What do you call a star that blows up because of it's size and heat?

A star that blows up due to its size and heat is called a supernova. This explosive event occurs when a massive star exhausts its nuclear fuel, leading to a collapse of its core followed by a dramatic explosion. Supernovae can outshine entire galaxies for a short period and play a crucial role in dispersing elements into space, contributing to the formation of new stars and planets.
