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 ...

Although we know the sun's age from independent measurements, the findings predict trouble ahead for similar studies of other stars. When you purchase through links on our site, we may earn an ...

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 ...

A century of solar observations from Kodaikanal Solar Observatory and modern satellite data reveal patterns in the Sun’s polar magnetic activity, aiding predictions of future solar cycles.
