Having, as I do, an interest in matters astronomical, I subscribe to the NASA Science Newsletter (you can, too, by clicking here). Among the other extraterrestrial beats covered by their rovingest of reporters is the violent surface of our Sun.
The newsletter’s latest number carries a fantastic video of a swirling magnetic paroxysm, a vortex of nuclear fire nearly the size of the Earth. Read the story, and see the video, here.
