But why?
The Sun is set to “flip upside down” within weeks as its magnetic field reverses polarity in an event that will send ripple effects throughout the solar system.

Although it may sound like a catastrophic occurrence, there’s no need to run for cover. The sun switches its polarity, flipping its magnetic north and south, once every eleven years through an internal mechanism about which little is understood.

The swap could however cause intergalactic weather fronts such as geomagnetic storms, which can interfere with satellites and cause radio blackouts.
