Either somebody shoots at the star. Or kills the star turning it into a supernova.
A type-I supernova occurs when a white dwarf star accumulates mass from a companion star until it reaches a critical threshold, triggering a runaway nuclear fusion reaction. This causes the white dwarf to explode in a bright supernova event.
The onset of iron fusion causes a star to become a supernova. This process occurs when the star's core collapses due to the inability to support the fusion of iron, leading to a catastrophic explosion.
A star 8 times the mass of the sun will most likely explode in a supernova.
A supernova reaction occurs in the life cycle of a massive star that has exhausted its nuclear fuel and reaches the end of its life. The core of the star collapses under gravity, causing a powerful explosion that briefly outshines an entire galaxy.
Massive stars. See related question: 2nd Answer: Yes, massive stars, but ones with another star like a red giant orbiting each other. The to-be supernova 'sucks' material from the other star near it until its mass is large enough to make the star collapse and burst.
Supernova.

A supergiant star can explode into a supernova, where the outer layers are ejected into space. What remains may collapse into a neutron star or black hole, depending on the mass of the original star.
when a star is at the end of its life(depending on mass) a star will sponaniously explode into a supernova. or it will collapse into a black hole.
It will probably explode as a supernova, leaving either a neutron star or black hole.
A supernova comes to existence when a white dwarf drains the matter from any companion star up to a point in wich it cannot carry anymore, and then it will first implode, and afterwards it will explode, a supernova.
The onset of iron fusion causes a star to become a supernova. This process occurs when the star's core collapses due to the inability to support the fusion of iron, leading to a catastrophic explosion.
When a star explodes, it releases an immense amount of energy, creating a supernova. This explosion can outshine an entire galaxy for a short period of time. Supernovae are crucial for the formation of heavy elements and can also cause the star to collapse and form a black hole or neutron star.

The biggest star - VY Canis Majoris IS in a red supergiant phase and will explode as a massive supernova.
A supernova, resulting in either a neutron star or black hole. Also may heavy elements are blown out of the star during the explosion.
A star 8 times the mass of the sun will most likely explode in a supernova.
