Supernovas

A very large star explodes, somewhere in the unfathomable space of our galaxy. The star's core collapses. The monstrous pressure crushes its atoms and smashes their electrons into the nuclei. There, the negatively charged protons change to neutrons and neutrinos. Billions of neutrinos particles, that have no electrical charge and little or no mass, escape through the star's outer shell into space. Traveling at nearly the speed of light, they penetrate clouds, reach Earth, and pass harmlessly through the bodies of millions of people and everything else in their ways.
A Supernova such as this occurs about once every 30 years in any one galaxy. At some time in their long lives, the ...

nuclear energy. If the star is particularly massive, then its core will collapse and in so doing will release a huge amount of energy. This will cause a blast waver that ejects the stars envelope into interstellar space. The result of the collapse may be, in some cases, a rapidly rotating neutron start that can be observed many years later as a radio pulsar. As a result of gravitational forces acting against the nuclear structure of the core of a fuel depleted star, tremendous shock wavers are generated which cause the outside layers of the star to be blown away from the core. This can happen in one of two ways depending on the type of supernova.
There are two main type of supernovae Type I and Type II then others branch off of these. The Type I involves two stars. One star is a white dwarf whose gravitational attraction is so intense that it is capable of siphoning off material from its companion. Unfortunately for the star, the white dwarf exceeds its Chandrasekhar limit of ...
