Mars is “eliminated”, where can humans go when they immigrate to space? Is there really a super Earth?

The earth is the home of human beings. It has given birth to all kinds of life forms since its birth. As intelligent life on the earth, human beings rule the earth. In the process of development, they also have a negative impact on the earth. A lot of damage was done. Nowadays, the earth's resources are becoming increasingly scarce, and the earth's ecological environment has also been greatly damaged. If humans want to develop in the long term, then we must start looking for a "second earth". Judging from the development trend of the earth, , one day the earth will no longer be suitable for human survival. Scientists are also anxious about the development of the earth's environment. As humans continue to develop, the population will become increasingly dense in the future. However, the earth's land area is limited. With the intensification of human expansion, the earth will only become more and more crowded. , so scientists put forward the idea of ??space immigration. American scientists proposed to build a space city. The design is a rotating cylinder with a diameter of 2,800 meters. This space will accommodate 10,000 residents.

Immigrating to outer space is the current main goal of scientists. Hawking once said that humans must immigrate to other planets to escape the fate of destruction, because Hawking believes that the earth is getting hotter and hotter under the influence of global warming. Eventually the earth will become a "fireball", and by 2600 humans will be unable to adapt to the earth's environmental changes and become extinct. Therefore, scientists are currently exploring the possibility of migrating to outer space. NASA Administrator Griffin also said that judging from historical development, it is impossible for species on a single planet to survive permanently. ?We have conclusive evidence that on average every 30 million years, species on Earth will suffer massive destruction; one day we will definitely colonize alien planets, but I don’t know when that day will be?

If humans want to move to outer space, where can we move to? Some scientists once thought that Mars was a good choice, but we all know that Mars is a desert planet with sand dunes and gravels all over the surface, drought and lack of water. How could it be suitable for human survival? As early as September 28, 2015, NASA announced the existence of flowing water on Mars, and in 2018, scientists discovered liquid water on Mars. The following year, the U.S. Curiosity Mars rover also discovered that there were salt lakes on Mars. These Major discoveries have given scientists renewed confidence in colonizing Mars. Elon Musk, CEO of the U.S. Space Exploration Technology Company (SpaceX), has also proposed a Mars immigration plan. Musk has publicly stated that his long-term goal is to migrate humans from the earth to other planets and ensure that the process is safe enough and Low price. But if we want to move to Mars, there is still one problem that needs to be solved? Oxygen. Oxygen is very dependent on humans. Scientist Robert Zuber believes that it will take 1,000 years to create oxygen on Mars.

But it is obvious that humans cannot wait that long. When NASA was studying the planets in the solar system, it also stated that other planets orbiting the sun were not suitable for human survival, so Mars was "eliminated". Dr. Margaret Turnbar, an astronomer at the Carnegie Institution of Washington, summarized the four criteria for a galaxy most suitable for life. The first point is that the planet must have existed for at least 3 billion years, so that the development of the planet can be Stable enough; the second point is that the volume of the central star cannot exceed 1.5 times that of the sun; the third point is that there should be enough iron elements; the last point is that the central star should be in the development stage of being neither a red giant nor a white dwarf, so that the surrounding planets Only complex life forms can survive long enough.

On the basis of these standards, scientists have proposed a "Super Earth", believing that a "Super Earth" can allow human beings to survive. A super Earth is actually a super terrestrial planet. Its plate structure is very similar to that of the earth, and its environment has many similarities with the earth. Only in this way can a super earth be suitable for human survival, making it possible for humans to emigrate into space. Based on these conditions, scientists discovered Beta CVn in Canes, which is 26 light-years away from the earth, HD10307, ??which is 42 light-years away from the earth, HD211415, which contains about half of the metal elements of the sun, Sco18 Scorpio, and 51 Pegasus. These galaxies are considered extremely extreme by scientists. There may be "super-Earth" galaxies.

Scientists have been exploring "super Earths" for many years and finally made a major discovery. In 2017, scientists discovered Gliese 411 and Gliese 411b. Gliese 411b is a hot "super Earth" with a rocky surface. , it is located in the fourth closest star system to the sun and is also the third closest planetary system to the sun. Later, scientists observed an M-type dwarf star named LHS 1140 through the MEarth-South Telescope Array. This star is about 39 light-years away from the sun, has a radius 1.4 times that of the Earth, and a mass that is 6.6 times that of the Earth. In 2019, scientists also discovered a huge super-Earth GJ 699 b 6 light-years away from us. Its temperature is also very similar to Europa.

The exploration of "Super Earths" has not stopped yet. Scientists have been exploring for many years and have discovered many "Super Earths" in space. The discovery of these "Super Earths" will hopefully realize mankind's space immigration plan. I believe In the future, with the rapid development of mankind, we will definitely find the "super Earth" suitable for human survival and realize immigration into space.
