Surprising differences in the two so-called Large Low-Velocity Provinces may risk instability in Earth's protective magnetic field.

Such extreme fluctuations are known to be caused by a combination of mechanisms taking place within the geomagnetic field, but the exact mechanism by which electrons are accelerated from energies ...

[Dr. Fortin] teaches physics at a French High School, and to get his students interested in the natural world around them, he built a geomagnetic observatory, able to tell his students if they ...

Magnetic pole shifts, a subject shrouded in both fascination and fear, refer to the movement of Earth's magnetic north and south poles. Unlike the geographic poles, which are fixed, magnetic poles ...

The Sun periodically ejects huge bubbles of plasma from its surface that contain an intense magnetic field. These events are called coronal mass ejections, or CMEs. When two of these ejections collide ...

Magnetotactic bacteria synthesize magnetic iron nanominerals, which function as tiny compasses that allow the microbes to navigate using Earth's geomagnetic field. Earth's iron cycle is a very ...

Geomagnetic storms are likely for March 25-26 this week, increasing the possibility of northern lights across the northern regions of the U.S. and parts of the Midwest. The sun has been active ...
