The most interesting thing about space

Space- the most discussed and, with it, 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 look at some of the most interesting facts about space.

It turns out that our satellite, the Moon, is about 4 cm away from us every year. It depends on reducing the period of rotation of the planet by 2 miles per day.

Every year, forty new stars are born only in our Galaxy. It is difficult to even imagine how many of them appear in the entire Universe.

The universe has no limits. It seems that everyone is familiar with this statement. In fact, no man knows whether the cosmos is infinite or just gigantic.

All stars, galaxies and black holes in the Universe make up only 5% of its mass. It's amazing, but 95% of the mass is innumerable. Scientists decided to call this mysterious substance "dark matter" and to this day no one can precisely determine its character.

Our solar system is terribly boring.If you think about our neighbors, then they are all not remarkable gas balls and pieces of stone. From the nearest star we are separated by multiple light voids. And between this, in other systems is full of all kinds of amazing stuff.

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 from us in 12 billion of those same years! This interesting thing was formed only two billion years after the Big Bang.

The sun is 110 times bigger than Earth. It is even more than the giant of our system - Jupiter. However, if we compare it with other stars in the Universe, our star will take its place in the nursery of a kindergarten, so this is so little.
Now let's imagine a star that is more than 1500 times our Sun. Even if we take the entire Solar System, it will not take more than a pixel of this star. This giant is called the VY Big Dog, whose diameter is about 3 billion km. How and why this star was blown to such dimensions, no one knows.

Fantasy authors have imagined about five different types of planets. It turns out that these species are hundreds of times larger. 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 just a little, to turn into a diamond in this case, the conditions coincided so that one of the planets hardened and turned into a treasure of the universal scale.

The black hole is the brightest object in the entire Universe.
Inside the black hole, the force of gravity is so great that it is impossible to escape from it, even the light. According to the logic of things, the hole should not be visible in the sky at all. However, during the rotation of the hole, in addition to the cosmic bodies, gas clouds also absorb, which begin to glow, twisting in a spiral. Also meteors, getting into black holes, light up from incredibly sharp and fast movement.

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. It is this much time and not less that photons need to make their way from the center to the surface. But after the “liberation” they need only 8 minutes to get to the surface of the Earth.

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 is flying in space at a speed of 300 km per second.

About 10 tons of cosmic dust “fall” on our heads every day.

There are over 100 billion galaxies in the entire universe. There is a chance that we are not alone.

Interesting fact: every day on our planet falls about 200 thousand meteorites!

The average density of substances of Saturn is two times less than the density of water. This means that if you drop this planet into a glass of water, it will float on the surface. You can check it, only, of course, if you find the corresponding glass.

The sun "loses weight" at 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.

If you wanted by car to get to the nearest star after the Sun - Proxima Centauri, then at a speed of 96 km / h, we would need about 50 million years.

Even on the moon earthquakes occur, which are referred to as moonquakes. But, nevertheless, in comparison with the earth, they are negligible weak. Each year, there are more than 3,000 such moonquakes, but this total energy would be enough only for a small salute.

The strongest magnets in the entire universe is considered to be a neutron star.Its magnetic field is millions of billions more than the field of our planet.

It turns out that in our solar system there is a body resembling our planet. He is called Titan, and he is a satellite of the planet Saturn. It also has rivers, seas, volcanoes, a 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 weight ratio of these celestial bodies is equal to the weight ratio of the Earth and the Sun.
Yet, intelligent life on Titan is not even worth looking for, because, as its reservoirs have failed, 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. Under the surface of Titan, there is an ocean, 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.

If the Earth rotated around the Sun in the opposite direction, the year would be two days shorter.

The duration of a total lunar eclipse is 104 minutes, at a time when the duration of full solar is just not more than 7.5 minutes.

Isaac Newton first outlined the physical laws governing artificial satellites.They were first published in the work "Mathematical Principles of Natural Philosophy" in the summer of 1687.

The funniest fact! Americans spent more than one million dollars to invent such a pen that they would write in space. The Russians used pencil in zero gravity without making any changes to it.

In the orbit of our planet is a dump from the waste of cosmonautics. More than 370,000 objects weighing from a few grams to 15 tons orbit around the Earth at a speed of 9,834 m / s, colliding between themselves and flying into thousands of smaller parts.

The main contender for the title of the inhabited planet of the extrasolar system, the “Super-Earth” GJ 667Cc, is located only 22 light years from Earth. However, the journey to it will take us 13,878,738,000 years.

The nearest galaxy to us, Andromeda, is at a distance of 2.52 million years. The Milky Way and Andromeda move towards each other at tremendous speeds (Andromeda’s speed is 300 km / s, and the Milky Way is 552 km / s) and will most likely collide in 2.5-3 billion years.

The Cosmic Yule, called the neutron star, is the fastest spinning object in the Universe, which makes up to 500 revolutions per second around its axis.In addition, these cosmic bodies are so dense that one tablespoon of their constituent matter weighs 10 billion tons.

In space, tightly compressed metal parts are spontaneously welded. This occurs as a result of the absence of oxides on their surfaces, the enrichment of which occurs only in an oxygen-containing medium (the Earth's atmosphere can serve as a good example of such an environment). For this reason, NASA (National Aeronautics and Space Administration) is processing all metal parts of spacecraft with oxidizing materials.

Earth's gravity compresses the human spine, so when an astronaut enters space, it grows by about 5.08 cm. At the same time, his heart contracts, decreasing in volume, and starts pumping less blood. It is the body’s response to an increase in blood volume, which requires less pressure for normal circulation.

The weight of our planet is a variable value. Scientists have found that every year the Earth recovers by 40,160 tons and drops 96,600 tons, thus losing 56,440 tons.

The official scientific theory says that a person can survive in the open space without a spacesuit for 90 seconds if all the air from the lungs immediately exhales. If only a small amount of gases remain in the lungs, they will begin to expand with the subsequent formation of air bubbles, which, if they enter the blood, will lead to an embolism and imminent death. If the lungs are filled with gases, then they simply break off. After 10-15 seconds of being in open space, the water in the human body will turn into steam, and the moisture in the mouth will begin to boil. As a result, soft tissues and muscles will swell, leading to complete immobilization. This will be followed by loss of vision, glaciation of the nasal cavity and larynx, blue skin, which, in addition, will suffer from severe sunburn. The most interesting thing is that the next 90 seconds the brain will still live and the heart will beat. In theory, if, during the first 90 seconds, the unsuccessful astronaut who was exhausted in the open space was placed in a pressure chamber, then he would get rid of only superficial damage and a slight fright.

The largest meteorite that fell to Earth is considered to be the 2.7 meter long Goba (Hoba), found in Namibia.The meteorite weighs 60 tons and is 86% iron, which makes it the largest piece of iron of natural origin on Earth.

Venus is the only planet in the solar system that turns counter-clockwise. There are several theoretical justifications for this. Some astronomers believe that such a fate befalls all the planets with a dense atmosphere, which first slows down and then twists the celestial body in the opposite direction from the original, others assume that the group was caused by a group of large asteroids falling to the surface of Venus.

Contrary to popular belief, space is not a complete vacuum, but rather close to it, because 88 gallons (0.4 m3) of cosmic matter account for at least 1 atom (and as often taught in school, there are no atoms or molecules in a vacuum).

The density of 5.6846 × 1026 kg Saturn is so small that if we could put it in water, it would float on the surface itself.

On February 5, 1843, astronomers discovered a comet, which was given the name "Great" (aka the March comet, C / 1843 D1 and 1843 I). Flying close to the Earth in March of the same year, it ‘cut the sky in two with its tail, the length of which reached 800 million kilometers.The tail of Earthlings, stretching for the "Great Comet", was observed for over a month, until, on April 19, 1843, it completely disappeared from the sky.

The Mars Olympus Olympus (Olympus Mons) is the largest in the Solar System. Its length is more than 600 km, and its height is 27 km, while the height of the highest point on our planet, the peak of Mount Everest, reaches only 8.5 km.

1 plutonian year lasts 248 Earth years.

Solar matter the size of a pinhead, placed in the atmosphere of our planet, will begin to absorb oxygen at an incredible rate and in a fraction of seconds will destroy all life within a radius of 160 kilometers.
