You should know that there are no known supernova candidates within 30 light years of the Earth. The nearest candidate that is about to go supernova is Spica. And it's about 250 light years away.

According to the team's calculations, about one supernova happens every 400 million years within close enough vicinity to Earth that its radiation could impact the atmosphere.

They believe a supernova explosion close to Earth could be to blame for both the late Devonian and Ordovician extinction events, which occurred 372 and 445 million years ago respectively.
