Every eleven years, the sun's magnetic field flips. Sunspots—dark, cooler regions on the sun's surface that mark intense ...

Something massive is happening beneath your feet right now, and most people have absolutely no idea. Earth's magnetic field, ...

Magnetic deposits laid down during the Ediacaran Period, 630 million years ago to 541 million years ago, are not inexplicable fluctuations, some researchers argue. Instead, there is a pattern encoded ...

The sun’s surface is a brilliant display of sunspots and flares driven by the solar magnetic field, which is internally generated through a process called dynamo action. Astrophysicists have assumed ...

Our Sun is far from a smooth, white ball in the sky. Twisting and looping magnetic field lines rise from its surface like hair, causing dark, transient patches on the surface called sunspots wherever ...

It's well established that the universe is expanding, but there's serious disagreement among scientists over how fast it's happening. Two of our best ways of measuring the cosmic expansion rate, the ...

Twisting atomically thin magnetic layers does more than reshape their electronics—it can create giant, topological magnetic textures. In chromium triiodide, researchers observed skyrmion-like patterns ...

Ofer Cohen works for the University of Massachusetts Lowell. The university benefits from any public article that is written by one of its faculty in terms of exposure and visibility. Ofer Cohen ...
