Well to start, our universe began with an explosion of space itself - The Big Bang.
Big Bang is an expansion of the space and as it expands, it cools down
Few minutes after the Bigbang , Light elements like hydrogen, helium and a trace of Lithium are formed and its called the BIGBANG NUCLEOSYNTHESIS
There is a small, young, yellow star names Stellar
NOW LET'S FOCUS ON ME. HI! MY NAME IS STELLAR 333
Stellar is made up of hydrogen fueled by the energy from fusion of hydrogen nuclei to helium
Then a successive nuclei occured until it becomes a Giant Red Star
A production of elements will happen and it only stops when IRON was formed because it is a stable nucleus and it cannot undergo nuclear fusion
At this point, Stellar is already exhausted because it has little nuclear fuel now. Its core starts to collapse leading to the explosion of stellar which is called the SUPERNOVA
