Any civilization capable of sending missiles across the galaxy should be more than capable of simply sending a tight beam of gamma radiation to sterilize the planet. No need for earth shattering explosions. Just a flood of radiation engulfing the planet for a minute or two and everything not buried a mile underground will be dead. There would be no warning either.

And that's if they don't bother to just blow up the sun.

I like the just speed up a small, really heavy object to a very high speed approach of The Three Body Problem books.
