A superstructure of more than one billion light years

by

Almost a third of all the galaxies that we can observe in the universe are grouped into five structures of an unimaginable scale. Astronomers have just discovered the greatest of all. With more than one billion light years in diameter, Quipu is the largest supplies ever discovered. A super -as -called Quipu. Quipu is A galactic supercumulus of 1.3 billion light years (more than 400 megapatscs) with an estimated mass of 2 × 10¹⁷ solar masses, about 200 four times more massive than the sun. The pantagruélica structure has been baptized as quipu in honor of the strings and knots system of the Incas. The Inca wove wool threads making knots in different ways to count or transcribe messages, such as those that scientists begin to decipher in the filaments and ramifications of these cosmic superstructures. The cosmic network of matter. Our galaxy, the Milky Way, is part of the local group along with its neighbor Andromeda, the triangle galaxy and numerous satellite galaxies. The local group, in turn, is part of a large collection of clusters called the Galactic Super Cumulus of Virgo. At the same time, Virgo’s supercumulus is within a gigantic filamentous structure called Laniakea. Laniakea contains approximately 100,000 galaxies and extends over 520 million light years. Thus, as the scale increases, the matter of the universe is weaving a cosmic network that astronomers are trying to capture on a map. Five superstructures. An international astronomer team located in Germany, South Africa and Spain has made The first study at a global scale of the biggest structures of the universe. Using galaxies clusters observed in X -rays By the Classix Cluster Survey, the researchers identified five especially prominent superstructures. In addition to Quipu, they found Shaley, Serpens-Corona Borealis, Hercules and Sculptor-Pasus. These five superstructures group approximately 30% of the galaxies and 25% of the matter of the universe, occupying 13% of the total volume. Its small lateral ramifications visually evoke the knots of a quipu, which somehow encode crucial information on the formation and evolution of the cosmos. Quipu’s influence. Immense concentrations of mass such as Quipu are fundamental to understand how the network of matter is weaved in the cosmos and why there are discrepancies between the Hubble constant, which measures the expansion of the universe, and the speed at which the galaxies are separated. Quipu’s enormous mass exerts a significant impact. Its severity is so great that it can be inducing peculiar movements in the galaxies, as well as distortions in the microwave background radiation, a very weak electromagnetic echo from the Big Bang.

There is no reason why the price of light rises. There is a storm of reasons and are related to gas

by

Europe does not leave one to get into another. Why has the price of light uploaded this time? Beyond that we have returned to the VAT of 21% in the light invoice, if you have noticed an increase in the price of electricity and gas lately it is for the delicate moment that the natural gas industry lives again in Europe. The perfect storm of gas. This is how They call analysts To a confluence of factors in the gas industry that has the unfortunate European consumers suffering the consequences on the electricity bill. Regulatory measures that come to an end, a sudden reconfiguration of supply routes and the increase in demand for wind shortage have generated a scenario in which electricity prices have firing again, affecting both homes and To industries. Goodbye to the top in the price. More than two years ago that the European Union established a stop at the price of gas as an emergency measure to counteract speculation and relieve the crisis caused by the Russian invasion of Ukraine. That mechanism expired on January 31so now the reality is different. Much of Europe has started the month of February heating with gas, but without a “firewall” that slows the expense, a situation that has raised criticism of several Eurodiputados. Italy in particular asked to reconsider or adjust the threshold so that consumers do not pay excessive prices. Total interruption of Russian gas. At the same time, the energy relationship between Europe and Russia has not gone to better. The Total gas traffic interruption Through Ukraine, an agreement that since 1991 allowed Moscow to supply the continent, has left several countries in a vulnerability situation. One of the most affected countries It is Moldovawhich is not yet part of the EU block. Although the dependence on Russian gas is getting smaller, the supply maintained relative stability throughout the region. The new gas routes. Given the disappearance of the traditional route, Europe has had to resort to alternatives such as Liquefied natural gas that comes to us by ship from the United StatesCatar and Australia, or the limited use of gas pipelines such as Turkstream. These sources allow to maintain the flow of energy in exchange for a much higher cost than the gas transported by land, which translates into rates of up to 50 euros per megavatio hour and, therefore, a direct rise in the prices of the prices of the prices of the light. A WINDER WITHOUT WIND. The impact is aggravated in the electricity sector, where the demand for gas for generation has reached historical levels. The most flagrant case It happened in Germany because of the famous Dunkelflautebut the analyst Pedro Cantuel He points out that Spain registered in December 2024 the highest demand in ten years. And reservations going down. The last edge of this scenario are gas deposits. Point out Bloomberg that storage levels in key countries such as France and the Netherlands are below the objectives set by the European Commission, adding a layer of uncertainty for next winter. The Difficulty replenishing these storesaggravated by summer contracts with high prices, it is a real risk for the security of the supply that has ended up affecting, like everything else, on the electricity bill.

Putin has ordered to launch a Russian version of Eurovision. The last time the nation voted on lighting the light of the living room

by

In geopolitics, very few things are left to chance, much less if what it is about is to extol the national values. Let’s put as an example Europe and “your” Eurovisionthat strange mixture of cultural exaltation of the peoples of the continent through music, a formula Martian that continues to awaken passions and quite the opposite for decades. In fact, even Russia has signed up for the formula. It is called interview, and in reality its history is older. Relive Russian music. As we said, Vladimir Putin has ordered the return of the Musical Interview contestthe ancient Soviet response to Eurovision, After the exclusion of the nation of the European contest in 2022 Due to the invasion of Ukraine. The event, which will apparently will be held in Moscow this fall, seeks to promote cultural and humanitarian cooperation among the allied countries of Russia, with the participation of nations such as Brazil, China, India and Cuba. The origin of interview. Released in 1977 in the middle of the Cold War, Interview It developed as A platform to promote cultural unity within the communist bloc and compete with the popularity that Eurovision already had then. It was also sought to show aval after Stalin’s death. However, if the event is remembered for something, it was for an unusual event. A peculiar vote. The lack of phones in Soviet homes forced The implementation of an unprecedented voting method: The spectators had to light the light of their house if they liked a song, or remain dark if not, allowing the electric company to register the consumption peaks and determine the winner. The success of the program resulted in surreal situations, with much of the nation in the dark at times, or totally illuminated. During its four editions, The contest managed to attract non -European countries like Cuba and Mongolia (or Finland, who was the only country he can say with “pride” that he has participated in the fever Kitsch In both blocks), standing out as a propaganda event that sought to project an image of diversity within the socialist block. End to the first stage of interview. The sunset came as the Soviet Union began to weaken at the beginning of the 80s. The contest was canceled in 1981 And since 1984 it would be Polish television TVP that resumed the organization of the festival With the old name of Sopot. In 2009, Putin proposed to restart interviewthis time between Russia, China and the countries of Central Asia, mostly members of the Shanghai cooperation organization, although it did not crystallize. Eurovision and rupture with Russia. From his first participation in Eurovision in 1994, Russia became one of the most competitive nations of the contest, although achieving its only victory in 2008 with Dima Bilan. However, Kremlin’s rejection of the evolution of the festival, where messages of diversity and visibility LGBTQ+ have won prominence, led to great tensions. Conchita Wursst’s victory in 2014 marked a breakdown: while Europe celebrated its inclusion message, In Russia the reaction was outragedwith Putin and his allies condemning the “moral degeneration” of the contest. As we said, the invasion of Ukraine in 2022 sealed the definitive exclusion of Russia, which has now promoted the search for its own alternative. The “new” interview. The Guardian told this week That unlike the current Eurovision, which celebrates diversity and inclusion, this “remake” interview will adopt a conservative approach. Planning documents have revealed that Artists must respect “traditional spiritual and family values” and avoid any political content or “humiliate the honor and dignity of society.” In fact, Russian officials have affirmed that the contest will serve to promote “real music”, as opposed to what they consider “false” Western influences. International support and doubts. Apparently, Putin has discussed the initiative with Xi Jinping, receiving the support of Chinawhich suggests that the program could become an emblematic event for the geopolitical alliances of Russia. That said, doubts persist about its success, since Moscow has failed in previous initiatives to replace Western events, Like friendship gameswhich sought to rival the Olympic Games. In a world where entertainment is a weapon of mass influence, Putin’s commitment to a festival with its own seal is a declaration of intentions: Russia not only wants to challenge the West in the military and geopolitical field, but also in the cultural. That Eurovision is prepared. Image | Flowcomm, Serge Serebro In Xataka | Film rooms are becoming “show rooms” of all kinds.

They are almost 6,500 million light years

We are accustomed, or almost, to listen that the James Webb space telescope (JWST) has discovered a new galaxy in the confines of the observable universe. However, it is not always necessary to go so far to appreciate the immense power of the orbital telescope. Just stay halfway. 40 new stars. An astronomer team with representation of the University of the Basque Country and the DIPC (Donostia International Physics Center) has managed to capture in images and identify 44 new stars. This is the greatest number of stars identified in the distant universe to date. In addition to the stars, the team also discovered what could be a distant supernova. To almost 6,500 million light years. What makes this singular finding (in addition to the bulky number of stars found) is in the distance of these stars: these are found 6,500 million light yearsspecifically in the dragon arch galaxy. The stars find at such a distance that we see them as they were when the known universe had approximately half of their age. This galaxy is behind an immense cluster of galaxies, called Abell 370. A new lens for the JWST. The presence of Abell 370 It was instrumental in the discovery of these stars. All due to the gravitational lens effect. The enormous mass of these galaxies distorts the space around it, which diverts the light similar to how the lenses of a telescope do. This allows James Webb to see objects furthest than in principle would allow their already wide capacities. This phenomenon is also responsible for the “arched” aspect of the galaxy in which the newly discovered stars are located. The dragon arch is a spiral galaxy whose image comes to us as if it were a gum, all due to the influence of Abell’s cluster 370. The color of the stars. In his analysis of these stars, the team responsible for his discovery paid special attention to these. They discovered that it is red supergigants (such as the giant Betelgeuse, visible in the constellation of Orion). According to Explain the teamthis contrasts with previous similar findings that had predominantly detected blue supergigants. The details of the study were published In an article In the magazine Nature Astronomy. A new way to unravel dark matter. Beyond the relevance of finding such distant stars, the team highlights that the finding can teach us new details about the cosmos. Specifically, help us to reveal the mystery involved in dark matter.
