The Star

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:

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.
