Supernova thoughts

I want to understand ideas like nuclear fusion….inside stars—how hydrogen fuses into helium and on up the list of heavier atomic elements to eventually iron. At this point, the force of gravity that the star exerts is greater than its radiation and this event brings forth a supernova. The gaseous outer shell of the star comes crashing into the dense iron core creating this dramatic stellar explosion. Many more elements are cooked up at this point which makes them available to solar systems. Solar systems have all the available elements to create life, thanks to the supernovae. I’m dredging up things I learned a decade ago. Thanks to the internet we call learn more about hydrogen fusion but I learned this from watching videos like "Cosmos" from the library. If I'm even remotely correct in my understanding/recall here, I'm giving myself a fucking memory badge and a big thanks to the fantastic educator, Carl Sagan.
