150 million kilometers away from the earth, the spacecraft again sent back new photos, showing a strange fireball

There are countless galaxies in the universe, and each galaxy has one or more stars at its center. Our solar system is one of them, and the center is the sun. Eight planets move around the solar system. If you want to know which planet is the most interesting in the solar system, I believe many people will say the sun.

Although it has been more than half a century since mankind stepped out of the earth to explore the universe and launched many detectors, we still know very little about the sun. The light source of the universe comes from stars. Without the light and heat of stars, our universe will be dark without any light. It is with countless stars that the Dark Universe will have a little light.

The solar system is born because of the sun, the birth of earth life, the birth of human beings are inseparable from the sun, without the sun, there will be no earth life and the birth of human beings. The main reason why the sun is difficult to detect is that its temperature is too high. The surface temperature is about 5000 degrees. The more we go in, the higher the temperature is. However, our detector is difficult to get close to the sun and can only observe it from a distance.

Although it is very difficult to detect the sun, scientists have not been trying to understand the sun. Maybe many people think that the sun is a big fireball with nuclear fusion reaction all the time? What’s mysterious and strange about it? In fact, human’s cognition of the sun is still conjectured, such as the nuclear fusion reaction inside the sun, which is also a conjecture of human beings. We don’t know what kind of reaction is inside the sun, and whether it is completely nuclear fusion, because we can’t get close to or even land in the sun. Everything is conjecture.

There are many secrets that the sun has not solved, such as: why is the temperature of the corona far away from the sun’s surface higher than that of the sun’s surface? Why does the solar wind have such a high acceleration? How does the sun eject particles at half the speed of light? These three problems have been perplexing countless scientists. If you want to understand the mysteries of the sun, you have to keep close to it.

We can know more about Mars because the human probe can land on Mars, and we can never know more about it from a distance than from a close view. In order to explore the sun, NASA successfully launched the Parker Solar Probe on August 12, 2018. It will approach the sun with human expectation to solve some mysteries of the sun.

Parker solar detector is a collection of the highest technology of human beings, especially in the aspect of heat insulation. It uses a revolutionary new type of heat insulation plate to protect. Even if the outside temperature reaches 1371 ℃, the maximum temperature of the area covered by the heat insulation plate is only 29 ℃, which is only equivalent to the temperature of the earth in summer. This technology allows the detector to be closer to the sun.

The distance between the sun and the earth is 150 million kilometers, which is a relatively close distance. The Parker Solar Probe soon got close to the position of 2710 kilometers. This distance has far broken the distance between Apollo 2 and the sun in the early days, creating a new record. -When the probe is close to the sun, it also sends back photos to the earth. Recently, Parker solar probe has sent back a group of new photos to the earth.

The sun in the photo excites and shakes scientists. This kind of photo can’t be observed by astronomical telescope at all. It can only be seen by taking a close-up photo of the sun. The bright spot in the picture is mercury. You can also see the phenomenon that only appears on the surface of the star – Corona streamer. This is the solar matter near the sun’s highly active regions, the flickering streaks in the picture.

We feel that the sun is very gentle and calm on the earth, but in fact, the sun is a very hot tempered guy. He often loses his temper. Every time he loses his temper, the sun’s activities will be intensified, and it will do some harm to the earth’s electronic products. It is solar storm. I believe many people have heard of solar storm, and Aurora phenomenon is the manifestation of solar storm Now.

Fortunately, the earth has a strong magnetic field. Generally speaking, these solar storms will not invade into the earth. However, once the solar storm is particularly severe, the earth’s magnetic field will not be able to withstand it, which may bring great harm to the earth. This kind of harm is mainly for electronic products. History has recorded a strong solar storm in the late Ming Dynasty, which lasted for nine days, and the sky turned red.

At that time, people didn’t know that it was a solar storm, and there were no electronic products at that time, so it didn’t cause much harm and loss. If this kind of strong solar storm happened at the end of the Ming Dynasty, human civilization would suffer. Most of the electronic products would be destroyed, and the satellites might also face the risk of total paralysis, resulting in incalculable losses.

Therefore, when scientists study and explore the sun, they are actually preparing for possible risks in the future. When the sun is too active and hot tempered, it will cause solar storms and bring harm to human beings. But if the sun doesn’t lose his temper and wants to be a quiet and good child, then the earth will be in trouble. The decrease of sunspots means that the sun may enter the dormancy period, which brings about the continuous decline of the earth’s temperature, and the earth will usher in the little ice age.

It can be seen that the sun is a very troublesome guy, but the earth and human beings can not leave it. If we want to fully grasp the sun, we must have enough understanding of the sun. Only when we have enough understanding of the sun, we can better make some precautions against the sun. Parker solar probe has only three missions this time. At present, it is about 2700km away from the sun, which is not its limit. In the future, Parker solar probe will continue to circle along Venus, making use of the gravitational catapult of Venus, making it faster and faster, getting closer and closer to our star every time it passes by. Finally, Parker solar probe will reach less than 6 million kilometers away from the surface of the sun Place.

The closer to the sun, the more shocking pictures of the sun can be taken by the Parker detector. I believe that through this mission of the Parker detector, people can have a better understanding of the sun. This is only the first step for human beings to understand the sun. In the future, with the continuous progress of human science and technology, more advanced detectors will be launched to the sun until they reach the surface of the sun.
