Brightest Galactic Flash Ever Detected Hits Earth

Imagine a star exploding in the sky and appearing as bright as a full moon. Now imagine that it's, say, Jupiter that does that. It would have to be a pretty big bang to appear so bright when Jupiter is 724 million miles from earth. Now imagine that the star that blew up is 50,000 light years away; that's 300,000,000,000,000,000 miles away. (300 quadrillion miles) In the Gamma ray band, that's how bright it appeared, and it was strong enough to disrupt our upper atmosphere a bit.
The article says that if it had been witin 60 trillion miles of us, it could have caused a mass extinction on earth.
Now, THAT'S a big bang!
