With the James Webb we have seen the oldest black hole in the universe. But you just have more questions

by

He James Webb Space Telescope has accustomed us to discoveries that break with our schemes mental The last discovery Where he has been the protagonist, he has undoubtedly re -rethink what we knew about the universe, by confirming the existence of the black hole more distant ever observed. Something that will allow answering some questions that astronomy still had. A colossus that has already been baptized. This black hole has received the name of Capers-lrd-Z9 And it is 13,300 million light years away, which means that we are seeing it as it was just 500 million years after big Bang. In this way, its existence, and especially the size it has, challenges everything we thought about how these giants grow. How this black hole was found. Finding something that is so far is not a simple task precisely. Astronomers used program data Capers (Candels-Aea Prism Epoch of Reion Survey) of the James Webb space telescope, specially designed for explore the confines of the universe. The leader of the research team, Anthony Taylor, Explain that “when looking for black holes, this is the farthest that can be reached in practice. We are really expanding the limits of what current technology can detect.” A discovery to confirm. The key to confirmation was spectroscopy, the technique that breaks down the light of an objective in its different wavelengths, such as a prism. For Identify an active black holescientists are looking for an unmistakable firm: gas that moves at extreme speeds. Turning the spiral towards the black hole, the light of the gas that moves away from us will tend towards a red wavelength, and that of the gas approaching is compressed towards the blue length. In this way, if these two trends are found, it is quite unmistakable that a black hole is ‘seeing’. In this way, the Nirspec Spectrograph The Webb detected a remarkably wide hydrogen emission line, the irrefutable test that a massive object was stirring the gas around it at speeds of up to 3,500 km/s. It belonged to something bigger. Initially, Capers-LRD-Z9 was just an intriguing motorcycle in webb images. However, it was belonging to a new and enigmatic class of objects called ‘Small red points’ (Little Red Dots or LRDS). These galaxiespresent only in the first 1.5 billion years of the universe, they are extremely compact, bright and as its name indicates very red. His discovery was “a big surprise,” according to Steven Finkelstein, co -author of the study. “They didn’t look anything like galaxies seen with Hubble.” In this way, this finding has helped explain two of the great mysteries above the table. Why are they so bright? Its brightness would suggest an unlikely number of stars for such an early era of the universe. In this way, this study confirms the theory that light comes from a supermassive black hole that is active and literally devours the subject. Something that results in hot and shines with a huge intensity. Why are they so red? The model that best suits the observations of Capers-LRD-Z9 suggests that the black hole is wrapped in a dense and neutral gas environment. This gas cloud absorbs the blue light and lets the red pass, staining the entire galaxy. Something that could be confirmed when comparing this object with other similar sources of energy. An impossible giant. The most shocking of Capers-LRD-Z9 is the size of its black hole. It is estimated that it could have a mass of up to 300 million times that of our sun. To put it in perspective, it is so massive that it could represent more than 4.5% of the total mass of all the stars of its host galaxy, a proportion much greater than the 0.1% we see in the nearby galaxies. How could it grow so much and so fast? This is one of the big questions that anyone can ask, taking into account that this black hole appeared at a very early stage of the universe. Something that questions the current models that we have on the table. Finkelstein summarizes it as follows: “This adds to the growing evidence that primitive black holes grew much faster than we thought were possible. Or they began being much more massive than our models predict.” Two models to explain its existence. The first of these is that the black hole was not born from a star, but from the direct collapse of a cloud of primary gas, starting its life with a mass of thousands of soles and growing at a normal pace. The second theory that scientists have on the table is that it was actually born from one of the first massive stars (with a mass 100 times higher than the sun) that existed. The question here is that he would have grown at a rhythm ‘Super-Edington‘, devouring matter much faster than the stable theoretical limit is considered. There is still much to find out. The team expects to obtain more observations with the Webb to unravel the secrets of this single object. “We had not been able to study the early evolution of black holes until recently,” concludes Taylor, “and we are excited to see what we can learn.” Images | Nasa Hubble Space Telescope In Xataka | Two astronomers studied the “sound of the Big Bang” and reached a disturbing conclusion: the earth is in a lonely bubble

The James Webb has just photographed one of the great mysteries of the universe’s galaxies: how they intertwine

by

How many galaxies fit in an image? In the instruments of the James Webb space telescope (JWST), at least, many: hundreds. And even thousands. From close to the distant. The image taken by the JWST (with the help of the veteran hubble) and published by the European Space Agency (ESA) It shows us objects in a wide range of distances: from stars located within our own galaxy (easy to distinguish thanks to The characteristics six points of diffraction of this telescope) to distant galaxies in space and in time. The “star” of the image. However, according to Explain the agency itselfthe main protagonist of this capture is none other than a cluster of galaxies that we can see below the center of the image, a distant group of galaxies that shines in a mixture tone of white and gold. This group emerged about 6.5 billion years after the Big Bang, when the universe as and as we know it was somewhat less than the age it is now. The importance of this group lies in the fact that more than half of the galaxies we know can be found in similar groups, so studying it can help us understand more about how these groups that make up the greatest structures linked through the force of gravity are formed, says ESA. Cosmos-Web. The outstanding group is the largest galactic cluster in the region called Cosmos-Web Field. COSMOS (Cosmic Evolution Survey) It is a survey that uses telescopes such as webb, hubble or the XMM-Newton Space Observatory of ESA to explore the spaces and space phenomena that occurred in that celestial region. He Cosmos-Web program It seeks to take advantage of the high abilities of the JWST and instruments such as the Nircam filters on board to explore and map an area of ​​0.54 square degrees of the celestial vault, a little more than twice and a half times the area that occupies the full moon in our sky. This power of the instruments of the orbital telescope should allow us to understand how galactic clusters formed, taking us at a time when the universe was only 1.9 billion years old, 14% of their current age. This is intended to meet three objectives: identify galaxies at the time of reion (when the first stars were “caught”; probe the formation of the most massive galaxies; and understand the relationship between the mass of the stars in a galaxy and The galactic halo that “wraps.” “Galaxies feast ”. In its publication, ESA has given some additional details about the image we see. They explain, this combines nircam images (Near-Infrared Camera) with Hubble observations to present ourselves “a visual feast of galaxies.” In capture They can be seen galaxies of different types and even pairs of galaxies in the process of merging. The European Agency He also explains The interpretation of the colors of the galaxies: the galaxies that tend to the bluish tones are those in which young stars predominate, while the most old are older; either because of the color of the stars inside, either because they are further in space and therefore in time. The latter is the effect of the phenomenon called Redshift or red shift. Galactic evolution. Images like this have to tell us about the evolution of the universe and, above all, of galaxies like ours. The gravitational interaction between galaxies (more or less) close affects what happens within the same galaxies, such is the mass that these groups accumulate. And not only that: collisions and mergers between galaxies in the same group also condition what happens in these. An example can find it when the nearby step of two galaxies of different size allows a huge clouds of matter “start”, or it can Cause a “burst” that quickly consumes the gas of this.

The largest map of the universe is now available thanks to James Webb. And it can be explored as if it were Google Maps

by

Astronomers They were convinced that the primitive universe was a dark place. That the galaxies took to appear after the Big Bang. But the new largest and most deep map of the universe, which extends until 13.5 billion years ago thanks to the observations of the James Webb space telescope, has just dynamited this idea. You can explore it yourself. Is called Cosmos-Weband it is not just a mosaic of images. It is a detailed catalog of almost 800,000 galaxies that covers 98% of the entire history of the universe in a specific region of heaven, thanks to the extraordinary sensitivity of the Webb Observatory. This gigantic panoramic is the result of More than 255 hours of observations of the NASA space telescope, ESA and the CSA, pointing to a region with very few stars or clouds of gas that block their vision towards the confines of the cosmos. The result is the largest contiguous image captured by the Webb to date, with more than 10,000 individual exhibitions. Comparisons are hateful. One way to understand the scale of this map is comparing it to the famous “Ultra -Profundo del Hubble”, the most detailed image of the universe in visible light. If we had a printed copy of the hubble ultraprophound field on a sheet of paper, Cosmos-Web would be a mural of almost 4 by 4 meters with the same depth. The Webb telescope observes wavelengths other than those of the Hubble, those of the nearby infrared and the middle infrared, but its instruments are so sensitive that you can see those 800,000 galaxies over 13.5 billion years in a region equivalent to three moons full in the night sky. Too much light, too soon. The great surprise of these images is not their depth, something for which the webb was designedbut what they reveal from the primitive universe. Astronomers believed that there would barely galaxies in the first 500 million years of the universe were incredibly rare, but there are approximately 10 times more galaxies than expected. “Since the James Webb space telescope went on, we have been wondering if your data They break the cosmological model“, admits Caitlin Casey, leader of the Cosmos-Web project.” The primitive universe only had about 400 million years to form one billion solar masses in stars. We just don’t know how it could happen. “ The role of Spain and open science. This monumental effort would not have been possible without a globa collaboration. And this is where Spain plays a role from the Institute of Astrophysics of the Canary Islands (IAC), which applied neural networks for the morphological classification of more than half a million catalog galaxies, an essential task to understand its evolution. But Cosmos-Web would not have been possible without the work of volunteers who, from their homes, helped for two years to process the raw data and correct artifacts of the Webb Telescope. Similarly, now anyone can explore the map and make their own discoveries. Cosmos-Web will continue to expand with new spectroscopic observations to analyze the internal chemistry of the most interesting galaxies. The main objectives are the “era of reion” (when the light of the first stars cleared the cosmic fog), the evolution of mass galaxies and how dark matter is related to visible matter.

In 1995, a reading club began reading James Joyce’s most difficult book. 28 years later it is finally finished

by

More than a quarter of a century has taken Gerry Fialka, a Californian experimental filmmaker, in bringing a very ambitious purpose: a reading club of ‘Finnegans Wake‘, James Joyce’s book that is famous not only for his extraordinary literary quality, but for the difficulty involved in his pages. Literary nightmare. ‘Finnegans Wake ‘was published by deliveries from 1924, and was only edited as a book fifteen years later, when its title was also revealed. Since its first edition, the hostility of critics and readers was won by Your difficultywhich sometimes seems to be written in An invented language (in fact, mix words of seventy languages), and with which Joyce seeks to reproduce the way in which memories are ordered and reproducedwith words of multiple meanings and that try to challenge literary conventions at all times. 28 years. From this monumental fuck (‘Finnegans Wake’ is the closest that literature has been to generate a completely new means of expression), Fialka congregated every month in a local library to a group of between ten and thirty people. Your mission: comment in each session two pages of the book. The purpose was so ambitious that they ended up having to reduce it to a single page a month. They began in 1995 and 28 years later, in November 2023, they managed to finish reading full ‘Finnegans Wake’. Why get into this authentic scrub? The Guardian He spoke with Fialka when the reading came to an end, and some of his usual people commented on the appeal they had found in the monumental task. Bruce Woodsis, a 74 -year -old Disney retired animator, says that although “there are 628 pages of things that look like typographic errors,” he has not stopped rereading the novel since his adolescence, and that he finds in it “something of visionary.” Woodsis allowed himself to leave the club for two decades to return to him when he found no other to analyze it so intelligently. At that time, the club had only advanced fifteen chapters. A special club … With such a special purpose and novel, it is clear that we do not talk about a club to use. Fialka himself defines him more as “a Performance Artistic that a reading club “, and also speaks of the club as” a living organism. “The group ended up finding a purpose despite a few initial months of chaos and gallimaties comparable to the sensations that the book itself awakened. The curious thing is that the interpretations of the work themselves are all valid, because Joyce died not long after publishing it: he could not explain it. … for a special book. Sam Slote, One of the greatest experts In Joyce of the world, he affirms that “we must accept that no one will understand it, and that is where the idea of ​​community reading enters.” After all, Joyce himself affirmed that “the demand I make to my reader is that I dedicate all his life to read my works.” Fialka and his people seem to follow their indications, although they are not the only ones: Slote states that there are more than fifty reading groups of ‘Finnegans Wake’ throughout the world. Other clubs. Some of them seem to be trapped in an eternal literary return: the ‘Finnegans Wake’ club of Zurich has read it three times in forty years. One of them lasted eleven. And when they end, they start again, something that the book itself helps: the last sentence is interrupted in the middle and recover on the first page. Of course, Fialka himself, who is already seventy years old, has had no choice but to start again: in November last year they began their second reading of ‘Finnegans Wake’.

The James Webb has found a galaxy when the universe was 330 million years old. Hide an entire enigma

by

The immense capacity of the James Webb space telescope (JWST) to see the confines of the observable universe also allows us to see how our universe was billions of years ago. Recall that, the finitude of the speed of light implies that what we see further in space is also further in time, which makes JWST a kind of time machine. JADES-GS-Z13-1. The James Webb has detected again the light emitted by a very distant and therefore ancient galaxy. The telescope has captured the appearance of Jades-GS-Z13-1 as was 330 million years after big Bang. So old and distant is that its observation implies a new enigma: the enormous density of the universe in that era should prevent its observation billions of years later. And light was made. The original universe was a dark place. If we go back enough, we will reach an era in which the universe was too dense for the light emanating from its particles to travel the space. The cosmos cooled as it expanded, so, when the photons had space to move around, there were no particles to issue them. The thing changed when hydrogen atoms began to join to form the first stars and galaxies when the universe I was a few million years old. In this long process it is called reionization, a byloys in which hydrogen clouds were reactivated and emitted new light. Even in this context, the universe was dense enough to part of the radiation of these first galaxies was overshadowed by a dense layer of neutral hydrogen. This is the case of Lyman-Alfa or Lyman-α. Redshift 13. The team studied the luminous spectrum of the galaxy to estimate its red shift or Redshift. The expansion of the universe means that, in the long run, the frequency of the light emitted by this galaxy is reduced, that is, the universe, when expanding stretches the electromagnetic waves as if it were a magnet. This causes the visible light to store towards the red tones and to the infrared after long trips. The level at which the light comes “stretched”, its value Redshiftallows us to estimate the distance at which the galaxy is found that the broadcast. The observations made from the JWST Nircam instrument allowed the team estimate value Redshift of 12.9 (either z= 12.9) For this galaxy, but to confirm this value, the team decided to study the complete spectrum through the Nirspec instrument (Near-Infrared Spectrgraph), also aboard the space telescope. It turned out that they were infrastiming their distance, which was closer to z= 13. Lyman-α. However, the spectrum study caused the team to detect something strange in this galaxy, at a specific point of the spectrum, the Lyman-α radiation lamade, a type of electomagnetic emission associated with hydrogen atoms. The broadcast captured by James Webb’s instruments was much more intense than it should according to current cosmological models. The details of the study have been published In an article In the magazine Nature. Two possible explanations. In his article, the team speculate with possible explanations To this anomaly. The first involves the possibility that the stars of the galaxy, which would have been some of the earliest in the universe, would have created a “ionized gas bubble” around the galaxy. This possibility would imply that the primal stars would have been “more massive, hotter and more luminous” than the stars formed in later stages of the universe. This possibility would give us new clues about the enigmatic population of stars known as Population III and that represents precisely these early stars of the universe. The second possibility implies the existence of a supermassive black hole in the center of an active galactic nucleus.

Almost 20 years ago a telescope captured a “cosmic tornado.” Now, thanks to James Webb, we know he hid a galaxy behind

by

Appearances often deceive. A unbridled eye could well confuse one of the planets in our solar neighborhood, such as Venus, with a distant star. We could also see an image taken by a telescope and think that the two objects that most attract attention on it are part of the same cosmic phenomenon. This is precisely what happens in the last image of the James Webb space telescope (JWST). A cosmic tornado. While the new image seems to show a huge nebula filled by a star on the tip; What we really see It is the combination of the emanations expelled by a nascent star, called Herbig-Haro 49/50, and a galaxy located far behind in the plane. Herbig-Haro. The calls Herbig-Haro objects They are produced by the form of a star formation, specifically they are the result of the expulsion of matter during this process, matter that can accumulate in regions several light years away from the birthplace of the star. This matter “cools” emitting light both in the visible spectrum and infrared. Herbig-Haro 49/50 (HH 49/50) It is one of these objects. The appellation of “cosmic tornado” received it after the Spitzer space telescope observed it in 2006. The image did not allow to distinguish with certainty what type of object we saw at the tip of this cosmic tornado. A distant galaxy. The new image of James Webb allows us to see this luminous object with great definition, showing us the small details of a distant spiral galaxy. In its bluish center are the oldest stars. In its spirals of more reddish tones the galactic dust and areas of intense star formation would be concentrated. Comparison between the image of the Spitzer Space Telescope taken in 2006, and the last Inagen captured by the James Webb. NASA, ESA, CSA, STSCI, NASA-JPL, SSC Back to the foreground. But, let’s return to Herbig-Haro 49/50, the foreground of the image. The cloud of matter we see is within our galaxy, about 625 light years from our solar system. What we see are waves of bright hydrogen molecules, carbon dioxide and dust grains loaded with energy, red and orange tints in this false color photo. This formation is found in the Chamaeleon I cloudy complex, one of the regions with the formation activity of closer stars in our galaxy. Experts estimate that this “jet” of matter moves between 100 and 300 kilometers per second. And what about the star you are emanating? Astronomers believe that it is about cederblad 110 IRS4, a protoestrella Located at 1.5 light years From this cloud and visible in the image of the JWST, below right. Cederblad 110 IRS4 is a class I protoestrel, that is, it is in a rapid accumulation phase of matter. A combined image. The new image captured by the JWST is a combination of several snapshots taken by this telescope fruit of international collaboration. To create it Observations were combined of two of the instruments of James Webb, Nircam (Near-Infrared Camera), And Miri (MID-INFRAED INSTRUMENT).

The Colombian footballer James Rodríguez already begins to bear fruit with the León Club after being in charge of giving his team the victory against FC Juárez on day 3 of the Clausura 2025 Tournament of the MX League after scoring a penalty; With this action, not only the love of the fans has been won but also the respect of several world football figures. This weekend The president of Rayo Vallecano of Spain, Martín Presa, decided to send a congratulation message to the Colombian in which he also showed that they do not forget him thanks to the great role he had within his organization when he was inside his ranks despite not his best stage in the old continent. These words were carried out by the manager during an interview offered for Dazn, where he considered that the coffee maker has very good skills that have allowed him to devote himself as one of the best South American figures in Europe; He also wished him the best of successes inside the León Club so he can continue to shine on the pitch. “We have been lucky to have a world -class player like James in light but by circumstances he has not fit our game system as we wanted. I wish you the best of luck both in León and in the World Cup and World Cup of Selections. I send him a big hug, ”he said. James proud For his part, James Rodríguez himself was quite happy and proud of having given the victory to the León Club and assured that it is a job that will continue to be able to shine within the institution and thus support them to achieve the classification to the league and later to the MX League champion title. “An important victory today, now we have to think about three days that we have the game against Chivas on Tuesday. You have to do things well too and well, the most important thing was that it won today and that helped us more, ”he said. “Well, happy, the most relevant thing is to help this team, I want to help my teammates play well and of course also to win. It is a big pride, but well, I think there is still a lot, we are on a good way and we have to continue along this same path. They want to play each super competitive game and that is what we all want, ”he concluded.

Wilson James Rodríguez, father of Colombian footballer James Rodríguez, is very excited to be able to see him inside the Club León of the MX League after his recent signing that allows him to maintain his active career in one of the most iconic Aztec football teams and with the aim of conquering the title of the Clausura 2025 tournament. During an interview offered for Mediatiempo, James’s father spoke of how valuable it is for him to see how James followed his steps within international football to become one of his country’s most iconic figures in recent years. “I congratulated him because it is a city (León) that has a lot of competitive football and the truth that makes me happy, I’m glad because he has continuity. James Rodríguez, a humble, simple person, a worker like all professionals, but very good. He is an excellent person, ”he said. “I think that in football that is born with one. When you see the children crawling, when they see starting, they begin to grow and start, that is born with one, but I did not think it was going to be such a big boy, so at the level. They are things in life, ”he added. Rodríguez Mr. coffee hobby. “The mentality. That positive mentality you have when you play with the selectionwhen he plays in the teams, that I believe that he does things professionally very well. He is a very structured person, very disciplined, ”he said. “Well, it’s a pride, a very big pride, because times are going to spend again to have one like James. James Rodríguez, my son. I also played football, but he set a difference. I think it’s impossible to match, ”he said. Finally, Wilson said he spoke with James after his debut with the León Club in the Clausura 2025 Tournament of the MX League to be able to congratulate him for the work he did; He was also concerned about the role he usually has with the Colombian team and the responsibility of taking them to the 2026 World Cup. “Very well, I congratulated him. Those are players that make a difference. The team entered and changed. He made a difference. Yes sir. It is the great hope of Colombia for the qualifiers, for the World Cup. It has always been, it has always been, and he is a good leader, a positive leader, ”he said. “It should not be easy to always load with responsibility, right? I say, he likes to play, brand difference, but he always knows that he is the obligor, because he sees the fansunderstanding that it is a collective sport, but that the fans see it. It must be complicated, ”he concluded.
