Discoveries and interesting facts about space, astronomy and astrophysics. Popular science articles about space. The best space photographs and only the facts.

Pluto is now not a planet to be precise, its scientists attributed it to dwarf planets, due to the fact that after clarifying the term what a planet is, Pluto turned out to be unable to clear its orbit from objects crossing it, it lacks mass. But this does not make Pluto a less interesting object in the solar system, let's continue our acquaintance with an entertaining dwarf.

The planet Uranus is the seventh from the Sun and the fourth in mass, belongs to the category of giants. If we compare the size of Uranus with other planets, then in this competition it will take an honorable third place. It is worth noting that scientists have identified due to the abundance of ice in various modifications on the planet, than Uranus is very similar to Neptune, both planets are in a sub-category, ice giants. What is mysterious about the ice giant, what interesting facts and features of its structure does it hide?

First, let's figure out what Enceladus is and what it is eaten with. First of all, this is the satellite of Saturn, the sixth largest, its feature that initially attracted scientists from all over the world, it is icy, its entire surface consists of water ice, but there is also a big one, but! The surface of Enceladus has an average temperature of -200 °C. At such a temperature, life is not possible, many will think, and this will be a mistake.

At the moment, a relatively little explored object of the solar system is a small dwarf planet Ceres, according to the catalog of the "Center for Minor Planets" 1 Ceres. The planet was discovered quite a long time ago in 1801 by the Italian Giuseppe Piazzi, its orbit is in the asteroid belt between Mars and Jupiter, by the way, this is the largest object in the belt.

On January 27, 1967, an international document was signed that formed the basis of space law and declared Space to be the property of all mankind. And for this day, we have prepared for you a selection of the most amazing facts about the Universe.

1. A day on the planet Venus lasts longer than a year. And all because this planet rotates around the Sun noticeably faster than around its own axis.

2. In space, it is much easier to hide emotions, because due to the lack of gravity, it is simply physically impossible to cry there.

3. There is no wind on the Moon, so any trace left there will last for centuries and even millennia.

4. The larger the planet, the stronger the force of gravity acts on it. So if on Earth a person weighs 60 kilograms, then on Jupiter (whose radius is more than 10 times the radius of the Earth), his weight would already be 142 kilograms.

5. The density of Saturn is almost half that of water. It turns out that if such a huge glass of water could be found, Saturn would float on its surface.

6. If you connect two metal parts in space, they will instantly weld to each other. On Earth, this is hindered by oxides that form on the surface of metals under the influence of our atmosphere.

7. Every year, the Moon moves away from the Earth by almost four centimeters.

8. Due to the absence of an atmosphere, all shadows on the moon are completely black.

9. Anyone who is sure that there is nothing of value in the outer space surrounding our planet should change their minds. In 2011, scientists discovered the planet PSR J1719-1438 b, almost entirely composed of diamond.

10. Lightning often occurs in space; scientists observe them on Mars and Saturn. In most cases, black holes are to blame for their appearance.

11. Everyone knows that shooting stars visible from the Earth are actually meteors burning up in the Earth's atmosphere. But the stars themselves can also move, just very, very rarely; this happens to only one heavenly body out of a hundred million.

12. The water found on Mars is heavier than Earth's: it contains five times more deuterium, an isotope of hydrogen with an extra neutron.

13. It has been proven that there is no magnetic field on the Moon. However, the stones brought by the astronauts from the satellite had magnetic properties.

14. If even a tiny amount of solar matter (for example, the size of a pinhead) hit the Earth, it would absorb oxygen at such an incredible rate that it would destroy all life within a radius of 160 kilometers in less than a second!

15. The largest volcano known to mankind is located on Mars. The giant named "Olympus" has a length of more than 600 kilometers, and its height is 27 kilometers. And this means that it is three times higher than the highest point on earth - Mount Everest.

16. Warming and giving us life, solar energy originated in the solar core as early as 30,000 years ago. She spent all these years trying to overcome the superdense shell of the heavenly body.

17. Venus is the only planet in the solar system that rotates counterclockwise.

18. The official scientific theory claims that a person is able to survive in open space without a spacesuit for as much as ninety seconds, but only if all the air is immediately exhaled from the lungs.

19. Scientists from Harvard University have proven that some of the earth's rocks are of Martian origin. True, a very small part: only 0.67 percent.

20. Earth's gravity makes us lower: in outer space, the human spine "unclenches" by more than five centimeters.

Incredible Facts

Sometimes it's hard to imagine how big is space.

We can observe only a small part of the Universe, and the Earth is just a small scene in a vast outer space.

Here are some interesting facts about space that might make you think about your place in this world.

1. The sun makes up 99.8 percent of the mass of the solar system.

Namely 1,989,100,000,000,000,000,000,000,000,000 kg. All other planets, satellites, asteroids and other matter, including all people on Earth fit into the remaining 0.2 percent.

2. A gas cloud in the constellation Eagle contains enough alcohol to create 200 septillion liters of beer.

The amount of ethanol was measured in 1995 and scientists found 30 other chemicals in the cloud, but alcohol was the main one.

3. We have discovered more than a thousand planets outside the solar system in the last 20 years.

So far, 1822 planets have been confirmed to exist.

4. The sound of interstellar space sounds creepy

The Voyager 1 spacecraft recorded the sound of vibrating dense plasma in interstellar space in 2012 and 2013. Here's how it sounds.

Planets of the solar system

5. All the planets in the solar system could fit between the Earth and the Moon.

Distance between the Earth and the Moon (384,440 km) - [Diameter of Mercury (4879 km) + diameter of Venus (12,104 km) + diameter of Mars (6771 km) + diameter of Jupiter (138,350 km) + diameter of Saturn (114,630 km) + diameter of Uranus (50,532 km) + diameter of Neptune (49,105 km)] = 8069 km

6. It takes a photon an average of 170,000 years to travel from the Sun's core to the surface.

But only 8 minutes to reach Earth.

7. We won't be able to hear any sounds in space.

Voyager attempted to record the sound of interstellar space with the plasma wave instrument, but since the gas in interstellar space is less dense, we cannot hear the sound ourselves.

If a sound wave traveled through a large cloud of gas in space, only a few atoms per second would reach the eardrum, and we would did not hear the sound, because our eardrum is not sensitive enough.

8. The rings of Saturn disappear from time to time.

Every 14-15 years, the rings of Saturn turn edge-on towards the Earth. They are so narrow compared to how big Saturn is that they seem to disappear.

9. Saturn has an additional huge ring, discovered only in 2009.

The ring begins about 6 million kilometers from Saturn, and its length is 12 million km, which would fit 300 Saturns. Saturn's moon Phoebe rotates inside the ring, and some astronomers believe that it is he who is the source of the ring.

10. There is a hexagonal cloud at the north pole of Saturn.

The hexagonal vortex extends nearly 30,000 km across.

11. In our solar system there is an asteroid with rings, like Saturn.

The asteroid Chariklo has two dense and narrow rings. it fifth object in the solar system that has rings, along with Saturn, Jupiter, Neptune and Uranus.

12. Jupiter is 2.5 times more massive (heavier) than all the planets in the solar system combined.

Its weight is equal to the weight of 317.8 planets like the Earth.

13. More solar energy hits the Earth in an hour and a half than we used in all of 2001.

14. If you fell into a black hole, you would be stretched like noodles.

The phenomenon is called spaggification.

15. If nothing disturbs the Moon (for example, a meteorite), then the traces left on its surface will remain intact forever.

Unlike Earth, there is no erosion caused by wind and water.

16. A star has recently been discovered that has been hiding in the brilliance of a supernova for 21 years.

The star and its companion, which exploded and hid it from view, are in the galaxy M81, located at a distance of 11 million light-years from Earth.

17. Dung beetles navigate the Milky Way.

Birds, seals, and humans use the stars for orientation, but African dung beetles use the entire galaxy, not individual stars, to make sure they are moving in a straight line.

18. An object the size of Mars collided with Earth 4.5 billion years ago.

This is by far the most plausible explanation of how the moon formed. A chunk broke off from the object, which became the Moon, and caused the Earth's axis to tilt slightly.

Stars of the universe

19. We are all made of stardust.

After the Big Bang, tiny particles coalesced into hydrogen and helium. Then, in the very dense and hot centers of the stars, they combined to create the elements, including iron.

Since humans and other animals and most of matter contain these elements, we can be said to be composed of stardust.

20. There are countless stars in the known universe.

We don't know how many stars there are in the universe. For now, we're using ballpark estimates to find out how many stars there are in our Milky Way galaxy. Multiplying this number by the estimated number of galaxies in the universe, we can say that there is an unimaginable number of stars.

According to a study by the Australian National Institute, the number of stars is approximately 70 sextillion, which is 70,000 million million million.

Even primitive people riveted their views on the night sky, trying to find out what kind of luminous points are on it. Some thought that gods lived in heaven, others believed that creatures unknown to man lived in heaven, and even to this day, a person has not developed a complete understanding of what the cosmos really is.

As a rule, interesting facts about space are always in the spotlight, attracting many readers around the world. The mysteries and mysteries of the Universe do not leave indifferent almost any of us. Are there extraterrestrial civilizations? How long does it take to get to the nearest galaxy? Why do stars sparkle in different colors?

Agree, everyone wants to know the answers to such questions, regardless of gender, age, social status. This section of our portal contains interesting scientific articles about space that will expand your imagination, immerse you in the world of the mysterious, mysterious, unimaginable.

Scientific articles about space fromKwant.Space

Modern science, which was formed in the 20th century, developed very dynamically, presenting new incredible discoveries, starting with the invention of the conventional battery and ending with the landing of a man on the moon. However, all this was only the beginning, only a drop in the ocean of knowledge that awaits humanity ahead. As for space exploration, it has become even more rapid in the 21st century. The invention of super-powerful telescopes has given man the opportunity to see other galaxies with stars and planetary systems. The curtain of mystery about the origin of the Universe was opened by mathematicians, physicists, astronomers and other scientists of our time.

The mysteries of the universe, the big bang theory, the existence of extraterrestrial intelligence - all this is of interest not only to specialists exploring outer space. This information will be of interest to everyone, so the portal site provides you with scientific articles about space, including theories of the origin of matter, descriptions of cosmic bodies, estimates of distances in outer space, and much more. People wrongly think that scientific articles are written by scientists for their colleagues. They contain information that expands our worldview. Scientific articles about space are never boring, because this is a very broad topic, including a lot of interesting points.

Why do lovers like to sit under the starry sky at night? The answer is simple - the night sky is incomparable to any decor. You don't have to go far in pursuit of romance. Look at the sky at night. The stars that are scattered on it with luminous peas are so different from each other. Multi-colored twinkling of stars, fascinating bright traces from the fall of meteorites - can anything be more romantic? It would be great to know more about all this. Unfortunately, our imagination is not capable of unraveling all the mysteries of the cosmos, even the brightest “minds” of the world cannot do this. But science does not stand still. Every day new discoveries of space objects are made, various hypotheses and theories are confirmed and refuted. Scientific articles about space published on the site are written on the basis of the works of famous scientists who have completely devoted themselves to unraveling the mysteries of the Universe.

The launch of the Hubble Space Telescope into Earth orbit in 1990 helped astronomers see galaxies billions of light-years from Earth. The pictures taken by this most powerful modern telescope not only make it possible to see space objects, but also to analyze the development of the Universe.

How scientific articles about space are created

Numerous news from distant worlds provide us with the most valuable information about the Universe. However, all this would be only a set of facts if a person could not analyze them, compare them with each other, find certain connections and patterns, be able to think, reflect and draw conclusions. It was the human mind that helped create wonderful tools and devices that capture and decipher information from space. But not all phenomena from the surrounding world can be observed. Moreover, not every event in space that we observe comes from another that we already know. Thus, scientific theory comes to the aid of scientists. Thanks to its application, it becomes possible to reveal the relationship between various processes and phenomena, to restore the missing links, to predict new facts, to study such problems that cannot be solved by observations or measurements alone. It is the use of theory that points the way for further research, poses primary tasks for scientists, concentrating their efforts in certain areas, and aims at establishing certain facts.

The existence of a theory without observational data and facts is impossible. Without them, it would be just empty logical exercises, solutions to speculative problems that do not contain any valuable information about the world around. It would be a mere kaleidoscope without a theoretical basis and without elucidation of the laws governing the facts, which would be of little use to the researchers of the Universe. Observations together with theoretical research are two twin brothers who cannot live alone in modern science without a second.

By their nature, theoretical studies in modern astronomy are very diverse. Here there are both statistical calculations, and mathematical calculations, and bold guesses along with original hypotheses.

On our portal site you can find a variety of scientific articles about space. You will learn the hypotheses of the origin of matter, meet the description of planets, galaxies, stars, nebulae and comets, get acquainted with the works of the world's leading astrophysicists and mathematicians who explore outer space.

Basically, a scientific article is written on the basis of observations. When it comes to observing cosmic bodies, it is worth understanding that capturing cosmic light rays coming from space is only half the battle. These beams still need to be fixed. For many years, astronomers did this in a very primitive way: they looked through the eyepiece of a telescope, and then simply redrawn what they saw and recorded the results of their observations.

However, human eyes tend to succumb to fatigue. Several hours of continuous observation significantly dull visual acuity and reduce the accuracy of perception. Therefore, astronomers, when conducting research, instead of tedious visual observations, use the photographic method. Modern cameras make it possible to automate the process of space exploration. Scientific articles about space, which you can find in this section of our portal, are supported by real photographs of space objects.

Recent science has indeed brought us many brilliant discoveries.

In just a few decades, we have invented powerful computers and now we can work with gigantic amounts of information.

Thanks to the invention of super-powerful engines, man was able to overcome the force of gravity and escape into outer space. In 1961, a person could see with his own eyes that the Earth is really a ball. And before that, everything was only at the level of assumptions, hypotheses and theories. Scientists are racking their brains to find evidence for their theories. There are still so many unexplained things in space! New patterns are being discovered, new bodies are being given their names. Further, they become the subject of discussions at meetings of scientists and scientific conferences. In general, the topic "space" is difficult to understand. After all, we have to talk about those objects that are at a great distance. If man was still able to get to the Moon and collect samples of its surface, then other celestial bodies are still inaccessible. Therefore, their description will be based only on the materials obtained by the telescope. Scientific articles about space are useful for people of any age. They are interesting to read to children who are able to instantly absorb large amounts of information. They will also be of interest to adults, regardless of their profession. After reading such a text, there is always something to think about.

How many people - so many opinions. When you read a hypothesis, you can either agree with it or not. Mostly in articles on the subject of space there is no reliable data. Conclusions are based only on the reasoning of scientists involved in the study of a particular phenomenon. It is not easy to describe what cannot be seen at close range, cannot be felt and considered from all sides. This is the complexity of the work of astrophysicists. Using images alone, they must conclude about the distance to the cosmic body, its temperature, physical condition and many other factors. Space is that scientific topic that has no beginning and no end. Indeed, in the Universe there are many galaxies, stars, planets and nebulae, each of which is the subject of new scientific research. The only question is how quickly a person will be able to access technologies that help to reach these objects at a short distance. The plots of science fiction films tell how people in a few hundred years will travel from planet to planet. It cannot be said that all these are inventions of the pen, because over the past century science has made a leap forward, covering almost all areas of our life. One way or another, the issue of space colonization, although not an urgent need, is raised not only by science fiction writers, but also by scientists. Some of them put forward bold theories that a person can colonize Mars, others are looking for a planet in neighboring galaxies with an atmosphere similar to Earth, which may be suitable for life.

It cannot be argued that the cosmos is something far from us, something that does not affect us in any way. Solar flares cause magnetic storms on Earth, which affects the deterioration of human well-being. In the same period, the probability of failure of household appliances increases.

Humanity should be interested in the subject of outer space, because it is from there that the greatest risk of the death of civilization comes. At the scientific level, little is said about this, although some theories say that the dinosaurs died precisely as a result of the collision of the Earth and a large cosmic body. "Messengers of the Universe", which sometimes enter the atmospheric space of our planet, are fraught with a hidden threat. Since this problem concerns all the inhabitants of the Earth, states should make every effort to pursue a peaceful policy of space exploration with elements of the commonwealth.

Man has achieved significant results in space exploration. However, much remains undiscovered and unconfirmed. Space exploration will never lose its relevance, because it makes it possible to determine according to what laws the Universe developed, where did life on Earth come from, and can it be anywhere else? Our site site offers a collection of scientific articles about space, in which well-known "minds" of our time express their reasoning on issues in this area. Perhaps in the near future we will get a clear and precise answer to what the Universe and the cosmos are, where it all came from. At the present time, the Big Bang Theory is very popular, which explains the principle of the origin of matter in the Universe. Scientists are finding more and more evidence for this theory, reinforcing reasoning with laboratory experiments.

Every day humanity is interested in space more and more. We are aware that we are strongly dependent on the ongoing processes in the Universe. We want to understand how the universe works, although this is hardly possible. We will wait for new interesting discoveries that can make our life easier, better and more comfortable.

What do we know about space? Most of us cannot answer the simplest questions about this mysterious world, which, despite this, attracts and interests us. This article presents the most interesting general information about space, which will be useful for everyone to know.

• We (all living beings) are flying in the space environment at a certain speed, which is equal to 530 km/sec. If we take into account the speed of movement of our Earth in the galaxy, then it equates to 225 km / second. Our galaxy (the Milky Way), in turn, moves in space at a speed of 305 km/sec.

• A giant space object - the planet Saturn actually has a relatively small weight. The density of this giant planet is a couple of times lower than that of water. Thus, if you try to drown this cosmic body in water, this will not work.
• If the Jupiter planet were hollow, then all the known planets of our solar planetary system could fit inside it.
• Reducing the periodicity of the rotation of the planet-Earth will move the Moon away from it by about four centimeters annually.
• The first "star catalog" was compiled by Hipparchus (astronomer) in 150 BC.

• When we look at the most distant (dimmest) stars in the night sky, we see them as they were about fourteen billion years ago.
• In addition to our luminary, we have another approximate star "Proskima Centauri". The distance to this space object is equal to 4.2 light years.
• The "red giant" named "Betelgeuse" has a huge diameter. For comparison, its diameter is a couple of times greater than the orbit of our Earth around the star.
• Every year, the galaxy in which our planetary system is located produces about 40 new stars.
• If one spoon (tea) of substance is removed from the "neutron star", then the weight of this spoon will be equal to 150 tons.

• The mass of our luminary is more than 99% of the mass of its entire planetary system.
• The age of the light emitted by our luminary can be equated to only 30 thousand years. It was thirty thousand years ago that a certain energy was formed in the luminary, which to this day reaches the Earth. By the way, solar photons get to the aforementioned planet on which we live, in just eight seconds.
• The eclipse of our star can last no more than seven and a half minutes. The lunar eclipse, in turn, has a longer duration - 104 minutes.
• The "solar wind" is the cause of the mass loss of our luminary. In 1 second, this luminary loses more than 1 billion kg due to this “wind”. By the way, one "windy particle" can destroy an ordinary person, approaching him at a distance of 160 kilometers.
• If our Earth were spinning in a different, opposite direction, then the duration of the year would be less by a couple of days.
• Every day, our planet is experiencing a “meteorite bombardment”. Why don't we see this? Most of the space objects falling on us are very small, so they do not have time to reach the surface and dissolve in our atmosphere.

• Our planet has far more than one satellite. Modern scientists have determined that four objects fly around it at once. Of course, the most famous of them is the Moon. In addition to it, an asteroid (5 kilometers in diameter) flies around us, which was discovered in 1896. To be more precise, this object revolves around the star, but with a certain frequency, the same as ours. Therefore, he is always with us. It is impossible to see it with the naked eye.
• The condensation of "cosmic matter" is the cause of the periodic increase in the mass of our planet. Every 500 years, its mass increases by about one billion tons.
• The Big Dipper is not a constellation, as many people think. In reality, this is "asterism" - a visual cluster of stars that are very impressively distant from each other. Some Ursa stars are even located in different galactic formations.

Initially, the planet Uranus, discovered by W. Herschel in 1781, was called the "Star of George." This was ordered by George III, who wanted the last discovered planet of the Solar System to be named after him.

If two parts of a meteorite come into contact in outer space, they will be soldered together. If this happens on our native planet, then they will not unite, since metals tend to oxidize on our planet. The equipment that astronauts use while working outside the space station spontaneously oxidizes on Earth, so it does not stick together in outer space.

Satellite vehicles created by engineers during their flight in space obey certain physical laws, which were first described by Newton.

Since 1980, sections of our satellite, the Moon, have been officially sold, and they cost a lot. To date, about seven percent of the surface of the natural satellite has been sold. The cost of forty acres is now no more than $150. The lucky person who bought the plot receives a certificate and photographs of his "lunar land".

• In 1992, the official couple Jen and Mark went into space. To this day, they are considered the first and only spouses who visited space together. The couple flew into space on the ship "Endever".
• All those who have been in space for a certain time (1-2 months) grow by about five centimeters due to spinal sprain, which then, after returning to Earth, can adversely affect health.
• A satellite orbital system can photograph three million square kilometers of the Earth in half an hour, an airplane in twelve years, a person by hand in approximately 100 years.
• In 2001, they conducted an interesting experiment, after which they found out that astronauts snoring at home in outer space lose this bad habit.
