Satellite images have revealed that China has gathered its most important aircraft carriers. And that can only mean one thing

by

The simultaneous appearance of the two ends of the Chinese aircraft carrier fleet, the Liaoning veteran and the newly incorporated Fujiandocked at the same naval base does not seem to be a logistical coincidence, but rather a carefully eloquent image. One that can only mean one thing: it is training naval “one plus one.” Two aircraft carriers, one message. Satellite images show both ships moored in Qingdaoa port historically linked to the development of Chinese naval aviation and now expanding to accommodate a new phase of maritime ambition. Together, they represent the past learned and the future being rehearsed: the transition from a regional navy to a force of waters blues capable of operating in a sustained manner far from their shores. From symbol to real capacity. China already has the largest navy in the world by number of hulls, but the qualitative leap is marked by embarked aviation. Entry into service from Fujianthe first Chinese aircraft carrier designed from scratch with electromagnetic catapults introduces a capability that until now was only dominated by the United States. In front of him, Liaoning brings more than a decade of operational experience. The coexistence of both on the same dock points to something more than maintenance: it suggests doctrinal integrationknowledge transfer and the practical initiation of group operations with multiple aircraft carriers, a threshold that separates regional navies from truly global ones. Qingdao as a laboratory. Side by side mooring It’s unusual and deliberate.. It coincides with the declaration of restricted maritime zones in the Bohai Strait and the northern Yellow Sea, a classic indication of imminent exercises. Everything points to joint training in which aircraft departure rates, deck security, logistics, command and control, and coordination between air wings will be compared. The objective is not only for Fujian to learn from Liaoning, but to see how two platforms with different capabilities can operate. as a single systemmultiplying its effectiveness. In naval terms, it is not about adding ships, but about creating operational synergies. Beyond the Strait. The Fujian’s movement northward, crossing the Taiwan Strait without aircraft on deck, has been closely followed through Tokyo and Taipei. Precisely this detail reinforces the reading that it is not a combat mission, but rather a training one. The background, however, seems unequivocal: Beijing wants to break the logic of the First Island Chain (the arc that goes from Japan to the Philippines via Taiwan) and demonstrate that it can project power beyond it. Operating two aircraft carriers in a coordinated manner is key to sustain presenceprotect distant sea lines and provide credible deterrence against US aircraft carrier groups. Implicit response to Washington. The Pentagon assumes that the People’s Liberation Army Navy is in the early stages of operating a multinaval force with aircraft carrierprogressively expanding its radius of action. The continued presence of US aircraft carriers in the Indo-Pacific, under the logic of containment and defense of allies, acts as a catalyst for this process. If you will, China somehow seems to say that it does not need to announce a doctrine for the message to get through: the image of two aircraft carriers together in Qingdao communicates that accelerated learning has begun and that the operational gap is closing. The power of tomorrow. There is no doubt, the analysts match in that these movements do not indicate an imminent conflict. But they do reveal patient and methodical preparation. Crew integration, procedure comparison and dual command testing are essential steps for a navy that aspires to operate autonomously in the Western Pacific and beyond. Japan watches it with special attention because you have already seen Chinese aircraft carriers cross its defensive perimeter in recent exercises. Each deployment, each joint training, normalizes what a decade ago would have seemed exceptional. The threshold that China wants to cross. In short, the true meaning of Qingdao is not in the number of tons or the technological novelty of Fujian, but in the sign of maturity. Going from an experimental aircraft carrier to a couple training together is crossing a strategic threshold. It is not the prelude to war, but to status. China rehearses today the choreography that will need tomorrow to hold your global maritime ambition. And in that essay, the message to allies and rivals is clear: the era of the lone Chinese aircraft carrier is behind us, and that of the carrier group has just begun.

How to easily create a nice Christmas greeting with your photo using ChatGPT Images

by

We are going to explain to you step by step how to create a Christmas greeting with your photo wearing ChatGPT Imagesthe section to create images from photographs of ChatGPT. This tool will allow you to do the editing with artificial intelligence without having to write a prompt certain. Right now, this section has a default style that allows you to create a pretty Christmas photo in just two or three clicks. So, to this we are going to add an additional request and voila, you will have the complete congratulations. You’ll see that it’s simple. Your Christmas greeting with ChatGPT The first thing you have to do is enter the ChatGPT website or application on your device. Once you are inside, open the side menu Click on the section Images that will appear just below the search options. This will take you to the main screen of the section Images. In it, look in the section Test a style on an imageand here inside click on the option Festive portrait what you are going to find. This will open a window where you have to choose the photo you want to use as a basis for congratulations. It has to be a portrait-type photo in which one or more people appear. For this, you can use one of the recent ones that you have used in this section, or manually choose another one that you want to use. Just by doing this, ChatGPT will turn your photo into a festive portrait Full of Christmas decorations and motifs. If you don’t like the result the first time, you can try again, and even copy and paste the prompt using another photo, or repeating the entire process. Once you have the image created to your liking, it’s time to give it the final brushstroke. In the same chat where it was generated and shown to you, you have to write that you want me to add a text using a Christmas font. For example, you can put something like “Happy Holidays.” For that, I have used this prompt: I want to turn this photo into a Christmas card. For that, I want you to put the text “Happy Holidays!” at the bottom. using a Christmas font. And only with this you will have your greeting created. Now all you have left is decide if you want to make additional adjustmentssuch as changing the size of the word, its position, or even making the image horizontal. You can even upload someone else’s photo and ask ChatGPT to add it to the composition by doing the same treatment to the photo so that it looks the same.

what it is and how to use it to create artificial intelligence images from your photos

by

Let’s explain to you what it is and how you can use it ChatGPT Imagesthe new section of the artificial intelligence Designed to help you create and edit photos and images. This is a forceful response to Free Nano Banana of Geminiso amazing that it already represents a new evolutionary leap in images created by AI. Since the launch of Nano Banana on Gemini, Google had managed to compete head to head with ChatGPT in creating images from photographs. Gemini was able to use your face and be recognized, something that OpenAI’s AI could not do… until now. We’re going to start by explaining what this new feature is and what features it has to differentiate it from the rest, because there are some very interesting and innovative things. Then, at the end we will summarize how you can use it to create images with different styles from your photos. What is ChatGPT Images ChatGPT Images a new section dedicated to image creation within ChatGPT. This artificial intelligence chat has updated and improved its image creator from photos so much that it has decided to give it an exclusive section. Just as ChatGPT’s normal chat allows you to create images from scratch or from your photographs, This section is exclusive for creating images from photos. Come on, the idea is that when you want to do this, instead of getting complicated by asking ChatGPT, you can enter the section and speed up the process. This is so because In the Images section you will have several ideas for designs and tools to edit your photos. Thus, it will be as easy as clicking on one of your designs, choosing the photo and that’s it, ChatGPT will do the rest. With this, eliminates the need to know how to write a good promptand the process is simpler and more visual for inexperienced people. When you choose the design and upload the photo, it will automatically be sent to ChatGPT with a pre-generated prompt that you can see. Showing you the prompt changes everything This is important, because being able to see the prompt that ChatGPT uses in its presetyou will also be able to copy and paste it to modify it, or even use it in Gemini or some other competing tool. Thus, ChatGPT Images is also not only a good testing ground, but by offering you several prompts it gives you the basis to later generate a much more personalized image from them. You will also know how the image editing prompt works in a more transparent way, and you will be able to use things from both prompts to create a completely unique one. Until now, when you were faced with creating an image from a photo you had to do it from scratch, composing the prompt on your own or searching the Internet to find them. That’s why showing it to you changes everything, because it makes anyone without knowledge can create images very elegant with AI. To all this we must add an interface that also simplifies everything, and in which ideas are shown to you with an image of the resultso that if you see something you like, you just have to click and choose the photo. How to use ChatGPT Images The first thing you have to do is enter the ChatGPT website or application on your device. Here in the side menu Click on the section Images that will appear just below the search options. This will take you to the main screen of the section Images. In it, at the top you have a search field to write a prompt manually, and below you have pre-generated styles of images and ideas of styles or other things you can do. When you choose one of the designs or ideas, you will go to a screen where you simply have to choose the photo you want to use. You can choose any of the last ones that you have used, or click on Choose a new photo to manually upload another photo. And that’s it. When you do so, a chat with ChatGPT will open that includes the photo and the prompt created to generate the type of image you have chosen. In a few minutes you will have the result. You will be able to copy this prompt to reuse it with other images in the chat itself and even modify it to your liking.

Etsy was a haven for crafts and creativity. It has become a minefield of AI-generated images

by

That AI leaves us without jobs It is one of the great concerns of recent years. It is not yet clear what it will be the impact of AI on the labor marketWhat we do know is that There are people doing business taking advantage of generative AI. This is what’s happening on Etsy, where there is an overwhelming amount of “custom art” for sale that is actually made with AI. what’s happening. Etsy is the platform for artists par excellence. Here we can order a personalized portrait of our pet or family in a multitude of styles. Everything normal, except that many of the results if we search for “custom portrait” They are images made by AI. If we look for specific styles that have recently gone viral such as Ghibli, anime or Pixar, AI dominates practically everything. Also, some are not exactly cheap, like this Ghibli style portrait which costs almost 20 euros in digital format. If we want to print it it goes up to more than 46 euros. Why is it important. AI is here to stay and The debate about whether we can consider it art is there. The problem is that, at least for now, the lack of transparency is flagrant. I’ve searched for these types of “custom portraits” on Etsy and have only found a couple of sellers that mentioned the use of AI in the creative process, The rest is not only that they don’t mention it, it’s that they say things like “Original work of art” or “I can’t wait to draw you.” There is a clear intention to hide the use of generative AI. The objective is obvious: to capture an audience that does not know how AI tools work and to whom paying 20 euros for a “personalized portrait” seems like a more than reasonable price. Shall we tell them? AI for everything. Not only do they make the items with AI, there are stores that seem to be managed entirely by one. Some buyers say they felt like they were talking to an AI, which they probably did. There are stores where all the titles, descriptions and comments in response to reviews are clearly made with AI. In fact, Etsy itself launched a few months ago a tool to create titles using artificial intelligence. When you upload an article you can mark that it is made with AI. What Etsy says. Despite the rejection from a large part of the communitythe platform allows the sale of items generated with AI. According to the standards that were published in 2024Etsy considers that the seller continues to provide creativity when designing the prompt, but yes: “Sellers must indicate in the description of their listing if an item has been created with the use of AI.” However, given the volume of unlabeled AI-generated products, it seems they are quite lax about this. More deceptions. In addition to selling AI-generated images by passing them off as handmade, there are other uses of AI to boost sales. We already saw it with the impossible to sew crochet patternsthere are sellers using AI images to promote your products (real) and we have also found it in some Amazon items; It’s the classic “what you ask for vs what you get.” And there is still more. At Idealista they are also using AI in house sale ads “so you can see how it would look renovated.” Vertiginous. At the beginning of the year we talked about the junk AI that was filling Instagram and TikTok; They were very disturbing videos, but it was very evident that they were made with AI. The examples we have given are also easy to detect for a trained eye, but the advances are dizzying. Today, distinguish what is real and what is not practically impossible. Hoaxes like Etsy’s “AI art” will be an anecdote compared to what is to come.

Images no longer mean that something was real. Welcome to the era of permanent visual doubt

by

There was a time, probably less than a year ago, when you saw a picture on the Internet and simply believed it. You didn’t stop to analyze it, or look for its context. You didn’t think “is it real?”, you simply processed it as information, and moved on. That moment will not return. We no longer talk about deepfakes very hardworking people who deceive some journalist (of that We already warned seven years ago). We are talking about something much more banal and therefore more devastating: Your brother-in-law can create a photo in three seconds of you, completely drunk, at a bachelor party you never went to. Your ex can fabricate a photo of you in a pose you never had. A student can generate a compromising image of his or her teacher during the transition between classes. The question is no longer whether the technology is good enough. It is perfect, we are seeing it with several tools and with the recently launched Nano Banana Pro to the head. In fact, it’s too perfectto. And perhaps for the first time, technical perfection has come before social perfection. Who is capable of seeing the photo on the right and assuming that neither the woman nor the waiter nor the bar actually exist? Let’s go having to learn to do something different from what we have been doing all our lives: learn not to be able to trust our eyes. Our entire epistemology—from court testimony to family photo albums—rests on a simple principle: seeing is a way of knowing. Not perfect, but sufficient: For 300,000 years of human evolution, if you saw a tiger, there was a tiger. For 199 years of photography, if you saw an image of a tiger, someone had been close to a tiger. That chain just broke. And it doesn’t break little by little, with warnings and an adaptation period. It breaks suddenly, on any given Tuesday, when you discover that the viral photo you shared was fake and you ate it without hesitation. Or worse: when you discover that everyone has assumed that the real photo you shared is actually fake. What we are losing is not the ability to distinguish what is real from what is fake. That got complicated a long time ago. What we are losing is something more primary: the possibility of operating under the assumption that the visual is, by default, a reasonable starting point. There’s the catch. for a decade we become obsessed with fake news. We were worried about Russian bots, troll farms or organized disinformation. All that was industrial. It cost a lot of money, left footprints and required coordination. What Nano Banana Pro brings is different. It is artisanal misinformation, common at home. You don’t need an authoritarian government or a budget behind it. You just need a smartphone, whatever it is. We could combat industrial misinformation with fact-checkers and media literacy. How do you combat the fact that each person is now a printing press for alternative realities? How do you verify 10 billion images daily? You can’t. The least obvious consequence is the most devastating: we are going to beg for a lock next to our real photos. If anyone can make any image, only those with verifiable certification will matter. Encrypted metadata, digital chain of custody, institutional authenticity seals. Anything, but something. The photo without a stamp will be suspicious by default. Who is going to offer that certification? Google, Meta, Apple, maybe governments. The only institutions with resources to verify on that scale. We are going to pay them for something that has been free for two centuries: the presumption that what was photographed existed. Because the alternative – a world where no one can be sure of anything – is simply unlivable. But The worst thing is not losing confidence in the images. It is losing confidence in memory. Your brain doesn’t store experiences, it stores reconstructions. And every time you remember something, you reconstruct it with the help of fragments: smells, emotions, images. Photographs have been crutches for memory for decades. They consolidated the rest of the memory. And then there is exhaustion. Every image you see now requires a little evaluation. Is it real? Do I verify it before sharing it? Will I look like a tolili if I send her to the group? Another tab for our internal CPU. Our parents never had to do this cognitive work. We are going to spend the rest of our lives in suspicion mode. Not because they are cynical, but because they are rational. That permanent suspicion has a cost. In attention, in mental energy. Perhaps in a capacity for wonder. In the possibility of seeing something extraordinary and simply believing it. Never again. There is hardly a solution for this: You can’t train an AI to detect AI-generated images perfectly: it’s an infinite arms race. Each detector upgrades the generators. Each generator improves the detectors. Each higher wall is an incentive to lengthen the pole. You can’t educate people to “think critically” on each of the thousands of images it processes per day. We don’t have bandwidth. and nor you can legislate the problem because technology is faster than the law and more accessible than any prohibition. The only thing left is adaptation. Cultural and psychological. Our grandparents trusted what they saw. We trusted what was photographed. Our children are not going to trust anything that does not come certified. Maybe the blockchain It was also invented for this. AND When everything needs verification, nothing can be spontaneous. When every image is suspect, none is memorable. When reality requires constant authentication, we stop inhabiting it naturally. Photography died the day it became indistinguishable from the imagination. We will continue taking photos and we will continue seeing them. But They will no longer do what they did for two centuries: tell us what was real. Welcome to the era of permanent visual doubt.

Idealista is filling up with images of houses for sale made with AI. And it’s getting harder and harder to identify them.

by

AI-generated content has flooded everything and it is becoming increasingly difficult to distinguish it. The call AI Slop It is everywhere; in social networks, on Spotifyin Wikipedia…even in niches as specific as that of crochet patterns. This avalanche has made us distrust almost any image that we see online, also if you are looking for a house, just because: Idealista has also been filled with AI. house catfish. We typically use the term when a person on the Internet impersonates another person and lies about their appearance. This is what is happening on some real estate sales and rental platforms. Wired already showed some cases of images altered with AIbut it is not a trend exclusive to the United States, on platforms such as Idealista and Fotocasa many ads are also appearing with images modified with AI tools. “So you can see how it would look.” It is the excuse that many owners and real estate agencies use. What they do is enhance the photos using artificial intelligence tools so that the property appears newer than it actually is or how it would look renovated. in the advertisement what this user reports in Xthey have used AI in the image of the pool to show what it would look like if the water was clean and everything was in perfect condition. In the responses to the same post, another user shows this other ad where they have used AI to put grass in the garden of the house, with a pretty bad result by the way. What you ask for vs what you get. Click on the image to open the publication in X. More eye-catching ads. In the description of the ads that users report, they warn that AI has been used to retouch some images, but what they usually do is put the images with AI first to attract the attention of those interested. Once inside the ad, you find reality: the house is falling apart. If it is specified in the description and then they put the real photos, it is not technically a scam, but it is a rather shady strategy that adds another layer of difficulty to the already difficult task of finding a house to buy or rent. Undetectable. The first image generators were not useful for making modifications because images were basically invented, but The arrival of Nano Banana was a turning point since it allows changes to be made while being consistent with the original photo. In September Images appeared on Idealista with the Gemini watermark. We cannot know what they have removed or added, but it could be used to remove moisture or some defects without it being obvious that they have used AI. In this specific case they have left the watermark, but there will be many people who do not know what it means, not to mention that removing it is very simple. There may be many more AI-modified images that are undetectable. Idealista promotes it. In 2023 the platform published an article explaining how to take advantage of AI tools to fix ad images. They showed examples such as organizing rooms, filling swimming pools or furnishing empty rooms. They also launched ‘smart text’ to generate descriptions of the properties, a function similar to those found on other platforms such as Wallapop. Recently published another article where they warned of scams on their platform using fake image generation with AI; a confirmation that it is a fairly widespread and not always transparent practice.

How to create a character in ChatGPT and Gemini to use it in all the images you make with artificial intelligence

by

Let’s explain to you how to create a character in ChatGPT and Gemini., and tell the AI ​​to remember it so you can then use it in all the images you generate in that conversation. Thus, if you want there to be cohesion between all the images, and for them to be starring the same digital person, you have a way to do it. We are going to briefly explain three different ways in which you can do it, telling you step by step the process you must follow. Remember that it is best to do everything in the same chat to maintain context. Create a character from a description The first method is to tell it that you want to create a character and add a skin description that you want to use. Start the prompt by telling them that you want to create a character called “name”, and then tell them in detail about their physical appearance and clothing. This method usually works best in ChatGPT. The AI ​​may then ask you questions to clarify, such as the style to use, and you must answer as you prefer. In my case, I have asked him to make me a comic-style one. An image will then appear, and you can ask it to make changes if you want to the design. Now, you can add a prompt with which set the character’s appearance. For that, you can use a prompt like “I want you to set this appearance to the “name” character, so that if I ask you for more drawings of him, you will always use the same design. Okay?”. With this, ChatGPT or Gemini should save this aspect. Now you can start ask you to draw this character in different ways. To do this, literally ask them to draw (name of character) and describe the scene and what they are doing. You should make the image keeping the same style of the drawing and exactly the same appearance. Create the character from a photo You can do exactly the same, but creating your character from a photo rather than from a description. Simply ask them to reimagine the photo and add a description if you want to change something or add more things, such as the outfit. Then ask him again to make it a character to use from now on. And then, just ask him to create the same character in different scenes. This method does not always work well in ChatGPT, and it usually works worse in Gemini, but it is something worth exploring. Use an already created image And the third option is use a character that you have created on another website or AIor in short any external design. To do this, upload the drawing of this character and add a prompt like “I want all the images I ask you for in this specific chat from now on to use this character as the protagonist”. This alone will be enough. And from now on, simply go asking me to create an image with a person doing what you want in the environment you describe. The image will be generated, but using the character you created before as a reference. Here, this usually works best with Gemini.

If with the Fujian it sat at the US table, the images of the next aircraft carrier place China in another dimension: the nuclear one

by

Last week China announced its first 100% national aircraft carrier hitting the table and making it very clear what its naval aspirations are. Now the appearance of new images from the Dalian shipyard has revived one of the most significant naval movements of the 21st century: China’s advance towards an aircraft carrier that places it at an unknown level. The strategic leap. We are referring to what aims to be the first nuclear-powered one, provisionally known as Type 004. He visible discovery of a structure reminiscent of a reactor compartment (similar to those found on US supercarriers) suggests that Beijing is taking the definitive step towards a capability that until now only the United States and France have. The transition is not symbolic, but structural: A nuclear aircraft carrier offers virtually unlimited autonomy, massive electrical power for advanced sensors, and sustained ability to operate further from shore, an essential element for a China that aims to project power beyond its immediate periphery. The Fujian catapult. The recent entry into service from Fujianits first aircraft carrier with electromagnetic catapults had already marked a break with the It was STOBAR.but Type 004 represents a technological leap even greater by integrating nuclear propulsion with the most advanced launch ecosystem that the Chinese navy has. Even so, Chinese naval planning appears to bifurcate: as it builds this ambitious vessel, reports indicate who also works in another conventional aircraft carrier improved, a sign that Beijing wants a combination of mass and elite to accelerate its naval transformation. On new aircraft carrier under construction Comparative architecture. The reason why Type 004 arouses so much attention is that, in its designconcentrates the synthesis of global trends: a helmet inspired by the lines of the American Ford, EMALS catapults similar to the North American and French ones, and a deck capable of operating from J-35 stealth fighters even naval drones GJ-11 or airplanes AEW&C KJ-600. The satellite images reveal a deck under construction that will include two catapults in the port area (in addition to two in the bow), matching the layout of American ships and surpassing the capacity of Fujian itselfwhich only has a catapult in the oblique section. Extra ball. The vision of the program is clear: provide the Type 004 with a heaviest air wingvaried and technologically complex, optimized for sustained operations and for air and maritime space control roles beyond the Chinese coastline. The parallel development of a possible “Type 003A” conventional (cheaper, faster to produce and based on an already dominated architecture) demonstrates how China combines disruptive innovation with industrial iterationensuring sufficient volume to saturate any attempt at regional containment. If nuclearization provides range and resilience, the simultaneous construction of conventional ships ensures pace and fleet density. Unlimited energy. Plus: its function is not only to move aircraft further, but to serve as an energy platform for a set of emerging weapons that would transform naval warfare. Official voices, such as Professor Liang Fang of the National Defense University, they claim that the future Chinese nuclear class could carry directed energy weapons (including high-power laser weapons and the long-awaited electromagnetic cannon or rail gun). These weapons are not mere futuristic add-ons: they require colossal amounts of energy and an electrical stability that only a naval nuclear reactor can offer. He rail gunbased on the acceleration of metal projectiles to hypersonic speeds using electromagnetic fields, is a system that the United States abandoned due to costs and technological maturity, but that China continues to develop as part of its strategic disruption. And more. Its appeal lies in exit speedthe lack of explosive and the possibility of devastating kinetic impact at low cost per shot, although its electrical consumption is gigantic. The convergence between nuclear aircraft carriers and electromagnetic weapons aligns with the plans already outlined by figures such as Admiral Ma Weimingresponsible for the PLA’s electromagnetic program, and represents a clear attempt to turn a flagship into a technological node capable of challenging US naval dominance in emerging domains. The operational dimension. TWZ analysts recalled that the future Type 004 air wing combines aviation advanced manned and drones large in size, creating a hybrid system Designed for offensive projection and situational awareness over an extended range. The integration of stealth drones like the GJ-11, heavy AEW&C aircraft like the KJ-600, and fifth-generation J-35 fighters would allow China to adopt an operating model closer to the American one: extended air-to-air combat, persistent surveillance, distributed electronic warfare, and deep strike capability. Added to this are the new amphibious ships Type 076 (also equipped with electromagnetic catapults to launch drones) that would complement the aircraft carriers with saturation functions, regional air control and operations support directed towards Taiwan or the South China Sea. The result is, a priori, a navy that, although still inferior in number to the eleven American supercarriers, closes the gap with a unprecedented speed. China and the new balance. In summary, Type 004 symbolizes a decisive strategic shift: China is no longer just modernizing its fleet, but aspires to equal the autonomy, technological capability and global reach of US aircraft carriers by combining nuclear poweredelectromagnetic weapons, high energy lasers and a new generation embarked aviation. The visible integration of the reactor module in Dalian confirm that Beijing seeks to operate a type of super aircraft carrier capable of sustaining prolonged ocean missions and powering futuristic systems that could redefine naval warfare. At the same time, the parallel development of another conventional model demonstrates a dual strategy that seeks volume and sophistication at the same time, quickly reducing the gap with the US Navy. In other words, China is moving towards a maritime architecture based on abundant energy and dominion of the electromagnetic spectrum, a change that forces us to completely rethink the global competition for control of the seas.

A Harvard astronomer has accused NASA of hiding 3I/ATLAS images. has an explanation

by

Avi Loeb, the controversial cosmologist of Harvard University, has accused NASA of withholding important data on the interstellar comet 3I/ATLAS, and is mobilizing the US Congress to demand its release. But this alleged concealment of evidence is not what it seems. Weeks without seeing the photos. In one post on your blogLoeb denounces that NASA has not made public images of the object taken with the HiRISE camera of the Mars Reconnaissance Orbiter probe from Mars orbit for weeks. These images, captured between October 2 and 3, when 3I/ATLAS passed within 30 million kilometers of the red planet, are, according to Loeb, “extremely valuable” scientific data. The reason is that they would have a resolution of 30 kilometers per pixel, three times greater than the best available image of the interstellar object, taken by the Hubble Space Telescope. This “side perspective” could be important for understanding the object’s geometry and its brightness, so Loeb asked US Congresswoman Paulina Luna to demand that NASA’s acting administrator, Sean Duffy, release it. The explanation. NASA has justified the lack of images with a very earthly argument: the delays caused by the closure of the United States government since October 1. NASA is officially on “shutdown” and with 83% of its staff on unpaid leave due to the lack of agreement in Congress on the 2026 federal budgets. Only the International Space Station control room and the operators in charge of ship and satellite security, as well as a handful of critical jobs, continue to function. The rest (a large part of science, dissemination, aid processing, etc.) is on pause. Why so much interest in 3I/ATLAS. Comet 3I/ATLAS is the third interstellar object detected in our solar system. Since its discovery, it has shown behavior somewhat disconcerting which has led Avi Loeb to defend the hypothesis that it could be an artificial extraterrestrial object. The latest anomaly occurred near its perihelion (the closest point in its orbit to the Sun) on October 29, when 3I/ATLAS shone brightly in blue and experienced an acceleration which cannot be explained by the gravity of the Sun. Most likely? That the comet was degassing as it warmed up, and the sublimated ice acted as propellants. If you don’t pay attention to it you get bored. Loeb has calculated the possibility that 3I/ATLAS is a natural object: “less than one part in ten quadrillion”. The astronomer highlights the trajectory almost perfectly aligned with the plane of the planets, an unusually large mass, a very low proportion of water (only 4%) and a surprising abundance of nickel as evidence. But this is not the first time that Loeb has proposed that an interstellar object is a technological and “possibly hostile” object. In fact, it’s the second time he’s done it (the first with ‘Oumuamua), and we only know of three interstellar objects that have visited our solar system. The scientific community does not play along. Compared to Loeb’s hypotheses, the vast majority of astronomers offer much more mundane explanations. The blue glow is consistent with emissions of ionized gas from other active comets. Other physical characteristics could be explained if 3I/ATLAS were the ejection of a piece of exoplanet by a natural collision far from Earth. As for the news that “NASA” activated its defense protocol against 3I/ATLAS, it also has a simple explanation: the International Asteroid Warning Network has chosen measure the position of the interstellar comet for an observation campaign that had been planned since 2024, not with the aim of defending ourselves from. an alien attack, but to improve astrometry systems.

How to force Gemini to create images of proportions and sizes you want instead of always making them square

by

We are going to explain how to get it Gemini make images with the sizes and proportions that you want. With other alternatives such as ChatGPT This is as easy as telling the horizontalxvertical pixels or telling you an image aspect ratio, but with Geminithe artificial intelligence from Google this seems to fail, and often just makes them all square no matter how much you ask otherwise This is a bug that will surely be corrected over time, but if you need to have control over the proportion of the image you are going to create, we will tell you a little trick with which to force it in an original way. Create images in the proportion you want The first thing you have to do is edit a blank image with the proportion you want using any image editor. You can simply make a blank image and crop it to use a specific size. It could also be a random photo, because in the end it’s just one size template which you will then use in Gemini. Now you have to go to Gemini. When writing the prompt you have to add blank image with size that you have chosen. It will be like putting the canvas on which to later create the image. Then, next to the image add a prompt with this formula: “Replace this image with one that shows (…)”. Here, in the prompt it is important to specify that you want replace that image with a new oneand then describe what you want to appear in the new drawing. By doing this, Gemini will not create the image entirely from scratchbut instead will take as reference the size from which you have uploaded. And then, since you have asked to replace the image, nothing from the previous one will appear, but to avoid problems it is best to have the image blank. This way, you can master one of Gemini’s biggest flaws when creating images, which is that it ignores your size instructions. And remember that you can have several templates of specific sizes.
