What is it like to see the sun from space, and how spectacular is it?

All the planets in the solar system revolve around the sun, which is for the eight planets.

How other planets rotate, we humans are still further a**, and we can't draw an accurate conclusion to generalize the planets of the entire solar system. So about the fact that we can now have the technology to go to space, what is the scene of the sun in our space? How spectacular is it?

The sight is very beautiful and the shock is unprecedented. The main reasons are as follows. <>

1. If we stand in the universe, we will not be affected by the earth's atmosphere.

a visual obstacle. First of all, the first point is if we are standing in the whole of outer space.

With our sun, we will not be obstructed by an atmosphere inside our planet, which is one of these clouds, obstructing our human vision. Therefore, a true face of the sun will exist in our eyes, ** the sun can bring us a very shocking experience, we will find that the sun its color is very red, and the light emitted, we human beings with the naked eye**, will cause a very serious damage to our naked eye, but this is for the problem caused by a long time**. <>

Second, we can see the sun as it really is. In addition, we can see the true face of the sun, which is very huge, a hundred times larger than the earth we live on, and its mass is nearly 50 times larger than our earth. So the sun that we see is a great planet, and such a planet fills our entire interior with all kinds of energy.

3. In short, these are the stars in the galaxy in which we currently live. Finally, this is the only star in the galaxy we humans live in, and it brings an unprecedented experience, and it is the big brother of the eight planets that rule the earth.

There is no atmosphere in space, and you can clearly see the face of the sun. However, because the UV rays are too strong, you need to wear special equipment, otherwise the eyes will be burned by the UV rays.

If you look at the sun from space, it will feel like a huge fireball, and the temperature is very high. It looks spectacular.

Marveling at the vastness of the universe, the sun in our eyes is like a fireball.

What can be seen in space can be described in space, or you can describe the scene on Earth in space.

1. The Himalayas.

The world's tallest mountain can also be seen from space. The highest mountain range separates the Indian subcontinent from the Tibetan Plateau, where Mount Everest, the highest mountain in the world. The Himalayas include hundreds of mountains that rise above 7,200 meters above sea level.

Many areas of this mountain range are also sacred in Hinduism and Buddhism.

2. Amazon River.

The 4,000-mile-long Amazon River and its tributaries can also be seen from space. This photo** was taken by an ISS crew member in 2006. In this case, it forms a long network, like a line that can be seen from space.

In space images of the Amazon River, the color of the water appears to be very dark due to the soil of the lowland forest.

3. Ganges Delta.

The Ganges Servic Delta is the largest delta-forming area in the world and can be found in the Bay of Bengal, parts of Bangladesh, and the Bay of West Bengal in India. It covers an area of 220 miles, and this amazing geographical feature can also be seen from the Earth's orbit. When the river is empty, it is possible to see a large amount of sediment in this area.

Human beings have been born for about 5 million years, from the beginning of the last century, finally got rid of the shackles of the earth and flew into space, in 1969, American astronauts landed on the moon for the first time, opened a precedent for exploring the moon, to this day, a total of 12 astronauts have landed on the moon, astronauts have left the earth that has raised human beings for millions of years, they will always reluctantly look back, when they see this magical blue planet in space, what will they feel in their hearts?

So far, there are only 12 human beings who have successfully reached the moon and observed the earth from the moon, and they are the astronauts of the Apollo moon landing program in the United States, which everyone is very familiar with. When they talked about what it was like to look at the Earth from space, they all expressed a deep sense of loneliness and helplessness.

Astronauts are one of the special talents selected in ten thousand, after special training, they have a high IQ and high psychological quality, so what is the reason that can make astronauts with excellent psychological quality feel afraid? One of the reasons is that after they leave the earth, they have infinite concerns in their hearts, and they will have an unrealistic feeling when they look at the earth from space, because as human beings living on the earth, in their hearts, the earth is their own, it is great and sacred, and it is eternal, but after they go to space, they find that the earth hangs alone in the dark space, and in the face of the stars in the sky, the earth seems small and insignificant, and this psychological contrast is difficult to adapt.

Earthlings' measure of the universe is the common sense of life on the earth, 24 hours a day, there are morning, noon and night, the earth has wind, rain, thunder and lightning, early morning rain and dew, colorful, but in fact, when they leave the earth, all common sense will be broken, Mercury can experience several sunrises a day, Venus is longer than a year, astronauts look at the earth on the moon 380,000 kilometers away, they will find that the earth seems to be standing still, on the moon, The time from dawn to noon is about 168 hours, and the same time from noon to sunset is 168 hours, followed by a long night of 14 Earth days, which is a long day on the moon for earthlings.

It must be very shocking, in the boundless space, the huge blue planet is particularly eye-catching, and it looks very spectacular.

When human beings look at the earth from space, they will feel a great fear that their position is far away from human civilization, and they will be very afraid when they look at the place where they live.

It's like looking at ants, because it's so far away that you can't see anything clearly.

Through the astronomical telescope, people can see that the surface of the sun is a vast and terrifying scene: some places are like shady green forests on the earth, some places are like the prairie on the earth, and some are like wheat fields blown by the breeze on the earth. The Sun, with a radius of 700,000 kilometers (about 100 times the radius of the Earth), is filled with hydrogen, where the density of hydrogen is 1,1000 times that of water on Earth.

The "microfibers" that "stick" to the surface of the sun and constantly shake are actually 1 billion tons of material that are being ejected to an altitude of 300,000 kilometers, and those erected "bone needles" are higher mountains than the Himalayas.

I've seen a piece of Chang'e.

The Taidu of Bai No. 2

The masks worn by the astronauts in space are also gilded to prevent sunlight from damaging their eyes.

Turning off the atmosphere with starry sky simulation software can simulate what you see, and this is simulated with stellarium:

There is no atmosphere on Mercury, so viewing the Sun from Mercury is a "big fireball": the diameter of the Sun is about twice as large as it is on Earth. For the Mercury orbiter, the sun is something that cannot be avoided, so no image data ...... can be found

As you go beyond the Earth's orbit, the sun gets darker and darker.

On Mars, because there is also an atmosphere and dust, the Sun looks similar to that on Earth, but it is darker and smaller. The picture below is a sunset on Mars taken by Spirit:

From the point of view of mankind itself, we live in a vast and boundless land, and if it were not for scientific progress, people would not have been able to confirm that their genus actually lived on a spherical star. It was only after Magellan's fleet circled the Earth that it was widely recognized as a sphere, and it was not until the artificial Earth satellite was lifted into space that people saw the Earth for the first time. When viewed from space, the atmosphere resembles a veil, with white clouds lining the blue ocean and the green and yellow land.

The earth is a water planet, and the ocean accounts for 71% of the world's area, and it is this vast ocean that brings vitality to the earth.

It's not about putting the sun in the position of a star, because the sun itself is a star. It's about putting the sun far enough away that the sun is just a little faint star.

The Sun itself is a small mass, low-luminosity yellow dwarf star that is not very bright in itself. The Sun we see is very large and very bright because the Sun is very close to us and the other stars are very far away from us.

The brightness of a star is measured by "magnitude", and the higher the magnitude number, the darker it becomes; The lower the number, the brighter it is. There are two criteria for magnitude.

One is to see how bright the star is in the visible range at the distance where it is, which is called the "apparent magnitude" of the star. The apparent magnitude of the Sun is -26 magnitude, making it the brightest object of the day.

The other is to "place" the stars at a distance of light years (10 parsecs) and see how bright they are. This is called the "absolute magnitude" of the star. Absolute magnitude is the true brightness of a star.

The absolute magnitude of the Sun is just equal. The faintest star that the human eye can see on a night when the human eye has excellent vision, absolutely no light, and the sky is extremely clear, is about 6th magnitude, and generally only about 5th magnitude star. That is, if the Sun is at a distance of 10 parsecs, and we look at the Sun again, it is just an extremely faint little star.

No matter where you are, the sun is a star or not.
