I have upload blog entries with fantastic timelapse videos showing the polar Aurora effect. But i haven't upload any yet showing how this Aurora effect is generated. I suppose that more or less, everyone knows where it comes from. This video uploaded by space.com has an awesome animation to explain the origin of this wonderful phenomenon.
|Plasma from solar flares or coronal mass ejections travel along solar wind to ultimately produce aurora's in Earth's polar regions. This visually stunning explanatory video takes you on a journey from sun's interior to the Earth's upper atmosphere.|
