The earth is the home for human survival. Before human beings go out of the earth, we don’t know how big the earth is or what the world outside the earth is like. However, with the advent of the era of human science and technology, we finally have the hope to explore the universe. When we walk out of the earth, we know that the earth is so small and that the vastness of the universe is beyond our imagination.
No one knows how big the vast universe is, but we know that there must be many earth like planets similar to the earth in the vast universe. There is also a great possibility that there will be life planets like the earth and intelligent civilization like human beings. Therefore, after human walking out of the earth, there are two important tasks, one is to find and explore the existence of alien civilization, the other is to find earth like planets similar to the earth.
Another more important reason for scientists to search for earth like planets similar to the earth is to expect to find a second and third home for human beings. We should know that the ecological environment of the earth is constantly being destroyed, and the future Earth may no longer be suitable for human survival. At that time, if human beings want to continue, they can only carry out interstellar migration and go to other new earth to live.
In order to find and explore earth like planets, scientists launched deep space telescopes into space, such as the Hubble telescope. Through the telescope, scientists found hundreds of earth like planets similar to the earth. Unfortunately, these earth like planets are far away from the earth. You know, one of the most important factors that human beings need to consider in the future is distance.
In the vast universe, the distance is measured in light years. If the earth like planet is too far away from the earth, even if it has the same environment as the earth, we can’t reach it. The most promising range for human beings in the future is about 100 light years. So on April 18 last year, scientists launched a new probe, the Tess satellite probe.
Tess satellite probe is the representative work of the latest human science and technology. Its nickname is “planet Hunter”. Its goal is to observe more than 200000 stars in two years, which is a great and arduous task. Tess satellite probe is a short-distance astronomical telescope. Its detection range is about 100 light-years. Only the earth like planets found in this range can be reached in the future.
Soon after the launch of Tess, it brought back good news for mankind. It discovered the first extraterrestrial world. This is a hot Jupiter, about 60 light-years away from the earth. Its extremely bright characteristics attracted the attention of scientists. Such a bright planet shows that it is very close to the main star, illuminated by the star, and there is a lot of evaporation around it.
After discovering this hot Jupiter, it is not difficult to find the main star around it. Through observation and search, scientists found this star. It is a yellow dwarf, just like the sun in the star family, but a small one. Although it is only a yellow dwarf, the mass of the hot Jupiter around it is 10 times that of Jupiter.
In the solar system, the mass of Jupiter is larger than that of the other seven planets, and the mass of this hot Jupiter is 10 times that of Jupiter. Therefore, it must be a giant. Because it is only three astronomical units away from the main star, its surface temperature is very high, and all kinds of materials are constantly evaporating.
So since there are gas giant planets in this stellar system, do there also exist earth like planets? By exploring around the star, scientists have finally found a more strange planet. It is a super earth with a mass of 4.82 times that of the earth, and its volume is also very huge. It can be seen that this stellar system is rich in giant planets, gas planets are much larger than Jupiter, and the earth like planet discovered now is also a super earth.
So does this super earth have a similar living environment? Unfortunately, this will disappoint many friends. Although it is an earth like planet, it is closer to the star, only 0.07 astronomical units, which is 50 times of the orbit of mercury. So close, we can imagine how high the humidity on its surface is.
The ultra-high humidity makes it a real purgatory planet, and it is also in a state of constant evaporation, just like the hotwood star. It may not take many years for its atmosphere to be stripped off, and then other substances will be stripped off, leaving a dense metal core, or even the core will be evaporated.
It is the first time that scientists have found such strange galaxies and planets in a galaxy so close to the earth. At present, scientists have only found a hot Jupiter and a super earth in this galaxy, and maybe there are other planets. We are looking forward to finding earth like planets farther away from the main star in the future. We should know that in the yellow dwarf galaxy, there are galaxies that may give birth to life planets, and there may be earth like planets very similar to the earth in the habitable zone.
However, by observing the evaporation state of the super earth, scientists also think about the future of the earth. It is possible that the earth will face the same fate in billions of years. I believe many friends know that our sun has been burning for 5 billion years, and its life is half done. In a few billion years, with the depletion of hydrogen fuel, the sun began to expand and devour the orbits of mercury and Venus.
At that time, the earth will be very close to the sun’s orbit, no less than that super earth’s distance from the main star. As the earth moves closer to the sun’s orbit, the earth’s humidity will continue to rise, and eventually become a purgatory planet. The atmosphere will continue to be deprived, and the liquid water on the surface will evaporate. Then all kinds of materials on the earth will be continuously evaporated, leaving a dense metal core.
Of course, we don’t need to worry about the fate of human beings. In the billions of years, enough science and technology for human beings developed very strongly. At that time, human beings had already become an interstellar civilization and colonized countless planets. When the earth could not survive, people on the earth could migrate to other colonized planets. If we still want to keep the earth, the parent planet of human beings, we may also transform the earth into a flying wandering planet and let it leave the solar system to settle on other planets.
