NASA became a scientific team looking for aliens, what has been discovered now?

In February 2019, astronomers announced that they had discovered a star system with planets that could support life 39 light-years away. And in the nearby dwarf star "Trappe 1", seven Earth-like planets were discovered, and all of these planets may have water on their surface, which is one of the key components of life, which is also an important location for us to find extraterrestrial life, three of which have such good conditions, scientists say that life may have developed on it, so this may be the first area where extraterrestrial life is discovered, of course, there is water and there is not necessarily life, this still needs to be determined, it can only be said that there is this probability, or exist 39 light-years away.

The first is the discovery of extraterrestrial pulsars, the second is the discovery of fossil Martian microbes, the third is the discovery of a new star in 2015, and the fourth is the discovery of exoplanets that support life.

Today's discovery is that Mars is the most likely to have life, which is called aliens.

In fact, in my heart, I have a lot of fantasies about aliens, so I'm going to talk to you about this question.

1. Aliens.

With the development of the times and the progress of society, we are not limited to the life of the earth, but will move towards the wider universe, where there are countless planets like the earth.

Although there may not be the same environment as the Earth, we cannot rule out the existence of some other creatures, so we will call it aliens. I remember in some ancient times, we always thought that the heavens were round, the earth was square, and that we, the whole human race, were the center of the universe.

2. Fantasy. In fact, I have a very wonderful fantasy about this, what would it be like if those aliens came to our earth one day? They may look very different from us, and the language is very different, but they can communicate with each other using some advanced translation systems, and finally we become friends with her, and they can take humans to their own planet, to experience the customs and travel in space.

When human beings and aliens coexist peacefully, perhaps this universe will be connected, and the entire community of destiny will be completely constructed.

I think aliens are very mysterious, they will have mysterious abilities, they may have superpowers, their appearance is different from that of earthlings, they may look very strange, and their technology is also very super.

For all of us, it's a very mysterious and strange existence, and it may be something that doesn't exist, but I think it's worth exploring.

First, their scientific research is very advanced, secondly, they are very technologically powerful, thirdly, they have powerful spaceships, fourthly, they are immortal, and fifthly, they have a particularly strange appearance.

According to the British newspaper The Telegraph, a NASA plan to send information about Earth to outer space could trigger dangerous consequences, including a potential alien invasion.

According to the report, NASA is moving forward with a new plan to try to send signals to aliens with the help of the FAST radio telescope and the SETI Institute Allen telescope array in Northern California, and invite "aliens" to respond.

NASA calls the program a "galactic lighthouse," and it is reported that the binary code sent to outer space contains important information about our solar system, the Earth's surface and human DNA. In addition, the encoded message concludes with "Earth's receiving address", and NASA says it hopes to receive a response from a distant recipient.

A Ph.D.-led research team at NASA's Jet Propulsion Laboratory in California said that through technology upgrades, binary information can be sent to the center of the Milky Way through the Allen Telescope Array (ATA) at the California Institute for Extraterrestrial Civilization Search and the China Sky Eye 500-meter aperture spherical radio telescope (FAST).

In fact, this is not the first time in human history to send messages to aliens, as early as the 70s of the 20th century, NASA carried out similar activities. At that time, NASA installed metal aluminum plates on the two planetary probes Pioneer 10 and 11, respectively, which were engraved with images of spin transitions within hydrogen atoms and portraits of a man and a woman.

At the time, the news sparked heated discussions from all walks of life, saying that the content was obscure, and even if the aliens received the information, they did not understand the connotation.

Many foreign scientists have expressed concern about this, and most of them have the same concerns as Hawking mentioned ten years ago. He has said that such a move would put human civilization in danger, because the interaction between civilizations at different levels of technological development usually causes danger, and he has also said that such a move could trigger an alien attack on Earth.

Dr. Jim Green, former chief scientist at NASA, believes that life exists beyond Earth and that humanity will make contact with extraterrestrials "in the next few years." He firmly believes that the search for extraterrestrial life can be successful, after all, there are many stars and trillions of planets in the universe, and at least hundreds of millions of these stars and planets should theoretically have all the necessary elements to produce and sustain life.

The former chief scientist of NASA said that humans will come close to aliens in the next few years. Convinced of life beyond Earth, Jim Green said humanity was about to make a "truly amazing discovery."

Dr. Green, who has worked at NASA for 40 years and has an asteroid named after him, told the BBC's Hardtalk that he believes humans will be able to discover extraterrestrial life in his lifetime. "We're making tremendous progress, and now we know that we have more planets than stars in our galaxy," Dr. Green said.

Many of them are located in Earth-like places, where they may have the light that can receive the sun, and they may have water. There may be not only liquid water, but also solid and gaseous water, which we believe are important conditions for the existence of life. We are looking for planets with the conditions that have the potential for life.

NASA's new James Webb Space Telescope will provide images of distant planets that have never been seen before, which will help scientists analyze their atmospheres.

Dr. Green continued, "With our next large telescope, we will begin to tease out what the atmospheres of these planets look like. We will compare the atmospheres of these planets to what we know about them.

Are they more like Venus, more like Mars, or more like Earth? This is a big step forward. I think we're going to see some really shocking discoveries in the next few years.

Experts believe that there is life beyond Earth, and that humans may soon come into close contact with extraterrestrials? Dr. Greene**NASA will be able to find its two mission objectives: "Are we humans alone?"

How did we get here? "What do we do if we do find aliens? Are humans mentally prepared for this?

First of all, NASA scientists who would make such statements are certainly not scientists who study astronomy and extraterrestrial life, and it is impossible for NASA astronomers to say such things. In fact, Colombano is just a computer scientist. To date, there is little evidence to support that aliens have already been on Earth, let alone whether they are carbon-based life.

NASA has also never publicly acknowledged the existence of extraterrestrial activity on Earth.

Since the last century, there have been people who have claimed to have seen alien spaceships on Earth, and even people who have claimed to have had contact with aliens. Sadly, none of the so-called extraterrestrial contact events stand up. The vast majority of these incidents were forgeries and fabrications, while others were simply natural phenomena.

In the vast universe, countless exoplanets will always make people think, will there be life and civilization in those extraterrestrial worlds?

According to the Drake equation, we are unlikely to be alone, and the number of intelligent civilizations in the galaxy is at least one, and at most there may be tens of thousands. It's just that the universe is too big, and it's too difficult for civilizations in different star systems to communicate with each other. Even if radio signals could travel at the speed of light, it would take tens of thousands of years for civilizations on the other side of the galaxy to transmit signals to Earth.

The transmission of signals is already extremely difficult, let alone interstellar travel. According to the theory of relativity, the speed of a spaceship cannot even reach the speed of light. While sub-light motion slows down time and compresses space, it is difficult to get a spaceship to travel at sub-light speeds.

Theoretically, the most efficient known form of interstellar travel is through wormholes. Even if the two planets are tens of thousands of light-years apart, as long as there is a special space-time passage such as a wormhole, the interstellar crossing of tens of thousands of light-years can be completed soon. It's just that opening wormholes requires extremely special negative matter, which humans don't know anything about at the moment.

On the other hand, unlike life on Earth, which is all carbon-based, extraterrestrial life has the potential to depend on other elements, such as silicon. Theoretically, silicon-based life may be more resistant to radiation, making it easier for them to travel to the stars for long periods of time.

NASA astronomer Ellen Stofan believes we have the potential to find extraterrestrial life in the coming decades. However, the place where extraterrestrial life is discovered may not be on exoplanets, but on moons in the solar system, for example, Enceladus.

6. Europa. And this kind of extraterrestrial life is just a simple microorganism, not a sapient creature.

Finally, there is the question of how astronomers would tell the world if they found extraterrestrial life. After all, it was a major discovery that revolutionized the human view of the universe.

Their appearance may be different from that of humans, their height should also be different, and most importantly, their language must be different.

Compared to humans, aliens have ugly appearances, but their brains are more developed than humans, and they are very intelligent creatures.

Their physiology and knowledge reserve are different from those of earthlings. Aliens may have indeed been to Earth, and they may have learned about some of Earth's habits and technological level.
