For five years we have tried to decipher a television signal that came from the sky. The mystery has been resolved

The news for the year in the cosmos has a name and surname: 2024 YR4, that asteroid whose probabilities of impact on Earth do nothing but up. But thousands of kilometers from our planet continue to happen fascinating events. Without going very far, X -ray telescopes have just revealed A superstructure of more than one billion light years. There are more, because for five years astronomers had been looking for a response to a television signal that came from space. The enigma has just been resolved. The mystery of the signals. For five years, astronomers who analyzed the data of the Murchison Widefield Array radio in Western Australia found an unexpected enigma: A television signal from heaven. Since the telescope is located in A radioelectric silence zone Designated to avoid human interference in radioastronomy, the detection of said signal was particularly disconcerting for the community. Even more strange was the fact that the signal It seemed to move through the skywhich led to all kinds of speculation about possible reflections of our own transmissions until, of course, theories about extraterrestrial activity. The answer, as almost always, It was something simpler. The discovery: airplanes. Apparently, the turning point came when Jonathan Poly, physicist at Brown University and leader of the United States research team, He had a revelation: “We said: ‘I bet the signal is being reflected in a plane’”. While this hypothesis had already raised before, no one had confirmed it with certainty. To check it, the equipment used advanced signal processing techniques, as close field corrections and beam formationwith which they managed to better focus close sources of interference. What happened? That the analysis revealed that The reflected signal corresponded to the Channel 7 frequency bandan Australian digital television station. Perhaps more important than that, the calculations on the altitude and speed of the reflective object indicated that It was a plane in full phase of cruiseflying at 11.7 kilometers of altitude at a speed of 792 km/h, data that coincide with the usual characteristics of a commercial flight. A problem for astronomy. As indicated in your recently published studythis type of interference represents a serious problem for astronomers, since Contamin the data and can force the elimination of large amounts of valuable information. According to Jade Chucharmefrom Brown University, “It’s like trying to listen to a friend whispering on the other side of the table while a child screams in your ear.” In this way, every time a television signal is reflected in a plane, It overlaps cosmic waves That astronomers seek to analyze, which can make large sets of observations must be ruled out. Not just that. As they underline, the team’s discovery is key to Develop interference elimination methodswhich will allow filtering these reflexes without losing important astronomical information. However, the problem is not limited to airplanes: satellites in orbit represent an even greater threat. Are we too loud on earth for astronomy? It is the big question that slides from the finding. The number of satellites in orbit It is still increasingwhich aggravates the problem of radio interference. Although scientists are improving data filtering techniques, some begin to question whether planet Earth himself remains adequate place for radioastronomy. According to poor“If we cannot find a silent sky on earth, maybe the earth is no longer the indicated place.” Be that as it may, some astronomers have begun to consider The possibility of moving radioastronomy to spacewith projects that propose the installation of telescopes in the hidden face of the moon, where the terrestrial interference would be minimal. In that sense, the discovery of Poly and his team not only solves a five -year mystery, but also marks a crucial step for the preservation of radioastronomy in an era where electromagnetic pollution is a growing problem. With the advancement of technology, the struggle between the exploration of the cosmos and the signs generated by the human being could define the future of astronomy. Unfortunately for believers, no one was watching TV in space.

The mystery of the best photography made to a UFO is still unresolved. And the United Kingdom Government has the fault

In the set of UVNI eventsacronym for unidentified flying object that over time has been slightly modified to UAP, there are some more relevant than others. Obviously, those who have not been able to answer for lack of information They are the ones who have caught the public’s attention. Without going very far, Incidents revealed by New York Times In 2017 with The pentagon fighters avistando “something”They have turned the world around. And if we stick to a photograph, none like Calvine’s. Encounters in the moors of Scotland. Historius took place One night of August 1990when two hikers who worked as chefs in a nearby hotel claimed to have witnessed an inexplicable event in Calvine’s moors, a remote town in Perth and Kinross, Scotland. While they walked between the fog, They noticed the presence of a huge diamond -shaped object floating in the sky“A stranger” without sound or visible propulsion signs. Its metal structure remained static in the air, challenging common sense itself on the behavior of a conventional aircraft. The astonishment and fear of witnesses increased when A combat plane Harrier appeared on the scenesurrounding the object as if it were in a recognition maneuver. Before the men could process what they saw, the mysterious artifact amounted to high speed and disappeared. One of the witnesses managed to capture several photographs of the moment, images that, years later, would become one of the most enigmatic visual tests in the history of this type of events and considered as Better photography ever made to a UFO. The Ministry of Defense intervenes. Days later, hikers They sent the photos and their testimony to the newspaper Daily Record of Scotland. Andy Allen, image editor of the newspaper, was hit by the clarity of the photographs and decided to send the best to Craig Lindsay, then press officer of the Royal Air Force (RAF) at the base of Pitreavie Castle. Lindsay, surprised by the sharpness and realism of the image, referred it to the United Kingdom Ministry of Defense (MOD), that immediately requested the negatives and other copies. In addition, he instructed Lindsay to contact the witnesses and collect more details. Again and according to the story of one of the hikers, the ship had a metal appearance and levitated without any source of visible propulsion. The conversation with Lindsay was the last time the witnesses gave statements about the event, and His identity was never publicly revealed. Shortly after, the MOD instructed Lindsay to cease any investigation and to leave the case in his hands. One of the two poor quality photocopies of ‘VUFOILS’ (Transparent Plastic Images) made from Calvine UFO photography, published by the National Archives of the United Kingdom in 2009 Photography disappears. That same fall, during a meeting at the MOD offices in London, Lindsay noticed that the best of UFO images had been extended to poster size and hanging on a wall. He was also able to observe the other five photos, in which the Harrier was seen moving around the object while he remained motionless. When consulting with the Ministry analysts, they confirmed that there were no indications of fraud, but that they could not identify the object. Despite the apparent initial interest, Calvine’s case was quickly filed. The Daily Record never published the story, and The photographs disappeared from any public registry For more than 30 years. It is unknown if the newspaper decided not to publish the article on its own initiative or if it received pressures from the British government to hide the incident. Where is the photo? It appears then The figure of the journalist and researcher David Clarkewho was aware of the case in 1996 through the book Open Skies, Closed Mindsby Nick Pope, a former MOD official who worked at the Ministry’s UFO investigation office. Pope described the case as one of the most intriguing in the MOD files and said that the analyzes had determined that the images were genuine, although the object remained without explanation. In 2009, Clarke began to examine declassified documents in the national archives of the United Kingdom and found a memorandum aimed at Ministers of Defense of the time of Margaret Thatcher. In this document, under the title “Defensive Lines to Take”, it was claimed that The mod had not reached definitive conclusions on the objectbut that the plane in the image was undoubtedly a Harrier. In addition, the memorandum indicated that there were no records of unusual activity in the area. Written version of a handwritten summary of Calvine’s sighting in September 1990, published by the United Kingdom National Archives in 2009 The (re) discovery. Over the years, Clarke tried to locate the original image without success, until In 2018 he found the name of a former defense intelligence department in government documents. After locating it on LinkedIn and contacting him, he confirmed that he remembered Calvine’s case and that at the time caused a stir within the ministry. According to his testimony, the most likely explanation was that it was an American experimental aircraft. This revelation led Clarke to Craig Lindsay, who still retained a copy of the photograph inside an old book in his garage. Thus, in 2022, after more than three decades of mystery and After examining with experts if the photograph was realClarke made the image public to the entire world, generating enormous media interest. What the hell happens here? The big question is still unanswered, although obviously there is hypotheses and possible explanations about the nature of the object. The most popular are three. The first is that, yes, That day an extraterrestrial ship was seen. In this regard, some ufologists argue that the object does not resemble any known aircraft, which reinforces the theory that it could be a ship of extraterrestrial origin. The second most commented option speaks of A United States Secret Project. This tip theory to which the object was an American aircraft prototype, possibly from the Aurora program, an alleged hypersonic spy developed … Read more
