Check out these incredible photos and videos of a coronal mass ejection taken by the newly commissioned Solar Dynamics Observatory. The clarity and resolution of the images are absolutely stunning. When the CME erupts, you can clearly see the spiraling of the magnetic field lines as they spring up out of the surface of the sun, twist around until a filament breaks off, then collapse back into the surface. It gives you a really good intuitive feeling for the dynamics behind some events which are so important to us hams. I've embedded a YouTube version of the video below, but it's best if you go and download the full resolution versions from the website linked above to see them in their true glory.
