The biggest iceberg on Earth is heading toward a remote island, creating a potential threat to penguins and seals inhabiting the area.

The trillion-ton slab of ice that scientists call a "megaburg" broke off from the Antarctic’s Filchner Ice Shelf in 1986. Scientists catalogued it under the name A23a. It was stuck at sea for decades but confirmed to be moving again more than a year ago.

The world's largest iceberg, A23a, is on a crash course towards South Georgia, threatening millions of penguins and seals.

The world's largest iceberg looks set to collide with a group of remote islands in the southern Atlantic, risking the safety of wildlife in a region renowned for rich biodiversity that surpasses even that of the Galapagos.

The world’s largest iceberg, A23a, is heading north from Antarctica toward South Georgia, a British Overseas Territory in the southern Atlantic Ocean. In the past, giant icebergs grounding near South Georgia have caused devastating consequences,

The world’s largest iceberg is still on the move and there are fears that it could be headed north from Antarctica toward the island of South Georgia. The iceberg, called A23a, was previously “trapped” spinning around an undersea mountain for several months,

The colossal iceberg A23a, towering at 40 meters and spanning an area greater than the Australian Capital Territory, is now advancing towards South Georgia Island, a remote British territory near Antarctica.

The trillion-ton slab of ice named A23a could slam into South Georgia Island and get stuck or be guided around it by currents.

The world's iceberg is heading for South Georgia—a wildlife haven in the South Atlantic—and scientists are worried.

The world's biggest iceberg -- more than twice the size of London -- could drift towards a remote island where a scientist warns it risks disrupting feeding for baby penguins
