NASA explains the origin of the mysterious rectangular iceberg in Antarctica

After analyzing satellite data, the US space agency NASA described how the rectangular iceberg detected in October of this year was formed close to Antarctica, whose shape is too perfect and surprisingly smooth, as if it had been cut with a band saw.

The unusual ice floe was photographed by Jeremy Harbeck, a specialist in a NASA research program.

Initially it was assumed that the iceberg was newly formed, however, as shown by satellite data, in fact, it was last year.

According to the space agency, the iceberg broke away from the Larsen ice shelf in November 2017, just a few months after A-68, a much larger ice block, too. it separated from the glacier. The iceberg, which was about four kilometers long, moved north.

While navigating a narrow passage between the northern tip of the A-68 iceberg and a rock area near the structure called Brawden Ice Rise, it has probably assumed such an unusual shape due to the continuous shocks of ice, they say the experts.

Over time, the iceberg lost its rectangular shape and began to resemble, rather, a trapezium. According to NASA, it seems, the iceberg will continue to move north, where it will eventually melt.

Moreover: in Antarctica they find signs of a possible catastrophe
