As black holes feed, they pull material into a disk around them. The material orbiting in this disk gets heated to extreme temperatures, and so it becomes a plasma — a state of matter in which some of ...

Materials with magnetic nanostructures have a wide range of potential applications. One area is so-called spintronics, with ...

The largest magnetic map of the universe ever produced—five times larger than all previous efforts combined—marks the beginning of a new generation of research into intergalactic magnetism. Magnetic ...

Magnetic micro-flowers concentrate applied magnetic fields around samples, allowing high-field nanoscale imaging and ...

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 ...

Deep inside the Milky Way, an invisible force is quietly holding everything together — its magnetic field. Now, researchers have created one of the most detailed maps ever of this hidden structure, ...
