A 300-foot-wide, 70-mile-long rift in Antarctica's Larsen C Ice Shelf, as seen in November 2016.
A crack in an Antarctica's Larsen C ice shelf birthed one of the largest icebergs ever recorded, scientists announced Wednesday morning.
"The calving of this iceberg leaves the Larsen C Ice Shelf reduced in area by more than 12%, and the landscape of the Antarctic Peninsula changed forever,"Adrian Luckman and Martin O'Leary, two glaciologists at Swansea University, wrote in a July 12 blog post for the MIDAS Project, which has been monitoring the ice.
They also said the iceberg weighs more than a trillion metric tonnes.
The following size comparisons will give you a sense of just how colossal this new iceberg is.
