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

Others said it reminded them of the monolith from "2001: A Space Odyssey".

Snapped by NASA's ICE mission, as part of Operation IceBridge, the giant tabular iceberg borne of the Larsen C ice shelf looks as though it was neatly cut from the wider ice shelf using a giant band saw.

The mile-wide "tabular iceberg" was seen floating among sea ice off the Larsen C ice shelf by one of the United States space agency's research planes.

Last year, a giant iceberg the size of DE - named A-68 - broke off from Larsen C, fuelling concerns it could be on the brink of collapse. Because the recently photographed iceberg was still sharp around the edges, NASA scientists said it's likely that this berg was cleaved off not too long ago.

Scientists are concerned about how ice at Earth's poles will fare with warming temperatures, and how melting ice will affect sea levels around the world, but Bartholomaus is hesitant to draw direct links to climate change. At their largest, tabular icebergs can extend for hundreds of miles in length, and reach hundreds of feet below the surface.

"And then you have what are called 'tabular icebergs.'" Kelly Brunt, an ice scientist with NASA and the University of Maryland, told Live Science.

"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 photos".

Members of the Operation IceBridge, NASA's decade-long airborne survey of polar ice, spotted two rectangular icebergs during a flight over the northern Antarctic Peninsula on October 16, 2018.

The calving of the huge iceberg reduced the size of the ice shelf by 12%.

It looks nothing like the craggy, uneven mass that sunk the Titanic, perhaps the most famous iceberg ever.
