The Solar System is about to feel the force of the Sun's power when its magnetic field "flips" in the next few weeks.
The Sun switches its polarity, its magnetic north and south, once every 11 years.
Professor Tim O'Brien, an astrophysicist from the University of Manchester's Jodrell Bank Observatory, explained the phenomenon.
