A team of astronomers has created the first-ever map of magnetic field structures within a spiral arm of our Milky Way galaxy. Previous studies on galactic magnetic fields only gave a very general ...

Magnetic fields play an important—if sometimes underappreciated—part in planetary systems. Without a strong magnetic field, planets can end up as a barren wasteland like Mars, or they could indirectly ...

Earth's magnetic field is weakening and its north pole is shifting faster than previously observed, raising concerns about a potential geomagnetic reversal. Geomagnetic reversals, where the magnetic ...
