Discovery of fastest ever magnetic wave propagation

Like light waves, magnetic waves move through materials at a fixed maximum velocity. However, at the smallest possible length scale (nanometres) and the shortest possible time scale (femtoseconds), magnetism behaves differently. ...

NASA model describes nearby star that resembles early sun

New research led by NASA provides a closer look at a nearby star thought to resemble our young sun. The work allows scientists to better understand what our sun may have been like when it was young, and how it may have shaped ...

Unravelling the knotty problem of the sun's activity

A new approach to analyzing the development of magnetic tangles on the Sun has led to a breakthrough in a longstanding debate about how solar energy is injected into the solar atmosphere before being released into space, ...

The origin of bifurcated current sheets explained

A Korean research team has identified the origin of bifurcated current sheets, considered one of the most unsolved mysteries in the Earth's magnetosphere and in magnetized plasma physics.

Shaken, not stirred: Ultrafast skyrmion reshuffling

Smaller, faster, more energy-efficient: future requirements to computing and data storage are hard to fulfill and alternative concepts are continuously explored. Small magnetic textures, so-called skyrmions, may become an ...
