Supernova candidate

  1. Jul 23, 2003 #1
    Is there any supernova candidate in the neighbourhood of the earth, near enough to be able to annihilate us due to the radiation?

    Which is the minimum distance a supernova can stay whithout friying us?

    anybody knows?

    Off the top of my head, I don't think there are any candidates close enough to be of great concern. Correct me if I'm wrong.

    In general, any planets of a star going supernova are going to be deep fried...

    ...planetary systems a few light years away might get very nervous...

    ...this same astronomer (all links herein) estimates the danger zone at around 10-50 light years...

    As for the Earth, Betelgeuse might put on an interesting show but I think we'll be ok...
