ANTARCTICA — A ridiculously rectangular iceberg was spotted last October 16, and there's only one question on everyone's minds: is it real?<br /><br />NASA's Operation IceBridge photographed a tabular iceberg during a flyover over Antarctica. It's believed to have fractured from the Larsen C ice shelf in May, reports the Washington Post.<br /><br />Unlike an angular iceberg which usually has just the tip sticking out, tabular icebergs have a flat surface and steep, vertical sides.<br /><br />NASA and University of Maryland scientist Kelly Brunt explained to LiveScience that tabular icebergs form when an ice shelf grows out like a fingernail and calves off, often resulting in straight, geometric lines<br /><br />The iceberg's sharp corners are an indication that its new, since wind and waves usually round it out.<br /><br />The iceberg hasn't been measured, but is likely to be more than a mile across. It's definitely not the biggest one ever recorded, however, that distinction belongs to Iceberg B-15, which was 183 miles long and 23 miles wide.
