New satellite data show Earth’s magnetic field changing fast, with a growing weak spot over the South Atlantic.

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects ...

Using 11 years of magnetic field measurements from the European Space Agency's Swarm satellite constellation, scientists have ...

New research led by Southwest Research Institute (SwRI) has confirmed decades-old theoretical models of magnetic reconnection, the process that releases stored magnetic energy to drive solar flares, ...

Astronomers have developed a groundbreaking computer simulation to explore, in unprecedented detail, magnetism and turbulence in the interstellar medium (ISM) -- the vast ocean of gas and charged ...

No one has ever probed a particle more stringently than this. In a new experiment, scientists measured a magnetic property of the electron more carefully than ever before, making the most precise ...

Sustained radio emissions originating from high over a sunspot are getting researchers thinking in new directions. Unlike solar radio bursts — which typically last only minutes or hours — these have ...

In the late 1980s, scientists realized they could understand the interior properties of the sun by observing the sound waves that resonate inside it. This technique, called helioseismology, revealed a ...
