a super giant star two hundred times bigger than the sun utterly obliterated by runaway thermonuclear reactions . . . unleashed a cloud of radioactive material

  From the comments it seems that 'bigger' equals mass, and 'fifty times the size' refers to volume. I was confused too.

    That's probably true, but there's also the fact that the majority of the mass of the star escapes as gamma rays and neutrinos, so mass isn't (locally) conserved in these events.
