There are many mysteries in space. Its sheer volume, along with the trillions of objects in the many billions of galaxies in the universe, is almost incomprehensible to the human brain. But among these, there are facts that only astronauts and almost no ordinary people know. Here are 5 of the most stunning of them! You will really like it!There are probably dead animals in Earthʼs orbitBefore humans entered space in 1961, animals were sent into space to test whether future astronauts could survive the flight, and if so, how the flight might affect their health.&nbsp;You will be surprised to know that in addition to dogs, chimpanzees, mice, cats, frogs, worms, turtles, and other animals were also sent there. Some of them returned safely, and some died during the return or landing. But some flew on ships that were never found. Therefore, most likely, these dead animals are still floating somewhere on spaceships.A planet of diamondsIt was discovered in 2004. Research by scientists at Yale University suggests that the rocky planet 55 Cancri e, which has twice the radius of Earth and eight times the mass, may have a surface composed of graphite and diamond. This planet is 40 light-years away from us, but it is visible to the naked eye in the constellation of Cancer. In 2016, scientists investigated that its "light" hemisphere is in a molten state, while the dark side, on the contrary, is solid. Recent density measurements have shown that 55 Cancri e is composed mainly not of oxygen, like the inner planets of the Solar System, but of carbon. So it would be interesting to visit the planet 55 Cancri e, at least to study its core.It is impossible to cry in spaceOf course, nobody forbids astronauts to cry, but they physically cannot do it. Because of weightlessness, tears cannot flow down, as on Earth. The formed tears have nowhere to go, so they do not fall from the eyes. They form a conglomerate around the eyeball and remain there if not removed.&nbsp;In space, astronauts grow by 5 centimetersThis is a vivid example of how microgravity affects the human body. And this can be explained by the following example: when a force acts on the spring, it is compressed. When this does not happen, it stretches. The spine can also extend up to 7.6 centimeters in space, where gravity is very weak. But when the astronauts return to Earth, their height returns to normal.Space is absolutely silentIt is hard to believe, but the fact is that sound needs an environment in which it can move and sound. And since there is no atmosphere in the cosmic vacuum, no melody can be heard there. Only complete silence.Of course, these are far from all sensational discoveries from NASA. You can learn more about them in our next articles. We are sure that on our pages you will find the most exclusive information from around the world.&nbsp;

Sensational 5 facts about space that only astronauts can tell

About one and a half thousand thunderstorms, accompanied by thunder and lightning, rumble on our planet every minute. But there is a country where this happens most often, and there is a country in which this natural phenomenon does not happen for several years. Of course, at first glance, this may seem like an impossible fact, but nature has its whims.You have probably noticed the fact that thunderstorms almost always occur in the warm season when the temperature of the air above the ground rises. However, snow storms also occur in winter once every few decades. This is a very rare phenomenon because the formation of a thunderstorm requires the coincidence of a very large number of meteorological conditions.When an electric storm rages outside the window, you donʼt want to leave the house. And this is the right decision because thunder is usually accompanied by strong winds, heavy downpours, and lightning discharges, so leaving the house can be simply dangerous. You probably didnʼt know that the most powerful tornadoes, the rotation speed of which can, in theory, be supersonic, are formed precisely under a thunderstorm front. And the energy produced during a thunderstorm is comparable to a powerful nuclear bomb explosion. But this is only science.If you are very afraid of thunderstorms, you will be interested to know where they donʼt exist. The only places on our planet where this natural phenomenon does not exist are the North and South Poles. That is because an important ingredient for thunderstorm development is a flow of rising moist air that condenses into precipitation particles that generate electrical charges sufficient to trigger lightning, an ingredient that is noticeably absent at the poles.But in addition to these parts of the world, there is also a country where there are almost no thunderstorms. And this is Egypt. This country generally has fairly stable weather conditions all year round, except for winter. This natural phenomenon in this country can happen once every few years.There is another interesting fact related to the Australian Tiwi Islands. Due to the coincidence of several weather conditions, a storm cloud first forms above them and then disappears. This allows pilots of local airlines to use such a phenomenon as a reference point.But most often thunderstorms happen in Argentina. Because the Andes mountains help to lift warm, moist air coming from the north (from the Amazon Basin), which collides with cooler, drier air, from the south, promoting the formation of powerful storms.Also, most lightning occurs over Lake Maracaibo. Such a conclusion was reached by climatologists from the United States and Brazil, who observed thunderstorms on Earth from a satellite for 16 years.Well, nature is a great inventor. But remember that a thunderstorm is one of the most dangerous natural phenomena. Therefore, you should be very careful when you see that it is about to come.If you would like to know more facts about natural phenomena, read our articles.
