The more detailed the process of human exploration of the sun, the better, and it is better to have

I don't know about this. I'll find the information myself.

Why keep learning about the sun? What is the Sun? Only by truly understanding the sun at the core of the solar system can we know what kind of external conditions the earth should have to meet the living conditions of human beingsBecause all the environment formed by the earth is related to the sun, the first to form in the entire solar system is the sun, and then there are eight planets in the solar system.

What year is there a cold winter on the earth right now? In which year there was a warm winter is to study the influence of solar activity, that is to say, the heat emitted by the sun is stronger today, then today may be the heat emitted by the warm winter is less, then today may be the cold winter, this is the most intuitive sharing, and then the sun itself emits a storm of high-energy particles, that is, solar storms, flare sun, these will affect a certain geographical phenomenon on the earth, how does this affect? And if we want to change planets, whether the absence of these phenomena will affect the survival of human beings is something we need to consider.

Because according to the records of the survival and disappearance of many large creatures that human beings have stared at before, we can know that no generation of creatures on the earth can survive forever, especially the higher intelligent creatures, the more intelligent the creatures with the stronger the ability to move, the more they will disappear in the mass extinction of the earth's periodic extinctions. Only about 20% of low-level sapient beings will remain, and we have to prevent itFor the day when the earth suffers an irresistible destruction, what is our way out? <>

If we can study the sun thoroughly and know what kind of conditions the sun has formed a planet similar to the earth, then we can follow the standards of the sun and the earth to find a planet that is as similar as possible to the conditions of the earth, and even a planet that can be immigrated. But we must know that our modern science and technology has only developed for hundreds of years, and in a few hundred years, in a few thousand years, we will not be able to reach it.

The masses love to explore the sun and the solar system. It is for the sake of future generations, if the earth cannot survive or if extreme phenomena occur, is it possible to immigrate. If Yinru has this possibility, Hengyou needs to find another planet.

Because all the hidden or rocky environments formed by the earth are inseparable from the sun, through the exploration of the sun, we can understand the causes of the earth's creatures, from the birth to the extinction of the ancient to the present, and explore the future development direction of mankind.

Because the sun is very important to us, and the sun is also a very mysterious planet, and this is also to promote the development of science and technology, and even to improve the status of the country's sedan chair, so people have to explore the sun all the time.

We can find new substances that can obtain some new information, so that we can get more knowledge, and maybe in the future, we can find a planet suitable for human habitation, which can be completely cracked to relieve the pressure on the earth, and can allow human beings to continue.

Because the sun is very important, the sun is very important to the whole galaxy, so we will explore the sun and guess the situation of the sun, so that we can live a better life.

From the perspective of science, economics and the future of mankind**: Scientifically speaking, the exploration of space can help Kaihu help scientists solve many unsolved problems, such as the exploration of Mars, the weather, radiation, geology, etc., which is very helpful for scientists to further understand the problems of planetary physics and the evolution of the solar system.

There are 8 definite planets (and more if you count dwarf planets like Pluto), we have only one star "the Sun" orbiting us, and within the confines of our system are asteroid belts, rocks of various sizes, tons of solar rays and radiation, and many more. There's so much to explore in our solar system.

Sometimes it is difficult to find because our solar system is about 100 million kilometers long. Even in 2021, we will still find shocking and surprising things related to the solar system. But, of course, the main goal of humanity as a whole is to do what many consider unthinkable.

Beyond our solar system, not only to see it, but to explore it and live on it. To truly be a species that exists between galaxies, rather than just living in a small part of the universe.

The world is so exquisite, like a machine with such a complex structure, that it is impossible to believe that it is a natural object, as if a watchmaker designed and created it all. A closer look at Titan reveals its abundance of geological activity, rivers, deltas, deserts, and the possible presence of liquid methane in rain and snow. Escape from a cold earth.

Jupiter is the largest planet in the solar system, and its structure and composition hide the secrets of the formation of the solar system. The Juno probe, which will arrive at Jupiter in July 2016, will reveal the mysteries of Jupiter's interior and magnetic fields.

Pluto has always been mysterious because it is too far away to discern the structure of the surface even with Hubble. Contrary to previous astronomers' predictions, Pluto has been active in geological activity recently, and what the energy is is still an unsolved mystery. But how much science can Mars really do?

I don't think it's much. A lot of geologists are going to spray me. NASA still loves Mars because the public loves Mars.

It indicates that there will be many Martian missions in the future, including Mars sample return, manned Mars landing, and Martian agriculture. But how much scientific value does Mars have as a planet that has been dead for 4 billion years, is currently a question for scientists to ponder.

Recently, it was discovered that the sun and the solar system were formed in 200,000 years, and now the solar system has been studied and discussed in various aspects, so there are new discoveries in this area.

Research an asteroid that has a lot of minerals on it, and many people are figuring out how to mine it.

The latest research results show that Jupiter may have a primitive form of life, so a gas planet like Jupiter could also have life.

Recent research has shown that the Sun and the Solar System were formed over a period of 200,000 years.

The light emitted by celestial bodies travels through the universe for a certain period of time before reaching the Earth, and we receive this light through our eyes or astronomical telescopes, so we can see celestial bodies. However, we can't directly determine how long they have traveled from the light they receive (also known as the time of the light travel). It is only by measuring the distance of the departing light objects from the Earth and then dividing the distance by the speed of light (the speed of light is constant relative to any frame of reference) that it is possible to determine how long they traveled in the universe to come to Earth.

For most of the celestial bodies in the solar system, their distances can be measured by radar reflectometry. However, in the case of the Sun, radar reflection cannot be used, and other methods can only be used, such as the transit of Venus. Measurements show that the distance between the sun and the earth is about 100 million kilometers, and since the speed of light is about 300,000 kilometers and seconds, the sunlight travels in the universe for minutes before it reaches the earth.

For stars with large extrasolar disparity, usually only a few hundred light-years away, trigonometric disparity can be used for ranging. As the Earth orbits the Sun, the stars that are closer to the Earth move relative to the background sky. By measuring the size of the star's parallax angle over a half-year period, the distance of the star can be calculated using trigonometric functions.

Early astronomers used trigonometric parallax to measure the distance of stars, and the parsec, the most commonly used unit of length in astronomy, came from this. It's just that in popular science, for ease of understanding, light years are now used to convert parsecs. For example, the distance of the Cowherd Star is parsec, and it is light-years after converting to light years, which means that the light emitted by the Cowherd Star traveled years in the universe before coming to Earth.

For more distant stars, the main-sequence star fitting method can be used. The distance of a star is directly related to its actual brightness and the brightness observed on Earth, while the actual brightness of a star in the main sequence phase can be determined from spectral analysis, so that their distance can be calculated.

There are also special stars in the universe, Cepheid variables, whose luminosity changes periodically over time, and which can be calibrated by other methods so that they can be used for ranging. This method can even measure the distance of extragalactic galaxies, which was the first time Hubble established the existence of extragalactic galaxies.

For more distant galaxies, the Type Ia Collision Hood supernova method can be used. Because the generation mechanism of type IA supernovae is the same, they have the same actual brightness, and if their distance and apparent brightness relationship are calibrated, they can be used to measure the distance of distant galaxies. However, type IA supernovae are relatively rare in the universe and are a phenomenon that can be encountered but not sought.

For the farthest galaxies, galaxies that are billions or even tens of billions of light-years away can only be measured by redshifting. The redshift value of the galaxy is determined by spectral analysis, and then the receding velocity is determined by the relationship between the redshift and the velocity, and then the corresponding distance can be calculated by Hubble's law. After knowing the distance of the light travel, you can know the time of the light travel.

For the earth, it can be said that human beings have a very good understanding, according to the current science and technology can explore the places that have been explored, so we will look at the universe, before exploring the universe, we should explore the solar system in an all-round way, this is to pave the way for the future, so with the current scientific progress of human beings, when will the solar system be fully explored? No one can give a definite answer, because science is unknown, and many things can be studied in an instant, but this moment takes a long time to accumulate, at least a few centuries at the current rate.

A few decades ago, the world's connections mainly relied on war, and at that time there were few people who made great voyages, let alone traveled to the world, but in today's trend of internationalization, countries are getting closer and closer to each other, and they have become an indispensable part of each other, which has a lot to do with science, because science we have ships, airplanes and trains to help us transport and disseminate different cultural knowledge, it can be said that every year the world is undergoing earth-shaking changes, and most countries in the world are also exploring the solar system. 50 years ago, a country set foot on the moon, but to this day there is no second planet, so it is unknown if we want to explore the solar system, at least for a few hundred years.

The earth is at least hundreds of millions of kilometers away from the sun, and the farthest distance that human beings can leap so far is only half of it, and the closer to the sun, the higher the temperature, which is not something that ordinary materials can bear, the surface of the sun has thousands of degrees Celsius, you must know that only magma can reach it on the earth, and magma can dissolve almost everything found now, so the future has a long way to go.

Although the future is unknown, the solar system can exist for at least a few billion years, after all, the sun is only in middle age now, and there are at least 5 billion years left, so we have time to explore, as long as humanity has not given up on all this.

At the current rate, it will take 300 years, and now our exploration of outer space is still on the moon, and the moon is still half-understood, let alone more distant planets, and the solar system is a very large galaxy, so according to the current progress, it will be able to get a first glimpse of the door in 300 years.

It will probably take hundreds of years before the solar system is fully explored. Because the current science and technology of mankind can only explore one thousandth of the solar system.

A thousand years. Because the solar system is large and human science and technology needs to be further developed, it will take at least a thousand years to fully explore the solar system.

A This question examines the problem of giving full play to subjective initiative to grasp the law and understand the world, so C and D are not in line with the question. Item B error.

Question 1: A Question 2: C

Question Analysis: Question 1: The period of solar activity is 11 years, and 2011 2012 is the period of strong solar activity, so if you push forward 11 years, the last period of strong activity is about 2000 2001.

Question 2: The flow of charged particles generated by solar activity can cause ionospheric disturbances, which in turn affect radio shortwave communications. Solar activity will affect the earth's magnetic field, magnetic storms, aurora phenomena, when the solar activity is strong, the earth's magnetic needle can not indicate the direction correctly, and solar activity will also cause the earth's climate to be abnormal.

Comments: This question is less difficult, question 1 examines the cycle of solar activity, and question 2 examines the impact of solar activity on the earth, which belongs to the examination of basic knowledge, and also tests the students' ability to use basic knowledge. Effects of solar activity on the Earth:

Effects of solar activity on the Earth:

Effect. Examples.

Defense. Affects the Earth's climate.

The regular sparse changes of tree rings in the subarctic zone correspond to the 11-year activity cycle of sunspots. In peak years of sunspot activity, the probability of climate anomalies increases, and in low peak years of sunspot activity, the climatic conditions are relatively stable.

All countries in the world and China attach great importance to the observation and development of solar activity, and strive to minimize the possible adverse effects of solar activity.

Disrupt the Earth's ionosphere.

The electromagnetic radiation and high-energy charged particle streams emitted when human solar activities are enhanced strongly interfere with the ionosphere in the high altitude of the earth, affect radio short-wave communications, and even cause short-term interruption of various radio communications.

Disturbing the Earth's magnetic field.

When solar activity intensifies, the stream of high-energy charged particles from the sun will interfere with the earth's magnetic field, resulting in a "magnetic storm" phenomenon in which the magnetic needle vibrates violently and cannot correctly indicate the direction.

Produce an aurora. High-energy charged particles rush into the high-altitude atmosphere at high speed in the polar regions and collide with the rarefied atmosphere there to produce pale green, red or pink bands or arcs of light, called auroras.

Natural disaster. The occurrence of many natural disasters on the earth is related to solar activity, such as floods and droughts.
