Yes, a supernova is generally considered to be the death throes of a massive star. When a massive star exhausts its nuclear fuel, the core can no longer sustain the fusion reactions that generate energy. As a result, the star undergoes a series of complex processes that lead to a supernova explosion. So, in a sense, a supernova can be thought of as the grand finale of a dying star. However, it’s important to note that not all dying stars become supernovae. Stars with lower masses, like our Sun, end their lives in a different manner, forming a white dwarf instead of undergoing a supernova.
