The sun is having an identity crisis: Because it shows different magnetic activity and rotation rates than other stars in its current classification, scientists have debated whether the sun is really ...

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 ...

New research identifies how two vast, hot rock structures in the planet’s mantle produce unusual magnetic activity.

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 ...

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 ...
