Harbeck was the one who spotted this flat-topped, sharp-angled, iceberg floating off Larsen C ice shelf, notes the report. Photo photographed from onboard the IceBridge mission, which specializiruetsya on monitoring changes in polar ice. Previously, NASA has launched a project to search for extraterrestrial civilizations.

The rectangular iceberg itself seems to be freshly calved from Larsen C. This is the same ice sheet from which broke a massive, trillion-ton A 68 iceberg.
In a different photo (above), Harbeck captured both the edge of the now-famous iceberg, and a slightly less rectangular iceberg.
The photo of the rectangular iceberg was widely shared after it was posted on social media.
The second table also split the iceberg from the ice shelf, Larsen S.
The A-68 ice island is roughly the size of Delaware.
Scientists with NASA's Operation IceBridge released the original photo last week, but it only showed a portion of the odd iceberg.
Non-tabular icebergs are the ones we tend to think about in the more traditional sense, but our steep-sided and flat-topped friends have something in common with their more recognizable cousins: they likely take on a more geometric shape below the surface, making them just as hazardous for passing ships.
