Ukraine is seeing objects at 500 km/h. Russia has turned its most lethal weapon into a monster at cruise speed

At this point in the contest it has been clearly clear that, it is not that the war is asymmetric, it is that Russia is attacking Shaheds of thermobárica load and Ukraine with pellets. That reality, in addition, is practically modified every week At a rhythm of updates difficult to continue. The latest: Ukraine radars have begun to see swarins at cruise speed, but they are not missiles. Again the shaheds. Yes, Russia has introduced into its attacks against Ukraine Reaction version of the Kamikaze Shahed drones, model Shahed-238whose benefits (speeds of up to 600 km/haltitudes of almost 10 km and a radar signal similar to that of a cruise missile) make them much more difficult to intercept than the Helix Shahed-136. These drones, with an explosive load of about 50 kg and an estimated range 1,000 to 2,000 km According to the variant, they are practically untouchable for mobile groups with light weapons, cannons or electrical interceptors drones. His deployment in the last mass attack, which left At least 13 dead And more than 130 injured, is a qualitative leap in the Russian capacity to saturate Ukrainian defenses and force the use of expensive Earth-Aire missiles, such as The Nasams either Patriotwhose price can reach Millions of dollars per unit. Tactical impact and adaptation. The introduction of the Shahed-238 seems to be part of A Russian strategy To prove the effectiveness of Ukrainian interceptor drones, developed from high performance FPVs used against recognition aircraft. The Minister of Digital Transformation, Mykhailo Fedorov, recognized that Russia is integrating countermeasures to make fun of these interceptors, which forces Ukraine to adjust tactics daily. Despite the goal of producing A thousand daily interceptorsscalability is limited by Russian attacks on factories, supply problems and the need to constantly relocate production. Ukrainian experts They point That this deployment could seek not so much the direct destruction of strategic objectives such as the wear of the inventory of long -range anti -aircraft missiles, leaving the space open to more destructive weapons. Production limitations. They counted the Twz analysts that, although Russia currently produces some 2,000 Shahed-136 per month And it aspires to reach 5,000, the manufacture of the Shahed-238 is more COmpleja and expensive. Their speeds demand more resistant fuselages, more precise guidance systems and high -cost turbojet engines, which restricts its scalability and diverts resources from the production of simpler models. The dependence of foreign componentsespecially from Chinait could be decisive to sustain or expand production. These limitations suggest that, at least in the short term, Russia will use the Shahed-238 in a combined way with large waves of Shahed-136, creating staggered attacks that saturate defensive systems. Perspectives and threats. The arrival of the Shahed-238 raises a Operational and economic dilemma To Ukraine: neutralize them with Sam missiles long -range is an unsustainable expense, while the most affordable solutions, such as unmanned interceptors, have not yet demonstrated full efficacy against this threat. In the short term, Russia’s most likely tactics aims to combine them with Great Shahed-136 waves To overload the defensive system, forcing to disperse resources and increasing the probability that other more powerful weapons reach their objectives. If Moscow manages to maintain a constant flow, even if it is limited, of these reaction drones, they could become a key element to weaken the Ukrainian defenses and open space to more devastating aerial offensives, thus consolidating a new technological front in the war.

Low intensity magnetars are among the most unique objects of the cosmos. We are now discovering their secrets

The Magenetares They are among the strangest objects in the universe. The key characteristic of these neutron stars is their magnetism, but understanding the origin of this is not so simple. Explaining magnetism. Now a new study He has revealed That the origin of the magnetism of some magnetares, the so-called “low intensity”, is found in a phenomenon we call Tayler-Spruit dynamo. The new job, explain those responsible, resolves a mystery emerged more than a decade ago. Of low intensity. Magnetares are neutron stars, objects of great density that arise after the outbreak of some supernovae that give the death of large mass stars. These objects are characterized by their magnetic fields although, as we have discovered in recent years, these fields are not always comparable. Low intensity magnetares objects have between one and 10 tera-gauss (between 0.1 and 1 giga-tesla), which is one or two orders of magnitude lower than what was used to be considered defining in the “classic” magnetars. Despite this low intensity, this type of magnetar produces x -ray emissions similar to conventional ones. The important difference in the intensity of the magnetic fields of one and the other have led astronomers to press that the magnetism of each other has a different origin. Simulating a star. To understand what was happening in low intensity magnetars to generate their peculaires magnetic fields, the team responsible for the new study He turned to a numerical simulation with which they modeled the magnetic-thermal evolution of these objects. They observed a “dynamo process” (called Tayler-Spruit) that was given in the proto-strolle of neutrons, a process capable of generating low intensity fields from movement such as those observed in this type of stars. Relapse. According to Explain the responsible teamthe key is in the birth of these neutron stars, in the explosions of the supernovas in which they originate. As the model shows, the great of the star expelled in the outbreak ends up falling back to the new neutron star, which makes this faster unleashing this dynamo of Tayler-Spruit The details of the work were published In an article In the magazine Nature Astronomy. Five of 30. Magnetars are objects on which we still have much to learn. To illustrate this a fact can be useful: to date we have only discovered about thirty of these objects in the immensity of the observable universe. Of these only five are what we call low intensity magnetars.

Scientists discovered two objects in our galaxy that they are not able to explain

Japanese astronomers have found two objects in our galaxy that defy all known logic. Although they are the size of typical stars, these bodies are predominantly composed of ice, a feature that does not fit current models of star formation. The discovery has surprised the scientific community, as it raises questions about its origin and if it really They could represent a completely new type of starnever before observed. These objects They have unusual characteristics that make their classification difficult.. Its size is comparable to that of white dwarfs or neutron stars, but its icy composition contradicts any previously documented phenomenon. Some researchers suggest they could have formed in extremely cold regions of spacewhere conditions allowed ice to accumulate on a massive scale. Others consider the possibility that they are remnants of ancient star systems that underwent radical transformations. A new type of star? The discovery of these icy bodies has given rise to an exciting hypothesis: are we facing a new type of star? Conventional stars, whether made of hydrogen, helium or denser compounds, do not have ice as a dominant component. This phenomenon suggests that there must be unknown cosmological processes that allow the formation of these objects. Astronomers still don’t have definitive answers, but They plan to use advanced telescopes to analyze its composition in depth and behavior. Spectroscopy could reveal key information about the presence of other elements and the temperature of these structures. On the other hand, scientists believe that understanding the galactic environment in which these bodies were found could also offer crucial clues. The discovery not only represents a challenge to current theories, but also a opportunity to expand our understanding of the universe. If it is confirmed that these objects are a new type of star, it will be necessary to rethink the foundations of modern astrophysics, opening the door to future research and possibilities in the exploration of the cosmos.
