WASHINGTON (Reuters) - The solar wind, which whips off the sun and blows past Earth and through the solar system, is unleashed by powerful magnetic waves in electrically charged gas around the sun, scientists said on Thursday. The mechanisms that cause the solar wind had baffled scientists for decades, but were revealed in observations by a Japanese satellite called Hinode orbiting Earth, the scientists said in research published in the journal Science. "The magnificent thing about the success of Hinode is its unprecedented view of the dynamics of the sun," Jonathan Cirtain, a solar physicist at NASA's Marshall Space Flight...
