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 ...

How the universe got its large magnetic fields has remained one of the stickiest outstanding problems in astrophysics. Now, researchers have proposed a novel solution: a giant "dust battery" operating ...

Long before galaxies sparkled in the sky or stars took shape, invisible forces stirred in the early Universe. One of those forces—magnetism—emerged in ways scientists are only now beginning to ...
