The Sun’s magnetic poles are in the middle of an uneven, drawn-out reversal as Solar Cycle 25 moves through its solar maximum phase. NASA and NOAA jointly announced that the current cycle has entered ...

Solar magnetic activity plays a pivotal role in driving a myriad of eruptive events in the corona, including flares, filament eruptions and coronal mass ejections. These phenomena arise from the ...

A new model that posits the same physical process is responsible for magnetic field and the rotation patterns, contradicting previous theories that the sun’s magnetic field originates deep inside its ...

For the first time, scientists have used satellite data to create a 3D map of the sun's interior magnetic field, the fundamental driver of solar activity. The research, published in The Astrophysical ...

With insufficient modern data to predict activity, scientists were looking for ways to unlock the secrets of solar magnetism hidden in more than a century of KoSO data. The chromosphere just above the ...

A new model contradicts previous theories that the sun's magnetic field originates deep inside its interior. Deep origin theories could not explain rotation patterns of the sun's gas near its surface ...

This illustration lays a depiction of the sun's magnetic fields over an image captured by NASA’s Solar Dynamics Observatory. The complex overlay of lines can teach scientists about the ways the sun's ...
