This photo taken on November 6 and released on November 12 by the Australian Antarctic Division shows a giant iceberg, as it drifts past the Australian sub-Antarctic territory of Macquarie Island. The giant iceberg, twice the length of Beijing's "Bird's Nest" Stadium, has been spotted floating off Australia and could be headed for New Zealand, scientists said on Thursday.(AFP/AAD-HO/File/Tessa Bickford) Thu Nov 12, 12:03 PM ET
