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 actually happens in the Universe.
Today we'll take a 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 a decrease in the rotation period of the planet by 2 miles of a second per day.
2. Forty new stars are born in our Galaxy alone every year. It is difficult even to 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 of our neighbors, they are all unremarkable gas balls and chunks of stone. We are separated from the nearest star by multiple light voids. In the meantime, other systems are full of amazing stuff.
a) There is a very amazing thing in the vastness of the Universe - a giant gas bubble. Its length is about 200 million light-years, and it is 12 billion of the same years from us! This interesting thing was formed only 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 star will take a place in the nursery school, this is 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 more than a pixel of this star. This giant has VY Big dog, the diameter of which is about 3 billion km. How and why this star was blown to such dimensions, no one knows.
c) Science fiction authors 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 the 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 jewel of a universal scale.
5. Black hole is the brightest object in the entire universe.
Inside a black hole, the force of gravity is so great 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, gas clouds also absorb, 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 heavenly body was formed in the core of the Sun about 30 thousand years ago. This is exactly how much time and no less is needed 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 in 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 that we are not alone.
10. An 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, then 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 at a speed of 96 km / h, it would take about 50 million years.
14. Even on the moon earthquakes occur, which are referred to as moonquakes. But, nevertheless, in comparison with earthly ones, they are insignificant 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 strongest magnet in the entire universe is the neutron star. Its magnetic field is millions of billions of times larger than the field 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, 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 celestial bodies is equal to the ratio of the weight of the Earth and the Sun.
Still, intelligent life on Titan is not even worth looking for, because its reservoirs were let down: they consist mainly of propane and methane. But still, if the last discovery is confirmed, then it will be possible to assert that primitive life forms exist on Titan. There is an ocean under the surface of Titan, which is 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, 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 7.5 minutes.
19. Isaac Newton was the first to outline 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! Americans have spent more than one million dollars to invent a pen that would 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 pulls with its extraordinary properties and riddles. Today we have revealed nothing at all, but I hope that the Universe has become more accessible and interesting for you.
