Nearby, Recent Interplanetary Collision Inferred

Posted by kdawson on from the when-worlds-collide dept.

The Bad Astronomer writes about a new discovery by the Spitzer Space Telescope, which detected signs of an interplanetary smashup only 100 light-years from here, and only a few thousand years ago. There's a NASA-produced animation of the collision between a Mercury-sized planet and a moon-sized impactor. The collision's aftermath was detected by the presence of what are essentially glass shards in orbit around the star. Here's NASA's writeup.

    The civilization that was living in that planet is traveling to a little blue planet that was nearby at a modest 100 light years. Invasion is scheduled for next Tuesday.

      Thankfully the invasion was called off when the aliens learned of mankind's secret weapons: lawyers, building permits and environmental impact statements. Said Fleetlord Atvar, "We came here looking to save our race, not to spend the next two hundred years filling out paperwork. We'll find a new home somewhere else, thank you very much."

      We are the United States Government! We don't do that sort of thing.

      Not the civilization per se. Just the infant son of the leading scientist who tried to warn them of the impact.

      My calculation predict that he'll land somewhere in Kansas.

    More efficient ways yes, but more satisfying?
