Nuclear explosion in space. Why are solar flares dangerous? Solar flares - why and how dangerous? Powerful explosion in the sun

This process is called a supernova explosion. A series of strong flares on the star that we observe on the Sun throughout September indicates a high probability of such a scenario.

ON THIS TOPIC

"Activation processes in our luminary in recent times noticeable. Among them, of course, are the current powerful outbreaks. However, to be honest, we still cannot give an unambiguous answer to the question of whether the Sun will die in the foreseeable future. We still know too little about the star closest to us, about what is happening to it," said research physicist Ivan Nazarenko.

According to him, if fears are confirmed and a supernova forms, earthlings will see a bright flash eight minutes later. "The whole sky will be covered by a glow from a bright white flame emitted by an exploded star. The power of this glow will be such that the night on the planet will disappear. Most likely, all living things, including people, will die at the first stage of the cataclysm," the scientist suggested.

Further, streams of radioactive radiation will fall on the planet. Under the influence of abnormal solar radiation, the temperature on the Earth's surface will rise to five thousand degrees, and all the water will evaporate and form a thick cloud cover at an altitude of tens of kilometers.

But this is not the end, the expert warned. When, due to the explosion, the Sun increases many times in size, plasma flows will reach the Earth. After that, the planet will deorbit and go on an unpredictable space "journey".

A bright flash, which was recorded on September 6, 2017 on the nearest line from the Earth, will most strongly affect life on our planet for at least another five days. The fact that The most powerful explosion on the Sun in 12 years, will be a real test of strength for all people.

Powerful explosion on the Sun 2017

Unusual a natural phenomenon on the day Star has already caused an increase in the X-ray background over the entire surface of the Earth. In the coming days, people will encounter interference in GPS navigation, radio communications, and also see the real Polar Lights over the territory of the Moscow region.

The last time an outbreak of such power was recorded in September 2005, it was assigned the highest score of solar activity X9.3. On a color scale, this corresponds to the maximum, black level of solar activity. There is, made by one futurologist

This is provided that usually geomagnetic radiations vary within green, yellow, red and violet colors.

Solar flare consequences

Scientists warn that the highest level of geomagnetic disturbance will affect the operation of the equipment of aircraft and space objects, as well as lead to x-ray exposure of passengers.

After a powerful solar flare has occurred, a real geomagnetic storm awaits the inhabitants of the Earth. A super-powerful flash has made its own adjustments to, so weather-dependent people need to quickly take precautions.

The consequences of explosions on the Sun are fraught with emotional instability, sudden accidents at work, major accidents, as well as deterioration in well-being. In the period from 6 to 15 September, direct sunlight should be avoided on the skin. It is better not to carry out planned operations at this time, and also refuse to go to a beauty salon. Be prepared for the fact that people will react more sharply than usual to your words. Consciously protect yourself from communicating with inadequate personalities and spend more time outdoors.

What's Happening to the Sun in 2017

Astrologers say that such powerful solar flares, as in September 2017, are directly related to the full solar eclipse August 21, 2017.

In the year of the Fire Rooster, the daytime star experiences one magnetic storm after another, which affects the life of the entire Earth.

Such fluctuations in solar activity have already brought the inhabitants of the United States the devastating hurricane Harvey, but in Europe it suddenly snowed in the first days of September. In Russia, solar flares will lead to massive outages in mobile communications, problems with electricity, as well as an increase in the number of heart attacks, strokes and mental disorders in people. Among the positive aspects: a great opportunity to see the aurora in the night sky on September 7-9, not only in regions such as the Irkutsk region, Tyumen, Kirov, but also in the city of Moscow and the Moscow region.

On September 6, 2017, the largest solar flare occurred in twelve years. The registered radiation shows that a coronal mass ejection has occurred. Life figured out how this could threaten ordinary people.

Behind the fuss ordinary days and simple momentary problems, we forget how complex and fragile our world is. That the Sun is not just a luminous basketball in the sky, giving light during the day and the opportunity to take beautiful photos in the mornings and evenings, but huge star, whose mass is 99.87 percent of the mass of the entire solar system. On September 6, another reminder happened - the largest flare in the last twelve years occurred on the Sun.

It's time to figure out what it can threaten us, ordinary earthlings, astronauts at the International space station, which do not have the saving protection of the atmosphere, and even satellites operating in Earth's orbit.

Flash on the right!

Let's deal with the terms. What is a flash, if the Sun is already a huge ball, consisting mainly of hydrogen, inside which thermonuclear reactions, releasing a gigantic amount of energy, light and heat. Yes, this is true, but due to its structure, the Sun "burns" fairly evenly for its size and mass.

However, sometimes there is an explosive release of energy in the Sun's atmosphere, called a flare. This process captures all layers of the solar atmosphere: the photosphere, chromosphere and corona of the Sun. At this moment (and the impulse phase solar flares lasts only a few minutes) there is a powerful release of energy - sometimes up to 15 percent of the total energy released by the Sun per second.

Even just converting the flare energy into close and understandable values ​​is very difficult - it is so huge. A powerful flash releases about 160 billion megatons of TNT energy, which, by comparison, is the approximate amount of world electricity consumption over one million years.

Sometimes at the same moment there is also a coronal mass ejection - part of the solar matter is ejected with force outside the atmosphere of the Sun. Scientists have not yet determined whether these phenomena are related or not. Quite often, solar matter is ejected parallel to flares, but sometimes this occurs independently of each other. On September 6, the Sun experienced not only a flare, but also a coronal mass ejection.

The ejection contains a plasma consisting of electrons and protons. The ejection mass can be up to 10 billion tons of matter that flies in space with average speed 400 kilometers per second and reaches the Earth within one - three days. And if the main effect of a solar flare reaches the Earth in eight and a half minutes, then in the case of a coronal mass ejection, the effect turns out to be extended and begins several days after the ejection moment.

It is worth noting that the Sun is a ball, so some of the flares from the Earth are simply not visible. They occur on the opposite side of the Sun and do not affect us in any way. In this case, the Earth was not lucky: the outbreak happened in a geoeffective area near the Sun-Earth line, from where the impact on our planet is maximum.

Scientists began to measure the power of solar flares and record coronal mass ejections relatively recently, since the sixties of the last century. Flash output is indicated by the Latin letters A, B, C, M or X and numerical value for her. The flare that occurred is estimated by scientists as X9.3, while the most powerful flare ever recorded is X28. Strangest of all, the current outbreak occurred exactly twelve years after the last outbreak of such magnitude (September 7, 2005). In addition, now is a period of decline in solar activity. Astronomers did not expect such a phenomenon to occur.

What threatens such an outbreak?

interacting with the Earth's magnetosphere, plasma flows cause disturbances in it - storms that are felt by weather-dependent people.

The thing is that the human body is accustomed to the Earth's magnetic field and uses it in Everyday life, for example, for orientation in space. The perturbations magnetic field cause an imbalance in the body systems in some people who are most sensitive to this phenomenon. It is believed that geomagnetic storms cause migraines, insomnia, pressure surges. However, all this is purely individual. It is difficult to say how geomagnetic storms caused by solar flares affect a specific person. Scientists are still studying this issue, there is even a whole section of biophysics that studies the effect of changes in the activity of the Sun on terrestrial organisms - heliobiology.

So the most important thing is not to panic. As a rule, weather-dependent people are well aware that they can get sick from geo magnetic storms. Meteorologically dependent, as well as people with chronic diseases, should monitor the approach of magnetic storms and exclude in advance any events or actions that can lead to stress during this period. It is best at this time to be at rest, relax and reduce any physical and emotional overload.

What's with the connection?

Soyuz", which plays the role of a rescue ship on the ISS. However, the design of all station modules provides normal protection for the crew from bursts of solar activity, during which the radiation background. Cosmonauts daily carry out an individual account of the dose of radiation received on board.

In general, there is no need to be afraid of solar flares. This is a fairly common occurrence, in your life you have experienced many of them without even knowing what happened. Otherwise, you can become like Dunno from the Flower City and make a commotion from scratch.

And Dunno ran at full speed home and let's shout:

Brothers, save yourself! The piece is flying!

- What piece? they ask him.

- Piece, brothers! A piece broke off from the Sun. Soon it will slap - and everyone will be covered. Do you know what the sun is? It is larger than our entire Earth!

- What are you thinking!

- I'm not imagining anything. This is what Steklyashkin said. He saw through his pipe.

Everyone ran out into the yard and began to look at the sun. They watched and watched until tears began to flow from their eyes. Blindly, it began to seem to everyone that the Sun was actually chipped. And Dunno shouted: "Save yourself who can! Trouble!"

Apocalypse on the "Second Earth" destroyed the hopes of scientists to search for intelligent life close to the solar system.

The star closest to the Sun exploded: the world is waiting for the end of the world

Astronomers have recorded an extraordinary powerful flash at the nearest solar system star, Proxima Centauri. This star belongs to the class of red dwarfs - the most common in the galaxy. Milky Way, writes "RG".

The outbreak of Proxima Centauri occurred on March 24, 2017. The peak luminosity of the star was 2x10 14 erg per second, which is an order of magnitude greater than the maximum intensity of solar flares. The spectral power of the radiation flux during intkbbee outbreaks increased a thousand times.

Scientists note that the exact causes of the anomalously strong energy release are still unknown, but they tend to associate it with the synchrotron effect: the magnetic field of the star accelerates electrons to near-light speeds, after which the particles begin to radiate in the radio range.

The end of the world on the "second Earth" puzzled scientists

The Centaurus star system is the closest to us. It is just over 4 light years away. There are three stars in the system - Alpha Centauri A, Alpha Centauri B and Proxima Centauri. Two stars - A and B - are similar to our Sun both in characteristics and in size. Proxima Centauri is a red dwarf.

Scientists did not rule out that the discovered planet has both an atmosphere and oceans, they called it the "second Earth", they believed that someone could live there - up to intelligent beings. Komsomolskaya Pravda notes that the outbreak was discovered recently - American astrophysicists, led by Meredith McGregor from the Carnegie Institute, looked through the collected data and stumbled upon a phenomenal phenomenon.

It turned out that the flare on Proxima Centauri was 10 times more powerful than similar flares that had ever occurred on the Sun. At the same time, the dose of deadly radiation was 4 thousand times higher than the level created by our luminary.

That is, if there was life on a planet orbiting Proxima Centauri, now it is gone. Living beings are hardly capable of surviving such a monstrous cataclysm.

The explosion on the Sun on 09/06/2017 was the strongest in the last 12 years. The Solar X-Ray Astronomy Laboratory of the Lebedev Physical Institute of the Russian Academy of Sciences told REGNUM that the flare was the result of the coordination of the two largest groups of sunspots. As we have already reported, the energy was released in a unique X9.3 explosion.

The flare occurred against the backdrop of reduced solar activity. In the 20-year history of observing the Sun, more powerful explosions have occurred only 5 times. The anomaly happened near the Sun-Earth line, and therefore the impact of the emergency on our planet will be maximum - today a magnetic storm has begun, and earthlings will feel the impact of the explosion for a week. Weather dependent and people with chronic diseases should pay close attention to their health.

Solar flare on September 6, 2017: consequences

The consequences of the outbreak for the Earth are still difficult to assess. “It affects everything. For health, for the weather. But on the weather, of course, not in the long term, ”Georgy Goncharov, a leading researcher at the Pulkovo Observatory of the Russian Academy of Sciences, shared with REN TV. The expert believes that on Friday evening the number of fatal accidents will increase sharply. It is also necessary to closely monitor the condition of children under 12 years of age.

There have already been reports in the media about a deterioration in the quality of communications both in Europe and in the United States, as well as about the failure of space technology. However, the northern lights can be seen even at the latitude of Moscow. NASA's Solar Dynamics Observatory has published images of the space phenomenon.
