The story of a star

The magnificent night sky is so impressive that the night sky is so delightful to be seen from the stars. There is a waste of life. But compared to our lifetime, the age of the stars is very large.

Generally, the life span of a star is estimated to be billions, millions of. There are also births and deaths for those stars. So let's look at the story of this astounding star.

What is a star? Simply stated, a star is a self-propagating celestial vehicle carrying out chemical reactions. A star is massive and mass with a mass. Our sun is also a similar star. In our Milky Way galaxy, hundreds or thousands of stars are large and small. A very large number of stars are in the Milky Way, but all stars can not be named. There are many bright and large stars named. The temperature, mass, radius, density, spectrum, absolute optical size, and brightness are some of the few steps to classify the star. Astronomers can elaborate on the basis of these dimensions by describing the nature of the stars and the evolution of the stars based on mathematical principles. A star has two important forces in the study of evolution: the inner gravity of the star is compressed by gravity, and the extrusion of the star due to internal exit. Let's examine in detail the evolution of the star.

You have probably heard that a star begins his life by cluttering a massive dust cloud. These gases are called an interstellar medium. This gas is also called Molecavala. The molecular moon is comprised of hydrogen, helium, and nitrogen, oxygen, carbon, calcium, sodium, iron, and silicate. These dust particles are very cold at an early stage, and when the gas is in contact with the particles contained in the cloud, its temperature rises rapidly. The same temperature is about 150,000 Kelvin (K). Due to the interaction of these dirty particles, the region starts flashing brightly. At that time, a star is known as the pre-star Prota Star. This Prague star appears as a new star. The brightness of the primord exceeds the brightness of the sun. During this period, its surface temperature remains unchanged. At this time, the surface of the surface of the nucleus remains at odds. The nuclear fusion collides with the nucleus, causing the velocity (K) of the prologue to increase to about 15,000,000. When particles are moving. Here the gravitational contraction of the star gradually decreases. The elements of lithium, beryllium, and boron react with protons. As a result, helium is formed, and hydrogen begins to burn. This causes a lot of energy to be released into the space. This helium, carbon, oxygen, etc. is then a separate element. These reactions are going on for a very long time. This reactions cause a reaction that does not react to reactions. The star begins to collapse. The star is cooled and the star is applied reddish. The crust of the crust, or the front cover, becomes a red giant. Here, some of the stars split the starry stars superiino. Finally, if the remaining core is huge, it could become a black hole. The evolution of a thermometer is, by the way, yes.

How to evolve a star

It has been mentioned earlier that a star begins to live by a molecular moon. In the Milky Way, there are a very large number of such molecules in the Milky Way. Such media are a large number of light-emitting diodes. The Oryan Nebula (M42) can be seen in the night sky. There are many newborn stars in the Orion Nebula. The above-mentioned Prague stars, mentioned above, are aroused by the stirring of the same kind of media. The internal temperature of Prague is also known as the primary star of the star until 10000 ℃. The significance of the stars in this era is that there is a molecular cloud around the star. It's easy to see such stars. But when this young star climbs to a young stage, it behaves violently. The temperature of the star increases by a thousand degrees Celsius. Because of the reactions, the star releases a lot of energy from the star, and this energy causes the star around the star to breathe in the air. The molecular cloud around the star is scattered from the star. What is remarkable is that this is how the solar system developed. The octave clouds originate from the Oregon owl, which is about 1.5 light-years away, from planets to planetary stars. The planets travel around the planet, affecting each other's gravity power. The "dust" plate is used as a transit point for the stars to travel around the star. More than 150 of these Prague stars have been found in the Orion Nebula. Scientists doubt that Prague is surrounded by Prague. If we talk about the inner part of Prague, 99% of the gases and 1% of the dust particles are contained.

In this instance, Prague star moves to a young stage. Our sun is also a young star. This youngster star has been in existence for billions of years until all the combustion of hydrogen is complete. At this time, the star produces maximum energy. Here, the hydrogen molecule is converted to hydrogen by reacting hydrogen nuclear fusion. This makes a bright star. This youngster star represents the major sequence of the stars classification scheme called Hertz spang Russell -HR. According to this figure, a star is added based on the type of star, temperature, optical brightness, absolute brightness, and spectrum. The following HR comments can be understood about the above.

You see that our sun is located at the center of the main initiation of this chart. It makes it clear that our sun is still young. And our sun goes down in the main sequence of billions for billions of years .The star disappears after the nuclear star is turned into hydrogen helium by expending its strength. The star retires from the main section of the HR chart. It can be explained as follows. Then the star's destiny is determined by the mass of the star.

Awakenings like our Sun's mass evolve into a reddish star after their young age. The outer layer of the star is expanding. In the same way, our Sun will expand and become explosive. This sparkling spoon is spread to the universe. This outer crust becomes a nebulizer. In the center of this planet, the small star becomes a white dwarf. The cat eye nebula, the Helix Nebula, is a number of such disorders.

Helix Nebula

Also, when we reduce the mass of the Sun, which is about half the mass of the Sun, the young star becomes a dark, black-and-white star, and finishes the star's life.

The more massive stars we starve than the sun to their youthful age and the red giant star, then expands a star more than the size of a star equal to that of the sun. The explosion is known as the supernova, which releases an invisible force to the universe. The Crab Nebula (the Crab Nebula) in the wild is a great example of this supernova explosion. Where the star remains in 

  Night sky

It is no secret that the night sky is a magnificent sight as well as a curious space filled with science. So let's look at the night in which we can observe this night.

There is a large number of observations in the night sky. Stars, planets, moon, comet, meteorites, meteor shower, star clusters, star clusters, nibulae, galaxies, artificial satellites, sub-planets.

Objects that can be observed by the naked eye without a telescope.

1. Planets

Mercury, Venus, Mars, Jupiter, Saturn

2. Gelatinous

Eg, the Andromeda galaxy, the Milky Way

3. Nebas

Eg - OrionNebula

4. Star clusters

Eg - to make the stars happy

5. Moon, precursors, meteors, satellites, stars, constellations of constellations

But for further study of these objects, a telescope should be used. Specifically, when there are galaxies in the night sky, all the stars that we see are of the Milky Way galaxy we own.

Star constriction

As you have heard, a number of stars can be thought of only as a kind of object or object of stars. But in fact, according to the definition of the International Astronomical Union, a number of stars are "one area in which the asterisks are internationally recognized with definite boundaries. "These stars, of course, have different shapes. Also, there are different size constellations with different numbers.

The ancients had a night sky of 48 constellations. Later, in 1928, the International Astronomical Union added more than 40 stars to the number of constellations.

The relation between the sky of the stars and the motion of the earth

When observing the sky in the night sky, the constellations of the constellations were lowered from the west. For this reason, the ancients thought that the earth's constellation is rotating around the earth according to aquaculture. But it does happen because the planet revolves around its axis. Especially, our country, a cohesive country, can clearly see the incident.

By carefully observing the sky with the night time, the constellation of the constellation of the constellation of the zodiac will enable us to observe the constellations of the stars except in the same time as the sun and its vicinity. However, when observing the moon for several months, the number of stars in the same location is different from time to time in different months at different times.

For example, if you observe the cluster of stars in the eastern horizon at 9 pm, and then go back about a month later at 9 o'clock at 9 pm, if you observe the magnitude of the eastern horizon, you will see dozens of stars that we saw a month ago and many other stars. Also, a month before the horizon of the eastern horizon, the constellation of the constellations in the eastern horizon. This event is a phenomenon that occurs around the sun around the sun. As the planet moves around the sun, this is how the new constellations of the stars gradually appear from time to time. This is a testimony to the fact that this solar center is correct.

If you observe the sky with such a night and night, you will be able to clearly understand the Earth's spin and revolution and the constellation of the earth.

In this case, the celestial object is called the Phenomenon-Daily Motion, on the one day in the East, at the same time descending from the west. This is due to the earth rotation (circling around itself). At the same time, at the same time, in the positioning of different constellations of the number of stars (star) during the same period, the phenomenon of change is called -actical- motion. This is because of the Earth's renaissance.

Preparation for observation

1. To find a suitable place for observation, Most of the heavens that do not interfere with the surrounding trees should be a place of light (free from light pollution) that is visible outside light. And it must be a place of injuries such as insects, snakes, thornbushes.

2. Before doing this, observe the equipment, paper, pencil, star maps, and prepare the red light torch.

Getting to the dark

Before a good observation encounter begins, darkness must be acclimatized. It takes about 15 to 20 minutes to reach the darkness from the light and darkness. When we are in the dark, the earthing hole reduces the light entering the eye's eye. But when it comes to darkness, the aperture is enlarged and the eye tries to insert more light. Further, the sensitivity of the sensitivity to the sensitivity of the sensitivity to the light is increased, and the sensitivity to the asbestosis increases. That's why it takes about 20 minutes to adapt to the darkness. In this case, the eye gets blue, yellow and green, except for the red color, which immediately accursed to the light. This is because the blind eye is more sensitive to those colors. This blue color is the highest sensitivity. Here again, it takes 15 to 20 minutes to get familiar with the darkness of the eye. Therefore, such colors should not be used when observing. In the dark, however, the eye is less sensitive to light. Therefore, when the night sky observes, light should be used when we use red light. The darkened eye can not escape it.

For the first time, when watching the night sky, you do not need to use the star map. Firstly, what we do in the night sky should be tried with a star-studded eye without a star map. The telescope is used by telescopes for successful observations
