Currently, there is no real way of knowing when a star will go supernova within a few thousand to million years.
There are signs, that a star will go supernova based on physics and observations but WHEN is a problem.
A star will "pulse" in a "last breath" prior to going supernova, but like death itself, no one really knows, when that last breath will happen.
Betelgeuse, is experiencing those "last breaths" but when it will happen, or has happened, we will not know until we see the brilleint outburst from Earth.
Never. A star must be about 10 times the mass of the sun or more to go supernova.
well what you gotta do is go home a smoke weed
A star will become a supernova only once.However, a white dwarf can have multiple novaeruptions.See related questions
Rock Star Supernova was created in 2006.
No. A neutron star is left behind after a supernova. However, some gamma ray bursts may result from a collision between neutron stars.
No, only large stars go supernova when nuclear fusion breaks down. While white dwarfs can go supernova in some instances, brown dwarfs are failed stars which are not powered by nuclear fusion.
There are currently no stars in the Orion constellation showing signs of going supernova. If a star in the Orion constellation were to go supernova, it would likely be visible to us on Earth given Orion's proximity.
A supernova occurs at the end of a massive star's life cycle.

It's Called A Supernova
A supernova is a star that has exploded into dust and gas. A white-dwarf is a small, hot, dense star nearing the end of its life, that did not have enough mass to go supernova. So the answer is "none".
Under certain conditions, a large star can go supernova, and blast itself to smithereens. Our star (Sol, or Sun) cannot go supernova unless it would somehow 'capture' a white dwarf. This would be billions of years from now, so don't worry.
