Scientist FEAR HyperActive SUN - Solar Wind intensification years ahead
"I believe we're on the threshold of a new era in which space weather can be as influential in our daily lives as ordinary terrestrial weather," Fisher said.

It is not however known how the life on earth will take the full force of intensified solar activities due to the Sun's 'erratic' behavior.

Scientists have expressed concerns about an imminent period of intensified solar activities that is expected to wreak havoc on communication and power systems on Earth.

"The sun is waking up from a deep slumber, and in the next few years we expect to see much higher levels of solar activity," Head of NASA's Heliophysics Division Richard Fisher was quoted by space and astronomy news website SPACE.com as saying.

According to another official at NASA, Lika Guhathakurta, the magnetic field on the sun is expected to get twisted and tense as a result of which powerful electric charges will be sent rocketing toward earth.

The announcement comes as the US National Academy of Sciences issued a report in 2008, saying a major solar flare could cause damages in excess of $2 trillion -- 20 times costlier than Hurricane Katrina.

Threats such as sun storms have prompted scientists to develop space weather forecast systems in order to warn of incoming dangers targeting the Earth.

"I believe we're on the threshold of a new era in which space weather can be as influential in our daily lives as ordinary terrestrial weather," Fisher said.

Scientists say solar storms may soon impact humans' daily lives as the next sunspot cycle heralding increased solar eruptions draws near.

They fear that a peak in the solar flares, projected to take place in 2013 at the height of the Sun's magnetic activities, could potentially affect power grids, flights, telecommunications, radios and televisions.

The solar storms are also a source of concerns for air passengers traveling long distances as they could be exposed to enhanced radiation.

Scientists say over 900 operating satellites in space, worth an estimated $200 billion, could take the brunt of the Sun's eruptions.

It is not however known how the life on earth will take the full force of intensified solar activities due to the Sun's 'erratic' behavior.

The Sun undergoes an almost 11-year period of magnetic activities during which dark spots appear on its surface from where it spews matter and energy into space.

However, it has been behaving inconsistently over the past years, scientists say.
