Regardless of the speculation, the sites look to be interesting places to explore on future missions.&lt;p&gt;In hypothesizing possible causes, I wonder about the relative size of the ejecta of a type 2 super nova. Given that the Uranium, on the planet originated in such events at some point, and the 4.7 billion year half life, one could imagine perhaps a modestly dense fragment cloud of U235 which was traveling at relativistic  velocity away from a Type II supernova, and it collides with the atmosphere of a planet in a far away star system. If the pieces were small enough they might simply heat up and impact the ground, however if they were massive enough, the shockwave of hitting the atmosphere might be sufficent to compress them into a supercritical mass. At which point the meteor would undergo rapid, and energetic, disassembly.</text></comment>
