The Sun turns, but not in the way a solid object would. It has no hard surface, no fixed edge to follow. What scientists ...

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 ...

Composite video image from NASA’s Solar Dynamics Observatory and NOAA’s Geostationary Operational Environmental Satellite – R Series Solar Ultraviolet Imager instrument shows small-scale jetlet ...

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 ...

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 ...
