NASA | Solar Cycle

The video explains the dynamic nature of the sun, focusing on the sunspot cycle, which lasts about 11 years and affects solar activity. Sunspots indicate magnetic field activity, influencing solar flares and coronal mass ejections. The sunspot cycle is part of a longer 22-year solar cycle, where the sun's magnetic poles flip. Currently, the sun is nearing a solar maximum, with increased solar activity expected. Predictions about future cycles remain uncertain, but variations in sunspot activity are normal.
