Super Nova

super nova

A super nova is an exploding star. In lower mass cores the collapse is stopped and the newly formed neutron core has an initial temperature of about 100 billion kelvin, 6000 times the temperature of the sun's core.On average, a supernova will occur about once every 50 years in a galaxy the size of the Milky Way. Put another way, a star explodes every second or so somewhere in the universe, and some of those aren't too far from Earth.Iron atoms become crushed so closely together that the repulsive forces of their nuclei create a recoil of the squeezed core a bounce that causes the star to explode as a supernova and give birth to an enormous, super heated, shock wave. Supernovae also occur in binary star systems.Since a supernova explosion can occur whenever the mass of the star at the time of core collapse is low enough not to cause complete fallback to a black hole, any massive star may result in a supernova if it loses enough mass before core collapse occur.
