A massive iceberg the size of Delaware has broken free from Antarctica and is floating in the sea.
Earlier Wednesday, scientists announced that the 6,000-square-kilometer (about 2,300 square miles) iceberg had come loose, after satellites detected it had calved off the Larsen C ice shelf on the Antarctic Peninsula.
Scientists had anticipated the breakup since a massive crack first opened up in the Larsen C ice shelf back in 2014. The crack grew rapidly, and by the end of last week, a roughly 3-mile sliver of ice was all that connected the iceberg to the shelf.
