We have detected a mysterious and very potent radio signal of a nearby galaxy. And its origin is a complete enigma

by

In March 2025, an energy pulse as powerful as the one that emits our Sun in several days hit the earth. It lasted just a few milliseconds, but its detection, and above all, the location of its origin, mark a before and after modern astronomy. Now a team from Northwestern University has managed to identify the origin of the fast radio gust (FRB) brighter ever registered. Although there are still many questions to answer. What is a fast radius gust. To understand the magnitude of this finding you must first know what we are talking about. The astronomers themselves describe THE FRB LIKE a cosmic lighthouse of immense power that ignites during a fraction of second In a vast and distant universe. These signals are incredibly energy and travel for millions of light years to reach the earth’s telescopes. Detect one of these bursts It is already an achievement. However, the real challenge is Respond to the origin of these bursts of energy. Until now, the frb that were repeated, which gave scientists multiple opportunities to triangulate the position, had been precisely located. Now they have done it with only one signal. A “photo” with unprecedented precision. The protagonist has been baptized as FRB 20250316A which was detected on March 16, 2025. To achieve this, it is where our current technological capacity enters. Thanks to a telescope network called Chime Outriggerastronomers were able to locate this burst of energy with an amazing accuracy of 13 parsecs, which is equivalent to 42 light years. If we move this measure to the universe itself, we could talk that they have been able to point out a specific house in an entire city seen from space. Something that marks preceding, is that the first time it is achieved for a burst that has apparently been a unique event. An origin that was almost empty. The address from where this signal came to a spiral galaxy called NGC 4141. At that time, all the great telescopes of the world, from the MMT in Arizona to him Keck in HawaiiThey turned to observe that little corner of the universe. Everyone tried to look for some explanation to this event, but what they found did not square them at all. And it is that in the exact place of the outbreak of this signal there is nothing. Not a supermagnnetic neutron star (a Magnetar), Neither a nebula, nor any continuous radio source. A very quiet neighborhood. When looking around the point that scientists had located, you could think that there would be something spectacular. But nothing is further from reality. It was seen that the signal could not come from another close place. Specifically, the formation of stars closest to the localized point is 190 Persecs away. In this way, the origin is located in a really quiet region of the universe. There have been no more repetitions of the event. Despite looking intensely for months, the signal has not reappeared. This is key. Many frb are “repeating”, emitting bursts sporadically. If it were, given its closeness and power, we should have detected weaker pulses. Statistical calculations are clear: the probability that it is a known repeater and we have only seen this bright pulse is very small (with a tension of more than 3.7σ, a very high level of certainty in physics). What could cause this signal. This combination of factors puts the main theories about the origin of FRB. The most accepted hypothesis is that they come from young magnetares, neutron stars with incredibly powerful magnetic fields. These objects are usually born in active star formation regions. The fact that FRB 20250316A is displaced from its “cradle” could mean that the Magnetar He is older of the one that is thought (between 200,000 and 3 million years) and has moved away. However, this clashes with the active life that is presupposed to these objects. The study also rules out other scenarios, such as outbreaks gamma rays Recent The “cleaning” of the environment and the lack of any residual glow in radio or X -rays do not fit with the models of cataclysms such as the Fusion of two neutron starsat least not immediately. The beginning of a new era. Beyond the enigma of the origin of this particular signal, this phenomenon marks a before and after in astrology. The capacity of the Chime/FRB system to locate unique events with this precision The field will revolutionize. It will no longer be necessary to wait for a source to be repeated to be able to study it in detail. Now, astronomers will be able to create a large -scale map of the environments of hundreds of FRB, allowing to compare the unique bursts and those that are repeated every so often. Perhaps in this way we discover that, after all, not all FRB are born from the same type of event. We may be facing two (or more) different phenomena that produce the same type of signal. The universe is plagued by mysteries. From how The stars were formed to him How the ‘big bang’ formedthey still have Many intrigues For our scientists. This makes every time there are more fronts in open -open astronomy And also the hardware field for put our best teams pointing to space with the aim of increasing our knowledge.

The hidden reason why Elon Musk Lanza Satellites of Archienemigos like Jeff Bezos: The radio spectrum

by

On Monday morning, Spacex completed its 100th launch so far this year. But aboard the Falcon 9 rocket there were no new Starlink satellites, but a lot of 24 competition satellites. How have we reached a point where Elon Musk and Jeff Bezos, rivals on so many fronts, collaborate in space? A little context. Starlink has been growing without opposition for six years. At this time, Spacex has deployed More than 8,000 satellitesconsolidating an almost absolute domain of the satellite broadband Internet market. Now, a competitor with a comparable financial muscle has entered the scene: the Amazon Kuiper Project. The company founded by Jeff Bezos has begun to display its own megaconstellation to offer high -speed connections worldwide and compete directly with the Elon Musk service. Time against. The main challenge for Kuiper is time. The license granted by the Federal Communications Commission (FCC) of the United States requires him to have half of his constellation in orbit (that is, 1,618 satellites of a total of 3,232) before July 2026. Unlike Spacex, which has a complete vertical integration, Amazon does not manufacture its own rockets. To fulfill the deadline, the technological giant made in 2022 the “greater commercial acquisition of history of history”, signing contracts with ULA to use its atlas V and Vulcan rockets, with Arianespace to use the European rocket Ariane 6, and with Blue Origin, the aerospace company of Jeff Bezos himself, to use the gigantic new Glenn rocket. The problem is that most of these pitchers are new and have suffered important delays. They are just business. Although Bezos tried to prevent Amazon from using Spacex services, the most honest option with shareholders was to hire several Falcon 9 rockets, which thanks to their unique reuse capacity usually offer the lower price per kilogram Put in orbit. Spacex has already shown that he is willing to launch satellites of his competitors. Between 2022 and 2024 he launched four lots of satellites for Eutelsat Oneweb, his European rival, after the Russian invasion of Ukraine took the Soyuz and proton rolling from the market. For Spacex, this is a round business because the money of its competitors is pocketed, which can reinvest in its own satellite constellation. But there is another reason. A strategic issue that goes beyond the launch business. The coin of covert change is the increasingly saturated radio spectrum. According to one Wall Street Journal ResearchSpacex has used its dominant position in the release market to press its rivals and obtain a crucial advantage for Starlink: spectrum rights. The radio spectrum is the electromagnetic wave set that are used for wireless communications. It is a resource finite, invisible and absolutely essential so that satellite constellations can send and receive data without interference. Governments around the world, through organizations such as FCC in the United States, are responsible for assigning rights to use it. Spacex needs more spectrum. And he needs it desperately to be able to serve the More than four million Starlink users As it continues to expand. According to the Journal, Musk’s company would have asked companies such as Oneweb and Kepler Communications to give him part of his spectrum rights as a condition for launching his satellites. Although Spacex denies it, the report details how Oneweb, after running out of the Russian rockets, reached an agreement with Spacex that included “spectrum concessions” to ensure the releases it needed. Elon Musk’s web. This strategy places Spacex competitors in an incredibly difficult situation. It is a dilemma that the analyst Tim Farrar Describe as “Carefully choose”. Companies such as Echostar or GlobalStar have had to decide between going through the Spacex ring, giving competitive advantages, or paying more for slower access to space with other rocket companies. If there are. Ast Spacemobile, who had opted for the New Glenn rocket of Blue Origin, found that Bezos’s rocket would not be ready on time And their satellites, much heavier than expected, will have to wait. Apple’s case. In 2022, Musk I had offered Apple exclusive access to Spacex For 5,000 million dollars, an offer that Apple rejected. Apple ended up closing an agreement with GlobalStar for its satellite emergency service, but later, the delay in the launch of GlobalStar’s satellites by Spacex seems to have benefited Starlink. The explanation of the delay and renegotiation of the launch contract seem to have to do with that Apple will end up reaching an agreement To offer Starlink Direct-to-Cell on the iPhone 13, a model that is not compatible with the GlobalStar service. This gave Starlink an advantage in the race for the cell connection at a time when Apple already debated internally if he could compete with the rhythm of Spacex. The giant Starlink. In the end, each launch of a competition or agreement satellite by the spectrum becomes a tactical victory for Elon Musk. Not only does it charge for the service, reinforcing the finances of a company whose income They are about to overcome NASA’s budgetbut it uses its domain to ensure the most vital resource for the future of global communications.

An object never seen on the Milky Way is emitting radio waves with X -rays exactly every 44 minutes

by

The Milky Way continues to present new mysteries through the telescope. An international astronomer team has discovered an objectuntil now unknown, which emits powerful radio bursts with a watchmaker’s precision. But the strangest thing is that we know that they are accompanied by X -rays. Context. One of the cosmic fashion phenomena in astronomy magazines are transitory long -period radio objects (LPRT), whose understanding is still in diapers. Since 2022 only 10 have been identified, which were overlooked or confused with other celestial objects. LPRT emit bursts of radio waves periodically, but with much longer intervals (of minutes or hours) than traditional pulsaries, which usually have periods of second or milliseconds. The progress in radio telescopes has opened a window to the transitory universe that allows astronomers to identify LPRTS more easily. One of the most powerful radio telescopes is the Australian Matrix Askap, which consists of 36 parabolic antennas 12 meters in diameter acting as a single instrument of 4,000 square meters. Double surprise. Astronomers have just added a new layer of complexity to the world of LPRTS with the discovery of Askap J1832-0911, an object that emits powerful radio wave explosions. Your pulses last two minutes and repeat every 44 minutes and 12 seconds. The finding is important because it is just the tenth LPRT discovered and places the new object among the 30 most brilliant radio sources in the sky. But the surprise came to cross the data with observations of the NASA X -ray Space Telescope. Chandra had observed the same area of ​​the night sky at the same time as Askap (what scientists have compared with “finding a needle in a haystack”). The Observatory discovered X -ray emissions from the same point and with the same cycle of 44 minutes and 12 seconds. It is the first time that an LPRT emitting waves of both frequencies. Collapsed lines. ASKAP J1832-0911 is around 15,000 light years from Earth, in a very populated region of our galaxy. This location greatly hinders its study in other wavelengths, because there are many objects that could be obscuring it, and an immense amount of dust that blocks our line of vision. Infrared searches have also not yielded results, although hope is put into future observations with the James Webb space telescope. Unlike other LPRTS that seem to “light” and “turn off” intermittently, the object has been active during the 10 months that observation has lasted, although with a variable brightness. The million dollar question. What exactly is Askap J1832-0911? There are many theories about what type of object could be producing such regular and energy signs. This object is different from everything we have seen before, but researchers do not believe it is an extraterrestrial civilization sending messages because the emission spectra are too broad. Instead, two main suspects shuffle. The first is an old magnetar: a neutron star with incredibly powerful magnetic fields in his last stage of life, possibly orbited by another star. The second is an ultra -freeized white dwarf: the remnant of a low -dough star at the end of its evolution, with an exceptionally strong magnetic field and a companion star. But for this theory to fit, the white dwarf would need the most intense magnetic field ever detected in one of its class, surpassing the 5 × 109 gauss. We know nothing. “Finding such an object suggests the existence of many more”, Nanda Rea saysCo-author of the study and professor of the Institute of Space Sciences (ICE-CSIC) in Spain. “The discovery of its X -ray transitory emission opens new perspectives on its mysterious nature.” This discovery not only adds a new mystery to the list of things that we do not understand the universe. He also suggests that LPRTS, of which we barely know 10, are more energy than was thought. Hunting to find more objects like this and decipher its origin has only begun. Image | POT

How Radio María has silently won a community of millions of faithful

by

Radio María is one of the most important radio phenomena in Spain. With a community of listeners that are counted by millions worldwide, its history is not exempt from controversies. However, when the entire country succumbed to last week’s blackoutRadio María endured firmly without interrupting its programming. This is how this unique dissemination chain of Catholic thought works. Stop Radio María. He Past black that left the whole country disconnected did not affect all radio stationswhich made the little and old -fashioned transistors In very precious goods. Among the chains that endured the envy with, among other means, electricity generators such as Those of HospitalsThey were RNE, Zero Onda, La Cope wave BE. But among all, Radio María highlighted for its apparent modesty: indefatigable, it was still arriving at all points in Spain thanks to its large number of repeaters, 2,000 worldwide. A figure comparable to that of any large radio chain. Maria for the world. The devotees of the station will not be surprised: Radio Maríaof Italian origin, it is heard in points of Spain where the rest of the chains, even the big ones, arrive with difficulty, thanks to the 225 stations that have distributed throughout the country. And even beyond: it has 93 radio stations in the world, reaching points as remote as Asia or Oceania, which add 11 stations. Radio María presumes 500 million listeners (potential) that are sustained thanks to a network of volunteers that make possible the propagation of the radio faith: since 1998, since 1998, World Family of Radio Maria It is a non -profit association that brings together all these stations. A radio consecrated to faith. Radio María was born in Italy in 1983, as a parish radio in the diocese. Safe and priests wanted to develop an evangelization work with explicitly religious programming. This has been respected in radio growth throughout the world, and is noticed in its Spanish incarnation, where it arrived in 1999. On its grill the religious dissemination programs with all the spasible approaches (Jívenes, elders, marriages, psychology, theology, sacral music, news related to the Pope and the Church) and, of course, the religious acts, with prayer programs and two daily masses. Armando Lío. One of the aspects that Radio María takes care of is its relationship with younger Catholics. It has a program, in fact, entitled “Armando Lío”, such as Hakuna’s slogan, the Youth Catholic Activism Association that He congregated 85,000 people in Cibeles chanting their religious pop hymns. Although Radio María is little given to facilitate audience figures for its programs, the attention on their grill to spaces oriented to the youngest public, such as’Armando Lío‘,’Breaking molds‘Or also musical’Sing and walk‘They are proof that generating a community that supports the project is an important objective for the survival of the station. Niche community. Radio María is the perfect example of how beyond the attention of the great media and the general public live very numerous and involved communities, to the point of sustaining one of the most effective and listened radio stations of the country only with donations. “Our goal is to reach everywhere and we act to achieve it. It may sound very rare, but we do not move for the number of possible listeners or the possibilities of a station, we have some principles different from those of conventional radio,” said Quintanilla in the confidential. Undoubtedly, a criterion that has led the station to highlight in a situation as adverse as a national blackout. How is financed. It is the big question, the great enigma around Radio María. Officially, the station makes it very clear on its website: Maintaining the issuance costs 573 euros at the time, and the options for the faithful are multiple: periodic or punctual donations, income and transfers, checks, bizums .. until the fiscal deductions that correspond by donations are specified, which make up the 99% of the issuing income. The other leg of support to Radio María is the network volunteerwhich also admits multiple variants: in the promotion, in the dioceses, from home … Currently, they have more than 1,500 volunteers throughout Spain, which generate 90% of the programming. However, doubts also arise. Recent doubts. Of course, not everything is very clear accounts: yesterday The Superior Court of Justice of Castilla y León annulled the order by which the Board had awarded 124 radio licenses, 27 of them to Radio María. One of the reasons for the complaint, filed by the being, is that the stations were awarded irregularly: both Radio María and another of the main beneficiaries, the eleventh hour (owned by the Adventist Church), are non -profit stations and the bases of the Award Contest spoke of “provision of commercial audiovisual services.” Radio María and the eleventh hour monopolized 30% of the licenses awarded. Everywhere. Diffusion strategies like this or how to buy Rodrigo Rato in 2012 six radio licenses For a million euros They assured him total coverage in the Balearic Islands are those that have guaranteed his brutal expansion. Although its president, José Manuel Díez Quintanilla, affirms that certain activities that root the illegality They are a thing of the pastRadio María has taken advantage of its non -commercial condition to invade foreign frequencies or expand power above what was allowed, which earned them in their day the occasional fine like one of 126,000 euros from the Junta de Andalucía In 2012.

There was a time when even the shampoos or the Pokéball had a radio. And Spain has rediscovered by force

by

The blackout that Spain suffered Last Monday, April 28, with still unknown causeleft a very learning: The radio It was by far the best means to inform yourself Before the crisis. The stations survived the cuts thanks to electrogen equipment and the spotlights of the Spaniards allowed to be aware of the situation. During the hours after the blackout, Tiktok became a stranger transistor showcase. The Radio-Ranathe radio-barbieradios that They emulate those of past centuries… Spanish being Spanish, as we usually do The golden age of the transistor. Between the mid -50s and the end of the 80s the radio became a key medium thanks to the transistor. A cheap electronic device, small and easy to implement in any device. The radio was The most immediate medium To know the news, and the big companies began to obsess with providing this technology to their products. The solution was easy: turn your objects into radios. A cultural phenomenon. Having a radio at home was part of pop culture and was synonymous with modernity, a train to which the big (mainly American) began to join from the 60s. They began to integrate radios into watches, briefcases, coca-cool bottles, hair dryers, backpacks … and even shampoo boats. The radio became more a claim than a real utility with the popularization of TV and the Internet entered the 90s. The most rocambolesque radios. The blackout has left us dozens of videos and memes related to the most hilarious transistors. Some that demonstrate the fever in Spain with these products and, particularly, the resistance to the time they have. An HS shampoo, an informative Pokéball, or the Pizza Hut radius in collaboration with Cocacola for 25 years ago that my partner Rubén had in the drawer. Immune devices to programmed obsolescence and with the only need for a few AA batteries to function. A profitable market. Rescue HS shampoo It has a price of 75 euros on eBay. A Darth Vader head with Radio exceeds 100and a mini Coca-Cola fridge with radio included It costs about 30 euros. The radio culture, lives more than 100 years after its invention, has been the best evidence that Current technology is not infallible, And that there are inventions that far from being obsolete, have not yet been overcome.

This Xiaomi tablet would have come from pearls during the blackout. It is one of the few Android models with FM radio

by

FM radio is something we don’t usually see on Android devicesbut that they had come from pearls during the Mass blackout A couple of days ago – I itself have no radio at home, so they would have come phenomenal. Nevertheless, Although it is not usual, there are a few exceptions. Xiaomi Redmi Pad Se 8.7 (128 GB) * Some price may have changed from the last review The redmi pad is 8.7 is one of the few Android devices with FM radio There are currently some mobile phones that come with Radio FM, but if we also want to be an Android device … the thing is complicated. Xiaomi is one of the few exceptions, and that is that in the technical file of his tablet Redmi Pad SE 8.7 We can see that it comes with FM radio. It is something unusual, but what At times like those of the blackout, it is appreciated. If you are interested, it is a cheap tablet, since its price is currently 99.99 euros In the official store. Obviously, one radio We can be more useful if it works in batteries, but it is still curious and that we can take advantage of if we have the Xiaomi tablet. Most devices where we find radio FM reside in basic mobilesthat They get closer to the mobiles of yesteryear than to the current. A good example is the Nokia 106whose battery also has a great autonomy of approximately 15 hours. And can be found for sale in stores like Amazon at a price of 21.47 euros.

The blackout in Spain has demonstrated which is the ideal means to inform in a crisis: the radio

by

In the minutes that followed the Broady in Spain and Portugal At 12:32 yesterday, millions of people They wondered The same: “What happened.” In other crises, television, newspapers and of course the Internet are the clear alternatives to find out what is happening, but yesterday that was not possible. Almost everything failed, but there was a means of communication that allowed us to keep us informed: the radio. Where is the FM radio of the mobiles. The fragility of our communications caused the radio to erect as a unique solution to keep us informed. The mobiles had support for FM radio years, but this feature has disappeared in all current models. In fact It went from being an extra desired to an exclusive function of cheaper models. Something older mobiles do have that function by connecting headphones (which bend as antenna), and that allowed those who still have any of those mobiles could be informed thanks to that functionat least while the mobile battery lasted. Some brands keep them in some models. Xiaomi is one of the manufacturers that still includes support for FM radio in some of its Redmi family models, but of course not all. He Xiaomi Redmi Note 14s or the Redmi 14c They are good examples. The normal thing is that in recent terminals we will not find that option, which we can enable in older mobiles (such as Little m5he Motorola G73 5g or the Samsung Galaxy M23 5g) and also in input range terminals and in less extended brands such as Doogee or Ulefone. Radio as informative lifeguards. Without light there was no television or wifi in houses and offices, and connect to the Internet It was an odyssey all day: Mobile lines, the only ones that could give a way out, worked irregularly … If they worked. And yet, the radio worked without apparent problems. Transistor to batteries. Meanwhile, those still kept a battery transistor at home could be informed thanks to the radio stations continued to broadcast during the blackout. These transistors became the salvation of many citizens, who either had radios in their homes or gathered in the streets around vehicles with analog radios or that could listen to the radio What other people had in the streets or on the terraces. They were also one of the products that They sold out more quickly in shops that remained active during the blackout. Why the stations continued to work. Augusto Molina and Héctor Zafra are respectively the technical director and the technical manager of the SER, and explained In a piece in this medium The way of proceeding in these emergency cases. The first thing they did was turn off monitors and all the teams that could be turned off to save to the fullest. That allowed maximizing the autonomy of emergency equipment that is used in these cases, and that were the key both in the SER chain and other stations. Electrogen equipment. These structure (motorogener) groups are machines that generate electricity through an internal combustion engine. They make use of fossil fuels (gasoline, diesel) and allow generating electricity while the fuel lasts. Are the teams that They are used in hospitals to maintain a good part of the essential services during this type of energy crisis. Several stations survived the blackout. National Radio of Spain kept for example emissions, such as They also did wave zero, the Cope chainthe aforementioned chain and other stations – although not all – and broadcasters who could continue to inform thanks to those emergency teams that were activated during the blackout. Radio as lifeguard in emergency situations. What happened yesterday has revealed the relevance of the radio as an ideal means of communication to emergencies. There have been numerous cases in the story in which that has become evident. In our country they stand out for example The coup d’etat of 23-F In Spain, in 11m or more recent attacks The Dana that ravaged the Valencian Community and that caused the majority of the electric laying. Transistors, both in one and another, allowed to remain informed.

In full nervousness for the cutting of submarine cables, China has a final weapon: a radio in steroids

by

The Submarine cables They are one of the most important elements today. Not only is it a huge infrastructure that organizations and companies continue to develop -with such ambitious projects as the Meta cablewhich will take more than one return to the earth-but have become today thanks to the Ukraine War already maneuvers at the South China Sea. It is in this conflict that Some cut cables They have triggered the fear of running out of the Internet, and everything that implies. These cables are protected, but can be damaged by ships. Now, China has presented a device designed with a task in mind: cut underwater cables. And it is the first time that someone announces that he has a tool capable of interrupting critical underwater networks. The importance of cables. There are more than 1.4 billion meters of submarine cables that connect all countries. There are other thousands of kilometers planned, and the vast majority of communications in some countries depend on these cables. 95% of them in the case of Australiafor example, and I know esteem that 95% of the data managed by the American population and 75% by China depend on them. They are vital for the Internet and all that this implies, such as streaming, artificial intelligence or servers, and this year they have become protagonists in war scenarios. Countries in conflict have realized that they can cause great damage by cutting these cables by boats or through more sophisticated techniques, such as Sound attacks. There are times that They are simple accidentsbut the suspicion that a damaged underwater cable corresponds to an enemy attack is something that is there. And more now with what they just announced from China. The Chinese device. As we read in South China Morning Postthe State Key Laboratory of Deep Water Crewing Vehicles and the Scientific Research Center of Ships of China, have developed a tool that describe as “compact” and that is capable of cutting the most sophisticated underwater communication lines or energy in the world. As it is a tool designed specifically for this, it has been conceived to cut cables at depths of up to 4,000 meters. There are no cables right now that they are in such depth, but its creators have provided the device with a completely sealed titanium alloy housing to resist that enormous pressure. This is Haidu, and can carry this “radial” Your weapons. The device is equipped with a kilowatt engine and as a cutting tool uses a 150 millimeter diamond wheel that rotates at 1,600 revolutions per minute. Let’s say it is the mixture between a protected drone to endure very high pressures and a radial. This cutting tool allows to destroy up to armored cables that have steel layers, rubber and polymeric coating. And its form has been designed so that it can be integrated both in manned and non -manned submersibles of China. For example, haidou vehicles or Fondouzhe could have this as one of their tools. He Haiduas a curiosity, it is an unmanned submersible in the form of fish and eyes drawings and fins created for exploration. He Fendouzhe It is a manned submarine, also for research and exploration. World Order. As we say, threaten to cut underwater cables It is not something new. We have seen it in the Ukraine War, but it is the first time that a country officially reveals a tool designed exclusively for that task. Of course, those responsible affirm that the tool has been created for civil purposes. Which is it? Rescue and mining operations in the maritime bed, but it is evident that it is a tool that is surely causing the other neck itching in rulers around the world. It is clear that such a tool can destabilize communications in a crisis and be used strategically during an attack. And it is not only communication, but everything that has to do with the Internet, such as servers and services that depend on them. Debate and consequences. When a cable is cut, communications are rapidly redirected through another, since they are prepared to have a large bandwidth. Therefore, important interruptions are not usually produced, but that cable You have to repair itbeing a fairly expensive process. Now, when it is not a single cut cable, but several, that connection may be set. It is what has led to a debate about the need to protect infrastructure. NATO has launched The mission “Baltic Sentry” To patrol sensitive regions with airplanes, drones and warships. There are also companies that are offering advanced cable monitoring services, answering all measures to a single issue: the protection of infrastructure and early detection to prevent cuts. That there are countries that have already made public that have sophisticated tools for cutting submarine cables and interfering with world geopolitics, is a new headache.
