Forget cicadas: the sun’s magnetic life cycle is where it’s at

The Independent UK has an article about the reversal of the sun’s magnetic field.  Every twenty-two years, the sun’s magnetic field reverses, with effects that reach to the end of our solar system:

Changes to the field’s polarity ripple all the way out to the Voyager probes, on the doorstep of interstellar space.”

NASA made a video of a simulation of the pole reversal:
