NASA releases incredible video of solar flare

Check out this astonishing video of a solar flare captured by NASA's Solar Dynamics Observatory.  Despite being only a medium-sized flare, these arcs of plasma cover a space many tines the size of the Earth.  Flares like this can have a real impact on our planet, too.  In addition to disrupting radio communications and threatening satellites, the streams of electrically-charged particles released during such events create the beautiful aurora.
