a super nova is not something that anything goes into. A SUPER NOVA is a part of a stars life cycle when it explodes. THEN all the dust and chips of the star reunite in a super nova remnent forming a COMPLETELY NEW STAR.

When a outer portion of a star explodes does it produce super nova?

no


What is an explosion that occurs at the end of a massive stars life?

its called a super nova.


Which star will be the next to go into super-nova?

It is difficult to predict which star will be the next to go into supernova as these events are unpredictable and can happen suddenly. However, some massive stars that are about to run out of fuel in our galaxy are potential candidates for a future supernova.


Is observed red shift in the light emitted by galaxies the more distant the more red shift the only evidence to conclude that the universe is expanding. Any more evidences. If so what are they?

During the time a super-nova in a very distant galaxy emits light, the first photons it emits have a head start over the last such photons -- ie, they begin to leave earlier. As such, there exists a distance between the first photons and the last photons. If that super-nova occurred over a billion years ago, AND if space is expanding over time, then the distance between the first photons and the last photons will also expand during the billions of years it takes for that distant super-nova to reach us. Because the last photons from a distant super-nova have a greater distance gap than the last photons from a nearby super-nova, distant ones will seem to last longer than nearby ones. The difference in time between the first photons and the last photons from a distant super-nova, as opposed to those from a nearby super-nova, match perfectly with the expansion in space seen in red-shift. In addition, if spatial expansion has been (more or less) constant since the earliest moments of our Universe, then at one time our Universe was far more dense than it is now, and that, at some point, the density dropped to the point where protons and electrons would combine into atoms, photons would no longer be absorbed by atoms, such photons would then be free to travel (and expand their wavelength) for billions of years, and we should observe almost perfectly isotropic microwave radiation coming from all parts of the sky. That was predicted in 1946, and observed eighteen years later -- exactly as predicted.


When does your sun explode?

the sun will explode when it has reach its age of life excepantcy which is at 10 billion years old the sun now it 4.573 billion years old so will go super nova or even hyper-nova in 4.437 billion years. In about a few hundred million years before its death the sun will enter its red giant phase then devour all the near planets and this could reach earth by then life cannot be sustainable
