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 sunspots are the visible evidence of the solar magnetic field changing its polarity, and appear as darker areas where there is a greater strength of magnetic flux in the sun’s photosphere.

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 ...

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 ...

These new observations showcase sunspots, granules, and magnetic fields with unprecedented clarity, revealing the processes that shape the Sun’s activity. By employing cutting-edge imaging ...

Helioseismic and Magnetic Imager (HMI) image of the big sunspot that occurred on 5 May 2024, in magnetic field. Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news ...

Such low-frequency radiation will escape from the sun in the presence of a steady magnetic field, like those found in sunspots.

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 ...

Another display of the northern lights could be visible this weekend in several U.S. states following a severe solar storm.
