Today we will look at some of the most interesting facts about space.
1. It turns out that our satellite - the Moon - moves away from us every year by about 4 cm. This depends on the decrease in the rotation period of the planet by 2 miles of a second per day.
2. Forty new stars are born every year in our Galaxy alone. It’s hard 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 whether space is infinite or just gigantic.
4. Our solar system is terribly boring. If you think about our neighbors, they are all unremarkable balls of gas and pieces of stone. Multiple light voids separate us from the nearest star. Meanwhile, other systems are full of all sorts of amazing things.
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 the same 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 even bigger than a giant our system - Jupiter. However, if you compare it with other stars in the Universe, our luminary will take a place in the manger 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 occupy more than a pixel of this star. This giant is 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 authors have fantasized about five different types 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, in every sense of the word. As you know, carbon needs very little to turn into a diamond; in this case, the conditions coincided in such a way that one of the planets hardened, and it turned into a jewel on 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 noticeable 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 due to 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. This is exactly how much time, and no less, it takes for photons to break through from the center to the surface. But after “liberation” they need only 8 minutes to get to the surface of the Earth.
7. We fly in 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 “fall” on our heads every day.
9. There are more than 100 billion galaxies throughout the Universe. There's a chance we're not alone.
10. Interesting fact: every day about 200 thousand meteorites fall on our planet!
11. The average density of Saturn's substances is two times less than the density of water. This means that if you put this planet in a glass of water, it will float on the surface. You can check this only, of course, if you find the corresponding glass.
12. The sun “loses 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 we wanted to get by car to the nearest star after the Sun - Proxima Centauri, then at a speed of 96 km/h it would take us about 50 million years.
14. Even on the Moon there are earthquakes, which are called moonquakes. But, nevertheless, in comparison with 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 fireworks display.
15. The neutron star is considered the strongest magnet in the entire Universe. Its magnetic field is millions of billions of times greater than that of our planet.
16. It turns out that in our solar system there is a body that resembles our planet. It is called Titan, and it is a satellite of the planet Saturn. It also has rivers, seas, volcanoes, dense atmosphere, 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 weights of these celestial bodies is equal to the ratio of the weights of the Earth and the Sun.
Still, intelligent life on Titan is not even worth looking for, because its reservoirs are let down: they consist mainly of propane and methane. But still, if the latest discovery is confirmed, then it will be possible to say that primitive forms of life exist on Titan. Beneath Titan's surface there is an ocean that is 90% water, the remaining 10% may be complex hydrocarbons. There is an assumption that it is this 10% that can give rise to the simplest bacteria.
17. If the Earth rotated around the Sun in the opposite direction, the year would be two days shorter.
18. Duration of full lunar eclipse is 104 minutes, while the duration of full sun is only no more than 7.5 minutes.
19. Isaac Newton first outlined the physical laws that govern artificial satellites. They were first published in the work “Mathematical Principles of Natural Philosophy” in the summer of 1687.
20. The funniest fact! The Americans spent more than one million dollars to invent a pen that could write in space. The Russians used a pencil in zero gravity without making any changes to it.
Space is the greatest mystery that humanity will always want to unravel. It attracts with its 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.
The visible Universe has a radius of 14 billion light years, and therefore the age of the Universe is about 14 billion years. Light from more distant objects simply did not have time to reach us. For this reason, everyone in the Universe will find themselves in the middle of their visible Universe. It is also difficult to find out the exact scale of the Universe because the Universe is expanding. Those galaxies that we see near the edge of the visible Universe emitted their light when they were much closer to us, and now they are much further away.
The true size of the Universe is probably much larger than the visible Universe. The geometry of the universe suggests that it can be of infinite size and that it will expand forever. Even if the Universe is not infinite, the Universe visible to us must represent a tiny part of a much larger whole.
On January 27, 1967, an international document was signed that formed the basis of space law and declared Space the property of all mankind. And for this day we have prepared for you a selection of the most amazing facts about the universe
1. A day on the planet Venus lasts longer than a year. And all because this planet rotates around the Sun noticeably faster than around its own axis.
2. It is much easier to hide emotions in space, because due to the lack of gravity, it is simply physically impossible to cry there.
3. There is no wind on the Moon, so any trace left there will remain for centuries and even millennia.
4. The larger the planet, the stronger the force of gravity on it. So if on Earth a person weighs 60 kilograms, then on Jupiter (whose radius is more than 10 times the radius of the Earth) his weight would already be 142 kilograms.
5. The density of Saturn is almost half that of water. It turns out that if such a huge glass of water could be found, Saturn would float on its surface.
6. If you connect two metal parts in space, they will instantly weld to each other. On Earth, this is hindered by oxides that form on the surface of metals under the influence of our atmosphere.
7. Every year the Moon moves away from the Earth by almost four centimeters.
8. Due to the lack of atmosphere, all shadows on the Moon are completely black.
9. Anyone who is sure that there is nothing valuable in the outer space surrounding our planet should change their minds. In 2011, scientists discovered the planet PSR J1719-1438 b, almost entirely composed of diamond.
10. Lightning often occurs in space; scientists observe them on Mars and Saturn. In most cases, “black holes” are to blame for their appearance.
11. Everyone knows that falling stars visible from the Earth are actually meteors burning up in the Earth’s atmosphere. But the stars themselves can also move, just very, very rarely; This happens to only one celestial body out of a hundred million.
12. The water discovered on Mars is heavier than that on Earth: it contains five times more deuterium, an isotope of hydrogen with an additional neutron.
13. It has been proven that there is no magnetic field on the Moon. However, the stones brought by the astronauts from the satellite had magnetic properties.
14. If even a tiny amount of solar matter (for example, the size of pin head), it would begin to absorb oxygen at such an incredible speed that it would destroy all life within a radius of 160 kilometers in less than a second!
15. The largest of known to mankind volcanoes located on Mars. The giant named “Olympus” has a length of more than 600 kilometers, and its height is 27 kilometers. Which means it's three times higher highest point earth - Mount Everest.
16. The solar energy that warms us and gives us life originated in the solar core 30,000 years ago. She spent all these years trying to overcome the super-dense shell of the heavenly body.
17. Venus is the only planet solar system, which turns counterclockwise.
18. Official scientific theory asserts that man is able to survive outer space without a spacesuit for as much as ninety seconds, but only if all the air is immediately exhaled from the lungs.
19. Scientists from Harvard University have proven that some of the Earth's rocks are of Martian origin. True, a very small part: only 0.67 percent.
20. Earth's gravity makes us lower: in outer space, the human spine “unclamps” by more than five centimeters.
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, 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 - moves away from us every year by about 4 cm. This depends on the decrease in the rotation period of the planet by 2 miles of a second per day.

Space is the greatest mystery that humanity will always want to unravel. It attracts with its 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.
Interesting Facts about space, as a rule, attract a lot of readers around the world. The secrets and mysteries of the Universe cannot but excite our imagination. What is hiding there, high, high in the sky? Is there life on other planets? How long does it take to get to a neighboring galaxy?
Agree, everyone wants to get answers to these questions, regardless of age, gender or, say, social status. This article will tell you about the most interesting facts about space and astronauts. Readers will learn a lot of new things about what they had no idea about before.
Section 1. The tenth planet of the solar system
In 2003, another tenth planet orbiting the Sun was discovered behind Pluto. She was named Eris. This became possible thanks to the development modern technologies, several decades ago, scientists did not know about such interesting facts about space and planets. Later, it was also possible to determine that beyond Pluto there are other natural ones, which, according to the decision of specialists, together with Pluto and Eris, began to be called transplutonian.
The interest of scientists in newly discovered planets is determined not only by the desire for space in close proximity (by cosmic standards) to planet Earth. It is very important to determine whether the new planet can accommodate people if necessary. It is also important to assess what dangers a new object poses for the continuation of life on Earth.
Some space researchers believe that interesting facts about space in general and studying the features of the tenth planet in particular can help in solving mysteries associated with unidentified flying objects, the presence of earth's surface grandiose structures, as well as giant crop circles that have not found a real explanation.
Section 2. Mysterious companion Moon
Does the Moon, so familiar to all earthlings, really hold many secrets? Indeed, the most interesting facts about space indicate that the satellite of planet Earth is fraught with many mysterious things. We list just some questions for which there are no answers yet.
- Why does the moon have such big sizes? There are no other natural satellites in the Solar System comparable in size to the Moon - it is only 4 times smaller than our home planet!
- How can we explain the fact that the diameter of the moon's disk during a total eclipse perfectly covers the solar disk?
- Why does the Moon rotate in an almost perfect circular orbit? This is very difficult to explain, especially if you keep in mind that the orbits of all other natural satellites known to science are ellipses.
Section 3. Where is the Earth's twin located?
Scientists claim that the Earth has a twin. It turns out that Titan, which is a satellite of Saturn, is very similar to our home planet. Titan has seas, volcanoes and dense air envelope! Nitrogen in Titan's atmosphere is exactly the same percentage as on Earth - 75%! This is an amazing similarity that undoubtedly requires a scientific explanation.
Section 4. The Mystery of the Red Planet
The red planet of the solar system, as is known, is called Mars. Conditions suitable for life - the composition of the atmosphere, the possibility of the presence of bodies of water, temperature - all this indicates that the search for living beings on this planet, at least in a primitive form, is not promising.
It has even been scientifically confirmed that there are lichens and mosses on Mars. This means that the simplest forms of complex organisms exist on this celestial body. However, it is very difficult to advance in its study. Perhaps the main problematic factor is the large natural obstacle to direct study of this planet - astronaut flights are still very limited due to imperfect technology.
Section 5. Why flights to the Moon stopped
Many interesting facts about space flights are related to our natural satellite. Americans landed on the Moon, Russian and Eastern specialists are exploring it. However, mysteries still remain.
After a successful flight to the Moon and landing on its surface (if, of course, these facts really took place!) the program for studying the natural satellite was practically curtailed. This turn of events is puzzling. Really, what's the matter?
Perhaps some understanding of this problem comes if we take into account the statement of the American who visited the Moon, that it is already occupied by a form of life in the fight against which humanity has no chance to survive. Unfortunately, the general public knows virtually nothing about what scientists actually know.
Despite the fact that flights of spaceships with astronauts to the Moon have ceased, the secrets of this extraordinary satellite invariably attract the attention of researchers on Earth. The unknown has an attractive force, especially if the object is in close proximity, by cosmic standards.
Section 6. Space toilet
Creating life support systems that function effectively in zero gravity conditions is a very difficult task. The sewage system must operate uninterruptedly, ensuring the storage of biowaste and its timely unloading as usual.
When the ship takes off and goes into space, there is nothing left to do but use special diapers. These means provide temporary, but very noticeable comfort.
Interesting facts about the first manned flight into space indicate that initially great importance was attached to the creation of plumbing fixtures for astronauts. great importance. Particular attention was paid to the individual anatomical characteristics of the crew members. Currently, the approach to equipping the sanitary zone of a spacecraft has become more universal.
Section 7. Superstitions on board
It should be noted that interesting facts about space and astronauts cannot but affect such everyday ordinary life moments, such as traditions and beliefs.
Many people note that astronauts are very superstitious people. This statement will cause confusion for many. Is this really true? In fact, astronauts behave in such a way that it seems as if they are very suspicious people. Be sure to take a sprig of wormwood on the flight, the smell of which reminds you of native Earth. When Russian spaceships take off, they always play the song “Earth in the Porthole.”
Sergei Korolev did not like launches on Monday and even postponed the launch to another date, despite conflicts on this matter. He did not give clear explanations to anyone. When the astronauts finally began to take off on Monday, by a fatal coincidence, a number of accidents occurred (!).
October 24 is a special date associated with the tragic events at Baikonur (the explosion of a ballistic missile in 1960), therefore, as a rule, no work is carried out at the cosmodrome on this day.
Section 8. Unknown interesting facts about space and Russian cosmonautics
The history of the development of Russian cosmonautics is a bright series of events. It is wonderful that scientists, designers and engineers managed to achieve success. But, unfortunately, there were also tragedies. Space exploration is an extremely complex field that involves working in extreme conditions.
For those who value the history of space exploration, information is valuable both about significant achievements in the development of the space industry and about seemingly small and even valueless facts.
- How many people know that the monument to Yuri Gagarin in Star City has one interesting feature- V right hand the first cosmonaut caught a daisy?
- Surprisingly, the first living creatures to go on a space journey were turtles, and not dogs, as is commonly believed.
- To mislead the enemy, in the 50s of the 20th century, 2 cosmodromes were built - a wooden imitation and a real structure, the distance between which was 300 km.
Section 9. Fun discoveries and interesting facts about space for children and adults
Discoveries in the space industry that become public are sometimes of a humorous nature, despite their real scientific value.
- Saturn is a very light planet. If you imagine that you can conduct an experiment with its immersion in water, you will be able to observe how this amazing planet will float on the surface.
- The size of Jupiter is such that inside this planet you can “place” all the planets that rotate in their orbits around the Sun.
- A little-known fact - the first star catalog was compiled by the scientist Hipparchus in 150 BC, very far from us.
- Since 1980, “Lunar Embassy” has been selling areas of the lunar surface - to date, 7% of the lunar surface has already been sold (!).
- To invent a fountain pen that could be used to write in zero gravity, American researchers spent millions of dollars (Russian cosmonauts use it in spaceship in flight I use a pencil to write, and no problems arise).
10. NASA's most unusual statements
At the NASA center, one could repeatedly hear statements that were perceived as unusual and surprising.
- Outside the conditions of Earth's gravity, astronauts suffer from "space sickness", the symptoms of which are pain and nausea due to distorted functioning of the inner ear.
- The fluid in the astronaut’s body tends to the head, so the nose becomes clogged and the face becomes puffy.
- A person's height in space becomes greater as the pressure on the spine decreases.
- A person who snores under earthly conditions in conditions of weightlessness in his sleep does not make any sounds!
Incredible facts
Sometimes it's very hard to imagine how huge is space.
We can only observe a small part of the Universe, and the Earth is just a small stage in the vastness of outer space.
Here are some interesting facts about space that may make you think about your place in this world.
1. The Sun makes up 99.8 percent of the mass of the Solar System.
Namely 1,989,100,000,000,000,000,000,000,000,000 kg. All other planets, satellites, asteroids and other matter, including all people on Earth, fit into the remaining 0.2 percent.
2. The gas cloud in the constellation Aquila contains enough alcohol to create 200 septillion liters of beer.
The amount of ethanol was measured in 1995, and scientists found 30 others chemical substances in the cloud, but alcohol was the main one.
3. We have discovered more than a thousand planets outside the solar system over the past 20 years.
On this moment 1822 planets have been confirmed to exist.
4. The sound of interstellar space sounds eerie
The Voyager 1 spacecraft recorded the sound of vibrating dense plasma in interstellar space in 2012 and 2013. This is what it sounds like.
Planets of the Solar System
5. All the planets of the solar system could fit between the Earth and the Moon.
Distance between the Earth and the Moon (384,440 km) – [Diameter of Mercury (4879 km) + diameter of Venus (12,104 km) + diameter of Mars (6771 km) + diameter of Jupiter (138,350 km) + diameter of Saturn (114,630 km) + diameter of Uranus (50,532 km) + diameter of Neptune (49,105 km)] = 8069 km
6. It takes an average of 170,000 years for a photon to travel from the Sun's core to the surface.
But only 8 minutes to reach Earth.
7. We won't be able to hear any sounds in space.
Voyager attempted to record the sound of interstellar space using a plasma wave instrument, but since the gas in interstellar space is less dense, we will not be able to hear the sound ourselves.
If a sound wave were to pass through a large cloud of gas in space, just a few atoms per second would reach the eardrum and we would didn’t hear the sound because our eardrum is not sensitive enough.
8. Saturn's rings disappear from time to time.
Every 14-15 years, Saturn's rings turn edge-on towards the Earth. They are so narrow compared to how big Saturn is that they appear to disappear.
9. Saturn has an additional huge ring, discovered only in 2009.
The ring starts about 6 million kilometers from Saturn and extends 12 million km, which would accommodate 300 Saturns. Saturn's moon Phoebus orbits inside the ring and some astronomers believe that it is the source of the ring.
10. There is a hexagonal cloud at the north pole of Saturn.
The hexagonal vortex extends almost 30,000 km across.
11. In our solar system there is an asteroid with rings like Saturn.
The asteroid Chariklo has two dense and narrow rings. This fifth object in the solar system to have rings, along with Saturn, Jupiter, Neptune and Uranus.
12. Jupiter is 2.5 times more massive (heavier) than all the planets of the solar system combined.
Its weight is equal to the weight of 317.8 planets like Earth.
13. In an hour and a half, more solar energy hits the Earth than we used in the entire year 2001.
14. If you fell into a black hole, you would be stretched out like a noodle.
The phenomenon is called spaghettification.
15. If nothing disturbs the Moon (for example, a meteorite), then the traces left on its surface will remain untouched forever.
Unlike Earth, there is no erosion caused by wind and water.
16. A star was recently discovered that had been hidden in the glare of a supernova for 21 years.
The star and its companion, which exploded and hid it from view, are located in the M81 galaxy, located 11 million light-years from Earth.
17. Dung beetles navigate the Milky Way.
Birds, seals and humans use the stars to navigate, but African dung beetles use an entire galaxy rather than individual stars to make sure they move in a straight line.
18. An object the size of Mars collided with Earth 4.5 billion years ago.
This is the most plausible explanation so far for how the Moon formed. A piece broke off from the object, becoming the Moon, and caused the Earth's axis to tilt slightly.
Stars of the Universe
19. We are all made of stardust.
After Big Bang, tiny particles combined to form hydrogen and helium. They then combined in the very dense and hot centers of stars to create elements including iron.
Since humans and other animals and most matter contain these elements, we can be said to be made of stardust.
20. There are countless stars in the known Universe.
We don't know how many stars there are in the Universe. For now, we use rough estimates to find out how many stars there are in our Milky Way galaxy. Multiplying this number by the estimated number of galaxies in the Universe, we can say that there are an unimaginable number of stars.
According to a study by the Australian National Institute, the number of stars is approximately 70 sextillion, and this is 70,000 million million million.
