What is a Supernova? Pt.II

Now what makes the supernova explode, well strangely enough, it is not that well understood Though it is known that neutrinos are a major particle that plays a role in the super nova explosion. Though incidentally neutrinos don’t interact with matter or anything physical, almost behaving as a massless particle free-Roaming the universe. But a major percentage of the explosion is from neutrinos escaping to the surface of the dying star and then causes a massive explosion pushing all the out remnants of the dead star, flinging across the cosmos. Though the parts that get shot across space from the explosion is actually a small percentage of the star.

Essentially a typical star would need to be 8+ Solar Masses (O), so it needs to have a certain threshold of mass before it would be able to explode into a super nova. But, it there is a process where the star could lose its weight and essentially, it’s mass, then a supernova explosion would be averted. An example of such a thing would be the interaction of other star, solar flares (Coronial Mass Ejection). Though the opposite can be said as-well, where other explosions (Supernova) can add to the mass of a star, making its total mass even larger, thus making stars that are just below the Chandrasekhar limit, being made supernova eventually. Currently the star that is more close to us and is in chance of actually detonating into a supernova is Betelgeuse in the Orion constellation and currently the 8th brightest star in the Night Sky.
