WATCH: World's Largest Iceberg Breaks From Antarctica

A giant piece of ice that broke off from Antarctica is now the world's largest iceberg.

The European Space Agency says the iceberg calved from the western side of the Ronne Ice Shelf in the Weddell Sea this week.

The iceberg looks like a giant ironing board and is nearly 80 times the size of Manhattan.

It's more than 100 miles long and about 15 miles wide.

Experts say iceberg calving is a common, natural occurrence and this one isn't linked to climate change.
