It's Aliens

The Daily Mail (U.K.) reports astronomers are seeing brief, bright flashes of light from far distant galaxies. Hat tip to Lucianne.com for the link.

Astronomers have spotted 72 extremely bright and quick events flashing in the sky - and they have no idea what they are. The mysterious explosions are similar in brightness to supernovae, which are the gigantic explosions of dying stars.

But supernovae can be seen lighting up the sky for months at a time. However, the latest 72 mysterious explosions 4 billion light years away can only be seen from a week to a month.

What's causing these brief, bright lights? My guess: somebody out there has developed a Death Star™ (i.e., planet killer) and is using it in an interstellar, perhaps interspecies, war of annihilation. Each of those 72 flashes is a planet being consumed in thermonuclear fire, and perhaps the simultaneous death of an intelligent species.
