We cover the Earth and Sun’s scheduled pole shifts. Usually the Sun's enormous magnetic field's north pole becomes south, and vice versa, every 11 years, and we are now entering solar cycle number 25. But the recent sunspot cycle has been weirdly drawn out. All this activity has its roots far below the surface in a solar zone called the tachocline, about 70% of the way from the center toward its gassy surface. It's powerful and yet, most people are more concerned about Earth's magnetic poles flipping over. Could our poles shift too?
