A large metallic ball fell out of the sky on a remote grassland in Namibia, prompting baffled authorities to contact NASA and the European space agency. Several such balls have dropped in southern Africa, Australia and Latin America in the past twenty years. Two are see here in this video.

The sphere was discovered mid-November, 2011, but authorities first did tests before announcing the find. Police deputy inspector general Vilho Hifindaka concluded the sphere did not pose any danger. "It is not an explosive device, but rather hollow, but we had to investigate all this first," he said.
