What causes supernova explosions?

What causes supernova explosions?

Supernova explosions are caused by the rapid collapse of a massive star's core or the accumulation of material on a white dwarf.

Can you explain the difference between a Type I and Type II supernova?

Type I supernovae occur in binary systems where a white dwarf accumulates matter, while Type II supernovae result from the core collapse of massive stars.

What happens to the star after a supernova?

After a supernova, the core may become a neutron star or black hole, while the outer layers are expelled into space, enriching the interstellar medium.

How often do supernovae occur in our galaxy?

Supernovae occur in our galaxy approximately once every 50 years, but many may go unnoticed due to their distance.

What role do supernovae play in the universe?

Supernovae play a crucial role in the universe by dispersing heavy elements, contributing to the formation of new stars and planets.
