20-facts-about-space-that-will-surprise-you-no-less-than-the-rain-in-january

Scientists have revealed the secrets of stars and planets by exploring outer space. Many objects were at first simply mathematically calculated in theory, and when powerful telescopes were invented, these facts were confirmed. Now people have the technical ability not only to photograph amazing space phenomena, but also to understand how everything works with the help of space probes.

 

We have collected cosmic facts to prove that the Universe is much more mysterious than it seems

 

We at Bemorepanda have put together a good dose of scientific space facts for you to show how our Universe is both an amazing and strange place in space.

 

1. The Perseverance rover is looking for signs of life on the Red Planet

NASA's Perseverance landed on the most intriguing planet in the solar system, Mars, two years ago. This happened in February 2021. The task of "Perseverance" is to collect data to answer the question: did someone live on the planet before it became a lifeless desert.

 

The rover is drilling and collecting rock samples, looking for signs of microbial life, testing oxygen production for further human colonization of the planet.

 

Perseverance traveled 211 million km of outer space before successfully landing on the surface of Mars. It took him 7 months of Earth time to do this. NASA plans that the collected samples, which the rover is stockpiling in caches, will be brought back to Earth by follow-up missions in the 2030s.

 

2. A huge cloud of water floats in space

Astronomical observations in 2011 led to a striking conclusion: at a distance of about 12 billion light-years from our Earth, there is a huge accumulation of water vapor in outer space.

 

This is the largest cloud that is known to mankind. It appeared at an early stage of the origin of the Universe, when its age was about 1.6 billion years. Therefore, this accumulation of water vapor in space is also the oldest of all known to astronomers.

 

To imagine its size, you need to try to mentally increase our entire water supply, which is located in the oceans and seas of the Earth, by 140 trillion times. It is unlikely that this will work for an ordinary earthling. But that's not all, here's a little more coolness.

 

Astronomers believe that this grandiose accumulation of steam is nothing more than a source of energy for the life and growth of a black hole. If there is enough carbon monoxide in the form of gas in the cloud, then the black hole has every chance to increase in size by six times with all the ensuing consequences - black holes absorb matter irrevocably!

 

3. Jupiter's Great Red Spot Is Shrinking

The planet Jupiter is a gas giant, which is an accumulation of hot gases. Jupiter's calling card is its Great Red Spot, or GRS (Great Red Spot), which is nothing more than a high-pressure storm raging on the planet - a giant storm, or rather a cyclone.

 

This phenomenon lasts for 300 years, and once its area was three times the diameter of the Earth. But astrophysicists are seeing a gradual contraction of the Great Red Spot, which is getting narrower. Now the dimensions of the GRS are 8000 miles (about 13 thousand km). But you can not worry about the complete disappearance of the Red Spot - it becomes smaller in width, but grows in height.

 

4. Black and white moon of Saturn

Not one moon revolves around Saturn, like the Earth, but as many as 53, and these are only those that received their own names. In addition to them, smaller satellites revolve near Saturn, which have not yet been honored to be named by official science.

 

The brightest and most unusual of the moons of the giant of the solar system is Iapetus, who managed to be two-faced: one of his hemispheres is dark and the other is light. This rocky fragment is small in size - its diameter is 914 miles, or about 1.5 thousand km.

 

The light side is capable of reflecting 20 times more light than the dark side, and scientists are well aware of why this happens. This area is normal ice. But why it is always dark on the other side is not entirely clear. According to one theory, another of the moons - Phoebe - shows a vindictive nature and emits a stream of particles towards Iapetus. According to a more recent theory, Saturn's two-faced moon rotates so slowly that its dark material absorbs heat and therefore darkens more and more.

 

5. Venus is the hottest planet in the solar system

It is unlikely that a human foot will set foot on Venus in the near future, because on this hot planet the average temperature reaches 450 - 462 ° C. This is enough to melt the lead, but not enough heat to melt the steel (it needs 2500°F, or 1370°C).

 

450 Celsius means that no form of life known to us today is possible on Venus. By comparison, the average temperature on Earth is only 58.6°F, or 17.8°C. Extremophile organisms can live happily on Earth at 206°F (96.7°C), but even they cannot survive on Venus.

 

At the same time, it is worth considering that the "Morning Star" is not located closer to the Sun than the rest - it is in second place after Mercury. Venus, on the other hand, has a super-dense atmosphere that can hold greenhouse gases, and therefore the planet is an uninhabitable “gas chamber”.

 

6. Amazing speed of rotation of neutron stars

The birth of neutron stars occurs at the moment of explosion and death of stars, the mass of which is 8 times greater than the Sun, and as a result of a supernova explosion. These celestial bodies are very small in size - their radius is from 10 to 20 kilometers, and their mass is about the same as that of the Sun, but they have a huge density.

 

If you theoretically weigh one teaspoon of the substance that makes up a neutron star, then the scales will show one billion tons. How much such a star will weigh as a whole is hard to even imagine, although it is possible to calculate. If people were on the surface of a neutron star, they would experience the force of gravity 2 billion times more powerful than Earth's.

 

The most amazing thing is the speed of rotation of these celestial bodies. Due to the compression of the core and a sharp decrease in inertia, the new neutron star begins to rotate very quickly - up to 43 thousand revolutions per second, however, the speed slows down over time. Astrophysicists have calculated and then discovered more than 2500 neutron stars in outer space.

 

7. A distant planet with a diamond core

Exoplanet 55 Cancer e is a celestial body in the status of a super-Earth, which is approximately twice the size of our Earth and is part of the distant planetary system of the star in the constellation Cancer. It was named Janssen and studied with the help of modern telescopes and satellites.

 

The planet is located far from us - at a distance of 40 million light years. 55 Cancri e revolves around its star in a very low orbit, making one revolution in 18 Earth days - a year there lasts a little more than two weeks! Such proximity of one side of the planet to the star leads to heating to a temperature of 2400 ° C - this is an ocean of lava on the surface. The other side heats up to 1100°C and has an atmosphere.

 

Scientists have suggested that 55 Cancer e has carbon in its depths, which, due to high temperatures and density, may well have the form of graphite and diamonds, and there are very, very many of them!

 

8. Ice space cryovolcanoes

A volcano on our planet is a geological object that spews molten and red-hot lava from its depths. In space, at low temperatures, volcanoes also operate, but they spew out frozen water, ammonia and methane, which come out in the form of steam, cryolava and volcanic snow.

 

Many cryovolcanoes have been discovered on the planets and satellites: Pluto, Triton - the satellite of Neptune, Titan - the satellite of Saturn, on Europa and Io - the satellites of Jupiter. On Io, NASA probes have detected very high activity, with plumes of frozen steam from hundreds of vents stretching horizontally for 400 km. Why cryovolcanoes erupt is still not exactly clear, researchers call the gravitational attraction of cosmic bodies the reason.

 

9. Our galaxy will collide with the next

Together with our solar system, we are hurtling through space in the Milky Way galaxy. The nearest neighboring Andromeda galaxy is a huge distance of 2.5 million light years. But the problem is that the Milky Way and Andromeda are flying at cosmic speeds towards each other, and someday a collision is inevitable, astrophysicists say. As a result, both galaxies will be destroyed, and everything we know about the world and space will disappear.

 

The speed of these star formations is 250 thousand miles per hour (402 thousand km / h), and given the enormous mass of both objects, the death of stars and planets is inevitable. As a result, what remains will be a completely different galaxy, which has nothing in common with our star-planetary system.

 

What should humanity do? You can relax a little: the collision will not happen earlier than in 4 billion years, so for now you can safely go about your business.

 

10. Space cold welding

On our planet, we connect two metal parts by welding: we heat the metal until it reaches its melting point, after which the molecules combine.

 

But in outer space, if we want to join metal parts, we don't need hot welding. No other similar steps are needed. There is a method of cold welding - when metals are connected either by compression or by shear sliding. At the same time, the protection in the form of an oxide layer is erased, which prevents the metals from merging under Earth conditions.

 

But there is no air and oxygen in space, and this layer is lost, so nothing prevents electrons from flowing from part to part, fusing them into one.

 

11. Uranus has a strong orbital inclination and a long winter.

The planets revolve around the Sun with some tilt. For example, our Earth has a tilt angle of 23 degrees. Thanks to this, we know the pronounced seasons and the change of weather - in summer the part of the planet where we live leans closer to the sun, and therefore we are warm, and in winter our territory is at a far distance, and we have cold.

 

But the ice giant Uranus has a planetary tilt "beyond". Its rotation angle is nearly 98 degrees, making its placement relative to the Sun "on its side and slightly head down". The planet makes a full revolution around the Sun in 84 Earth years, so the "season", in our understanding, here lasts 21 years, with 42 years being a polar day, the other 42 being a polar night. The winds of Uranus reach a speed of 240 m/s, and the temperature drops to minus 224 °C. In short, this planet is cold, very cold.

 

12 Largest Canyon System On Mars

Mars is already fairly well understood thanks to the advent of powerful telescopes and space probes, and NASA's Perseverance module is currently doing a detailed study.

 

This amazing planet has the largest and most extensive canyon found among the planets of the solar system, including Earth. The Mariner Valleys are a gigantic canyon system discovered by Mariner 9 back in 1972. It is 4,500 km long, ten times the length of the Grand Canyon in the United States, and covers a quarter of the entire circumference of Mars.

 

The width of the canyons reaches 600 km - this is 20 times the Grand Canyon, and the depth reaches 11 km, seven times the largest canyon on Earth. It is believed that the Mariner Valleys were formed during the formation of the planet and deepened due to erosion, and possibly the powerful giant volcanoes of the Martian province of Tharsis.

 

13. Mercury shrinks in size

It was believed that our Earth is the only planet in the solar system that continues to shrink. This is caused by tectonic activity, when the movement of lithospheric plates under the earth's crust releases energy and deforms the surface, which leads to gradual compression.

 

But now there are other data. Earth is not the only planet that is gradually shrinking in size. The smallest planet in the solar system, Mercury, as it turns out, is also in the process of warping. This was revealed by the MESSENGER spacecraft in 2016. Rock-like landforms, called fault ledges, have been discovered, which indicate that the planet is still in the formation stage, although 4.5 billion years have already passed since the creation of the solar system.

 

14. Neptune warms itself

Neptune happened to be at the farthest end of the solar system with a distance of 4.55 billion km from the Sun, so that the year on this ice giant lasts almost 165 Earth years. At the same time, Neptune is spinning as best it can - it rotates around its axis at a speed of one revolution in 16 hours.

 

It may seem that a severe cold and darkness reigns on the planet, but this is not entirely true. What is on Neptune is hurricane-force winds and storms that accelerate to 600 m / s. But if the planet does not have enough light and heat from the Sun, then you have to produce this heat on your own, which Neptune does.

 

Its internal temperature is much higher than that of Uranus, due to which weather changes occur. The exact cause is not yet known, but it is believed that the hydrogen, which is located in the depths of Neptune, increases the heat. The planet produces its own heat 2.6 times more than it can receive from the Sun, so it is terribly cold in the upper atmosphere - minus 220 °C, and inside the planet warms up to plus 7000 °C.

 

15. Saturn and its mysterious hexagon

The size of Saturn is 9.5 times larger than the Earth, and despite the fact that the planet has no solid and consists of gases, its mass is 95 times greater than that of the earth. Saturn makes one revolution around the star in 29.45 Earth years, but it turns around its axis in 10 hours 32 minutes, ranking second in terms of rotation speed after Jupiter.

 

The features of Saturn include its extraordinarily beautiful rings, consisting of particles of ice and stones, and in addition, a completely unique and amazing phenomenon - a regular hexagon located at its north pole. This is nothing more than a cluster of clouds, but scientists have not yet figured out why they took the correct geometric shape. It is only known that one side is 13800 km and four of our planets Earth can easily fit inside this formation.

 

The hexagon rotates with a period of 10 hours. 39 min., but at the same time it does not change its shape. A strong turbulent vortex is raging inside it, and this storm has been going on, according to observations, for 40 years now. Perhaps the strange shape is due to zonal jets extending downwards in high-pressure areas.

 

16. Cosmic distances are beyond imagination.

People do not even think about the fact that they live on a small planet that flies in a boundless dark space. We measure the distance using the time we spend on the move - for example, to work 30 minutes, to the store 10 minutes walk.

 

But in space, you have to measure the distance in light years. One light year is the distance that a ray of light (its speed is 300 thousand km / s) is able to overcome in one calendar year. To imagine this scale, let's take the distance from the Earth to the Moon - it will take only 1.3 seconds for the beam to travel these 380 thousand km to our satellite. It would take nine hours for a modern spacecraft to do this.

 

But if we decide to fly to our nearest star, Proxima Centauri, we will have to travel 4.246 light years (at the speed of light). The same journey in a car at a speed of about 100 km/h would take 356 billion years.

 

17. Twinkling Stars

If we look at the sky, we will find that the stars twinkle and twinkle, but the planets do not, they continue to shine with a steady light. Why it happens?

 

The explanation lies in the mobility of our planet's atmosphere. The light that the star emits enters the atmosphere and is refracted in it, which our eyes perceive as flickering. The planets seem large to us, and their reflected light is also refracted in the atmosphere, but due to the size of the planets, these distortions are compensated, as a result of which our eyes see a steady brilliance.

 

18. Temperature spread of Mercury

Even on Earth, one can encounter a large spread in the values of a street thermometer, when in summer it is plus 45 ° C in the region, and minus 30 ° C in winter. But small in size Mercury has gone much further and can greatly surprise with its temperature drops.

 

Since this planet is located closest to the Sun and the period of its revolution around the star is the shortest - only 87.97 Earth days, Mercury has no atmosphere and there has been no geological activity along with internal heat over the past few billion years, and the temperature change is significant.

 

So, at night at the equator on the surface of the planet it is minus 173 °C, during the day this area warms up to plus 427 °C. This spread is the widest among all other planets in the solar system. In the polar zones, the temperature is more stable and does not rise above minus 93 °C. If you suddenly find yourself on Mercury as a traveler, you will have to rack your brains well, choosing your wardrobe.

 

19. Planetary diamond showers

Probably, diamond planets exist somewhere, and scientists even point to these amazing celestial bodies, but they are far beyond our solar system.

 

But even among the closest neighbors of the Earth there are planets in the atmosphere of which it can rain from real diamonds. The gas giants Jupiter and Saturn are able to turn the methane they are made of into carbon black under the influence of thunderstorms raging on the surface. As the soot settles, it becomes graphite, which crystallizes into diamonds.

 

When these diamond crystals, about one centimeter in diameter, approach the red-hot core, they melt and transform into diamond liquid droplets. Thus, those astronauts who dare to take these diamonds into their pockets have very little time left.

 

20. What is more - sand or stars?

Carl Sagan said that there are more stars in the universe than there are grains of sand on the entire earth. Astronomer Bob Berman decided to check and refuted this statement. For calculations, he applied mathematical methods: he multiplied the 100 billion stars that one galaxy in our Universe has by the probable number of galaxies (which is from 200 billion to 3 trillion galaxies). Then he counted how many grains of sand are in one cubic centimeter and multiplied by the amount of sand on Earth. And what turned out? There were as many grains of sand as there are stars in the universe.

10-most-powerful-animals-on-the-planet-and-you-can-hardly-guess-the-strongest-of-them

People are most often concerned about the strength of other people, and they, as a rule, forget about animals, and in vain, since their capabilities far exceed human ones. Bemorepanda has compiled a list of the 10 most powerful animals on the planet, whose power cannot fail to impress. You can hardly guess who is at the bottom of the list, so get ready to be amazed!

 

Grizzly bear

04-16-57-1619791074350119102

Can lift objects over 500 kg, which is ~ 0.8 times their average body weight.

 

Green anaconda

04-20-53-1619805222264978696

This snake can squeeze someone to death, equal to its average weight of 250 kg.

 

Elephant

04-16-57-16197910741440678583

Elephants are the strongest mammals and the strongest land animals. The African elephant can weigh up to 6.35 tons, while it can carry up to 9 tons, which is the weight of 130 adults.

  

Musk ox

04-16-57-1619791074660630972

A musk ox can carry an object of about 900 kg, which is 1.5 times its average weight.

 

Tiger

04-16-57-16197910741749063951

A tiger can drag an object weighing about 550 kg onto a 3-meter tree. This is roughly double their average body weight.

 

Eagle

04-16-57-16197910741626433175

The eagle is the most powerful bird, capable of lifting something 4 times its own weight during flight. Moreover, they weigh up to 6 kg.

  

Gorilla

04-16-57-1619791074461713354

Gorillas can lift about 2 tons (about 30 people can lift the same amount), which is more than 10 times their average weight.

 

Leaf cutter ant

04-16-57-16197910741363043373

These ants carry things in their jaws that weigh 50 times their average weight (about 0.5 grams). It's like trying to lift a truck with your teeth.

 

Rhinoceros beetle

04-20-58-16198055211087401132

These small beetles can lift things 850 times their own weight. For comparison, if a person had the strength of a rhinoceros beetle, he could lift a 65-ton object. And if an elephant had the same strength, it could carry 850 elephants on its back.


Dung-beetle

04-16-57-1619791074653167383

The dung beetle is not only the most powerful insect in the world, but also the most powerful animal on the planet compared to its body weight. They can push objects 1,141 times their own weight. In the case of humans, this is how the average person would push six double-decker buses packed with people.

55-interesting-facts-about-asteroids

The process that helped form the planets can be called "growth". At the beginning of the formation of the Universe, the collision of two bodies usually led to the formation of one larger body. Planets and asteroids were formed in this way. Apparently, the planets have accumulated more mass than most asteroids. But as seen with Ceres, which is a dwarf planet, some asteroids are very close to reaching a mass that would create enough gravity to become planetary.


Asteroids are made from various minerals and substances. Their composition depends on the planet they did away with in the collision, and also on the chemical reactions they may have experienced as they orbited our solar system. Metallic asteroids are made of 80% iron, the rest are nickel compounds with some other metals mixed in, such as iridium, palladium, platinum, and gold. Some are also half made of silicate and metals.


Facts about asteroids 



1. Asteroids are very ancient celestial objects. The age of some asteroids known to us is comparable to the age of the solar system itself.


2. They appeared about 4.6 billion years ago and are remnants from the formation of our star system.


3. Asteroids consist mainly of stone, metals, various minerals, minerals and other substances. Moreover, some have a composition similar to the planetary one.


4. In 1801, the first asteroid Ceres was discovered by the Italian astronomer Giuseppe Piazzi. Although Ceres was called a planet until the 1860s. Then it was recognized as an asteroid body, and since 2006 it was given the status of a dwarf planet. In general, Ceres has a difficult fate, as we see.


5. When Ceres was reclassified as a dwarf planet, Vesta was considered the largest and most massive asteroid. The asteroid Vesta is so large and so bright that it can be seen from Earth with the naked eye.


6. There is a special place in the solar system where asteroids are located. This, of course, is the main belt or the Asteroid Belt. It is located between the orbits of Mars and Jupiter.



7. This is where most of all asteroids in the solar system are concentrated. It is here that there are stone blocks, of which there are over 300 thousand objects. Moreover, their total mass is about 4% of the mass of the moon.


8. It is believed that the name of the Asteroid Belt was given by Alexander von Humboldt in 1850. And then the term was officially approved.


9. Now asteroids, these unique celestial bodies, are being studied and researched by scientists all over the world.


10. But while we do not know all the secrets of the asteroid, much is still not known. For example, where do asteroids come from, and what will happen to them in the future. After all, the collisions that accompany their journey leave not only an imprint on the surface. They influence them, the nature of the movement. In the end, they lead to death and destruction. But that's the way the universe works.


11. There are many asteroids in the solar system, but some of them come to us from interstellar space.


12. Why are asteroids not destroyed when they collide? As it turned out, these stone-metal blocks are not completely destroyed upon impact. They crumble, and their fragments can fall to the surface or remain flying in outer space.



13. When they enter the atmosphere, they most often burn out. However, the largest of them can reach the surface layer, losing some of the substance.


14. Until 1807, asteroids were discovered: Pallas, Vesta and Juno. After that, astronomers decided that other such objects did not exist, and stopped searching.


15. And in 1845-47, Karl Ludwig Henke found Astrea and Hebe. In this connection, an active search and discovery of asteroids began.


16. Over time, astronomers found more and more similar bodies. In total, in less than a hundred years they discovered a thousand objects. As of 2011, about 285 thousand asteroids have official designations.


17. Some asteroids have satellites that are smaller asteroids.


18. Currently, about one and a half hundred asteroids with satellites have been discovered. The most famous such pair is the asteroid Ida and its satellite Dactyl.


19. The asteroid Chariklo has its own ring system, like the planet Saturn.



20. Asteroids are too small to have their own atmosphere. Their gravity is too weak to hold it.


21. Large asteroids have their own gravitational field, but it is very, very weak.


22. The moons of Mars, Phobos and Deimos, are likely to be asteroids once captured by the gravity of this planet. However, many other small satellites of the planets most likely appeared in the same way.


23. Asteroids never have the correct spherical shape - their mass is too small for this.


24. In most cases, asteroids are composed of rock, dust and ice. There are also metallic asteroids, but much less frequently.


25. On several asteroid bodies, not only ice was found, but also water.


26. Icy asteroids turn into comets, approaching the Sun - due to heating, they begin to evaporate, and a comet tail grows in them for a while.


27. It is also known that the chemical composition of asteroids changes with rotation and depending on the distance from the Sun.



28. In addition, they have different sizes, structures and shapes of orbits.


29. Most asteroids are not solid pieces of stone or metal, but mountains of debris, compressed under their own weight. They are divided into spectral classes.


30. In 2001, the first ever soft landing on an asteroid took place. Then the American probe Shoemaker landed on the asteroid (433) Eros.


31. Unmanned vehicles have repeatedly landed on asteroids, and the Japanese Hayabusa probe even brought back to Earth samples of the materials that make up the Itokawa asteroid.


32. Often asteroids collide with each other and with other objects, so there are craters on their surface. Interestingly, any celestial body has at least two recesses.


35. In practice, all asteroids are covered with the so-called regolith, that is, they are strewn with dust and loose formations that appear as a result of collisions and impacts.


34. Modern science believes that most of the asteroids in our system are the "remains of building materials" from which the Sun and the planets themselves were once formed.


35. Asteroids differ from dwarf planets primarily in that their mass is not large enough to acquire a spherical (or close to it) shape under the influence of their own gravity.



36. In the past, there was a theory that the main asteroid belt was formed from the debris of the planet Phaeton, located between Jupiter and Mars, but torn apart by their gravity. It was refuted, since the mass of the entire main belt is negligible compared to the mass of any planet, even a dwarf one.


37. The gas giant Jupiter plays the role of a protector for the Earth. Its powerful gravity attracts comets and asteroids that fly into the solar system, and they burn up in its atmosphere.


38. The word "asteroid" comes from the ancient Greek language, and it means "starlike". They were named so because after entering the atmosphere, when they burn up, they shine like small stars with tails.


39. In the future, industrial development of asteroids for the purpose of extracting minerals from them may well become economically viable.


40. There are, according to approximate estimates, several million asteroids in the main belt, but most of them have a diameter of no more than ten to twenty meters.


41. Now the former planet of the solar system Pluto is officially called "asteroid 134340". Although it refers to dwarf planets, they are designated as asteroids in the catalogs.


42. The Earth has not one satellite, but seven. In addition to the Moon, they include six more quasi-satellites, asteroids that are in orbital resonance with our planet.


43. About 700 asteroids orbit around the Earth, but they do not pose a danger, since the Earth's orbit does not intersect with them. And there are many thousands of them in the solar system.



44. But a special group of near-Earth objects has been identified that pose a potential danger to our planet. Therefore, they are closely monitored.


45. In 2004, the asteroid (99942) Apophis was discovered, which in 2029 and 2036 will pass in close proximity to the Earth.


46. ​​In the first case, a collision is excluded, and in the second case it is possible (because after the first transit the orbit of Apophis will change), but it is extremely unlikely. This is for the best, because the average diameter of Apophis is about 325 meters.


47. In the event of a collision with the Earth, the explosion will be more powerful than the one that accompanied the fall of the Tunguska meteorite, about 12 times, and this is according to the most conservative estimates.


48. On the asteroid Vesta is the crater Reyasilvia, in which the second highest mountain in the solar system is located. The diameter of the crater is about 500 km, which is almost equal to the diameter of Vesta itself, and the height of the peak from the base to the peak reaches 22 km. Only the ancient volcano Olympus on Mars (26 kilometers) is higher than it.


49. More than 100 thousand asteroids already have their own numbers, and some of them, with something interesting or remarkable, have their own names. The orbits of those that pose a potential threat are constantly monitored.



50. All asteroids from the asteroid belt of the solar system, if combined into a single sphere, will turn into a celestial body about 1500 kilometers in diameter, which does not even reach half the diameter of our moon.


51. Entering the atmosphere, the asteroid begins to be called a meteor. Most meteors burn out, but if they manage to reach the surface, they are called meteorites, and a crater forms at the site of their impact. The Gulf of Mexico is a giant crater - a consequence of the fall of a large asteroid.


52. Asteroids are not just stone and ice blocks flying somewhere far in space. This is also a practically unexplored area of ​​cosmology, and potentially a source of valuable minerals. But they can also carry a threat, because a collision with a fairly large asteroid can lead to a global cataclysm on Earth.


53. Danger for the very existence of life on Earth is a collision with asteroids, having from 10 kilometers in diameter. But much more compact space boulders can easily throw humanity back to the Stone Age.


54. According to one theory, it was a collision with a large asteroid that provoked the extinction of dinosaurs. A powerful enough impact could lift so much dust into the atmosphere that it would obscure the Sun for many years, and this would lead to an extremely sharp drop in temperature on our planet.


55. A service that tracks potentially dangerous asteroids has been created on earth for a long time. Interestingly, June 30th is International Asteroid Day.

Attempts to seize the territories of other planets cannot set states on fruitful interaction. This opinion was expressed on Tuesday by the Deputy Director General of Roscosmos for International Cooperation, Sergey Savelyev, commenting on a decree signed yesterday by US President Donald Trump in support of the commercial development of resources on the Moon by the United States.

 

"Attempts to expropriate outer space and aggressive plans to actually seize territories of other planets hardly set the countries to fruitful cooperation," Saveliev said.

 

He recalled that there were examples in history when one country decided to start seizing territories in its interests. “Everyone remembers what came of it,” Saveliev added.

 

On April 6, Trump signed a decree on the right of the United States to commercialize resources on the Moon and other celestial bodies. The document states that US citizens should have the right to conduct commercial research, to extract and use resources in outer space in accordance with applicable law.

 

 

In turn, the General Director of Roscosmos Dmitry Rogozin on his Twitter page stated that the two decrees signed by Trump “on the actual assignment of the moon and other celestial bodies to the United States” and on the state of emergency in the United States due to coronavirus can be related. “We are trying to understand how these decrees are interconnected,” he wrote.

 

At the same time, space is considered as a legally and physically unique space that the United States does not consider to be in the public domain. Thus, Washington does not recognize the agreement adopted by the UN General Assembly in 1979 on the activities of states on the moon and other celestial bodies, Gazeta.ru writes. The document states that the exploration and use of the satellite is the property of all mankind and is carried out in the interests of the world community, and the states involved in the exploration of the moon should cooperate and provide mutual assistance to each other.

 

Roscosmos, also known as the Roscosmos State Corporation for Space Activities, is the coordinating hub for space activities in Russia. It performs numerous civilian activities (including Earth monitoring and the astronaut program) and coordinates with the Defense Ministry of the Russian Federation for military launches.
