2020 is really a magical year. In addition to successive catastrophic events, UFO-related news continues to burst. Originally on March 26, Canadian photographers captured UFOs on the surface of the moon through astronomical telescopes.
March, the so-called UFO on the Moon
Subsequently, the U.S. Pentagon “officially announced” three UFO videos. These videos were originally released without authorization in 2007 and 2017. In the past, the Pentagon has always denied these videos, but until April 2020 On the 27th, they admitted the authenticity of these videos.

On August 19, Russian astronauts broke the news that they accidentally discovered 5 UFOs while shooting the aurora on the space station. These 5 UFOs flew side by side across the sky, and they also released a complete video.

The word UFO may be the most interesting word for people. In the eyes of many people, UFO = alien, But in fact, the full English name of UFO is Unidentified Flying Object, which is actually translated as Refers to UFOs. The concept of UFOs is very broad. Generally, people classify UFOs into four categories: misrecognition of known phenomena, unknown natural phenomena, and unknown Natural creatures, unidentified aircraft.
However, more than 90% of the videos or pictures are fake, and most of the rest belong to the first three, and only a few are real unidentified flying objects.
1. The story of flying sticks
Since the 1940s, UFO has received more and more attention, and people are more and more interested in such unknown events. However, in the first few years, those UFO events that were widely spread Often it was all dictation. Then in the 1950s and 1970s, due to the popularity of cameras, people began to be able to see some photos, but these “UFO” are often a vague picture, which may be the legendary ” A picture of the opening, the content depends on editing.”
In the 1980s and 1990s, cameras began to spread, and at this time there was an unusual “UFO” incident. In the videos taken by many people, we can often find some very vague but long UFOs that do exist. This kind of aircraft is also called “flying sticks” because it is like sticks.

From the late 1990s to the early 2000s, the legend of flying sticks spread rapidly, and more and more flying sticks were discovered. But the strange thing is that in the interviews with many cameramen, they all said in unison that they had never seen such flying sticks on the spot, which really detonated people’s curiosity. Someone sorted out the characteristics of flying sticks: Invisible to the naked eye, it only exists in cameras; it is widely distributed and can be found in videos from all over the world; its tracks are strange, and the flying speed is extremely fast, reaching dozens of kilometers. Hourly; length varies, from more than ten centimeters to tens of meters are found.
The flying sticks vary in size, with the smallest being only a dozen centimeters. Picture/Network

At this time, skeptics appeared one after another. Some people said it was an alien’s spacecraft, some people said it was a life that has not been discovered by us, and all kinds of good people flew based on the blurred image of the video. The stick drew a restoration picture, and even the various body organs of the flying stick were imagined:

However, the fact is that flying sticks are actually flying insects that flew in front of the camera. In 2013, the popular “Approach to Science”, which was popular among the people, had a special program to explain what flying sticks are. If you are interested, you can find this video on CCTV’s official website. In this article, we just give a brief explanation.
This program is a must-see when I was young. Now I can think of its BGM picture/network when I see the picture.
The various videos we see now are actually composed of still pictures frame by frame. As long as the pictures are switched fast enough, we will be able to see a complete and smooth video. This principle and we flip The little book is the same.
So the camera is blunt, it is a camera that takes pictures extremely fast. The pictures taken are rolled in order, so it becomes what we seeVideo.
Our common video now uses a playback speed of 25 or 24 frames per second, which means that we can play 24 to 25 pictures per second. To make this kind of video, we need a camera. Shooting 24~25 pictures per second, that is to say, every 1/24 or 1/25 second, you need to take a picture, and in each shooting, the shutter switch takes half the time, so the calculation is almost every A photo has an exposure time of 1/48 or 1/50 second.
People who have photo experience should know that smearing often occurs when shooting moving objects, so we often take very fuzzy photos. This is the reason for the long exposure time. The same is true for cameras. Flying insects flap their wings extremely fast. Bee wings can vibrate 250 times per second, fly wings vibrate 100 times per second, and dragonfly wings 20 to 40 times per second. These insects are exposed to the camera. In the process, the number of flapping of the wings is greater than the number of exposures, so smears are left in every photo, and these smears are reflected in the video and become flying sticks.
So, you can see that the so-called mysterious flying stick is a device that deceives our eyes. Then, with the help of malicious people, and the love of the people who eat melons, it is abruptly fired. The UFO incident was extremely hot.
II. 2018 UFO sightings in China
On the night of April 27, 2018, there were a large number of North China residents witnessing “UFO” on Weibo, and it was also a hot search. These “UFOs” looked like this:

But in fact, after the rumors of meteorological experts, these seemingly cool “UFOs” are a kind of meteorological phenomenon. This is because when the aircraft flies from high altitude, the exhaust gas emitted by the aircraft contains a large amount of water vapor. The water vapor condenses and turns into ice crystals, thus forming a “trajectory cloud”. We often see fighter jets passing through the sky. , A straight bright line in the sky, this is a trail cloud.

The track clouds that appeared at night this time are due to the high altitude. When the low altitude has entered the night, there is still sunlight in the upper sky. These track clouds are illuminated by the sun, and the ice in the track cloudsJing reflected the sunlight, so in our opinion, this was a UFO incident at night.
Take this event as an example, we can see that when people who have not received professional training are faced with unrecognizable climatic phenomena and astronomical phenomena, they will often recognize these phenomena as UFOs. This is actually The source of most UFO sightings.
Of course, not just the general public, in fact, the military of certain countries also make this kind of mistake:
Three, fake UFO phenomenon
This kind of “eye sightings of UFO” incidents is the most difficult to prevent, especially now that PS technology is developed, Pr software is popular, and CG technology makes it difficult to distinguish between true and false, forged a UFO photo, video, simply Not to mention.
For example, we mentioned at the beginning of the article that Canadian “astronomy enthusiasts” witnessed UFO flying over the lunar surface. This is a completely forged video. Some domestic and foreign netizens have already picked up this video. In the end, the author of the final video had to come out and admit that the video was forged by himself.
It is not difficult to make the moon with Blender, and you can directly make a video with Pr. Picture/youtube
So, do those UFOs that we regard as UFOs and pronounce waixingren exist? do not know. Maybe the UFOs in the videos recognized by the Pentagon are real, and maybe these videos are just smoke bombs used by the US government for some purpose. Without official recognition, we can only keep our eyes open to distinguish those false UFOs, while looking forward to one day in the future that we can really discover the intelligent lives that really exist.
