Pluto is no longer a planet to be precise, 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 of objects crossing it, it lacks mass. But this does not make Pluto less interesting object of the solar system, we will continue our acquaintance with an entertaining dwarf.

The planet Uranus, the seventh from the Sun and the fourth by 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, which makes Uranus very similar to Neptune, both planets are in the sub-category, ice giants.

Space, perhaps, is at the moment one of the greatest mysteries for all mankind. People do not get tired of exploring space, discussing it, putting forward a variety of theories, making a variety of assumptions, but still space remains something incredible, mysterious, unidentified to the end. And does it have an end that can be reached, guided by science? 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 even to imagine the answer to this question.
2. Silence reigns in space, as there is no medium for sound propagation. So those who like to be quiet would surely like space.
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 flowers we know will smell completely differently. And all because the smell of a flower depends on many of the most different factors environment.
5. An interesting fact about space and planets - the sun is about a 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 Big Dog star is 1,500 times larger than the Sun.
6. The first earthly creature in space is Laika the dog, 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 out 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, thanks to the presence of gravity, the flame tends upward, while in space it spreads in all directions.
11. A person can never reach the edge of the Universe, since there is a curvature of space in space, due to which a person, moving constantly in a forward direction, will eventually return to the starting point. Scientists have not yet been able to fully explain this.
12. The average 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, the gravity inside the black hole is so strong that even light cannot escape from there. 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 start to burn as they hit the black hole.
14. Approximately ten tons of cosmic dust falls to 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 space can be collected and written down for an incredibly long time, since our Universe contains a huge number of secrets and mysteries, which we now, thanks to the development of science, can approach at least a few steps.

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 more questions can be found in this compilation of facts about space.

Cygnus in the Constellation Cygnus is very 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.

More than 100 artificial satellites are currently launched into space every 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 Earth.

Hipparchus was the first astronomer to try to figure out the distance to the Sun.

Mars' red color is attributed to oxidized (rusty) iron on its surface.

Jupiter has no surface for spaceships to land on it because it is composed mostly of helium and hydrogen. Jupiter's gravity compresses hydrogen so hard that it turns into liquid.

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

Voyager 2 has flown 6,000,000,000 km and is moving out of the solar system after passing close to Neptune in 1989.

To conserve fuel when flying to distant planets, space probes can use the gravity of nearby planets to eject. This is called a slingshot.

Hubble's Law showed that the universe becomes 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).

The pulsars were probably created by a supernova explosion - which is why most of them are located 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, mankind has learned a lot about him, on the other, we know a tiny percentage of what actually happens in the Universe.
Today we are going to 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 annually in our Galaxy alone. 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 man 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 chunks of stone. We are separated from the nearest star by multiple light voids. And 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 located 12 billion of the same years from us! This interesting thing formed just two billion years after the Big Bang.

b) Sun more earth about 110 times. 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 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 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 writers 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 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 are also absorbed, 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 the "release" 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 the substances of Saturn 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 annually, 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. He is called Titan, and he 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 last discovery receives confirmation, 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, then the year would be two days shorter.
18. Duration of full lunar eclipse is 104 minutes, while the duration of the full solar is only something 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 would write in space. The Russians used a pencil in zero gravity without making any changes to it.

Space - greatest secret that humanity will always desire 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.
