A chunk of ice the size of the island nation of Singapore broke off of the continent of Antarctica late last month and is currently adrift at sea.
NASA satellite images taken on Oct. 28 and Nov. 13 show the before and after images of the break.
A crack was first detected in the pine island glacier years ago. Gradually it deepened into a rift and now, a full detachment from the continental mass.
Scientists say the city-sized iceberg measures roughly 35 by 20 km. (22 by 12 mi.) and that it is anybody's guess whether the iceberg will stay trapped in Pine Island bay or get set adrift in the Southern Ocean.
