Man managed to overcome the force of gravity and escape into outer space; modern telescopes allow scientists to look even into neighboring Universes, but at the same time, space still holds many mysteries. And, it would seem, not all earthlings know sufficiently studied issues. Our review contains some very interesting facts about extraterrestrial space.
1. The taste of food in space changes
Astronauts who enter orbit completely change their food preferences. For example, International Space Station astronaut Peggy Whitson said that her favorite food on Earth, shrimp, is simply disgusting to her in space.
2. Betelgeuse
Betelgeuse is a red star that is so huge that its diameter is larger than the diameter of the Earth's entire orbit around the Sun.
3. The danger of space debris
The risk of being seriously injured by a piece of space debris falling from orbit is 1 in 100 billion.
4. Celestial bodies in the solar system
Jupiter's mass is 2.5 times greater than all other planets in the solar system combined. Moreover, the mass of the Sun accounts for 99.86% of the mass of all matter in the Solar System.
5. Water can miraculously float in space
Far out in the galaxy (10 billion light-years away from Earth) there is a huge cloud of water vapor containing 40 trillion times more water than Earth's oceans.
6. Moon and Earth
The volume of the Moon is approximately equal to the volume of the Pacific Ocean.
7. Galaxy Sombrero
There is a galaxy 28 million light years from Earth that looks exactly like a Mexican sombrero. It can be seen with a regular telescope.
8. Names of Mars
The soil of Mars is rich in iron, which gives the planet's surface a reddish color. Because of this, the Egyptians called it Desher ("red"), and the Chinese called Mars the "fiery star." The Romans named the planet Mars, in honor of the god of war (the equivalent of Ares in Greek mythology).
9. Calculation on Venus
Venus orbits the Sun faster than Earth, but it also rotates surprisingly slowly on its axis. Venus revolves around the Sun in 225 days, and it rotates around its axis in 243 Earth days. Thus, a year on Venus is shorter than a day.
10. Apollo 11
The Apollo 11 spacecraft, which carried Neil Armstrong, Buzz Aldrin and Michael Collins to the Moon, landed on the surface of the Moon, as they say, “end-to-end”. There was only 20 seconds of fuel left in the braking engine.
11. Little stars
The densest and tiniest stars that have been found so far are neutron stars. They can have a mass many times greater than the Sun, but their size is only 20 km.
12. Collision of Galaxies
The Andromeda Galaxy flies through space towards the Milky Way at a speed of 110 km/s. The collision is expected in four billion years.
13. The most expensive kimchi
There is no way to know how many stars there are.
Astronomers were able to estimate (with a huge error) the number of stars in our galaxy, the Milky Way - from 200 to 400 billion stars. New galaxies are constantly being discovered, and given how many billions of galaxies have yet to be discovered, the number of stars in the Universe is simply impossible to estimate.
No less interesting are . For unprepared people, they can seem like real magic.
We still know very little about the vast universe in which we live. Check out our list of 25 thought-provoking space mysteries.
Space contains all sorts of dangers, from deadly radiation to exploding superstars.
However, humanity is determined to go out and explore space, so to make sure we know exactly what we're up to, here are 25 space facts that will definitely surprise you.
Speed of light
Everyone likes to imagine themselves flying through the galaxy at the speed of light, approximately 299,792,458 meters per second; however, the reality can be less fun and much more fatal. Upon contact with an object moving at the speed of light, hydrogen atoms turn into highly radioactive particles that can easily destroy a starship's crew and destroy electronics in a matter of seconds. Even a few stray bubbles of hydrogen gas floating in space could have a radioactive output equivalent to the beam of protons produced by the Large Hadron Collider.
Moon 
Every year our moon is approximately 400,000 km away from Earth, and while this may not seem like a big deal at first, it could have devastating consequences for our planet in the future. Although the Earth's gravitational field should be sufficient to allow the moon to spin freely in space, the increasing distance between it and the Earth will eventually slow down our planet's rotation to the point where one day will take more than a month, and our oceans will not there will be tides..
Black holes 
Black holes, typically formed due to the death of massive stars, are super-dense regions of space with such a strong gravitational pull that they trap light and time. Just a small black hole in our solar system would throw planets out of orbit and tear our sun apart. This in itself is not scary, but black holes can rush across the galaxy at speeds of several million miles per second, leaving a trail of destruction in their path.
Gamma radiation 
The most powerful type of explosion in the Universe, gamma ray bursts are intense, high-frequency bursts of electromagnetic radiation that carry as much energy in milliseconds as our sun will emit over its lifetime. If one of these rays hit Earth, it could strip the atmosphere of ozone in a matter of seconds, and some scientists believe gamma rays are responsible for the mass extinction event 440 million years ago on Earth.
Zero gravity 
Scientifically speaking, microgravity occurs when an object is in free fall and appears weightless. While it may seem fun to float around like astronauts, prolonged periods of time in the absence of gravity lead to long-term mental and physical impairment in humans.
Cold welding 
Here on Earth, gases in the atmosphere react with metals to create a thin layer of oxidation. However, the vacuum of space has no atmosphere and therefore does not cause oxidation on metals, which leads to an interesting reaction. This reaction is called cold welding, and it occurs when two metals of the same molecular composition are pressed together and gradually fuse together as if they were one. While this may sound strange, this caused a lot of problems on the first satellites and made repairs in space difficult.
Extraterrestrial life 
The universe is massive and incredibly old, so the chances of other planets evolving like Earth is unlikely. According to the Fermi paradox, the high probability of extraterrestrial life in space is contradicted by the lack of obvious evidence to support it. At this point, we're not sure which is scarier; the fact that we cannot be alone in the universe or the possibility that we are.
Rogue Planets 
Launched into space after the formation of their planetary system, these planets are bodies that can move freely through space, crashing into anything they encounter along the way. Because they do not orbit the Sun, these planets have low surface temperatures. However, due to their molten cores and icy insulation, some scientists theorize that these free planets may contain massive underground oceans that support life.
Trips 
In 1969, the third lunar module, Apollo 11, took 3 days to land on Earth's natural satellite, the Moon. Since then, our technology has grown rapidly; We could expect to get to Mars in 7-9 months, and getting to Pluto would take about 10 years. Distances beyond our solar system become even more extreme; even traveling at the speed of light, it would take us more than 4 years to reach the nearest star, Alpha Centurion, and more than 100,000 years to reach the galactic center of the Milky Way.
Extreme temperatures 
Depending on where you are in space, you'll likely find yourself in extreme conditions. The heat emitted by a supernova can reach temperatures of 50 million degrees Celsius or more, five times hotter than a nuclear explosion. At the opposite end of the spectrum, the cosmic background temperature of space is measured at minus 270 degrees Celsius, just warmer than absolute zero. You definitely don't want to forget your jacket.
Darkness 
Fear of the dark is not just a fear that children experience; it is an evolutionary trait created by humans to protect against dangers lurking in the unknown. The only reason adults today aren't afraid of what they can't see is because they've learned from experience that the likelihood of monsters hiding under the bed is very low. However, in space, darkness is a completely unexplored void that goes on indefinitely, so fearing the dangers that lurk beyond our vision is an understandable reaction.
Magnetars 
Magnetars are incredibly dense neutron stars. In fact, they're basically an entire star crushed into a sphere that's only 15 miles in diameter. One teaspoon of magnetar contains the same mass as 900 Great Pyramids of Giza. They are also host to the strongest magnetic fields in our universe, fields so strong that anything that gets too close is torn apart at the atomic level.
Musculoskeletal atrophy 
Astronauts visiting the International Space Station show signs of significant muscle wasting after just six weeks in space.
Venus 
Despite taking its name from the Roman goddess of love, Venus is perhaps the most hellish planet in our solar system. With surface temperatures of around 500 degrees Celsius, the atmospheric pressure is 90 times that of Earth, and the constant sulfuric acid rain just landing on Venus will kill you in minutes. This is definitely not a planet you'd want to have a picnic on.
Dark Matter/Dark Energy 
We know very little about our universe. In fact, we've only seen less than 5% of the material it's made from. The other 95% is dark matter and dark energy. About a quarter of the Universe is made up of dark matter, mass that we cannot see or detect. The rest of the Universe is dark energy, the true nature of which is largely unknown. However, we are confident that it plays a crucial role in the expansion of the Universe.
Source radiation 
The Earth's atmosphere and magnetic field protect us from some really nasty things, namely radiation. Cosmic rays, solar winds and electromagnetic particles permeate the universe, so much so that astronauts traveling between Earth and Mars will be exposed to radiation throughout their entire body for 5-6 days. Those who do not succumb to radiation sickness before achieving their goal will almost certainly develop cancer for the rest of their lives.
Expanding Sun 
Our Sun constantly uses nuclear fusion to combine hydrogen and helium together to burn; however, its hydrogen is not infinite, and as it is depleted, the Sun will become hotter and hotter. Eventually it will get so hot that the Earth's atmosphere will burn up and our oceans will boil and evaporate completely. Then, once all of the Sun's hydrogen is gone, it will expand into a red giant and consume Earth once and for all.
Hypernovas 
With 100 times more energy than a standard supernova, hypernovae are powerful explosions that occur after the death of a massive star. Although the factors that cause a hypernova star to form are widely disputed, we know that the result is often a black hole or neutron star. Hypernovae are also the source of gamma-ray bursts in the Universe, and they are bright enough to be seen by telescopes millions of light years away.
Electromagnetic vibrations 
Space is a near-perfect vacuum, which means you can count on your ears not picking up sound while you're in outer space. While the thought of complete silence may be crazy in itself, don't believe that just because you can't hear anything there's no sound. Due to the lack of gases to move them, sound waves are absent in space, but sounds are still transmitted through space using electromagnetic vibrations. NASA recorded some of these vibrations from celestial bodies in our solar system and played them back, resulting in some truly terrifying sci-fi sounds.
Anything can kill you 
There is no room for error in space; even the smallest mistake can kill you. Of the 430 people sent into space, 18 never return home. Today's improvements in spaceflight make it much safer than before. In the 1970s, almost 30% of people who went into space died; however, the furthest we travel is to the moon. A trip to Mars would increase the risk tenfold.
Time distribution 
Imagine an astronaut traveling through space at close to the speed of light. Now imagine a person standing on the Earth. According to Einstein's theory of relativity, an astronaut will experience time much more slowly than a stationary person. When the astronaut finally returns home, even if he has been on earth for many years since he left, it will only be a fraction of that time. This is called time dilation, and while we have yet to develop the technology to move people fast enough to notice its effects, we have seen examples of it when studying high-speed particles in the laboratory.
Stars with hyperspeed 
Believed to be the result of a close encounter with a black hole, hypervelocity stars are stars that have been ejected from their systems and sent into intergalactic space at speeds of up to 2 million miles per hour. While most of the hypervelocity stars we've identified so far are the same size and mass as the Sun, they could theoretically be any size and reach even more incredible speeds.
Solar flares 
Despite the occasional sunburn, our Sun has provided us with warmth and light for billions of years. Don't let our local star fool you, though. Our Sun is a huge incandescent plasma that can make massive bursts of solar radiation at random. While they are unlikely to directly threaten life on Earth, these solar flares can create electromagnetic pulses that destroy power grids, interfere with radio communications, and invalidate technology.
Depressurization 
Apparently there is no air in space; however, this means more danger than simply holding your breath for a long time. The human body is adapted to the atmospheric pressure on Earth, so when you go up in an airplane or travel on mountain roads, ear problems arise. There is no air pressure in a vacuum space. Within seconds, as you exit the confines of your spacecraft, all the water in your body will boil and evaporate, rapidly expanding until you burst like an overfilled balloon.
Big Bang: contraction or expansion? 
Everything must come to an end, but will there be an end to everything? Scientists agree that this will most likely be the final end of the universe, but how this will happen is still uncertain. One prevailing theory is that there will come a point at which the gravitational forces in the universe will reach their limit and cause the entire universe to stop expanding and begin to contract, gradually converging into an infinitesimal point, and then disappear altogether. Another theory, known as the big bang theory, states that the universe will expand to such an extent that gravity becomes meaningless and the cosmos literally falls apart; even particles in atoms eventually float away from each other. We honestly can't decide which is more scary.
Almost all children are interested in space. Someone only learns for a short time about how the world works. And some - 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 in learning about what is hiding 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 children, schoolchildren, and even adults discover the Universe. Here are a few excerpts from them:
1. Moon
The Moon is a satellite of the Earth. Astronomers call it that 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.
Illustration from the book “Fascinating Astronomy”
2. Month
The moon itself does not shine. The glow of the Moon that we see 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 a flashlight on it in the dark, then on one side it will appear round because the light of the flashlight falls directly on it. On the other hand, 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.
The flashlight is like the Sun, and the ball is the Moon. And we from 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 as a complete circle. And when the light of the Sun falls on the Moon from the side, we see a month in the sky.
Illustration from the book “Fascinating Astronomy”
3. New moon and full moon
It happens that the moon is not visible in the sky at all. Then we say that the new moon has arrived. It happens every 29 days. On the night following the new moon, a narrow lunar crescent, or, as it is also called, a month, appears in the sky. Then the crescent begins to grow and gradually turns into a full circle, the moon - the full moon comes.
Then the moon shrinks again, “falls”, until it again turns into a month, and then the month disappears from the sky - the next new moon will come.

4. Moon Jump
Want to know how far you could jump if you were on the moon? Go out into the yard 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 similar segments from your mark. That's what your moonsaults would be like! And all because there is less gravity on the Moon. You will stay in the jump longer and will be able to set a space record. Although, of course, the spacesuit will interfere with your jumping.

5. Universe
The only thing we know for sure about our Universe is that it is very, very large. The universe began about 13.7 billion years ago with the Big Bang. Its reason 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. Tiny particles were born from the vortexes of energy. After hundreds of thousands of years, they merged and turned into atoms - the “bricks” that make up everything that we see. At the same time, light appeared and began to move freely in space. But it took hundreds of millions more years before the atoms coalesced into huge clouds from which the first generation of stars was born. As 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 gets bigger every day!
6. A star is born
Do you think that stars are only visible 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 other 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 combines 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 the 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 to join the cosmonaut corps. Yuri was an excellent student and was ideal in height, weight and physical fitness. On April 12, 1961, after the famous 108 minutes of flight in space, Gagarin became one of the most famous people in the world.
Illustration from the book “Cosmos”
8. Solar system
The solar system is a very busy place. Eight planets, including our Earth, revolve around the Sun in elliptical (slightly elongated circular) orbits. Another seven are Jupiter, Saturn, Uranus, Neptune, Venus, Mars and Mercury. The revolution of each planet lasts differently, from 88 days to 165 years.
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. You may already know some things, but you will hear some things for the first time.
So, in front of you the most interesting facts about space.
Tenth planet of the solar system
Did you know that in 2003, American astronomers managed to discover the 10th planet located beyond? It was named Eris.
This discovery was made thanks to new and improved technology. Soon other space objects were also discovered. They, along with Pluto and Eris, were usually called transplutonian (see).
It is worth noting that such discoveries are also of interest to scientists because they are trying to find out what advantages and dangers this or that cosmic body may conceal.
Scientists are constantly searching 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 disasters and many other factors.
Mysterious Moon
When telling interesting facts about space, one cannot fail to mention. After all, despite the fact that, compared to other celestial bodies, the Moon has been studied best, we still don’t know much about it.
Here are just some of the mysteries whose answers have not yet been found:
- Why is the Moon so large? It is important to understand here that in the Solar System the planets do not have natural satellites (see), comparable in size to the Moon.
- What is the reason for the fact that the diameter of the lunar disk at the moment of a total eclipse perfectly 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 elliptical?
Where is the Earth's twin located?
According to some scientists, the Earth has a twin. It turned out that on the satellite, conditions are very similar to our planet.
A similar air shell is also present and observed there in sufficient quantities.
At the moment, Titan is of particular interest in scientific circles and continues to be actively studied by specialists.
The Mystery of Mars
The Red Planet is a nickname it received because of its color. Water was discovered on this planet, and a suitable temperature and atmosphere for the existence of living organisms was determined.
In the mid-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 conducting research is quite difficult. 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 Earth.
Why did flights to the moon stop?
Since the Moon is closest to the Earth, it never ceases to interest people's minds. In 1969, they 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 program to study the satellite was suddenly stopped.
Naturally, this leads to many questions and causes bewilderment: why was a successful space exploration project closed without sufficient grounds?
There is an opinion that there was no flight at all, and all the photos and videos allegedly taken in space were simply falsified in an American film studio.
Considering the fact that at that time the Cold War was in full swing, such a forgery is quite possible.
The first astronaut to visit the Moon, Neil Armstrong, argued that there was another form of life there, in the fight against which man could not 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 researchers were hiding from us.
Space toilet
An interesting fact is that before sending the first man into space, scientists faced an unusual problem: what kind of toilet should the astronauts be able to use normally in a state of weightlessness?
It is only at first glance that it may seem that creating a toilet for astronauts is an easy task. In reality, everything is much more complicated.
The sewage system must function without interruption. 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 the rocket, the designers paid special attention to the invention of plumbing devices. They were developed taking into account the individual anatomical characteristics of the crew members.
Every year, toilets in spacecraft became more and more versatile, thoughtful and comfortable.
Superstitions on board
Astronauts, like other people, have many superstitions.
For example, when going into space, they take a branch of wormwood with them so that its smell reminds them of Earth. Before the launch, Russian cosmonauts always play the song of the group “Earthlings” - “Earth in the Porthole”.
The founder of practical Soviet cosmonautics, never allowed space flights to take place on Mondays. He himself did not comment on this, although because of this decision he had many conflicts with management.
Once, when the launch was finally carried out on Monday, by fateful 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 types of work are usually carried out at the cosmodromes.
Unknown facts about space and Russian cosmonautics
The peak of popularity of Russian cosmonautics occurred during 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. Space exploration was a new and unknown direction in science, so mistakes were inevitable.
Here are some interesting facts that you may not have heard of.
- On the monument erected in Star City, you can see a daisy that the astronaut is holding in his hand (see).
- Many people think that the first living beings sent into space were, but this is not so. In fact they were.
- Do you know why in the middle of the 20th century, 2 cosmodromes were built in the Soviet Union? This was done with the aim of misleading the enemy. Wooden structures imitating genuine space structures were erected from Baikonur at a distance of 300 km.
Fun 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 in the solar system, it is the largest. Surprisingly, all the planets orbiting 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, engaged in the sale of territories on the Moon. By the way, as of today, about 8% of the lunar surface has already been sold out. 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 developing a special pen that could write in space. After all, in a state of weightlessness, ink does not flow out of the rod, as it does on earth. Soviet cosmonauts considered this problem somewhat far-fetched, and took… a pencil into space to take notes.
NASA's Most Unusual Statements
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 occurs due to disruption 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 becomes blocked and his face visibly swells.
- In outer space, a person becomes taller due to the lack of pressure on his spine.
- A snoring person on Earth, in conditions of weightlessness, will not make any sounds.

Space is perhaps one of the biggest mysteries for all of humanity at the moment. People never tire of exploring space, discussing it, putting forward a wide variety of theories, making a wide variety of assumptions, but still space remains something incredible, mysterious, and completely unidentified. And does it have an end that can be reached, guided by science? Most likely not. Probably, throughout the entire existence of mankind, space will, to one degree or another, remain a mystery, an insoluble riddle, like a huge Sphinx whose question cannot be answered. But still it is studied, and therefore we know a lot about space that amazes and sometimes frightens. Let's take a little closer look at some interesting facts about space and the Universe.
- Every year about forty new stars are born in our Galaxy. How many of them appear in the entire Universe is difficult to even imagine the answer to this question.
- There is silence in space because there is no medium for sound to propagate. So those who like to remain silent would probably like space.
- Man first looked at space through a telescope about four centuries ago. It was, of course, Galileo Galilei.
- Surprisingly, in space all the flowers we know will smell completely different. And all because the smell of a flower depends on many different environmental factors.
- An interesting fact about space and planets is that the sun is approximately one hundred and ten times larger than the earth. It is even larger than Jupiter, which, as is known, is the giant of our solar system. But at the same time, if you compare the Sun with other stars in the Universe, it turns out to be incredibly tiny. For example, the star Canis Major is one and a half thousand times larger than the Sun.
- The first earthly creature in space was the dog Laika, which was launched into space on Sputnik 2 in 1957. The dog died on the ship due to lack of air. And the satellite itself burned up in the Earth’s atmosphere due to a violation of its orbit.
- The first man in space is Yuri Gagarin. With a slight delay after Gagarin, Alan Shepard, an American astronaut, flew into space.
- The first woman in space is Valentina Tereshkova.
- Most of the atoms that make up human bodies were formed during the melting of stellar mass.
- On Earth, due to the presence of gravity, the flame tends upward, but in space it spreads in all directions.
- A person will never be able to reach the edge of the Universe, since in space there is a curvature of space, due to which a person, constantly moving in a straight direction, will eventually return to the starting point. Scientists are not yet able to fully explain this.
- On average, the distance between stars is thirty-two million million kilometers.
- An interesting fact about black holes in space is that they are the brightest objects in the Universe. In general, the gravity inside a black hole is so strong that even light cannot escape. But during its rotation, the black hole absorbs not only a variety of cosmic bodies, but also gas clouds, which begin to shine, twisting in a spiral. Meteors also begin to burn as they fall into the black hole.
- Approximately ten tons of cosmic dust fall to Earth every day.
- There are more than one hundred billion galaxies in the Universe, so there is a huge possibility that people are not alone within the boundaries of this Universe.
The most interesting facts about space can take an incredibly long time to collect and write down, since our Universe contains a huge number of secrets and mysteries, which we can now, thanks to the development of science, get at least a few steps closer to.
