Title: Cheap Astronomy – Dear CA #91: Supernovae. Again

Organization: Cheap Astronomy


Description: An explosive episode about supernovae. Things that make you go kablooie.

Why do supernovae explode once they start fusing iron?

Right now our Sun is fusing hydrogen into helium in its core. In maybe five billion years the situation will be all clogged up when the core has become mostly helium and the hydrogen fusion happens around it in a fusion shell.

What are binding energies?

Technically speaking a binding energy is the amount of energy required to disassemble a system of particles. So it’s actually a measurement of the amount of energy required to overcome the forces that bind particle systems together.
