The world's largest iceberg is drifting beyond Antarctic waters and satellites are tracking its movement from space.
The iceberg, called A23a, has broken loose and is moving past the northern tip of the Antarctic Peninsula after being grounded for more than three decades. Recent satellite images reveal that the iceberg, weighing nearly a trillion tons, is drifting at a rate of three miles each day, aided by strong winds and ocean currents, Smithsonian Magazine reported.
