So if our Star, the sun, has a massive explosion, we are toast? Good to know.
I believe the current theory as far as our Sun goes is that it will eventually run out of fuel and shrink down to a white dwarf star (becoming about the size of Earth), but first it goes through a red giant phase, expanding in our solar system to the point where most of the planets close to it (including Earth) will be swallowed entirely.
Also, it would apparently take a 25 magnitude quake to destroy the Sun. And that star quake was 7^10x stronger than that.
