The Powerhouse Sun: Surface activity of the sun

The video explains the sun's massive size and its role in the solar system, comprising 99.8% of its mass. It describes the photosphere, a thin shell of gas that emits sunlight, and the dynamic processes within it, such as bubbling granules. Sunspots, cooler regions caused by magnetic fields, are discussed, along with their temperature differences. The solar cycle, an 11-year process involving magnetic field reversals, is explained, highlighting the sun's differential rotation. The video also covers the chromosphere, where solar prominences occur, driven by magnetic forces.
