What would happen if a gamma ray burst from a supernova hit Earth from differing distances?
That sounds pretty scary. What if the gamma ray burst comes from, say, 1,000 light years away?
A gamma ray burst from a supernova 1,000 light years away would still have significant effects on our planet. It could ionize our atmosphere, damage our satellites and electronic infrastructure, and cause loss of life among already vulnerable populations. However, there may be some time to prepare and mitigate the effects, as the gamma ray burst would take 1,000 years to reach Earth.
