The unknown mysteries of space

The study of Martian meteorites has become an entirely new area of life on Mars. As of March 27, 2017, out of 61,000 cataloged meteorites on Earth, 202 were classified as Martian meteorites. It is believed that the first Martian meteorite (Chassigny) was found during a fall in the French mountains of Ardennes in 1815. At the same time, its Martian origin was determined only in 2000. It is estimated that on average, up to 0.5 tons of Martian matter is deposited on Earth. According to other estimates, on average one Martian meteorite falls to Mars per month...

Information about Jupiter Its diameter is 11.2 times the diameter of the Earth, its volume is 1300 times larger and its mass is 317.8 times larger. The circulation period around the Sun is slightly less than 12 Earth years. Jupiter is a gas giant without a solid surface, its atmosphere consists of 90% hydrogen and 10% helium. Its core, the size of the Earth and constituting about 4% of the total volume of the planet, is solid. The rotation period around the axis is the shortest among the planets of the solar system and is just under 10 hours...

Our planet Earth is one of the nine planets of the Solar System, the fifth-largest among them and the third largest in location from the Sun, after Mercury and Venus. The solar system is located in the Milky Way galaxy, relatively far from its center. In addition to the solar system in our galaxy, there are some estimates of two hundred to four hundred billion stars in our galaxy that have their planetary systems. And all these countless cosmic bodies have one thing in common - they have a round shape or rather a ball shape...

The sun is a third-generation star. This means that solar matter has already been in the stars twice. After the Big Bang in the Universe, due to fluctuations in the density of matter, pieces of matter (compaction) were formed, which began to shrink under the influence of self-gravity. In these seals, fragmentation also began, which led to the formation of numerous galaxies that formed many clusters of galaxies. Similarly, stars formed in the galaxies, forming numerous clusters of stars within the...

Flying into space and exploring distant worlds has always been of interest to mankind. Even the most ancient civilizations made telescopes, studied the starry sky, trying to find answers to the questions of being in it. On the sky were guided and in it searched for gods. The more mankind developed, the more knowledge is gained, and the interest in space continued to grow. Having visited the Moon, of course, a man wanted to visit the planet closest to the Earth - Mars. And scientific development...

Dust is interplanetary, at least in comparative proximity to the Earth - the matter is rather studied. Filling all the space of the Solar system and concentrated in the plane of its equator, it was born mostly as a result of accidental collisions of asteroids and the destruction of comets approaching the Sun. The composition of dust, in fact, does not differ from the composition of meteorites falling on the Earth: it is very interesting to study it, and discoveries in this area have to be made a lot, but there seems to be no particular intrigue here...

We have always been fascinated by the idea of alien life in the universe. It was the basis of a huge number of fantastic stories, which were limited only by our imagination. But can there be other civilizations in the vast expanses of space or on other planets and their companions? Where are all the aliens? The sun is just one star among the billions of stars in our galaxy. Over the past few years, scientists have discovered thousands of planets around other stars, and we know that most stars have planetary systems...

The galaxy is often imagined by us as traditionally shown in encyclopedias and documentaries - a huge spiral of blue smoke, in which bunches of stars hide, in the middle of which the core shines brightly. However, such a "star island" is just one kind of correct structure. After all, there are also wrong galaxies, devoid of pronounced nuclei and sleeves - they huddle in space like an egg broken in weightlessness. So, what does it take to call an object a galaxy? First, it is the presence of stars and star clusters in it - they make up the lion's share of the visible matter of the galaxy...

Life, far from our home planet, of course, differs from the earthly one. The conditions of staying in outer space, in total weightlessness, completely change the life of astronauts. In this article, we tried to list, in our opinion, the most interesting facts from the life of people in the open universe. Astronauts tell journalists facts about space: - Almost everybody arriving in outer space experiences the so-called "space disease". This is an unpleasant sensation because the inner ear receives distorted signals...

At night, away from the blinding lights of cities, the sky reveals a fascinating picture of hundreds of stars scattered across constellations and the Milky Way. It seems impossible to count them yourself - the numbers seem fantastic, from millions to billions. But it immediately comes to mind that this is exactly what astronomers should do. So how many stars are really in the sky? Today we will try to determine the exact number. Stars visible to the eye We've heard more than once that there are trillions of stars in the visible universe alone...
