The hot Jupiters are evaporating, their winds reach 7 km/s and yet something is slowing them down

by

The hot Jupiters They are fascinating planets. They orbit so close to their star that they sometimes have orbits of less than a day. Solar radiation is very high, so much so that sometimes these planets are practically evaporating. And they are usually tidally locked. That is, they have one face always facing the Sun and the other always facing the opposite side. As a result, one side is much hotter than the other and receives more radiation, so the gases in its atmosphere ionize, transforming into plasma and moving at high speeds. Put very briefly, they have the strongest winds of all the known planets. However, recently a team of scientists led from the Côte d’Azur Observatory in France, has discovered something very strange. Seven hot Jupiters in which the winds flow much slower than expected. The only explanation that seems logical for this phenomenon is that they are surrounded by a magnetic field. And it is great news, since, if confirmed, it would be the first detection of magnetic activity beyond our solar system. Totally counterintuitive. The speed of a planet’s winds can be measured by tracking the vaporized iron present in the gases in its atmosphere. The authors of the study that has just been published did so with 7 hot Jupiters thanks to two instruments: MAROON-X, from the Gemini North telescope, and ESPRESSO, from the Very Large Telescope (VLT). When analyzing the results they saw that these planets had very high speeds, between 2 and 7 kilometers per second. The winds of our own Jupiter, the fastest in the solar system, are 0.4 km/s, to give us an idea. What happens is that these winds went slower the hotter the planet was. One of the authors of the study, Vivien Parmentier, has rated it as something “totally counterintuitive”, since the logical thing is that the higher the temperature, the faster the wind flows. The key must be in the presence of a magnetic field. In fact, with all this temperature and speed data, they have even been able to calculate its intensity. The thing is about temperatures. Generally, the higher the temperature, the greater the difference between the dark and light sides of the planet and the more excited the ions in the plasma are, so the wind generally moves faster. The logical and expected thing would be that the higher the temperature of a hot Jupiter, the faster its wind. The speeds are very high, but much slower than expected. Furthermore, they are slower the hotter the planet is. The best explanation for this event is the presence of a magnetic field. Magnetic activity and wind. When a magnetic field acts on a moving charged particle, it is affected by something known as the Lorentz force. Very briefly, what happens is that the speed changes direction. The particle does not stop, but goes from flowing freely to being confined within the magnetic field. Every time he encounters his lines, they make him change direction. If we see this as a whole for the entire plasma, since it cannot move freely, its speed decreases. This would explain why a magnetic field was slowing down the wind. But why does it brake more the higher the temperature? Auroras on Earth The secret is inside. The magnetic field of a planet is directly related to the movement of the liquid metals inside it. For example, in the case of Earththe movement of molten iron and nickel on the outside of its core generates electrical currents, which give rise to a geomagnetic field that extends into space. They are responsible for us having that magnetic field that protects us from the sun’s inclemencies. The higher the temperature of a planet, the more violently the molten metals inside it move and, therefore, within limits, the more intense the magnetic field will be. In turn, the more intense it is, the more it will slow down the winds. Possible auroras. The location of auroras on Earth is related to the magnetic field. Another of the authors of the study, Bibiana Prinoth, points out that she likes to imagine that one of these Jupiters has a sky “covered by curtains of colorful light that dance over a planet that is half in perpetual day and half in endless night.” What is it for?. Now that we know that some exoplanets have a magnetic field, we could also take it into account when selecting habitable planets. Logically, hot Jupiters are not candidates at all. However, other less inhospitable planets may also have this protective shield. We already know that it is not enough to just be in the habitable zone. Other qualities, such as housing a sufficient amount of water either be far from supermassive black holes These are conditions that can help us refine the search much better. Each new discovery brings us a little closer to that great discovery. Image | Gemini International Observatory/NOIRLab/NSF/AURA/M.

SpaceX wants to reach a capitalization of 1.75 trillion dollars. Analysts are clear that it is worth less than half

by

SpaceX’s is the first of the record-breaking IPOs that are expected this year: it will take place on June 12, 2026 under the symbol SPCX. This operation promises to be the most important public offering of shares in history, and the company has already indicated that its objective is to obtain funds worth $75 billion to achieve an astronomical valuation of 1.75 billion euros. But how SpaceX is valued is one thing, and how analysts value it is quite another. Overrated. The financial analysis firm Morningstar has carried out an analysis of SpaceX’s financial accounts and have reached a striking conclusion: “We believe the company has been significantly overvalued and investors will have the opportunity to buy the shares at more attractive levels after the IPO.” Or what is the same: they advise not participating in that initial IPO, and waiting because they anticipate that the stock will fall in the first days on Wall Street. It’s only worth half. In these conclusions, Morningstar establishes that the valuation discounting SpaceX’s cash flow is $780 billion. That represents 48% than the valuation of the private market, which is 1.5 trillion dollars, and 44.5% less than the valuation attributed to the company itself, which amounts to 1.75 trillion dollars. Is it really more promising than Nvidia? Dan Coatsworh is one of the main analysts at the firm AJ Bell, and he commented on CNBC how that theoretical internal valuation of $1.75 trillion would mean that the value of SpaceX (P/E, Price to Earnings ratio) is 67 times its sales, two times more than, for example, happens at Nvidiathe most valuable company on the planet today. Beware of xAI. One of SpaceX’s theoretical strengths is its artificial intelligence division, xAIbut analysts explain that in reality its theoretical advantage is “undetermined”, and in fact they pose it as “a material threat of value destruction” for the parent company, SpaceX. Morningstar believes that the AI ​​division is worth $170 billion, and that what really matters is something else. The Starlink engine. SpaceX’s real argument for going public and its real strength is not the reusable Falcon 9 rockets, but the profitability of Starlink. The company’s satellite constellation has achieved sustained cash flow in recent months, and its global customer base is growing at an enviable pace. It is undoubtedly SpaceX’s great recurring revenue generation machine. Morningstar values ​​it at $611 billion. The double class trick. SpaceX plans to sell shares at a fixed price of $135 per share, but they will only list 3% of the total shares. In addition, Elon Musk will continue to maintain tight control of the vote with 85% of the total through a dual-class share system. Class A shares, those that go public, allow the right to one vote per share. Class B shares go to the founder and the first key investors. They are not sold on the open market, and each one usually gives 10, 20 or more votes. Institutional dependency. The value of the company, however, is supported by the contracts it has with the US government. Specifically with NASA and with the Department of Defensewhich depend entirely on SpaceX systems for their critical missions. That not only guarantees long-term income, but is a compelling argument to attract more conservative investment funds. Either you believe Elon, or you don’t. We are facing an operation that will test Elon Musk’s real power over the markets. Although SpaceX is an extraordinary company, it is overvalued due to its founder’s habit of selling hype.

reach 600 km of autonomy

by

The largest battery manufacturer in the world already has a date to make the definitive leap to sodium batteriesa chemistry that has been promising for years to unseat lithium in the entry-level range. Wu Kai, chief scientist at CATL and member of the Chinese Academy of Engineering, confirmed at the Equipment Powerhouse Forum, held on May 30, that the manufacturing problems that were holding back production are now resolved, according to they counted from the Chinese media Sina. The goal is to reach 600 kilometers of autonomy on a single charge. Why does it matter? Sodium is much more abundant and cheaper than lithium, so each battery made with this chemistry reduces dependence on a scarce and volatile raw material. For the consumer, this may end up translating into more affordable prices for the electric car, precisely in the segment where the electric car dominates today. lithium iron phosphate (LFP). Of course, for CATL these batteries would be intended to rival the entry-level LFPs, but they will not be a substitute for the premium segment. In detail. The company is not going to limit sodium to just one product. Your roadmaps they point to integrate it into passenger cars, commercial vehicles, battery exchange networks and energy storage infrastructure. The first versions will be used for economical cars and storage systems, while the company is simultaneously developing higher density cells to get closer to that 600 km figure that is currently reserved for more expensive configurations. The news follows a recent milestone that saw CATL close a 60 GWh supply contract, the world’s largest order for sodium batteries to date, according to they point from CarNewsChina. Competence. All of this is happening while CATL crushes the competition in traditional chemistries. According to data of China EV DataTracker, in April 2026 installed 29.06 GWh of batteries for electric vehicles, giving it 46.6% of the national market. Of that volume, almost 19.53 GWh were LFP and 9.53 GWh were nickel-manganese-cobalt ternary packs. Sodium does not replace these lines, but rather opens a parallel production path. Between the lines. It is worth remembering where this comes from. CATL has already presented its Naxtra range of sodium batteries, with a version for passenger cars that reached 175 Wh/kg of energy density, the highest recorded in this chemistry, according to the company itself in 2025 and promising about 500 km of autonomy and more than 10,000 charging cycles. In addition, sodium provides a safety advantage, since by eliminating materials prone to combustion, it reduces the risk of fire compared to other chemicals. And now what. Sodium is just the short-term part. Looking ahead, CATL is already reorienting its research towards lithium-air batterieswhich use oxygen from the air as a reagent and promise energy densities much higher than those of current systems, whether liquid or solid-state electrolyte. We will have to wait to find out more information about it. Cover image | CATL In Xataka | Starting in July, all new cars manufactured will incorporate an annoying novelty: many more beeps

Elon Musk not only wants to reach the Moon, he also wants to turn it into a factory for satellites launched with catapults

by

What do they have in common ChinaSpaceX, Auriga Space and Electromagnetic Launch? Well, possibly several things, but one of them is that they have expressed interest in using mass cannons to launch from the Moon. Said to very roughlywant to use electromagnetic catapults loaded with satellites or construction materials to other points in space. Today, existing technologies are not optimized to launch large loads, but with so much power involved it would not be strange if it were finally achieved. The ethical implications would be many even if they only focused on science and communications. However, it could be even worse; Well, according to the analysis recently published by an expert, the arrival of the military applications It would only be a matter of time. From moon rocks to nuclear warheads. The idea of ​​the lunar mass cannon He initially proposed it a scientist named Gerard O’Neill in the 70s. His idea was to use them to extract minerals from the Moon and launch them into space to build space colonies with them. Over time, many space agencies, public and private, have become interested in its use. For this reason, the independent analyst specialized in cislunar security Andre Sonntag just published a report in which he recounts the risks that these catapults would entail. If the necessary technology is optimized to launch large payloads, they could be used to launch probes aimed at destroying satellites, inert projectiles and even ships loaded with nuclear warheads. Furthermore, if launches are made from the Moon they may be more difficult to detect by conventional early warning systems, so many attacks would go unnoticed. An ingenious design. Mass cannons are actually very interesting systems for space launch. They consist on a track in which one electromagnet is placed after another. A metal cart is circulated above and is attracted by said magnets. Each of these electromagnets is activated just when the car passes over it, giving it a new impulse, so that it accelerates more and more. The goal is to reach 2.4 kilometers per second, since this is the speed necessary to escape from the Moon. When this is achieved, the cargo on board the car is launched into space. In short, it is possible to catapult what is inside the car without having to consume propellant. Better on the Moon. This system has historically been proposed for use on the Moon for two reasons. To begin with, unlike what happens with a conventional rocketa very high speed is reached very quickly. If the process were done on Earth, the rocket would reach the atmosphere so quickly that it would catch fire due to friction when crossing it. On the other hand, there is no classical atmosphere on the Moon. On the other hand, since gravity on the Moon is much lower, a lower speed is needed than what would be needed to escape through this system on Earth. The case of Elon Musk. In his report, Sonntag has not mentioned any company or agency. However, it is well known that Elon Musk speak of the use of these mass cannons last February. He has been expressing his interest for a long time establish data centers in space and manufacture AI satellites directly on the Moon. This would avoid the energy, thermal management and launch logistics limitations that Earth poses for its ambitious plan. The vacuum of space would serve as a coolant and solar energy could be used to obtain electricity. The release waiting listIn addition, it would be much clearer than on Earth. In order not to have to carry large amounts of fuel to the Moon, their idea is to launch these satellites directly from our satellite. That is why he has already mentioned electromagnetic catapults on several occasions. There is legislation, but it is difficult to ensure. The United Nations Outer Space Treaty strictly prohibits the construction of military installations on celestial bodies. It also prohibits nuclear launches from space. However, Sonntag points out in his report that it would be quite difficult to verify. Therefore, he is concerned if these types of systems advance, given the interest of tycoons like Elon Musk. The payloads that could be launched with current technologies are minuscule. In fact, launching functional satellites directly with one of these cannons is science fiction. However, technology will advance. By then, we must be prepared, because those who have no scruples on Earth will not have them in space either.

‘Star Citizen’ has managed to reach $1 billion in financing. We have no idea when it will be released

by

There are video games that fall behind, video games that change course, and video games that seem to live in a category of their own. ‘Star Citizen‘ clearly belongs to the latter. What we have seen for more than a decade is not only the development of an ambitious space simulator, but a phenomenon that is difficult to fit into the usual molds of the industry: thousands and thousands of players financing a promise that continues to grow without there being yet a closed date for its full commercial launch. A figure that is difficult to ignore. The official website of Roberts Space Industries places funding ‘Star Citizen’ at $1,011,412,026, with 6,560,271 Star Citizens registered at the time of capture contributed. We are not talking about an estimate or a figure reconstructed from outside, but rather the public accountant of the project itself. This data allows us to better understand the magnitude of the phenomenon: a community that has not only closely followed each progress, but has also financially supported one of the most ambitious and prolonged bets in modern video games. Fourteen years of waiting. The origin of the project helps to understand why this case has become so unique. ‘Star Citizen’ began to take shape in 2012when Chris Roberts, known for ‘Wing Commander’, co-founded Cloud Imperium Games with Sandi Roberts and decided to finance development directly with the community. The game was originally aimed at 2014a reference that today serves to measure the distance between that first ambition and the current state of the project. Open development as fuel. The study has not maintained interest only with an initial promise, but by showing the process almost live. We have seen a development accompanied by weekly broadcasts, blogs, roadmaps and early access to the alpha, a way of working that has made the community a visible part of the project. Sandi Roberts also points to that link when she talks about AMAs on Reddit, forums and ‘Bar Citizens’ events, gatherings organized by fans themselves. It’s not finished, but it’s not empty either.. It is convenient to separate two ideas that are often mixed. ‘Star Citizen’ does not yet have a full commercial version, but those who support the project You can now play an alpha with available content on PC. In its current state, the project allows for bounty hunting, mining, large-scale industrial transportation, medical rescue, and ship recovery. Ships, promises and thousands of dollars. The financing model also has a particularly striking side. Many of the highest-value contributions are tied to ships associated with the game, with options that can start at $15 and others that run into the thousands. The most recent example is the Anvil Odina ship worth more than $5,000. Also, there is an important nuance: it is a “concept pledge”, so it is not yet available in the game. The final stretch remains undated. In parallel to ‘Star Citizen’, Cloud Imperium is also working on ‘Squadron 42‘, a single-player campaign set in the same universe and with a cast that includes several figures. ANDn statements to VarietyChris Roberts assured that the team is in the final phases, although without a fixed schedule. Therein lies the big unknown: the project has reached an enormous scale, but we still don’t know when version 1.0 will arrive.

“Whoever contributes 40 years at the maximum does not reach 50% of what they contribute”

by

The Spanish pension system works, in theory, under a simple principle: the more you contribute during your working life, the greater the pension you have when you reach contribution. That’s the theory that works in most cases. However, Alfonso Muñoz Cuenca, an official specializing in pensions, has published a video in which a paradox is revealed within a system that prioritizes the principle of solidarity, compared to that of contribution that should reward those who contribute the most with higher pensions. The limits that change everything The Order PJC/297/2026 which came into force in March 2026 has set the maximum contribution base to the General Regime sets in its article 2 at 5,101.20 euros per month for 2026. In parallel, the maximum pension that a retiree can collect that same year is 3,359.60 euros. That is to say, between what a worker can contribute in his monthly contributions and what he can receive when he retires there is a difference of almost 1,742 euros per month. Muñoz explains that the contributory principle applied by Social Security establishes a relationship of proportionality between what a person contributes to the system and what they receive as a benefit. Whoever contributes more, in terms of amount and duration, effectively tends to receive a higher pension. However, the legal limit conditions the entire calculation, and this limit leads some contributors in the highest percentile to wonder if they are really interested in contributing for the maximum base. As the official himself points out, answering that question “is very complex and has many nuances.” Everything is better understood with examples To explain that contributing for the maximum base is not always “giving money away,” Muñoz explains three assumptions with different conditions that can occur throughout a working life. The expert points out that this career can be very stable and for many years in the highest range of contributions, but life is inexorable and there may be periods with lower salaries, intermittent unemployment, etc. The first of the cases that Muñoz exposes is that of a retiring worker at 65 years old with 40 years of contributions, practically all of them contributing at the maximum of the contribution base. By law, that worker would be entitled to 100% of the regulatory base, which is equivalent to a theoretical pension of about 5,100 euros per month. The problem is that, by applying the limit that the last legal reform, the worker “will be able to collect the maximum pension, which is 3,359.60 euros,” says Muñoz. That is, in this case, the case is observed an imbalance of almost 2,000 euros between the base for which you have contributed for a good part of your working life and the pension you receive when you retire. The second assumption uses that same worker with 40 years of contributions, but in this case, he has had periods with lower salaries, part-time work, contribution gaps or years receiving unemployment benefits, contributing for the maximum base while he has been able to fulfills the function of a buffer for those ups and downs. That is, it contributes to raising the regulatory base on which the pension is calculated because the periods with “excess” contributions compensate for those with “deficits.” When contributing more does not pay off: early retirement For the third assumption that the expert explained, which is the one that most highlights the anomaly that can most discourage those who contribute the most, Muñoz simulates the work life of two workers with different contribution files. In the simulation of the first worker, an employee is shown who has accumulated 40 years of contributions with the maximum contribution base, and poses a early retirement at 63 years old. For retiring two years early, Social Security applies reducing coefficients (unless you belong to one of the exempt unions). In this case, a 19% reduction is applied, which would leave you with a theoretical pension of 4,132 euros. However, when the maximum pension allowed is exceeded, these coefficients are not applied to the theoretical pension, but are applied directly to the established limit (3,359.60 euros), so the final pension would be about 2,721 euros. By applying the 20.42% personal income tax withholding that corresponds to the income, the resulting pension is 2,165.59 euros. That is, a difference of 2,935.61 euros with respect to the contribution base that you have been paying during your working life. Worker two in this simulation, on the other hand, has only contributed part-time for 15 years and does so for a base of 1,100 euros per month. However, he retires at 65 and has a dependent spouse. For your years of contributions, you are entitled to 50% of the regulatory base, that is, 550 euros. By not reaching the minimum pension, Social Security recognizes the corresponding supplements for receiving a retirement for below the minimum amount. so your resulting pension is 1,127 euros per monthand is not subject to personal income tax withholding. The expert’s conclusions are devastating: “The first worker has contributed to the system for 40 years with very high contribution bases and does not receive even 50% of what he contributes.” On the other hand, the second, having contributed for only 15 years and for a much smaller amount, receives more than 100% of what he has contributed.

Without gas stations in space we will not reach Mars. NASA knows this and is finally doing something about it

by

Much of a spacecraft’s fuel is consumed in maneuvers to leave Earth’s orbit. For this reason, as manned missions move further away from our planet, we must begin to think about use space gas stations. These are not fuel pumps floating in space, but satellites, or even ships, capable of transferring fuel to a ship that needs it to travel further. At the moment, this is one of the weak points of many missions, so it is important to start working on technologies that allow it. At NASA they are very aware of this problem, hence this year they are going to launch LOXSATa mission that will test 11 different technologies to guarantee the transfer of propellants. 9 months ahead. LOXSAT is a NASA mission in collaboration with the company Eta Space. The objective of this mission is to test different cryogenic fluid management technologies so that in the future propellant tanks can be created in space. The mission will remain in low Earth orbit for 9 months. Meanwhile, 11 technologies will be tested focused on achieving four objectives: reducing boiling, improving propellant transfer, maintaining stable pressure and measuring propellant levels. The big problem. Cryogenic propellants, such as liquid oxygen at extremely low temperatures, are very efficient, but they have a major disadvantage. And in microgravity conditions, when the transfer between ships is carried out, the temperature cannot be kept low enough, so the fuel boils and suddenly transforms into gas. This causes a huge increase in pressure, which can endanger the ships involved. It seems to be that precisely this problem is the one that is giving SpaceX the most headaches. Like Blue Origin, this company must demonstrate its ability to refuel in space to be part of the Artemis missions, but it is not being easy. This is the reason why with LOXSAT methods will be tested to maintain stable pressure and reduce boiling. Space gas stations. The objective of this mission is to perfect the technology so that in the future there can be fixed propellant tanks in space. In other words, they hope that as we colonize space terrain we have gas stations so as not to run out of fuel. China on the heels. Ideally, in the future, large ships could exchange propellant. No space agency has achieved anything like this. However, China has indeed achieved it with satellites, in their Shijian missions. Plus, they did it in a higher orbit, so they are ahead of NASA in the particular race that has been uniting them for so long. Of course, at the moment, China has not tested cryogenic propellants, but tried hydrazine replenishment. There is still room for improvement. Write down the date. The mission will depart aboard an Electron rocket from Rocket Lab. The launch will be in the summer, no earlier than July 17, from New Zealand.

What they are, what frauds can reach you from unknown numbers and what you can do about it

by

Let’s explain to you What it is and what you can do about spam on WhatsAppdifferent types of fraudulent advertising and scams that can reach you from unknown numbers through this application. So, if we didn’t have enough with SMS spam, now it seems that it is also happening in this other application. This is a growing trendand we are going to start by telling you how this type of fraudulent messages work, so that you know the way of those who use them to send you spam or even online scams to steal your data. Then, we will tell you how you can try to combat these types of messages. How this type of messages works We have already become accustomed to receiving spam calls of various types, especially fraudulent calls. Obviously, our emails are also full of fraudulent messages, and it is common for there to be SMS fishing campaigns. Now, there is a new trend that is that these fraudulent messages reach us through WhatsApp. It is about messages we receive from unknown numbers. These messages have everything from fake job offers to fake messages from your supposed bank, to supposed family members with financial problems and more. The attackers’ idea is to communicate by an app that we consider something more personal like WhatsApp, and play with our feeling that if it is a message through this application it must be from someone who knows us. This greater credibility that we give to WhatsApp messages is what scammers use to try to make us fall into their traps. And how do they get our WhatsApp? Well, it’s simple, every year there are many massive leaks of service data, and these may include our phone number. They can also directly buy it from those typical half-unknown websites where you can register and give your number, and then they do business with their users’ data. Once scammers obtain phone numbers of hundreds of people, they begin to send massive WhatsApps. Same as SMS spam, but within the WhatsApp app, because your account there is linked to your phone number. What can you do about it? The best advice we can give you is do not give away your data happily to any application or web page. It is very tempting to register on unknown pages or applications that we come across from time to time, and also others where they may be doing a promotion or giveaway. Here, note that the more services you put your data into The more likely it is that these will end up being used for bad purposes. Therefore, try to reduce this habit of registering to sites as much as possible, and use common sense when registering on pages or applications, especially those less known. It is true that possibly by the time you read this you will have already registered on several sites, but that does not mean that you cannot try to decide to start taking better care of your data from now on. And for when data and account leaks are unintentional, I recommend that you change your passwords periodically. Thus, if your username and password are leaked from a web page, it will be easier for them to not be able to enter it and obtain other personal information about you or steal your account. And finally, the most important thing: never trust a WhatsApp that comes to you from an unknown number. Treat these messages like SMS or emails, never trust them because if a company does it, it is possibly a scam, and if it is someone who claims to be a person who knows you, try to ask them questions about various things that only you and that person can know.

How Much Protein You Really Need per Day and What Science Says About Supplements to Reach Your Goals

by

In the sports world there is a great debate about how much protein should be consumed daily in order to have a good result in the gym and for the muscles to grow. But the truth is that sometimes the figures you hear about the doses you need to take are very high, and that is why it is best to go to the official source where they tell us the most appropriate doses for each person. We are not all the same. The biggest mistake when talking about protein is thinking that there is a universal figure, since recommendations vary drastically depending on whether you spend the day sitting in front of the computer or if you strength train four days a week. This is why authorities have historically established a minimum protein intake to avoid health problems, and not to optimize performance or body composition. The general population. Here the WHO it’s pretty clear pointing out that the minimum protein that should be taken is 0.75-0.8 grams per kilo of weight per day. But we talk about “minimum” and that means that it is not necessarily optimal, and that is why other guides raise this range to 0.8-1 grams per kilo of weight, emphasizing the need to include a source of protein in each meal.
