Astronauts have witnessed UFO explosions in space? How close are alien civilizations to us?

The question of whether there are other intelligent beings outside the Earth may be on the minds of every astronomy enthusiast or whimsical fellow. Are they somewhere in the sky, peering through the thick clouds, every time we search for at them?

And people, of course, have all sorts of amazing ideas about what aliens might look like. There is E.T.'s alien with a big head, a long neck and a small body, ugly and cute, a pair of huge eyes show kindness. There are also the scary monsters of The Opposite Sex who is covered in weapons.

But no matter what the fantasy, humans still think that these extraterrestrials have the same type of head and limbs as humans, and also walk upright, perhaps this is a shared feature of superior intelligence.

Now scientists have confirmed that there are numerous habitable planets like the Earth in the vast universe, among which the possibility of intelligent life or life far beyond the human intelligence on Earth is also quite superior. At least for now, quite a few scientists have a positive attitude towards this question.

Former Soviet cosmonaut Vladimir Kovalyonok, twice a hero of the Soviet Union, believes that extraterrestrial intelligence exists, according to media reports.

The astronaut, who spent 217 days in space, said at a press conference that he had witnessed finger-sized objects orbiting in space while working on Saluting. "It's very difficult to determine the size and speed of objects in the universe," he said. "When we were about to take a picture, the object suddenly exploded into a cloud of smoke and split into two interconnected parts."

Kovalyonok regretted the fact that the phenomenon was not filming at the time. However, on the day of the UFO sighting in Kovalyonok, the ground monitoring center also picked up a large number of electromagnetic waves. It was also witnessed by another astronaut who believed the object was a UFO.

Scientists stress that the search for extraterrestrial life is a shining task for the next generation of telescopes and missions to Mars, and argue that the rocky planets' early formation and evolutionary instability mean most aliens will probably become extinct fossil microbes.

Just as deadly dinosaurs can't walk, talk or breathe, billions of years of fossilized microbes are hard to detect by remote sampling of explanans. Mars, Venus and Earth were very quiet for the first billion years of their history.

Even if life arose on just one of the three planets, it would carry it to other planets in the course of planetary collisions. Nevertheless, over the subsequent 1.5 billion years, Venus began experiencing uncontrolled hot and cold temperatures. So if there was okay on Mars and Venus, it quickly died out.

And Earth gets another planet in the universe that contains the ingredients for life -- liquid water, energy and nutrients. Although the universe is teeming with stars and planets capable of giving birth to life, evidence of alien life suggests that it would be tough for life to persist, even if it were not difficult to create. This may be why i been no extraterrestrials found so far.

Neil DeGrasse Tyson, the national astrophysicist and curator of the Haydn Astrological Museum, explain that life is composed of atoms created by the explosion of a super massive star. This not only prevents us in constant contact with the universe, but also underscores the inevitability of aliens.

"These elements become clouds of gas that condense and collide into the next solar system, a collection of orbiting satellites," he said. The famous Drake equation allows us to calculate how many alien civilizations exist in our galaxy. Based on the basic statistics and the calculations of the equations, the number of potential alien civilizations in the galaxy is up to a million."

Of course, I believe that even if there is further advanced intelligent life or planets with life in this vast universe, it is beyond our current technology to find them.

In other words, we can't initiate a handshake unless they come to us. It be really a good thing for us Earthlings when they do come? When you look down at an ant on the ground, do you have it and give it a ride or do you step on it with your right foot?

Well, this phase of the exploration article is here, like to see this kind of exploration article partner also please give the author a point of concern and praise, I will work harder to write a good article to give you.
