Senior support scientist Jeremy Harbeck noticed the iceberg just off the Larsen C ice shelf.
NASA started this year's Operation IceBridge in October and some of the images show not just the majesty of southern polar ice, but also some of the rather unusual and freakish shapes that icebergs can take.
When the IceBridge scientists reveal the new photos of this, it has shown that the iceberg's true shape and form that it came to know that this is not the flawless rectangular.
You may recall the first image, which was taken by the NASA's IceBridge, a fleet of research aircraft dedicated to studying Earth's polar ice by measuring annual changes in thickness of sea ice, glaciers, and ice sheets. The A-68 iceberg can also been seen in the distance.
Flights are conducted over Greenland from March to May and over Antarctica in October to November.
The scientist who all are involved in this operation has now released the original photo of that rare rectangular iceberg which was taken in the last week. "I often see icebergs with relatively straight edges, but I've not really seen one before with two corners at such right angles like this one had". The photo was taken on October 14, 2018, just two days before Operation IceBridge captured its now-famous photo of the iceberg.
The A-68 ice island is roughly the size of Delaware.
NASA has spotted a second strikingly rectangular iceberg in Antarctica.
