Limb darkening. The surface of the sun does not have uniform brightness, it appears bright toward the centre, darker towards the edges, and the colour is redder, an effect known as Limb darkening - why?. a physical perspective . . 1. Philip Judge, . . High Altitude Observatory, NCAR. "Double, double, toil and trouble;. Fire burn, and cauldron bubble!". -- . Sunspots. – regions of strong magnetic activity. Sunspots are cooler than the rest of the photosphere and appear as dark splotches on the Sun. They seem to move across the Sun as the Sun rotates. The number of sunspots changes over time. They follow a cycle, peaking in number every 11 years. An average sunspot is about the size of Earth.. The story of sunspots. Dr. Lyndsay Fletcher, University of Glasgow. Image: Bill Leslie, Forres.

Sunspots and magnetic fields, the sunspot cycle. Solar activity and how it influences the Earth. CORE. The sun produces an enormous amount of energy in its core, or central region. The sun's energy comes from nuclear fusion. During nuclear fusion, hydrogen atoms join together to form helium. Nuclear fusion only can take place under conditions of extremely high pressure and temperature. The temperature inside the sun's core reaches 15 million C, high enough for nuclear fusion to take place. .
