The temperature in space, in Earth's orbit is +4°C

To be precise, it is not in the orbit of the Earth, but at a distance from the Sun equal to the distance of the Earth's orbit. And for a completely black body, i.e. one that completely absorbs the sun's rays without reflecting anything back.

It is believed that the temperature in space tends to absolute zero. Firstly, this is not entirely true, since the entire known Universe is heated up to 3 K, by cosmic microwave background radiation. Secondly, the temperature rises near the stars. And we live pretty close to the sun. Strong thermal protection is needed for space suits and spaceships because they enter the Earth's shadow, and our luminary can no longer warm them up to the indicated + 4 ° C. In the shade, the temperature can drop to -160 ° C, for example at night on the moon. It's cold, but it's still far from absolute zero.

Here, for example, the readings of the onboard thermometer of the TechEdSat satellite, which rotated in low Earth orbit:

It was also affected by the earth's atmosphere, but in general, the graph does not show the terrible conditions that are usually represented in space.

Lead snow falls in places on Venus

This is probably the most amazing fact about space that I have learned not so long ago. Conditions on Venus are so different from anything we could imagine that Venusians could easily fly to hell on earth to rest in a mild climate and comfortable conditions. Therefore, no matter how fantastic the phrase "lead snow" may seem, for Venus it is a reality.

Thanks to the radar of the American probe Magellan in the early 90s, scientists discovered a certain coating on the tops of the Venusian mountains that has a high reflectivity in the radio range. Initially, several versions were assumed: the consequence of erosion, the deposition of iron-containing materials, etc. Later, after several experiments on Earth, they came to the conclusion that this is the most natural metallic snow, consisting of bismuth and lead sulfides. In a gaseous state, they are released into the planet's atmosphere during volcanic eruptions. The thermodynamic conditions at 2600 m then favor compound condensation and precipitation at higher elevations.

There are 13 planets in the solar system...or more.

When Pluto was demoted from the planets, it became a rule of good manners to know that there were only eight planets in the solar system. True, at the same time, they introduced a new category of celestial bodies - dwarf planets. These are "underplanets", which have a rounded (or close to it) shape, are not anyone's satellites, but at the same time they cannot clear their own orbit from less massive competitors. Today it is believed that there are five such planets: Ceres, Pluto, Hanumea, Eris and Makemake. The closest to us is Ceres. In a year, we will learn much more about her than now, thanks to the Dawn probe. So far, we only know that it is covered with ice and water evaporates from two points on its surface at a rate of 6 liters per second. We will also learn about Pluto next year, thanks to the New Horizons station. In general, just as 2014 will be the year of comets in astronautics, 2015 promises to be the year of dwarf planets.

The remaining dwarf planets are located beyond Pluto, and we will not know any details about them soon. Just the other day, another candidate was found, though officially it was not included in the list of dwarf planets, just like its neighbor Sedna. But it is possible that they will find more, several larger dwarfs, so the number of planets in the solar system will still grow.

The Hubble telescope is not the most powerful.

Thanks to the huge amount of images and impressive discoveries made by the Hubble telescope, many have the idea that this telescope has the highest resolution and is able to see details that cannot be seen from Earth. For a while, this was true: despite the fact that large mirrors can be assembled on Earth on telescopes, the atmosphere introduces a significant distortion in the images. Therefore, even a "modest" by earthly standards mirror with a diameter of 2.4 meters in space, allows you to achieve impressive results.

However, over the years that have passed since the launch of Hubble and terrestrial astronomy has not stood still, several technologies have been developed that allow, if not completely getting rid of the distorting effect of air, then significantly reducing its impact. Today, the European Southern Observatory's Very Large Telescope in Chile can provide the most impressive resolution. In the optical interferometer mode, when four main and four auxiliary telescopes work together, it is possible to achieve a resolution that exceeds that of Hubble by about fifty times.

For example, if Hubble gives a resolution on the Moon of about 100 meters per pixel (hello to everyone who thinks that this is how you can see the Apollo landers), then VLT can distinguish details up to 2 meters. Those. in its resolution, American landers or our lunar rovers would look like 1-2 pixels (but they will not look because of the extremely high cost of working time).

A pair of telescopes at the Keck Observatory, in interferometer mode, are capable of ten times the resolution of Hubble. Even individually, each of Keck's 10-meter telescopes, using adaptive optics technology, is able to outperform Hubble by a factor of two. For example, a photo of Uranus:

However, Hubble does not remain without work, the sky is large, and the breadth of the space telescope's camera exceeds ground capabilities.

Bears in Russia are 19 times more common than asteroids in the main asteroid belt.

An American popular science site cites, and the Computer translates, curious calculations that show that travel in the asteroid belt is not as dangerous as George Lucas imagined. If all asteroids larger than 1 meter are placed on a plane equal to the area of ​​the main asteroid belt, then it turns out that one stone falls on about 3200 square kilometers. Russia's 100,000 bears are to be distributed one by one for every 170 square kilometers of territory. Of course, both asteroids and bears try to stay close to their own kind and defile pure mathematics with their uneven distribution, but for the sake of a holiday, such trifles can be neglected.

The report on the topic "Space" will briefly tell you a lot of useful information about the Universe and how it was explored. Also, a message about space will help prepare for an astronomy class.

Space message

What is space?

From the Greek language, the concept of "cosmos" means a device, order, harmony. Even in Ancient Greece, philosophers considered the Universe as a harmonious ordered system, which was compared to chaos and disorder.

Cosmos means something unified, which obeys general laws and is outside the Earth's atmosphere. Man more or less carefully explored the near-Earth space of space: rockets have been here and even the routes of artificial satellites of the planet have been laid. From the moment of flights of spaceships on board with crews and the free exit of astronauts into outer space, the field of study of the Universe has expanded.

Universe today

Modern astronomers believe that matter and space arose in the course of a powerful explosion of something dense and hot. The explosion occurred 10-20 billion years ago. Since then, the universe has been continuously cooling and expanding. In the first seconds after the big bang, electrons and quarks turned into molecules and atoms, oxygen appeared.

Since the expansion of the Universe continues, scientists are considering various scenarios for its development in the future. So, the first scenario says that it can shrink to a point. This unstable state will lead to an irreversible process - the Universe will disappear irreversibly and in one instant. If it continues to expand, then the temperatures will balance and become the same at all points in space. The stars will move away from each other, cool down and stop emitting light. Black holes will "evaporate" and disappear. There is also another scenario - the force of mutual attraction will stop the expansion process and the galaxies will begin to fall on each other.

How many stars and planets are there in space?

The scale of the universe is simply enormous. Therefore, the number of planets, stars in it is also large. Since the big bang, the number of "cosmic population" has been constantly growing. Astronomers have counted many galaxies, each containing more than 100 billion stars. In 1996, 50 billion galaxies were known. Today their number has reached 125 billion. But there are 12500000000000000000000 stars in them. This is an incredible number. But, of course, this figure is not final, it is impossible to calculate the exact number of stars. But you can determine the brightest star - Sirius, which shines more intensely than the Sun.

As a rule, groups of planets that form with a star move around the stars - solar systems. The most familiar to us is the solar system of the Earth. In its center is the Sun, a star around which 9 planets revolve, more than 63 satellites, 4 ring systems, meteoroids, asteroids, comets. Between them, protons and electrons, particles of the solar wind, move in space.

The sun emits light that is reflected by the planets around it. Their location from the main star is as follows: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. Each of them is unique and special.

Space exploration - who was the first?

The path to space was opened during the Cold War between the US and the USSR. The first country to open the way to space was the USSR. She first launched the artificial satellite Sputnik 1 in 1957 into Earth's orbit. In response, the United States also launched the artificial satellite Explorer 1 on February 1, 1958.

The satellites were sent for scientific purposes: to calculate the density of the upper atmosphere and search for the Earth's radiation belts. In the course of the race, the two superpowers did not stop there. The USSR sent a man into space in 1961, and before that, animals had been there. Today, the United States has the greatest success in the field of space exploration.

We hope that the report on space helped you prepare for the lesson. A report about space, you can add through the comment form below.

Space, perhaps, is currently one of the biggest mysteries for all mankind. People do not get tired of exploring the cosmos, discussing it, putting forward a wide variety of theories, building a wide variety of assumptions, but still the cosmos remains something incredible, mysterious, unidentified to the end. And does it have an end that can be reached, guided by science? Most probably not. Probably, the cosmos throughout the entire existence of mankind will, to one degree or another, remain a mystery, an unsolvable mystery, like a huge Sphinx, the question of which cannot be answered. But still they study it, and therefore we know a lot about space, which amaze and sometimes frighten. Let's take a closer look at some interesting facts about space and the universe.

1. About forty new stars are born in our galaxy every year. How many of them appear in the entire universe - it is difficult to even imagine the answer to this question.
2. Silence reigns in space, since there is no medium for sound to propagate. So for those who like to be silent, space would certainly be to their liking.
3. For the first time, man looked at space through a telescope about four centuries ago. It was, of course, Galileo Galilei.
4. Surprisingly, in space, all the flowers we know will smell completely different. And all because the smell of a flower depends on many different environmental factors.
5. An interesting fact about space and planets is that the sun is about one hundred and ten times larger than the earth. It is even larger than Jupiter, which is known to be the giant of our solar system. But at the same time, if we compare the Sun with other stars in the Universe, then it will turn out to be incredibly tiny. For example, the star Canis Major is one and a half thousand times larger than the Sun.
6. The first terrestrial creature in space is the dog Laika, which was launched into outer space on Sputnik 2 in 1957. The dog died on the ship due to lack of air. And the satellite itself burned up in the Earth's atmosphere due to a violation of its orbit.
7. The first man in space is Yuri Gagarin. With a slight delay after Gagarin, Alan Shepard, an American cosmonaut, flew into space.
8. The first woman in space is Valentina Tereshkova.
9. Most of the atoms that make up human bodies were formed during the melting of stellar mass.
10. On Earth, due to the presence of gravity, the flame tends to rise in an upward direction, but in space it spreads in all directions.
11. A person will never be able to reach the edge of the universe, since there is a curvature of space in space, because of which a person, moving constantly in a straight direction, will eventually return to the starting point. Scientists are not yet able to explain this to the end.
12. On average, the distance between stars is thirty-two million million kilometers.
13. An interesting fact about black holes in space is that they are the brightest objects in the universe. In general, gravity inside a black hole is so strong that even light cannot escape from it. But during its rotation, the black hole absorbs not only a variety of cosmic bodies, but also gas clouds, which begin to shine, spinning in a spiral. Meteors also start to burn when falling into a black hole.
14. Approximately ten tons of cosmic dust falls on Earth every day.
15. There are more than one hundred billion galaxies in the Universe, so there is a huge possibility that people are not alone within the boundaries of this Universe.

The most interesting facts about the cosmos can be collected and written down for an incredibly long time, since our Universe contains a huge number of secrets and mysteries, to which we can now, thanks to the development of science, come at least a few steps closer.

Space- the most discussed and, at the same time, the most mysterious topic on the entire planet Earth. On the one hand, humanity has learned a lot about it, on the other hand, we know a tiny percentage of what is actually happening in the Universe. Today we will look at some of the most interesting facts about space.

It turns out that our satellite - the Moon - is moving away from us every year by about 4 cm. This depends on the decrease in the period of rotation of the planet by 2 miles of a second per day.

Forty new stars are born every year in our galaxy alone. It is difficult to even imagine how many of them appear in the entire universe.

The universe has no boundaries. It seems that everyone is familiar with this statement. In fact, no one knows if the cosmos is infinite or just gigantic.

All the stars, galaxies and black holes in the universe make up only 5% of its mass. It's amazing, but 95% of the mass is incalculable. Scientists decided to call this mysterious substance "dark matter" and to this day no one can accurately determine its nature.

Our solar system is terribly boring. If you think about our neighbors, they are all unremarkable gas balls and pieces of stone. Multiple voids of light separate us from the nearest star. In the meantime, other systems are full of amazing stuff.

In the vastness of the Universe there is a very amazing thing - giant gas bubble. Its length is about 200 million light years, and it is located 12 billion of these years from us! This interesting thing formed just two billion years after the Big Bang.

The Sun is about 110 times larger than the Earth. It is even larger than the giant of our system - Jupiter. However, if we compare it with other stars in the Universe, our luminary will take a place in the nursery of a kindergarten, that's how small it is.
Now let's imagine a star that is 1500 times larger than our Sun. Even if we take the entire solar system, it will not take up more than a pixel of this star. This giant is called VY Big Dog, whose diameter is about 3 billion km. How and why this star was blown to such dimensions, no one knows.

Science fiction writers have fantasized about five different types of planets. It turns out that there are hundreds of times more of these species. Scientists have already discovered about 700 types of planets. One of them is a diamond planet, and in every sense of the word. As you know, carbon needs very little to turn into a diamond in this case, the conditions coincided so that one of the planets solidified and turned into a gem of a universal scale.

A black hole is the brightest object in the entire universe.

Inside a black hole, the force of gravity is so strong that even light cannot escape from it. Logically, the hole should not be visible in the sky at all. However, during the rotation of the hole, in addition to cosmic bodies, they also absorb gas clouds, which begin to glow, twisting in a spiral. Also, meteors, falling into black holes, light up from an incredibly sharp and fast movement.

The light of our sun, which we see every day, is about 30 thousand years old. The energy we receive from this celestial body was formed in the core of the Sun about 30 thousand years ago. That's how much time and no less is necessary for photons to break through from the center to the surface. But after the "liberation" they need only 8 minutes to get to the surface of the Earth.

We fly in outer space at a speed of about 530 km per second. Inside the Galaxy, the planet moves at a speed of about 230 km per second, the Milky Way itself flies through space at a speed of 300 km per second.

About 10 tons of cosmic dust “falls” on our heads every day.

There are over 100 billion galaxies in the entire universe. There is a chance we are not alone.

Interesting fact: Every day, about 200 thousand meteorites fall on our planet!

The average density of Saturn's substances is half that of water. This means that if you lower this planet into a glass of water, it will float on the surface. You can check this, only, of course, if you find the appropriate glass.

The sun is "losing weight" by a billion kilograms per second. This is due to the solar wind - a stream of particles that move from the surface of this star in different directions.

If we wanted to get by car to the nearest star after the Sun - Proxima Centauri, then we, at a speed of 96 km / h, would need about 50 million years.

Earthquakes even happen on the moon, which are referred to as moonquakes. But, nevertheless, in comparison with the earthly ones, they are insignificantly weak. There are more than 3,000 such moonquakes every year, but this total energy would only be enough for a small salute.

The strongest magnet in the entire universe is the neutron star. Its magnetic field is millions of billions of times greater than the field of our planet.

It turns out that in our solar system there is a body that resembles our planet. It is called Titan, and it is a satellite of the planet Saturn. It also has rivers, seas, volcanoes, a dense atmosphere, just like our planet. Surprisingly, even the distance between Titan and Saturn is equal to the distance between us and the Sun, and even the ratio of the weight of these heavenly bodies is equal to the ratio of the weight of the Earth and the Sun.
Yet intelligent life on Titan is not even worth looking for, because its reservoirs failed: they consist mainly of propane and methane. But still, if the latest discovery is confirmed, then it will be possible to argue that primitive life forms exist on Titan. Under the surface of Titan there is an ocean, which consists of 90% water, the remaining 10% can be complex hydrocarbons. There is an assumption that it is these 10% that can give rise to the simplest bacteria.

If the Earth revolved around the Sun in the opposite direction, then the year would be two days shorter.

The duration of a total lunar eclipse is 104 minutes, while the duration of a total solar eclipse is only 7.5 minutes.

Isaac Newton was the first to state the physical laws that artificial satellites obey. They were first published in the work "Mathematical Principles of Natural Philosophy" in the summer of 1687.

The funniest fact! Americans have spent more than one million dollars to invent a pen that would write in space. The Russians, on the other hand, used a pencil in zero gravity without making any changes to it.

In the orbit of our planet there is a dump of waste from the development of astronautics. More than 370,000 objects weighing from a few grams to 15 tons revolve around the Earth at a speed of 9,834 m / s, colliding with each other and scattering into thousands of smaller parts.

The main contender for the title of habitable planet in the extrasolar system, "Super-Earth" GJ 667Cc, is only 22 light-years away from Earth. However, the journey to it will take us 13,878,738,000 years.

Our closest galaxy, Andromeda, is located at a distance of 2.52 million years. The Milky Way and Andromeda are moving towards each other at tremendous speeds (Andromeda's speed is 300 km/s, and the Milky Way is 552 km/s) and will most likely collide in 2.5-3 billion years.

"Cosmic whirligig" called a neutron star- This is the fastest spinning object in the Universe, which makes up to 500 revolutions per second around its axis. In addition, these cosmic bodies are so dense that one tablespoon of their constituent matter will weigh ~10 billion tons.

In space, tightly compressed metal parts spontaneously weld together. This occurs as a result of the absence of oxides on their surfaces, the enrichment of which occurs only in an oxygen-containing environment (the earth's atmosphere can serve as a good example of such an environment). For this reason, NASA (National Aeronautics and Space Administration) specialists treat all metal parts of spacecraft with oxidizing materials.

Earth gravity compresses the human spine, so when an astronaut enters space, he grows about 5.08 cm. At the same time, his heart contracts, decreasing in volume, and begins to pump less blood. This is the body's response to an increase in blood volume that requires less pressure to circulate normally.

The weight of our planet- This is an inconstant value. Scientists have found that every year the Earth recovers by ~40,160 tons and dumps ~96,600 tons, thus losing 56,440 tons.

The official scientific theory says that a person can survive in outer space without a spacesuit for 90 seconds., if you immediately exhale all the air from the lungs. If a small amount of gases remains in the lungs, they will begin to expand with the subsequent formation of air bubbles, which, if released into the blood, will lead to embolism and inevitable death. If the lungs are filled with gases, then they will simply burst. After 10-15 seconds of being in outer space, the water in the human body will turn into steam, and the moisture in the mouth and before the eyes will begin to boil. As a result of this, soft tissues and muscles will swell, which will lead to complete immobilization. This will be followed by loss of vision, glaciation of the nasal cavity and larynx, blue skin, which in addition will suffer from severe sunburn. The most interesting thing is that the next 90 seconds the brain will still live and the heart will beat. In theory, if during the first 90 seconds an unsuccessful cosmonaut who has been tormented in outer space is placed in a pressure chamber, then he will get off with only superficial injuries and a slight fright.

The largest meteorite that fell to Earth is considered to be 2.7 meter "Goba" (Hoba) found in Namibia. The meteorite weighs 60 tons and is 86% iron, making it the largest piece of naturally occurring iron on Earth.

Venus is the only planet in the solar system, which rotates counterclockwise. There are several theoretical justifications for this. Some astronomers are sure that such a fate befalls all planets with a dense atmosphere, which first slows down and then spins the celestial body in the opposite direction from the initial rotation, while others suggest that a group of large asteroids fell on the surface of Venus.

Contrary to popular belief, the cosmos is not a complete vacuum, but it is close enough to it, because. There is at least 1 atom per 88 gallons (0.4 m3) of cosmic matter (and as is often taught in school, there are no atoms or molecules in a vacuum).

The density of 5.6846×1026 kg Saturn is so low that if we could put it in water, it would float on the very surface.

February 5, 1843 astronomers discovered a comet, which was given the name "Great"(aka the March comet, C/1843 D1 and 1843 I). Flying near the Earth in March of the same year, she 'lined' the sky in two with her tail, the length of which reached 800 million kilometers. The earthlings watched the tail trailing the "Great Comet" for more than a month, until, on April 19, 1843, it completely disappeared from the sky.

Martian volcano "Olympus" (Olympus Mons) is the largest in the solar system. Its length is more than 600 km, and its height is 27 km, while the height of the highest point on our planet, the peak of Mount Everest, reaches only 8.5 km.

1 Plutonian year is 248 Earth years.

A solar substance the size of a pinhead, placed in the atmosphere of our planet, will begin to absorb oxygen at an incredible speed and in a split second will destroy all life within a radius of 160 kilometers.
