An exploding star is a catastrophe on a cosmic scale, but here on Earth we’re safe from such astral disasters—for now
Kurzgesagt made a fairly entertaining video about the effects of a supernova on Earth at different ranges:
The article says
a supernova would have to be less than about 160 light-years from Earth to inflict this sort of damage.
