NASA recently shared the picture of an iceberg in Antarctica: what impressed and attracted attention was the rectangular and nearly perfect shape, which suggested that it had been cut deliberately.
The monolithic ice block floats beside the Larsen C ice floe and its angles are 90 degrees.
D & # 39; yesterday #IceBridge flight: a tabular iceberg sits to the right, floating between the sea ice, just off the Larsen ice floe C. The acute angles and the flat surface of the iceberg indicate that it probably comes from the sea ice. to be calved from the pack ice. pic.twitter.com/XhgTrf642Z

The images shared by NASA were taken as part of Operation IceBridge, a mission to capture images of Earth's polar regions to understand the evolution of ice in recent years.
According to Forbes reports, although the iceberg is rather strange to see, it is a completely natural phenomenon.
The explanation is that the part of the angular icebergs we see is usually the end that comes out of the water. But there is another type of iceberg called tabular.
Tabular icebergs have almost vertical sides and flat tops. Usually, they are detached from the pack ice and, in the case of clear terrain, the angles can be close to 90 degrees, as in this recently captured case.
Kelly Brunt, a NASA scientist, told Live Science that it is likely that this iceberg is not very old, because the wind, the waves and the seawater will eventually wear out the sharp edges and round them up.
The iceberg in question has not been measured, but experts say that this type of iceberg can be very bulky: the largest in the world is the Iceberg B-15, 183 km long and 23 km wide. This tabular iceberg, larger than the island of Jamaica, was detached from the Ross ice floe in 2000.
