Imagine a waterfall made of hot plasma falling from a precipice tall enough to swallow Earth five times. Here it is:
Dutch photographer "Neo" captured this movie on August 28th. "For three days I've been watching these prominences around the edge of the active sun," he says. "The plasma did not stop falling for a moment."
Plasma falls have been seen on the sun many times before, yet researchers still don't fully understand them. One big mystery is how fast they fall. The sun's gravity is powerful, but not powerful enough to pull the plasma down so quickly through the thicket of solar magnetic fields.
Nuclear engineers would like to figure out how this happens, because it also happens on a smaller scale in fusion reactors, frustrating their efforts to sustain an energy-producing reaction. Studies of plasma falls on the sun could lead to practical breakthroughs here on Earth.
