The biggest iceberg in the world, named A23a, appears to have run aground after drifting around the Southern Ocean near Antarctica since 2020.

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

The colossal iceberg A23a – which is more than twice the size of Greater London and weighs nearly one trillion tonnes – has been drifting north from Antarctica towards South Georgia island since 2020.
