Scientists from the Netherlands have discovered a star 24 thousand light years from Earth that, according to the laws of physics, cannot exist. The unusual object that interested astrophysicists is located in the constellation Cassiopeia as part of the binary system Swift J0243.6+6124 and is a neutron star that was formed as a result of a Supernova explosion, writes Science Alert.
As scientists note, after the explosion, most of the star’s mass “disappears” in space, and the core becomes a super-dense object with strong gravity. If the star is smaller than “about three solar masses,” it becomes a neutron star; if larger, it becomes a black hole. In this case, an accretion disk is formed around the neutron star - a structure that consists of matter rotating around the central body. The matter of the disk, under the influence of gravity, falls in a spiral onto the central star, and heating occurs, which generates electromagnetic radiation, the wavelength of which depends on the type of star.
Previously, it was believed that the disks around young stars and protostars emit in the long-wavelength (infrared) range, and those around compact massive objects such as neutron stars and black holes - in the short-wavelength (X-ray). At the same time, the star must have an extremely weak magnetic field - until recently, relative jets were not discovered in stars with a powerful magnetic field; it was believed that it prevented the formation of jets.
However, analysis of data from Swift J0243 showed that the star spews relativistic jets, although its magnetic field is 10 trillion times stronger than that of the Sun. Previously, a similar phenomenon was observed only in neutron stars with magnetic fields 1000 times weaker.
“The radio frequency spectrum of Swift J0243 is the same as that of jets from other sources and evolves in the same way. The brightness of the radio emission also follows the brightness in the falling gas, as seen in other jet systems. But for the first time, we observed a jet of a neutron star with a strong magnetic field,” said the leader of the study, astronomer Jacob van den Eijenden from the University of Amsterdam.
This discovery refutes the theory that jets are suppressed by a magnetic field. According to a preliminary hypothesis, the solution to the mystery of Swift J0243.6+6124 is that the jets were able to form in such a strong magnetic field due to the large amount of rotational energy of the disk, but this assumption remains to be proven.

Since childhood, we have been learning elementary truths about the structure of the Universe: all planets are round, there is nothing in space, the sun is burning. Meanwhile, this is all untrue. Not in vain new minister education and science Olga Vasilyeva recently stated that it is necessary to return astronomy lessons to school. Editorial Medialeaks fully supports this initiative and invites readers to update their ideas about planets and stars.
1. The earth is a smooth ball
The real shape of the Earth is slightly different from the globe from the store. Many people know that our planet is slightly flattened at the poles. But besides this, different points on the earth’s surface are located at different distances from the center of the core. It's not just the relief, it's just that the whole Earth is uneven. For clarity, use this slightly exaggerated illustration.
Closer to the equator, the planet generally has a kind of protrusion. Therefore, for example, the most distant point on the earth’s surface from the center of the planet is not Everest (8848 m), but the Chimborazo volcano (6268 m) - its peak is 2.5 km further. This is not visible in photographs from space, since the deviation from the ideal ball is no more than 0.5% of the radius, in addition, the imperfections in the appearance of our beloved planet are smoothed out by the atmosphere. The correct name for the shape of the Earth is geoid.
2. The sun is burning
We are used to thinking that the Sun is a huge ball of fire, so it seems to us that it is burning, there is a flame on its surface. In fact, combustion is chemical reaction, which requires an oxidizer and fuel, requires an atmosphere. (By the way, this is why explosions in outer space are practically impossible).
The sun is a huge piece of plasma in a state of thermonuclear reaction; it does not burn, but glows, emitting a stream of photons and charged particles. That is, the Sun is not fire, it is a large and very, very warm light.
3. The Earth rotates on its axis in exactly 24 hours
It often seems that some days pass faster, others slower. Oddly enough, this is true. A solar day, that is, the time it takes for the Sun to return to the same position in the sky, varies by plus or minus about 8 minutes at different times of the year in different parts of the planet. This is due to the fact that the linear speed of motion and the angular speed of rotation of the Earth around the Sun are constantly changing as it moves along an elliptical orbit. The day either increases slightly or decreases slightly.
In addition to the solar day, there is also a sidereal day - the time during which the Earth makes one revolution around its axis in relation to distant stars. They are more constant, their duration is 23 hours 56 minutes 04 seconds.
4. Complete weightlessness in orbit
It is commonly believed that an astronaut space station is in a state of complete weightlessness and its weight is zero. Yes, the influence of the Earth’s gravity at an altitude of 100-200 km from its surface is less noticeable, but remains just as powerful: that is why the ISS and the people in it remain in orbit, and do not fly in a straight line into outer space.
If we talk in simple language, both the station and the astronauts in it are in an endless free fall (only they are not falling down, but forward), and the very rotation of the station around the planet maintains the soaring. It would be more correct to call it microgravity. A state close to complete weightlessness can only be experienced outside the Earth's gravitational field.
5. Instant death in space without a spacesuit
Oddly enough, for a man who fell out of a hatch without a spacesuit spaceship, death is not so inevitable. It will not turn into an icicle: yes, the temperature in outer space is -270 °C, but heat exchange in a vacuum is impossible, so the body, on the contrary, will begin to heat up. Internal pressure is also not enough to explode a person from the inside.
The main danger is explosive decompression: gas bubbles in the blood will begin to expand, but theoretically this can be survived. In addition, in space conditions there is not enough pressure to maintain the liquid state of the substance, so water will begin to evaporate very quickly from the mucous membranes of the body (tongue, eyes, lungs). In earth's orbit under direct sunlight, instant burns to unprotected areas of the skin are inevitable (by the way, the temperature here will be like in a sauna - about 100 °C). All this is very unpleasant, but not fatal. It is very important to be in space while exhaling (air retention will lead to barotrauma).
As a result, according to NASA scientists, under certain conditions there is a chance that 30-60 seconds in outer space will not cause damage. human body, incompatible with life. Death will ultimately come from suffocation.
6. The asteroid belt is a dangerous place for starships
Science-fiction films have taught us that asteroid clusters are piles of space debris that fly in close proximity to each other. On maps of the Solar System, the Asteroid Belt also usually looks like a serious obstacle. Yes, this place is very high density celestial bodies, but only by cosmic standards: half-kilometer blocks fly at a distance of hundreds of thousands of kilometers from each other.
Humanity has launched about a dozen probes that went beyond the orbit of Mars and flew to the orbit of Jupiter without the slightest problem. Impenetrable clusters of space rocks and rocks, like those seen in Star Wars, may be the result of the collision of two massive celestial bodies. And then - not for long.
7. We see millions of stars
Until recently, the expression “myriad stars” was nothing more than a rhetorical exaggeration. With the naked eye from Earth in the clearest weather, no more than 2-3 thousand celestial bodies can be seen at the same time. In total in both hemispheres - about 6 thousand. But in the photographs of modern telescopes you can actually find hundreds of millions, if not billions of stars (no one has counted yet).
The newly acquired Hubble Ultra Deep Field image captures about 10,000 galaxies, the most distant of which are approximately 13.5 billion light-years away. According to scientists' calculations, these ultra-distant star clusters appeared “only” 400-800 million years after the Big Bang.
8. The stars are motionless
It is not the stars that move across the sky, but the Earth that rotates - until the 18th century, scientists were sure that, with the exception of planets and comets, most of the celestial bodies remained motionless. However, over time it was proven that all stars and galaxies without exception are in motion. If we went back several tens of thousands of years ago, we would not recognize the starry sky above our heads (as well as the moral law, by the way).
Of course, this happens slowly, but individual stars change their position in outer space in such a way that this becomes noticeable after just a few years of observations. Bernard's star "flies" the fastest - its speed is 110 km/s. Galaxies also shift.
For example, the Andromeda Nebula, visible to the naked eye from Earth, is approaching the Milky Way at a speed of about 140 km/s. In about 5 billion years we will collide.
9. The Moon Has a Dark Side
The Moon always faces the Earth with one side, because its rotation around its own axis and around our planet is synchronized. However, this does not mean that the rays of the Sun never fall on the half invisible to us.
During the new moon, when the side facing the Earth is completely in shadow, the opposite side is completely illuminated. However, on natural satellite On Earth, day gives way to night somewhat more slowly. A full lunar day lasts approximately two weeks.
10. Mercury is the hottest planet in solar system
It is quite logical to assume that the planet closest to the Sun is also the hottest in our system. That's also not true. The maximum temperature on the surface of Mercury is 427 °C. This is less than on Venus, where a temperature of 477 °C is recorded. The second planet is almost 50 million km further from the Sun than the first, but Venus has a dense atmosphere of carbon dioxide, which, due to the greenhouse effect, retains and accumulates temperature, while Mercury has practically no atmosphere.
There is one more point. Mercury completes a full revolution around its axis in 58 Earth days. A two-month night cools the surface to -173 °C, meaning the average temperature at Mercury's equator is about 300 °C. And at the planet’s poles, which always remain in the shadows, there is even ice.
11. The solar system consists of nine planets
Since childhood, we are accustomed to thinking that the solar system has nine planets. Pluto was discovered in 1930, and for more than 70 years it remained a full member of the planetary pantheon. However, after much debate, in 2006, Pluto was demoted to the rank of the largest dwarf planet in our system. The fact is that this celestial body does not correspond to one of the three definitions of a planet, according to which such an object must clear the surroundings of its orbit with its mass. Pluto's mass is only 7% of the total weight of all Kuiper Belt objects. For example, another planetoid from this region, Eris, is only 40 km smaller in diameter than Pluto, but noticeably heavier. For comparison, the Earth's mass is 1.7 million times greater than that of all other bodies in the vicinity of its orbit. That is, there are still eight full-fledged planets in the solar system.
12. Exoplanets are similar to Earth
Almost every month, astronomers delight us with reports that they have discovered another exoplanet on which life could theoretically exist. The imagination immediately pictures a green-blue ball somewhere near Proxima Centauri, where it will be possible to dump it when our Earth finally breaks. In fact, scientists have no idea what exoplanets look like or what their conditions are like. The fact is that they are so far away that modern methods We cannot yet calculate their actual size, atmospheric composition and surface temperature.
As a rule, only the estimated distance between such a planet and its star is known. Of the hundreds of exoplanets found that are located inside the habitable zone, potentially suitable for supporting Earth-like life, only a few could potentially be similar to our home planet.
13. Jupiter and Saturn are balls of gas
We all know that the largest planets in the solar system are gas giants, but this does not mean that, once in the gravitational zone of these planets, the body will fall through them until it reaches the solid core.
Jupiter and Saturn are composed primarily of hydrogen and helium. Under the clouds, at a depth of several thousand km, a layer begins in which hydrogen, under the influence of monstrous pressure, gradually transforms from gaseous to the state of liquid boiling metal. The temperature of this substance reaches 6 thousand °C. Interestingly, Saturn emits into space 2.5 times more energy that the planet receives from the Sun, but it is not yet entirely clear why.
14. In the solar system, life can only exist on Earth
If there was something similar to earthly life existed somewhere else in the solar system, we would have noticed it... Right? For example, on Earth, the first organic matter appeared more than 4 billion years ago, but for another hundreds of millions of years, not a single external observer would have seen any obvious signs of life, and the first multicellular organisms appeared only after 3 billion years. In fact, besides Mars, there are at least two more places in our system where life could well exist: these are the satellites of Saturn - Titan and Enceladus.
Titan has a dense atmosphere, as well as seas, lakes and rivers - although not made of water, but of liquid methane. But in 2010, scientists from NASA announced that they had discovered on this satellite of Saturn signs of the possible existence of the simplest forms of life, using methane and hydrogen instead of water and oxygen.
Enceladus is covered with a thick layer of ice, it would seem, what kind of life is there? However, below the surface at a depth of 30-40 km, as planetary scientists are sure, there is an ocean of liquid water approximately 10 km thick. The core of Enceladus is hot and this ocean may contain hydrothermal vents similar to Earth's “black smokers.” According to one hypothesis, life on Earth appeared precisely thanks to this phenomenon, so why not the same thing happen on Enceladus. By the way, in some places the water breaks through the ice and erupts out into fountains up to 250 km high. Recent evidence confirms that this water contains organic compounds.
15. Space is empty
There is nothing in interplanetary and interstellar space, many are sure from childhood. In fact, the vacuum of space is not absolute: in microscopic quantities there are atoms and molecules, relic radiation that remains from the Big Bang, and cosmic rays, which contain ionized atomic nuclei and various subatomic particles.
Moreover, scientists have recently suggested that the void of space is actually made of matter that we cannot yet detect. Physicists called this hypothetical phenomenon dark energy and dark matter. Presumably, our Universe consists of 76% dark energy, 22% of dark matter, 3.6% - from interstellar gas. Our ordinary baryonic matter: stars, planets, etc. is only 0.4% of the total mass of the universe.
There is an assumption that it is the increase in the amount of dark energy that causes the Universe to expand. Sooner or later, this alternative entity, in theory, will tear the atoms of our reality into shreds of individual bosons and quarks. However, by that time, neither Olga Vasilyeva, nor astronomy lessons, nor humanity, nor the Earth, nor the Sun will exist for several billion years.
Humanity has been looking at the sky for thousands of years, and all we have learned in that time is that space is a crazy place. Every day, scientists discover a large number of strange things that give rise to new questions, inspire fear and cause incredible admiration.
1. The smell of rum and raspberries in the center of the galaxy
The Sagittarius B2 cloud is several million times the mass of the Sun and floats around our Milky Way galaxy. Scientists recently discovered that the cloud is basically a giant river of raspberry rum.
The fact is that Sagittarius B2 contains 10 billion billion billion liters of alcohol and molecules called ethyl formate. It is this substance that gives raspberries a sweet taste, and rum its distinctive smell. However, the origin of these molecules remains a mystery to scientists, so the opening of the intergalactic pub should be postponed.
2. Mickey Mouse
Astronomers from the USA, studying the surface of the planet Mercury, discovered 3 craters that in their shape resemble the silhouette of Mickey Mouse. Scientists have said that it was from space that Disney got his ideas.
Of course, serious scientists are just joking. And they can be understood: every day they receive thousands of letters from enthusiasts who have found another crater that looks like this or that object.
3. The truth about the shooting star
Everyone knows that shooting stars are meteorites that hit the atmosphere. But many people don't know that shooting stars actually exist.
When a supermassive black hole engulfs a binary star system, one star is swallowed up by the black hole and the other is shot out of the way like a giant slingshot. Just imagine a huge fireball of gas, 4 times the size of our Sun, traveling at millions of kilometers per hour. It doesn't sound so romantic anymore.
You've probably heard that it rains diamonds on Jupiter and Saturn. But what about a planet that is itself a huge diamond?
Exoplanet PSR J1719-1438 b was discovered in 2009. It is located 3,900 light years away from us. And 1/3 of the planet’s mass is pure diamond, the rest is graphite. According to scientists, on such planets there may be areas completely covered with kilometers of diamonds (diamond fields).
5. Eye of Sauron
If you look up at night, you may see one of the brightest stars in the sky - Fomalhaut. It is located near our Milky Way galaxy and is 2.3 times heavier than the Sun.
Scientists studied the star for a long time, but the real magic happened when, using the latest equipment, they took pictures of it in an infrared filter. It turned out that Fomalhaut is similar to the famous eye of Sauron from the film “The Lord of the Rings”.
The black area in the center is the star itself, and the oval around it is space debris. It looks creepy, but beautiful.
No metaphors. Indeed, at a distance of 10 billion light years from us, the largest reservoir of water in the Universe is located. This rain cloud is 100 thousand times larger than the Sun, contains 140 trillion times more water than the world's oceans, and, as scientists suggest, it envelops a supermassive black hole.
“Now that we know about it, we can only hope that the wind will not blow in our direction,” astronomers joke.
7. Message
But this thing in space may be found by another alien civilization. Voyager was launched in 1977 and is still exploring space. Thanks to him, we have photographs of the Earth from a distance of 6 billion km, as well as photographs of Jupiter and Saturn. But the most interesting thing is what is attached to the device itself.
On the body of Voyager there is a golden record on which greetings are recorded in 55 languages, music of different nations, human voices, sounds of nature, 100 photographs and coordinates of planet Earth. This message was sent in the hope that the device will be noticed by some extraterrestrial civilization.
8. Huge lens
One of the most interesting discoveries is the gravitational lens. This is a formation in space, the mass of which is so great that with its gravitational field it bends the direction of electromagnetic radiation. Just like a regular magnifying glass bends a beam of light.
That is, when we look through a cosmic lens, we see an object outside our field of vision and slightly distorted. Thanks to such lenses, scientists can observe objects that are located in other galaxies.
9. Dark Stream
Scientists say that there is something huge beyond our visible Universe. We cannot see what it is, but we observe that it is something that is drawing in parts of neighboring Universes, like a drainage water.
Scientists called this thing the Dark Stream because it was the only name that sounded quite mysterious and ominous. Some astrophysicists believe that this is the edge of another large Universe, which is moving towards ours. But there is no exact answer yet, so we just have to wait until a more powerful telescope is invented.
As we open up space more and more, we dream of colonizing other planets and meeting other life forms. For generations, space has captured our imaginations and even ruled our lives. We present to your attention some new and amazing discoveries related to space.
Planets like Earth
In 2013, astronomers confirmed the existence of about 20 billion exoplanets in our Milky Way Galaxy alone that are similar to Earth and could harbor life. Given the billions of galaxies in the Universe, there could be billions of billions of planets theoretically suitable for life.
Pluto is still a planet
In 2006, amateur astronomers were shocked to learn that Pluto had been "downgraded" to a dwarf planet. Those who refused to accept this fact were rewarded in 2015 when spacecraft New Horizons discovered that Pluto is more of a planet after all. Its gravity is strong enough to hold onto the atmosphere and deflect charged particles from the solar wind.
Collision of golden stars
2013 was a fantastic year for astronomy. Astronomers have discovered the collision of two stars, during which an incredible amount of gold was formed, weighing many times the mass of our Moon.
Tsunami on Mars
Scientists recently revealed a discovery that has boggled the minds of many in the space community: They provided evidence that once large tsunamis may have altered the Martian landscape. Two meteorite impacts caused huge tidal waves that rose to a height of about 50 meters!
Planet Godzilla
Our planet is one of the largest rocky planets, but in 2014 scientists discovered a planet 2 times larger and 17 times heavier than Earth. Although planets this size were considered gas giants, this planet, named Kepler10c, is surprisingly similar to ours. She was also given the nickname "Godzilla".
Gravitational waves
Back in 1916, Albert Einstein announced the existence of gravitational waves, almost a hundred years before scientists confirmed their existence. The science world was delighted by the discovery made in 2015. Spacetime can pulsate like still water in a pond if you throw a stone into it.
Formation of mountains on a volcanic satellite
New research has shown how mountains form on Jupiter's volcanic moon Io. While mountains on Earth form in long chains, Io's mountains are mostly solitary. On this moon, volcanic activity is so great that a 13-centimeter layer of molten lava covers its surface every 10 years. Given this rapid rate of eruptions, scientists have concluded that the enormous pressure on Io's core is causing rifts to rise to the surface to "release" excess pressure.
New ring of Saturn
Astronomers recently discovered a huge new ring around Saturn. It is located 3.7 - 11.1 million kilometers from the planet's surface and rotates in the opposite direction compared to the other rings. The new ring is so rarefied that a billion Earths could fit in it. Because the ring is quite cold, approximately minus 196 degrees Celsius, it was only recently discovered using an infrared telescope.
The oldest star in the Universe
A few hundred million years is a tiny fraction of the time for the Universe, since its age is 14 billion years. The oldest star known to people- SMSS J031300.36-670839.3. Its age is about 13.6 billion years.
Oxygen in space
Oxygen is naturally an extremely reactive gas, which causes it to interact with other elements existing in the universe. The discovery of molecular oxygen - the same type that humans breathe - in the atmosphere of the notorious comet 67P has deepened people's knowledge of cosmic gases and raised hopes that oxygen may exist in other parts of the universe, in a form that humans can use.
Hyperactive galaxy
In 2008, a Galaxy was discovered 12.2 billion light-years from Earth in which stars are forming extremely quickly. In our Milky Way, a new star is born on average every 36 days; in a galaxy called the Baby Boom, a new star is born every 2 hours.
The coldest place in the Universe
The coldest place in the Universe is the Boomerang Nebula, the temperature there is near absolute zero. This nebula glows bright blue due to light reflecting off its dust.
Smallest planet
The smallest planet to date was discovered in 2013. Its name is Kepler-37b. It is slightly larger than the Moon, but 3 times closer to its star than Mercury is to the Sun. Thanks to this, the temperature on its surface is 425 degrees Celsius.
Stars dying prematurely
In 2016, it was discovered that some stars in an active star-forming region called the Carina Nebula are dying prematurely. About half of the stars in this location skip the red giant stage in their development, thereby shortening their life cycle by millions of years. It is unknown what causes this effect, but it has only been seen in sodium-rich or oxygen-poor stars.
A new place for humanity to live
Some scientists believe that in order to detect life, it is necessary to pay attention to the satellites of other planets. For example, as it passes Jupiter, its icy moon Europa shoots 6,800 kg of water per second into the air from geysers at its south pole. Scientists have recently developed a project to analyze the content of this water before it falls back to the planet's surface. Such research could help determine whether life exists on Europa.
Giant Diamond Star
The star BPM 37093, nicknamed "Lucy", is a white dwarf star located approximately 20 light-years from Earth. It is noteworthy that it is a giant diamond the size of the Moon. Jewelers would value it at 10 decillion carats (a decillion is 1060).
The real ninth planet
Although Pluto has been "demoted", scientists believe there may be a huge planet orbiting the Sun behind Pluto. Using mathematical laws, scientists have determined that there must be a Neptune-sized planet orbiting in distant orbit, but it has still not been found.
Vacuum noise
In September 2013, NASA released audio recordings of plasma waves, the first sounds ever recorded in interstellar space.
The brightest supernova
Discovered in 2015, ASASSN-15lh is the brightest supernova. It shines 570 billion times brighter than the Sun. Even stranger, scientists discovered that supernova activity increased a second time about two months after the star passed its peak brightness.
Asteroid with rings
Although it is common for large gas giants to have orbital ring systems, rings are quite rare among other celestial bodies. Scientists were delighted to find them around the asteroid Chariklo. The asteroid has two rings, likely formed from frozen water as a result of a collision with another celestial object.
Alcohol Comet
Comet Lovejoy delighted astronomers and drinkers in 2015. While studying the fast-moving piece of ice, scientists discovered that the comet was spewing out the same type of alcohol that humans drink at the rate of 500 bottles of wine per second.
Guys, we put our soul into the site. Thank you for that
