The Massive Solar Blast that Almost Wreaked Havoc on Earth

     Earth dodged one of the most massive magnetic solar bursts ever on July 23, 2012, scientists with the University of California, Berkeley revealed on Wednesday -- saving the planet from widespread havoc.

"Had it hit Earth, it probably would have been like the big one in 1859, but the effect today, with our modern technologies, would have been tremendous," UC Berkeley research physicist Janet G. Luhmann said in a press release.

According to researchers had the quick succession of coronal mass ejections, the most intense kind of solar eruptions, come nine days earlier, it would have hit Earth, potentially disabling satellites and GPS and the electrical grid.

A study from last year revealed that a solar storm like the one Earth narrowly avoided could have cost up to $2.6 trillion in damages. A similar event in March 1989 caused Canada's Hydro-Quebec power grid to collapse and left six million people with no electricity for nine hours.

"The cost of an extreme space weather event, if it hits Earth, could reach trillions of dollars with a potential recovery time of 4-10 years," professor at China's State Key Laboratory of Space Weather Ying D. Liu warned in a press release. "Therefore, it is paramount to the security and economic interest of the modern society to understand solar superstorms." . . .
