Every second the Sun sends huge amounts of energy, whose intensity is so high that it would instantly end all life on the planet, if the operation of the magnetic field of the Earth at some point gave even the most minor glitch. Absorbing a large amount of charged particles, the magnetic shield of our blue planet creates a fascinating Aurora, which can be observed at high latitudes of the Earth. However, in the history of our world already happened events that can completely destroy the already fragile atmosphere the only refuge of man in the Universe. In addition, the solar storms the destructive force may occur more frequently than previously thought. So what about this say the all-knowing scientists?
How dangerous is solar wind?
Despite the fact that the Sun is a quite ordinary yellow star average luminosity periodically and it is able to amaze humanity with its rebellious disposition. Severe manifestations of space weather that we know as solar storms compress the magnetic shield of the Earth, releasing enough energy to permanently deprive the city and even the country’s access to electricity. Blinding satellites, disrupting radio signals and disabling all electrical appliances, solar storms are still among the most dangerous for the development of mankind of phenomena of the universe around us. According to an article published on the portal livescience.comstrong bursts of electromagnetic activity of our star may even occur more frequently than previously assumed.
So, in the new study space weather, scientists analyzed the catalog changes in the magnetic field of the Earth, since 1868. It turned out that the years which have shown the strongest bursts of geomagnetic activity, coinciding with the strongest solar storms in history. It was discovered that severe storms can disrupt some satellites and communication systems occurred in 42 of the last 150 years, while the most extreme storms, which caused even more significant damage to occur once in 25 years.
The earliest mention of the manifestations of solar storms was recorded in the late nineteenth century, when disruptions in Telegraph were first mentioned in official documents. As soon as the spread of radio and aviation technology gradually began to gain its momentum, the appearance of auroras in the Northern latitudes of our planet increasingly has become associated with a mysterious disruption of electrical equipment. One of the most important cases of that time was a geomagnetic storm in may of 1921, which caused massive disruptions in radio and Telegraph around the world. Sources claim that the Northern and Southern lights were then observed in lower latitudes than usual, and one of the observatories claimed that she discovered the southern Cape of the island of Samoa, located just 13 degrees South of the geomagnetic equator.
Another striking case of the manifestation of the hot-tempered nature of our Sun was a powerful flash, swept over our planet in November of 2003. Then the high-energy charge disrupted the operation of satellites and led to the failure of several spacecraft. Nearly two decades after the last powerful solar storm, when we are as never before dependent on satellites and electricity, the Earth once again stood on the brink of yet another potentially damaging event, the consequences of which we can only guess.
