Stunning Image Captures Massive 'Plasma Waterfall' on Sun.

Astronomer Eduardo Poupeau captured a photo of a 100,000 kilometer-high 'plasma waterfall' rising from the surface of the sun. These polar crown prominences are common but not often photographed. Experts warn that if the plasma is blasted away from the sun and hits Earth it could end up knocking out the planet's electricity grid. In rare cases, magnetic forces can also become so strong that the hot plasma erupts away from the sun and into space — in what is called a coronal mass ejection (CME).
