Most solar explosion in five years took place yesterday, launching into space a cloud phenomenon ten billion tons with a speed of over eight million miles per hour.

Scientists said the explosion occurred on the Sun that is not directed towards Earth, so it will not impact on satellites and communications systems, reports dailymail.co.uk.

Joe Kunches Space Weather Prediction Center in Colorado said that the explosion effects were only small breaks in radio emissions in Asia.

"I was lucky because the place was not the eruption of the Sun facing Earth, so we feel prpbabil side effects," said the expert.

The image was captured by NASA's Solar Observatory. Researchers estimate that over the next three to five years there will be many such explosions. The last time there was an explosion so powerful it was in December 2006.

Scientists have warned that solar flares could be devastating for human technology over approximately two years, when they peak.

Kathryn Sullivan, secretary at the U.S. Oceanic and Atmospheric Administration, said the storms are an increasing threat to satellite communications, navigation systems and power transmission equipment. Solar storms that can temporarily disable particles released or destroy computer circuits.

A powerful solar storm could cause damage the U.S. economy 20 times larger than those caused by Hurricane Katrina in 2005, American Academy of Sciences warned in a report published in 2008. The cost of these losses could reach two trillion dollars in the first year after such a catastrophe.

This report revealed for the first time the vulnerability of key sectors: electricity networks, GPS tracking system, air transport, financial transactions and communications by radio.

On March 13, 1989, a magnetic storm caused by a stream of solar particles loaded with electric charge caused a breakdown of the Hydro-Quebec network, depriving of over 6 million Canadian electricity for nine hours.

In 2003, a magnetic storm caused the destruction of transformers in South Africa, electricity depriving much of the population of this country. And North America has been seriously affected by that storm.

In 1921, a magnetic storm caused a number of currents in the ground 10 times stronger than those recorded in 1989 in Quebec.
