Supernovae have no effect on Earth.


Supernovae occur so far from Earth that the radiation that reaches Earth does not damage our atmosphere. However, if one supernova occurred at a distance, say a 100 light years, it would damage the ozone layer. But thankfully, stars that supernovae are damaging to Earthare more than a 100 light years away.
