The James Webb captures a lonely object of the size of Jupiter devouring like a miniature sun

by

An international astronomer team has witnessed an extraordinary event: a lonely object, with a mass of just 5 to 10 times that of Jupiter, has entered a violent and prolonged growth burst. Using the combined power of James Webb Space Telescope (JWST) and him Vary Large Telescope (VLT) of the Southern European Observatory, scientists They have observed How this object, known as Cha J11070768-7626326, drastically increases its brightness and its “food” rhythm, behaving like a miniature star. The importance. This discovery represents the first time that a outbreak of accretion of type “exor”, a phenomenon so far associated with young stars, in a body of planetary mass. The finding is not only a milestone in astronomical observation, but also further blur the borders between what we consider a giant planet and a small star. The mystery. CH 1107-7626 is not a planet in the traditional sense that we all have in our mind. Although it has a mass comparable to that of a gaseous giant, I do not orbit any star and is 620 light years from the earth. Is what is known as an “free planetary mass object” or FFPMO (for its acronym in English). The existence of these lonely bodies raises a fundamental question for astronomy: are giant planets that were expelled from their solar systems, or are smaller stars that can exist in isolation? In order to solve this enigma that astronomers have right now on the table, you have to analyze the gas and dust disc that is around, as well as the way of accumulating the material. The fact that Cha 1107-7626 has an album and feeds on it suggests that its origin is more like that of a star. A cosmic feast. Astronomers observed Cha 1107-7626 in a state of calm in April and May 2025. However, for June, something had changed drastically. The object entered a “indulgence.” This means that its rhythm of ‘food’ began to increase, and in this way it reached a mass increase rate of 10-7 masses of Jupiter per year, the highest ever measured in a planetary mass object. As a result of this frenzy, the objective became between 1.5 and 2 brighter magnitudes in visible light and its optical flow increased between 3 and 6 times. This outbreak remained active for at least two months, since it was still on the end of the observation campaign in August 2026. But the most interesting thing is the speed it has. According to the observations made with the Vray Lark Telescope of the European Observatory, the growth rate is really aggressive, with a record rate of devouring 6,600 million tons per second of dust and gas. Great footprints. Beyond the increase in brightness, the telescopes captured detailed physical changes that reveal the nature of the event. A hydrogen emission line, known as Hα, developed a “double peak” profile with a red displaced absorption. According to the authors, this profile is a “distinctive brand” of the accretion channeled through magnetic fields, a process called “magnetospherical accretion” observed in young stars. But the most surprising finding was the change in the chemistry of the disc. At first, changes in the emission lines of the hydrocarbons molecules that came from the disc during the outbreak were seen. But water vapor also began to appear with a characteristic emission around 6.6 µm. This appeared during the outbreak where there was nothing before and is relevant because it is the first time that chemical changes of this type are observed caused by an increase in accretion. Relevance. This event classifies Cha 1107-7626 as the first “exor” of known planetary mass. Exor outbursts are significant accretion events that are considered key episodes in the early evolution of the stars. They can deeply affect the physical structure and chemical composition of the protoplanetary disk, potentially influencing the early stages of planet formation. Observing this process in such a small object demonstrates that the violent and fundamental mechanisms that the stars build also work at planetary scales. The study of Cha 1107-7626 offers an unprecedented vision of the accretion in the lower mass objects of the universe, providing a new window to understand how both smaller stars and the largest planets are formed.

In 2015, the US revealed the meeting of two fighters with an “unknown object”. China has just presented it to the world

by

At the end of 2017 the New York Times launched One of that news that is remembered for what it could mean. A secret program of the Pentagon was revealed that was dedicated to investigating the threats raised by possible UFOs. And among all the information, the star news: the encounter of an unidentified object with two combat fighters (with video included). The origin of those strangers in the sky has never been confirmed. Until China has announced something. The echo of the “gimbal”. As we said, that object video called as “gimbal”, captured by A F/A-18 From the US Navy, he unleashed a global debate on inexplicable aerial phenomena and technologies beyond known military capacities. Today, almost a decade later, China, through the Zhengzhou University of Aeronautics, has presented A tracing of what we saw in those images, an experimental take -off and vertical landing drone (Vtol) whose design, surprisingly, reminds that of that mysterious artifact: a fuselage With elliptical wing in closed ring -shaped, reinforced by vertical stabilizers and four rotors located at the binding points. One of the Chinese Experimental Drones in Test Flight in Zhengzhou, Henan Province The Chinese revolution in Vtol. At first glance it seems A flying spindle more than a conventional aircraft or quadcopter. However, in that unorthodox form an engineering is hidden that combines the best of multi -reliable and fixed -wing systems: maneuvering capacity and vertical support to operate from ships, irregular land or even aquatic surfaces, and at the same time aerodynamic efficiency in horizontal flight, thanks to a wing whose slope of support curve overcomes In more than 100% to that of a straight wing. Radical aerodynamics. Beijing researchers have that the annular wing channels high pressure flows and delays the loss, which allows stable to fly At low speeds or high attack angles, key conditions for military recognition missions in complex environments. The horizontal stabilizer mounted at the ends avoids internal turbulence and improves control. Plus: Tunnel tests and test flights confirmed that the device maintains the adhered flow even in extreme conditionsvalidating computational models that predicted a leap in benefits. A close look at DRON VTOL Chino Purposes. Its robust modular structure allows, on paper, integrate Optical sensors, thermal cameras, rescue equipment or supply capsules, which makes it a multipurpose platform for both military missions (battlefield supervision, maritime surveillance) and For civil applications (Environmental analysis, rescue in difficult access areas, light emergency transport). Limitations and margin of improvement. The great challenge is still The aerodynamic draginherent to the geometry of the closed wing. In that sense, researchers They have underlined that work to refine the profile to reduce pressure resistance and optimize the support/resistance ratio. Plus: They seek to perfect control algorithms to minimize unnecessary corrections that generate induced drag, and also study “more stylized variants designed to operate from war ships”, which would multiply its strategic value in naval operations. Of speculation to the battlefield. Thus, what for much of the world was A ufological unknowns A decade ago, China has now translated it into a tangible system, the result of the convergence of academic research and, of course, military pressure to reach the next generation of drones. If in the cold war the boldest experiments were on paper, today engineering (and China goes in the top positions) manages to validate designs that were just a few years ago as pure fantasy. The similarity with the “gimbal” is casual or intentional, but the truth is that the drone opens a different aerodynamic languageone in which the borders between science fiction and military development are blurred.

The most unexpected object has become the last battlefield of Catalan independence for a detail: the letter e

by

A letter. The E. thus, in capital letters. And a fine. Capital for some if we consider that it is about paying 200 euros for covering a letter. Because that is the sanction that those who cover in Catalonia are receiving the letter E of the registration of their cars. The same that identifies the plaque with Spain. A lyric. And what lyric is it? The E. of “Spain”, “State” and “confrontation”, to give only some examples. At least for those who consider that this letter in their enrollment is an act of submission to the Spanish State and, therefore, is a cause for political confrontation. That letter that some Catalan independence disappears from their tuition to replace it with the CAT letters, next to a SENYERAas a political claim or small subversive act before what they consider the submission of Spain in the region. It is not new. The confidential collects the return of this way of acting by some Catalan independence. But this act of protest is not much less new. At the end of 2024a Catalan was fined for this reason, when considering the Mossos d’Esquadra that had manipulated the registration, which is considered a serious infraction that entails a sanction of 200 euros. But these attempts to replace the license plates either since then. Already in the last decade You can find some publications that point out this way of acting by some drivers. In some yes the European Union flag was maintained. However, it has been in the last two and three years in which the most noise has been generated. The Galician case. But it has been in the last three years when the phenomenon has taken special relevance. In 2024 a driver complained in social networks of having received the aforementioned fine. In the answers there were those who assured that carrying the CAT on the registration was not illegal. The origin must be found in Galicia. There, Bieito Lobeira, Secretary of Organization of the Galician Independence Party BNG, was fined for covering the E of Spain by a GZ in reference to “Galiza”. After various resources, Lobeira won the procedure because it was pointed out that the small modification did not prevent the correct reading of the registration. To this are grabbed those who act in this way, such as David Miñana (ANC leader) either Jordi Cabré (writer). The matter is slippery because in article 49.4 of the General Vehicle Regulations the following is specified: “It is prohibited that the registration plates be placed, registered or painted ornaments, signs or other characters other than those indicated in Annex XVIII, including advertising inside them (…) It is prohibited that in the anterior and posterior parts of the vehicles they will be placed unauthorized complementary plates or fix or paint marks or distinctive marks or distinctive Difficult readability or may induce confusion with the regulatory characters of the registration plates “ However, in the Traffic Law, where the serious sanctions (200 euros) are reflected, it is specified that the following compliance is sanctioned: “Failure to comply with the obligation of any driver to verify that vehicle registration plates do not present obstacles that prevent or hinder their reading and identification” Lobeira won when the judge understood that he took part in his appeal that the GZ letters did not prevent or hindered the reading and identification of the registration. 25 years. In the newspaper AraThey point out that this fight for the letters of the registration has been living for a quarter of a century. In 2000, the Spanish registration plates changed. They adapted to the obligation to carry the letter E and the flag of the European Union for the identification of a vehicle outside the country of origin. However, the government of José María Aznar also eliminated the references that existed to the regions. Before the year 2000, Spanish registrations were made up of one or two letters that referred to the province, four numbers and two additional letters. Already then The nationalist parties and the United Left complained about the absence of the autonomic badges. Already at that time some media and independence groups they encouraged this little protest actiondistributing stickers to incorporate into registrations. And in Europe? The truth is that in Europe there is a good handful of countries that have maintained regional badges despite having to change the registration plates to adapt to European regulations. In France, in Germany or in Italy Shields, letters or any other badge that specifies the region of origin of a vehicle are maintained.

robots capable of intercepting any close object

by

Short. During a public talk at the University of Nankín, a researcher at the Chinese Academy of Sciences (CAS) He explained that they are designing A “fast response system” for the Tiangong Space Station. The active defense system, which has no precedents in the context of a space station, would deploy small propelled robots capable of grabbing and pushing any artifact that invades the station exclusion zone. How it works. The objective declared by the National Space Science Center is not to destroy, but to take away the intruder to protect the crew and its own infrastructure. Each tugboat would carry an autonomous propulsion system and an arm or fastening ring. Before launching a robot, the system would consider less aggressive options, such as an evasive maneuver or an altitude adjustment of the station. Only if the risk persisted, the device would be sent. After evaluating the path of the unauthorized visitor, a tugboat robot would anchor him and displace him a few kilometers outside the tiangong orbit. This does not go from space war. On July 1 and October 21, 2021, China had to perform emergency maneuvers to prevent the Tiangong Space Station collide with two satellites of the Starlink constellationwhich descended from an orbit of 550 km to 400 km, the usual altitude of Tiangong. Although SpaceX states that their satellites have automatic evasion protocols, China explained to the UN that the proliferation of large constellations “reduces the operational security margin” and makes real -time coordination difficult to protect its astronauts. Or yes? A Reuters analysis He described the Chinese initiative as a “first step towards possible orbital battles”, although he acknowledges that, if the non -lethal nature of the robots is confirmed, it would be physical deterrence rather than a weapon in its classic sense. Other countries already develop similar coupling and trailer systems to withdraw Large pieces of space garbagesuch as dead satellites, old rocket stages or damaged ships. The difference would lie in when and against whom these systems are used, taking into account The military escalation of space and The proliferation of spy ship. Does not violate space law. Although mass details, fuel or number of robots are confidential (such as the date of planned deployment), the outdoor space treaty only prohibits to place weapons of mass destruction in orbit: it does not veto conventional kinetic devices, or towing systems. If the robots limit themselves to pushing without damaging, they would fit into the principle of use for peaceful purposes. However, the potential to force the trajectory of the ship of another state can raise disputes on “harmful interference”, a concept collected in the same treaty. For now, we can leave it that China is preparing an active “orbital escort” system. Image | CSA In Xataka | Two years ago, the China Space Station did not exist.

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

The US has detected an object in space with strange behavior. The source that released it has also located: Russia

by

Last year there was a fact that formalized the rhetoric of the “spatial war” It was a fact. It was known, in some cases it was intuited, that the United States, Russia and China had transferred their confrontations hundreds of kilometers from the earth through their satellites. However, in December any glimpse of doubt was cleared: United States He designed the bases of a war attack in space. Now they have detected something unusual, and their source comes from Moscow. First was surveillance. In March, The CNN counted that the Pentagon had intensified the surveillance of the spatial activities of Russia and China in the face of growing evidence that both powers are testing New capabilities Offensive in orbit. As American defense officials then said, Russia had carried out coordinated satellite exercises that simulate attack and defense tactics, including maneuvers in which several satellites surround and isolate another, demonstrating a possible scenario of neutralization of enemy ships. China, meanwhile, had executed similar maneuversincluding the closed formation of satellites and offensive approach practices, actions that reinforce suspicions about the growing militarization of outer space. Three satellites and a stranger. Thus we arrive at the news of these days. Russia has launched space three highly secret satellites (Kosmos 2581, 2582 and 2583) that have revived concerns about a possible preparation for space war. On February 2, the satellites were sent to orbit aboard a Soyuz rocket, without Moscow revealing details about their purpose. Not just that. To the unusual maneuvers they have performed since their deployment, the recent appearance of A mysterious objectpossibly released by the Kosmos 2583 satellite on March 18, whose strange draw Observe with concern. The United States’s space force has already cataloged the new object, while some speculation suggests that these satellites could be practicing “attack and defense” tactics orbital, designed to isolate or neutralize enemy satellites in case of a future conflict. Trajectory of the object detected Theories Although astrophysicist Jonathan McDowell, from Harvard-Smithsonian Center, nuanced interpretations Alarmists when considering that the observed maneuvers can simply be due to similar orbits, recent history also reinforces skepticism. In 2022, Russia had already launched the Kosmos 2558 in the same orbital trajectory as an American military satellite, which was interpreted as an act of spatial espionage. The geopolitical context and the background of the Kremlin in the matter of covert technologies They raise suspicions that this new satellite trio may be carrying out surveillance missions, interception or testing tests Antisatellite technologiesalthough for now there are no conclusive evidence of hostile actions. The “conquest” of space. We said it at the beginning. The maneuvers attributed to satellites Kosmos 2581-2583 They are framed in a broader scenario in which both Russia and China would be exploring New combat capabilities orbital. The Recent CNN reports They quote officials of the United States Department of Defense, who say that both countries are carrying out military training in low orbits, a key zone for their proximity to land and its frequent use for communication, recognition and intelligence satellites. This trend reinforces the fear that space will be consolidated as a new confrontation field Strategic, one where powers develop technologies to deactivate, interfere or even destroy enemy space assets. Uncertainty and surveillance. So far we write, the nature or function of the object released in March has not been determined with certainty, which increases the tension around this satellite trio. McDowell explained That between February 25 and March 14, proximity operations were registered between the satellites, and that two of them passed near Kosmos 2583 on March 7, although it could not be confirmed if there was an attempt at offensive coordination. Even so, the US spatial force maintains close surveillance on the orbital movements and patterns of these artifacts, given the possibility that it is covert tests of new military capacities in space, a dimension that is no longer purely scientific or commercial, but also tactic. The challenge of “interpreting.” In the background, a problem that until now had not taken place in space, that of the opacity of the nations with respect to the missions of their satellites and the repeated use of covert technologies in their space operations that make it difficult to obtain certainty. In an environment where the simple fact of sharing orbits or making approaches between satellites can have both harmless and aggressive aims, analysts, in this case of the United States, must move between caution and prevention. As We already explainedwhile the calls multiply to establish clear international standards on behavior in space, Washington and its allies already consider spatial domain as a Active strategic theaterand each new mysterious object, such as the newly released by Kosmos 2583, adds one more tension layer to technological and military rivalry in orbit.
