elon Musk, one of the leading allies of the new president. With this decision, goal sought Leave in the hands of users The task of pointing out and contextualizing misinformation on Facebook, Instagram and Threads. When Zuckerberg made the announcement, it was clear that, although the company pointed out with this new approach, its implementation would gradually begin in the United States. There were no indications of a possible deployment in the European Union, where the Digital Services Law could mean an obstacle. Now, with more details about the initial launch, we can get a better idea of ​​its operation. Fixed goal in the calendar the beginning of its new initiative. The social networks giant He said that It will begin to test the community notes on March 18. That is, in less than a week, this new approach will take its first steps. As planned, the deployment will be gradual and will be limited, for now, to the United States. From that day, the program taxpayers will begin to leave their collaborations. How will the system work? The community notes system in Meta allows users to add context to publications that can be misleading or need additional information. However, not any note is published immediately: there is an evaluation process that, as explained by Meta, seeks to ensure that contributions are useful and reflect different perspectives. A collaborator detects a publication on Facebook, Instagram or Threads that needs context. For example, a viral post says: “Bats are completely blind and depend only on sounding to move.” The collaborator writes an explanatory note. It must have a maximum of 500 characters and include a link to a reliable source. Example: “It is a common myth. Bats are not blind; They have good vision and combine ecolocation, hearing and smell to adapt to different environments. More info here: (Link). “ Other collaborators check the note and vote if it is useful. It is not published automatically. You must have the support of people with different perspectives, not just with a majority. If the note receives enough support, it is published. It appears next to the original publication to give context. The publication about bats is still visible, but with the explanatory note. Goal will use the X algorithm. The company led by Mark Zuckerberg has chosen to use, in a first stage, the algorithm of the notes of the community of X. This system, which promotes a similar function in the social network previously known as Twitter, is open source and It is available in githubwhich allows anyone to audit and reuse it. However, the adoption of the X algorithm by goal is not a definitive step. The company plans to take it as a basis for developing its own version. “As our own version develops, we may explore different or tight algorithms to support the way in which the community notes are classified and described.” No scope penalty. Goal ensures that its new system against misinformation will not punish the distribution of publications. Unlike the old fact verifiers program, where the marked contents could lose visibility, the community notes will only add context without affecting who can see them or how far they can go. But the notes will not appear yet. As we have said, the community notes system will begin to take its first steps on Facebook, Instagram and Threads this month, but users will not see them yet. It is an evaluation phase. The idea is that the deployment occurs has taken the first step to dismantle its external verification system. And he has done it with the X algorithm when the company is sure it works as a wait. During this period, they plan to make more adjustments and improve the system. Old system verification labels will continue to appear in the United States until the new system begins to deploy generalized in that country. And what will happen in Spain? Although the Meta External Verification Program began in 2016, did not land in Spain until 2019. In the country, the multinational continues to have verifiers such as Newtral, Maldita.es and AFP, which continue with their usual work. Meta ensures that its intention is to expand community notes globally, but it remains to be seen how possible challenges related to European legislation.

Let’s explain What are the express fines of the DGTa new system of notification of traffic sanctions. The idea is that when you put a fine you do not have to wait several weeks or even more than a month to get to you, but do it in about 48 hours. We are going to start the article explaining what this system of express fines is and what can you expect from it. Then we are going to tell you the steps to register on the web in which they are going to start applying when they are enabled .. What are the express fines of the DGT The express fines are A new notification system to communicate the fines almost immediately. They will do it through the Road Electronic Address (DEV)an official website that has been working for a while. The road electronic address is a service in which You can easily registerand with which the notifications of the DGT They arrive by email or SMS instead of ordinary mail. This allows the delivery deadlines to be expedited. What they are going to do is integrate fines notifications into the DEV. In this way, you will receive the sanctions in your email within a maximum period of 48 hours. This is something with which, according to the DGT, the pedagogical character of the fines is reinforced, because you will remember perfectly when you went through that point. How the express fines work To receive the express fines you must enter the website of the Electronic Road Address, whose address is headquarters.dgt.gob.es/es/multas/direccion-electronica-vial. Once inside, click on the option of High, modification and low in DEVwhich is in the section Access to service.

If today we can see a planetary alignment it is because the entire orbit solar system in the same plane. And not by chance

by

Tonight we will have a chance to see one of the astronomical events of the year, The great planetary alignment: Seven planets (all the major planets of our solar system) will be visible in the night sky. To understand why this phenomenon and discover what it is and what is not, it is convenient to keep in mind some details about the dynamics of our solar system and its history. That is, the very story of the planets that accompany ours in the orbit around the sun. Ecliptic. The name of the phenomenon itself, Planetary alignmentindicates that it is an event in which the planets are arranged in a row. However, we must bear in mind that when we talk about this we do not talk about the planets forming a precise row in their orbital displacements as in textbooks, nothing is further from reality. The alignment of the planets refers to the fact that, at some point, these appear aligned in the night sky, that is, it is an apparent alignment from our terrestrial point of view that occurs around an imaginary line that crosses the night sky. This imaginary line is the ecliptic, but in reality it is much more than a line marked by the planets. And it is that most of the objects of our solar system move through it. Even the stars seem to move following the path that this brand. From the album to the planets. Strictly, the ecliptic It is defined as the imaginary plane that contains the orbit of the earth around the Sun. That is why this imaginary line is marked by the movement of our star in a daily transit by the celestial vault. However, due to the fact that the orbits of planets, satellites and asteroids of our solar system orbit in different planes, the ecliptic and its surroundings become the projection in the vault of the sky of an album, the disk formed by all this infinity of orbits of objects that rotate at different distances already varied speeds but practically always in similar planes. It is no accident that almost all the subject of our solar system is presented on this album. To understand the reason, we have to go behind in time, to the formation of our solar system, to the era in which around our star there were no planets, but a Protoplanetary disc. Return to the origins. The origin of the solar system is in a cloud of gas and matter that ended up concentrating. In doing so, Due to the conservation of angular momentumthe cloud was taking one more disk appearance, turning at the same time on itself. The center of that cloud continued to concentrate, until it reached critical mass and density for the formation of a star, the sun. The rest of the album was orbiting around the sun, now like a ringthe so -called protoplanetary disk. The dust also began to concentrate on different points of this album also due to gravity. Progressive clashes were giving rise to increasingly large concentrations, dust that became increasingly large rocks until planets and asteroids were formed, all still turning in the same direction in which millions of years ago revolved the protoplanetary disc and, before, the original cloud. The movement of the Earth. There is another factor that contributes to all objects from heaven to seem to scroll in unison and it is the fact that the Earth’s rotation axis is aligned with the axis of rotation of its orbital movement. This is more or less common, although there are exceptions such as Uranus. If we were on this planet, we would see night after night that the stars distant to us move from this to west normally, but the solar ecliptic would move very differently, a more exaggerated version of the solar movement given in the polar circles, with a seasonal cycle of days and nights. This implies that in summer, the ecliptic plane would be a circle in the celestial vault, something very different from what we perceive from Earth.

‘Anora’ is the big favorite to take the Oscar for the best film. The problem is that it has the voting system against

by

‘Anora’ starts in the pools as a great favorite to take the main Oscar of the night, the best film. However, The Oscars They are much more than a mere vote that chooses the film of the year: they come into play not only the millionaire advertising campaigns that are talked about so much (which also), but models of mathematical probability and the same voting system, which do not always favor the favorite of the simple majority of academics. The pretty girl. ‘Anora‘It is Sean Baker’s film, an old acquaintance of fans of the independent cinema zone. Some of its previous proposals, such as ‘The Florida Project’ and ‘Red Rocket’they raised praise among the specialized press, but with this story of a young Brooklyn prostitute who lives his own history Cinderella when he knows and marries the son of a Russian oligarch who intends to end romance, has revolutionized the awards season. The film won the gold palm in Cannes and Dos Bafta, was nominated for five Gold balloons And now she is nominated for six Oscar, including best film, director, actress and original script. ‘Anora’, the independent tradition. ‘Anora ‘continues Oscar’s tradition to reward small and modest movies, looking for a quality patina indie that Hollywood industry is excited since the time of The infamous Miramaxand that has made films like ‘in recent yearsAll at once everywhere‘(2022),’Coda‘(2021),’Nomadland‘(2020) or’Parasites‘(2019). The winner of 2018, ‘Green Book’, was only indie in aesthetic terms, but still, is a streak of victories outside the industry that only broke ‘Oppenheimer‘ last year. The numbers speak. In addition to the recent trend of the Oscars, dyed of a certain condescension, to reward independent films, we have the purest mathematics: The Hollywood Reporter used the probability laws To make the calculation and ‘Anora’ was well above its competitors: 52% possibilities, overwhelming the second in the list, ‘Conclave‘, which was left with 15.2%. The reason? The ‘Anora’ awards streak in the Critics Choice, Producers Guild and director’s Guild. Less colorful than the Golden Globes, but according to statistics, infallible when opening via for the Oscar (let’s not forget that on many occasions the voters coincide). Percentages against competitors. These statistics in favor of ‘Anora’ are increased when those same numbers play against their competitors. For example, only seven films have won an Oscar for the best film without having the direction nomination, as happens to ‘Conclave’. ‘The Brutalist‘It is one of the favorites, but never a movie without the SAG prize or An Eddie (The US editors awards) has won the main Oscar. ‘Emilia Pérez’ had everything in favor with the Golden Globes, but Reality has passed over. Already ‘A Complete Unknown‘It has not gone wrong with other awards, but in any other gala the best film has been taken, something that greatly reduces its possibilities. But if everything is in his favor … Ya: Why are the real probabilities of ‘anara’ are smaller than, for example, those of ‘conclave’? The voting system for best film is called “Preferred System”, and with it the voters are asked to classify the nominated films from the greatest to less preference. If a film gets more than 50% of the votes (something very unlikely), automatically wins the prize. But if not, the following process is carried out: the film with less votes redistributes its ballots among the second most voted film of the members who had placed it in number one. It is done with all, until a film exceeds 50%. The terrible consensus. The idea with this system is to reward the favorite film by consensus, one that most of the members of the academy would consider their favorite. The result is that the films that go to the extremes are less likely: ‘Anara’ will be the favorite of many, but because of their theme and indies modes, it will also be among the least favorite of many others. This system rewards, in effect, the consensus, which is another way of saying that it rewards the middle ground. In that sense, it is ‘conclave’ that will benefit: a very little annoying movie, which many will have liked, but few have liked very little. The danger of controversy. Something similar to ‘Anora’ will happen to films such as ‘Emilia Pérez’, one of the favorites before the successive bombings of Karla Sofía Gascón. EITHER ‘WICKED‘, which belongs to a genre with as many defenders as detractors. Or, of course, ‘Dune 2‘ either ‘The substance‘, which only to belong to the categories of horror and science fiction will receive very low scores of the less daring faction of academics. In that sense, and except for exceptions (it is clear that ‘anora’ has possibilities, despite everything) the Oscars almost always reward the low risk. Nothing new under the sun.

There is a spiral structure surrounding the solar system

by

Thousands of kilometers from our planet there are all kinds of mysteries to discover. Some we end up deciphering them, like that Strange television signal It takes years to solve, but others remain with that halo of singularity. In this group there is everything from Low intensity magnetarsuntil those radio bursts that we detect from time to time. And then there is Oort’s cloud, a fascinating region that has just revealed something surprising. A spiral in the confines. The edge of the solar system has long been a little explored, obvious border, since it is a vast and enigmatic territory full of ice cream that orbit at extreme distances. Over there, Oort’s clouda region that extends up to 100,000 astronomical units (UA) of the Sun, has been considered a simple sphere of debris Cosmic, but a recent computational study has placed it on the front page. The reason? An unexpected and fascinating structure has been revealed: A spiral structure similar to that of a miniature galaxy. The finding, directed by astronomer David Nesvorný of the Southwest Research Institute and Posted in The Astrophysical Journal After its diffusion on the ARXIV predimussion server, it reveals that the gravitational force of the Milky Way has shaped the internal Oort cloud in a spiral structure of 15,000 A diameter. This spiral, which has endured since the beginning of the solar system, Challenge the previous conceptions about the morphology of Oort’s own cloud and could redefine our understanding of the evolution of transneptunian objects. The composition of the Oort cloud. As far as we know, Oort’s cloud has traditionally divided into two regions. The external Oort cloud, located beyond 10,000 UA, is a spheroid of icy bodies that are weakly linked to the sun and suffers frequent gravitational disturbances of nearby stars. From this region come most of the long period comets, those who travel through the solar system in elliptical trajectories after being diverted by gravitational interactions. On the other hand, the internal Oort cloud is between 1,000 and 10,000 UA, and so far it was believed that it had a more stable and disk -shaped structure. Due to its proximity to the sun, the objects in this area They are more strongly linked to their gravity and are less susceptible to external star disturbances. However, the new computational models have revealed that their shape is not a uniform disc, but a spiral structure with twisted arms and an inclined disk about 30 degrees with respect to the ecliptic plane. The influence of the Milky Way. Apparently, the key to this unexpected morphology lies in the interaction of the internal Oort cloud with The so -called “galactic tide”a gravitational phenomenon generated by the Milky Way. This force, exerted by the gravitational attraction of the galactic center, nearby stars and possible black holes, especially affects the most distant regions of the solar system. He Model developed by Nesvorný And his team was prosecuted in NASA’s Pleiades Superordinateusing data on the formation of the solar system 4.6 billion years ago. During the simulation, the scientists introduced the gravitational influence of the Sun, the impact of galactic tide and interaction with the Milky Way. Results? It was found that The spiral was formed in the first hundred years after the creation of the Solar System and has remained stable since then, even resisting the nearby step of stars in the last millennia. Implications and challenges of finding. As the researchers say, one of the most surprising aspects of the study is that the spiral is not a temporary effect or a recent disturbance, but a permanent structure within the internal Oort cloud. Comparison with previous research suggests that this form has been present in multiple previous simulations, although it had not been identified so far. However, and this is underlined at work, confirming this structure through direct observations is little less than a monumental challenge. Reasons? The enormous distance and low luminosity of objects Oort’s cloud causes even the most advanced telescopes to be unable to detect them directly. In fact, most of the evidence of the Oort cloud comes from the study of long period comets, which limits the possibilities of characterizing its internal structure with precision. And despite these difficulties, scientists consider that this finding is A crucial step to understand the history of the Solar System. The spiral structure of the internal Oort cloud could provide clues about how the icy bodies in the confines of the solar system were formed and evolved, in addition to helping to understand the impact of the Milky Way in our cosmic neighborhood. A new horizon in exploration. No doubt, the discovery of this spiral structure in the internal Oort cloud challenges the traditional conception of the already enigmatic edge of the solar system, showing that The severity of the Milky Way has played a crucial role in its formation and evolution. The finding also reinforces the need to develop new methods of observation and space missions dedicated to exploring the regions farthest from the solar system. If you want also, it enhances the idea we already had, that Oort’s cloud is still an unexplored bordera cosmic file that retains the primitive history of the Solar System. As the researchers indicate, their study could reveal key information on the origin of comets, the dynamics of transneptunian bodies and the interaction of our planetary system with their galactic environment. Next to nothing. Image | DOLANH, NASA /ESA AND A. FEILD /SPACE TERESCOPE SCIENCE INSTITUTE In Xataka | For five years we have tried to decipher a television signal that came from the sky.
