This iceberg is perfectly rectangular-here's why

They were often geometrically-shaped as a result, she said.

NASA's Operation IceBridge, which monitors polar ice using plane surveys, has been going on for a decade.

NASA calls the captured design "a tabular iceberg, a type of iceberg both broad and flat", USA Today reports.

"If you look at the recent icebergs that calved of iceberg A-68 (near Larsen C), you will see that many of them have pretty "rectangularish" shapes".

An expert said the sharp edges of the iceberg likely indicate that it has recently detached from an ice shelf and was photographed before the sea and wind could wear down its edges.

Quoting glaciologist Jan Lieser, who is with the Antarctic Climate & Ecosystems Cooperative Research Centre, the report stated that straight lines and sharp angles on ice sheets are a known phenomenon. At their largest, tabular icebergs can extend for hundreds of miles in length, and reach hundreds of feet below the surface.

Turkey to reveal details of probe into Khashoggi's killing
Turkish officials gave CCTV footage to CNN that showed a man wearing Khashoggi's clothes exiting the Saudi consulate on october 2. Prior to Jubeir's interview, a senior Saudi official laid out a version that itself contradicted earlier explanations.

NASA scientist Kelly Brunt told LiveScience, "What makes this one a bit unusual is that it looks nearly like a square".

"I was actually more interested in capturing the A68 iceberg that we were about to fly over, but I thought this rectangular iceberg was visually interesting and fairly photogenic, so on a lark, I just took a couple of photos", Mr Harbeck said. This berg hasn't been measured yet, but Brunt says it's about one mile across, which isn't not particularly large.

NASA captured an image of an iceberg that looks like a ideal rectangle.

The visible part of the iceberg only represents 10 percent of the entire mass, Fox News reports.

The northern Antarctic Peninsula is ice-covered and mountainous. As it calved, the iceberg may have been smooth and flat underneath, but ocean currents would have quickly changed it.

In any case, users stressed that the iceberg certainly looked interesting, with several suggesting it reminded them of a scene out of Stanley Kubrick's 2001: A Space Odyssey.
