Interesting facts about space far and near. Cognitive information about space that everyone should know

Space will always be of interest to people. Even those who are far from . Therefore, it is no coincidence that every year we manage to learn some new ones.

In this article, we have prepared for you a lot of fascinating information about space and astronauts, as well as about the structure of the Universe in general. Perhaps some things you already know, but something, after all, you will hear for the first time.

So in front of you the most interesting facts about space.

tenth planet in the solar system

Did you know that in 2003, American astronomers managed to discover the 10th planet, located behind? She was named Eris.

This discovery was made possible thanks to a new and improved technique. Soon, other space objects were also discovered. They, along with Pluto and Eris, were called transplutonic.

It is worth noting that such discoveries are of interest to scientists also because they are trying to find out what advantages and dangers this or that cosmic body can conceal.

Scientists are constantly looking for life on other planets. This is due to the frightening events that are unfolding today on. We are talking about the threat of nuclear war, epidemics, global cataclysms and many other factors.

Mysterious Moon

Telling interesting facts about space, one cannot fail to mention the Moon. Indeed, despite the fact that, compared to other celestial bodies, the Moon is the best studied, we still do not know much about it.

Here are just a few of the mysteries that have yet to be answered:

• Why is the moon so large? It is important to understand here that in the solar system, the planets do not have natural satellites comparable in size to the moon.
• What is the reason that the diameter of the lunar disk at the time of total eclipse ideally covers the disk of the sun?
• What makes the moon rotate in a regular circular orbit? This question is difficult to answer, since the orbits of the remaining satellites are ellipsoid?

Where is the twin of the Earth

According to some scientists, the Earth has a twin. It turned out that on the satellite - Titan, the conditions are very similar to our planet.

There is also a sufficient amount of a similar air shell present and observed.

At the moment, Titan is of particular interest in the scientific community and continues to be actively investigated by specialists.

Mystery of Mars

The Red Planet is a nickname given to it because of its color. Water was discovered on this planet, and a suitable temperature and atmosphere were determined for the existence of living organisms.

In the middle of the 20th century, there was a popular song that apple trees would soon bloom on Mars. However, it still remains uninhabited.

Scientists are trying to find any signs of life, but research is not easy. The main problem is the long distance to this coveted planet.

An interesting fact is that today Mars is the second most studied object in space after the Earth.

Why did the flights to the moon stop?

Since the Moon is closest to the Earth, it never ceases to interest the minds of people. In 1969, the Americans visited it and managed to collect important space data about this satellite. Today, scientists continue research in one form or another.

However, after American astronauts flew to the moon, the satellite study program was abruptly terminated.

Naturally, this leads to many questions and bewilderment: why was a successful space exploration project closed without sufficient reason?

There is an opinion that there was no flight at all, and all photos and videos allegedly taken in space were simply falsified in an American film studio.

Considering the fact that the Cold War was in full swing at the time, such a forgery is quite possible to assume.

The first astronaut to visit the moon, Neil Armstrong, claimed that there is another form of life there, in the fight against which a person cannot emerge victorious. However, his opinion does little to clarify the situation as a whole.

Unfortunately, today many facts about this space object remain classified. Perhaps in the near future we will learn some new interesting facts about the Moon and what space explorers hid from us.

space toilet

An interesting fact is that before sending the first man into space, scientists faced an unusual problem: what should be the toilet so that astronauts can use it normally in a state of weightlessness?

It is only at first glance that it may seem that creating a toilet for astronauts is a simple task. In fact, everything is much more complicated.

The sewerage system must function without failure. For example, during the takeoff of a spacecraft and its subsequent spacewalk, astronauts have to use special diapers.

As soon as they began to build a rocket, designers paid special attention to the invention of plumbing devices. They were developed taking into account the individual anatomical features of the crew members.

Every year, toilets in spacecraft have become more versatile, thoughtful and comfortable.

Superstitions on board

Astronauts, like other people, have many superstitions.

For example, when they go into space, they take a branch of wormwood with them so that its smell reminds them of the Earth. Before the launch, Russian cosmonauts must turn on the song of the Zemlyane group - "Earth in the window".

The founder of practical Soviet cosmonautics, he never allowed space flights to take place on Mondays. He himself did not comment on this in any way, although because of this decision he had many conflicts with the leadership.

Once, when the launch was nevertheless carried out on Monday, by a fatal accident, a whole series of accidents occurred.

On October 24, 1960, a ballistic missile suddenly exploded at Baikonur. From that moment on, this sad date became associated with bad luck. And today, on this day, no work is usually carried out at spaceports.

Unknown facts about space and Russian cosmonautics

The peak of the popularity of Russian cosmonautics fell on the Soviet era. Scientists and designers managed to achieve phenomenal results that amazed the whole world.

However, against the backdrop of victories, there were also tragic moments that need to be treated with understanding. The exploration of outer space was made by a new and unexplored direction in science, so mistakes were inevitable.

Here are some interesting facts you may not have heard of.

• On the monument installed in Star City, you can see a camomile, which the astronaut holds in his hand.
• Many people think that the first living beings sent into space were, but this is not so. In fact, they were turtles.
• Do you know why in the middle of the 20th century, 2 spaceports were built in the Soviet Union? This was done in order to mislead the enemy. Wooden structures imitating real space structures were erected from Baikonur at a distance of 300 km.

Funny discoveries and interesting facts about space

• Saturn has a very low density and is a very light planet. If he could be immersed in water, he would not drown in it.
• Among all the planets of the solar system, is the largest. Surprisingly, all the planets revolving around the Sun could fit inside it.
• The very first star catalog was compiled by the ancient scientist Hipparchus, who lived in the 2nd century BC. e.
• In 1980, the "Lunar Embassy" was formed, dealing with the sale of territories on the Moon. By the way, about 8% of the lunar surface has already been sold by the position today. So if you are interested in space from a practical point of view - hurry up!
• An interesting fact is that the Americans spent huge amounts of money on the development of a special pen that could write in space. Indeed, in a state of weightlessness, ink does not flow from the rod, as it happens on earth. Soviet cosmonauts considered this problem somewhat far-fetched, and took into space for notes ... a pencil.

NASA's most unusual claims

Throughout its history, NASA has made many different statements, some of which were very unusual and even strange.

• Being in zero gravity, astronauts suffer from "space sickness", accompanied by nausea and pain. This is due to a violation of the full functioning of the inner ear.
• The fluid in the astronaut's body tends to get into the head, as a result of which his nose is blocked, and his face noticeably swells.
• In outer space, a person becomes taller due to the lack of pressure on his spine.
• A snoring person on Earth, in zero gravity, will not make any sounds.

Space is the most discussed and, at the same time, the most mysterious topic on the entire planet Earth. On the one hand, humanity has learned a lot about it, on the other hand, we know a tiny percentage of what is actually happening in the Universe.
Today we will look at some of the most interesting facts about space.
1. It turns out that our satellite - the Moon - is moving away from us every year by about 4 cm. This depends on the decrease in the period of rotation of the planet by 2 miles of a second per day.
2. Forty new stars are born every year in our Galaxy alone. It is difficult to even imagine how many of them appear in the entire universe.
3. The universe has no boundaries. It seems that everyone is familiar with this statement. In fact, no one knows if the cosmos is infinite or just gigantic.

a) In the vastness of the Universe there is a very amazing thing - a giant gas bubble. Its length is about 200 million light years, and it is located 12 billion of these years from us! This interesting thing formed just two billion years after the Big Bang.

b) The Sun is about 110 times larger than the Earth. It is even larger than the giant of our system - Jupiter. However, if we compare it with other stars in the Universe, our luminary will take a place in the nursery of a kindergarten, that's how small it is.
Now let's imagine a star that is 1500 times larger than our Sun. Even if we take the entire solar system, it will not take up more than a pixel of this star. This giant has VY Canis Major, whose diameter is about 3 billion km. How and why this star was blown to such dimensions, no one knows.

c) Science fiction writers have imagined about five different types of planets. It turns out that there are hundreds of times more of these species. Scientists have already discovered about 700 types of planets. One of them is a diamond planet, and in every sense of the word. As you know, carbon needs very little to turn into a diamond in this case, the conditions coincided so that one of the planets solidified and turned into a gem of a universal scale.

5. A black hole is the brightest object in the entire universe.
Inside a black hole, the force of gravity is so strong that even light cannot escape from it. Logically, the hole should not be visible in the sky at all. However, during the rotation of the hole, in addition to cosmic bodies, they also absorb gas clouds, which begin to glow, twisting in a spiral. Also, meteors, falling into black holes, light up from an incredibly sharp and fast movement.

6. The light of our Sun, which we see every day, is about 30 thousand years old. The energy we receive from this celestial body was formed in the core of the Sun about 30 thousand years ago. That's how much time and no less is necessary for photons to break through from the center to the surface. But after the "liberation" they need only 8 minutes to get to the surface of the Earth.

7. We fly through space at a speed of about 530 km per second. Inside the Galaxy, the planet moves at a speed of about 230 km per second, the Milky Way itself flies through space at a speed of 300 km per second.
8. About 10 tons of cosmic dust “falls” on our heads every day.

9. There are over 100 billion galaxies in the entire universe. There is a chance we are not alone.
10. An interesting fact: about 200 thousand meteorites fall on our planet every day!
11. The average density of Saturn's substances is two times less than the density of water. This means that if you lower this planet into a glass of water, it will float on the surface. You can check this, only, of course, if you find the appropriate glass.
12. The sun is losing weight by a billion kilograms per second. This is due to the solar wind - a stream of particles that move from the surface of this star in different directions.
13. If you wanted to get by car to the nearest star after the Sun - Proxima Centauri, then we, at a speed of 96 km / h, would need about 50 million years.

14. Even on the Moon, earthquakes occur, which are referred to as moonquakes. But, nevertheless, in comparison with the earthly ones, they are insignificantly weak. There are more than 3,000 such moonquakes every year, but this total energy would only be enough for a small salute.

15. The neutron star is considered the strongest magnet in the entire universe. Its magnetic field is millions of billions of times greater than the field of our planet.

16. It turns out that in our solar system there is a body resembling our planet. It is called Titan, and it is a satellite of the planet Saturn. It also has rivers, seas, volcanoes, a dense atmosphere, just like our planet. Surprisingly, even the distance between Titan and Saturn is equal to the distance between us and the Sun, and even the ratio of the weight of these heavenly bodies is equal to the ratio of the weight of the Earth and the Sun.
Yet intelligent life on Titan is not even worth looking for, because its reservoirs failed: they consist mainly of propane and methane. But still, if the latest discovery is confirmed, then it will be possible to argue that primitive life forms exist on Titan. Under the surface of Titan there is an ocean, which consists of 90% water, the remaining 10% can be complex hydrocarbons. There is an assumption that it is these 10% that can give rise to the simplest bacteria.

17. If the Earth revolved around the Sun in the opposite direction, then the year would be two days shorter.
18. The duration of a total lunar eclipse is 104 minutes, while the duration of a total solar eclipse is only no more than 7.5 minutes.

19. Isaac Newton first set out the physical laws that artificial satellites obey. They were first published in the work "Mathematical Principles of Natural Philosophy" in the summer of 1687.

20. The funniest fact! Americans have spent more than one million dollars to invent a pen that would write in space. The Russians, on the other hand, used a pencil in zero gravity without making any changes to it.

The cosmos is the greatest mystery that humanity will always want to unravel. He pulls with his extraordinary properties and mysteries. Today we have revealed nothing at all, but I hope that the Universe has become more accessible and interesting for you.

Almost all children are fond of space. Someone only for a short time, until he learns about how the world works. And someone - seriously and for a long time, dreaming of one day flying to the moon or even further, repeating Gagarin's feat or discovering a new star.

In any case, the child will be interested to learn about what is hidden behind the clouds. About the Moon, about the Sun and stars, about spaceships and rockets, about Gagarin and the Queen. Fortunately, there are many books that will help kids, schoolchildren, and even adults to discover the Universe for themselves. And here are a few excerpts from them:

1. Moon

The moon is a satellite of the earth. So astronomers call it because it is constantly near the Earth. It revolves around our planet and cannot get away from it anywhere, because the Earth attracts the Moon to itself. Both the Moon and the Earth are celestial bodies, but the Moon is much smaller than the Earth. The Earth is a planet and the Moon is its satellite.

2. Month

The moon itself does not shine. The glow of the Moon, which we observe at night, is the light of the Sun reflected by the Moon. On different nights, the Sun illuminates the Earth's satellite in different ways.

The Earth, and with it the Moon, revolve around the Sun. If you take a ball and shine it with a flashlight in the dark, then on the one hand it will appear round, because the light of the flashlight falls directly on it. On the other side, the ball will be dark because it is between us and the light source. And if someone looks at the ball from the side, he will see only part of its surface illuminated.

A flashlight is like the Sun, and a ball is like the Moon. And we from the Earth look at the Moon on different nights from different points of view. If the light of the sun falls directly on the moon, it appears to us in a full circle. And when the light of the Sun falls on the Moon from the side, we observe a month in the sky.

3. New Moon and Full Moon

It happens that the moon is not visible at all in the sky. Then we say that the new moon has come. It happens every 29 days. On the night following the new moon, a narrow lunar crescent appears in the sky, or, as it is also called, a month. Then the crescent begins to grow and gradually turns into a full circle, the moon - the full moon comes.

Then the moon decreases again, “falls down”, until it again turns into a month, and then the month disappears from the sky - the next new moon will come.

4. Lunar Jump

Do you want to know how far you could jump if you were on the moon? Go outside with chalk and a tape measure. Jump as far as you can, mark your result with chalk and measure the length of your jump with a tape measure. Now measure six more of the same segments from your mark. That's what your moon jumps would be like! This is because the moon has less gravity. You will be in the jump longer and you will be able to set a space record. Although, of course, the suit will prevent you from jumping.

5. Universe

The only thing we know for sure about our Universe is that it is very, very big. The universe began around 13.7 billion years ago with the Big Bang. Its cause remains one of the most important mysteries of science to this day!

Time passed. The universe expanded in all directions and finally began to take shape. From the whirlpools of energy, tiny particles were born. Hundreds of thousands of years later, they merged and turned into atoms - “bricks” that make up everything that we see. At the same time, light arose, which began to move freely in space. But it took hundreds of millions more years before the atoms united into huge clouds, from which the first generation of stars was born. When these stars separated into groups to form galaxies, the universe began to resemble what we see now when we look at the night sky. Now the Universe continues to grow and every day it only gets bigger!

6. The birth of a star

Do you think stars can only be seen at night? But no! Our Sun is also a star, but we see it during the day. The sun is not much different from other stars, it's just that the rest of the stars are much further from the Earth and therefore seem so small to us.

Stars are formed from clouds of hydrogen gas left over from the Big Bang or from the explosions of other, older stars. Gradually, the force of gravity connects the hydrogen gas into clumps, where it begins to rotate and heat up. This continues until the gas becomes dense and hot enough for the nuclei of hydrogen atoms to fuse. As a result of this thermonuclear reaction, a flash of light occurs, and a star is born.

7. Yuri Gagarin

Gagarin was a fighter pilot in the Arctic, then he was selected from hundreds of other military pilots in the cosmonaut corps. Yuri studied well and was ideally suited for height, weight and physical fitness. April 12, 1961, after the famous 108 minutes of flight in space, Gagarin became one of the most famous people in the world.

8. Solar system

The solar system is a very busy place. Eight planets revolve around the Sun in elliptical (slightly elongated circular) orbits, including our Earth. Seven more are Jupiter, Saturn, Uranus, Neptune, Venus, Mars and Mercury. The rotation of each of the planets lasts differently, from 88 days to 165 years.

Since ancient times, space has attracted people, interesting facts about the universe can bring closer and interest in space even more!

1. The brightest object in the universe is a black hole.. The inner part of it has such a strong gravity that the light cannot escape. It would be logical if a black hole could not be seen in the sky. But as the hole rotates, it absorbs not only cosmic bodies, but also clouds of gas, twisting into a spiral shape. They make the Black Hole luminous and bright. In addition, meteors sucked into the Black Hole ignite inside it due to the high speed of movement.
2. There is a giant bubble in the universe, which contains only gas. It appeared, by the standards of the Universe, recently, only two billion years after the Big Bang. The length of the bubble is 200 million space years, and the distance from the Earth to the gas bubble is 12 billion space years.

   

3. The light we see is thirty thousand years old. So many years it takes photons to get out of the solar center to its surface. They get to the earth's surface very quickly - they spend only 8 minutes on it.

   

4. Saturn will not sink if immersed in a huge bathtub filled with water, but will remain on the surface. This happens because the density of all substances on this planet is two times lower than the density of water.

   

5. There is a body in the solar system that looks like Earth. It is called Titan and is a moon of Saturn. On the surface of the body there are rivers, volcanoes, seas, and the atmosphere has a high density. The distance between Saturn and its satellite is approximately equal to the distance from us to the Sun, the ratio of the masses of bodies is approximately the same. But intelligent life on Titan, most likely, will not be due to reservoirs - they consist of methane and propane.

   

6. The most distant stars we see look like they did 14,000,000,000 years ago. The light from these stars reaches us through space through many billions of years, while it has a speed of 300 thousand kilometers per second.

   

7. The sun is losing its weight very quickly. It has solar winds, during which particles then fly away from the surface. In a second, the Sun loses up to a billion kilograms, since even the smallest particle of dust (the size of a poppy seed) can kill a person.

   

8. Ursa Major is the most popular constellation. But, in fact, this is not a constellation at all, but an asterism. This term refers to the clusters of stars that a person sees in the sky, but in fact the distance between them is many light years, and they are in different galaxies. The angle of the Earth in relation to these stars allows you to see the shape of the bucket.

   

9. If you put two pieces of metal together in space, they will fuse together.. On Earth, this does not happen due to instantaneous oxidation.

   

10. Since 1980, the surface of the moon has been sold. To date, 7 percent of the area of ​​the Moon has been sold. 10 acres on the Earth's satellite cost $30. Together with the paper on the ownership of the site, the buyer is also given a photo of the site taken from the satellite.

    

11. The Earth, in addition to the Moon, has three more satellites.. At the end of the 19th century, scientists discovered an asteroid five meters in diameter, which revolved around the Sun at the frequency of the Earth, and therefore revolved near the Blue Planet. For this reason, the asteroid was called the second satellite. After some time, three more similar satellites were discovered.

    

12. No sound is heard in space. Voyager tried to fix the noise in space using a plasma wave, but could not hear the sound, since the gas in interstellar space is not so dense. If a wave of sound passed through a cosmic gas cloud, the human ear would not hear anything, since the eardrums are not very sensitive.

    

13. Humans are made of stardust. When the Big Bang happened, the resulting particles combined with helium and hydrogen, then due to the heat combined into elements, including iron.

    

14. No one knows how many stars in the universe. They are considered in approximate numbers and only in the Milky Way. To count all the stars, the number of stars in the Milky Way must be multiplied by the number of galaxies. According to recent studies, there are about 60 sextillion stars.

    

15. In space, reduced pressure, which in zero gravity affects the spine. Astronauts during their journey can increase in height by about 3-5 centimeters.

    

How much does a space suit cost and how does it work? How to calculate the force of gravity between celestial bodies and at what speed does the Milky Way galaxy rotate? How old is the Universe and what happens if you fall into a black hole? You can find answers to these and a number of other questions in this collection of facts about space.

Cygnus, in the constellation Cygnus, is a very large star in the known universe - a hypergiant. It is almost a million times larger than the Sun.

The planet Uranus was discovered by William Herschel, who wanted to name the planet George, after King George III, but ultimately chose Uranus.

The first rockets were made 1000 years ago in China.

Robert Goddard launched the first liquid propellant rocket engine in 1926.

Over 100 artificial satellites are currently launched into space each year. Some of them are space telescopes.

The lower the satellite's orbit, the faster it must fly to avoid falling to Earth. Most satellites fly in low orbits - 300 km from the Earth.

Hipparchus was the first astronomer who tried to find out the distance to the Sun.

The red color of Mars is due to oxidized (rusty) iron on its surface.

Jupiter doesn't have a surface for spacecraft to land on because it's made up mostly of helium and hydrogen. Jupiter's gravity compresses the hydrogen so much that it turns into a liquid.

The first successful planetary space probe was Mariner 2, which flew past Venus in 1962.

Voyager 2 flew 600,000,000 km and is moving out of the solar system after passing close to Neptune in 1989.

To save fuel on flights to distant planets, space probes can use the gravity of neighboring planets to eject. It's called a slingshot.

Hubble's law showed that the universe is becoming everything. This led to the idea of ​​the Big Bang.

First, astronomers thought that regular pulses from deep space could be signals from aliens, and pulsars were jokingly called LGMs (short for Little Green Men - MZCH - little green men).

Pulsars probably originated from a supernova explosion - which is why most of them are in the plane of the disk of the Milky Way.
