It is a super earth, about 16 light-years away from the earth, and may have adapted to the temperature and atmosphere

With the help of science and technology, when human beings walk out of the earth and see the vast universe, a very important question appears in front of us: is there a life planet like the earth in the universe? Some people may think that although the universe is big, the earth is unique.

But in fact, the vast universe is full of innumerable possibilities, and the impossibilities we think will always become possible in the end. Naturally, the same is true for earth like planets similar to the earth. With the continuous observation and search of astronomical telescopes, many earth like planets similar to the earth have been found. They are less than a few light years away from the earth, and more than a few light years away.

Of course, these earth like planets are found within the scope of human’s existing observation ability, and beyond the observation range, there are countless earth like planets, and it is possible that there may be exactly the same planets as the earth. Earth like planets similar to the earth mean that there may be similar ecosystems, and the possibility of natural life will be very high.

People’s exploration and search for earth like planets mainly rely on optical telescopes, that is, when the planet revolves around the star, there will be some weak light and dark changes when it blocks the sun’s light. If this change is observed by us, we can determine that there are planets near the star. With this method, scientists have discovered at least hundreds of earth like planets in the range of 1000 light-years.

In fact, relying on optical telescopes to find earth like planets, the effect is not high, and the detection range is relatively limited. It is very difficult for such telescopes to find objects in a dark state. If there is no obvious light reflected by stars, we can not find objects at all.

Scientists have long speculated that there may be a ninth planet on the edge of the solar system, but it is too dark there for optical telescopes to observe and find, so it is impossible to really determine the existence of the ninth planet. In addition to optical telescopes, there is another kind of astronomical telescope with more powerful functions and detection range, which is radio telescope.

Different from other star searching telescopes, radio telescopes mainly search for all kinds of radio signals in the universe. Maybe many people think that the probability of sending out strong radio signals in the universe will be alien civilization, but in fact, more than 90% of the cosmic signals are generated by celestial bodies.

It is no secret in the scientific community that celestial bodies can send out their own radio signals. In addition to super dense celestial bodies such as neutron stars and pulsars, many planets can also send out their own unique radio signals.

For example, the earth can send out natural radio signals. Of course, such signals have no obvious regularity, but are more chaotic. The signal generated by celestial bodies is very important for radio telescopes to search for planets. We should know that the propagation speed of electromagnetic signal is the speed of light, and its propagation speed and distance are very fast and far away.

By receiving the signals from celestial bodies in the universe, we can determine the existence of planets in a certain position, and then we can get more information about celestial bodies through optical telescopes for more detailed observation. The radio telescope’s way of searching for stars is a kind of listening mode, just like in the human world, there are very few ears with very strong hearing, which can hear bands that ordinary people can’t hear.

The Chinese sky eye is the most powerful radio telescope in the world at present. Its power is beyond our imagination. It claims to be able to search and receive signals within the current observable range of human beings. Even signals separated by 10 billion light years are likely to be received by the Chinese sky eye.

Since its launch, China’s sky eye has searched for many new pulsars. In addition to searching for pulsars and other objects with very strong signals, China’s sky eye will also search for earth like planets that can emit strong signals. We should know that all planets that can generate strong signals are very likely to be earth like planets that are very similar to the earth.

And China’s heavenly eye has lived up to the expectations of the public. Through its powerful hearing ability, it finally discovered a super earth 16 light years away. According to the preliminary exploration, the super earth is similar to the earth in many aspects, and its surface is covered with a lot of green, which indicates that the planet may have a thick atmosphere and a lot of liquid water on its surface.

From the pictures, we can see that this super earth is also a very beautiful planet, an ecological planet. It is still unknown whether such a planet will have life or not.

Although 16 light years is a tiny distance in front of the vast universe, it is undoubtedly an insurmountable gap for human beings who have not yet been able to walk out of the solar system. If you want to reach a galaxy of 16 light-years, the speed of a spaceship must be at least sub light speed. Even at the speed of light, it takes 16 years to reach the target.

With the current science and technology of human beings, we can only find earth like planets very similar to the earth through astronomical telescopes, and then mark them. Only after the further development of science and technology in the future and the initial interstellar navigation ability, can we send spacecraft to explore.

The future of mankind is bound to be in space, and interstellar colonization will become the mainstream of the future. However, interstellar colonization will not be smooth sailing, but will be full of all kinds of risks and dangers. These potential threats are less from the cosmic environment and more from the unknown alien civilization. We should know that once human beings have the ability of interstellar navigation, contact with alien civilization is an essential event.

Moreover, earth like planets that are very similar to the earth are unlikely to be lifeless, and more likely to have not only life, but also intelligent life. If the birth time is earlier than the earth, then the existence of a civilization stronger than human beings is also a probable event. Therefore, if human beings want to realize the future era of interstellar colonization, they will face greater risks and difficulties.

In fact, it is not necessarily a very lucky thing for human beings to be trapped in the solar system. We will never know what dangers are waiting for us outside the solar system before we walk out of it. Waiting for mankind to become an interstellar civilization, although it will usher in a more brilliant era of interstellar colonization, greater risks of unknown will come at any time, which is not necessarily a good thing for mankind.

However, the pace of science and technology will not stop, and the earth will not allow mankind to survive forever. If we want to get rid of all kinds of constraints, we can only strive to develop science and technology to make ourselves stronger and faster.
