Are there any storms on the sun?
Sunspots may be called "storms on the sun" : the magnetic flow within a sunspot causes disruptions to the transfer of energy to the sun's surface from the interior. The result is a region much less bright than the normal surface (but 'dark' only when viewed through special filters - one cannot see sunspots with the naked eye). ---On the other hand, the Sun is nothing but one big storm of energy created by nuclear fusion! This process roils and boils the atoms in the sun with such intensity that it's surface temperature is nearly 11,000°F (6,100°C). Hot as the solar surface is, deep inside the sun's core, the high rate of energy generation and the intense pressure(some 5 million pounds per square inch) heats the gas to nearly 27 million°F (15 million°C). The process that fuels the sun is the ceaseless fusion of hydrogen into helium. This in turn releases energy in the form of gamma rays that bounce from one atom to another until, after a million years or so, the energy finally reaches the sun's surface and is released in the form of visible light and heat. Every second, the sun releases as much energy as 90 billion one-megaton hydrogen bombs. All this tremendous unimaginable action causes absolutely massive Magnetic Fields to be generated. These can cause "Solar Flares" that expel enormous amounts of highly energetic gas. When these magnetic fields collapse, radiation is emitted across virtually the entire electromagnetic spectrum. Our Sun is an average star and is about 40 percent along in its expected 12-billion-year lifespan. About 6 billion years from now, it will have used up its hydrogen fuel and begin fusing its helium nuclei. As a result, the sun will swell into a red giant, so huge that it may encompass the Earth's orbit. After another billion years the red giant will eject its outer layers, leaving only a small white dwarf star that will cool and fade away.
