Description
Supernova in a planetary system, artwork. A supernova is the explosive death of a massive star. It occurs when the star runs out of fuel at the end of its life. Without the nuclear reactions that powered it, it can no longer support itself against gravity, and it collapses. When it reaches a critical density, the outer layers rebound off the super-dense core in an enormous explosion. This would sterilise any planets that orbited the star.
