• The Star

    From Stephen Wolstenholme@21:1/5 to All on Fri Sep 18 10:59:22 2015
    One of my young carers came in when I was looking at the picture at http://apod.nasa.gov/apod/ap150917.html

    She asked what it was and I replied that it was the result of a star
    exploding. She replied that it was lucky there are no stars near us. I
    pointed at the Sun. Now she is worried about it exploding.

    It isn't heavy enough to do that. It will eventually expand to a red giant and cook the Earth but she'll have to wait about 4bn years...

    On the other hand there is a list here of supernova candidates which are relatively close in astronomical terms: https://en.wikipedia.org/wiki/List_of_supernova_candidates

    Betelgeuse, the largest star near us, is due to explode but probably not in
    our lifetimes. But, in fact, no one really knows. It could be tomorrow or a million years in the future. http://earthsky.org/brightest-stars/betelgeuse-will-explode-someday

    Cheers, Alastair.
