Lightning 101 Video
Learn about the forces that cause lightning. It is generally thought that lightening often occurs within the downdrafts and updrafts of thunderstorms.  Lighter particals moving towards the top of the cloud become positively charged while heavier particles heading towards the bottom become negatively charged.  When positive and negative charges grow large enough, lightening is released.   Run time 02:38.

Catching Solar Waves
Kelvin-Helmholtz instabilities occur when two fluids of different densities or different speeds flow by each other. In the case of ocean waves, that's the dense water and the lighter air. As they flow past each other, slight ripples can be quickly amplified into the giant waves loved by surfers. In the case of the solar atmosphere, which is made of a very hot and electrically charged gas called plasma, the two flows come from an expanse of plasma erupting off the sun's surface as it passes by pl
