As sunspots emerge on the sun's surface close to its equator, their orientations will match the old magnetic field, while sunspots forming closer to the poles will have a magnetic field matching the ...

A NASA satellite that suddenly reappeared after going silent gets credit for the remarkable discovery—a pair of temporary ...

The sunspot, named 3856, is facing Earth and has developed a volatile type of magnetic field known as a "beta-gamma-delta" ...

This magnetogram — a map of the sun's magnetic field — shows it's concentrated around sunspots on its surface. This strong magnetic field, indicated by red and blue areas, inhibits material ...

Satellites have managed to detect faint electromagnetic signals generated by ocean tides, suggesting that space-born sensors ...

Images captured by NASA's Solar Dynamics Observatory have revealed that "coronal loops" give off subtle flashes of ultraviolet light before a solar flare, which could act as an early warning system ...

On a hot and humid Florida night in late August 1859, the sky suddenly lit up. But it was not from fireflies or a fireswamp. Instead, it was the Northern Lights–or aurora borealis. The aurora is ...

The colorful northern lights may reveal themselves to a wide swath of Americans Friday night due to an impending solar storm forecast to reach Earth.

During this phase, sunspot activity increases ... rhythms of the sun and its complex relationship with Earth’s magnetic field. One of the key factors behind auroral activity is the Russell ...

Let's take a deep dive into the phenomenon of the sun's magnetic field reversal and investigate the effects it could have on Earth. Related: How a giant sunspot unleashed solar storms that spawned ...
