Here is a compilation of a few “evidence” that is said to strengthen the belief of those who are passionate about the existence of UFOs and aliens: Unexplained stories about UFOs 1. Captain William Schaffner Incident, North Sea On September 9, 1970, Royal Air Force pilot William Schaffner was flying over the North Sea when he spotted a strange object in front of his plane, hovering over the water in the North Sea. He decided to investigate, but a few minutes later radio contact with Captain Schaffner’s plane was lost. Schaffner’s plane was later found on the seabed. However, the dome was closed and there was no trace of the pilot. No one knows what might have happened to the captain. (Photo: Marca) 2. The incident Tehran, Iran On September 19, 1976, Iranian military forces detected an unidentified flying object in the sky over the capital Tehran. When two Iranian air force jets approached the mysterious object, the pilots lost radio contact with the ground. When preparing to fire at the UFO, their weapon system also failed. Only after leaving the vicinity of the strange ship did they resume full control of their aircraft. 3. The Lights of Rendlesham Forest, England The Rendlesham Forest Incident is the name given to a series of scenes that occurred in 1980 following an alleged landing of an unidentified flying object in Rendlesham Forest. The British Ministry of Defense has never considered this event a threat to national security. Therefore, the incident was never formally investigated. 4. US Navy encounters UFOs The encounter occurred during a combat exercise conducted in the Pacific Ocean off the southern coast of California on November 14, 2004. (Photo: History) Pilots of six F/A-18 Super Hornets reported detecting “something” in mid-air, and on radars of US Navy ships and other fighters in the area also appeared. this flying object”. In 2014-2015, fighter pilots of the USS Theodore Roosevelt aircraft carrier strike force also reported recording sensors that detected unidentified aerial objects. Amazing images of UFOs In 2016, the US Intelligence Agency (CIA) released a number of photos of mysterious flying saucers that had appeared in the past that the agency had never made public before. The UFO photo was recorded by Stock in 1952 in New Jersey, USA. At about 4:30 p.m. on July 29, 1952, Mr. Stock was sitting in his yard with a friend when they saw a strange object appear in the sky. He ran into the house to get a camera and took 5 pictures of this UFO. The mysterious object flew at an altitude of about 60m, then accelerated and disappeared. The flying saucer was then described as possibly made of metal, solid and had a transparent dome-shaped upper part. Stock and friends say that the disc is blue or blue, makes no noise and is about 10 meters wide. The image was taken on October 20, 1960 in Minneapolis, Minnesota, USA Another image released by the CIA is a strange, large, glowing disc, believed to have been taken on October 20, 1960 in Minneapolis, Minnesota, USA. This image has never been confirmed to contain any content, but it is believed to be one of the first examples of so-called “stealth UFOs”, the term referring to flying saucers hiding in the clouds to avoid was discovered. Pentagon admits UFOs In May 2019, the Pentagon admitted it was investigating UFOs after naval pilots claimed to have recorded UFOs during training exercises in 2004 and 2015. The program to investigate and study threats from unidentified flying objects (UFOs) took place from 2008 to 2011 and cost up to 22 million USD of the US Department of Defense. This is the first time the Pentagon has acknowledged the existence of this program. (Photo: Defense) In 2020, the Pentagon officially released three short videos showing UFOs, previously released by a private company. The footage, titled “FLIR1”, “GIMBAL” and “GOFAST” was captured by a camera on a US military jet. The videos show what looks like an unidentified flying object moving very fast under the infrared camera. Two of the videos feature officers marveling at the speed of the unidentified flying object. One of them speculated that the object could be a drone. NASA discovers thousands of exoplanets NASA has confirmed the number of extrasolar planets (exoplanets) in the thousands, and we can expect that number to continue to grow as we improve the technology that spaceflight can travel. into other regions of space. (Photo: Insider) This opens up the meaning: There are thousands of known planets that have not been discovered for a long time; and several other planets waiting to be discovered that could be in potentially habitable environments. Existence of the Search Institute for Extraterrestrial Intelligence (SETI) The Search for Extraterrestrial Intelligence (SETI) Institute was founded by Carl Sagan and Jill Tarter, two American astronomers who believe there is more interplanetary life than we thought. (Photo: SETI Institute) SETI’s mission is to “discover, understand and explain the origin and nature of life in the universe, the evolution of intelligence.” The institute’s brilliant minds are working day and night to find ways to trace it. life and aliens in outer space. Another scientific organization searching for intelligent life in the universe actually exists on Earth. It’s proof of how seriously humans care about “aliens”.

The birth of flying saucers It was not until 2015 that this investigation was made public. To date, some of the strangest UFO incidents have been posted online, revealing mysterious objects in the sky that have shocked those who have witnessed it. The most famous case is the “Lubbock Beam” incident that 3 professors in Texas reflected on August 30, 1951. Together, they claim to have seen 20-30 lights in the sky. The objects appear to be about the size of a saucer and have a green fluorescence. “They are smaller than the full moon on the horizon. About 15 such bright streaks, round … We all feel extremely strange “- a professor shared. However, the USAF concluded that the light appeared to be caused by a porcupine (whose breast feathers are white, possibly reflecting light from urban lights below). Of the more than 12,000 UFO cases presented for dissection in the Blue Book Project, the majority concluded “disappointment” as such. The USAF believes that most of the strange objects seen are stars, clouds, civilian aircraft or reconnaissance aircraft. However, 701 of them are still unexplained. New Zealand UFO photo titled “Winter 1951”. Many believe it to be a flying saucer, but the USAF thinks it’s just a lenticular cloud Photo: DAILY MAIL Evaluating the aforementioned massive investigation, Nigel Watson – author of the “UFO investigations Manual” (about UFO investigations from 1892 to the present) – said that in many cases, amateur investigators trying to find an explanation without having time to consider or research. In particular, a particular case that attracted Mr. Watson was the reflection of Kenneth Arnold’s strange object, an incident that can be called the beginning of the extremely popular term “flying saucer” later. Mr. Arnold saw 9 UFOs on Mount Rainier (Washington State) on June 24, 1947. The US government agencies were particularly interested in this report. A similar scene appeared in Tulsa, Oklahoma just a month later, on July 12, 1947. “These objects fly in a diagonal line stretching about 8 km, from the first object to the last object, evaporating,” said Mr. Watson. According to Arnold’s estimation, the above objects were traveling at more than 1,600 km/h from Mount Rainier to Mount Adams. It is “like a saucer if you let it slide across the water”. Soviet secret program Mr. Watson believes that the term flying saucer was born from describing the motion of a flying object rather than its appearance. From secret aircraft to simply birds flying in the sky have been proposed to try to explain the strange phenomena that are reflected, but, in fact, they are still a mystery. In the 1940s and 1950s, the events of encountering flying saucers or even alien abductions in the United States, began to fill the newspapers of this country. However, according to Soviet ufologist and author Paul Stonehill, UFO encounters on the Soviet side at that time were far more direct than those of the US and any object flying over the Soviet Union would have attracted the attention of the military. “The Soviets were shocked that so many UFOs were able to penetrate their borders and unleash themselves without the Kremlin knowing how to control,” Mr. Stonehill revealed on the Daily Star website. During the Cold War and the space race, Soviet forces frequently clashed with UFOs, once they were ordered to shoot down UFOs but failed. Mr. Stonehill – whose research articles on UFOs have been translated into 11 languages ​​- said that when reports of strange phenomena appear in the press, the Kremlin often interprets them as hoaxes. of the Western powers. However, a secret research program called SETKA (Iron Grid) was established in 1977 at the behest of then-President of the Council of Ministers of the USSR Alexei Kosygin, after the famous Petrozavodsk affair, during 48 UFOs appeared in the sky over the city in this Republic of Karelia (then in the Soviet Union). The purpose of SETKA is to identify UFOs as authorities have begun to acknowledge these flying objects may not belong to Earth. According to Mr. Stonehill, most of the files of this sensitive program remain secret. In total, more than 400 unusual mysterious cases, encounters with UFOs or aliens, were studied. The show also changed its name several times to distract the curious. Fierce encounter Through conversations with military intelligence personnel, government officials and Soviet-era scientists, Mr. Stonehill said the most intense encounter between UFOs and Soviet forces occurred in 1953, shortly after leader Joseph Stalin died. A large UFO appeared in the sky over the Taiga region in Siberia. At first, eyewitnesses thought it was a balloon. Soviet military commanders at that time sent a detachment to the scene. However, when trying to attack the foreign object, 3 of the detachment’s planes caught fire. Later, throughout the 1960s, Soviet forces had to comply with a limited order to shoot UFOs because authorities believed that the objects would fight back and destroy any unit that fired. into them. However, in some cases, the UFO side made the move first! In 1990, the legendary Soviet test pilot Marina Popovich held a press conference at the Russian Consulate in San Francisco and published images of what she called an alien plane. The female pilot with the rank of colonel claimed to have seen photos of children of human-alien hybrids. At the same time, Ms. Popovich said that Russian cosmonauts have also encountered UFOs many times.

Misunderstood UFO

In 2012, the Kentucky State Police received a large number of unidentified flying objects (UFO) sighting reports. It was discovered that a shiny mysterious white object appeared in the sky. The local government department could not give an exact explanation, so there were rumors in the local area: “Aliens” had arrived in Kentucky.

Actually, This white mysterious object does not come from a distant planet, but is an ongoing test project of the Internet company Google . They released a number of large balloons in an attempt to build a high-speed wireless internet network in the air and set up an information highway for remote areas to solve the problem of poor mobile phone signal and internet speed.

UFO has always been a topic often mentioned in “unsolved mysteries” book stalls, and occasionally became news in the newspapers. When people find objects in the air that cannot be explained by previous experience, they will be regarded as UFOs, and sometimes they will use their imagination to associate UFOs with possible life outside the earth. however, For most UFO incident reports, what witnesses saw were actually known objects or phenomena It is only due to visual errors, or the phenomenon itself is beyond the scope of the observer’s knowledge, that the UFO’s misjudgment is formed.

In addition to the Google balloon over Kentucky, a wide variety of objects and phenomena have been misjudged as UFOs:

In 1995, over Manchester, England, two Boeing 737 pilots noticed some shiny objects sliding quickly above them. The captain described this object as a fast-flying Christmas tree composed of many shining points. The first officer claimed that it saw a black wedge-shaped object. At that time, the air traffic controller did not find any flying objects within the detection range of the radar, so the incident was classified as a UFO incident. However, by comparing a similar sighting in 1990, analysts believe that what the two pilots observed was actually an obsolete satellite crashing into the earth. The bright light came from the interaction between the satellite and the atmosphere.

Coincidentally, in 1976, two police officers in Devonshire, England, also regarded Venus as a UFO and sounded their siren in an attempt to chase and arrest “aliens.” An American couple also reported that they were being chased by a UFO and claimed to be able to see the window on the UFO with a telescope. However, the UFO position they said was actually the position of Jupiter, and the reason why Jupiter chased them was probably because the visual effect of “the moon walked and I walked” gave them an illusion.

Why are scientists right

Not interested in UFO research?

Whenever a strange sight appears in the sky, the most excited people are probably the scientists. The unknown situation in the sky may be related to the atmosphere, space, astronomy and other disciplines. Whether it is out of curiosity to explore the unknown or the actual need to do research and publish papers, scientists will never let go of any opportunity to discover new things.

However, as early as the 1960s, the scientific community had already formed a consensus- UFO research will not bring scientific breakthroughs .

In the 1950s and 1960s, big news of UFO appeared in the United States every three to five. The U.S. Air Force initiated the Blue Book Project and conducted a systematic study of various UFO reports in an attempt to find possible explanations and reasons. However, due to organizational deviations, this plan has attracted criticism from politicians, journalists, and scholars from all walks of life, who believe that the quality of the research planned to be carried out is low, and there seems to be some acts of covering up information. The thankless U.S. Air Force originally wanted to suspend the plan, but worried that this would lead to more accusations about covering up information, so it decided to delegate the relevant research work to a committee composed of university scholars. After several screenings, Professor Edward Condon of the University of Colorado was finally determined to be the head of the committee, so people are accustomed to calling this committee “the Condon committee.”

Cover of the Condon Report丨wikipedia

After studying a large amount of materials, the committee formed a report with a length of about a thousand pages, entitled “Scientific Research of UFO”, also called “Condon Report. The report analyzed 117 UFO incidents and their causes, and concluded: Further UFO research may not bring scientific progress . However, the “Condon Report” did not completely deny UFO research. It also pointed out that subjects such as atmospheric science and radio propagation may benefit from further exploration of some UFO phenomena.

But this is not to say that aliens have come to the earth and created new phenomena in the atmosphere and radio propagation, but some phenomena that occur in the atmosphere and the ionosphere that affect the propagation of radio waves, which may be mistaken for UFOs. For example, there is a lightning phenomenon called “red elves” in the middle and upper atmosphere. The relatively large-scale “red elves” can extend from 30 kilometers above the ground to 95 kilometers above the ground, and can also be horizontally Extending about 30 kilometers, it looks like a huge “jellyfish” or flying saucer in the sky. This phenomenon, which may be regarded as a UFO, was not recorded for the first time until 1989, and it has become a phenomenon of great interest to scientists. The “Fortune II” satellite developed by my country’s Taiwan region has also carried out observations of this phenomenon from space.

Regarding whether the UFO is an alien spacecraft, the “Condon Report” report argues that ” This is the most unlikely explanation “.

How to find aliens scientifically?

Denying the connection between UFOs and aliens does not mean that scientists are not interested in finding life in the vast sky. Like our country’s radio telescope, FAST, it sets the search for extraterrestrial civilization as one of its scientific goals.

After the use of radio transmission signals, people naturally think that since radio signals can cross the ocean and send information to remote places, it is possible for aliens to use radio signals to spread civilization information to other places in the universe. In 1924, when the distance between Mars and the Earth became relatively close, the United States launched the “National Radio Silence Day” from August 21 to August 23. All radio stations were silent for 5 minutes per hour to listen to the Martians. The signal provides a “quiet” environment. At the same time, the U.S. Naval Observatory used an airship to send a radio antenna to an altitude of about three kilometers, where it conducted signal monitoring.Of course, through detection, we now know The Martians only exist in our imagination, so this much fanfare exploration also ended in nothing. .

When radio astronomy was born at the beginning of the last century, radio astronomers quickly realized that these radio telescopes could not only hear and capture natural signals from astrophysics processes, but also may capture artificial signals emitted by extraterrestrial civilizations.

In 1960, astronomer Drake of Cornell University proposed the concept of a “water hole”. He believes that if other civilizations have the same way of forming life forms as ours, they will naturally have a special liking for “water”. Water is composed of hydrogen and oxygen. Near 1.4GHz, there is an area between the radio spectrum composed of hydrogen and hydrogen and oxygen, which can be used to superimpose artificial signals.

Although Drake himself found nothing in his searches near several stars at that time, the concept of “water hole” profoundly affected the subsequent search of extraterrestrial civilizations. The frequency of water hole is still one of the preferred frequency bands for search.

The FAST telescope plans to take advantage of its high sensitivity to monitor the Andromeda (M31) galaxy near the water hole frequency. If there is a signal from extraterrestrial civilization among the trillion stars in the constellation M31, then FAST must be able to catch it.

If the transmitting device is installed at the back of the radio telescope, the antenna of the radio telescope can also become a signal transmitter with strong gain. Some radio telescopes have both receiving and launching capabilities, and once actively sent signals into the universe in an attempt to get in touch with aliens.

In 1974, the world’s largest radio telescope “Arecibo” sent a signal to the globular cluster M13. The image formed by this bunch of signal codes marked numbers, the elements and basic units that make up DNA, the double helix structure of human DNA, the shape of the human body, the location of planets, and the appearance of a telescope. Since then, there have been dozens of such attempts, and the content of the transmitted signal has also been varied. Among them, there are not only the use of government public funds to develop, but also private sponsorship or private spontaneous fundraising. But so far, people have not received any response from extraterrestrial civilization.

Many people worry that the act of actively transmitting signals will expose the earth to the “dark forest” in the universe. .In order to assess the risk of this behavior, scholars put forward the concept of “San Marino Scale” .

The San Marino scale is calculated as the sum of the signal strength value and the signal characteristic value. Among the signal characteristics, the one with the lowest rating (a rating of 1) is a radar signal without specific information, and the one with the highest rating (a rating of 5) is a purposeful response to them after receiving signals from extraterrestrial civilizations. . Like the special signal sent by the Arecibo telescope to one or more planets, the risk rating is 3.

Although many scientists believe that it may be a dangerous thing to actively contact with extraterrestrial civilizations, there are currently no mandatory rules and regulations that prohibit San Marino’s higher-scale signal transmission behavior, and the scientific search continues…
