Video of magnetic field lines 'slipping reconnection' bring scientists a step closer to predicting when and where large flares will occur.

Space Weather Shielding Provided By Plasma Plumes
2014-03-07 05:41:48

The magnetosphere, Earth's magnetic field, stretches from the core of the planet out into space. Here, the magnetosphere meets the solar wind, a stream of charged particles emitted by the sun. The magnetosphere, for the main part, acts to shield the Earth from this high-energy solar activity.
