'Tsunami' the sun hit the earth

On June 7, the United States Aeronautics and Space Administration (Nasa) officially announced that a massive "tsunami" of solar charge from the sun was landing on the earth.

According to NASA , after a long time watching the sunspots on the sun, the agency's scientists said: A huge energy has been released from the largest black spot on the sun with huge charge landed on earth according to the wind. In experts, this phenomenon is also called magnetic storm .

It is known that the solar wind has carried particles of charged particles escaping from the upper part of the sun. Because of carrying high-energy electrons and protons , the solar wind can escape the gravitational pull of stars. In addition to magnetic storms, solar wind also causes aurora (occurs after charged particles in the solar wind interact with the magnetic field of the planet) and many other phenomena.

A month ago NASA scientists observed Noaa 9393 - the largest black spot on the sun, when it was not as large as it is today. In recent times, they were surprised to see this black mark expand too quickly. Noaa 9393 constantly has signs that its pent-up energy is about to explode. Mr. Joe Elrod, US Solar Observatory, said: ' This is the first large black spot that we observed during a solar cycle . '

This year, the sun at the top of the cycle, black spots appear a lot . By the end of March, scientists identified nearly 300 traces, of which the largest was Noaa 9393, covering an area 13 times larger than the earth. Its size is so huge that it can be viewed directly with the naked eye.

When a black spot explodes, it will produce billions of tons of ionized particles and gases, pointing towards the Earth, changing the magnetic field. This can threaten the electrical system and telecommunications satellites in orbit and below the ground, while altering the climate of the planet.

According to the scientists, this solar 'tsunami' from the sun could cripple the activity of artificial satellites and even attack the electrical networks on the ground. Therefore, due to turbulence, some flights where this 'tsunami' wave passes will also be affected. Not only that, it will also adversely affect the ozone layer, causing some negative impacts on human health, but not serious.

A scientist at NASA said: 'The storm from this time only lasts 12 to 24 hours, then dissipates. So their influence on human health is not great. The place most affected by the storm this time is in Eastern Europe and Bosnia and Herzegovina .
