There is enough solar heat and light for all living beings on Earth, despite the fact that the Sun is at a distance of almost 150,000,000 km from us, and if suddenly our Sun went out, stopped shining and warming, it would become so cold that the whole water on Earth, even the air would freeze. People, animals, plants would die. Our planet would become cold and dead.
The temperature on the surface of the Sun is about 6 OOPS. At such a high temperature, iron and other metals not only melt, but turn into hot gases.
Therefore, there are neither solid nor liquid substances on the Sun: there is only hot gas. The sun is a huge hot ball of gas. The temperature inside the Sun is even higher than on its surface. Near the center of the ball, it reaches 15 million degrees. Such a high temperature inside the Sun has existed for several billion years and will continue to exist for about the same.
What happens inside the sun? Why doesn't this giant fire go out? Astronomers and physicists have been pondering the question for a long time: how is a very high temperature maintained inside the Sun for billions of years?
Most scientists believe that inside the Sun chemical element hydrogen is converted into another chemical element helium. Particles of hydrogen combine into heavier particles, with this combination, energy is released in the form of light and heat, which is scattered by the Sun in outer space and comes to Earth to give life to all living things.

Interpretation of dreams from the Noble dream bookAll human life on earth is subject to the sun.
The religions of the ancient peoples placed the sun at the center of the universe.
Therefore, the sun has firmly entered the unconscious area of \u200b\u200bman, as the main symbol.
Even the first soothsayers and dream interpreters noticed that the appearance of the sun in a dream portends success, honors.
And all other dream events taking place against the backdrop of a sunny day carry favorable news.
Modern people are more remote from nature than primitive tribes.
But at the level of unconscious feelings, we all have a mystical participation with nature.
Highest success, ardor in the implementation of the project, pleasure from life situation.
It symbolizes spiritual activity, ardor in the implementation of the project.
To see the sun in a dream is to have pleasure in a life situation, a bright mind.
It is symbolically depicted by various round figures: a disk, a wheel, a circle with a dot in the center.
These figures seen in a dream can also be correlated with the sun.
Very often in a dream we do not see the sun as a whole, but only sunlight.
Otherwise, just a beam of light.
This is the personification of a force capable of dispersing evil and darkness.
In a more modern sense, a ray of light is concrete, analytical knowledge.
And it is known that knowledge in a dream is a preemptive, prophetic knowledge.
Therefore, one should with special confidence relate to the events of a dream illuminated by sunlight.

“With excitement, we looked through twelve more plates ... and on four of them we found the same object, no doubt - a new comet, since at close exposures its movement relative to the stars was noticeable. After reviewing all the catalogs and ephemeris for 1969 on comet circulars, it was found that the comet is really new and we are holding ...
Deserts can be classified in different ways: By climatic zones: polar - Antarctica, Greenland, the coast and islands of the Arctic; temperate climate, cold and warm - in the Central and Central Asia, in North America and Patagonia; and, finally, subtropical hot ones - Sahara, deserts of Australia, Hindustan, Pacific coast South America. According to the composition of the soil: sandy (ergs), sandy-gravelly, gravel-gypsum (serir, reg), stony (gam-mada, ...

Greenland is the largest and one of the oldest islands in the world. Its northern tip, located above 85 degrees north latitude, is located at a distance of about 700 kilometers from the North Pole, and its southern tip is at the sixtieth parallel, that is, approximately at the same latitude as St. Petersburg. The length of the island is about 2,700 kilometers. Greenland is almost entirely covered in ice, which…
Why does the starry sky seem to be rotating, and why exactly is the North Star almost motionless? It turns out that the reason for this apparent movement of the stars is the rotation of the Earth. Just as a person whirling around the room imagines that the whole room is spinning around him, so we, who are on the rotating Earth, see as if moving stars. Our Earth has an axis of rotation...

In astronomy, a satellite is a body that revolves around a larger body and is held by its force of attraction. The Moon is the Earth's satellite. Earth is a satellite of the Sun. All planets solar system, with the exception of Mercury and Venus, have satellites. Artificial satellites are man-made spacecraft that orbit the Earth or another planet. They are launched for various purposes: ...
Precise measurements show that the diameter of the Sun is not constant. A few years ago, astronomers discovered that the volume of the sun decreases and increases by several kilometers every 2 hours and 40 minutes, and this period remains strictly constant. With a period of 2 hours 40 minutes, the luminosity of the Sun also changes, i.e. the energy they radiate. Such changes in the volume of the Sun are called radial pulsations….
Even in ancient times, observers noticed that in the sky, in addition to fixed stars there are special wandering luminaries, and they called them planets (planet in Greek means wandering). At first glance, the planet and the star are really very similar. But if you look closely, you can see that the stars twinkle, and the planets shine with an even, calm light. This happens because…
The sun is the main source of life on planet Earth. It is the closest star to us. Others are so far away that their light only reaches us millions of light years away. And if the Sun stops radiating its energy, all life on the Planet will definitely die.
Surely each of us at least once asked the question: “Why, in fact, in the summer from the sunlight we sunbathe, and in the winter the same light is not even able to melt the ice a little?” So, let's figure it out.
How the sun works
Studying the Sun is a very difficult task. It is impossible to send aircraft to him, as they will simply burn out. But modern science there are many other ways to study an object that is far away, but radiates colossal energy at the same time. The distance to the Sun from Earth is 150 million km. It is this distance that allows life on our planet to exist comfortably.
In diameter, the core of the Sun reaches 175 thousand kilometers. The temperature inside the star is 14 million degrees Kelvin, and its causes are thermonuclear reactions. We can say that this is a kind of nuclear furnace. All the heat is generated in the core of the star, which then passes through several shells:
- the photosphere is the first layer above the nucleus, but the energy of the deeper layers does not reach here;
- spicules are regular ejections from the next layer of the Sun;
- The crown is the outermost shell of a star.
Visible light and solar energy are infrared rays and ultraviolet, as well as electromagnetic waves, radiation and x-rays.
Important! All these waves reach the Earth and other planets of the solar system and in a certain way affect them, and especially those of them where there is an atmosphere.
Influence of rays
All living things are affected primarily by UV rays. It is from their intensity ozone layer protecting our planet. The effect of ultraviolet rays on living organisms is manifested in the following:
- they contribute to the metabolic processes in the human body;
- thanks to this radiation, vitamin D is produced in the body, and without it a normal human life is impossible;
- increased blood flow;
- tan appears.
UV rays also have a positive effect on the atmosphere. They purify it and make it more favorable for life. Infrared rays also have a thermal effect. Thanks to them, the surface of the Earth is warm. But although these rays affect the atmosphere, there are times when their influence becomes minimal.
In winter, the sun heats less
In winter, the Sun heats less intensely, but this phenomenon can be explained with scientific point vision. There is a decrease in the flow of solar heat to the Earth for the following reasons:
- the sun is very low above the horizon, so the rays travel a longer distance through the atmosphere;
- in the morning and in the evening, for the same reason, it is not so hot, but in the evening it gets cold;
- cold wind shortens the period of heat that the sun can give us;
- In winter, the days are shorter and the nights are longer, which means that the period when infrared rays can affect the atmosphere is greatly reduced.
As we can see, although the Sun shines in winter, it is not necessary to expect a tan from it.
