How does the Earth generate its magnetic field? While the basic mechanisms seem to be understood, many details remain unresolved. A team of researchers from the Center for Advanced Systems ...

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects of viscosity in their simulation, they revealed a self-sustaining dynamo ...

Magnetic fields thread through galaxy clusters and stretch along cosmic filaments spanning hundreds of millions of light-years. They deflect cosmic rays, shape star formation, and influence the ...

The magnetic fields lacing through galaxy clusters and cosmic filaments have no business being there. The early universe was a hot, smooth soup of particles with no mechanism to spin up the enormous ...
