The US space agency NASA has unveiled a unique iceberg shaped rectangular cake that took pictures during a trip in Antarctica lasting several weeks.
Images published by the agency on Twitter showed a rectangular shape of the iceberg, an unusual form of glaciers in this region, usually with pointed tops and uneven edges.
NASA has spotted the rectangular iceberg just off the east coast of the Antarctic Peninsula, near the Larsen Sea ice shelf, where NASA is conducting a survey that began on October 10 and runs until Nov. 18.
The "iceberg cake" is one of two types of glaciers that are classified according to shape, called unplanned glaciers, which are large ice sheets with vertical sides and flat peaks.
NASA's current trip to Antarctica aims to carry out an airborne polar ice survey to obtain a three-dimensional vision, which will provide vital information on how to change it over time.
"We often see icebergs with relatively straight edges, but I've never seen a mountain like this," said Jeremy Harbeck, a NASA scientist overseeing the project.
These icebergs can have a large area, possibly hundreds or even thousands of square kilometers, such as an iceberg of 11,000 square kilometers, the largest ever recorded iceberg.
