Japan has discovered rare earth tons on its most remote island. Casually, a Chinese aircraft carrier has just approached

by

Year 2022. Japan Make a decision That he was going to be fruit months later. The Japanese nation did not want to depend so much on China in a matter of rare earths, so decides to start a series of projects to search for them even at the bottom of the ocean. In the summer of 2024 they give a treasure in that seabed: a site of 230 million tons Of those “precious” lands, a swag that are under the easternmost island of the nation. Chance or not, something unprecedented has just happened in front of the enclave: a Chinese fleet With an aircraft carrier. An unpublished maneuver. For the first timea combat group headed by the Chinese liaoning carriers He has entered the exclusive economic zone (ZEE) of Japan, marking a new phase in Beijing’s naval projection and awakening immediate concern In Tokyo and Washington. The group, composed of the aircraft carriers, two destroyers with guided missiles and a supply ship, penetrated waters to about 300 kilometers to the southwest of the Japanese Minamitori Islandthe easternmost point of the archipelago, before leaving the area to perform aircraft takeoff and landing exercises. Although Japan He avoided confirming If he presented a formal protest, he said he had transmitted an “appropriate” message to the Chinese authorities: he displayed the Haguro destroyer To follow the activity of the Naval Group. Minamitori and his treasures. As We explained at the beginningthe incident is not just symbolic: Minamitori It is not inhabited by civilians, but houses facilities of the Japanese weather agency, self -defense forces and coastguards. Beyond its isolation (about 1,900 km from Tokyo), this remote island has become a point of Geoeconomic interest Due to the vast submarine deposits of rare metals, especially manganese nodules. In fact, recent studies estimate that nearby seabed contain More than 200 million of tons of these resources, fundamental to Strategic technologies and high capacity batteries. The passage of Liaoning so close to the enclave adds a warning dimension on Chinese interest not only territorial, but also economic in areas where Japanese sovereignty is not in dispute. Minamitori Island Leave Vú. Although this has been the first documented incursion of a Chinese aircraft carrier in this part of the Japanese ZEE, the truth is that it is not An isolated fact. Liaoning himself had already sailed Last month Between two Japanese southern islands, also within another region of the Japanese ZEE. In September 2024, he crossed between Yonaguni and Iriomote, two islands near Taiwan, even entering into adjacent watersthat extend to 24 nautical miles from their coast. In each of these movements, Beijing has rehearsed navigation patterns that expand the operational scope of its navy, reinforcing its ability to operate far from its coastline and projecting power in sensitive areas. Tactical climbing. We have gone counting. These incursions occur in a context of Regional tensions persistent. Japan and China keep years ago A dispute over the Senkaku Islands (Diaoyu in Chinese), uninhabited, but strategically located in the Eastern China Sea. Beijing has not stopped pressing its claim with regular naval patrols (even with buoys), while strengthening its presence in the Western Pacific through demonstrations of force such as Liaoning. The repetition of these maneuvers suggests A deliberate campaign to expand the regional tolerance threshold in the Chinese presence in areas traditionally dominated by the United States and its allies. Contained response. The spokesman for the Japanese Ministry of Defense has been clear when interpreting the maneuver as An effort from China For “improving its operational capacity in distant areas”, a reading that coincides with the recent evolution of Chinese military doctrine, more ambitious and less disguised. Although Tokyo has opted for a rather mesurated response, focused on intensive surveillance instead of direct confrontation, the underlying message It seems unequivocal: Japan is not willing to normalize Chinese military traffic in its maritime influence areas, especially in areas close to resources strategic However, the lack of a formal diplomatic protest could be interpreted as an attempt to avoid an immediate escalation while alliances are consolidated and countermeasures are evaluated. A red line. What just a few years ago would have been unthinkable, that a Chinese combat fleet with an aircraft carrier would navigate so close to the Japanese eastern end, today is an operational reality with lasting implications. As China strengthens its fleet and displays your assets With greater confidence, the Pacific maritime border becomes a board increasingly unstablewhere the strategy of the consummate threatens with redefining the rules of the game. If you want also, the Liaoning transit Together with the Japanese island, not only defies the regional balance, but also rehearses the normalization of a Chinese military presence in key areas for the energy, territorial and technological security of Japan.

China considers softening its rare earth blocking, although not for everyone. It is great news for Europe

On April 4, just 24 hours after Donald Trump announced the taxes that he was going to apply to the importation of most products from abroad, The administration led by Xi Jinping responded. And he did it with forcefulness. In early December 2024 He chose to prohibit The export of some critical minerals to the US, among which were three essential metals for the chips industry: Gallium, Germanio and Antimony. Shortly after the Chinese government added two more critical metals to its list of export restrictions: Scandio and Disposio. These chemical elements are probably less known than metals prohibited by China previously, such as Gallium or Germanio, but are at least as important as the latter because they have a fundamental role in the industries of integrated circuits, telecommunications and the manufacture of storage devices. China has Europe at its feet The ability to put pressure from China had not yet been extinguished. Just ten days later, on April 14, the Administration did not hesitate take another step forward With the purpose of putting in check, in addition to the industries that I just mentioned, those of electric cars, aeronautics and advanced armament. To achieve this, it effectively suspended, in addition to the export of the most valuable rare earths, that of high -power magnets that have a critical role in the industries that I have cited in this same paragraph. China’s export controls are mainly directed to the US, but the old continent does not remain unscathed Chinese authorities are retaining in ports throughout the country not only rare earths, but also high -power magnets acquired by electric cars manufacturers throughout the planet, aerospace companies, chip factories and armament companies. Many of these organizations have high -power magnet reservations made with rare earths, but possibly They will only allow them to subsist a few months. Europe in particular is in an extremely delicate position. China’s export controls are directed mainly to the US, but the old continent It does not remain unscathed. At least for the moment. In fact, in Germany, which as we all know is the heart of the European car industry, There are already experts who assure that if China continues to retain rare earths and electric motors some essential parts of the electric cars production chain They will stop in no more than six weeks. For the European car industry this blow would be very difficult to fit. European companies that are dedicated to the manufacture of semiconductors are also in a very compromised situation. According to Reuters Many European chip production lines They will stop very soon Due to the shortage of crucial supplies, which has led the European Chamber of Commerce to meet with officials of the Ministry of Commerce of China to ask them to allow rare earth supply to European companies that are dedicated to the production of integrated circuits. The result of this meeting has not yet been officially completed, but the information that has been leaked maintains that China is willing to relax its export controls for some European companies.

China is drowning rare earth supply and in six weeks there will be a victim: European electric cars

China has completely stopped The export of rare criticisms. In fact, during the last year and a half this Asian country has used its dominance over rare earths as A pressure tool on your rivals. On December 21, 2023, the administration led by Xi Jinping decided to restrict the export of some of its rare earth processing technologies, and this was only the tip of the iceberg. The last kick linked to these important metals was given by China to the US on April 4. Just 24 hours after Donald Trump announced the taxes that he was going to apply to the importation of most products from abroad, the administration led by Xi Jinping replied. And he did it with forcefulness. In early December 2024 He chose to prohibit The export of some critical minerals to the US, among which were three essential metals: gallium, Germanio and antimony. The European electric car can suffer if China continues with the hand brake This story does not end here. At the beginning of last April the Chinese government added two more critical metals to its list of export restrictions: Scandio and Disposio. These chemical elements are probably less known than metals prohibited by China previously, such as Gallium or Germanio, but are at least as important as the latter because they have a fundamental role in the industries of integrated circuits, telecommunications and the manufacture of storage devices. And just two weeks later, in mid -April, the administration led by Xi Jinping did not hesitate to take another step forward with the purpose of putting in check, in addition to the industries that I just mentioned, those of electric cars, aeronautics and advanced armament. And is that, according to The New York Times, has effectively suspendedin addition to the export of the most valuable rare earths, that of the elements involved in the manufacture of high -power magnets that have a critical role in the industries that I have cited in this same paragraph. Chinese authorities are taking the high -power magnets acquired by electric cars manufacturers throughout the country Chinese authorities are retaining in ports throughout the country not only rare earths, but also high -power magnets acquired by electric cars manufacturers throughout the planet, aerospace companies, chip factories and armament companies. Many of these organizations have high -power magnet reserves made with rare earths, but possibly only allow them to subsist a few months. For many years China has produced More than 90% of rare earths. Australia, Vietnam, Myanmar, Canada, Brazil, Tanzania or the US, among other countries, also produce these metals, but the largest deposits located so far of these elements reside in China. And, curiously, the country led by Xi Jinping too The processing industry dominates to which it is necessary to submit rare earth so that they can be used. So much so that its quota if we stick to the global processing industry amounts to 90%. China’s export controls are directed mainly to the US, but Europe is not unscathed. At least for the moment. In fact, in Germany, which as we all know is the heart of the European car industry, There are already experts who assure that if China continues to retain rare earths and electric motors some essential parts of the electric cars production chain They will stop in no more than six weeks. For the European car industry this blow would be very difficult to fit. However, while still having some reservations Europe has the opportunity to negotiate with China to avoid this very difficult situation. Everything is not lost yet.

The bad news is that the oxygen of the Earth has an expiration date. The good is that we will not be here to see it

by

We can breathe calm. Also the grandchildren of our grandchildren’s grandchildren. But the oxygen that supports complex life on Earth will not be eternal. Our oxygen -rich atmosphere has approximately one billion years. So, the change will be drastic. A rapid dexygenation. An international study published in Nature Geoscience Details the calculations. After making more than 400,000 simulations on the geological and biological evolution of our planet, Japanese and American scientists came to the conclusion that the Earth will experience rapid dexygenation that will return it to an atmospheric state similar to that of the archaic land of about 2.5 billion years ago. What the sun gives you, the sun takes it away. Until recently, the scientific community estimated the life expectancy of the Earth’s biosphere in another 2,000 million years, when global warming at geological time scales leads to the evaporation of the oceans. But this new model projects a different scenario. According to researchers, the increase in solar radiation will intensify the cycle of carbonates and silicates. This will cause a drastic decrease in carbon dioxide concentrations. With less co₂, photosynthetic organisms such as plants, the main oxygen producers, will die. The result: a vertiginous fall of atmospheric oxygen. If perhaps, anaerobic life will remain. With a millionth of the oxygen we have today, complex life forms will be extinguished long before the oceans boil and the planet is left without surface water. For the vast majority of life forms, whose metabolism depends on oxygen, this will be the end of the road. The model indicates that deoxygenation It will happen at 1,080 million years (with a deviation of ± 140 million years). By then, the earth’s atmosphere will be radically different, with high levels of methane, low carbon dioxide levels, and a total absence of ozone layer. With luck, it will be a world of anaerobic life forms. And what is this data for us. Although we will not affect us, nor the grandchildren of our grandchildren’s grandchildren, the study, funded by the Nexus for Exoplanet System Science Science project of NASA, has important implications for the search for extraterrestrial life. It suggests that an oxygenated atmosphere is not a permanent characteristic of habitable worlds. Oxygen, and its photochemical by -product, ozone, are two of the biofirms that seek space agencies in exoplanets. If the oxygen rich atmosphere of the Earth will last between 20 and 30% of the total life of the planet, other planets similar to the Earth could now have weakly oxygenated or anxic atmospheres. The search for life beyond our solar system will have to expand its scope to other biological firms.

The last time all humans were on earth

by

It sounds like the beginning of a science fiction work, but it is a silent milestone in the history of our species. On Tuesday, October 31, 2000 marked the last day in which every human being of the planet was on this side of the atmosphere. Since then, there has not been a single moment in which full humanity has been confined to our native planet. A historical launch. That October 31, 2000, A Soyuz ship took off from the Baikonur cosmodromein Kazakhstan, carrying on board the expedition 1 of the International Space Station: the American commander Bill Shepherd of the NASA and the Russian cosmonauts Sergei Krikalev and Yuri Gidzenko de Roscosmos. The crew reached an incipient ISS on November 2, 2000. It barely had a couple of modules (the Russian Zarya and the American Unity, assembled in 1998), But since then, the orbital laboratory has been occupied uninterruptedly. For 24 and a half years, there is always some human floating about 400 kilometers on our heads. A quarter of a century. The International Space Station is a collaborative project between five space agencies (the American Nasa, the Russian Roscosmos, the European ESA, the Japanese Jaxa and the Canadian CSA). It is not only an international cooperation symbol, but an unparalleled scientific laboratory, that orbits the land every 90 minutes at a speed of almost 28,000 km/h. In this quarter of a century, the orbital station has reached a habitable volume greater than that of a six -bedroom house, with A 109 meter wingspan and an average of seven people always on board. It can attach up to eight spacecraft simultaneously and has hosted almost 3,000 investigations of more than 108 countries, taking advantage of microgravity to study from particle physics to the effects of space trips on the human body. The ISS gives the witness. Aged and with age of agelike the air leaks that bring their operators head, the ISS members plan to leave it in 2030, before A ship developed by Spacex The towing to a safe place for its atmospheric reentry. NASA’s strategy is clear: ceasing to be the owner and main operator to become a key client, thus ensuring the continuous human presence in the low terrestrial orbit. This will allow to continue investigating in microgravity (which is crucial for future missions to the moon and Mars), maintain international collaboration and promote a commercial space economy. USA It has just reduced the budget for ISS hoping that there is a rapid transition to the new commercial stations. Companies such as Axiom Space (with their Axiom Sation project), Blue Origin (With your Reef orbital) or Voyager Space (With Starlab, in collaboration with Airbus) They are developing new private orbital platforms. What if they are not ready in time? If commercial stations do not arrive by 2030, humanity will continue to inhabit the orbit low thanks to China. Vetada de la ISS, China has expanded its presence in space With the Tiangong Space Stationcontinuously inhabited since 2022. China not only plans to double its size of three to six modules in the coming years, but is already opening its doors to international cooperation, as demonstrated by the recent agreement for Train and send Pakistani astronauts To the Chinese Space Station. With NASA focusing on a commercial model and the exploration of deep space, Beijing is strategically positioned as a central actor and a possible alternative in the low orbit, especially for nations that seek to collaborate outside the US frame. A changing environment. But there is another reason why the United States has focused on the moon and Mars. The low terrestrial orbit faces the increasingly critical challenge of space garbage. Millions of objects, from dead satellites and higher stages of rockets to small undetectable fragments generated by collisions or antisatellite missile tests. These waste travels at huge speeds and represents a risk of collision constantly and potentially catastrophic for astronauts. ISS itself has had to perform numerous evasive maneuvers in recent years. Manage this problem through better follow -up systems (especially for small objects), the active withdrawal of the most dangerous waste and, above all, prevention and mitigation in the generation of new space garbage (such as rapid exorbitation of rocket stages) will be essential to guarantee the safety of future long -term crew. For now, and for almost 25 years, we continue to live the space. On October 31, 2000, it was the last day of an era in which humanity was anchored exclusively to Earth. Since then we have been, uninterrupted, a species with extraterrestrial presence. Human permanence outside the earth seems assured, but its sustainability will require even more global effort and cooperation.

There is an old Soviet probe about to fall on earth. The disturbing thing is that it was designed to resist hell

by

A piece of Soviet spatial history, the Kosmos 482 probe, is about to conclude its very long 53 -year -old odyssey. And in the most disturbing way possible: falling on us. Context. Launched on March 31, 1972, this Soviet ship was destined Venus, but A failure after its launch left it stranded In the Earth’s orbit. 53 years later, its final decrease is imminent: it is expected to be re -entered into the atmosphere around May 10. The probe does not contain nuclear materials, and the risk of properties or people is low … but it is not null. And you don’t want an object of half a ton that falls from the sky to hit you. Kosmos 482. Twin sister of the successful Venera 8 mission, she was launched only four days later, but unlike the first, she failed to land in Venus. The upper Blok-Nvl stage of the Molniya rocket that transported the Kosmos 482 went out prematurely, leaving the probe trapped in a very high elliptical terrestrial orbit (initially 206 x 9,800 km high). Faithful to the secretism of the time, The Soviet Union never admitted the ruling And he simply baptized the mission with the generic designation “Kosmos 482”. After three days, several fragments that had separated from the ship rented over New Zealand, where some remains were even recovered, such as cylindrical fuel deposits. Other objects associated with the mission rented in 1981 and 1983. Designed for Venusian hell. The object that has resisted all this time is the mission descent capsule, aimed at landing in Venus. It is estimated that this sphere has an approximate diameter of one meter and a mass of about 500 kilograms. Here comes the interesting thing: this capsule was designed to survive the infernal atmosphere of Venus, a planet whose average temperature on the surface is 464 ° C. As he points out Satellite analyst Marco Langbroekit is possible that relatively whole to the reentry of the Earth’s atmosphere, although the reentry trajectory and the seniority of the capsule reduce the possibility that it is intact at the time of the impact With the parachute deployed? The imminent reentry has intensified the follow -up by satellite observers. The amateur astronomer Ralf Vandebergh has achieved telescopic images of the object in which it seems to have a parachute. “There is a compact ball, but several frames show a weak elongated structure on a particular side of the ball,” He said to Space.com. In addition, the object could be tumbos, so it is only visible at times. How to follow the reentry. Kosmos 482 Orbit the Earth every 90 minutes in a inclination of 52 degrees. This means that the reentry can occur anywhere between latitudes 52 ° North and 52 ° South. The space -track estimated reentry window and analysts such as Langbroek focuses on May 10, 2025, with an uncertainty of 2 or 3 days that will be reduced as the moment approaches. The ship will make a series of visible passes from the northern hemisphere at dawn just around the planned reentry dates. Sites like Heavens-Above already include predictions of visible passes for Kosmos 482. When the man walked on the moon. The fall of Kosmos 482 is a tangible reminder of the golden era of space exploration and the intense race towards Venus, which followed the lunar race. This 1972 relic (the last year in which man walked on the moon), will return to a radically different world, increasingly congested by thousands of active satellites and a growing amount of space garbage.

The Canary Islands have seven islands, but only one has escaped from the hordes of tourists. His secret is on earth, literally

by

The Canarian archipelago is officially seven islands: Lanzarote, Fuerteventura, Gran Canaria, Tenerife, La Gomera, La Palma and El Hierro. In addition, we have four islets and a series of Roques (next to a centenary dispute for tiny lands, although that It is another story). The curious thing about the islands is that almost all, to a greater or lesser extent, have ended under the influence of mass tourism. With the exception of one, whose nature gave an “advantage” over the rest: iron. Shine without looking for it. Ironthe smallest, western, less visited and better preserved from all the Canary Islands, has begun to attract the attention of a time to this part, although surely, despite many stores. First was the Netflix series Iron in 2019 the one that put it on the audiovisual map. Later, during the pandemic, he once again occupied headlines in half the world. The reasons: to be one of the first territories of Spain in get out of confinement In June 2020, and for having registered alone A COVID-19 case during the health crisis. Thus came the international recommendations that placed it between the Best destinations in Europe In 2021, but the island continues as is, it has barely changed its leisurely way of life, or its resistance to the transformations that did shape the rest of the archipelago in recent decades. His secret is a paradox: What does not have He does it more strong to the hordes. The island of “No”. The peculiarity of the island resides in what it has decided Do not have: Without chain hotels, without tourist complexes, without elevators or buildings of more than two floors, the island also does not have extensive beaches, although it possesses A network of puddles (natural pools) of an incomparable beauty. Here its geography is key, since reaching it outside the archipelago already implies at least two journeys (by plane, via Tenerife or Gran Canaria, or in Ferry, via Tenerife), since there are no direct international flights or maritime connections from the peninsula or abroad. With just 11,000 inhabitants And a surface that is equivalent to half of Ibiza, the traffic is very small and the sensation remains to be in a territory where modernity has barely touched essential things. And yet, since 2018, iron almost completely self-abused with renewable energies, thanks to its hydro-eolic power plant Gorona del Vientoconsolidating itself as a world reference in sustainability. Indomitable nature. While the major islands of the Canarian archipelago face a growing social resistance to the Mass tourismIron has deliberately adopted a radically different model. Instead of joining the urbanization spiral, direct flights and mass tourism, the island has opted for a strategy of leisurely growthintegral sustainability and an intimate bond with nature. Arising from the ocean 1.2 million years ago For violent underwater eruptions, the island displays an abrupt and wild geography where impressive cliffs, volcanic boilers and dense laurisilva forests coexist with undulating meadows, centenary pine forests and abrupt black rock costs that make it a paradise for hiking, contemplation and, ultimately, an unstable instance. To get an idea, in 2023 Just 20,300 visitors They arrived on the island (in contrast to the more than 6.5 million that Tenerife receivedFor example). Sabinar Tourism to last. There is more, of course. As we said before, since 1997, iron develops an ambitious Sustainable Development Plan which has oriented its tourist model towards a way of traveling with limited impact, focused on the valuation of the natural environment and local culture. They have been created Seven Visitors and Museums CentersInfrastructure has been improved without breaking the landscape balance (the first asphalted road came in 1962 and even today there is only one traffic light), and activities that privilege contact with the environment have been encouraged. In this regard, Davinia Suárez Armas, insular director of Tourism and Transportation, summed up the BBC The spirit of the island: grow without deteriorating the quality of life of residents or compromising their natural resources. In fact, it is possible to travel in less than an hour from the warm coast of the South to the Capital of Valverdecrossing microclimates ranging from arid plains to humid fog forests, where more than a hundred endemic species thrive, including criticism El Hierro giant lizardwhich motivated the entire island to be declared Biosphere Reserve in 2000 and Geoparque in 2014 for Unesco. Resistance symbols. Among closed curves, volcanic landscapes and pastures whipped by the wind, it appears The pasturewhere the most famous trees of the enclave grow: the Sabinares twisted for centuries of Alisios winds, turned into living symbols of the Herreña resistance. In that sense, self -sufficiency has been part of the island DNA since the arrival of The bimbachesBerber people settled around 120. Without rivers or natural lakes, they learned to collect water from the fog, especially from legendary tree Garoéwhose location is traveled today through the Water route. Plus: this 16 -kilometer circular path San Andrés connectsthe tallest town on the island, with deposits, aljibes and remains of primitive hydraulic technologies, all witnesses of a history marked by water scarcity and migratory waves, especially towards Venezuela. The Virgin Downfour -year party dedicated to the Virgen de los Reyes (who, according to tradition, ended the Great drought from 1741), keeps that spiritual legacy that mixes need and faith alive. Self -sufficiency. In 2014, the island opened Gorona del Vientothe pioneer central that combines wind and hydraulic energy thanks to its privileged geography. The system pumps desalted water from a coastal deposit to a volcanic boiler at 700 meters of altitude when there is a surplus of wind, and releases that flow in times without wind to generate electricity with hydraulic turbines. In August 2015, he first managed to supply the entire island for four hours. In 2024, he beat a global record: 24 consecutive days operating exclusively with clean energy, which avoided the emission of 13,708 tons of CO₂ and the consumption of more than 4,500 tons of diesel.

Generating electricity using earth rotation seemed impossible. These physicists have shown that it is not

by

In July 2016, two American physicists, Christopher F. Chyba, from Princeton University, and Kevin P. Hand, from the NASA jet propulsion laboratory, published in Physical Review Apply A very exotic scientific article. In his text they defended the possibility of generating electricity taking advantage of The Earth Rotation Movement. His proposal required to build a device that was able to interact with The magnetic field of our planetbut at that time very few scientists took it seriously. Despite the bad initial reception that his job received, Chyba and Hand have spent the last nine years trying to build his electricity generation machine with the purpose of demonstrating that, indeed, his proposal works. However, during this period they have joined a third physique, Thomas H. Chyba, who investigates in Spectral Sensor Solutions, an Albuquerque company (New Mexico). It is dedicated, among other things, to develop electrooptic sensors to detect chemical, nuclear, biological and radiological threats. Chyba and Hand were right from the beginning On March 19, these three physicists published in Physical Review Research A new scientific article in which they experimentally demonstrate that, as suggested in their 2016 text, it is possible to generate electricity taking advantage of The rotation movement From Earth. To carry out their demonstration they have built the apparatus capable of interacting with The Earth’s magnetic field of which they talked in their 2016 article. Interestingly, this device is very broadly speaking a manganese and zinc ferrite cylinder that behaves like a magnetic shield. The experiment of these three physicists has shown that 18 electricity microvolts were being generated through the cylinder Once they had it ready, they guided him in a north-south direction with an angle of 57 degrees with the purpose of being perpendicular to both to the Earth Rotation Movement as to its magnetic field. And then they placed electrodes at each end of the cylinder to be able to measure the voltage of the electric current that they expected to be generated. And they succeeded. His experiment showed that they were being generated 18 electricity microvolts through the cylinder without any other energy source. According to these physicists, the only plausible possibility is that, as they expected, the land rotation movement is responsible for the generation of this small amount of electricity. When Chyba and Hand proposed their idea in 2016, other scientists criticized it by arguing that any voltage caused by a device similar to that they have finally built would be canceled at the time when electrons were repositioned during the generation of an electric field. But your experiment shows that it is possible to capture that voltage. An 18 microvolt voltage is insignificant in practice. It’s true. However, this is not important; The relevant thing is that, apparently, the proposal of these three physicists works. In fact, your plan goes through climb this technology To generate much more electricity, enough at least to be useful. In any case, there is something important that we should not overlook: its experiment still has to be replicated by other scientists and in other test scenarios to verify that this voltage has not really been generated by any other external source that, perhaps, the protagonists of this article have not taken into account.

Astronauts launched by Boeing are returning to Earth nine months later, in a Spacex ship

by

Butch Wilmore and Suni Williams are returning to Earth after nine months at the International Space Station. It is not an unusually long stay for an astronaut (the Russians They have come to spend three times longer in orbit), but Wilmore and Williams originally rose for a test mission just over a week. What followed was one of the most controversial decisions that NASA has taken in recent years. Express rotation Although How Elon Musk and Donald Trump tell himNASA’s two astronauts have not been really abandoned. The Boeing Starliner ship, with which they went up to the ISS in June, returned empty to Earth for a failure in the propulsion system that caused NASA managers to lose confidence in a safe return for their astronauts. Wilmore and Williams were reassigned, first, to the CREW-8 mission of Spacex. If there had been an emergency in the ISS between August and September, they would have returned in that ship under the seats of the other four crew, without the right suit. In September, the CREW-9 mission reached the ISS with two empty seats and two costumes for both, which regularized its situation. Since then, Wilmore and Williams have had a firm return plan: as soon as the four relay astronauts (the Spacex Crew-10 mission), they would return to Earth together with their two companions of the CREW-9 mission. There were some delays for technical issues (the Crew Dragon ship initially assigned to the CREW-10 mission was not ready and had to be replaced), but political tensions ended up accelerating things. Crew-10 arrived at the ISS during the early hours of Monday. 24 hours later, in the early hours of Tuesday, the CREW-9 mission was decoupling to enter the atmosphere and return to the earth. Normally astronauts spend more time together to catch up on the details of the orbital station, but this time it has been an express rotation. The return flight Dressed in their Spacex costumes, very different from those of the Boeing Starliner ship with those who were thrown into space, Butch Wilmore and Suni Williams said goodbye to their peers and entered the Crew Dragon ship with Nick Hague of NASA and Aleksandr Gorbunov of Roscosmos, the other two crew of the CREW-9 mission. At 5:05 UTC, the Spacex ship decoupled from the ISS autonomously and quickly moved away from the laboratory in orbit using its propellants. The Crew Dragon has been maneuvering to reduce its altitude. It is expected that Amerize near the Coast of Florida at 9:57 p.m. UTC, 17 hours after its departure. The most delicate maneuver will occur 12 minutes before shocking. The ship will detach from its trunk and turn on its engines to exorbitar. Then he will perform his atmospheric reentry, being surrounded by plasma by the speed at which he will cross the gases of the Earth’s atmosphere. When it reaches 5,500 meters of altitude, the two pilot parachutes will open to stop the ship, followed by four main parachutes to 1,950 meters to cushion the shocking. The Dragon ship will play the Atlantic Ocean at a speed of 7.6 meters per second, detaching from its parachutes and bringing back to Butch and Suni after nine months of scientific work and maintenance aboard the ISS. The soap opera will have finished. Images | POT In Xataka | “Stranded” astronauts in space say goodbye to the ISS with a script turn: supporting Elon Musk’s version

Spain has a lot to say in the search for potentially habitable explanets. On this occasion, an international team led by researchers from the Institute of Astrophysics of the Canary Islands (IAC) has discovered a planet in the habitable zone of its star, just 59 light years from Earth. The finding. The newly discovered planet is called GJ 3998 d. It is a superstierra, which means that it is significantly larger than our planet, in this case with a mass six times greater than land. The important thing about GJ 3998 d is that orbits its star Within the “habitable zone”which means that it could have liquid water on its surface, whenever it is a rocky planet like ours. The habitable area. This new exoplanet orbit the GJ 3998which is a red dwarf. This type of star is much smaller and colder than the sun, so the habitable zone is at a lesser distance. GJ 3998 D completes an orbit around its star in approximately 42 days, a sixth part of what lasts a land year. Despite the proximity to the red dwarf, it only receives 20 % more radiation than the earth, which makes it a candidate to house the necessary conditions for life. Neighbors. Another point in favor of this new extrasolar planet is that it is relatively close to us, 59 light years away, which makes it a perfect candidate for more detailed studies in the future. Scientists plan to investigate whether GJ 3998 D has atmosphere and if there are signs of oxygen, which would be a strong indicator of the possible existence of extraterrestrial life. But for this they will have to wait for the future spectrograph Andes of the Extremely large telescope (Elt) of that, who will be able to analyze the composition of his atmosphere. Or to the telescope Exo Life Finder (ELF), currently in development by the Institute of Astrophysics of the Canary Islands. A red dwarf galaxy. Red dwarfs are particularly interesting because they are very common in our galaxy. They constitute almost three quarters of all known stars. In addition, its low mass facilitates the detection of planets that orbit around it. GJ 3998 has three known planets: GJ 3998 B, GJ 3998 Cy the newly discovered GJ 3998 d. This discovery was possible thanks to the Hades project, an international initiative that uses the Nazionale Galileo telescope (TNG) at the Rocque de los Muchachos Observatory, in La Palma, to look for planets around small and near stars.
