In practical terms it's a bad idea, because supernova events are rare but new players are joining the game all the time. So for every player to have a chance at this experience we'd have to have a supernova go off somewhere every few months. Now we have more than enough stars for that to happen even in the inhabited bubble, but it would not be terribly realistic.
I would suggest the alternative idea of regularly recurring events, such as huge unpredictable solar storms requiring the temporary evacuation of scientific outposts, or large asteroids or comets threatening to impact on colonies unless they are diverted/destroyed/mined into oblivion before they hit.
