The collision between the Milky Way and Andromeda has begun. The good news is that it will not be necessary to fill a friendly part

We know that the gaseous extremes of our galaxy and our neighboring galaxy are being touched, but there is no worry. Although astronomers safely a fusion of the Milky Way with Andromeda, they now question it. Short. A astropathic team has just published the biggest portrait of Andromeda, our neighboring galaxy, thanks to the Hubble observations. The image covers 600 fields of vision of the space telescope and shows the entire Andromeda album, which now has more than 200 million censored stars (two orders of magnitude more than those known so far). Although Andromeda’s gas bubbles are already touching the Milky Way, the new data 50% reduce probability that galaxies collide. Gaseous collision. In 2020, the Amiga program mapped 43 quasars in the background, confirming that Andromeda’s plasma halo, a hot gas bubble that measures two million light years, It flasses with the gas halo of the Milky Way. In a way, the gaseous bodies of both galaxies are already being touched, although in a faint way that neither the stars nor the planets notice it, so it will not be necessary to fill a friendly part of an accident. Maybe it never happens. The New 2.5 Gigapixel image of AndromedaResult of the PHAT and PHASET observation campaigns of the Hubble, it is not only another feat of the space telescope. It has served to question the theory that Andromeda and the Milky Way will end up merging. The classical narrative said that both spiral galaxies They would melt in about 4.5 billion yearsforming a giant elliptical. The new model, published in Nature Astronomyreduce the probability of fusion to 50% after 100,000 simulations. How they know. Astronomers at the University of Washington integrated the new Hubble data and the Gaia space telescope of the European space agency in their simulations. In addition to Andromeda and the Milky Way, they included the updated mass of the Great Cloud of Magallanes and m33. The key is in these two satellite galaxies. M33 Andromeda and the probability of shock increases. But the great cloud of Magallanes, with an almost perpendicular orbit, pushes the Milky Way out of the plane and reduces the meeting rate. In the most extreme stage, the front blow is still possible; In the softest, both galaxies will limit themselves to orbly during eons. What we were. The contact of the Andromeda plasma halos and the Milky Way suggests that the exchange of gas between both galaxies has already begun, but that does not guarantee a galactic fusion: the discs are still 2.5 million light years. In order for the merger to occur, the friction of the hals would have to stop the galaxies until the separation is 300,000 light years. Half of the trajectories simulated by the new study discard it.

The Benidorm of North Korea is about to open. Your problem is how to fill the crazy number of rooms

In October 2024 confirmed the plan that had Pyonyang in hands. Benidorm is only one, but if tourism has become the Economic engine Of so many nations, they did not want to stay in the saga. Thus, North Korea announced that the ambitious project to turn Wonsan into a kind of Benidorm to the Korean There was a stern wind. The idea is now about to become a reality, it is called Wonsan-Kalma, and the number of rooms has gone hand in hand. An unparalleled resort. As we have gone countingKim Jong’s ambitious tourism project on the Kalma Peninsula, on the east coast of North Korea, seeks to position itself as one of the world’s greatest holiday complexes. A fact exposes the intentions: it has an estimated capacity between 7,000 and 20,000 rooms. Conceived as a tourist city from scratch, the resort Wonsan Kalma is described by analysts as the most huge tourism project ever driven by the regime. Announced Back in 2014the complex suffered multiple delays attributable to international sanctions and then at the closure of borders during the pandemic. However, its opening is already planned for June, and the regime has rehearsed a shy reopening to international tourism, although the economic viability of the resort remains deeply uncertain. Tourism as a strategy. Kim conceives the resort not only as a source of income in foreign currency, but as showcase of power and the modernity of your regime. However, the attractiveness of the enclave is in question: experts like Bruce W. Bennett and Marcus Noland They explained this week The doubts that foreign visitors attract in sufficient quantity to justify their huge investment. The logical basis of the project, which presumably aspired to capture South Korean tourists for its proximity and purchasing power, collides with the diplomatic impossibility of allowing them to enter. Meanwhile, and as We explain weeks agoRussian agencies have begun Offer tour packets for Citizens of Vladivostokbut even there the enthusiasm is doubtful. Russian travelers, According to the operators themselvesThey continue to prefer traditional destinations such as Thailand or Dubai. Oasis restricted to internal consumption. Thus, another plausible strategy of the regime would be to take advantage of the resort as an internal control and reward mechanism. They counted in Insider that the facilities could be used as an incentive for loyal citizens or exemplary workers, and the complex is designed with areas reserved for presidential delegations and suites. The problem? As Bennett points outaccess will be rigorously segregated, mainly to prevent North Korean citizens from entering foreign visitors. This structure reinforces the propaganda nature of the resort that, a priori, would serve more as a political showcase than as a real tourism center (something similar To “little manhattan” They raised recently). Structural limitations. Despite the monumental effort, the project drags many of the endemic problems of the regime. The Lack of experience North Korean in the hotel industry and the rigid state censorship are important obstacles to offer a credible tourist experience. In addition, recent history of the Ryugyong Hotel (That unfinished skyscraper for decades and symbol of North Korean failed excess) remains a latent warning. Plus: Kim’s fear of the free flow of information is incompatible with the logic of contemporary tourism. Therefore, although it is seen of modernity and luxury, it is likely to end up being Another monumental decorationwithout sufficient and useful tourists only as a propaganda tool. There is several examples similar A “diplomatic” letter. If you want, in parallel, the complex can be seen as a piece on the diplomatic board. In 2018, Trump had suggested Kim towill help your “big beaches” For economic development, and it is not ruled out that the resort is used precisely as a symbolic gesture in future negotiations, especially if Pyongyang seeks recognition as a nuclear power. Remember that the nation already has made “resort” For Russian soldiers. In that context, Kalma can always fluctuate, like promise or threat: It can be used to show openness or reinforce the cult of the leader. If so, Kim Jong Un, determined to differentiate himself from his predecessors, could see in “his Benidorm” not only a tourist destination, but a political statement to the world.

Chrome’s extensions have a big problem. Anyone can buy them and fill them with malware without finding out

One day John Tuckner decided to try to be evil. He found a browser extension called “Website Blocker” that could buy for $ 50 and took it. The extension, which allows to block certain websites so that the user is not distracted with them for some time, was especially interesting because it allowed to reuse it for spam attacks. And then things happened. Sight problem. In just a few days I had control of the extension and could do what I wanted with it. He modified the code, published the update and confirmed that the novelties had reached all users without being found. And then told what was happening: He is the founder of the cybersecurity company Secure Annex, and wanted to confirm their fears: there is great danger with extensions: anyone can buy them, modify them and reuse them for all kinds of purposes. Google reviews the modifications, but “it is not clear about what level of scrutiny,” Tuckner explained. Another recent case. At the end of January the creator of the Browser Boost Extra Tools for Chrome extension sold this development and transferred it to its new owner. Its 30,000 users were soon exposed to the new code, which dynamically redirected websites that the new owner decided unilaterally. I have not been. One of the extension users He warned of the problem in the github repository of the extension and analyzed the code notifying the danger of malware that could reach due to the new owner. The creator, n0m1111, explained who had sold the extension months ago and was no longer responsible for the code. Playing with permits. These extensions often allow permits of all types of browser parameters. Tuckner explained how in the extension he bought a permit called “declarativemetretreQuest” was used that was very wide and allowed to redirect users to false authentication sites to steal their passwords. Other permits would allow the owner of an extension to take screenshots with sensitive information or access the cookies that the browser keeps to steal data from the browser sessions. The possibilities are multiple and in Xataka we already talked a few months ago about how extensions They are becoming a silent method to infect users. A recent attack. In February, the Gitlab Threat Intelligence expert team They discovered A group of 16 Chrome extensions “used to inject code into browse to facilitate advertising and SEO fraud.” Among them they added 3.2 million users, and in Gitlab confirmed that the extensions had been bought and then modified, which allowed to avoid suspicions by users and the industry itself. These experts notified Google of the problem, and the company eliminated them all in January 2025. Block extensions, the solution. If you want to protect yourself from these problems, the solution is block The execution of extensions in your browser, especially in computers that handle sensitive data such as work. Unless they are extensions of trust, these types of problems can cause serious security problems. Care with permissions. Browser extensions can end up being bought, sold and reused without notice by their new owners, as has been the case. That raises a serious problem for users and companies, which before installing an extension should provide A lot of attention to permits that ask for these extensions to work. What do they say in Google. In Xataka we have contacted Google responsible and we will update this article if we receive new data on the subject. Be that as it may, the company offers A HELP DOCUMENT In this regard and also indicated in a Article in your official blog How to stay safe with the use of extensions in Google Chrome.

Japan had in Mexico the perfect ally to fill the USA with hybrid cars. That is about to end

In his battle for torpedoing every car that comes from outside the United States, Donald Trump’s government has imposed a hard 25% tariff to every car that is manufactured outside its borders. And he has also raised an economic wall for cars manufactured there with pieces from abroad. That measure is especially shocking for Europe, which sold vehicles to the United States by value of 38.9 billion euros in 2024. But, above all, it is for Japan. The country had in United States a sales reef. A huge market that was willing to buy its cars, especially hybrids. It is now in a real problem. Everything that comes from Mexico will have to pay tariffs. Everything that comes from Japan will have to pay tariffs. And its presence on American soil is minimal. The Japanese Balancing Game Complex The automobile industry for Japan is especially important. To understand it, just look at the size of its exports. Until last year, Japan was the country that sold more vehicles outside its borders. His companies have a huge tradition, from giants such as Toyota and Honda to smaller companies such as Nissan or Mitsubishi and others with great recognition such as Mazda or Subaru For its growth, Japan installed new vehicle factories in the United States in the 80s. They produced there but The pieces arrived from Japan So the costs were minor and, in addition, generated wealth in their local market. Now, Donald Trump threatens to destroy that way of working. Before they had already achieved the favor of Americans with good cars in the 60s and, above all, a perfect opportunity with the oil crisis in the 70s. Now the car represents 3% of Japanese GDP but cars sold to the United States added 28.3% of all exports made to the North American country. The impact of maintaining a 25% tariff is such that Reuters He points out that he can impact a 0.2% drop in the country’s GDP. The United States is, for half a century, the main market of its exports in the car market. In 2015, for example, They sold 1.7 million cars In the North American country, for the more than 700,000 units that sold throughout Europe. Its weight is such that in 2023 they sold cars worth 41,070 million dollars to the United States. The figure almost reached that registered throughout the European Union in 2024, when it placed in the US market 38.9 billion euros (42,560 million dollars) in vehicles. They are figures that take into account the production of cars in Japan but, in addition, Japanese firms have found an ally in Mexico in recent years. His proximity to the United States has allowed him to get huge performance to his cars. They offer more affordable vehicles than those sold by local brands and, in addition, they are manufactured at a much lower price. The path taken by Donald Trump has made Jump alarms Within the Japanese government. In fact, the United States already confirmed yesterday (April 7, 2025) that Negotiations with a Japanese delegation opened high level that had been sent to negotiate the terms of the new tariffs. It must be remembered that, in addition to cars, the United States has imposed an added tariff of 24% to all Japanese imports, which is a commercial attack on the largest foreign investor in the country, in data collected by EFE. In Bloomberg They encrypt a 0.59% drop to growth forecasts due to these tariffs. According to calculations echoing ReutersJapan could lose 17,000 million dollars as a result of these tariffs. In Bloomberg They emphasize that American manufacturers do not pay tariffs in the United States for their car sales but claim that strict security measures, among other regulations, prevent them from acting there competitively. It is a case similar to the European where the United States has difficulty selling its cars. On the contrary, the Customer Caladero that Japanese companies have in the United States is huge. Bloomberg points out that 23% of Toyota’s sales worldwide went to the North American country. The figure grows to 28% in the case of Nissan and … at 83% if we talk about Subaru. The country’s weight has been growing thanks to the fact that they have been turning with the Hybrid car salesa Japanese specialty. They are very bad news for brands like Toyota. However, the sanitized accounts of the Japanese giant allows you Reuters. The fall would be 8% for Honda. But the provisioning that Japanese companies make of pieces produced in Mexico They are a real problem for smaller companies or with more gloomy economic perspectives. Mazda and Nissan would be the most affected, with a 59% benefit drop for Mazda and 56% for Nissan. Nissan is, without a doubt, the one who has a more complicated horizon. The company is looking for a buyer who holds him from a dramatic fall in his income that It has taken 9,000 layoffs. The Japanese government has pressed without success for Honda to buy To the company. And now It is Foxconn that positions itself as the alternative that sounds more strongly. Focused on the hybrid car and with an almost testimonial presence among the electric ones, the Japanese need to reach an agreement with the United States urgently. In Europe they need to sell more electric cars if they want to meet the European regulations in 2027 Or, as a minor evil, reach an agreement with other manufacturers. At the same time, In China they have it more and more complicatedsince the market has moved to the electric car. And Chinese competition is, more and harder.
