A Machine Legacy

The electrical impulses we observed on … are the lingering result of a bizarre, machine extinction event. Only after our sensors were tuned to compensate for such intense electromagnetism could we observe the full extent of devastation here. The planet looks to have been settled by machines many decades ago, whereupon they displaced or eradicated an existing civilization. None now survive from either empire, with almost the entire settlement reduced to slag by an act of sabotage or warfare. Despite the sophistication of this former colony, there is little hope of salvage here. We predict the runaway 'EM' fields will burn out in approximately a century. Until then, … remains a singularly hostile graveyard.
