The SUN was formed from a globe of hydrogen and helium gas under high temperature and pressure.Thermonuclear reaction inside the sun created from the high temperature and pressure, convert's hydrogen to helium releasing enormous energy forming the layer's of hot gases that make up the sun.On the outer layer of the sun,violent storm's,nuclear eruption's and solar flare's send hot hydrogen gas hundred's of thousand's of mile's into the outer atmosphere,arching back to the sun's exploding nuclear surface.The thin outer atmosphere of the sun, reaches temperature's of a million degree's.About every 11.5 year's,the sun goes thur a cycle that changes the shape of the outer atmosphere.This change causes greater solar flare activity.Electrical and communication's system's on Earth are affected by this cycle of the sun.

The sun is 5 billion year's old,stable,and will remain that way for another several billion year's.At that time,the sun will have used most of it's energy and start to expand outward into the solar system.Mecury and venus will be absorbed by the sun.The Earth's ice cap's will melt raising the level of the ocean's,flooding most of the Earth's landmass.The ocean's will evaporate,Earth's atmosphere will be lost to space leaving Earth barren and desolate.Or perhap's "this red giant" will expand to the orbit Earth. Several thousand year's after,the sun will begin to palsate every millinium or so,and with the sun's last dieing palse a thin layer of hot hydrogen gas,thrown off by the sun, will form an exspanding sphere around the solar system(of rock's and ice).As the hydrogen sphere expand's,the sun will collapse in on it's self forming a small white star,about the size of the planet Earth.
