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 ...

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 ...

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.

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

The Origin of the Sun's Magnetic Field Could Lie Close to Its Surface May 22, 2024 — Surprise findings suggest sunspots and solar flares could be generated by a magnetic field within the Sun's ...

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 ...
