Sunbeams: impact. Harmful sun rays. Types of solar panels and their application

Each person is unique, but the entire population of the planet Earth can be divided into two types: solar and lunar. Each of them has its own features and characteristics.

Determining the type to which you belong will help you choose the right strategy in life, achieve your goals, taking into account the characteristics of your character, and interact productively with people around you. You can also choose a life partner with whom you will be comfortable. Astrologers use this topic in order to better interpret the influence of the planets on people with different types energy. The characters of people appear already in childhood, so it will not be difficult to determine what type you or your child is.

Lunar type of people

These people can be described as quiet and shy. They prefer a passive way of life, they are not set up for active promotion, they try to stay in the shadows. They do not strive to achieve something new, and often stop at the first step of what has been achieved and try with all their might to preserve what they have received, not wanting new improvements.

Lunar type people are benevolent, extremely emotional and sensitive. They have a highly developed intuition, and they prefer to listen to the voice of the heart, not the mind. They are distinguished by self-doubt, so they often look for a person who would become their support and protector.

Children with a lunar type of energy early age capricious and whiny, less mobile than people solar type, are afraid of the unknown and do not seek to know the world in all its diversity. However, for all their shyness, they grow up to be good specialists who are well versed in their field.

Sunny type of people

Sunny people can be called the engines of progress. It is they who crave renewal and have an inquisitive mind, are in constant search of themselves. The sun gives them unbending willpower, perseverance and even aggression. The solar type of people is closely within the generally accepted framework, so they constantly strive to break out, to show themselves. They are able to make quick decisions in critical situations, bypass obstacles or overcome them, not being able to abandon the goal. The solar type of people is characterized by the spirit of dispute and competition.

FROM childhood people of the solar type show curiosity, seek to get rid of guardianship. They have a strong spirit of contradiction, so in adolescence often clashes with peers and older people. However, if such a type of people is instilled with rules of conduct and good manners from childhood, communicate with them on an equal footing and satisfy natural curiosity and inquisitiveness, they will grow up as harmonious personalities.

Unions of solar and lunar people

Both spouses belong to the solar type. In such a relationship there will be no place for comfort and harmony. All the spouses will do is fight for leadership. Such love usually does not last long, but the intensity of passions and genuine passion in them is always maintained. If the spouses fail to find the line that will help them exist in comfort, then their marriage is doomed.

Both spouses belong to the lunar type. Such marriages can be called eternal. Quiet and harmonious relationship, which proceed without outbreaks of emotions, can be described as the most successful version of married life. Spouses are tuned to the same wave and act together, not trying to prove their importance. In such families, you will not see the intensity of passions.

The husband is lunar and the wife is solar. There is no harmony in such families, and the woman takes over the reins of government. Men in such families do not have their own opinions and often find themselves in the role of "henpecked", allowing the chosen one to "command the parade" and set the tone in relationships. Such alliances are also doomed in most cases.

The husband is solar and the wife is lunar. Excessive submissiveness of a woman in such a family can lead to disastrous consequences. Patience and unwillingness to quarrel with her husband puts her in an unenviable position, and complaisance over time is perceived by a man as permissiveness. Such marriages often break up due to frequent betrayals of the spouse.

Whatever type of person you belong to, cultivate the best character traits in yourself and do not be led by emotions all the time. Moon people there is not enough assertiveness, which is more than enough for the solar type. They should start to respect themselves and train their willpower in order to resist the aggressive world. BUT sunny people On the contrary, it is necessary to learn self-control and respect the opinions of others. We wish you good luck and don't forget to press the buttons and

Each representative of the zodiac circle has its own characteristics that attract the attention of others. Knowing about them, anyone ...

A star named the Sun is the only one in our system. Other objects revolve around it, including the planet Earth, where we live. And given the incommensurable importance of this celestial body for the existence of all living things, including humans on Earth, it is also important to know what the Sun consists of and how many more years it can shine.

Sun Worship and Study

Since ancient times, people have noticed the leading role that this star plays for all living things. Many ancient cultures deified the Sun, there was a cult of worship to it. It was revered as a deity in ancient Egypt, in pre-Columbian America. And some of the greatest buildings of mankind are dedicated to the Sun: Stonehenge in England, Chichen Itza in Mexico, for example. And given the sunny location, built Pyramids of Egypt. Interestingly, the ancient Greek astronomers considered the Sun to be one of the planets, on a par with the Earth. Of course, in those days, no one guessed what the Sun consists of. So, for example, the Greek philosopher Anaxagoras considered him to be made of metal (for which, by the way, he was thrown into prison and sentenced to death). And the idea that all planets revolve around the center, which is a given star, was put forward by scientists ancient india(and almost simultaneously - Greece), but revived and developed by Copernicus already in the 16th century.

modern science

Modern science has certainly come a long way. Scientists calculated the mass of this celestial body, and its estimated volume, and the distance to the Earth. Observations are carried out visually with the help of the most powerful modern telescopes, capable of magnifying so that everything is visible at a glance. With the help of artificial satellites launched into appropriate orbits, invaluable materials are mined that contribute to a more detailed study. Now it is already known with accuracy what the Sun consists of. And also became clear to the scientists "sun scientists" and its qualitative and configurational composition.

Internal structure

Our star has a layered structure. It is worth noting that its mass is more than 99% of the total mass of the entire solar system(for comparison, this is 330,000 times the mass of the Earth). According to the spectral classification, the Sun belongs to the "yellow dwarf" type. The core is the central part where thermonuclear processes take place (radius is more than 150 thousand kilometers). There is a very high temperature - over 14 million degrees, and the substance reaches a huge density. Energy and heat in the core are produced by this reaction, and the rest of the sun's area is heated by them. What is the core of the sun made of? Since a thermonuclear reaction occurs in the center of the star, and hydrogen, which occupies the largest part in the composition, burns out, then, according to scientists, there is more helium (64%) and less hydrogen (up to 36%).

What is the sun made of

Well, that's about the core. The sun itself is mostly made up of hydrogen. Its 92% by volume, and by weight - 73%. The next element is helium (7% by volume). Other elements are also present: iron and nickel, oxygen and nitrogen, sulfur and magnesium, calcium and chromium, and some others - these are the substances the Sun consists of.

Two main layers

Two main layers can be distinguished: internal and atmospheric. The inner one consists of three parts: core, energy transfer zone, convection zone. The Sun's atmosphere consists of three parts: the photosphere, chromosphere, and corona.

Energy transfer by rays and convection

In the zone following the core, the thermonuclear energy generated by the core of the star is transferred to the upper layers of the Sun. The temperature decreases gradually, and the wavelength increases. This segment occupies from 0.3 to 0.7 of the total radius from the center. The convective zone, located next, carries out the transfer of energy through the process of convection.

Atmosphere of the Sun

The photosphere is the visible surface of the Sun. It sends spectral rays into the surrounding space. Its thickness is only 200 kilometers. And above it is a layer of the chromosphere, which has a thickness many times greater - up to 20,000 kilometers. Gases are constantly rising and falling there, carrying out movement. Prominences sometimes appear in the chromosphere, protruding beyond the surface up to 250,000 kilometers, visible even from Earth. Sometimes the matter collected in the prominence overcomes the solar attraction and breaks off into outer space. as if completing the construction of the Sun itself, rising to 2 million kilometers. The appearance of the corona is not always the same and is associated with the periods of activity of the star.

sunny wind

From the corona constantly follows a stream of particles that are ionized. These are mostly protons and electrons, called the solar wind. They extend to the very limits of the solar atmosphere. The radiation reaches a myriad of particles per second. And their loss for a yellow dwarf is, over millions of years, a mass equivalent to the mass of such a planet as, for example, the Earth. Phenomena such as or on Earth are directly related to the impact of the solar wind.

Sun and life on earth

For people, animals and plants that live on Earth, the Sun and the light it emits is an extremely important thing. In those places where the rays fall in a limited amount, a small variety of biological forms, a shortening of the growing season for plants, and a short stature of species have been noticed. Sunlight is the basis for photosynthesis. And the chlorophyll contained in the leaves of plants is one of the main conditions for the emergence of life on Earth, according to most scientists. And many species of animals (and humans) exist by eating plants and accumulating solar energy in organisms. Another important factor for the existence of all living things is ultraviolet radiation The sun, with the help of which vitamin D is produced. But it protects our planet from excessive ultraviolet radiation, without which, according to researchers, life forms would not be able to get out on land from the waters of the World Ocean.

Explaining what the Sun consists of is not difficult for children. But in order to understand the structural features of a huge star such as this one, it is necessary to imagine the infinite amount of gas that is concentrated in one place in the solar system. And to put it simply, the Sun consists, for the most part, of both hydrogen and helium. These gases are very light, but the star itself is very heavy and weighs like 330,000 planets identical to the Earth. And the temperature to which these and other elements that make up the composition are heated reaches up to 15 million degrees. Many data on the composition of a star by modern scientists were obtained using the sunlight, which reaches the Earth, and are quite accurate.

Consider what characteristics a pure type of Sun has. The skull of the solar types, like the Mercury ones, is dolichocephalic, i.e., long-headed. The face is oval. This oval is very clean and beautiful. The hair is beautiful, blond or chestnut, elegantly covering the head and slightly curly.

What do people look like whose type according to the horoscope is the Sun

  • Sun type temples are usually bare.
  • Often they are bald - to a greater or lesser extent.
  • A solar face radiates balance, harmony and calm strength.
  • The forehead is large and splendidly intellectualized. It is convex, both across and in length - from top to bottom: the frontal bones, protruding upwards, are well developed. This forehead differs sharply from the flat foreheads of Mars, Earth and Mercury. It is most similar to the forehead of a Venusian: there is not a single wrinkle that would betray overwork, nervousness and effort, the skin is surprisingly smooth. Martian and terrestrial types frown their foreheads, expressing desire. The sun desires quite naturally, without wincing or frowning - its autocracy is so full. The sun forehead is the most beautiful of all types.
  • Aristocratically graceful, but thick enough, eyebrows express energy even in calm state. They don't need to frown.
  • The eyes are large, open, with beautiful eyelashes. They look directly, honestly, without threat, without coercive force, but not weakly, they look at you magnetically. The iris, almost completely closed by the eyelids, is dotted with golden spots. The nose of the solar type harmonizes well with his convex forehead - it is slightly "pointed" and refined in the upper part.

Pure type Sun. The lips are beautiful: not too big and not too small. The upper lip is well defined (it is very different from the straight and flat upper lip Mercury). Underlip commensurate with the top.

The folds at the tips of the lips do not express either contempt, as is often the case with Mercurians, or pessimism (as with Saturnians), or effort (as with Mars and Earth). They speak of dignity, self-control, calmness, kindness. The smile of the solar type is sober and kind.

The chin confirms and emphasizes the balance that the lips express: it is not as short and square as in the Martian and Earth types, and not as elongated as in the Mercurian. Square, but at the same time forms part of an oval face.

The nature of the representatives of the Sun

Solar types are surprisingly calm and strong. The word that best expresses their state of mind is unclouded clarity (serenite). The solar type radiates complete self-control, happiness, strength. He evokes admiration mixed with fear in those around him.

The solar type is an expression of wondrous harmony. He could use his energy, but saves it. “He represents strength at rest, self-confident strength, which does not manifest itself unnecessarily, because it knows that at the first call it will immediately, in one leap, rise to its feet, ready to flash like lightning” (Victor Morgan).

In the eyes of the solar type, unshakable energy is read, associated with captivating meekness. With just one look, these eyes amaze or heal.

Who are the representatives of the pure type of the Sun

Pure type Sun. Speech of the solar type is sonorous and fluttering with a clear timbre. She knows how to conquer, throw thunder, forgive. Solar types can become scientists in all branches of human knowledge.

Among them are born major organizers, industrialists, bankers, leaders. Their superiority over others is the reason why they find it difficult to find a friend in love. The solar type of men suffers from female pettiness. A woman of the solar type, noble, with a developed mind, is looking in vain for a man who will surpass her.

The fact that without the Sun life on Earth would not exist, people understood a long time ago, because he was exalted, he was worshiped, and celebrating the day of the Sun, they often made human sacrifices. They watched him and, creating observatories, solved such seemingly simple questions about why the Sun shines during the day, what is the nature of the luminary, when the Sun sets, where does it rise, what objects are around the Sun, and planned their activities on the basis of the received data.

Scientists had no idea that on the only star in the solar system there are seasons that are very reminiscent of the "rainy season" and "dry season". The activity of the Sun alternately increases in the northern and southern hemispheres, lasts eleven months, and decreases for the same amount of time. Along with the eleven-year cycle of its activity, the life of earthlings directly depends, since at this time powerful magnetic fields are ejected from the bowels of the star, causing solar disturbances that are dangerous for the planet.

It may surprise some to learn that the Sun is not a planet. The sun is a huge, luminous ball of gases, inside which thermonuclear reactions are constantly taking place, releasing energy, giving light and heat. It is interesting that such a star does not exist in the solar system, and therefore it attracts to itself all smaller objects that are in its gravitational zone, as a result of which they begin to rotate around the Sun along a trajectory.

Naturally, in space, the solar system is not located on its own, but is part of the Milky Way, a galaxy that is a huge star system. From the center of the Milky Way, the Sun is separated by 26 thousand light years, so the movement of the Sun around it is one revolution in 200 million years. But the star turns around its axis in a month - and then, these data are approximate: it is a plasma ball, the components of which rotate at different speeds, and therefore it is difficult to say exactly how much time it takes to complete a revolution. So, for example, in the equator region this happens in 25 days, at the poles - 11 days more.

Of all the stars known today, our Luminary is in fourth place in terms of brightness (when a star shows solar activity, it shines brighter than when it subsides). By itself, this huge gaseous ball is white, but due to the fact that our atmosphere absorbs short-spectrum waves and the Sun's ray is scattered near the Earth's surface, the Sun's light becomes yellowish, and White color can only be seen on a clear, fine day against a blue sky.

Being the only star in the solar system, the Sun is also the only source of its light (not counting the very distant stars). Despite the fact that the Sun and Moon are the largest and brightest objects in the sky of our planet, the difference between them is huge. While the Sun itself emits light, the Earth's satellite, being an absolutely dark object, simply reflects it (we can also say that we also see the Sun at night, when the Moon illuminated by it is in the sky).

The sun shone - a young star, its age, according to scientists, is more than four and a half billion years. Therefore, it refers to a third generation star, which was formed from the remains of pre-existing stars. It is rightfully considered the largest object in the solar system, since its weight is 743 times the mass of all the planets revolving around the sun (our planet is 333 thousand times lighter than the sun and 109 times smaller than it).

Atmosphere of the Sun

Since the temperature indicators of the upper layers of the Sun exceed 6 thousand degrees Celsius, it solid body is not: with such high temperature any stone or metal is transformed into gas. Scientists have come to such conclusions recently, because earlier astronomers suggested that the light and heat emitted by the star are the result of combustion.

The more astronomers watched the Sun, the clearer it became: its surface has been heated to the limit for several billion years, and nothing can burn for so long. According to one of the modern hypotheses, the same processes take place inside the Sun as in atomic bomb- matter is converted into energy, and as a result of thermonuclear reactions, hydrogen (its share in the composition of the star is about 73.5%) is transformed into helium (almost 25%).

Rumors that the Sun on Earth will go out sooner or later are not unfounded: the amount of hydrogen in the core is not unlimited. As it burns, the outer layer of the star will expand, while the core, on the contrary, will decrease, as a result of which the life of the Sun will end, and it will be transformed into a nebula. This process will start soon. According to scientists, this will happen no earlier than in five to six billion years.

As for the internal structure, since the star is a gaseous ball, it is united with the planet only by the presence of a core.

Core

It is here that all thermonuclear reactions take place, generating heat and energy, which, bypassing all subsequent layers of the Sun, leave it in the form of sunlight and kinetic energy. The solar core extends from the center of the sun to a distance of 173,000 km (approximately 0.2 solar radii). It is interesting that in the core the star rotates around its axis much faster than in the upper layers.

Radiant transfer zone

Photons leaving the nucleus in the radiative transfer zone collide with plasma particles (ionized gas formed from neutral atoms and charged particles, ions and electrons) and exchange energy with them. There are so many collisions that a photon sometimes takes about a million years to pass this layer, and this despite the fact that the plasma density and its temperature indicators outer border decrease.

tachocline

Between the radiative transfer zone and the convective zone there is a very thin layer where the formation of magnetic fieldlines of force electromagnetic field are pulled out by plasma streams, increasing its intensity. There is every reason to believe that here the plasma significantly changes its structure.


convective zone

Near the solar surface, the temperature and density of matter becomes insufficient for the energy of the Sun to be transferred only with the help of reradiation. Therefore, here the plasma begins to rotate, forming vortices, transferring energy to the surface, while the closer to the outer edge of the zone, the more it cools, and the gas density decreases. At the same time, the particles of the photosphere located above it, cooled on the surface, go into the convective zone.

Photosphere

The photosphere is called the brightest part of the Sun, which can be seen from the Earth in the form of the solar surface (it is called so conventionally, since a body consisting of gas does not have a surface, therefore it is referred to as part of the atmosphere).

Compared with the radius of a star (700 thousand km), the photosphere is a very thin layer with a thickness of 100 to 400 km.

It is here that during the manifestation of solar activity, the release of light, kinetic and thermal energy occurs. Since the temperature of the plasma in the photosphere is lower than in other places, and there is strong magnetic radiation, sunspots are formed in it, giving rise to the well-known phenomenon as solar flares.


Although solar flares are short-lived, an extremely large amount of energy is released during this period. And it manifests itself in the form of charged particles, ultraviolet, optical, X-ray or gamma radiation, as well as plasma flows (on our planet they cause magnetic storms that negatively affect people's health).

The gas in this part of the star is relatively rarefied and rotates very unevenly: its revolution around the equator is 24 days, at the poles - thirty. In the upper layers of the photosphere, minimum temperature indicators were recorded, due to which out of 10 thousand hydrogen atoms only one has a charged ion (despite this, even in this region the plasma is quite ionized).

Chromosphere

The chromosphere is called the upper shell of the Sun with a thickness of 2 thousand km. In this layer, the temperature rises sharply, and hydrogen and other substances begin to actively ionize. The density of this part of the Sun is usually low, and therefore it is difficult to distinguish from the Earth, and it can be seen only in the event of an eclipse of the Sun, when the Moon covers the brighter layer of the photosphere (the chromosphere glows red at this time).

Crown

The corona is the last outer, very hot shell of the Sun, which is visible from our planet during the total solar eclipse: it resembles a radiant halo. At other times, it is impossible to see it because of the very low density and brightness.


It consists of prominences, hot gas fountains up to 40,000 km high, and energy eruptions that go into space at great speed, forming a solar wind consisting of a stream of charged particles. Interestingly, it is with the solar wind that many natural phenomena our planet, for example, the northern lights. It should be noted that the solar wind itself is extremely dangerous, and if our planet was not protected by the atmosphere, then it would destroy all life.

earth year

Our planet moves around the Sun at a speed of about 30 km / s and the period of its complete revolution is one year (the length of the orbit is more than 930 million km). At the point where the solar disk is closest to the Earth, our planet is separated from the star by 147 million km, and at the most distant point - 152 million km.

The "motion of the Sun" seen from the Earth changes throughout the whole year, and its trajectory resembles a figure eight stretched along the Earth's axis from north to south with a slope of forty-seven degrees.

This happens due to the fact that the angle of deviation of the Earth's axis from the perpendicular to the plane of the orbit is about 23.5 degrees, and since our planet revolves around the Sun, the rays of the Sun daily and hourly (not counting the equator, where day is equal to night) change the angle of their fall at the same point.

In the summer in the northern hemisphere, our planet is tilted towards the Sun, and therefore the rays of the Sun illuminate earth's surface maximally intense. But in winter, since the path of the solar disk through the sky is very low, the Sun's ray falls on our planet at a steeper angle, and therefore the earth warms up weakly.


The average temperature is set when autumn or spring arrives and the Sun is at the same distance from the poles. At this time, nights and days are approximately the same length - and Earth creates climatic conditions, which is a transitional stage between winter and summer.

Such changes begin to take place even in winter, after the winter solstice, when the trajectory of the Sun's movement across the sky changes, and it begins to rise.

Therefore, when spring comes, the Sun approaches the day of the vernal equinox, the length of day and night becomes the same. In the summer, June 21, on the day of the summer solstice, the solar disk reaches its highest point above the horizon.

earth day

If you look at the sky from the point of view of an earthling in search of an answer to the question of why the Sun shines during the day and where it rises, then you can soon make sure that the Sun rises in the east, and its setting can be seen in the west.

This happens due to the fact that our planet not only moves around the Sun, but also rotates around its axis, making a complete revolution in 24 hours. If you look at the Earth from space, you can see that it, like most of the planets of the Sun, turns counterclockwise, from west to east. Standing on Earth and watching where the Sun appears in the morning, everything is seen in a mirror image, and therefore the Sun rises in the east.

At the same time, an interesting picture is observed: a person, observing where the Sun is, standing at one point, moves along with the Earth in eastbound. At the same time, the parts of the planet that are located in the western side, one after another, gradually begin to illuminate the light of the Sun. So. for example, sunrise on the east coast of the United States can be seen up to three hours before the sun rises on the west coast.

The sun in the life of the earth

The Sun and the Earth are so connected with each other that the role of the largest star in the sky can hardly be overestimated. First of all, our planet formed around the Sun and life appeared. Also, the energy of the Sun warms the Earth, the ray of the Sun illuminates it, forming a climate, cooling it at night, and after the Sun rises, it warms it again. What can I say, even the air with its help acquired the properties necessary for life (if not a ray of the Sun, it would be a liquid ocean of nitrogen surrounding blocks of ice and frozen land).

The Sun and the Moon, being the largest objects in the sky, actively interacting with each other, not only illuminate the Earth, but also directly affect the movement of our planet - a prime example of this action are the ebb and flow. They are influenced by the Moon, the Sun in this process is on the sidelines, but without its influence it also cannot do.

The sun and the moon, the earth and the sun, air and water flows, the biomass that surrounds us are available, constantly renewable energy raw materials that can be easily used (it lies on the surface, it does not need to be extracted from the bowels of the planet, it does not form radioactive and toxic waste ).

To draw public attention to the possibility of using renewable energy sources, since the mid-90s. last century, it was decided to celebrate the International Day of the Sun. Thus, every year, on May 3, on the day of the Sun, seminars, exhibitions, conferences are held throughout Europe aimed at showing people how to use the ray of the luminary for good, how to determine the time when the sunset or sunrise occurs.

For example, on the day of the Sun, you can visit special multimedia programs, see huge areas of magnetic disturbances and various manifestations of solar activity through a telescope. On the day of the Sun, you can look at various physical experiments and demonstrations that clearly demonstrate how powerful a source of energy our Luminary is. Often on the Day of the Sun, visitors get the opportunity to create a sundial and test it in action.
