They can take more geometrically pleasing shapes than their more rugged, non-tabular counterparts.

Kelly Brunt, an ice scientist with NASA and the University of Maryland, said such icebergs are fairly common.

Two squared-off icebergs appear in this image, one over to the right and the other above the plane.

NASA also shared a picture of a perfectly triangular block of ice found nearby and taken on the same trip, Operation Icebridge.

What happened:NASA posted a photo on Twitter of an iceberg that looks like a rectangle.

Images of the unusual icebergs were captured on NASA's IceBridge flight, an airborne survey of Arctic and Antarctic ice yielding detailed, three-dimensional views of ice sheets, ice shelves and sea ice.

And these tabular icebergs can be enormous - hundreds or even thousands of square kilometres, such as the 11,000 square kilometre (4,200 square mile) B-15, the largest iceberg ever recorded.

The BBC explains that the iceberg probably separated recently from the Larsen C ice shelf, and such new breakaway bergs are sometimes "geometrically" shaped. The berg's sharp corners indicate wind and waves haven't had much time to break it down, Brunt said.

The oddly satisfying phenomenon was discovered near the Larden C ice shelf in the Antarctic Peninsula.

Using research aircraft, the operation intends to document the Earth's polar ice.

"What makes this one a bit unusual is that it looks nearly like a square", she added.

Not satisfied with blowing our minds once, NASA released an image on Monday showing a second rectangular iceberg.

Experts have said if all of the Larsen C was to break free it could add another 4 inches (10 cm) to global sea levels over the years - however the breakage may not be down to climate change.

According to Brunt, it is hard to determine the size of the iceberg in the photo, but it's likely more than a mile across.

Just past the rectangular iceberg, which is visible from behind the outboard engine, IceBridge saw another relatively rectangular iceberg.
