A supernova is the catastrophic death of a star, characterized by a massive output of energy.
we all die
It is yes
If it's a big enough explosion it will become a supernova
they produce thermal energy
Your question does not make sense. A supernova does not die. A supernova is what happens when a supergiant or a hypergiant star becomes unstable and cannot maintain stability and explodes cutting away half of it's mass. I hope this helps you.
It's gamma rays will have traveled one light year.
A supernova occurs.
A supernova occurs.
you would have a type II supernova
Mass decides a stars ultimate fate.
It will explode as a type Ia supernova.
A supernova happens when most of the core of the collapsing star has become neutrons, held up against gravity by neutron degeneracy pressure. At this point a shockwave reflects from the neutron star surface, driving the supernova explosion.So the answer to your question is neutrons.
