Nasa spots new iceberg three times the size of Manhattan in Antarctica

Nasa has spotted an enormous new Antarctic iceberg while on a mission to survey the region's shifting sea ice and glaciers.

It marked the first time anyone had laid eyes on the massive expanse of ice, which was said to have broken off Pine Island Glacier in late October and was first observed by satellites.

The US National Ice Center estimates the iceberg, dubbed B-46, representing 66 square miles (87 square miles) in size, around three times the size of Manhattan.

However, satellite images have already begun to break into smaller chunks.

The iceberg's discovery comes shortly after Nasa released images of two separate "tabular icebergs" – ones with completely rectangular shapes and smooth edges.
