How far are the stars from us? School encyclopedia The fate of the most distant star

Each star system has clearly defined boundaries of the energy cocoon in which it is located. Our solar system works exactly the same way. The entire starry sky that we observe on the border of this cocoon is a holographic projection of exactly the same star systems located in our 3-dimensional space. Picture of each star system in our firmament has strictly individual parameters.

They are transmitted constantly and endlessly. The source of transmission and storage of information in space is absolutely pure and original light. It does not contain a single atom or photon of an impurity that distorts its purity. Because of this, endless myriads of stars are available to us for contemplation. All star systems have their strictly specified coordinates, written in the code of the primordial light.

The principle of operation is similar to the transmission of signals over a fiber optic cable, only with the help of coded-light information. Each star system has its own code, with the help of which it receives a personal dedicated channel for transmitting and receiving information in the form of atoms and photons of light. This is the light in which all the information emanating from the original source is contained. It has all its characteristics and qualities, as it is its integral part.

Star systems in our space have two entry-exit points for transmitting and receiving light information about themselves and about the planets located in their gravitational zone.

(Fig. 1)
Passing through the energy channels, through the gateway points (white balls in Fig. 2), their light and information about them enters the zone of comparison and decoding of the orientation matrix. As a result of this, the light information already processed inside the stars at the atomic level is relayed further into our space, in the form of a finished holographic image. The figure showed how information enters the Sun through light channels, after which it is relayed in the form of a holographic image of all star systems at the borders of the energy cocoon.


(Fig. 2)
The fewer gateway points between star systems, the further they are spaced from the entry-exit channel in our sky.

The codes of star systems cannot yet be expressed with the help of existing terrestrial technologies. Because of this, we have an absolutely wrong and distorted idea of ​​the galaxy, the universe and the cosmos as a whole.
We consider the cosmos to be an endless abyss, flying in different directions after the explosion. BRED, BRED AND AGAIN BRED.
The cosmos and our 3-dimensional space are very compact. It's hard to believe, but even harder to imagine. The main reason why we are not aware of this is due to a distorted perception of what we see in the firmament.
The infinity and depth of the cosmos that we observe now should be perceived as an image in a cinema, and nothing more. We always see only a flat image, relayed to the boundaries of our solar system. (See Fig. 1) Such a picture of events is not objective at all, and it completely distorts the real structure and structure of the cosmos as a whole.

The main purpose of this entire system is to visually receive information from a holographically relayed image, read atomic-light codes, decode them and further enable physical movement between stars along light channels. (See Fig. 3) Earthlings do not yet have these technologies .

Any star system can be located from each other at a distance not exceeding its own diameter, which will be equal to the distance between the gateway points + the radius of the neighboring star system. The figure roughly showed how the cosmos works if you look at it from the side, and not from the inside, as we are used to seeing it.


(Fig. 3)
Here's an example for you. The diameter of our solar system, according to our own scientists, is about 1921.56 AU. This means that the nearest star systems to us will be located at a distance of this radius, i.e. 960.78 AU + the radius of the neighboring star system to the common gateway point. You feel how in fact everything is very compact and rationally arranged. Everything is much closer than we can imagine.

Now catch the difference in numbers. The nearest star to us according to existing technologies for calculating distances is Alpha Centauri. The distance to it was determined as 15,000 ± 700 AU. e. against 960.78 AU + half the diameter of the star system Alpha Centauri itself. In terms of numbers, they were wrong by 15.625 times. Isn't it too much? After all, these are completely different orders of distances that do not reflect objective reality.

How do they do it, I do not understand at all? Measure the distance to an object using a holographic image located on the screen of a huge cinema. Just tin!!! In addition to a sad smile, this personally does not cause anything else for me.

This is how a delusional, unreliable, absolutely erroneous view of the cosmos and the entire universe as a whole develops.

At the edge of the galaxy

The most distant space objects are located so far from Earth that even light years is a ridiculously small measure of their remoteness. For example, the closest cosmic body to us - the Moon is located only 1.28 light seconds from us. How can one imagine the distances that a light pulse cannot overcome in hundreds of thousands of years? There is an opinion that it is incorrect to measure such a colossal space with classical quantities, on the other hand, we have no others.

The most distant star of our Galaxy is located in the direction of the constellation Libra and is removed from the Earth at a distance that light can overcome in 400 thousand years. It is clear that this star is located near the boundary line, in the so-called zone of the galactic halo. After all, the distance to this star is approximately 4 times the diameter of the imaginary expanses of our Galaxy. (Diameter Milky Way estimated at about 100,000 light years.)

beyond the galaxy

It is surprising that the most distant, quite bright star discovered only in our time, although it was observed earlier. For incomprehensible reasons, astronomers did not pay attention special attention on a faintly luminous spot in the starry sky and different on a photographic plate. What happens? People see a star for a quarter of a century and ... do not notice it. More recently, American astronomers from the Lowell Observatory discovered another of the most distant stars in the peripheral limits of our Galaxy.

This star, already dimmed from "old age", can be searched in the sky in the location of the constellation Virgo, at a distance of about 160 thousand light years. Such discoveries in the dark (in the literal and figurative sense of the word) parts of the Milky Way make it possible to make important adjustments in determining the true values ​​​​of the mass and size of our star system in the direction of their significant increase.

However, even the most distant stars in our galaxy are relatively close. The most distant quasars known to science are more than 30 times further away.

A quasar (English quasar - short for QUASi stellAR radio source - “quasi-stellar radio source”) is a class of extragalactic objects characterized by very high luminosity and such a small angular size that for several years after discovery they could not be distinguished from “point sources” - stars.

Not so long ago, American astronomers discovered three quasars, which are among the "oldest" objects in the universe known to science. Their distance from our planet is more than 13 billion light years. Distances to distant space formations are determined using the so-called "red shift" - a shift in the emission spectrum of fast moving objects. The farther they are from the Earth, the faster, in accordance with modern cosmological theories, they move away from our planet. The previous distance record was set in 2001. The redshift of the then discovered quasar was estimated at 6.28. The current trinity has offsets of 6.4, 6.2 and 6.1.

dark past

Open quasars are only 5 percent "younger" than the Universe. What was before them, immediately after big bang- it is difficult to fix: hydrogen, formed 300,000 years after the explosion, blocks the radiation of the earliest space objects. Only an increase in the number of stars and the subsequent ionization of hydrogen clouds allows us to break the veil over our "dark past".

To obtain and verify such information, the joint work of several powerful telescopes is required. The key role in this matter belongs to the Hubble Space Telescope and the Sloan Digital Telescope, located at the New Mexico Observatory.

Many stars are much more sun

Rays of light coming from the stars

astronauts in orbit

Before going to bed, I really like to look at the beauty of the starry sky. It seems that there, above - the kingdom of eternal peace and quiet. Just reach out your hand, and the star is in your pocket. Our ancestors believed that the stars could influence our destiny and our future. But not everyone will answer the question of what they are. Let's try to figure it out.

Stars are the main "population" of galaxies. For example, there are more than 200 billion of them shining in our galaxy alone. Each star is a huge hot luminous ball of gas, like our Sun. A star shines because it releases an enormous amount of energy. This energy is generated as a result of nuclear reactions at very high temperatures.

Many of the stars are much larger than the Sun. And our Earth is a speck of dust compared to the Sun! Imagine that the Sun is a soccer ball, and our planet Earth is as small as a pinhead in comparison! Why do we see the Sun so small? It's simple - because it is very far from us. And the stars look very small because they are
much, much further. For example, a ray of light travels the fastest in the world. It can circle the entire Earth before you can blink an eye. So, the Sun is so far away that its beam flies to us for 8 minutes. And the rays from other closest stars fly to us for 4 whole years! Light from the most distant stars flies to the Earth for millions of years! Now it becomes clear how far the stars are from us.

But if the stars are the Suns, then why do they shine so faintly? The farther away the star, the wider its rays diverge, and the light is scattered throughout the sky. And only a tiny portion of these rays reaches us.

Although the stars are scattered throughout the sky, we see them only at night, and during the day they are not visible against the background of bright sunlight scattered in the air. We live on the surface of the planet Earth and seem to be at the bottom of the ocean of air, which constantly worries and seethes, refracting the rays of the light of stars. Because of this, they seem to us to blink and tremble. But astronauts in orbit see the stars as colored non-blinking dots.

The world of these celestial bodies very varied. There are giant stars and supergiants. For example, the diameter of the star Alpha is 200 thousand times larger than the diameter of the Sun. The light of this star travels the distance to the Earth in 1200 years. If it were possible to fly around the giant's equator by plane, then this would take 80 thousand years. There are also dwarf stars, which are significantly inferior in size to the Sun and even the Earth. The matter of such stars is characterized by extraordinary density. Thus, one liter of Kuiper's "white dwarf" matter weighs about 36,000 tons. A match made from such a substance would weigh about 6 tons.

Take a look at the stars. And you will see that they are not all the same color. The color of a star depends on the temperature on their surface - from several thousand to tens of thousands of degrees. Red stars are considered "cold". Their temperature is "only" about 3-4 thousand degrees. The surface temperature of the Sun, which is yellow-green in color, reaches 6,000 degrees. White and bluish stars are the hottest, their temperature exceeds 10-12 thousand degrees.

This is interesting:

sometimes you can watch the stars fall from the sky. They say that when you see a shooting star, you need to make a wish, and it will surely come true. But what we take for shooting stars are just small stones flying from outer space. Approaching our planet, such a stone collides with an air shell and, at the same time, becomes so hot that it begins to glow like an asterisk. Soon the "asterisk", not reaching the Earth, burns out and goes out. These " space aliens are called meteors. If part of the meteor reaches the surface, then it is called a meteorite.

On some days of the year, meteors appear in the sky much more often than usual. This phenomenon is called a meteor shower or they say that it is "raining stars".

In May 2015, the Hubble telescope recorded an outburst of the most distant, and therefore the oldest known galaxy to date. The radiation took as much as 13.1 billion light years to reach the Earth and be recorded by our equipment. According to scientists, the galaxy was born about 690 million years after the Big Bang.

One would think that if the light from the galaxy EGS-zs8-1 (namely, such an elegant name was given to it by scientists) flew to us for 13.1 billion years, then the distance to it would be equal to that which the light will travel in these 13 .1 billion years.


The EGS-zs8-1 galaxy is the most distant among all discovered to date

But we must not forget some features of the structure of our world, which will greatly affect the calculation of the distance. The fact is that the universe is expanding, and it does so with acceleration. It turns out that while light traveled 13.1 billion years to our planet, space expanded more and more, and the galaxy moved away from us faster and faster. A visual process is shown in the figure below.

Given the expansion of space, the most distant galaxy EGS-zs8-1 is currently approximately 30.1 billion light years away from us, which is a record among all other similar objects. Interestingly, until a certain point, we will discover more and more distant galaxies, the light of which has not yet reached our planet. It is safe to say that the record of the EGS-zs8-1 galaxy will be broken in the future.

This is interesting: there is often a misconception about the size of the universe. Its width is compared with its age, which is 13.79 billion years. This does not take into account that the universe is expanding with acceleration. According to rough estimates, the diameter of the visible universe is 93 billion light years. But there is also an invisible part of the universe, which we will never be able to see. Read more about the size of the universe and invisible galaxies in the article "".

Let's leave our sunny city and set off mentally to travel to the far reaches of the universe.
It has already been said in this book that even in ancient times people called the stars fixed. In fact, the entire firmament revolves around the Earth (now you know that this rotation is apparent). And one star from another is always at the same distance.
Here is the constellation Ursa Major. What figure its seven stars formed two thousand years ago, it is the same now, it will remain the same for several thousand years.
However, the immobility of the stars is apparent: they rush with great speed in the world space, but we do not notice their movements, since the stars are terribly far from us.
For centuries, astronomers have been trying to find out how far the stars are from us, and have been unable to do so.
In 1837, the director of the Pulkovo Observatory, V. Ya. Struve, managed to find the distance to the star Begi. It turned out that this star is about 1700 thousand times farther from us than the Sun!
It was important to take the first step. Simultaneously with Struve and later, scientists found the distance to many stars.
Astronomers have named the star closest to us Proxima, in Latin it means “Nearest”. Proxima (it is located in the constellation Centaurus) is a small star, it is visible only in a good telescope and only from the southern hemisphere of the Earth.
Let's calculate how soon we can get to Proxima.
And where are we going?
Imagine a fantastic picture.
A rail track has been laid to Proxima, and the first passenger train is waiting for a signal to depart. You and I, out of breath, run to the checkout.
- Any more tickets to Proxima?
- Please. - calmly answers the cashier.
- Two tickets!
- Pay money.
- How much?
“Now I’ll count,” the cashier says. - Since the path is long, the authorities of the road set a price favorable to the public: one ruble for every million kilometers.
- It's a real gift! We are delighted to be surprised.
- Wait a bit! the cashier smiles. - So, one ruble per million kilometers is one hundred and fifty rubles per astronomical unit. And to Proxima, two hundred and sixty thousand astronomical units, which means ... thirty-nine million rubles from you, citizens!
We back away from the cash register in fright.
- And ... and how long will the train go?
“Now let’s calculate this as well,” the cashier reassures us. - We send express - three hundred kilometers per hour. The path to the Sun would take fifty-eight years, and to Proxima two hundred and sixty thousand times further ... In fifteen million years you will reach the goal, comrades!
- Will there be stations along the way?
- Hardly ... Unless some kind of comet will fall.

We embarrassedly back away from the cash register.
We'll come back next time when we're free...
The cashier looks after us sadly.
- Apparently, the flight will not take place. All passengers flee...
It turns out that a train for interstellar travel is completely inappropriate. We remember the rocket. Let us suppose that a fuel has already been invented that makes the rocket move at 20 kilometers per second, 72,000 kilometers per hour.
Now you and I will find out that it is not at all more profitable to fly on a rocket. The speed of the rocket is 240 times the speed of the train, which means that it will take 240 times less time. Divide 15 million by 240.

Though! Even a rocket will have to fly 62,500 years. How far are the stars from us!
It has already been said in this book that the fastest thing in the world is a light beam. Every second he runs a distance of 300 thousand kilometers - almost as much as from the Earth to the Moon. Now if only to travel on a light beam!
The distance from the Earth to the Sun, that is, one astronomical unit, the light beam will run in 8 minutes 20 seconds. There are 1440 minutes in a day, which is 173 times more than 8 minutes 20 seconds. This means that in a day light travels about 173 astronomical units, and in a year it travels 63,000 astronomical units, that is, a path that is 63,000 times greater than the distance from the Earth to the Sun.
The distance that light travels in a year is called a light year by astronomers, and this huge measure of length measures distances in the universe.
Indeed, the astronomical unit is good for the solar system, but when it comes to stellar distances, it becomes quite small. Even to Proxima, 260 thousand astronomical units, but there are stars that are thousands and even millions of times further from the Earth. Measuring the distance to such stars in astronomical units is like measuring the distance from Moscow to Vladivostok in millimeters.
Remember firmly: a year is a measure of time, 365 and a quarter of a day; a light year is a measure of length, 63,000 astronomical units.
How many light years to Proxima? There are 63,000 astronomical units in one light year, and in total there are 260 thousand astronomical units before Proxima - this means that it is more than four light years away. oskakkah.ru - site
Here is another fantastic scene.
An expedition sent from Earth to Proxima got there. Travelers have taken with them a powerful radio transmitter and are talking to the Earth.
- Hello Hello! Proxima speaking! Earth, can you hear us?
- Hello, hello, says the Earth! We hear Proxima well! How was the journey?
- Very good! There were no major incidents along the way. We are waiting for people and food to be sent.
"Didn't you find habitable planets there?"
- Haven't found it yet. They settled temporarily on one small planet, but nature on it is scarce and food is not suitable for earthly stomachs.
- All right, we'll send passenger and transport ships. This is where we end the conversation. Goodbye, Proxima!
- Goodbye, Earth!
How long do you think this little conversation will take? Over 25 years! More than eight years will pass between each question and getting an answer to it, since radio waves travel through space at the same speed as light.
Light with its colossal speed, 300 thousand kilometers per second, rushes from Proxima to us for more than four years. And there are stars that are immeasurably further away.
The Universe is immense! And it is almost impossible to imagine how far even the nearest stars are from us. Perhaps stories about the train, about the rocket, and about talking on the radio will help you.
How small the universe was imagined by the ancients!
In one ancient Greek legend, it is said that the god Hephaestus dropped an anvil from the sky, and it flew to the Earth for nine days and nine nights. To the ancient Greeks, this distance seemed incredibly large, and a falling object will pass only 580 thousand kilometers in nine days - this is a little further than from the Earth to the Moon.
Even solar system thousands of times larger than the entire universe in the view of the Greeks.
