A lot of mass. Generally for a type II supernova more that 9 solar masses.

Never. A star must be about 10 times the mass of the sun or more to go supernova.
Rock Star Supernova was created in 2006.
A supernova occurs at the end of a massive star's life cycle.

It's Called A Supernova
A supernova, or in the case of a smaller star, a nova.
The supernova remnant will either be a neutron star or a black hole.
Dangerous. Novas, or supernovas. Tycho Brahe coined the phrase "nova stellarum" when a "new star" appeared in the night sky. We now know that he was observing a supernova, the death throes of a very massive star.
Well, a star must die eventually! Everything in the universe will be destroyed, or will just die. No matter what.
A star must have at least 8 times the mass of the Sun in order to undergo a supernova explosion at the end of its life cycle. This is because stars need to have enough mass to generate the tremendous pressure and temperature required for a supernova to occur.
No, not a supernova.
