A new and “extraordinary” 3I/ATLAS anomaly keeps controversy alive as the comet approaches Earth

Avi Loeb is back at it. While NASA deploys an unprecedented fleet of cameras and telescopes to observe the third interstellar visitor in history, the Harvard physicist points out an orbital coincidence with Jupiter so precise that, in the absence of explanation, it defies chance. A little context. The solar system has a new guest object and, as it happened with its only two known predecessors‘Oumuamua and 2I/Borisov, has not arrived without controversy. The interstellar comet 3I/ATLAS, discovered in July 2025, is on track to make its closest approach to Earth. For NASA, it is a golden opportunity to study the chemistry of another solar system. For the controversial astrophysicist Avi Loeb, director of the Galileo Project, the orbital data has just revealed an “extraordinary anomaly” that, for the umpteenth timehas been associated with a possible artificial origin. A chance of 1 in 26,000. According to the latest trajectory data from NASA’s JPL, 3I/ATLAS will pass the closest point of its trajectory to Jupiter on March 16, 2026. But what’s surprising is not the approach itself, Loeb says, but the exact distance at which it will occur. If a mother ship wanted to “seed devices” on Jupiter or take advantage of its Lagrangian points to park with a minimum expenditure of fuel, it would have to arrive right at the edge of the so-called Hill Radius, which delimits the sphere of gravitational influence of the gas giant. By the date of the encounter, Jupiter’s Hill Radius will be 53.502 million kilometers. The fact that has raised Loeb’s eyebrows? The minimum approach distance of 3I/ATLAS is 53.445 million kilometers. According to the cosmologistthe probability of an interstellar rock randomly passing with this precision by the edge of Jupiter’s Hill Radius is about 1 in 26,000. Engines or degassing? NASA had already ruled out that the “non-gravitational acceleration” observed in 3I/ATLAS came from artificial engines. 3I/ATLAS It is an active comet. As such, as it approaches the Sun, the heat sublimates the ice in its body, creating jets of gas that act as natural propellants, pushing the rock and altering its orbit. However, Loeb argues that this observed acceleration during perihelion (the closest point to the Sun) was of the exact magnitude needed to correct course toward that precise intersection with Jupiter’s Hill sphere. If it were a technological spacecraft, Loeb argues, those observed “jets” might not be ice sublimating, but thrusters performing a gravity-assist maneuver. We will clear up doubts. The outcome of this story will come in the coming months. On December 19 we will have the comet’s closest approach to Earth, an ideal time for detailed spectroscopic observations. A spectroscopic measurement of the speed and composition of the jets will reveal whether they come from the sublimation of ice packs or from technological propellants. If in March 2026, after passing by Jupiter, we detect new objects orbiting the gas giant that we did not send, the history of humanity could change. If not, we will have had the unique opportunity to closely study a fragment of an alien world, which, as NASA tries to argue, is already extraordinary in its own right.

A strangely calm hurricanes season approaches a final uncertain stretch

September 10 is a date marked in the calendars of hurricane -expert meteorologists. It is the date on which the Atlantic hurricanes season usually achieves its peak of activity. But the decreasing trend in the average activity of Atlantic cyclones should not deceive us: there is still a season ahead. We enter the final stretch. According to Experts remember NHC (National Hurricane Center), the American center dedicated to the study of hurricanes, 60% of the activity of hurricanes occurs, generally, after this peak. That is, despite having already gone through the temporary Ecuador of the season (which begins on June 1 and ends on November 30), we could still have more than half of the cyclonic activity ahead. NHC meteorologists also remember that the activity in this part of the season tends to affect the western zone of the North Atlantic, the most vulnerable area to this type of storm because it is in North America and the Caribbean where they usually touch earth. A quiet season. When the Atlantic hurricane season began, there for June, experts predicted a relatively quiet season, but the data show an even greater meekness than expected. When measuring the intensity of a hurricane season, different measures can be used such as the number of storms named, hurricane number, sum of the days with active hurricanes, etc. Another useful measure is that of the index of accumulated cyclonic energy (ACE). According to The data of the Tropical Meteorology Project of the State University of Colorado (CSU), at this point in the hurricane season, the expected Ace based on the Atlantic weather would be 55.8, while the ACE observed is only 39. This implies that the observed data are 30.1% lower compared to those initially expected. Erin, the disruptive force. In addition, there is the circumstance that most of this energy is due to a single hurricane, Erin. Erin’s Ace was 32.2which represents about 82.6% of the total season. What’s happening. That this year’s season was less intense than the previous one was to wait: the temperature in the Atlantic, even though it has not reached the extreme levels seen in recent years and the oscillation of the child has remained in a kind of indecision. A Recent study Led by the meteorologist of the CSU Philip Klotzbach, he highlighted three reasons that could explain to a good extent what we are observing, starting with an “dry and stable” Atlantic. The second of the factors highlighted by the team is a channel pronounced in the high troposphere capable of increasing the vertical wind shear (one of the two determining factors, together with the oceanic temperature, in the formation of hurricanes). The third and last factor would be a descending movement over the African continent, which would be affecting rainfall in West Africa and with it the intensity of waves in the region. What can we expect. Klotzbach’s team coincides with NHC experts to emphasize the possibility that the season resume intensity from this month. “We anticipate that the resume season (intensity), since large -scale conditions seem more tropical and favorable to cyclones later in September,” explain in your text. Therefore they recommend not changing seasonal forecast. The initial estimate of the Tropical Meteorology project of the CSU indicated that the expected oil for the end of the year It is 122.5. On the other hand, if we take the last data (39) and apply the estimate that 60% of the activity occurs in these last months of the season, we would have an expected oil around 100. We will have to wait to see if the trend continues or if on the contrary we see if this season steps on the accelerator in its last months of activity.

More and more countries see how the average age of its population approaches 50 years

Europe ages. That is not No novelty. Not an exclusive phenomenon of the old continent. In other regions of the planet, such as Japan, South Korea or even ChinaThey also suffer more or less clearly The effects of A demography marked by the collapse of birth rate and the increase in life expectancy. With everything and despite the fact that the trend is known, from time to time data arises that help us better understand the scope of change. Eurostat has shared one that shows to what extent the EU begins to become a territory of middle -aged people. The data also reveals another trend: aging is much clearer among the native population, those born within the EU itself, which among immigrants. A figure: 44.7. Recently Eurostat technicians made accounts and calculated that The middle ages From the EU population it is already at 44.7 years. The data is interesting for several reasons. The first, because confirms the gradual aging of Europe. Does A decade That same statistical indicator was 42.5 years ago, two ago it was 39.3 and if we looked back further back, 2001 (the first year documented by Eurostat), it did not reach 38.5. The second reason why the data is interesting is for What reveals us. The median is not the same as the average, but it shows us the value located just in the middle of the statistical series. In this case that means that 50% of the EU population is already above 44.7 years. They are probably even more because the median was calculated based on the statistics of January 2024 and the indicator has not stopped growing over the years. Differences in the EU. 44.7 is the data of the European Union as a whole, which means that there are countries in which the median age is even higher. The clearest cases are Monaco and Italy. In the first, the indicator is already 50.5 years and in the second brand 48.7. In Bulgaria, Portugal and Greece approaches or exceeds 47 and in another half a dozen countries the median overcomes the 45 years. Is The case of Spainwhich started 2024 with half its population above 45.6 years. In 2014, the median was 41.8, two decades ago it marked 38.3 and in 1994 it did not even reach 35 years, which gives an aging. Native Foreign Vs.. Eurostat tables show something else: how immigration is serving to cushion the aging of the EU, just as it has helped some countries (Spain included) To win population despite prick of indigenous birth. According to the data of the EU Statistical Office, on January 1, 2024, the average age of the population born outside the 27 countries of the community club was two years lower than that of the natives. Moreover, Eurostat acknowledges that “compared to the native population, those born abroad are overrepresented between 20 and 54 years” and “underrepresented” in the groups located at the extremes, those of younger and more advanced ages. “59.7% of the population born abroad was between 20 and 54, compared to 42.1% of the native,” They need. A percentage: 6.1%. Eurostat data also reveal that the EU demographic pyramid narrows every time by the base and grows on the cusp, among the older population group. And clearly, in addition. Between 2004 and 2024 the proportion of citizens over 80 years in the EU increased from 3.8 to 6.1%. The statistical office Precise In addition, growth was recorded in all EU countries, with increases especially pronounced in Greece, Latvia and Portugal. The same happened with the group of those over 65: to assume 16.4 went on to represent 21.6%. The other face of the currency. The trend is diametrically opposite among people under 15. At the statistical level, today children and adolescents “weigh” much more in the EU that just two decades ago. If in 2004 they represented 14.6%, now they suppose 16.2%, a setback that has been even more pronounced in countries such as Malta or Cyprus. “During the same period the proportion of young people (children under 19) decreased in all EU countries at the level of the Union, the Fall was 2.4 percentage points, from 22.4% to 20.0%,” Clarifies Eurostat. Why is it important? Because demography is much more than mathematics or simple statistics. The evolution of the middle ages helps to understand where the whole of European society walks and better understand the scope of its aging with All drifts that this implies at a social, economic, welfare or even in defense level. It is not something exclusive to the EU or the West. TO late 2024 South Korea officially became a “overwhelming” society, a label that reveals that about 20% of the population already exceeds the 65 -year barrier. Japan’s example. The clearest case is probably Japan. After decades seeing how its birth rate collapsed, in the country it begins to talk about “Problem 2025”marked by the gradual aging of the millions of citizens who were born during the Baby Boom in the middle of the last century. There the experts already warn of the challenge that this growing imbalance between the population of working age and the elderly will have at a social and economic level.

Goal approaches 100,000 million invested in metoverso, and has no intention of raising the foot of the accelerator

More than ten years have passed since Mark Zuckerberg announced the purchase of Oculus And he began to profile his idea of ​​’Metaverso‘, although the concept did not gain prominence until 2021, When Facebook, Inc. was called Platforms goal, Inc. Reality labs, the division that promotes this initiative, is on the way to burn 100,000 million dollarsand everything indicates that there is still a long way before those promises of incredible virtual worlds, where to work, play and socialize, come true. Virtual and mixed reality glasses, such as Quest Pro goal, Quest 3 goal either Apple Vision Prothey are the entrance door to this type of experience. However, these devices are not yet powerful, light and affordable to gain ground in the general public. A reflection of this reality is Tim Cook’s statements last year, when Apple’s CEO recognized that their glasses are “an early adoption product” intended for “people who want to have tomorrow’s technology.” Goal continues to burn money in metaverso Between 2014 and 2024, Meta has invested more than 80,000 million dollars in its virtual and augmented reality ambitions. The data comes from your financial ones that reflect an expense of 19,875 million dollars and a benefit of 2,146 million dollars to throughout the last year. In other words, the reality Labs division closed 2024 with losses of 17,729 million dollars. Far from lifting the accelerator’s foot, the giant of social networks remains convinced that this is the way, so he anticipates a 2025 with more investment and more losses in reality labs. Few companies in the world can afford with such long term. Meta, of course, is one of them: in 2024 he recorded net profits of 87,109 million dollars in family of apps (FOA), the segment that encompasses products and services such as Facebook, Instagram, Messenger and WhatsApp. Although reality labs is closely linked to metoverso, its reach goes much further. Immediately, this division is the epicenter of commercial products with relative successlike the family of target quest glasses and Ray-Ban Metadeveloped in collaboration with Essiloruxotic. But it is also the laboratory where the future of the company is being built. Last year we first saw Oriona prototype of augmented reality glasses that, According to Zuckerberg himselfit could one day replace the smartphone as we know it. At first glance, Orion glasses are more bulky and robust than the finish lines, probably due to the internal components necessary to project images. And they integrate micro LED projectorscapable of superimposing information in the real world. The idea is to use the physical environment as a canvas for 2D and 3D apps. But there is more. Reality labs is working on the powerful, light and affordable glasses that we mentioned at the beginning. And that, of course, requires a lot of work. At the visualization level, the objective is to achieve a practically indistinguishable experience of reality. But it is not enough with high resolution screens in next -generation glasses, but it is necessary develop technologies that still do not exist to adapt to the complex human visual system. In addition, projects include the exploration of new interfaces, such as electromiography based, which allow controlling devices through neuromuscular signals. As the company itself recognizes, its bet is to develop products that we will not see soon, but will reach its maximum splendor “in the next decade” It will be necessary to see if this goal is still standing with the advance of artificial intelligence (AI), a field in which Meta is investing billions and that, at some point, converges with its vision of metavers.
