A supernova is an extremely violent explosion of a star many times more
massive than our
Sun. During this explosion, the star may become as bright as all the other
stars in a galaxy combined, and in which a great deal of matter is thrown
off into space at high velocity and high energy. The remnant of these
massive stars collapse into either a neutron star or a black hole.
