NZ HERALD - 6kg ball drops on Namibia - Strange But True, Dec 24, 2011

"A large metallic ball has fallen out of the sky on a remote grassland in Namibia, prompting baffled authorities to contact Nasa and the European space agency.
The hollow ball with a circumference of 1.1m was found near a village in the north of the country some 750km from the capital, Windhoek, according to police forensics director Paul Ludik.
With a diameter of 35cm, the ball has a rough surface and appears to consist of "two halves welded together".
It was made of a "metal alloy known to man" and weighed 6kg, said Ludik."
