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 ...

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