A gargantuan green dragon hisses in the sky over Iceland. Either “Game of Thrones” really upped its production budget for its final season, or the sun belched a barrage of charged particles into our atmosphere again.

As much as any of us would like to see a real dragon breathe flames into the winter sky, buzzkill NASA blames solar activity — as usual — for the writhing, “fire-breathing”- aurora that loomed over Iceland earlier this month.

Of course, I like the GAME OF THRONES scenario.
