Here's why:
* Our Sun is not massive enough: For a star to explode as a supernova, it needs to be at least 8 times more massive than our Sun. Our Sun is a relatively small star and will eventually become a white dwarf, not a supernova.
* Stars explode far away: Supernovae are incredibly powerful events, but they happen in distant galaxies, far beyond our solar system. The closest supernova observed in recent centuries was SN 1987A, which occurred in the Large Magellanic Cloud, a satellite galaxy of our own Milky Way.
