This MODIS image taken by NASA&#039;s Aqua satellite on Nov. 10, 2013, shows an iceberg that was part of the Pine Island Glacier and is now separating from the Antarctica continent.  What appears to be a connection point on the top left portion of the iceberg is actually ice debris floating in the water. The iceberg is estimated to be 21 miles by 12 miles (35 km by 20 km) in size, roughly the size of Singapore. (Credit: NASA)
