The nearly perfectly rectangular iceberg spotted by NASA's Operation IceBridge is nothing unusual or unnatural, CNN reported. Tabular icebergs form when they split off from ice shelves, and sometimes the cracks that divide them from their parent ice form in geometric patterns, including straight lines.
The flight originated from Punta Arenas, Chile, as part of a five-week-long IceBridge deployment, which began October 10 and is scheduled to conclude November 18. Sitting amid a chaotic jumble of floating ice, it looks perfectly rectangular, as though it was deliberately cut.
The angular berg is called a tabular iceberg.
The spectacular photo of a massive rectangular iceberg with perfectly pointed edges, taken by a NASA research aircraft last week, left people scratching their heads as to how on earth this was possible.More news: Broncos QB busted again in odd trespassing case
"[Icebergs] look like these lovely pristine white things from a distance, but if you look a little closer, they're really mangled and full of cracks", she says.
NASA scientists spotted this "tabular iceberg" floating near the Larsen C ice shelf in Antarctica.
The yet-to-be-named iceberg snapped off the Larsen C ice shelf, which calved an iceberg the size of DE past year.

The size was hard to guess, Ms Brunt said, but suggested it was likely more than a mile long.
But, he added that "the presence of icebergs like these are a sign of increased calving".
A NASA spokesman said: "It will yield an unprecedented three-dimensional view of Arctic and Antarctic ice sheets, ice shelves and sea ice".
The Larsen C ice shelf is being closely monitored by scientists after showing signs of breaking up. "I should think we will see some interesting collisions with the ice shelf in the next few months".More news: Qualcomm introduces 11nm Snapdragon 675 with new CPU
