The solar system was born because of the sun, and the sun is a star, its mass reaches 99.86% of the total mass of the solar system, so it has a strong gravity, which can bind all the planets in the solar system, so that they can not leave the sun, only around it.
Like other stars, photons generated by the constant nuclear fusion inside the sun bring huge energy, which propagates outward in the form of thermal radiation. The nearest place can affect the Kuiper belt at the edge of the solar system. Although there are a large number of stars in the universe, many people know that the background temperature of the universe is very low, reaching minus 270 degrees Celsius, which is close to absolute zero.
Maybe many people think that if the temperature of the cosmic background radiation is so low, there will be no place with high temperature in the whole universe. Is this really the case? Many people may have thought so in the past, but after Voyager 2 arrived at the edge of the solar system, a major discovery changed many people’s views. Why?
As we all know, 42 years ago, mankind launched Voyager 1 and Voyager 2, both of which carried the mission of going out of the solar system. Moreover, the two spaceships collected the highest science and technology of mankind at that time. The main mission was to explore extraterrestrial life, followed by some situations on the edge of the solar system.
After 42 years of flight, Voyager 1 is about 21.8 billion kilometers away from the earth and has stepped out of the Kuiper belt into interstellar space. Voyager 2 is about 18 billion kilometers away from the earth and is at the edge of the solar system. The instruments on Voyager 2 are working normally and can send data to the earth normally.
Some time ago, Voyager 2 sent back the latest data to the earth. By analyzing these data, scientists were surprised to find that the temperature at the edge of the solar system is as high as 31000 degrees. What’s the matter? Such a high temperature makes people wonder what happened at the edge of the solar system?
If the temperature near the corona of the solar system reaches tens of thousands of degrees centigrade, it is very normal. As we all know, although the temperature on the surface of the sun is only 6000 degrees centigrade, the temperature of the corona formed by its ejections can reach millions of degrees centigrade. So close to the sun, tens of thousands of temperature is nothing. However, the edge of the solar system is very far away from the sun, and the energy of solar radiation reaching there is very little, so the temperature of the edge of the solar system is very low, and the coldest planet of the solar system is also on the edge.
But now Voyager 2’s data show that the temperature at the edge of the solar system has reached 30000 degrees Celsius, which is really an incredible thing. So how does such a high edge temperature come into being? Later, scientists believed that the high temperature at the edge of the solar system came from the high-speed collision of the solar wind with various radiation from interstellar space and interstellar ions, which produced friction through the collision of materials, generated huge energy, and formed a very high temperature.
In fact, many people can understand this as soon as they think about it. We live on the earth and can see many high-temperature phenomena caused by high-speed friction and collision. It can be seen that in some specific regions of the universe, the places where various interstellar particles rub and collide with each other may be high-temperature regions. Of course, the high-temperature space on the edge of the sun is not as simple as you think. There are many secrets waiting to be solved.
Through the discovery of Voyager 2 in the high temperature space at the edge of the solar system, we once again realized the strength of the solar wind, which brought suitable temperature and light to the earth in the habitable zone, making the earth a hotbed for cultivating life. At the same time, the strong solar wind also forms a high-temperature region at the edge of the solar system, which can effectively ensure that all kinds of lethal radiation in the extrasolar interstellar space endanger life in the solar system.
Many people may also wonder why Voyager 2 is still intact in the edge of the solar system, where the temperature is as high as 30000 degrees Celsius? There may be two reasons for this problem. One reason is that voyager-2’s material itself has very good high temperature resistance. The other reason is that its flying speed is very fast, and high-speed travel can also effectively reduce the damage caused by high temperature.
At the edge of the solar system, there is a high temperature region as high as 30000 degrees centigrade. This discovery not only makes scientists happy, but also has some troubles. We should know that although this high temperature region protects the survival of galaxies in the earth, especially the living environment of life on earth. But it also increases the danger for future human beings to explore and even walk out of the edge of the solar system.
Although the science and technology of mankind is still relatively backward, it is impossible to really explore the edge of the solar system, and it is impossible to go out of the solar system. However, with the rapid development of science and technology, it is inevitable for mankind to go out of the solar system in the future. At that time, whether we go to the edge of the solar system to explore or go out of the solar system, we have to face a high temperature area there, The spacecraft or probe may be seriously damaged.
If the manned spacecraft passes through the high-temperature area, it should be more careful. Therefore, if the future spacecraft wants to go out of the solar system, new high temperature resistant materials must be developed, especially materials that can withstand tens of thousands of degrees. Of course, high temperature is only one of its attributes in the area where the solar wind collides with the particles and matter in the interstellar space on the edge of the solar system. If we can’t fully understand this region, we may be greatly affected in the future plan to go out of the solar system.
Of course, now we have no ability to really understand the situation of the solar system edge, because the speed of the spacecraft is still too slow, it takes a long time to reach the solar system edge. Only when the speed of the ship goes further and it takes only a few days to reach the edge of the solar system, can we fully explore the mystery of the edge of the solar system. At that time, we will find more mysteries of the edge of the solar system, especially the internal mystery of the Kuiper belt, and even the position of the ninth largest planet in the solar system that scientists speculate may also be at the edge of the sun. We are looking forward to that day.
