WebJan 10, 2024 · To understand a supernova, it's important to know a few things about stars. They spend most of their lives going through a period of activity called being on the main sequence. It begins when nuclear fusion ignites in the stellar core. It ends when the star has exhausted the hydrogen needed to sustain that fusion and begins fusing heavier elements.
