The Connection Between Supernovas and Mass Extinctions
A type two star with a mass greater than 40 solar masses will turn into a black hole when it reaches the end of its life, and this can cause mass extinctions on Earth by affecting the ozone layer and triggering a climate change.

Our sun will never go supernova, but if a nearby star did, it could potentially cause a climate change on Earth leading to a mass extinction event. Evidence of past supernovae can be found in radioactive iron 60 buried on the seafloor.
