Sunspots are temporary, dark regions on the sun's surface caused by concentrated magnetic activity, which inhibits the flow of hot plasma and lowers their temperature compared to the surrounding ...
During this active phase, the sun's magnetic field eventually snaps and completely flips, which triggers a falling-off period of solar activity and a decrease in sunspots until the whole cycle ...
The solar cycle refers to the 11-year period of solar activity from a maximum of observed sunspots through a minimum to a new maximum. The sunspots are the visible evidence of the solar magnetic ...
The sun's magnetic activity—the origin of the solar wind and the resulting bright aurora displays—is calculated daily by counting sunspots on its surface. Sunspots are magnetic disturbances on ...
The Sun's impressive collection of sunspots implies that its period of peak activity, which likely began earlier this year, will be even livelier than originally thought. Having begun in December ...
CMEs are enormous clouds of solar plasma and solar magnetic field that are spat out of our star during periods of intense activity. CMEs are usually produced at sunspot regions and often accompany ...
