Supergiant stars of at least eight solar masses will explode as
Type II supernovas.
you would have a type II supernova
A supernova, or in the case of a smaller star, a nova.
Betelgeuse will be a Type II Supernova.
Supernovas [See Link] are classified according to the absorption lines of different chemical elements that appear in their spectra. The classification can be simplified to Type I or Type II Type II - If a supernova's spectrum contains a line of hydrogen in the visual portion of the spectrum. Type I - all the rest. These are broken down even further. Type:- Ia - When a white dwarf merges with another star. Ib & Ic are formed by massive stars running out of fuel but have lost the outer layer of hydrogen and helium like Wolf-Rayet stars Type II are the "normal" types of supernova, where massive stars can no longer maintain hydrostatic equilibrium and the core collapses IIP Reaches a "plateau" in its light curve IIL Displays a "linear" decrease in its light curve Supernova [See Link] classifications are based on chemical composition.
When a blue star blows up t is called a supernova, which eventually leads into the formation of a black hole. Although a regular star, say our sun, doesn't blow up, it turns into a huge super giant, it grows 5X its normal size and it will either gulp earth up, or burn us to death, but don't worry, that won't happen for a couple billion years, but not so good for your Great Great Great Great Great Great Great Great Great [could go forever] grand children :D

It will end its life as a type II supernova.
Betelgeuse will be a Type II Supernova.
A lot of mass. Generally for a type II supernova more that 9 solar masses. See related question.

Type II supernova. Formation of a neutron star or black hole.
Stars with a mass about 9 solar masses, or greater, will explode as a type II supernova.

A red super giant star nearing the end of its life. It is currently fusing helium in its core. Betelgeuse is expected to explode as a type II supernova, possibly within the next million years.
A star made almost entirely of neutrons that has expelled all other matter. Formed as a type II, Ib, or Ic supernova remnant with too little stellar material to form a black hole.
The last phase will be a type II supernova explosions.
