Every eleven years, the sun's magnetic field flips. Sunspots—dark, cooler regions on the sun's surface that mark intense ...

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 study published in Nature Astronomy, led by Dr. Jie Yu, from the Australian National University, reveals that stars in close binary systems—pairs of stars orbiting each other at close range—can ...

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 is read by an automated voice. Please report any issues or inconsistencies here. Apollo rocks show the moon’s magnetic field experienced intense spikes 3 billion to 4 billion years ago that ...

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 ...
