Massive Solar Flare Could Knock Out The Power Grid In 12 Hours

http://bit.ly/1zfNXza In June, the sun seemed to have a tempter tantrum, releasing two solar flares towards Earth in a single week. Scientists are keeping a close eye on the sun’s weather cycle. A large enough solar flare could knock out power grids, plunging cities across the globe into darkness in as little as 12 hours. Solar flares are a common phenomenon that accompany the sun’s eleven-year cycle. Scientists monitor the solar cycle by noting the number of sun spots peppered across the sun’s equator. Solar flares usually form in the same region as sun spots; they occur whenever the sun belches a stream of charged particles from its surface. A coronal mass ejection occurs whenever an explosion on the surface of the sun causes some of its corona to detach. These can cause serious damage to satellites if directed towards Earth. The strongest observed coronal mass ejection to bombard the Earth occurred in 1859, which caused telegraph machines to spark and set flame.(2) Where there is violence in nature there is also beauty. Physicists characterize the plasma attached to a coronal mass ejection as a fourth state of matter which is responsible for the aurora borealis. The plasma is comprised of negative and positive charged particles. These particles peal apart when they come into contact with the Earth’s magnetic field, spiral down the poles and paint the sky different colors, from green to purple. This is why the aurora borealis is best seen in the North. http://bit.ly/1J6dVYw
