A supernova occurs when a high mass star dies and becomes a neutron star. As the core collapses because fusion burns out and radiation pressure can no longer hold it up, then degenerate electron pressure can not hold it up, the electrons are forced into the nucleus and combine with protons to form neutrons, the strong force causes the nuclei to merge into one ball of neutrons: a neutron star. The surface of the neutron star is very hard and as additional matter from the original star continues to fall in and merge into the neutron star, a "traffic jam" occurs and the shockwave resulting from this reflects off the super hard surface of the neutron star, driving the supernova explosion. Suddenly everything falling in is now rushing out. This can only occur once.
What else can I help you with?
When a very large star explodes it is called a?
supernova
What is produced when the outer core of the star explodes after the core collapses?
Supernova
What is produced when the outer core of star explodes after the core collapses?
Supernova
What happens when a single high mass star explodes?
When a single high mass star explodes, it undergoes a supernova event. The core collapses inwards and then rebounds explosively, sending out a shockwave that ejects the outer layers of the star into space. This explosion can outshine an entire galaxy for a short period of time.
When a high-mass star turns into a super-giant and then explodes the explosion is called?
A Nova or a Supernova.
What is a dying star that explodes?
a supernova
When a very large star explodes it is called a?
supernova
What science term describes when a star explodes?
A supernova.
What might happened to a star after it explodes as a supernova?
The supernova remnant will either be a neutron star or a black hole.
What is a star that explodes and throw off a bright outer shell of gas called?
A star that explodes is called a supernova.
Where is nitrogen and iron formed in the big bang?
The heavy elements are formed when a supernova explodes. That happens quite frequently, when a star suddenly increases in brightness by a huge amount for a few months. If a supernova is close to us it can be seen as a new star, and that happens about twice in 1000 years.

What happens with the white dwarf in a type 1a supernova?
The white dwarf collapses under its own gravity. This starts very rapid nuclear fusion reactions. It explodes as a supernova and "stuff" is scattered into space. Essentially nothing of the white dwarf, as an object, remains.
What is a star called right before it explodes?
Normally it is known as the supernova's progenitor star.
