Solar magnetism is a fundamental driver of dynamic phenomena on the Sun, manifesting in cyclic variations such as sunspot activity, flares, and coronal mass ejections. Central to this process is the ...

Images of the sun over 10 years reveal how the star's activity spikes and dips over time. (Credit: The Yohkoh mission of ISAS, Japan, and NASA, United States) A team of solar scientists have uncovered ...

Scientists studying sound waves from deep inside the Sun have provided new insights into the solar dynamo within, which could help to explain how the Sun’s colossal magnetic field behaves. An ...

The cover article in the scientific journal Nature published today — co-authored by Bates Associate Professor of Physics Jeffrey Oishi — upends decades-old beliefs about the sun and solar phenomena ...

The Sun’s activity is determined by the Sun’s magnetic field. Two combined effects are responsible for the latter: The omega and the alpha effect. Exactly where and how the alpha effect originates is ...

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 ...

"We show that isolated perturbations near the sun's surface, far from the deeper layers, can grow over time to potentially produce the magnetic structures we see." When you purchase through links on ...

Researchers have discovered a new relationship between the Sun's magnetic field and its sunspot cycle, that can help predict when the peak in solar activity will occur. Their work indicates that the ...

A team of solar scientists have uncovered the possible originals of the engine that drives much of the sun’s volatile nature—generating the sunspots that move like storm clouds over the surface and ...

In 1612, astronomer Galileo Galilei observed dark splotches can sunspots moving across the face of the sun. A new study could reveal the engine that drives these cloudy features, and much of the sun's ...
