a primitive galaxy that has stopped spinning much earlier than expected

When we think of a spiral galaxywe normally imagine it in rotating motion. It is logical that we do it. After all, that’s what most people do. Only some may have stopped their spin due to collisions or interactions with other galaxies. It is a process that takes many thousands of years. Therefore, when a team of scientists from the University of California Davis came across a very young galaxy completely still They didn’t believe what they were seeing. “Only” 2,000 million years. The galaxy in question, XMM-VID1-2075, formed 2 billion years ago after the big bang. It is a very primitive galaxy, but the light that reaches us is from a young galaxy, which has not had time to stop its spin as planned. The James Webb Space Telescope has observed her along with two other galaxies with similar characteristics, but those do move. Therefore, this must have something special that intrigues scientists a lot. Different movements. Both this galaxy and the other two had been detected and described for the first time thanks to the WM Keck observatory, located in Hawaii. The James Webb intended to study them in more detail and focus attention on their movement. It has been seen that one of them moves normally and the other in a somewhat disordered way, but both rotate. Only XMM-VID1-2075 has stopped spinning. Yes, it has some very chaotic internal movement, but no circles. Important data. Thanks to these observations it has been seen that this galaxy is very massive, one of the most massive primitive galaxies that have been detected so far. It has also been observed that new stars are no longer forming inside it. All this data leads us to think what could have happened to stop its rotation so soon. An unexpected merger. The authors of this research believe that, instead of many collisions over a long time, this galaxy experienced the early merger of a single galaxy that was spinning in completely the opposite direction. This offset his movement and caused him to stop. It is a hypothesis that is also supported by the fact that there is a large concentration of light on one side of the galaxy. Possibly where the merger occurred. Very few. According to the simulations carried out following this study, there should be very few galaxies like this in the universe. However, it will be interesting to find them, in order to understand what the dawn of the universe was like and the different galactic behaviors that have occurred since then. Sometimes exceptions can help us understand the rule much better.

The US invaded Venezuela with perfidy. A letter suggests that there is something simpler and more primitive with Greenland: vendetta

The greenland crisis has ceased to be a diplomatic scuffle and has become an open pulse between Washington and its allies, and that means an accelerated deterioration of trust within NATO. While Denmark has sent more troops to the islanda letter points to an idea that was not in the pools: that the germ of everything comes from a question of revenge. The Atlantic Rift. The positions at the moment are clear: Trump insists that the United States must “acquire” a strategic island rich in minerals, while Denmark and Greenland repeat that not for sale and they warn of a climate in which the threat of force is no longer taboo. For its part, Europe is beginning to speak not only of political indignation but of economic responses and security, because what seemed like a campaign eccentricity is becoming a structural crisis regarding sovereignty, alliances and credibility. Meanwhile, Russia observe with popcorn and from the sidelines how the Western bloc is fracturing from the inside. From perfidy to vendetta. The most disturbing element is not only the objective, but the real motive that Trump has hinted at: if in other recent scenarios Washington was able to resort to perfidy (the engineering of deception, the calculated movement, the operation that is disguised as something else) here something simpler, cruel and primitive appears, the vendetta. We don’t say it, Trump himself has linked his determination not to have received the Nobel Peace Prize in a letter to the Norwegian minister, as if a symbolic humiliation was enough to break the mental brakes and justify him no longer feeling obliged to “think purely about peace.” That emotional turn turns everything in unpredictable: It would no longer be a cold dispute over the Arctic, but a personal reckoning elevated to doctrine, an explosive mix of wounded narcissism and state power that degrades any rational alibi and leaves its allies without stable ground on which to negotiate. The economic threat and the language of blackmail. The escalation takes shape in a pressure scheme that sounds more like an ultimatum than diplomacy between partners: as we counted yesterdayTrump threatens 10% tariffs on Denmark and several European countries, with the promise to raise them to 25% if there is no agreement. Not only that. In parallel, he reserves the “no comment” when asked about the use of forcea silence that functions as a threat in itself, because it allows each gesture to be interpreted as preparatory. Europe, for its part, is beginning to speak of countermeasures and activate pressure instruments commercial, making it clear that he understands the movement as political extortion. In other words, sovereignty becomes a currency, and the economy becomes the mechanism to bend the will of an ally. Nuuk The gesture that turned everything on. counted the financial times A revealing story this morning. Apparently, the spark that lit everything is almost ridiculous because of the size of figures: the dispatch of a British soldier, two Finns and small Danish, French and German detachments arriving for an exercise conceived as a sign of commitment to Arctic security and solidarity with Copenhagen. The European message intended to be reassuringas if to say that the region is not neglected and that the allies take the northern flank seriously, but Trump interpreted as a challenge responding with commercial retaliationas if this symbolic presence were an anti-American provocation. There appeared a central problem of the crisis: what for some is a defensive gesture, for the White House becomes an affront that would confirm its story that Europe stands up to it. The island is militarized. Faced with this aggressive reading, Denmark has upped the ante on the ground with a more visible and politically charged reinforcement. sending more soldiers of combat and the head of the Army himself to Greenland. They add to the approximately 200 troops already deployed between Nuuk and Kangerlussuaq in the framework by Arctic Endurancewhich is also accelerated and intensified precisely by the Trump’s verbal escalationas if the exercise went from routine to warning. In parallel, the images of soldiers patrolling the center of Nuuk and the presence of a Danish warship patrolling the coast They project the feeling that the island has entered a new phase, where normality is militarized without the need for shots. NORAD moves pieces. The TWZ analysts They also emphasized another movement that occurs at the same time. NORAD advertisement sending troops and aircraft to Greenland to support “long-planned” and “routine” activities, stressing that they are not linked to the current crisis. The timing may be real, but the political effect is inseparable from context: In the midst of escalation, any American movement on the island seems like a message, and any explanation sounds like a textbook formula. The “security argument.” As the weeks passed, in addition, the Trump’s strategic pretext It is beginning to sound increasingly hollow, because Europe is trying to cover the same need (reinforcing the Arctic) and yet American pressure does not relax. In fact, for many observersthe European shipment uncovers the real reason, because if the problem was that Greenland was exposed to Russia or China, then a greater allied presence should be the solution, not the trigger. Chagos as ammunition. The Guardian had a few hours ago another way: Trump has reinforced his vision of the world using the case of the Chagos Islands as a moral example in reverse, calling of “great stupidity” for the United Kingdom to cede sovereignty to Mauritius even if it maintains the island of Diego García leased 99 years for the joint base. In his story, that act shows weaknessand that weakness is what China and Russia “only understand” as opportunity, so Greenland “must” be acquired for national security reasons. The logic is simplistic: neither law nor history rules, but force, and what is given by agreement is interpreted as a kind of shameful concession, even if it is an arrangement to sustain a military installation. Meanwhile, in Greenland. dSince the beginning of the crisis, … Read more
