What is created as a result of a supernova implosion?

A supernova implosion occurs when a massive star exhausts its nuclear fuel and can no longer support itself against gravitational collapse. This process leads to a dramatic explosion that can outshine entire galaxies for a short period. The end result of such an implosion can often be the formation of a black hole.

Specifically, if the core of the star that remains after the supernova is more than about three times the mass of the Sun, the gravitational forces are so strong that they compress the core to a point where not even light can escape. This point is known as the event horizon, defining the black hole.

While other astronomical objects like red giants, main-sequence stars, and planetary nebulae play important roles in stellar evolution, they do not result from the specific process of a supernova implosion of a high-mass star. A red giant represents a different evolutionary stage, while main-sequence stars are still in their stable burning phase, and planetary nebulae typically result from the death of lower-mass stars rather than the explosive end of a massive star. Therefore, the formation of a black hole is the most accurate outcome associated with a supernova implosion.
