Cool! 36
People have always thought a lot about what awaits us there, among the stars: many films and books are devoted to space exploration, but even more of those who ask - are we alone in the universe?
In fact, this is one of the most important questions in the world - is there someone else in space who looks like us, humans, or are we the only race of intelligent beings in the entire universe. Even scientists, the smartest people on our planet, cannot come to one simple answer - there are many different opinions.
The universe is very large, its exact size is not known to anyone, and due to our not very developed technologies, we can only use the methods of studying it available to us. One of them is radio signals. If we receive such a signal and decipher it, it will definitely mean that we are not alone in the universe.
And scientists really heard such a signal - with the help of the Big Ear radio telescope. This signal is called "Wow" because Dr. Aiman, who registered it, circled it with a red pen and wrote the word "Wow" in the margin. He was very surprised - and for good reason. This signal was most likely sent by some other civilization, which also did not master space very well, but already knows how radio works. The signal came from the constellation Sagittarius - maybe our future friends live there.
Space has not been studied by humanity at all - and I think that we are not alone. Scientists have recently discovered a new planetary system, in which there were as many as seven planets similar to our Earth. Yes, aliens do not live there, although maybe we have not studied them very well yet, and there is still intelligent life there, even if such as we have in the days of cavemen. But man will someday fly to these planets, which means that there are other worlds in which creatures similar to us could appear.
Some scientists say that there are no aliens because they have not contacted us yet. But in general, technologies are also poorly developed on our planet, and there was also a danger that everyone would die from nuclear weapons, which are dangerous not only for those who use them. It has very dire consequences. What if our closest space neighbors also fought, but died after using nuclear bombs? Or no one has yet arrived, because we live, for example, in a part of space in which no one flies. We have huge taiga forests in Russia, in which people also live, but it's hard to get to them. Who knows, suddenly the Earth is in the area of \u200b\u200bsuch a cosmic "taiga"?
Still, it is better to hope that we will meet with other intelligent species. Who knows, maybe aliens are already living among us, like in "Men in Black", or watching us from afar. Probably, they are waiting for us to become kinder, stop fighting and start living as one big family with our entire planet, in order to fly in and offer us friendship and peace.

Space is infinity ...
Everyone loves looking at the stars! I do not yet know a single person who would not like to do this. Living flickering lights will enchant anyone. Peering into the starry sky, everyone wants to find there some answer to their question. The night sky is a big mystery. When I look at him, I feel an impulse, a desire for something.
Even in ancient times, people were very interested in the question: "What is there, above, behind the clouds?" And without special devices, they somehow managed to study, learn, reason and guess about what the Sun and the Moon are. Many of the ancient people thought that the cosmos was a deity. They gave names to planets, worshiped them, and made sacrifices.
For a long time, humanity has gone to conquer space. At first, there were attempts to borrow wings from birds, then they came up with an aeronautical apparatus. Later, thanks to the development of science, airplanes and spaceships were built.
Every year on April 12, we celebrate Cosmonautics Day. Thisdate set to commemorate the first flight man into open space.
In our time of high technology, scientists every day are observing space, other planets and stars. In the last century alone, many discoveries have been made. Today we know about our native galaxy - the Milky Way, about the solar system, all its planets and the place of our Earth in the system, how meteorites and comets, stars and planets are formed. We must try to figure out what the universe is to the end! I would like to believe that in addition to our Earth, there is also a planet on which intelligent beings live.
It is not for nothing that people have noticed strange flying objects and glow in the sky for a long time. It is possible that these aliens want to find contact with us, to study our civilization, culture and life. Abnormal phenomena and mysterious crop circles, is it not our brothers in mind that left us messages that no one can decipher so far? Suddenly, when we look through a telescope and observe space, someone is watching us too?
In any case, we have yet to learn many more interesting secrets of the universe.
Everything unknown attracts to itself. That is why the starry sky so attracted a person. For a long time, inquisitive minds have tried to solve the riddle of the universe, to study space, the universe. Many scientists paid with their lives for their labors, since religion and science went apart. However, subsequent generations did not abandon attempts to study the mysteries of heaven.
For many centuries, humanity's interest in the sky has not dried up. The very first explorers of the starry sky were the astrologers. They were engaged in fortune telling by the position of the stars, today they are called astrologers. Science moved forward, a new branch of knowledge appeared - astronomy, which studied celestial bodies.
With the invention of new equipment - the telescope, people learned that the sun is a star, the moon is a satellite of the earth and that the earth is not the only planet. For a long time, space flight was a fantasy. Works of art about the cherished dream of progressive mankind were published, scientists tirelessly worked on the development of aircraft. And already at the beginning of the 20th century, the first rocket capable of overcoming gravity was designed.
But, unfortunately, such an important invention was left without due attention due to world wars, which significantly interfered with the development of astronautics. The dream was still a dream.
As the developing countries recovered from the aftermath of the wars, space exploration continued. The famous Soviet scientist Sergei Korolev created and launched the first artificial Earth satellite. This event became a world sensation, and soon people started thinking about sending a living being into space.
Our faithful friends, dogs, were the first visitors to space. And only then did they decide to send a person outside the Earth. April 12, 1961 will forever go down in history as the day the dream of all mankind came true. Yuri Gagarin became the first person to open the way into space. After which he became the idol of the whole world, and today everyone knows the name of this great man.
Great powers began to compete in space exploration, and a few years later the famous American Neil Armstrong entered the territory of the Moon, his first steps were followed by the whole world. And finally, a dream came true, today space flights have become regular. There is even an opportunity to visit space as a tourist. Projects for the construction of hotels in earth orbit are being created and it seems that very soon science fiction will become reality.

People are just grains of sand in a vast and immense space. Our whole life, all our affairs, problems and joys, ups and downs happen on one small ball, lonely revolving around a star. We still do not know a lot about space, years, centuries, millennia will pass and this long beautiful road into space will open for humanity. I really want to believe that it will be so.
When Yuri Gagarin for the first time in world history flew into space on the Vostok spacecraft, the world shuddered. This very great event for mankind is a significant attempt by man to pave his way into space.
Today the world has become completely different. The International Space Station with daring astronauts on board makes 16 rotations around the Earth every day. Space agencies of different countries very often launch near-earth satellites, and SpaceX plans to deliver a man to Mars by 2026!
We never stop improving our knowledge of space and the development of technologies, and someday this knowledge will reach levels that humanity cannot even dream of today. We do not have the opportunity to fly to the nearest stars, we even hardly go beyond our native Solar systems. The infinitely long and beautiful road into space is still closed for us.
To send the necessary rockets into near-earth orbit, a lot of money is needed, which is why the further development of astronautics as a whole depends on money. I think that it is necessary to look for not expensive and at the same time quite practical ways of launching space rockets and shuttles. It is a pity that the eternal problem of all mankind - the lack of funds - has also touched the space theme.
I really want to believe that there will be smart and inventive people on our planet, thanks to whom we can learn about what space hides today.
We will definitely overcome all problems, whether it is the level of technology development, price or something completely different, there can be a great many obstacles on the way to achieving the goal. Now, for the time being, we certainly lack the highest level of development of astronautics, but I believe that the genius minds of mankind will someday be able to open for us the real and long-awaited way into space.

On a clear summer night, looking into the starry sky, a person involuntarily freezes before the greatness and beauty of space. The real depth of the sky is accessible to man precisely at night, when countless placers of stars, mysterious and distant, shining in the dark.
Since ancient times, people have tried to explain what is behind the clouds, why the stars are shining, why they are falling from the sky. The world above a person's head appears huge and requires study, just like the world under his feet.
Most of the ancients considered space as a deity, gave their own names to planets and stars. People hypothesized about what this heavenly world was like. They endowed heavenly bodies with human qualities, it seemed to them that everything in the world revolves around the Earth.
So, now we think funny versions of a flat earth, a turtle and three elephants. Today we know about the place of our Earth in the solar system, and all its planets. Scientists-astronomers can look into the distant millions of world years, they know where comets and meteorites come from. It is no longer a secret how stars and planets form and how they die.
They have even begun to implement a program for the development of neighboring planets. Remember how the entire world followed the recruitment of volunteers for the Mars space exploration program Mars One? Despite the fact that there will be no opportunity to return, more than ten thousand people wanted to become pioneers. I think this is just the beginning of the cosmic odyssey of humanity.
And who knows, maybe after a while a person will be able to fly on vacation to another planet with the same ease as to another state.
Cosmonautics Day is celebrated in the world on April 12. The holiday was established in 1962 to commemorate the first human visit to outer space. The name of Yuri Alekseevich Gagarin is known to residents of all other countries. On the Vostok ship, it was the Russian representative who opened access beyond the Earth for all mankind. Gagarin's useful feat made him a legend. In Russia there are many monuments to the first cosmonaut, street names in his honor.
I really love this holiday, because it is especially significant for all our people. Cosmonautics Day makes you feel proud and unites all residents of the country.
Dozens of years after the first flight, many people have already visited outer space. Astronauts are under high stress working in dangerous conditions. All of them greatly help humanity to learn more about the Universe and conduct important research. There are many ships and stations in space now.
People's ideas about the Earth have changed a lot since antiquity, because before people did not even know that the earth was round. Astronautics even helps to study other planets.
Cosmonautics Day is celebrated every year, recalling the heroism and courage of astronauts, the work of designers and scientists.

Cosmonautics Day is one of the main spring holidays in Russia. It is customary to celebrate it on April 12, because it was then in 1961 that the Vostok-1 spacecraft flew from the Baikonur cosmodrome into the Earth's orbit, with pilot Yuri Gagarin on board.
This flight lasted only 108 minutes, but it was of colossal global significance, since for the first time a person managed to visit outer space. Therefore, the following year, at the suggestion of the pilot-cosmonaut German Titov, a holiday was officially established in the USSR in honor of this event.
Today, Cosmonautics Day is celebrated in many countries around the world, since in 2011 it was recognized as the International Day of Human Space Flight. Of course, the celebration is not accompanied by a parade and mass festivities, but, nevertheless, various thematic events are often organized on April 12.
In our country, they are predominantly educational in nature. Every year in libraries, planetariums, concert halls and parks, various lectures, master classes and seminars are held on the history of the exploration of extraterrestrial space. The museums also organize scientific and educational exhibitions.
Foreign states have their own tradition of celebrating Cosmonautics Day. In many countries on April 12, a party called "St. George's Night" is held. This event is attended not only by residents of various cities, but also specially invited famous personalities, for example, the famous science fiction writer Ray Bradbury, space tourist Dennis Tito or the actors of the Star Trek series.
I think that such events are good because they increase the interest of the younger generation in the history of astronautics. I myself am pleased to visit various installations organized on April 12, and I love to listen to stories about how the first rockets and equipment for astronauts were created.
