I was more thinking a question out loud. Supernova tend to happen on larger stars that burn brightly for (in astronomical terms) a short time. That gives life a shorter time to establish, but if it did happen then someone who knows that side of physics can probably work out where the Goldilocks zone which is "just right" for supporting life would be a on a star in that size range, and then what happens to planets in that orbit when the star blows.
TBH the journey through space would be pretty intense so I have to wonder if any useful biochemistry could make a journey of thousands of years. Just reading up on how fast the SpaceX Tesla is going to fall apart was quite interesting.
But in pure numbers there are so many stars and planets out there that one in a billion chances start looking like a certainty to happen somewhere. That does make for fun sci-fi stories both in terms of what humans might be capable of and what else might be out there.
