NASA shares photograph of a peculiar rectangular iceberg in Antarctica

NASA recently posted a picture of an iceberg in Antarctica, but it is not a conventional one. While icebergs with straight edges are not unusual, icebergs with two straight edges that meet at a right angle-like a rectangle— are certainly peculiar. This photograph was snapped in 2018 as part of Operation IceBridge, NASA's longest-running aerial survey of polar ice.
