... That only happens to much more massivestars ; stars that are 8 or more times the mass of the Sun. ... Instead of exploding, our Sun will swell massively when it runs out of hydrogen fuel, turning into a red giant star. ...
... But long ago, before the star collapsed, it was a star something like the Sun, though much more massive and hotter. ... Fusing iron rings the death knell for a massivestar. ...
