A new satellite photo has revealed that the "megaberg," A23a, is beginning to break apart, spawning thousands of smaller ice chunks around the Antarctic island of South Georgia.

But the world's largest iceberg, known as A23a, is starting to crumble. Satellite images reveal that an enormous chunk has broken off the megaberg, which has been steadily travelling north in the ...

About the size of Rhode Island, the iceberg known as A23a got stuck in an ocean vortex this summer, spinning in place for months. Now, it's free, and heading back into open Antarctic waters.

Satellite images showed that the closest edge of the roughly 3000sq/km iceberg had stopped more than 70km from the island in late February. It remains unclear whether the iceberg is stuck for good.

Scientists now have good numbers to describe the true scale of the world's biggest iceberg, A23a. Satellite measurements show the frozen block has a total average thickness of just over 280m ...

About the size of Rhode Island, the iceberg known as A23a got stuck in an ocean vortex this summer, spinning in place for months. Now, it's free, and heading back into open Antarctic waters.

Scientists use a radar satellite to take a "tape measure" to the world's biggest block of ice.

The world’s biggest iceberg appears to have run aground roughly 70km from a remote Antarctic island, potentially sparing the crucial wildlife haven from being hit, a research organisation said.
