'It Was Aliens': Twitter Puzzled by Perfectly Geometrical Antarctic Iceberg

Covering an estimated 5,800 sq km, the Larsen C ice shelf extends along the east coast of the Antarctic Peninsula from Cape Longing to Smith Peninsula.

UMBC JCET Scientist at NASA Goddard Space Flight Center, Christopher Shuman, who has been watching the Larsen C Ice Shelf explained that the main iceberg (which was the size of about the size of the state of DE when it split from the shelf in July) has had a previous series of collisions, resulting in larger and smaller fragments.

NASA has discovered an incredible 1.6 kilomtre-long, perfectly rectangular iceberg floating in the Antarctic.

Well here's something you don't see everyday: an iceberg so unbelievably geometric in shape you'd think it was deliberately carved with a huge chainsaw.

Scientists from Project MIDAS - a British Antarctic Survey project involving researchers from several British universities - said a year ago that they feared the entire ice shelf could become unstable.

The study uses research aircraft to capture three-dimensional images and monitor annual changes in thickness of sea ice, glaciers and ice sheets, with the aim of better understanding connections between polar regions and the global climate system.

In an interview to Live Science Kelly Brunt, a glaciologist at the University of Maryland and NASA was left stunned by the "unusual" discovery.

It's described as a "tabular iceberg" - with steep sides and a flat top, typically formed by "snapping off" from an ice shelf, experts say.

The agency also captured a triangular berg drifting in the Weddle Sea.

She said there were two types of iceberg. "And then you have what are called 'tabular icebergs'".

The size was hard to guess, Ms Brunt said, but suggested it was likely more than a mile long.

"In the open water, grease ice is forming".

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