On our planet a lot of places that are considered to be mystical. Some of them become so because of popular beliefs or set of circumstances, but there are those where there are really strange things that scientists can detect, but can't explain. Perhaps this is a normal stage of development of the planet, but it is possible that it is evidence of the imminent death of everything on Earth. The anomaly, about which speech will go today, not just deviations from normal values, but there are signs of violations of the protection of our planet from a very aggressive space impact. While scientists have found a way to tolerate it, but how long enough for such measures?

South Atlantic magnetic anomaly

This area cannot be described as something mysterious and shrouded in legends, such as the Bermuda triangle and the devil's Sea. In this case we are really dealing with the anomaly, which is very clearly recorded by physicists, but still can not be explained by them.

It all Started in 2009 when the airline Air France, which followed the route from Rio de Janeiro to Paris in 4 hours after the flight disappeared from radar and never made contact. The search operation lasted for several months, but eventually the wreckage was discovered and the experts began to study them.

The investigation revealed an interesting fact. In the end, one of the versions was that the cause of the crash was the failure of the equipment due to the strong exposure to radiation.

the Aircraft of such airlines as Air France don't just disappear.

This fact doesn't attach any importance to until in 2011 the space telescope ”Coro” flying over the Earth at an altitude of 1000 km and making measurements in a flow of protons, found some oddities in their behavior.

Some people

The Problem grew serious, and found that this strange behavior really is, and in the place where contact was lost with the Air France Board, the protons are significantly closer to the planet's surface than in other places. In the end this place gave the name to the South Atlantic magnetic anomaly.

Where is the largest magnetic anomaly

The South Atlantic magnetic anomaly, which is sometimes called Brazilian magnetic anomaly, located in the southern hemisphere and covers a part of the Atlantic ocean and the territory of South America. This has been confirmed by accurate measurements. And determined that the area of this anomaly is 7.8 million square kilometers.

the Magnetic field has made our life what it is.

Through this area is not only aviation, but also water navigation, and even the trajectory of satellites of the Earth.

What's happening in the Brazilian magnetic anomaly

If you keep all the terms, we can say that from the very active solar radiation starts at a distance of approximately 60,000 kilometers from its surface. It is at this distance the atmosphere and magnetic fields are beginning to struggle with emitted by the Sun rays.

At this distance, our planet is struggling with electrons. The protons pass on. Approximately to the level of 1300-1500 km from the planet's surface. And only in the area of the anomaly, we're talking about today, they go even further — approximately to the level of 200 km from the surface of the Earth.

Why is the moon

In the end, most affected by impact of protons is not even ground objects or planes that are substantially below the critical level, and the satellites and space telescopes, flying at an altitude of about 2000 kilometers. The result of such exposure may start working improperly or even fail. In order to avoid this, for a few minutes some of the orbiters off part of his equipment.

Even Hubble is exposed to the Sun.

How did South Atlantic magnetic anomaly

The Appearance of the anomalous magnetic zone is difficult to explain, but many scientists agree that it is a harbinger of major changes of Earth's magnetic field.

All about the Earth's magnetic field, Solar activity and other phenomena in our read .

Many have said that the poles will soon be reversed and the probability of such an outcome no longer seems to be something fantastic. This is more than real. Especially since this has happened many times in the history of our planet. By studying their structure, scientists have confirmed that the periodic shift of the poles is normal and happens about once in 100-200 years. At the same time, they note that last time such a shift was about 600-800 thousand years ago. That is, it can happen anytime. Maybe in 1,000 years, maybe 2,000 years later, maybe later... maybe sooner.

Will Suffer from this all, but that does not mean the death of all life on the planet. Our ancestors and other organisms before them experienced similar turmoil, but the strain they had.

may be 10 times stronger than previously estimated.

In the first place, will go to those animals who feel the field of the Earth and that is what guided during seasonal migration. Will be hard times for us, because magnetic storms can greatly harm all of our technical means, including satellites and communications equipment.

the Sun as if it wanted to kill us but the Earth saysso we did not touch and tries to protect us. Well or just a coincidence.

Taking turns, the magnetic field must first greatly reduced, and then appear again, but in other places. At this point, the field will not protect us from the Sun, but it's not critical, so as to cope with the atmosphere of our planet.

More evidence that there's a big magnetic change are the observations of scientists, which indicate that over the past 150 years the Earth's magnetic field has reduced its intensity by 10%. At the same time, is shifting every year by 20-40 kilometers. There are even arguments and vague evidence that before there were African magnetic anomaly, which has moved and merged with the South Atlantic.

magnetic field is a value that indicates the number of magnetic field lines passing through 1 square centimeter of the cross section of the field.

To Explain this quickly is difficult, as it is created internal processes taking place in the center of the Earth. It is believed that if they completely stop, then the field must change very slowly and it should be enough for another 7-12 thousand years. Against this background, such strong changes in just hundreds of years seem strange. Most likely, we just don't know something or just can't explain. Actually, it says the word ”anomaly”.

Abnormalities are found in many places, but that is the South Atlantic magnetic anomaly is the most serious.
