The excellent PBS Spacetime - a physics and cosmology education channel - has released a new video detailing the effects and likelihood of supernovae in our stellar neighborhood.

    Spacetime is really a wonderful channel. The way they make actual quantum physics comprehensible to normal people is incredible.

    I can answer that: the Sun going supernova would most likely trigger a mass-extinction event on Earth. Time to start writing grant letters

        We have a lower bound of 1 AU then!

        It is estimated that a Type II supernova closer than eight parsecs (26 light-years) would destroy more than half of the Earth’s ozone layer. -Wikipedia

        So we probably wouldn’t want that to happen either, but I don’t know if that would cause specifically an extinction event.

        Also the star most likely to cause a near-earth event is IK Pegasi which is about 150 light years away.
