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 . star is a massive ball of plasma that emits . light and electromagnetic energy . throughout the universe. . While . there is only one star in our solar system, there are billions upon billions of stars throughout our galaxy and exponentially more in the billions of galaxies in the universe. 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. . Daisaku Nogami (Kyoto University). 2014/01/23(Thu). Subaru User's Meeting 2013@NAOJ.
