Discoveries and interesting facts about space, astronomy and astrophysics. Popular science articles about space. The best space photographs and only the facts.

Pluto is now not a planet to be precise, its scientists attributed it to dwarf planets, due to the fact that after clarifying the term what a planet is, Pluto turned out to be unable to clear its orbit from objects crossing it, it lacks mass. But this does not make Pluto a less interesting object in the solar system, let's continue our acquaintance with an entertaining dwarf.

The planet Uranus is the seventh from the Sun and the fourth in mass, belongs to the category of giants. If we compare the size of Uranus with other planets, then in this competition it will take an honorable third place. It is worth noting that scientists have identified due to the abundance of ice in various modifications on the planet, than Uranus is very similar to Neptune, both planets are in a sub-category, ice giants. What is mysterious about the ice giant, what interesting facts and features of its structure does it hide?

First, let's figure out what Enceladus is and what it is eaten with.

Space, perhaps, is currently one of the biggest mysteries for all mankind. People do not get tired of exploring the cosmos, discussing it, putting forward a wide variety of theories, building a wide variety of assumptions, but still the cosmos remains something incredible, mysterious, unidentified to the end. And does it have an end that can be reached, guided by science? Most probably not. Probably, the cosmos throughout the entire existence of mankind will, to one degree or another, remain a mystery, an unsolvable mystery, like a huge Sphinx, the question of which cannot be answered. But still they study it, and therefore we know a lot about space, which amaze and sometimes frighten. Let's take a closer look at some interesting facts about space and the universe.

1. About forty new stars are born in our galaxy every year. How many of them appear in the entire universe - it is difficult to even imagine the answer to this question.
2. Silence reigns in space, since there is no medium for sound to propagate. So for those who like to be silent, space would certainly be to their liking.
3. For the first time, man looked at space through a telescope about four centuries ago. It was, of course, Galileo Galilei.
4. Surprisingly, in space, all the flowers we know will smell completely different. And all because the smell of a flower depends on many of the most various factors environment.
5. An interesting fact about space and planets is that the sun is about one hundred and ten times larger than the earth. It is even larger than Jupiter, which is known to be the giant of our solar system. But at the same time, if we compare the Sun with other stars in the Universe, then it will turn out to be incredibly tiny. For example, the star Canis Major is one and a half thousand times larger than the Sun.
6. The first terrestrial creature in space is the dog Laika, which was launched in 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.
7. The first man in space is Yuri Gagarin. With a slight delay after Gagarin, Alan Shepard, an American cosmonaut, flew into space.
8. The first woman in space is Valentina Tereshkova.
9. Most of The atoms that make up human bodies were formed during the melting of stellar mass.
10. On Earth, due to the presence of gravity, the flame tends to rise in an upward direction, but in space it spreads in all directions.
11. A person will never be able to reach the edge of the universe, since there is a curvature of space in space, because of which a person, moving constantly in a straight direction, will eventually return to the starting point. Scientists are not yet able to explain this to the end.
12. On average, the distance between stars is thirty-two million million kilometers.
13. An interesting fact about black holes in space is that they are the brightest objects in the universe. In general, gravity inside a black hole is so strong that even light cannot escape from it. But during its rotation, the black hole absorbs not only a variety of cosmic bodies, but also gas clouds, which begin to shine, spinning in a spiral. Meteors also start to burn when falling into a black hole.
14. Approximately ten tons of cosmic dust falls on Earth every day.
15. 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 the cosmos can be collected and written down for an incredibly long time, since our Universe contains a huge number of secrets and mysteries, to which we can now, thanks to the development of science, come at least a few steps closer.

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 will happen if you fall into black hole? Answers to these and whole line other questions you can find in this collection of facts about space.

Cygnus in the constellation Cygnus, is very a big 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 has no surface spaceships to land on it because it is 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.

The 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 - small little green men).

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

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.

4. Our solar system is terribly boring. If you think about our neighbors, they are all unremarkable gas balls and pieces of stone. Multiple voids of light separate us from the nearest star. In the meantime, other systems are full of amazing stuff.

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) Sun more earth somewhere in 110 times. It is even larger than the giant of 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 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) Fiction authors 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, 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 last discovery will be 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 the full lunar eclipse is 104 minutes, at a time when the duration of a full sun 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.

Space - the greatest secret which mankind will always desire 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.
