42 light years from the ground, a super-large "super earth" was discovered, but scientists were worried.

With the rapid development of science and technology, there have been more and more discussions about "space migration" in recent years.

According to astronomers' speculation, there are more than 65438+ billion livable planets in the whole universe, including "super earth".

Astronomers put forward the concept of "terrestrial planet" based on the earth, and listed four conditions that terrestrial planets must meet if they want to have life: organic matter, liquid water, atmosphere and a star that can provide stable energy.

On this basis, if the mass of this kind of terrestrial planet is still very huge, then it is the so-called "super earth". So have we ever found a "super earth"? The answer is yes.

Scientists have discovered an orange-red star whose mass is about 86% of the sun, and a star system has formed around it.

Located in the livable zone of this galaxy is its third planet, numbered HD 69830 d, with a mass of about 17 Earths. After analysis, it is very likely that there is life on this super-large "super earth". And it is only 42 light years away from the earth, and one day, it is possible for humans to reach that planet.

Many scientists were very happy at first when they learned about it, but with the deepening of exploration, they became worried.

The planet HD 69830 d is about 7 billion years old, while the earth is about 4.6 billion years old. In other words, if its evolution process is the same as that of the earth, the technological civilization created on this planet will be 2.4 billion years ahead of us.

To put it bluntly, once advanced civilization appears on HD 69830 d, it will pose a great threat to mankind. But then again, these are just speculations made by scientists based on existing science and technology.

To sum up, the road of human "space migration" still needs to be explored. In order to provide it with more time, what we can do is to protect the ecological environment of the earth. What do you think of this?
