Astrophysicists have pinpointed the origins of the sun’s magnetic field much closer to its surface than previously thought. This revelation could alter our understanding of solar activity and improve predictions of potentially disruptive solar storms, the most powerful of which could be so strong they could knock out power grids and even the entire internet. For decades, astronomers believed that the sun’s magnetic field was generated deep within its core. That’s certainly the way it works for Earth’s magnetic field, which is produced by the motion of molten iron inside our planet’s core, like…
