One of the largest icebergs ever recorded has broken free of Antarctica. A crack in an Antarctica's Larsen C ice shelf is responsible for calving the colossal new iceberg, which is roughly the area of Delaware state and the volume of Lake Michigan.

Researchers noticed the distinctive rift in Antarctica's ice in 2010, which has grown rapidly since 2016. The iceberg calved between July 10 and July 12, researchers said.

"Breaking news! The iceberg has fully detached from Larsen C - more details to follow soon," Martin O'Leary a glaciologist at Swansea University, wrote in a tweet early Wednesday morning for Project MIDAS.

A NASA Earth-observing satellite called MODIS was among the first to photograph the colossal ice block freed of Antarctica's grasp. It appears the iceberg has largely stayed intact.
