The name of the explosion that happens when a massive star dies is called a supernova (-novae, plural). Some stars that have an unusually energetic explosion or are extremely large stars that are subclassified as hypernova (-novae plual).
The reason this explosion only occurs with massive stars (At least 20 solar masses) is because larger stars, when they start to run out of fuel, begin fusing much heavier elements than the smaller star is capable of. The difference between the two is a white dwarf and a neutron star or gravitational singularity.
A star's core is extremely dense, so dense that the only way for a star to counterbalance it's own gravitational pull from collapsing the star into itself is to fuse helium. The star uses the helium to create pressure that causes enough outward pressure on the star that it balances out the star's own gravity.
When a large star is running out of fuel, it starts to collapse. However, this collapse causes the star to become hot enough to fuse the helium that built up in the core when it was young into carbon and oxygen. Once it starts running out of helium, it collapses a little bit again but now hot enough to fuse the carbon in the core into neon, then the neon into more oxygen and, then the oxygen into silicon and finally silicon into nickel which decays into iron. At this point the star is dead, the only thing preventing total collapse is electron degeneracy. If the star's Fe-Ni core is small, under 1.4 solar masses, it will be just a dead star that's hot enough to emit light and solar winds will blow away it's "atmosphere," forming a planetary nebula. This phase is called the red giant.
If the Fe-Ni core is over 1.4 solar masses, it will be too dense and collapses into itself. This collapse happens extremely quickly and when it's a few hundred kilometers in radius, it stops shrinking instantly due to electron degeneracy and all the matter it was taking with it is shot back like a shockwave, That is a supernova. Even denser results in a gravitational singularity with a large accretion disc of the star's remnant matter.
its called a super nova.
Short, violent, and ends as a black hole.
Massive stars, typically around eight times the mass of our sun, will end their life in a supernova explosion. During the explosion, the outer layers of the star are expelled into space, leaving behind a dense core known as a neutron star or black hole.
Massive stars that are at least eight times more massive than the Sun end their life as a supernova. During the explosion, these stars release a tremendous amount of energy and can briefly outshine an entire galaxy.
Red stars, like red giants or red supergiants, can undergo a massive explosion called a supernova when they reach the end of their life cycle. This explosion releases an immense amount of energy and creates heavy elements that are then scattered into space.
its called a super nova.
Yes, a supernova can form a new nebula. When a massive star ends its life in a supernova explosion, the explosion can create shockwaves that compress surrounding gas and dust, triggering the formation of a new nebula. This new nebula can eventually give birth to new stars and planetary systems.

The big bang, a massive explosion creating all life as we know it.
Massive stars, typically around eight times the mass of our sun, will end their life in a supernova explosion. During the explosion, the outer layers of the star are expelled into space, leaving behind a dense core known as a neutron star or black hole.
Massive stars that are at least eight times more massive than the Sun end their life as a supernova. During the explosion, these stars release a tremendous amount of energy and can briefly outshine an entire galaxy.
Less massive stars end up as white dwarfs. More massive stars end up as a supernova or a neutron star or for the really massive stars...as a black hole. As a star ends its time in the main sequence it either becomes a Red Giant and end its life as a White Dwarf or becomes a White Super Giant and ends its life in an explosion (supernova) and if it's really dense it becomes a neutron star or a black hole as mentioned above.
The stage missing in the chart is the supernova explosion. When a star ten times more massive than the sun reaches the end of its life cycle, it undergoes a supernova explosion, where the star's core collapses and then rebounds outward in a powerful explosion, leaving behind either a neutron star or a black hole.
The most massive stars will end up as black holes. Those are the stars that have more than approximately 3 solar masses at the end of their life - i.e., AFTER the supernova explosion.
nuclear fusion in a massive star that ended its life in a supernova explosion.
A star that is 1000 times as massive as the Sun will likely end its life in a supernova explosion, leaving either a neutron star or a black hole as a remnant, depending on the mass of the core after the explosion.
Total destruction and major air pollution which resulted in loss of life(nature and human beings)
