The Nearest Supernova Candidate To Earth: IK Pegasi 55
The Bad Astronomer writes "What's the nearest star to Earth that can explode as a supernova? Spica, at 260 light years away, is the nearest massive star that can explode, but IK Pegasi — a Sirius-like binary composed of a normal star and a white dwarf — will also one day blow. At a distance of 150 light years, it's truly the closest supernova candidate. Happily, that's too far away to damage the Earth when it goes off — and it won't explode for millions of years at least, by which time it'll be even farther away. Either way, we're safe... for now."

I'll have to go down to the local planning office in Alpha Centauri and see if they've got a permit for a supernova that close to the planned hyperspace bypass...
