It's taken roughly five months, but a massive iceberg has separated from Antarctica's Pine Island Glacier. According to NASA's Earth Observatory, the estimated size of this iceberg, named B-31, is around 660 square kilometres (33 km long by 20 km wide) – a city-sized block of ice that has slowly migrated away from the continent, and is now floating out to sea. Take a look at some massive icebergs afloat in the oceans. Photo: File photo of an iceberg floating near a harbour in the town of Kulusuk, east Greenland August 1, 2009.

Irene, the first hurricane of the Atlantic storm season, brought torrential rains and winds to Puerto Rico, downing trees and powerlines and flooding streets. The expected path will bring Irene through the Bahamas and is likely to hit Florida and up the east coast of the U.S. (Photo by NOAA via Getty Images)
