On: How many supernova explode every year?

[crag-jene]

Not all stars can go supernova. Sol will never go supernova. Only very massive stars can—or stars that become very massive by absorbing other stars.

Binary white dwarf systems can also go supernova, even if the combined mass is not that large as far as stars go.
