Super+Nova

//**SUPER NOVA **//

==A supernova is simply a stellar explosion. Supernovas are extremely luminous and cause a burst of radiation. During this short interval, a supernova can radiate as much energy as the sun could emit over its life span. The explosion expels much or all of a star's material at a velocity of up to a tenth the speed of light, driving a shockwave into the surrounding interstellar medium. This shock wave sweeps up an expanding shell of gas and dust called a "supernova rement". Several kinds of supernovae exist that may be triggered in one of two ways, either turning off or suddenly turning on the production of energy through nuclear fusion. On average, supernovae occur about once every 50 years in a galaxy the size of the Milky Way. Supernovae in other galaxies cannot be predicted with any meaningful accuracy. Normally, when they are discovered, they are already in progress. == = = = = =__Habitability: __= ==The is no chance for any life form to live on a supernova since its just a ticking time bomb ready to explode but if you like to blow up this is "__**pa**__ __**ra**__ **__dice__**". ==

= Fun Facts: = = v A supernova is the final, gigantic explosion of a supergiant star at the end of its life. = = v A supernova lasts for just a week or so, but shines as bright as a galaxy of 100 billion ordinary stars. = == v A supernova can beam out enough light to last a lifetime.  ==
